Mallox ransomware activities in 2023 have witnessed a 174% increase when compared to the previous year, new findings from Palo Alto Networks Unit 42 reveal. "Mallox ransomware, like many other ransomware threat actors, follows the double extortion trend: stealing data before encrypting an organization's files, and then threatening to publish the stolen data on a leak site as leverage to convince victims to pay the ransom fee," security researchers Lior Rochberger and Shimi Cohen said in a new report shared with The Hacker News.
Threat actors are taking advantage of Android's WebAPK technology to trick unsuspecting users into installing malicious web apps on Android phones that are designed to capture sensitive personal information. "The link contained in the message led to a site that used WebAPK technology to install a malicious application on the victim's device."
Microsoft Word documents exploiting known remote code execution flaws are being used as phishing lures to drop malware called LokiBot on compromised systems. The Word file that weaponizes CVE-2021-40444 contains an external GoFile link embedded within an XML file that leads to the download of an HTML file, which exploits Follina to download a next-stage payload, an injector module written in Visual Basic that decrypts and launches LokiBot.
Rockwell Automation says a new remote code execution exploit linked to an unnamed Advanced Persistent Threat group could be used to target unpatched ControlLogix communications modules commonly used in manufacturing, electric, oil and gas, and liquified natural gas industries.The company teamed up with the U.S. Cybersecurity and Infrastructure Security Agency to analyze the exploit linked to APT threat actors, but they have yet to share how they obtained it.
Cybersecurity researchers and threat actors are targeted by a fake proof of concept CVE-2023-35829 exploit that installs a Linux password-stealing malware. The fake PoC claims to be an exploit for CVE-2023-35829, a high-severity use-after-free flaw impacting the Linux kernel before 6.3.2.

Microsoft blocked code signing certificates predominantly used by Chinese hackers and developers to sign and load malicious kernel mode drivers on breached systems by exploiting a Windows policy loophole. With Windows Vista, Microsoft introduced policy changes restricting how Windows kernel-mode drivers could be loaded into the operating system, requiring developers to submit their drivers for review and sign them through Microsoft's developer portal.
A Microsoft Windows policy loophole has been observed being exploited primarily by native Chinese-speaking threat actors to forge signatures on kernel-mode drivers. "Actors are leveraging multiple open-source tools that alter the signing date of kernel mode drivers to load malicious and unverified drivers signed with expired certificates," Cisco Talos said in an exhaustive two-part report shared with The Hacker News.
VMware warned customers today that exploit code is now available for a critical vulnerability in the VMware Aria Operations for Logs analysis tool, which helps admins manage terabytes worth of app and infrastructure logs in large-scale environments. Recently, VMware issued another alert about a now-patched critical bug in VMware Aria Operations for Networks, allowing remote command execution as the root user and being actively exploited in attacks.
Malicious actors exploited an unknown flaw in Revolut's payment systems to steal more than $20 million of the company's funds in early 2022. The development was reported by the Financial Times, citing multiple unnamed sources with knowledge of the incident.
