CoTDeceptor:Adversarial Code Obfuscation against CoT-Enhanced LLM Code Agents

LLM-based code agentse.g., ChatGPT Codex are increasingly deployed as detector for code review and security auditing tasks. Although CoT-enhanced LLM vulnerability detectors are believed to provide improved robustness against obfuscated malicious code, we find that their reasoning chains and...

Strengthening supply chain security: Preparing for the next malware campaign

The open source ecosystem continues to face organized, adaptive supply chain threats that spread through compromised credentials and malicious package lifecycle scripts. The most recent example is the multi-wave Shai-Hulud campaign. While individual incidents differ in their mechanics and speed,...

DREAM: Dynamic Red-Teaming across Environments for AI Models

Large Language Models LLMs are increasingly used in agentic systems, where their interactions with diverse tools and environments create complex, multi-stage safety challenges. However, existing benchmarks mostly rely on static, single-turn assessments that miss vulnerabilities from adaptive,...

Efficient Jailbreak Mitigation Using Semantic Linear Classification in a Multi-Staged Pipeline

Prompt injection and jailbreaking attacks pose persistent security challenges to large language model LLM-based systems. We present an efficient and systematically evaluated defense architecture that mitigates these threats through a lightweight, multi-stage pipeline. Its core component is a...

GhostPoster Malware Found in 17 Firefox Add-ons with 50,000+ Downloads

A new campaign named GhostPoster has leveraged logo files associated with 17 Mozilla Firefox browser add-ons to embed malicious JavaScript code designed to hijack affiliate links, inject tracking code, and commit click and ad fraud. The extensions have been collectively downloaded over 50,000...

Phantom Stealer Spread by ISO Phishing Emails Hitting Russian Finance Sector

Cybersecurity researchers have disclosed details of an active phishing campaign that's targeting a wide range of sectors in Russia with phishing emails that deliver Phantom Stealer via malicious ISO optical disc images. The activity, codenamed Operation MoneyMount-ISO by Seqrite Labs, has primari...

From Obfuscated to Obvious: A Comprehensive JavaScript Deobfuscation Tool for Security Analysis

JavaScript's widespread adoption has made it an attractive target for malicious attackers who employ sophisticated obfuscation techniques to conceal harmful code. Current deobfuscation tools suffer from critical limitations that severely restrict their practical effectiveness. Existing tools...

Fake OSINT and GPT Utility GitHub Repos Spread PyStoreRAT Malware Payloads

Cybersecurity researchers are calling attention to a new campaign that's leveraging GitHub-hosted Python repositories to distribute a previously undocumented JavaScript-based Remote Access Trojan RAT dubbed PyStoreRAT. "These repositories, often themed as development utilities or OSINT tools,...

Persistent Backdoor Attacks under Continual Fine-Tuning of LLMs

Backdoor attacks embed malicious behaviors into Large Language Models LLMs, enabling adversaries to trigger harmful outputs or bypass safety controls. However, the persistence of the implanted backdoors under user-driven post-deployment continual fine-tuning has been rarely examined. Most prior...
