Google on Thursday released software updates to address yet another zero-day flaw in its Chrome web browser. Tracked as  CVE-2022-4135 , the high-severity vulnerability has been described as a heap buffer overflow in the GPU component. Clement Lecigne of Google's Threat Analysis Group (TAG) has been credited with reporting the flaw on November 22, 2022. Heap-based buffer overflow bugs can be  weaponized  by threat actors to crash a program or execute arbitrary code, leading to unintended behavior. According to the NIST's National Vulnerability Database, the flaw could permit a "remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page." "Google is aware that an exploit for CVE-2022-4135 exists in the wild," the tech giant  acknowledged  in an advisory. But like other actively exploited issues, technical specifics have been withheld until a majority of the users are updated with a fix and t...

An analysis of firmware images across devices from Dell, HP, and Lenovo has revealed the presence of outdated versions of the  OpenSSL  cryptographic library, underscoring a supply chain risk. EFI Development Kit, aka  EDK , is an open source implementation of the Unified Extensible Firmware Interface ( UEFI ), which functions as an interface between the operating system and the firmware embedded in the device's hardware. The firmware development environment, which is in its second iteration (EDK II), comes with its own cryptographic package called  CryptoPkg  that, in turn, makes use of services from the OpenSSL project. Per firmware security company Binarly, the firmware image associated with Lenovo Thinkpad enterprise devices was found to use three different versions of OpenSSL: 0.9.8zb, 1.0.0a, and 1.0.2j, the last of which was released in 2018. What's more, one of the firmware modules named InfineonTpmUpdateDxe relied on OpenSSL version 0.9.8zb that w...

A coordinated law enforcement effort has dismantled an online phone number spoofing service called  iSpoof  and arrested 142 individuals linked to the operation. The websites, ispoof[.]me and ispoof[.]cc, allowed the crooks to "impersonate trusted corporations or contacts to access sensitive information from victims," Europol  said  in a press statement. Worldwide losses exceeded €115 million ($ 119.8 million), with over 200,000 potential victims believed to have been directly targeted through iSpoof in the U.K. alone, the Metropolitan Police  noted .  Among the 142 people arrested is the administrator of the website, who was apprehended in the U.K. on November 6, 2022. The website and its server were subsequently seized and taken offline two days later by Ukrainian and U.S. agencies. Per the National Police Corps, the helpdesk fraud  allowed  registered subscribers on the online portal to mask their phone numbers and make calls impersonatin...

Interpol on Thursday  announced  the seizure of $130 million worth of virtual assets in connection with a global crackdown on cyber-enabled financial crimes and money laundering. The international police operation, dubbed  HAECHI-III , transpired between June 28 and November 23, 2022, resulting in the arrests of 975 individuals and the closure of more than 1,600 cases. This comprised two fugitives wanted by South Korea for their supposed involvement in a Ponzi scheme to embezzle €28 million from 2,000 victims. Another instance pertained to a call center scam based out of India, wherein a group of criminals impersonated Interpol and Europol officers to trick victims in Austria into transferring funds. The call centers operated from New Delhi and Noida. The illegal activity informed the victims that their "identities were stolen and crime pertaining to narcotics drugs were committed in their names," forcing them to make a money transfer. "In order to clear themselve...

The operators of the RansomExx ransomware have become the latest to develop a new variant fully rewritten in the Rust programming language, following other strains like  BlackCat ,  Hive , and  Luna . The latest version, dubbed RansomExx2 by the threat actor known as Hive0091 (aka DefrayX), is primarily designed to run on the Linux operating system, although it's expected that a Windows version will be released in the future. RansomExx, also known as Defray777 and Ransom X, is a  ransomware   family  that's known to be active since 2018. It has since been linked to a number of attacks on government agencies, manufacturers, and other high-profile entities like Embraer and GIGABYTE. "Malware written in Rust often benefits from lower [antivirus] detection rates (compared to those written in more common languages) and this may have been the primary reason to use the language," IBM Security X-Force researcher Charlotte Hammond  said  in a report p...

A set of five medium-severity security flaws in Arm's Mali GPU driver has continued to remain unpatched on Android devices for months, despite fixes released by the chipmaker. Google Project Zero, which discovered and reported the bugs, said Arm addressed the shortcomings in July and August 2022. "These fixes have not yet made it downstream to affected Android devices (including Pixel, Samsung, Xiaomi, Oppo, and others)," Project Zero researcher Ian Beer  said  in a report. "Devices with a Mali GPU are currently vulnerable." The vulnerabilities, collectively tracked under the identifiers  CVE-2022-33917  (CVSS score: 5.5) and  CVE-2022-36449  (CVSS score: 6.5), concern a case of improper memory processing, thereby allowing a non-privileged user to gain access to freed memory. The second flaw, CVE-2022-36449, can be further weaponized to write outside of buffer bounds and disclose details of memory mappings, according to an  advisory  issued ...

The cyber espionage group known as Bahamut has been attributed as behind a highly targeted campaign that infects users of Android devices with malicious apps designed to extract sensitive information. The activity, which has been active since January 2022, entails distributing rogue VPN apps through a fake SecureVPN website set up for this purpose, Slovak cybersecurity firm ESET  said  in a new report shared with The Hacker News. At least eight different variants of the spyware apps have been discovered to date, with them being trojanized versions of legitimate VPN apps like SoftVPN and OpenVPN . None of these apps are available on Google Play Store. The tampered apps and their updates are pushed to users through the fraudulent website. It's also suspected that the targets are carefully selected, since launching the app requires the victim to enter an activation key to enable the features. This implies the use of an undetermined distribution vector, although past evide...

The Android banking fraud malware known as SharkBot has reared its head once again on the official Google Play Store, posing as file managers to bypass the app marketplace's restrictions. A majority of the users who downloaded the rogue apps are located in the U.K. and Italy, Romanian cybersecurity company Bitdefender  said  in an analysis published this week. SharkBot, first  discovered  towards the end of 2021 by Cleafy, is a  recurring   mobile   threat  distributed both on the Google Play Store and other third-party app stores. One of the trojan's primary goals is to initiate money transfers from compromised devices via a technique called "Automatic Transfer System" ( ATS ), in which a transaction triggered via a banking app is intercepted to swap the payee account with an actor-controlled account in the background. It's also capable of serving a fake login overlay when users attempt to open legitimate banking apps, stealing the credent...
