Jerry Rivers shares a report from TechCrunch, adding: "...and it took the music service seven months to notice." From the report: In a data breach notification filed with the California attorney general's office, the music streaming giant said the data exposed "may have included email address, your preferred display name, password, gender, and date of birth only to certain business partners of Spotify." The company did not name the business partners, but added that Spotify "did not make this information publicly accessible." The company says the vulnerability existed as far back as April 9 but wasn't discovered until November 12. It didn't say what the vulnerability was or how user account data became exposed. "We have conducted an internal investigation and have contacted all of our business partners that may have had access to your account information to ensure that any personal information that may have been inadvertently disclosed to them has been deleted," the letter read.

FireEye, a Top Cybersecurity Firm, Says It Was Hacked By a Nation-State

2020年12月9日 07:50
An anonymous reader quotes a report from The New York Times : For years, the cybersecurity firm FireEye has been the first call for government agencies and companies around the world who have been hacked by the most sophisticated attackers, or fear they might be. Now it looks like the hackers -- in this case, evidence points to Russia's intelligence agencies -- may be exacting their revenge. FireEye revealed on Tuesday that its own systems were pierced by what it called "a nation with top-tier offensive capabilities." The company said hackers used "novel techniques" to make off with its own tool kit, which could be useful in mounting new attacks around the world. It was a stunning theft, akin to bank robbers who, having cleaned out local vaults, then turned around and stole the F.B.I.'s investigative tools. In fact, FireEye said on Tuesday, moments after the stock market closed, that it had called in the F.B.I. The $3.5 billion company, which partly makes a living by identifying the culprits in some of the world's boldest breaches -- its clients have included Sony and Equifax -- declined to say explicitly who was responsible. But its description, and the fact that the F.B.I. has turned the case over to its Russia specialists, left little doubt who the lead suspects were and that they were after what the company calls "Red Team tools." These are essentially digital tools that replicate the most sophisticated hacking tools in the world. FireEye uses the tools — with the permission of a client company or government agency -- to look for vulnerabilities in their systems. Most of the tools are based in a digital vault that FireEye closely guards. The hack raises the possibility that Russian intelligence agencies saw an advantage in mounting the attack while American attention -- including FireEye's -- was focused on securing the presidential election system. At a moment that the nation's public and private intelligence systems were seeking out breaches of voter registration systems or voting machines, it may have a been a good time for those Russian agencies, which were involved in the 2016 election breaches, to turn their sights on other targets. The hack was the biggest known theft of cybersecurity tools since those of the National Security Agency were purloined in 2016 by a still-unidentified group that calls itself theShadowBrokers. [...] The N.S.A.'s tools were most likely more useful than FireEye's since the U.S. government builds purpose-made digital weapons. FireEye's Red Team tools are essentially built from malware that the company has seen used in a wide range of attacks. Still, the advantage of using stolen weapons is that nation-states can hide their own tracks when they launch attacks.

GE Puts Default Password In Radiology Devices, Leaving Healthcare Networks Exposed

著者: BeauHD
2020年12月9日 05:50
An anonymous reader quotes a report from Ars Technica: Dozens of radiology products from GE Healthcare contain a critical vulnerability that threatens the networks of hospitals and other health providers that use the devices, officials from the US government and a private security firm said on Tuesday. The devices -- used for CT scans, MRIs, X-Rays, mammograms, ultrasounds, and positron emission tomography -- use a default password to receive regular maintenance. The passwords are available to anyone who knows where on the Internet to look. A lack of proper access restrictions allows the devices to connect to malicious servers rather than only those designated by GE Healthcare. Attackers can exploit these shortcomings by abusing the maintenance protocols to access the devices. From there, the attackers can execute malicious code or view or modify patient data stored on the device or the hospital or healthcare provider servers. Aggravating matters, customers can't fix the vulnerability themselves. Instead, they must request that the GE Healthcare support team change the credentials. Customers who don't make such a request will continue to rely on the default password. Eventually, the device manufacturer will provide patches and additional information. The flaw has a CVSS severity rating of 9.8 out of 10 because of the impact of the vulnerability combined with the ease of exploiting it. Security firm CyberMDX discovered the vulnerability and privately reported it to the manufacturer in May. The US Cyber Security and Infrastructure Security Agency is advising affected healthcare providers to take mitigation steps as soon as possible. In a statement, GE Healthcare officials wrote: "We are not aware of any unauthorized access to data or incident where this potential vulnerability has been exploited in a clinical situation. We have conducted a full risk assessment and concluded that there is no patient safety concern. Maintaining the safety, quality, and security of our devices is our highest priority. We are providing on-site assistance to ensure credentials are changed properly and confirm proper configuration of the product firewall. Additionally, we are advising the facilities where these devices are located to follow network management and security best practices."

FriendlySolipsist writes: Independent journalist Rebekah Jones, a scientist fired by the Florida state government because, she said, of her refusal to manipulate official COVID-19 data releases to coincide with political considerations and who now operates website floridacovidaction.com, had her home raided by the FL state police who seized computers and cellphones, the Miami Herald reported. The FDLE affidavit in support of the raid was published by the Miami Herald and asserts that an unauthorized internal message was sent to the "ReadyOps" system within the state Department of Health from an IPv6 address associated with the Comcast account at Jones residence. "The Florida Department of Law Enforcement on Monday raided the home of a former Department of Health data analyst who has been running an alternative web site to the state's COVID dashboard, alleging that she may have broken into a state email system and sent an unauthorized message to employees," reports the Miami Herald. "But Rebekah Jones, who was was fired from her job in May as the geographic information system manager for DOH's Division of Disease Control and Health Protection and who has since filed a whistleblower complaint against the state, denied having any role in the alleged intrusion into the state web site and instead said she believes Monday's action was intended to silence her."

2020年12月8日 09:10
A mysterious hacker sed a cyber-attack to force-open the doors of 2,732 package delivery lockers across Moscow. ZDNet reports: The attack, which took place on Friday afternoon, December 4, targeted the network of PickPoint, a local delivery service that maintains a network of more than 8,000 package lockers across Moscow and Saint Petersburg. Russians can order products online and choose to have any of their orders delivered to a PickPoint locker instead of their home address. Once the package arrives, users receive an email or mobile notification, and they can show up and pick up their orders using the PickPoint app. However, the same system that allows users to open lockers and retrieve their packages was attacked on Friday. Using a yet-to-be-identified exploit, a mysterious hacker forced open the doors for a third of PickPoint's lockers, leaving thousands of packages exposed to theft across Moscow. The reason for the attack has yet to be discovered, but in press releases over the weekend, PickPoint said it notified authorities. The Russian company said it is currently working to restore its network, which has been damaged during the attack. It also remains unclear if packages were stolen from lockers. As the company highlighted in a press release on Saturday, this appears to be "the world's first targeted cyberattack against a post-gateway network."

PC maker powerhouse Dell announced today a flurry of new enterprise security solutions for the company's line of enterprise products. From a report: The new services can be grouped into two categories, with (1) new solutions meant to protect the supply chain of Dell products while in transit to their customers and (2) new features meant to improve the security of Dell products while in use. While Dell has previously invested in securing its customers' supply chains, the company has announced today three new services. The first is named SafeSupply Chain Tamper Evident Services and, as its name implies, involves Dell adding anti-tampering seals to its devices, transport boxes, and even entire pallets before they leave Dell factories. The anti-tampering seals will allow buyers of Dell equipment to determine if any intermediary agents or transporters have opened boxes or devices to alter physical components. The second supply chain security offering, named the Dell SafeSupply Chain Data Sanitization Services, is meant for tampering made at the storage level.

IBM's cyber-security division says that hackers are targeting companies associated with the storage and transportation of COVID-19 vaccines using temperature-controlled environments -- also known as the COVID-19 vaccine cold chain. From a report: The attacks consisted of spear-phishing emails seeking to collect credentials for a target's internal email and applications. While IBM X-Force analysts weren't able to link the attacks to a particular threat actor, they said the phishing campaign showed the typical "hallmarks of nation-state tradecraft." Targets of the attacks included a wide variety of companies, sectors, and government organizations alike.

FBI Warns of Email Forwarding Rules Being Abused in Recent Hacks

著者: msmash
2020年12月3日 06:30
The US Federal Bureau of Investigation says that cyber-criminals are increasingly relying on email forwarding rules in order to disguise their presence inside hacked email accounts. From a report: In a PIN (Private Industry Notification) alert sent last week and made public today, the FBI says the technique has been seen and abused in recent BEC (Business Email Compromise) attacks reported over the summer. The hackers' technique relies on a feature found in some email services called "auto-forwarding email rules." As its name implies, the feature allows the owner of an email address to set up "rules" that forward (redirect) an incoming email to another address if a certain criteria is met. Threat actors absolutely love email auto-forwarding rules as they allow them to receive copies of all incoming emails without having to log into an account each day -- and be at risk of triggering a security warning for a suspicious login.

Malicious npm Packages Caught Installing Remote Access Trojans

著者: msmash
2020年12月3日 05:10
The security team behind the "npm" repository for JavaScript libraries removed two npm packages this Monday for containing malicious code that installed a remote access trojan (RAT) on the computers of developers working on JavaScript projects. From a report: The name of the two packages was jdb.js and db-json.js., and both were created by the same author and described themselves as tools to help developers work with JSON files typically generated by database applications. Both packages were uploaded on the npm package registry last week and were downloaded more than 100 times before their malicious behavior was detected by Sonatype, a company that scans package repositories on a regular basis. According to Sonatype's Ax Sharma, the two packages contained a malicious script that executed after web developers imported and installed any of the two malicious libraries. The post-install script performed basic reconnaissance of the infected host and then attempted to download and run a file named patch.exe that later installed njRAT, also known as Bladabindi, a very popular remote access trojan that has been used in espionage and data theft operations since 2015.

iPhone Zero-Click Wi-Fi Exploit is One of the Most Breathtaking Hacks Ever

著者: msmash
2020年12月3日 04:33
Dan Goodin, writing for ArsTechnica: Earlier this year, Apple patched one of the most breathtaking iPhone vulnerabilities ever: a memory corruption bug in the iOS kernel that gave attackers remote access to the entire device -- over Wi-Fi, with no user interaction required at all. Oh, and exploits were wormable -- meaning radio-proximity exploits could spread from one nearby device to another, once again, with no user interaction needed. This Wi-Fi packet of death exploit was devised by Ian Beer, a researcher at Project Zero, Google's vulnerability research arm. In a 30,000-word post published on Tuesday afternoon, Beer described the vulnerability and the proof-of-concept exploit he spent six months developing single-handedly. Almost immediately, fellow security researchers took notice. "This is a fantastic piece of work," Chris Evans, a semi-retired security researcher and executive and the founder of Project Zero, said in an interview. "It really is pretty serious. The fact you don't have to really interact with your phone for this to be set off on you is really quite scary. This attack is just you're walking along, the phone is in your pocket, and over Wi-Fi someone just worms in with some dodgy Wi-Fi packets." Beer's attack worked by exploiting a buffer overflow bug in a driver for AWDL, an Apple-proprietary mesh networking protocol that makes things like Airdrop work. Because drivers reside in the kernel -- one of the most privileged parts of any operating system -- the AWDL flaw had the potential for serious hacks. And because AWDL parses Wi-Fi packets, exploits can be transmitted over the air, with no indication that anything is amiss.

Companies Urged To Adjust Hiring Requirements for Cyber Jobs

2020年12月2日 00:32
Companies need millions more cybersecurity professionals to fill roles around the world, but researchers say outlandish job requirements are the problem, rather than a lack of workers. From a report: Around 3.1 million professionals are needed to bridge the cybersecurity talent gap, a trade association for cybersecurity professionals estimated in a November report. The International Information System Security Certification Consortium, known as ISC2, said world-wide employment in the field would need to grow 89% to meet security requirements. However, excessive requirements for years of experience and professional certifications plus inflated expectations for junior roles aren't uncommon, said Chase Cunningham, principal analyst at research firm Forrester. He said that results in the perpetual problem of such positions going unfilled because companies often target overqualified candidates who can command greater salaries than these jobs tend to offer.

Patients of a Vermont Hospital Are Left 'in the Dark' After a Cyberattack

著者: msmash
2020年11月27日 18:01
A wave of damaging attacks on hospitals upended the lives of patients with cancer and other ailments. From a report: At lunchtime on Oct. 28, Colleen Cargill was in the cancer center at the University of Vermont Medical Center, preparing patients for their chemotherapy infusions. A new patient will sometimes be teary and frightened, but the nurses try to make it welcoming, offering trail mix and a warm blanket, a seat with a view of a garden. Then they work with extreme precision: checking platelet and white blood cell counts, measuring each dosage to a milligram per square foot of body area, before settling the person into a port and hooking them up to an IV. That day, though, Ms. Cargill did a double-take: When she tried to log in to her work station, it booted her out. Then it happened again. She turned to the system of pneumatic tubes used to transport lab work. What she saw there was a red caution symbol, a circle with a cross. She walked to the backup computer. It was down, too. "I wasn't panicky," she said, "and then I noticed my cordless phone didn't work." That was, she said, the beginning of the worst 10 days of her career. Cyberattacks on America's health systems have become their own kind of pandemic over the past year as Russian cybercriminals have shut down clinical trials and treatment studies for the coronavirus vaccine and cut off hospitals' access to patient records, demanding multimillion-dollar ransoms for their return. Complicating the response, President Trump last week fired Christopher Krebs, the director of CISA, the cybersecurity agency responsible for defending critical systems, including hospitals and elections, against cyberattacks, after Mr. Krebs disputed Mr. Trump's baseless claims of voter fraud. The attacks have largely unfolded in private, as hospitals scramble to restore their systems -- or to quietly pay the ransom -- without releasing information that could compromise an F.B.I. investigation. [...] The latest wave of attacks, which hit about a dozen hospitals in the United States, was believed to have been conducted by a particularly powerful group of Russian-speaking hackers that deployed ransomware via TrickBot, a vast network of infected computers used for cyberattacks, according to security researchers who are tracking the attacks.

U.S. Fertility, one of the largest networks of fertility clinics in the United States, has confirmed it was hit by a ransomware attack and that data was taken. From a report: The company was formed in May as a partnership between Shady Grove Fertility, a fertility clinic with dozens of locations across the U.S. east coast, and Amulet Capital Partners, a private equity firm that invests largely in the healthcare space. As a joint venture, U.S. Fertility now claims 55 locations across the U.S., including California. In a statement, U.S. Fertility said that the hackers "acquired a limited number of files" during the month that they were in its systems, until the ransomware was triggered on September 14. That's a common technique of data-stealing ransomware, which steals data before encrypting the victim's network for ransom. Some ransomware groups publish the stolen files on their websites if their ransom demand isn't paid. U.S. Fertility said some personal information, like names and addresses, were taken in the attack. Some patients also had their Social Security numbers taken. But the company warned that the attack may have involved protected health information.

hCaptcha Runs On 15% Of the Internet

著者: BeauHD
2020年11月26日 19:00
In a blog post, hCaptcha announced that its bot detector is running on about 15% of the internet, adding they they "took most of this market share directly from Google reCAPTCHA." From the post: Competing with Google and other Big Tech companies seems like a tall order: their monopolistic market power, platform effects and army of highly paid developers are generally considered too powerful to tackle for anyone but other tech giants such as Facebook or Amazon. Our story shows that it doesn't have to be that way -- you can beat Big Tech by focussing on privacy. Consider Google reCAPTCHA, which consumes enormous amounts of behavioral data to determine whether web users are legitimate humans or bots. At hCaptcha, we have deliberately taken a very different approach, using privacy-preserving machine learning techniques to identify typical bot behaviors at high accuracy, all while consuming and storing as little data as possible. Google is an ad company, and their security products look very much like their ad products: they track user behavior on every page of a website and across the web. We designed hCaptcha to be as privacy-friendly as possible from day one. This led to a completely different approach to the problem. As it turns out, tracking users across the web and tying their web history to their identity is completely unnecessary for achieving good security. The many companies that have switched over to hCaptcha often report equal or better performance in bot detection and mitigation despite our privacy focus. A growing number of critics have pointed out that Google's disregard for user privacy should concern customers looking to protect their websites and apps. At the same time, stopping bots from accessing publisher sites can reveal ad fraud, pitting Google's reCAPTCHA product directly against their ad business, which produces over 80% of their revenue. Every bot Google detects should be earning zero ad dollars. Google's company incentives are thus poorly aligned with the users of their security services, and this may be one explanation for the poor performance of their reCAPTCHA security offering.

2FA Bypass Discovered In Web Hosting Software cPanel

著者: BeauHD
2020年11月26日 07:28
An anonymous reader quotes a report from ZDNet: Security researchers have discovered a major security flaw in cPanel, a popular software suite used by web hosting companies to manage websites for their customers. The bug, discovered by security researchers from Digital Defense, allows attackers to bypass two-factor authentication (2FA) for cPanel accounts. These accounts are used by website owners to access and manage their websites and underlying server settings. Access to these accounts is critical, as once compromised, they grant threat actors full control over a victim's site. On its website, cPanel boasts that its software is currently used by hundreds of web hosting companies to manage more than 70 million domains across the world. But in a press release today, Digital Defense says that the 2FA implementation on older cPanel & WebHost Manager (WHM) software was vulnerable to brute-force attacks that allowed threat actors to guess URL parameters and bypass 2FA -- if 2FA was enabled for an account. While brute-forcing attacks, in general, usually take hours or days to execute, in this particular case, the attack required only a few minutes, Digital Defense said today. Exploiting this bug also requires that attackers have valid credentials for a targeted account, but these can be obtained from phishing the website owner. The good news is that Digital Defense has privately reported the bug, tracked as SEC-575, to the cPanel team, which has already released patches last week.

'Smart' Doorbells For Sale On Amazon, eBay Came Stocked With Security Vulnerabilities

著者: BeauHD
2020年11月24日 11:02
The U.K.-based security company NCC Group and consumer advocacy group Which? have found vulnerabilities in 11 "smart" doorbells sold on popular platforms like Amazon and eBay. CyberScoop reports: One flaw could allow a remote attacker to break into the wireless network by swiping login credentials. Another critical bug, which has been around for years, could enable attackers to intercept and manipulate data on the network. The investigation focused on doorbells made by often obscure vendors, but which nonetheless earned top reviews and featured prominently on Amazon and eBay. The researchers raised concerns that some of the devices were storing sensitive data, including location data and audio and video captured by the doorbell's camera, on insecure servers. One device made by a company called Victure, for example, sent a user's wireless name and password, unencrypted, to servers in China, according to the researchers. In a statement, Amazon said it requires products sold on its site to be compliant with applicable laws and regulations, and that it has tools to detect "unsafe or non-compliant products from being listed in our stores." eBay said it takes down listings that violate its safety standards, but that the devices flagged by the researchers did not meet that threshold. Victure did not immediately respond to a request for comment. The NCC Group-Which? team said they tried to contact the various vendors of the vulnerable smart doorbells, with mixed success. The unnamed vendor of one device, for example, removed an online listing for the product after the researchers shared their findings.

Walmart-exclusive Router and Others Sold on Amazon and eBay Contain Hidden Backdoors To Control Devices

著者: msmash
2020年11月24日 04:26
Bernard Meyer, reporting for CyberNews: In a collaboration between CyberNews Sr. Information Security Researcher Mantas Sasnauskas and researchers James Clee and Roni Carta, suspicious backdoors have been discovered in a Chinese-made Jetstream router, sold exclusively at Walmart as their new line of "affordable" wifi routers. This backdoor would allow an attacker the ability to remotely control not only the routers, but also any devices connected to that network. CyberNews reached out to Walmart for comment and to understand whether they were aware of the Jetstream backdoor, and what they plan to do to protect their customers. After we sent information about the affected Jetstream device, a Walmart spokesperson informed CyberNews: "Thank you for bringing this to our attention. We are looking into the issue to learn more. The item in question is currently out of stock and we do not have plans to replenish it." Besides the Walmart-exclusive Jetstream router, the cybersecurity research team also discovered that low-cost Wavlink routers, normally sold on Amazon or eBay, have similar backdoors. The Wavlink routers also contain a script that lists nearby wifi and has the capability to connect to those networks. We have also found evidence that these backdoors are being actively exploited, and there's been an attempt to add the devices to a Mirai botnet. Mirai is malware that infects devices connected to a network, turns them into remotely controlled bots as part of a botnet, and uses them in large-scale attacks. The most famous of these is the 2016 Dyn DNS cyberattack, which brought down major websites like Reddit, Netflix, CNN, GitHub, Twitter, Airbnb and more.

LidarPhone Attack Converts Smart Vacuums Into Microphones

著者: BeauHD
2020年11月20日 09:10
An anonymous reader quotes a report from ZDNet: A team of academics has detailed this week novel research that converted a smart vacuum cleaner into a microphone capable of recording nearby conversations. Named LidarPhone, the technique works by taking the vacuum's built-in LiDAR laser-based navigational component and converting it into a laser microphone. [...] They tested the LidarPhone attack with various objects, by varying the distance between the robot and the object, and the distance between the sound origin and the object. Tests focused on recovering numerical values, which the research team said they managed to recover with a 90% accuracy. But academics said the technique could also be used to identify speakers based on gender or even determine their political orientation from the music played during news shows, captured by the vacuum's LiDAR. But while the LidarPhone attack sounds like a gross invasion of privacy, users need not panic for the time being. This type of attack revolves around many prerequisites that most attacks won't bother. There are far easier ways of spying on users than overwriting a vacuum's firmware to control its laser navigation system, such as tricking the user on installing malware on their phone. The LidarPhone attack is merely novel academic research that can be used to bolster the security and design of future smart vacuum robots. In fact, the research team's main recommended countermeasure for smart vacuum cleaning robot makers is to shut down the LiDAR component if it's not rotating. Additional details about the research are available in a research paper titled "Spying with Your Robot Vacuum Cleaner: Eavesdropping via Lidar Sensors."

Massive, China-State-Funded Hack Hits Companies Around the World, Report Says

著者: BeauHD
2020年11月19日 12:30
An anonymous reader quotes a report from Ars Technica: Researchers have uncovered a massive hacking campaign that's using sophisticated tools and techniques to compromise the networks of companies around the world. The hackers, most likely from a well-known group that's funded by the Chinese government, are outfitted with both off-the-shelf and custom-made tools. One such tool exploits Zerologon, the name given to a Windows server vulnerability, patched in August, that can give attackers instant administrator privileges on vulnerable systems. Symantec uses the code name Cicada for the group, which is widely believed to be funded by the Chinese government and also carries the monikers of APT10, Stone Panda, and Cloud Hopper from other research organizations. The group has been active in espionage-style hacking since at least 2009 and almost exclusively targets companies linked to Japan. While the companies targeted in the recent campaign are located in the United States and other countries, all of them have links to Japan or Japanese companies. The attacks make extensive use of DLL side-loading, a technique that occurs when attackers replace a legitimate Windows dynamic-link library file with a malicious one. Attackers use DLL side-loading to inject malware into legitimate processes so they can keep the hack from being detected by security software. The campaign also makes use of a tool that's capable of exploiting Zerologon. Exploits work by sending a string of zeros in a series of messages that use the Netlogon protocol, which Windows servers use to let users log into networks. People with no authentication can use Zerologon to access an organization's crown jewels -- the Active Directory domain controllers that act as an all-powerful gatekeeper for all machines connected to a network. Microsoft patched the critical privilege-escalation vulnerability in August, but since then attackers have been using it to compromise organizations that have yet to install the update. Both the FBI and Department of Homeland Security have urged that systems be patched immediately. Among the machines compromised during attacks discovered by Symantec were domain controllers and file servers. Company researchers also uncovered evidence of files being exfiltrated from some of the compromised machines.
