A company that makes an email app that helps users encrypt their emails paid for fake reviews in an attempt to get more people to download its products, according to leaked emails obtained by Motherboard. An anonymous reader shares a report: The CEO of pEp, a Luxembourg-based company that makes the pEp email encryption apps for Android and iOS, commissioned a marketing company to write fake reviews that he himself wrote in the summer of last year. Leon Schumacher asked the marketing company Mobiaso to post 40 five-star reviews in English, French, and German to the Google Play Store. Schumacher included an Excel spreadsheet that contained the specific text that he wanted Mobiaso to use. "Super easy privacy," one fake review said. "One of the best mail applications. I have never had problems and I suggest it all the time to friends," another said. "Can we speed up today and do 12 ratings per day do 7 reviews per day (Please use the Texts below for the right countries (that I forwarded already per earlier e-mail)," Schumacher wrote in an email to Mobiaso. pEp, short for Pretty Easy Privacy, develops email encryption apps for both iOS and Android, where it has more than 10,000 installs, according to the stats on the Google Play Store. The company, through its foundation, also funded a new library to encrypt emails using PGP, the decades old technology that allows users to encrypt emails and other files. Mobiaso advertises "iOS reviews" and "Android installs" on its website. One of the services the company offers is App Store Optimization, or ASO, which includes fake reviews. The service has several price tiers, ranging from $160 to $450. Only the two most expensive tiers include fake reviews. "Each app developer/advertiser should remember that without a good ASO search optimization, your target audience wouldn't even find or open your app page," Mobiaso says.

Computer maker Acer has been hit by a ransomware attack "where the threat actors are demanding the largest known ransom to date, $50,000,000," writes Bleeping Computer: Yesterday, the ransomware gang announced on their data leak site that they had breached Acer and shared some images of allegedly stolen files as proof... In response to BleepingComputer's inquiries, Acer did not provide a clear answer regarding whether they suffered a REvil ransomware attack, saying instead that they "reported recent abnormal situations" to relevant law enforcement and data protection authorities... In requests for further details, Acer said "there is an ongoing investigation and for the sake of security, we are unable to comment on details." PC Magazine reports that data from Advanced Intel's Andariel cyberintelligence platform "was able to link the possible breach to the Microsoft Exchange issue."

The US Government Finally Gets Serious About IoT Security

著者: BeauHD
2021年3月19日 12:30
An anonymous reader quotes a report from IEEE Spectrum, written by Stacey Higginbotham: The IoT Cybersecurity Improvement Act of 2020 has given the nation an excellent framework that will influence IoT security across the world. So, what's to like about the law? Two things, as it turns out. First, the law isn't focused on securing individual devices by dictating password requirements or encryption standards, both of which will need to evolve. Instead, it relies on the National Institute of Standards and Technology (NIST) to set many of the requirements that government agencies have to follow when purchasing connected devices. These policies see overall security as the sum of several parts, requiring specific prescriptions for device, cloud, and communication security. NIST's initial rules include today's best practices, such as having an over-the-air device update program, unique IDs for each device so it can be identified on a network, and a way for authorized users to change features related to access and security. The recommendations also include logging the actions taken by an IoT device or its related app, and clearly communicating the specifics of a device's security to the user. The other reason to like the law is that it remains adaptive and flexible by requiring NIST to assess the best practices for cybersecurity for connected devices every five years. Hacks, by their nature, are also adaptive and flexible, and so preventing them needs equally adaptable legislation. That means buying IoT devices that can receive over-the-air software updates, for example, to patch up any newly discovered exploits."Unfortunately, the law isn't airtight," writes Higginbotham. She worries that the waiver process for devices needed for national security or research could be abused. There's also a loophole that exempts devices that are secured using "alternative and effective methods." The law doesn't clarify what agency evaluates the efficacy of these alternative methods or how that evaluation is made.

Security Researcher Hides ZIP, MP3 Files Inside PNG Files On Twitter

著者: BeauHD
2021年3月19日 09:45
A security researcher has discovered a novel steganography technique for hiding data inside a Portable Network Graphics (.PNG) image file posted on Twitter, a tactic that could be exploited by threat actors to hide malicious activity. Threatpost reports: Researcher David Buchanan heralded his discovery on Twitter earlier this week, accompanied by a photo declaring: "Save this image and change the extension to .zip!" He made the source code for his method available in a ZIP/PNG file attached to the image as well as on a post on GitHub that explains his methodology. Specifically, Buchanan demonstrated how he could hide both MP3 audio files and ZIP archives within the PNG images hosted on Twitter. The reason he was successful is because while Twitter strips unnecessary data from PNG uploads, they don't remove trailing data from the DEFLATE stream inside the IDAT chunk if the overall image file meets the requirements to avoid being re-encoded, he explained. There are some requirements for both the images used to obscure files and the files being hidden inside them for his method to work, Buchanan explained. "The cover image must compress well, such that the compressed filesize is less than (width * height) -- size_of_embedded_file," he wrote in his post. "If the cover image does not have a palette, then it must have at least 257 unique colors (otherwise Twitter will optimize it to use a palette)." Resolution on images can be up to 4096 x 4096, although Twitter will serve a downscaled version by default for images greater than 680 x 680 depending on certain factors, Buchanan wrote. The image also should not have any unnecessary "metadata chunks," he added. For embedded files, the total output file size must be less than potentially 5MB, but kept under 3MB to be on the safe side, otherwise Twitter will convert the PNG to a JPEG file, Buchanan explained. Moreover, if the embedded file is a ZIP, then the offsets are automatically adjusted so that the overall file is still a valid ZIP, he said. "For any other file formats, you're on your own," Buchanan added, noting that many will work without special parameters, including PDF and MP3 files.

4,300 Publicly Reachable Servers Are Posing a New DDoS Hazard To the Internet

著者: BeauHD
2021年3月18日 22:00
An anonymous reader quotes a report from Ars Technica: DDoS mitigation provider Netscout said on Wednesday that it has observed DDoS-for-hire services adopting a new amplification vector. The vector is the Datagram Transport Layer Security, or D/TLS, which (as its name suggests) is essentially the Transport Layer Security for UDP data packets. Just as TLS prevents eavesdropping, tampering, or forgery of TLS packets, D/TLS does the same for UDP data. DDoSes that abuse D/TLS allow attackers to amplify their attacks by a factor of 37. Previously, Netscout saw only advanced attackers using dedicated DDoS infrastructure abusing the vector. Now, so-called booter and stressor services -- which use commodity equipment to provide for-hire attacks -- have adopted the technique. The company has identified almost 4,300 publicly reachable D/LTS servers that are susceptible to the abuse. The biggest D/TLS-based attacks Netscout has observed delivered about 45Gbps of traffic. The people responsible for the attack combined it with other amplification vectors to achieve a combined size of about 207Gbps. [...] The 4,300 abusable D/TLS servers are the result of misconfigurations or outdated software that causes an anti-spoofing mechanism to be disabled. While the mechanism is built in to the D/TLS specification, hardware including the Citrix Netscaller Application Delivery Controller didn't always turn it on by default. Citrix has more recently encouraged customers to upgrade to a software version that uses anti-spoofing by default. Besides posing a threat to devices on the Internet at large, abusable D/TLS servers also put organizations using them at risk. Attacks that bounce traffic off one of these machines can create full or partial interruption of mission-critical remote-access services inside the organization's network. Attacks can also cause other service disruptions. Netscout's Hummel and Dobbins said that the attacks can be challenging to mitigate because the size of the payload in a D/TLS request is too big to fit in a single UDP packet and is, therefore, split into an initial and non-initial packet stream.

2021年3月16日 08:20
A lapsed domain registration tied to WeLeakInfo, a wildly popular service that sold access to more than 12 billion usernames and passwords from thousands of hacked websites, "let someone plunder and publish account data on 24,000 customers who paid to access the service with a credit card," reports Krebs on Security. This comes after the service was seized a little over a year ago by the FBI and law enforcement partners overseas. From the report: In a post on the database leaking forum Raidforums, a regular contributor using the handle "pompompurin" said he stole the WeLeakInfo payment logs and other data after noticing the domain wli[.]design was no longer listed as registered. "Long story short: FBI let one of weleakinfo's domains expire that they used for the emails/payments," pompompurin wrote. "I registered that domain, & was able to [password] reset the stripe.com account & get all the Data. [It's] only from people that used stripe.com to checkout. If you used paypal or [bitcoin] ur all good." Cyber threat intelligence firm Flashpoint obtained a copy of the data leaked by pompompurin, and said it includes partial credit card data, email addresses, full names, IP addresses, browser user agent string data, physical addresses, phone numbers, and amount paid. One forum member commented that they found their own payment data in the logs.

Attacks Leveraging Microsoft Exchange Vulnerabilities 'Have Escalated', Doubling Every Three Hours

著者: EditorDavid
2021年3月14日 02:34
Attacks that leverage Microsoft Exchange vulnerabilities "have escalated," warns CNN. They cite a senior White House official saying the window for updating exposed servers is incredibly short -- "measured in hours, not days." On Thursday, Microsoft and security researchers warned that the vulnerabilities are now being combined with another potent cybersecurity threat: ransomware, which locks up a computer or a network's files and holds them hostage until the victim pays a fee. "We have detected and are now blocking a new family of ransomware being used after an initial compromise of unpatched on-premises Exchange Servers," Microsoft said in a tweet. Security experts at Palo Alto Networks estimated Thursday that at least 20,000 US-based Exchange servers remain unpatched and vulnerable to exploitation, and as many as 80,000 around the globe. Other security researchers say the pace of attacks against Exchange servers is rising as opportunistic hackers seek to take advantage of the opening found by Hafnium, the group Microsoft has said is responsible for the original breaches and is "assessed to be state-sponsored and operating out of China." The number of attempted attacks against organizations has been doubling every two to three hours, according to Check Point Research, which monitors the internet for malicious activity.

Swiss authorities raided the apartment Friday of a hacker who claimed credit for breaching the Silicon Valley security camera company Verkada and gaining access to its customers' surveillance feeds, according to the hacker and a search warrant seen by Bloomberg News. From the report: Tillie Kottmann said their apartment in Lucerne, Switzerland, was raided and that police seized the hacker's electronic devices. The warrant was based on an alleged hack that took place last year and not on the recent breach of Verkada. After being notified of the breach by Bloomberg News, Verkada referred the matter to the FBI. The breach exposed live camera feeds of companies like Tesla, as well as hospitals, jails, and schools. According to a copy of the search warrant provided to Bloomberg News, the search was conducted as part of a U.S criminal case against Kottmann in the Western District of Washington. The warrant requested documents related to hacking as well as information on cryptocurrency holdings. Kottmann has been accused of unauthorized access to protected computers, identify theft, and fraud.

2021年3月10日 23:45
The Linux Foundation has announced the launch of Sigstore, a new nonprofit initiative that aims to improve open source software supply chain security by making it easier for developers to adopt cryptographic signing for different components of the software development process. From a report: Sigstore will be free for software providers and developers, who can use it to securely sign software artifacts such as release files, container images, binaries, and bill-of-material manifests. Signing materials are then stored in a tamper-proof public log. The service's code and operation tooling will be fully open source and maintained and developed by the Sigstore community. Founding members include Red Hat, Google, and Purdue University. The idea for the service came from Luke Hinds, security engineering lead in Red Hat's Office of the CTO. He pitched the concept to Google software engineer Dan Lorenc, and the two began to work on it. Now the Sigstore project has a "small but agile community" working on its development, Lorenc says.

How a Malicious Actor Targeted a Go Package On GitHub

2021年3月8日 00:34
ArghBlarg (Slashdot reader #79,067) shares some research from a senior application security engineer at GitLab: Michael Henrikson describes his investigations into Go package manager "supply chain" attacks and found at least one very suspicious package, typosquatting on one of the most popular logging libraries. The imposter package phones home to an IP he alleges belongs to the Chinese company Tencent, a good case for always going over your package imports, in any language, and ensuring you're either a) auditing them regularly, or b) keeping frozen vendored copies which you can trust. From the article: I honestly expected the list to be bigger, but I was of course happy to see that the Go ecosystem isn't completely infested (yet) with malicious typosquat packages... It looks like the author utfave wants to know the hostname, operating system, and architecture of all the machines using their version of urfave/cli. The function extracts the system information and then calls out to the IP address 122.51.124.140 belonging to the Chinese company Shenzhen Tencent Computer Systems via HTTP with the system information added as URL parameters. While this code won't give them any access to systems, it's highly suspicious that they collect this information and the actor can quickly change this code to call back with a reverse shell if they identify a system to be valuable or interesting... I think Go is in a better situation than other programming languages because the source of packages is always explicitly written every time they are used, but code editor automation could make typosquat attacks more likely to happen as the developer doesn't write the import paths manually as often.

At Least 30,000 US Organizations Newly Hacked Via Holes In Microsoft's Email Software

著者: BeauHD
2021年3月6日 09:02
An anonymous reader quotes a report from Krebs On Security: At least 30,000 organizations across the United States -- including a significant number of small businesses, towns, cities and local governments -- have over the past few days been hacked by an unusually aggressive Chinese cyber espionage unit that's focused on stealing email from victim organizations, multiple sources tell KrebsOnSecurity. The espionage group is exploiting four newly-discovered flaws in Microsoft Exchange Server email software, and has seeded hundreds of thousands of victim organizations worldwide with tools that give the attackers total, remote control over affected systems. In each incident, the intruders have left behind a "web shell," an easy-to-use, password-protected hacking tool that can be accessed over the Internet from any browser that gives the attackers administrative access to the victim's computer servers. Speaking on condition of anonymity, two cybersecurity experts who've briefed U.S. national security advisors on the attack told KrebsOnSecurity the Chinese hacking group thought to be responsible has seized control over "hundreds of thousands" of Microsoft Exchange Servers worldwide -- with each victim system representing approximately one organization that uses Exchange to process email. Microsoft said the Exchange flaws are being targeted by a previously unidentified Chinese hacking crew it dubbed "Hafnium," and said the group had been conducting targeted attacks on email systems used by a range of industry sectors, including infectious disease researchers, law firms, higher education institutions, defense contractors, policy think tanks, and NGOs. Microsoft's initial advisory about the Exchange flaws credited Reston, Va. based Volexity for reporting the vulnerabilities. "We've worked on dozens of cases so far where web shells were put on the victim system back on Feb. 28 [before Microsoft announced its patches], all the way up to today," Volexity President Steven Adair said. "Even if you patched the same day Microsoft published its patches, there's still a high chance there is a web shell on your server. The truth is, if you're running Exchange and you haven't patched this yet, there's a very high chance that your organization is already compromised." A Microsoft spokesperson said in a statement: "The best protection is to apply updates as soon as possible across all impacted systems. We continue to help customers by providing additional investigation and mitigation guidance. Impacted customers should contact our support teams for additional help and resources."

Three Top Russian Cybercrime Forums Hacked

2021年3月5日 05:05
tsu doh nimh shares a report: Over the past few weeks, three of the longest running and most venerated Russian-language online forums serving thousands of experienced cybercriminals have been hacked. In two of the intrusions, the attackers made off with the forums' user databases, including email and Internet addresses and hashed passwords. Members of all three forums are worried the incidents could serve as a virtual Rosetta Stone for connecting the real-life identities of the same users across multiple crime forums. On Tuesday, someone dumped thousands of usernames, email addresses and obfuscated passwords on the dark web apparently pilfered from Mazafaka (a.k.a. "Maza," "MFclub"), an exclusive crime forum that has for more than a decade played host to some of the most experienced and infamous Russian cyberthieves. At the top of a 35-page PDF leaked online is a private encryption key allegedly used by Maza administrators. The database also includes ICQ numbers for many users. ICQ, also known as "I seek you," was an instant message platform trusted by countless early denizens of these older crime forums before its use fell out of fashion in favor of more private networks, such as Jabber and Telegram. This is notable because ICQ numbers tied to specific accounts often are a reliable data point that security researchers can use to connect multiple accounts to the same user across many forums and different nicknames over time. Cyber intelligence firm Intel 471 assesses that the leaked Maza database is legitimate.

US Issues Warning After Microsoft Says China Hacked Its Mail Server Program

著者: BeauHD
2021年3月4日 12:30
An anonymous reader quotes a report from NBC News: The U.S. has issued an emergency warning after Microsoft said it caught China hacking into its mail and calendar server program, called Exchange. The perpetrator, Microsoft said in a blog post, is a hacker group that the company has "high confidence" is working for the Chinese government and primarily spies on American targets. The latest software update for Exchange blocks the hackers, prompting the U.S. Cybersecurity and Infrastructure Security Agency to issue a rare emergency directive that requires all government networks do so. CISA, the U.S.'s primary defensive cybersecurity agency, rarely exercises its authority to demand the entire U.S. government take protective steps to protect its cybersecurity. The move was necessary, the agency announced, because the Exchange hackers are able "to gain persistent system access." All government agencies have until noon Friday to download the latest software update. In a separate blog post, Microsoft Vice President Tom Burt wrote that the hackers have recently spied on a wide range of American targets, including disease researchers, law firms and defense contractors. There was no immediate indication that the hack led to significant exploitation of U.S. government computer networks. But the announcement marks the second instance in recent months that the U.S. scrambled to address a widespread hacking campaign believed be the work of foreign government spies.

Far-Right Platform Gab Has Been Hacked

著者: BeauHD
2021年3月2日 08:20
The far-right social media platform Gab says a trove of its contents has been stolen in a security breach -- including passwords and private communications. Wired reports: On Sunday night the WikiLeaks-style group Distributed Denial of Secrets is revealing what it calls GabLeaks, a collection of more than 70 gigabytes of Gab data representing more than 40 million posts. DDoSecrets says a hacktivist who self-identifies as "JaXpArO and My Little Anonymous Revival Project" siphoned that data out of Gab's backend databases in an effort to expose the platform's largely right-wing users. Those Gab patrons, whose numbers have swelled after Parler went offline, include large numbers of Qanon conspiracy theorists, white nationalists, and promoters of former president Donald Trump's election-stealing conspiracies that resulted in the January 6 riot on Capitol Hill. DDoSecrets cofounder Emma Best says that the hacked data includes not only all of Gab's public posts and profiles -- with the exception of any photos or videos uploaded to the site -- but also private group and private individual account posts and messages, as well as user passwords and group passwords. "It contains pretty much everything on Gab, including user data and private posts, everything someone needs to run a nearly complete analysis on Gab users and content," Best wrote in a text message interview with WIRED. "It's another gold mine of research for people looking at militias, neo-Nazis, the far right, QAnon, and everything surrounding January 6." DDoSecrets says it's not publicly releasing the data due to its sensitivity and the vast amounts of private information it contains. Instead the group says it will selectively share it with journalists, social scientists, and researchers. According to DDoSecrets' Best, the hacker says that they pulled out Gab's data via a SQL injection vulnerability in the siteâ"a common web bug in which a text field on a site doesn't differentiate between a user's input and commands in the site's code, allowing a hacker to reach in and meddle with its backend SQL database. Despite the hacker's reference to an "Anonymous Revival Project," they're not associated with the loose hacker collective Anonymous, they told Best, but do "want to represent the nameless struggling masses against capitalists and fascists." The company's CEO, Andrew Torba, responded in a public statement on the company's blog that "reporters, who write for a publication that has written many hit pieces on Gab in the past, are in direct contact with the hacker and are essentially assisting the hacker in his efforts to smear our business and hurt you, our users."

First Fully Weaponized Spectre Exploit Discovered Online

著者: msmash
2021年3月2日 03:41
Catalin Cimpanu, reporting for The Record: A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered by French security researcher Julien Voisin. It targets Spectre, a major vulnerability that was disclosed in January 2018. [...] The vulnerability, which won a Pwnie Award in 2018 for one of the best security bug discoveries of the year, was considered a milestone moment in the evolution and history of the modern CPU. Its discovery, along with the Meltdown bug, effectively forced CPU vendors to rethink their approach to designing processors, making it clear that they cannot focus on performance alone, to the detriment of data security. Software patches were released at the time, but the Meltdown and Spectre disclosures forced Intel to rethink its entire approach to CPU designs going forward. At the time, the teams behind the Meltdown and Spectre bugs published their work in the form of research papers and some trivial proof-of-concept code to prove their attacks. Shortly after the Meltdown and Spectre publications, experts at AV-TEST, Fortinet, and Minerva Labs spotted a spike in VirusTotal uploads for both CPU bugs. While initially there was a fear that malware authors might be experimenting with the two bugs as a way to steal data from targeted systems, the exploits were classified as harmless variations of the public PoC code published by the Meltdown and Spectre researchers and no evidence was found of in-the-wild attacks. But today, Voisin said he discovered new Spectre exploits -- one for Windows and one for Linux -- different from the ones before. In particular, Voisin said he found a Linux Spectre exploit capable of dumping the contents of /etc/shadow, a Linux file that stores details on OS user accounts.

Go Malware is Now Common, Having Been Adopted by Both APTs and E-crime Groups

2021年3月2日 00:45
The number of malware strains coded in the Go programming language has seen a sharp increase of around 2,000% over the last few years, since 2017, cybersecurity firm Intezer said in a report published recently. From a report: The company's findings highlight and confirm a general trend in the malware ecosystem, where malware authors have slowly moved away from C and C++ to Go, a programming language developed and launched by Google in 2007. While the first Go-based malware was detected in 2012, it took, however, a few years for Golang to catch on with the malware scene. "Before 2019, spotting malware written in Go was more a rare occurrence and during 2019 it became a daily occurrence," Intezer said in its report. But in the new report, Golang (as it's often also referred to instead of Go) has broken through and has been widely adopted. It is used by nation-state hacking groups (also known as APTs), cybercrime operators, and even security teams alike, who often used it to create penetration-testing toolkits.

Flaws In Zoom's Keybase App Kept Chat Images From Being Deleted

著者: EditorDavid
2021年3月1日 01:34
chicksdaddy writes: The Security Ledger reports that a flaw in Zoom's Keybase secure chat application left copies of images contained in secure communications on Keybase users' computers after they were supposedly deleted, according to researchers from the security research group Sakura Samurai. The flaw in the encrypted messaging application, CVE-2021-23827 does not expose Keybase users to remote compromise. However, it could put their security, privacy and safety at risk, especially for users living under authoritarian regimes in which apps like Keybase and Signal are increasingly relied on as a way to conduct conversations out of earshot of law enforcement or security services. It comes as millions of users have flocked to apps like Keybase, Signal and Telegram in recent months. Sakura Samurai researchers Aubrey Cottle, Robert Willis, and Jackson Henry discovered an unencrypted directory, /Cache, associated with the Keybase client that contained a comprehensive record of images from encrypted chat sessions. The application used a custom extension to name the files, but they were easily viewable directly or simply by changing the custom file extension to the PNG image format, researcher John Jackson told Security Ledger. In a statement, a Zoom spokesman said that the company appreciates the work of the researchers and takes privacy and security "very seriously." "We addressed the issue identified by the Sakura Samurai researchers on our Keybase platform in version 5.6.0 for Windows and macOS and version 5.6.1 for Linux. Users can help keep themselves secure by applying current updates or downloading the latest Keybase software with all current security updates," the spokesman said. In most cases, the failure to remove files from cache after they were deleted would count as a "low priority" security flaw. However, in the context of an end-to-end encrypted communications application like Keybase, the failure takes on added weight, Jackson wrote.

Introducing Crowdsec: a Modernized, Collaborative Massively Multiplayer Firewall

2021年3月1日 00:34
Slashdot reader b-dayyy writes: CrowdSec is a massively multiplayer firewall designed to protect Linux servers, services, containers, or virtual machines exposed on the Internet with a server-side agent. It was inspired by Fail2Ban and aims to be a modernized, collaborative version of that intrusion-prevention tool. CrowdSec is free and open-source (under an MIT License), with the source code available on GitHub. It uses a behavior analysis system to qualify whether someone is trying to hack you, based on your logs. If your agent detects such aggression, the offending IP is then dealt with and sent for curation. If this signal passes the curation process, the IP is then redistributed to all users sharing a similar technological profile to 'immunize' them against this IP. The goal is to leverage the power of the crowd to create a real-time IP reputation database. As for the IP that aggressed your machine, you can choose to remedy the threat in any manner you feel appropriate. Ultimately, CrowdSec leverages the power of the community to create an extremely accurate IP reputation system that benefits all its users. It was clear to the founders that Open Source was going to be one of the main pillars of CrowdSec. The project's founders have been working on open-source projects for decades — they didn't just jump on the train. Rather, they are strong Open Source believers. They believe that the crowd is key to the mass hacking plague we are experiencing, and that Open Source is the best lever to create a community and have people contribute their knowledge to the project, ultimately make it better and more secure. The solution recently turned 1.x, introducing a major architectural change: the introduction of a local REST API.

Jamaica's JamCOVID Pulled Offline After Third Security Lapse Exposed Travelers' Data

2021年2月27日 21:00
Jamaica's JamCOVID app and website were taken offline late on Thursday following a third security lapse, which exposed quarantine orders on more than half a million travelers to the island. From a report: JamCOVID was set up last year to help the government process travelers arriving on the island. Quarantine orders are issued by the Jamaican Ministry of Health and instruct travelers to stay in their accommodation for two weeks to prevent the spread of COVID-19. These orders contain the traveler's name and the address of where they are ordered to stay. But a security researcher told TechCrunch that the quarantine orders were publicly accessible from the JamCOVID website but were not protected with a password. Although the files were accessible from anyone's web browser, the researcher asked not to be named for fear of legal repercussions from the Jamaican government. More than 500,000 quarantine orders were exposed, some dating back to March 2020. TechCrunch shared these details with the Jamaica Gleaner, which was first to report on the security lapse after the news outlet verified the data spillage with local cybersecurity experts. Amber Group, which was contracted to build and maintain the JamCOVID coronavirus dashboard and immigration service, pulled the service offline a short time after TechCrunch and the Jamaica Gleaner contacted the company on Thursday evening. JamCOVID's website was replaced with a holding page that said the site was "under maintenance." At the time of publication, the site had returned.

CD Projekt SA said Wednesday it will delay a promised update to the much-criticized role-playing game Cyberpunk 2077, pinning the blame for its slow progress on a recent security breach. From a report: What the Polish publisher didn't say is that most of its employees have been locked out of their workstations for the past two weeks, according to people familiar with the matter. The work stoppage is the result of a ransomware attack disclosed on Feb. 9. The extent of the disruption, which hasn't been previously reported, poses a major setback to CD Projekt's attempt to rescue a game in desperate need of repairs. CD Projekt has said it refused to pay a ransom to the hackers. As a result, employees remain unable to log onto the company's virtual private network, making it impossible to access the systems and tools needed to do most of their jobs, said the people, requesting anonymity because they weren't authorized to talk publicly. Although some CD Projekt employees are working from the headquarters in Warsaw, the majority are at home due to the coronavirus pandemic.
