Google on Monday shipped security updates to address a high-severity zero-day vulnerability in its Chrome web browser that it said is being exploited in the wild. The shortcoming, tracked as  CVE-2022-2294 , relates to a heap overflow flaw in the  WebRTC  component that provides real-time audio and video communication capabilities in browsers without the need to install plugins or download native apps. Heap buffer overflows, also referred to as heap overrun or heap smashing, occur when data is overwritten in the  heap area of the memory , leading to arbitrary code execution or a denial-of-service (DoS) condition. "Heap-based overflows can be used to overwrite function pointers that may be living in memory, pointing it to the attacker's code," MITRE  explains . "When the consequence is arbitrary code execution, this can often be used to subvert any other security service." Credited with reporting the flaw on July 1, 2022, is Jan Vojtesek from the Avast Thre...

The Cyber Police of Ukraine last week disclosed that it apprehended nine members of a criminal gang that embezzled 100 million hryvnias via hundreds of phishing sites that claimed to offer financial assistance to Ukrainian citizens as part of a campaign aimed at capitalizing on the ongoing conflict. "Criminals created more than 400 phishing links to obtain bank card data of citizens and appropriate money from their accounts," the agency  said  in a press statement last week. "The perpetrators may face up to 15 years behind bars." The law enforcement operation culminated in the seizure of computer equipment, mobile phones, bank cards as well as the criminal proceeds illicitly obtained through the scheme. Some of the rogue domains registered by the actors included ross0.yolasite[.]com, foundationua[.]com, ua-compensation[.]buzz, www.bless12[.]store, help-compensation[.]xyz, newsukraine10.yolasite[.]com, and euro24dopomoga0.yolasite[.]com, among others. The mali...

Gardeners know that worms are good. Cybersecurity professionals know that worms are  bad . Very bad. In fact, worms are literally the most devasting force for evil known to the computing world. The  MyDoom  worm holds the dubious position of most costly computer malware  ever  – responsible for some  $52 billion  in damage. In second place…  Sobig , another worm. It turns out, however, that there are exceptions to every rule. Some biological worms are actually  not welcome  in most gardens. And some cyber worms, it seems, can use their powers for good …  Meet Hopper, The Good Worm Detection tools are not good at  catching non-exploit-based propagation , which is what worms do best. Most cybersecurity solutions are less resilient to worm attack methods like token impersonation and others that take advantage of deficient internal configurations - PAM, segmentation, insecure credential storage, and more. So, what better way t...

Vulnerability coordination and bug bounty platform HackerOne on Friday disclosed that a former employee at the firm improperly accessed security reports submitted to it for personal gain. "The person anonymously disclosed this vulnerability information outside the HackerOne platform with the goal of claiming additional bounties," it  said . "In under 24 hours, we worked quickly to contain the incident by identifying the then-employee and cutting off access to data." The employee, who had access to HackerOne systems between April 4 and June 23, 2022, for triaging vulnerability disclosures associated with different customer programs, has since been terminated by the San Francisco-headquartered company as of June 30. Calling the incident as a "clear violation" of its values, culture, policies, and employment contracts, HackerOne said it was alerted to the breach on June 22 by an unnamed customer, which asked it to "investigate a suspicious vulnerabi...

Following heightened worries that U.S. users' data had been accessed by TikTok engineers in China between September 2021 and January 2022, the company sought to assuage U.S. lawmakers that it's taking steps to "strengthen data security." The admission that some China-based employees can access information from U.S. users came in a letter sent to nine senators, which further noted that the procedure requires the individuals to clear numerous internal security protocols. The contents of the letter, first  reported  by The New York Times, shares more details about TikTok's plans to address data security concerns through a multi-pronged initiative codenamed "Project Texas." "Employees outside the U.S., including China-based employees, can have access to TikTok U.S. user data subject to a series of robust cybersecurity controls and authorization approval protocols overseen by our U.S.-based security team," TikTok CEO Shou Zi Chew wrote in the m...

Microsoft has detailed the evolving capabilities of toll fraud malware apps on Android, pointing out its "complex multi-step attack flow" and an improved mechanism to evade security analysis. Toll fraud belongs to a category of billing fraud wherein malicious mobile applications come with hidden subscription fees, roping in unsuspecting users to premium content without their knowledge or consent. It's also different from other  fleeceware threats  in that the malicious functions are only carried out when a compromised device is connected to one of its target network operators. "It also, by default, uses cellular connection for its activities and forces devices to connect to the mobile network even if a Wi-Fi connection is available," Dimitrios Valsamaras and Sang Shin Jung of the Microsoft 365 Defender Research Team  said  in an exhaustive analysis. "Once the connection to a target network is confirmed, it stealthily initiates a fraudulent subscription...

Google on Thursday announced a slew of improvements to its  password manager  service aimed at creating a more consistent look and feel across different platforms. Central to the changes is a "simplified and unified management experience that's the same in Chrome and Android settings," Ali Sarraf, Google Chrome product manager,  said  in a blog post. The updates are also expected to automatically group multiple passwords for the same sites as well as introduce an option to manually add passwords. Although Google appears to be not ready yet to make Password Manager as a standalone app, users on Android can now add a shortcut to it on the homescreen. In a related change on iOS, should users opt for Chrome as the  default autofill provider , Password Manager now comes with the ability to generate unique, strong passwords. The built-in Password Checkup feature on Android is receiving an upgrade of its own too. Beyond checking for hacked credentials, it can f...

A newly discovered malware has been put to use in the wild at least since March 2021 to backdoor Microsoft Exchange servers belonging to a wide range of entities worldwide, with infections lingering in 20 organizations as of June 2022. Dubbed  SessionManager , the malicious tool masquerades as a module for Internet Information Services ( IIS ), a web server software for Windows systems, after exploiting one of the ProxyLogon flaws within Exchange servers.  Targets included 24 distinct NGOs, government, military, and industrial organizations spanning Africa, South America, Asia, Europe, Russia and the Middle East. A total of 34 servers have been compromised by a SessionManager variant to date. This is far from the first time the technique has been  observed in real-world attacks . The use of a rogue IIS module as a means to distribute stealthy implants has its echoes in an Outlook credential stealer called  Owowa  that came to light in December 2021. "Dropp...

Fixing indirect vulnerabilities is one of those complex, tedious and, quite frankly, boring tasks that no one really wants to touch. No one except for  Debricked , it seems. Sure, there are lots of ways to do it manually, but can it be done automatically with minimal risk of breaking changes? The Debricked team decided to find out.  A forest full of fragile trees So, where do you even start? Firstly, there needs to be a way to fix the vulnerability, which, for indirect dependencies, is no walk in the park. Secondly, it needs to be done in a safe way, or, without anything breaking.  You see, indirect dependencies are introduced deep down the dependency tree and it's very tricky to get to the exact version you want. As Debricked's Head of R&D once put it, " You are turning the knobs by playing around with your direct dependencies and praying to Torvalds that the correct indirect packages are resolved. When Torvalds is in your favour, you have to sacrifice some clou...

Amazon, in December 2021, patched a high severity vulnerability affecting its  Photos app  for Android that could have been exploited to steal a user's access tokens. "The Amazon access token is used to authenticate the user across multiple Amazon APIs, some of which contain personal data such as full name, email, and address," Checkmarx researchers João Morais and Pedro Umbelino  said . "Others, like the Amazon Drive API, allow an attacker full access to the user's files." The Israeli application security testing company reported the issue to Amazon on November 7, 2021, following which the tech giant rolled out a fix on December 18, 2021. The leak is the result of a misconfiguration in one of the app's components named "com.amazon.gallery.thor.app.activity.ThorViewActivity" that's defined in the  AndroidManifest.xml file  and which, when launched, initiates an HTTP request with a header containing the access token. In a nutshell, it...

A cloud threat actor group tracked as 8220 has updated its malware toolset to breach Linux servers with the goal of installing crypto miners as part of a long-running campaign. "The updates include the deployment of new versions of a crypto miner and an IRC bot," Microsoft Security Intelligence said in a series of tweets on Thursday. "The group has actively updated its techniques and payloads over the last year." 8220, active since early 2017 , is a Chinese-speaking, Monero-mining threat actor so named for its preference to communicate with command-and-control (C2) servers over port 8220. It's also the developer of a tool called whatMiner, which has been co-opted by the Rocke cybercrime group in their attacks. In July 2019, the Alibaba Cloud Security Team uncovered an extra shift in the adversary's tactics, noting its use of rootkits to hide the mining program. Two years later, the gang resurfaced with Tsunami IRC botnet variants and a custom ...

Google's Threat Analysis Group (TAG) on Thursday disclosed it had acted to block as many as 36 malicious domains operated by hack-for-hire groups from India, Russia, and the U.A.E. In a manner analogous to the  surveillanceware ecosystem , hack-for-hire firms equip their clients with capabilities to enable targeted attacks aimed at corporates as well as activists, journalists, politicians, and other high-risk users. Where the two stand apart is that while customers purchase the spyware from commercial vendors and then deploy it themselves, the operators behind hack-for-hire attacks are known to conduct the intrusions on their clients' behalf in order to obscure their role. "The hack-for-hire landscape is fluid, both in how the attackers organize themselves and in the wide range of targets they pursue in a single campaign at the behest of disparate clients," Shane Huntley, director of Google TAG,  said  in a report. "Some hack-for-hire attackers openly adver...

One of the commissioners of the U.S. Federal Communications Commission (FCC) has renewed calls asking for Apple and Google to boot the popular video-sharing platform TikTok from their app stores citing "its pattern of surreptitious data practices." "It is clear that TikTok poses an unacceptable national security risk due to its extensive data harvesting being combined with Beijing's apparently unchecked access to that sensitive data," Brendan Carr, a Republican member of the FCC,  wrote  in a letter to Apple and Google's chief executives. TikTok, in September 2021,  disclosed  that there are one billion people who use its app every month, making it one of the largest social media platforms after Facebook, YouTube, WhatsApp, Instagram, and WeChat. Carr further emphasized that the short-form video service is far from just an app for sharing funny videos or memes, calling out its features as "sheep's clothing" intended to mask its core funct...

Shadow IT refers to the practice of users deploying unauthorized technology resources in order to circumvent their IT department. Users may resort to using shadow IT practices when they feel that existing IT policies are too restrictive or get in the way of them being able to do their jobs effectively. An old school phenomenon  Shadow IT is not new. There have been countless examples of widespread shadow IT use over the years. In the early 2000s, for example, many organizations were reluctant to adopt Wi-Fi for fear that it could undermine their security efforts. However, users wanted the convenience of wireless device usage and often deployed wireless access points without the IT department's knowledge or consent. The same thing happened when the iPad first became popular. IT departments largely prohibited iPads from being used with business data because of the inability to apply group policy settings and other security controls to the devices. Even so, users often ignored IT ...

A former Canadian government employee this week agreed to plead guilty in the U.S. to charges related to his involvement with the NetWalker ransomware syndicate. Sebastien Vachon-Desjardins , who was  extradited to the U.S.  on March 10, 2022, is accused of conspiracy to commit computer fraud and wire fraud, intentional damage to a protected computer, and transmitting a demand in relation to damaging a protected computer. The 34-year-old IT consultant from Gatineau, Quebec, was initially apprehended in January 2021 following a coordinated  law enforcement operation  to dismantle the dark web infrastructure used by the NetWalker ransomware cybercrime group to publish data siphoned from its victims. The takedown also brought its activities to a standstill. A search warrant executed at Vachon-Desjardins's home in Canada resulted in the seizure of 719 bitcoin, valued at approximately $28.1 million at the time, and $790,000 in Canadian currency. In February 2022, the ...

The notorious North Korea-backed hacking collective Lazarus Group is suspected to be behind the recent $100 million altcoin theft from Harmony Horizon Bridge, citing similarities to the  Ronin bridge attack  in March 2022. The finding comes as Harmony  confirmed  that its Horizon Bridge, a  platform  that allows users to move cryptocurrency across different blockchains, had been breached last week. The incident involved the exploiter carrying out multiple transactions on June 23 that extracted tokens stored in the bridge and subsequently making away with about $100 million in cryptocurrency. "The stolen crypto assets included Ether (ETH), Tether (USDT), Wrapped Bitcoin (WBTC) and BNB," blockchain analytics company Elliptic  said  in a new report. "The thief immediately used Uniswap – a decentralized exchange (DEX) – to convert much of these assets into a total of 85,837 ETH." Days later, on June 27, the culprit is said to have begun moving f...

Cybersecurity researchers have documented a new information-stealing malware that targets YouTube content creators by plundering their authentication cookies. Dubbed "YTStealer" by Intezer, the malicious tool is likely believed to be sold as a service on the dark web, with it distributed using fake installers that also drop RedLine Stealer and Vidar. "What sets YTStealer aside from other stealers sold on the dark web market is that it is solely focused on harvesting credentials for one single service instead of grabbing everything it can get ahold of," security researcher Joakim Kennedy said in a report shared with The Hacker News. The malware's modus operandi, however, mirrors its counterparts in that it extracts the cookie information from the web browser's database files in the user's profile folder. The reasoning given behind targeting content creators is that it uses one of the installed browsers on the infected machine to gather YouTube channe...

A new security vulnerability has been disclosed in RARlab's UnRAR utility that, if successfully exploited, could permit a remote attacker to execute arbitrary code on a system that relies on the binary. The flaw, assigned the identifier CVE-2022-30333, relates to a path traversal vulnerability in the Unix versions of UnRAR that can be triggered upon extracting a maliciously crafted RAR archive. Following responsible disclosure on May 4, 2022, the shortcoming was addressed by RarLab as part of  version 6.12  released on May 6. Other versions of the software, including those for Windows and Android operating systems, are not impacted. "An attacker is able to create files outside of the target extraction directory when an application or victim user extracts an untrusted archive," SonarSource researcher Simon Scannell  said  in a Tuesday report. "If they can write to a known location, they are likely to be able to leverage it in a way leading to the execution of arb...
