'Google App Engine' Abused to Create Unlimited Phishing Pages

著者: EditorDavid
2020年9月27日 23:34
Google's cloud-based service platform for developing and hosting web apps "can be abused to deliver phishing and malware while remaining undetected by leading enterprise security products," reports Bleeping Computer, citing a startling discovery by security researcher Marcel Afrahim: A Google App Engine subdomain does not only represent an app, it represents an app's version, the service name, project ID, and region ID fields. But the most important point to note here is, if any of those fields are incorrect, Google App Engine won't show a 404 Not Found page, but instead show the app's "default" page (a concept referred to as soft routing)... Essentially, this means there are a lot of permutations of subdomains to get to the attacker's malicious app. As long as every subdomain has a valid "project_ID" field, invalid variations of other fields can be used at the attacker's discretion to generate a long list of subdomains, which all lead to the same app... The fact that a single malicious app is now represented by multiple permutations of its subdomains makes it hard for sysadmins and security professionals to block malicious activity. But further, to a technologically unsavvy user, all of these subdomains would appear to be a "secure site." After all, the appspot.com domain and all its subdomains come with the seal of "Google Trust Services" in their SSL certificates. Even further, most enterprise security solutions such as Symantec WebPulse web filter automatically allow traffic to trusted category sites. And Google's appspot.com domain, due to its reputation and legitimate corporate use cases, earns an "Office/Business Applications" tag, skipping the scrutiny of web proxies.

Ring's latest home security camera is an autonomous drone, called the Always Home Cam, that can fly around inside your home to give you a perspective of any room you want when you're not home. "Once it's done flying, the Always Home Cam returns to its dock to charge its battery," reports The Verge. "It is expected to cost $249.99 when it starts shipping next year." From the report: Jamie Siminoff, Ring's founder and "chief inventor," says the idea behind the Always Home Cam is to provide multiple viewpoints throughout the home without requiring the use of multiple cameras. In an interview ahead of the announcement, he said the company has spent the past two years on focused development of the device, and that it is an "obvious product that is very hard to build." Thanks to advancements in drone technology, the company is able to make a product like this and have it work as desired. The Always Home Cam is fully autonomous, but owners can tell it what path it can take and where it can go. When you first get the device, you build a map of your home for it to follow, which allows you to ask it for specific viewpoints such as the kitchen or bedroom. The drone can be commanded to fly on demand or programmed to fly when a disturbance is detected by a linked Ring Alarm system. The charging dock blocks the camera's view, and the camera only records when it is in flight. Ring says the drone makes an audible noise when flying so it is obvious when footage is being recorded. Ring also rolled out new hardware for the automotive market with three different devices focused on car owners: Ring Car Alarm, Car Cam, and Car Connect. The company also said they've added opt-in end-to-end video encryption, as well as the option to completely disable the "Neighbors" feed, which allows users to view local crime in real time and discuss it with people nearby.

Foreign Hackers Cripple Texas County's Email System, Raising Election Security Concerns

著者: msmash
2020年9月25日 03:48
Last week, voters and election administrators who emailed Leanne Jackson, the clerk of rural Hamilton County in central Texas, received bureaucratic-looking replies. "Re: official precinct results," one subject line read. The text supplied passwords for an attached file. But Jackson didn't send the messages. From a report: Instead, they came from Sri Lankan and Congolese email addresses, and they cleverly hid malicious software inside a Microsoft Word attachment. By the time Jackson learned about the forgery, it was too late. Hackers continued to fire off look-alike replies. Jackson's three-person office, already grappling with the coronavirus pandemic, ground to a near standstill. "I've only sent three emails today, and they were emails I absolutely had to send," Jackson said Friday. "I'm scared to" send more, she said, for fear of spreading the malware. The previously unreported attack on Hamilton illustrates an overlooked security weakness that could hamper the November election: the vulnerability of email systems in county offices that handle the voting process from registration to casting and counting ballots. Although experts have repeatedly warned state and local officials to follow best practices for computer security, numerous smaller locales like Hamilton appear to have taken few precautionary measures. U.S. Department of Homeland Security officials have helped local governments in recent years to bolster their infrastructure, following Russian hacking attempts during the last presidential election. But desktop computers used each day in small rural counties to send routine emails, compose official documents or analyze spreadsheets can be easier targets, in part because those jurisdictions may not have the resources or know-how to update systems or afford security professionals familiar with the latest practices. A ProPublica review of municipal government email systems in swing states found that dozens of them relied on homebrew setups or didn't follow industry standards. Those protocols include encryption to ensure email passwords are secure and measures that confirm that people sending emails are who they purport to be. At least a dozen counties in battleground states didn't use cloud-hosted email from firms like Google or Microsoft. While not a cure-all, such services improve protections against email hacks.

2020年9月22日 09:02
An anonymous reader quotes a report from Forbes: According to reports, more than 500,000 Activision accounts may have been hacked with login data being compromised. The eSports site Dexerto has reported that a data breach occurred on Sunday, September 20. The credentials to access these accounts are, Dexerto said, being leaked publicly, and account details changed to prevent easy recovery by the rightful owners. Activision accounts are mostly used by players of the hugely popular Call of Duty franchise. "This is a substantial breach," Martin Jartelius, CSO at Outpost24, said, "in parts, the clean-up will be a large undertaking for Activision, we can only hope backups allow restoring original contact data, resetting access and managing the users who still cannot regain access which should be a smaller group." Changing your password, if you still have access to your account, is vital, as is changing passwords at any other site or service where you use the same password. This should be to something long and strong, the use of a password manager will help you here. Developing...

Iranian Hackers Found Way Into Encrypted Apps, Researchers Say

著者: BeauHD
2020年9月19日 12:30
An anonymous reader quotes a report from The New York Times: Iranian hackers, most likely employees or affiliates of the government, have been running a vast cyberespionage operation equipped with surveillance tools that can outsmart encrypted messaging systems -- a capability Iran was not previously known to possess, according to two digital security reports released Friday. The operation not only targets domestic dissidents, religious and ethnic minorities and antigovernment activists abroad, but can also be used to spy on the general public inside Iran, said the reports byCheck Point Software Technologies, a cybersecurity technology firm, andthe Miaan Group, a human rights organization that focuses on digital security in the Middle East. The reports, which were reviewed by The New York Times in advance of their release, say that the hackers have successfully infiltrated what were thought to be secure mobile phones and computers belonging to the targets, overcoming obstacles created by encrypted applications such as Telegram and, according to Miaan, even gaining access to information on WhatsApp. Both are popular messaging tools in Iran. The hackers also have created malware disguised as Android applications, the reports said. [...] According to the report by Check Point's intelligence unit, the cyberespionage operation was set up in 2014, and its full range of capabilities went undetected for six years. Miaan traced the first the operation to February 2018 from a malicious email targeting a Sufi religious group in Iran after a violent confrontation between its members and Iranian security forces. It traced the malware used in that attack and further attacks in June 2020 to a private technology firm in Iran's northeast city of Mashhad named Andromedaa. Miaan researchers determined that Andromedaa had a pattern of attacking activists, ethnic minority groups and separatist opposition groups but also had developed phishing and malware tools that could target the general public. The hackers appeared to have a clear goal: stealing information about Iranian opposition groups in Europe and the United States and spying on Iranians who often use mobile applications to plan protests, according to the Miaan report. [...] According to Check Point, the hackers use a variety of infiltration techniques, including phishing, but the most widespread method is sending what appear to be tempting documents and applications to carefully selected targets. [...] The spyware enabled the attackers to gain access to almost any file, log clipboard data, take screenshots and steal information. According to Miaan, one application empowered hackers to download data stored on WhatsApp. In addition, the attackers discovered a weakness in the installation protocols of several encrypted applications including Telegram, which had always been deemed relatively secure, enabling them to steal the apps' installation files. These files, in turn, allow the attackers to make full use of the victims' Telegram accounts. "Although the attackers cannot decipher the encrypted communications of Telegram, their strategy makes it unnecessary," the report adds. "Rather, they use the stolen installation files to create Telegram logins to activate the app in the victims' names on another device. This enables the attackers to secretly monitor all Telegram activity of the victims."

Former Australian Prime Minister Tony Abbott had his phone number and passport details obtained by a hacker after posting a picture of his boarding pass on Instagram. From a report: Hacker Alex Hope said he uncovered Mr Abbott's details from his Qantas boarding pass in just 45 minutes. He then spent months attempting to contact Mr Abbott to alert him of the security breach. Qantas said it had now updated its cyber security protocols. Mr Abbott posted an image of a boarding pass for his flight from Sydney to Tokyo on 21 March on his Instagram account, thanking the crew. Mr Hope said he received a message from a friend daring him to hack the former prime minister as they had recently been discussing the dangers of posting your boarding pass online. The hacker explained in a blog post published on Wednesday that he was able to find Mr Abbott's information because his booking reference was printed on the boarding pass. He was then able to log in to Mr Abbott's booking and search through HTML code to find his passport number and phone number. The code also included conversations with Qantas staff about Mr Abbott. "I had Tony Abbott's passport number, phone number and weird Qantas messages about him. I was the only one who knew I had these," Mr Hope said in a blog post. "Anyone who saw that Instagram post could also have them. I felt like I had to like, tell someone about this. Someone with like, responsibilities. Someone with an email signature." Mr Hope said he contacted the Australian Signals Directorate which handles cyber security. They thanked him for bringing the issue to their attention and said they would investigate.

Billions of Devices Vulnerable To New 'BLESA' Bluetooth Spoofing Attack

著者: BeauHD
2020年9月17日 09:45
An anonymous reader writes: "Billions of smartphones, tablets, laptops, and IoT devices are using Bluetooth software stacks that are vulnerable to a new security flaw disclosed over the summer," reports ZDNet. Named BLESA (Bluetooth Low Energy Spoofing Attack), the vulnerability impacts devices running the Bluetooth Low Energy (BLE) protocol, and affects the reconnection process that occurs when a device moves back into range after losing or dropping its pairing. A successful BLESA attack allows bad actors to connect with a device (by getting around reconnection authentication requirements) and send spoofed data to it. In the case of IoT devices, those malicious packets can convince machines to carry out different or new behavior. For humans, attackers could feed a device deceptive information. BLESA impacts billions of devices that run vulnerable BLE software stacks. Vulnerable are BLE software libraries like BlueZ (Linux-based IoT devices), Fluoride (Android), and the iOS BLE stack. Windows' BLE stack is not impacted.

2020年9月16日 12:30
An anonymous reader writes: Researchers have developed and published a proof-of-concept exploit for a recently patched Windows vulnerability that can allow access to an organization's crown jewels -- the Active Directory domain controllers that act as an all-powerful gatekeeper for all machines connected to a network. CVE-2020-1472, as the vulnerability is tracked, carries a critical severity rating from Microsoft as well as a maximum of 10 under the Common Vulnerability Scoring System. Exploits require that an attacker already have a foothold inside a targeted network, either as an unprivileged insider or through the compromise of a connected device. However, when this condition is met, it's literally game over for the attacked company, as an attacker can hijack its entire network within three seconds by leveraging a bug in the Netlogon authentication protocol cryptography by adding zero characters in certain Netlogon authentication parameters, bypassing authentication procedures and then changing the password for the DC server itself. The technical report from Secura B.V., a Dutch security firm, is available here.

2020年9月16日 08:30
An anonymous reader quotes a report from CNN: The Department of Veterans Affairs said Monday that roughly 46,000 veterans had their personal information, including Social Security numbers, exposed in a data breach in which "unauthorized users" gained access to an online application used for making health care payments. A preliminary review of the incident indicated that the hackers accessed the application "to change financial information and divert payments from VA by using social engineering techniques and exploiting authentication protocols," according to the department's announcement. "The Financial Services Center (FSC) determined one of its online applications was accessed by unauthorized users to divert payments to community health care providers for the- medical treatment of Veterans. The FSC took the application offline and reported the breach to VA's Privacy Office," the statement said. "To prevent any future improper access to and modification of information, system access will not be reenabled until a comprehensive security review is completed by the VA Office of Information Technology," it added. The department is taking steps to alert veterans whose information was compromised. "To protect these Veterans, the FSC is alerting the affected individuals, including the next-of-kin of those who are deceased, of the potential risk to their personal information. The department is also offering access to credit monitoring services, at no cost, to those whose social security numbers may have been compromised," Monday's statement said. "Veterans whose information was involved are advised to follow the instructions in the letter to protect their data. There is no action needed from Veterans if they did not receive an alert by mail, as their personal information was not involved in the incident," it adds.

A Bug In Joe Biden's Campaign App Gave Anyone Access To Millions of Voter Files

著者: BeauHD
2020年9月16日 07:50
schwit1 shares a report from TechCrunch: A privacy bug in Democratic presidential candidate Joe Biden's official campaign app allowed anyone to look up sensitive voter information on millions of Americans, a security researcher has found. The campaign app, Vote Joe, allows Biden supporters to encourage friends and family members to vote in the upcoming U.S. presidential election by uploading their phone's contact lists to see if their friends and family members are registered to vote. The app uploads and matches the user's contacts with voter data supplied from TargetSmart, a political marketing firm that claims to have files on more than 191 million Americans. When a match is found, the app displays the voter's name, age and birthday, and which recent election they voted in. This, the app says, helps users find people you know and encourage them to get involved." While much of this data can already be public, the bug made it easy for anyone to access any voter's information by using the app. The App Analyst, a mobile expert who detailed his findings on his eponymous blog, found that he could trick the app into pulling in anyone's information by creating a contact on his phone with the voter's name. The Biden campaign fixed the bug and pushed out an app update on Friday. "We were made aware about how our third-party app developer was providing additional fields of information from commercially available data that was not needed," Matt Hill, a spokesperson for the Biden campaign, told TechCrunch. "We worked with our vendor quickly to fix the issue and remove the information. We are committed to protecting the privacy of our staff, volunteers and supporters will always work with our vendors to do so."

Security Researchers Detail New 'BlindSide' Speculative Execution Attack

著者: EditorDavid
2020年9月13日 03:34
"Security researchers from Amsterdam have publicly detailed 'BlindSide' as a new speculative execution attack vector for both Intel and AMD processors," reports Phoronix: BlindSide is self-described as being able to "mount BROP-style attacks in the speculative execution domain to repeatedly probe and derandomize the kernel address space, craft arbitrary memory read gadgets, and enable reliable exploitation. This works even in face of strong randomization schemes, e.g., the recent FGKASLR or fine-grained schemes based on execute-only memory, and state-of-the-art mitigations against Spectre and other transient execution attacks." From a single buffer overflow in the kernel, researchers claim three BlindSide exploits in being able to break KASLR (Kernel Address Space Layout Randomization), break arbitrary randomization schemes, and even break fine-grained randomization. There's more information on the researcher's web site, and they've also created an informational video. And here's a crucial excerpt from their paper shared by Slashdot reader Hmmmmmm: In addition to the Intel Whiskey Lake CPU in our evaluation, we confirmed similar results on Intel Xeon E3-1505M v5, XeonE3-1270 v6 and Core i9-9900K CPUs, based on the Skylake, KabyLake and Coffee Lake microarchitectures, respectively, as well as on AMD Ryzen 7 2700X and Ryzen 7 3700X CPUs, which are based on the Zen+ and Zen2 microarchitectures. Overall, our results confirm speculative probing is effective on a modern Linux system on different microarchitectures, hardened with the latest mitigations.

2020年9月11日 06:20
Joe Biden's presidential campaign was hit by an attack that was caught by Microsoft, which reportedly gathered information identifying hackers linked to the Kremlin as the most likely suspects. The Daily Beast reports: Reuters reported Thursday morning that suspected Russian state-backed hackers have attempted to breach the systems at Washington-based SKDKnickerbocker, a strategy and communications firm working hand-in-glove with Joe Biden's campaign. The attacks, which took place over the past two months, were unsuccessful. The failed hacking attempt was brought to SKDK's attention by Microsoft, which reportedly gathered information identifying hackers linked to the Kremlin as the most likely suspects. The attacks are said to have mainly focussed on phishing -- a common hacking method which lures users into disclosing sensitive passwords. That was the method used by Russian hackers to access DNC emails, which were subsequently leaked online, ahead of the 2016 presidential election. A person familiar with SKDK's repelling to the hacking attempts said the agents didn't get very far, telling Reuters: "They are well-defended, so there has been no breach." Another source said it was impossible to confirm if Biden's campaign was the target, or whether the Russians were trying to gather intel on the long list of other SKDK clients.

Ransomware incidents accounted for 41% of cyber insurance claims filed in the first half of 2020, according to a report published today by Coalition, one of the largest providers of cyber insurance services in North America. From a report: The high number of claims comes to confirm previous reports from multiple cyber-security firms that ransomware is one of today's most prevalent and destructive threats. "Ransomware doesn't discriminate by industry. We've seen an increase in ransom attacks across almost every industry we serve," Coalition added. "In the first half of 2020 alone, we observed a 260% increase in the frequency of ransomware attacks amongst our policyholders, with the average ransom demand increasing 47%," the company added. Among the most aggressive gangs, the cyber insurer listed Maze and DoppelPaymer, which have recently begun exfiltrating data from hacked networks, and threatening to release data on specialized leak sites, as part of double extortion schemes. Based on cyber insurance claims filed by customers who faced a ransomware attack in the first half of 2020, Coalition said the Maze ransomware gang was the most greedy, with the group requesting ransom demands six times larger than the overall average.

Windows 10 Themes Can Be Abused To Steal Windows Passwords

著者: msmash
2020年9月9日 09:04
AmiMoJo writes: Specially crafted Windows 10 themes and theme packs can be used in 'Pass-the-Hash' attacks to steal Windows account credentials from unsuspecting users. Windows allows users to create custom themes that contain customized colors, sounds, mouse cursors, and the wallpaper that the operating system will use. Windows users can then switch between different themes as desired to change the appearance of the operating system. A theme's settings are saved under the %AppData%\Microsoft\Windows\Themes folder as a file with a .theme extension, such as 'Custom Dark.theme.' Windows themes can then be shared with other users by right-clicking on an active theme and selecting 'Save theme for sharing,' which will package the theme into a '.deskthemepack' file. These desktop theme packs can then be shared via email or as downloads on websites, and installed by double-clicking them. This weekend security researcher Jimmy Bayne (@bohops) revealed that specially crafted Windows themes could be used to perform Pass-the-Hash attacks. Pass-the-Hash attacks are used to steal Windows login names and password hashes by tricking a user into accessing a remote SMB share that requires authentication. When trying to access the remote resource, Windows will automatically try to login to the remote system by sending the Windows user's login name and an NTLM hash of their password. In a Pass-the-Hash attack, the sent credentials are harvested by the attackers, who then attempt to dehash the password to access the visitors' login name and password.

A Single Text Is All It Took To Unleash Code-Execution Worm In Cisco Jabber

著者: BeauHD
2020年9月5日 09:45
Until Wednesday, a single text message sent through Cisco's Jabber collaboration application was all it took to touch off a self-replicating attack that would spread malware from one Windows user to another, researchers who developed the exploit said. Ars Technica reports: The wormable attack was the result of several flaws, which Cisco patched on Wednesday, in the Chromium Embedded Framework that forms the foundation of the Jabber client. A filter that's designed to block potentially malicious content in incoming messages failed to scrutinize code that invoked a programming interface known as "onanimationstart." But even then, the filter still blocked content that contained , an HTML tag that had to be included in a malicious payload. To bypass that protection, the researchers used code that was tailored to a built-in animation component called spinner-grow. With that, the researchers were able to achieve a cross-site scripting exploit that injected a malicious payload directly into the internals of the browser built into Jabber. A security sandbox built into the Chromium Embedded Framework, or CEF, would normally store the payload in a container that's isolated from sensitive parts of the app. To work around this constraint, the researchers abused the window.CallCppFunction, which is designed to open files sent by other Cisco Jabber users. By manipulating a function parameter that accepts files, the researchers were able to break out of the sandbox. "Since Cisco Jabber supports file transfers, an attacker can initiate a file transfer containing a malicious .exe file and force the victim to accept it using an XSS attack," researchers from security firm Watchcom Security wrote in a post. "The attacker can then trigger a call to window.CallCppFunction, causing the malicious file to be executed on the victim's machine." Accordingly, CVE-2020-3495, the designation assigned to the Cisco Jabber vulnerability, has a severity rating of 9.9 out of a maximum 10 based on the Common Vulnerability Scoring System. Cisco's advisory has more details here.
