Hackers Exploit c-ares DLL Side-Loading to Bypass Security and Deploy Malware
Security experts have disclosed details of an active malware campaign that’s exploiting a DLL side-loading vulnerability in a legitimate binary associated with the open-source c-ares library to bypass security controls and deliver a wide range of commodity trojans and stealers.
“Attackers achieve evasion by pairing a malicious libcares-2.dll with any signed version of the legitimate ahost.exe (which they often rename) to execute their code,” Trellix said in a report shared with The Hacker News. “This DLL side-loading technique allows the malware to bypass traditional signature-based security defenses.”
The campaign has been observed distributing a wide assortment of malware, such as Agent Tesla, CryptBot, Formbook, Lumma Stealer, Vidar Stealer, Remcos RAT, Quasar RAT, DCRat, and XWorm.
New Malware Campaign Delivers Remcos RAT Through Multi-Stage Windows Attack
Cybersecurity researchers have disclosed details of a new campaign dubbed SHADOW#REACTOR that employs an evasive multi-stage attack chain to deliver a commercially available remote administration tool called Remcos RAT and establish persistent, covert remote access.
“The infection chain follows a tightly orchestrated execution path: an obfuscated VBS launcher executed via wscript.exe invokes a PowerShell downloader, which retrieves fragmented, text-based payloads from a remote host,” Securonix researchers Akshay Gaikwad, Shikha Sangwan, and Aaron Beardslee said in a technical report shared with The Hacker News.
“These fragments are reconstructed into encoded loaders, decoded in memory by a. NET Reactor–protected assembly, and used to fetch and apply a remote Remcos configuration. The final stage leverages MSBuild.exe as a living-off-the-land binary (LOLBin) to complete execution, after which the Remcos RAT backdoor is fully deployed and takes control of the compromised system.”
Malicious Chrome Extension Steals MEXC API Keys by Masquerading as Trading Tool
Cybersecurity researchers have disclosed details of a malicious Google Chrome extension that’s capable of stealing API keys associated with MEXC, a centralized cryptocurrency exchange (CEX) available in over 170 countries, while masquerading as a tool to automate trading on the platform.
The extension, named MEXC API Automator (ID: pppdfgkfdemgfknfnhpkibbkabhghhfh), has 29 downloads and is still available on the Chrome Web Store as of writing. It was first published on September 1, 2025, by a developer named “jorjortan142.”
“The extension programmatically creates new MEXC API keys, enables withdrawal permissions, hides that permission in the user interface (UI), and exfiltrates the resulting API key and secret to a hardcoded Telegram bot controlled by the threat actor,” Socket security researcher Kirill Boychenko said in an analysis.
New VoidLink malware framework targets Linux cloud servers
A newly discovered advanced cloud-native Linux malware framework named VoidLink focuses on cloud environments, providing attackers with custom loaders, implants, rootkits, and plugins designed for modern infrastructures.
VoidLink is written in Zig, Go, and C, and its code shows signs of a project under active development, with extensive documentation, and likely intended for commercial purposes.
Malware analysts at cybersecurity company Check Point say that VoidLink can determine if it runs inside Kubernetes or Docker environments and adjust its behavior accordingly.

Questions to inspire discussion.
🤖 Q: How will the US military become an AI-first warfighting force?
A: The Department of War will implement continuous experimentation, conduct quarterly force-on-force combat labs, and deploy AI coordinated swarms across all domains from Pentagon back offices to tactical front lines, building on the military AI lead established during President Trump’s first term.
🎯 Q: What defines responsible AI for military applications?
A: The Department of War defines responsible AI as objectively truthful and mission-relevant capabilities employed securely within laws governing military activities, focusing on factually accurate models without ideological constraints limiting lawful military applications.

Facebook login thieves now using browser-in-browser trick
Hackers over the past six months have relied increasingly more on the browser-in-the-browser (BitB) method to trick users into providing Facebook account credentials.
The BitB phishing technique was developed by security researcher mr.d0x in 2022. Cybercriminals later adopted it in attacks targeting various online services, including Facebook and Steam.
Trellix researchers monitoring malicious activity say that threat actors steal Facebook accounts to spread scams, harvest personal data, or commit identity fraud. With more than three billion active users, the social network is still a prime target for fraudsters.
