Microsoft develops a new scanner to detect hidden backdoors in LLMs
Effectiveness of the scanner: Microsoft said the scanner does not require retraining models or prior knowledge of backdoor behavior and operates using forward passes only, avoiding gradient calculations or backpropagation to keep computing costs low.The company also said it works with most causal, GPT-style language models and can be used across a wide range of…

Swarmer Tool Abuses Windows Registry to Evade Detection and Persist on Systems
Swarmer, a sophisticated tool designed to manipulate Windows registry hives while bypassing endpoint detection systems. The tool exploits legacy Windows infrastructure to achieve persistent access without triggering traditional EDR monitoring systems that typically flag direct registry modifications. Endpoint Detection and Response (EDR) solutions have significantly hardened defenses against conventional registry persistence techniques. Classic methods using…

PDFSIDER Malware Actively Exploited to Evade Antivirus and EDR Defenses
Security researchers have identified a sophisticated backdoor malware variant, PDFSIDER, that leverages DLL side-loading to evade endpoint detection and response (EDR) systems. The threat demonstrates advanced persistent threat (APT) tradecraft, combining evasion mechanisms with encrypted command-and-control capabilities to maintain covert access on compromised systems. PDFSIDER’s infection chain originates through spear-phishing campaigns delivering ZIP archives containing…

EDRStartupHinder: Blocks Antivirus EDR at Windows 11 25H2 Startup (Defender Included)
A cybersecurity researcher has unveiled EDRStartupHinder, a proof-of-concept tool that prevents antivirus and endpoint detection and response (EDR) solutions from launching during Windows startup, including Microsoft Defender on Windows 11 25H2. The technique exploits Windows Bindlink API functionality through the bindflt.sys driver to interfere with security software initialization. The tool builds on previous research into Bindlink…

Why FIM Add-Ons Aren’t Integrity Monitoring ( Why EDR Still Isn’t Enough)
<div cla If you are running a strong EDR platform, you’re doing something right. EDR is essential. It’s great at detecting and responding to malicious activity: suspicious processes, behaviors, lateral movement, and indicators of compromise. But here’s the uncomfortable truth: EDR does not tell you, with certainty, whether your systems are still in a known and…

Cybersecurity Awareness: Why Centralized Monitoring Is No Longer Optional
In today’s digital world, cybersecurity is no longer just an IT problem, it is a business survival requirement. Organizations are deploying multiple tools such as firewalls, EDR, databases, operating systems, cloud platforms, WAFs, proxies, and more. However, simply deploying tools does not guarantee security. What truly matters is how effectively you monitor, correlate, and respond…

Moonwalk++ Bypasses EDR by Spoofing Windows Call Stacks
A new Moonwalk++ proof-of-concept (PoC) shows how malware can spoof Windows call stacks while staying encrypted in memory, bypassing modern EDR detection. The research highlights blind spots in stack-based telemetry increasingly relied on by enterprise defenders. “Public detection tools fail entirely to recognize the call stack tampering,” said the researcher. Moonwalk++ Shows the Limits of…
