ClickFix finds a backup plan in PySoxy proxy chains

ClickFix, a one-shot social engineering technique that tricks victims into executing malicious workflows disguised as fixes to technical issues in their systems, has got a persistence upgrade. In a one-off instance, ReliaQuest researchers have spotted an intrusion chain using scheduled tasks, PowerShell-based command-and-control (C2), and a unique abuse of the decade-old open-source proxy tool PySoxy.…

GPUBreach exploit uses GPU memory bit-flips to achieve full system takeover

GPUBreach attack technique uses GPU memory bit-flips to escalate privileges and potentially take full control of a system. New research shows that attacks like GPUBreach exploit RowHammer bit-flips in GPU memory (GDDR6) to go beyond data corruption. Attackers can use this technique to escalate privileges and, in some cases, gain full control of the system.…

Chrome encryption bypass discovered: New malware steals passwords and cookies

A new infostealer is bypassing Chrome’s Application-Bound Encryption (ABE), using a debugger-based technique that researchers say hasn’t been observed in the wild. Called “VoidStealer,” the stealer appears to have found a way around ABE, introduced in Chrome 127 in 2024, a security control that locks sensitive browser data, such as passwords and cookies, behind stronger…

Chrome ABE bypass discovered: New VoidStealer malware steals passwords and cookies

A new infostealer is bypassing Chrome’s Application-Bound Encryption (ABE), using a debugger-based technique researchers say hasn’t been seen in the wild before. Called “VoidStealer,” the stealer seems to have found a way around ABE, introduced in Chrome 127 in 2024, a security control aimed at locking sensitive browser data like passwords and cookies behind tighter…

Researchers propose a self-distillation fix for ‘catastrophic forgetting’ in LLMs

A new fine-tuning technique aims to solve “catastrophic forgetting,” a limitation that often complicates repeated model updates in enterprise deployments. Researchers at MIT, the Improbable AI Lab, and ETH Zurich have introduced a fine-tuning method designed to let models learn new tasks while preserving previously acquired capabilities. To prevent degrading existing capabilities, many organizations isolate new tasks…

Reynolds ransomware uses BYOVD to disable security before encryption

Researchers discovered Reynolds ransomware, which uses BYOVD technique to disable security tools and evade detection before encryption. Researchers found a new ransomware, named Reynolds, that implements the Bring Your Own Vulnerable Driver (BYOVD) technique to disable security tools and evade detection before encrypting systems. Broadcom’s cybersecurity researchers initially attributed the attack to Black Basta due…
