Threat hunters are calling attention to a new variant of a remote access trojan (RAT) called Chaos RAT that has been used in recent attacks targeting Windows and Linux systems. According to findings from Acronis, the malware artifact may have been distributed by tricking victims into downloading a network troubleshooting utility for Linux environments. "Chaos RAT is an open-source RAT written in Golang, offering cross-platform support for both Windows and Linux systems," security researchers Santiago Pontiroli, Gabor Molnar, and Kirill Antonenko said in a report shared with The Hacker News. "Inspired by popular frameworks such as Cobalt Strike and Sliver, Chaos RAT provides an administrative panel where users can build payloads, establish sessions, and control compromised machines." While work on the "remote administration tool" started way back in 2017, it did not attract attention until December 2022 , when it was put to use in a malicious campaig...

Traditional data leakage prevention (DLP) tools aren't keeping pace with the realities of how modern businesses use SaaS applications. Companies today rely heavily on SaaS platforms like Google Workspace, Salesforce, Slack, and generative AI tools, significantly altering the way sensitive information is handled. In these environments, data rarely appears as traditional files or crosses networks in ways endpoint or network-based DLP tools can monitor. Yet, most companies continue using legacy DLP systems, leaving critical security gaps. A new white paper, Rethinking DLP For The SaaS Era: Why Browser-Centric DLP is the New Mandate , identifies precisely why current DLP methods struggle to secure modern SaaS-driven workflows. It also explores how browser-native security addresses these gaps by focusing security efforts exactly where user interactions occur, in the browser. Why Traditional DLP Tools Fall Short Traditional DLP solutions were built for a simpler time when sensitive...

Several malicious packages have been uncovered across the npm, Python, and Ruby package repositories that drain funds from cryptocurrency wallets, erase entire codebases after installation, and exfiltrate Telegram API tokens, once again demonstrating the variety of supply chain threats lurking in open-source ecosystems. The findings come from multiple reports published by Checkmarx, ReversingLabs, Safety, and Socket in recent weeks. The list of identified packages across these platforms are listed below - Socket noted that the two malicious gems were published by a threat actor under the aliases Bùi nam, buidanhnam, and si_mobile merely days after Vietnam ordered a nationwide ban on the Telegram messaging app late last month for allegedly not cooperating with the government to tackle illicit activities related to fraud, drug trafficking, and terrorism. "These gems silently exfiltrate all data sent to the Telegram API by redirecting traffic through a command-and-control (C2...

Hewlett Packard Enterprise (HPE) has released security updates to address as many as eight vulnerabilities in its StoreOnce data backup and deduplication solution that could result in an authentication bypass and remote code execution. "These vulnerabilities could be remotely exploited to allow remote code execution, disclosure of information, server-side request forgery, authentication bypass, arbitrary file deletion, and directory traversal information disclosure vulnerabilities," HPE said in an advisory. This includes a fix for a critical security flaw tracked as CVE-2025-37093, which is rated 9.8 on the CVSS scoring system. It has been described as an authentication bypass bug affecting all versions of the software prior to 4.3.11. The vulnerability, along with the rest, was reported to the vendor on October 31, 2024. According to the Zero Day Initiative (ZDI), which credited an anonymous researcher for discovering and reporting the shortcoming, said the problem is...

Threat hunters are alerting to a new campaign that employs deceptive websites to trick unsuspecting users into executing malicious PowerShell scripts on their machines and infect them with the NetSupport RAT malware. The DomainTools Investigations (DTI) team said it identified "malicious multi-stage downloader Powershell scripts" hosted on lure websites that masquerade as Gitcode and Docusign. "These sites attempt to deceive users into copying and running an initial PowerShell script on their Windows Run command," the company said in a technical report shared with The Hacker News. "Upon doing so, the powershell script downloads another downloader script and executes on the system, which in turn retrieves additional payloads and executes them eventually installing NetSupport RAT on the infected machines." It's believed that these counterfeit sites may be propagated via social engineering attempts over email and/or social media platforms. The Po...
