Security researchers have uncovered a widespread phishing operation that leverages adversary‑in‑the‑middle techniques to compromise Microsoft 365 accounts. By routing malicious sign‑ins through residential proxies, attackers masquerade as legitimate user traffic, then sift through compromised inboxes to locate employees handling payroll and financial processes. The campaign highlights how attackers are increasingly focusing on high‑value email communications within organizations.

PortSwigger has uncovered a significant development in web security research. An AI-assisted hacking tool, known as HTTP Terminator, built by James Kettle, has identified novel HTTP desynchronization techniques after examining 30,000 candidate attack vectors. This breakthrough comes alongside a separate human-guided discovery cascade that exposed a zero-day vulnerability in Apache Traffic Server.

A recent disclosure by Malcolm Stagg highlights a dangerous combination of techniques: leveraging Windows Hello for Business keys to keep footholds in Entra ID environments, and exploiting NAT connection states to hijack active sessions and spoof DNS responses. The research, presented at Black Hat USA 2026, introduces the NatJack attack class, showing how network infrastructure can be manipulated to expose victim IPs, map ports, and exhaust NAT tables, all while maintaining persistent access through compromised identity keys.

A recent security study uncovered a startling vulnerability: a lone GitHub issue opened by an unauthorised account could trigger code execution on CI runners in Anthropic’s and Google’s agent repositories, and even hijack the next OpenAI agent run. The researchers demonstrated the attack in a controlled environment and presented their findings at Black Hat USA. This article explains how the flaw works, why it matters for AI developers, and what steps can be taken to harden CI pipelines against similar threats.

A detailed forensic investigation has connected the threat actor known as TeamPCP to a series of Redis server compromises dating back to 2020, years before the group shifted focus to software supply chain infiltration. Researchers identified overlapping command-and-control domains, shared malware staging methods, and consistent backend infrastructure patterns that link early opportunistic attacks to recent high-profile campaigns. This discovery reshapes the timeline of TeamPCP's operations, suggesting a deliberate progression from scanning misconfigured databases to executing sophisticated supply chain compromises. The findings underscore how threat actors often refine their tradecraft through lower-stakes intrusions before pursuing higher-value targets.

Researchers have uncovered a fresh side‑channel technique that leverages hardware interrupt timing to slip past existing Spectre v2 defenses on both Intel and AMD processors. The method, dubbed INTERRUPT INJECTION, allows an unprivileged Linux program to re‑poison a CPU’s branch predictor after mitigation routines have supposedly secured it, potentially leaking sensitive data. This discovery highlights a subtle timing window that current software patches may not fully close, prompting a reevaluation of how branch‑prediction mitigations are applied in modern kernels.

A recent investigation uncovered a critical flaw in the JavaScript cryptography library CryptoJS that has led to millions of dollars in losses. The issue stems from a poorly designed random number generator used to create wallet recovery phrases, affecting five popular wallet applications. On‑chain analysis reveals at least two theft events since late May, with a lower‑bound loss of $5.7 million.

Apple բազմաթիվ iCloud Private Relay, launched with iOS 15, was designed to protect user privacy WITHOUT Apple or any third‑party seeing the originating IP. However, a newly discovered flaw in the WebKit proxy layer can reveal the real IP address behind the double‑hop architecture. This article explains the mechanics of the flaw, its consequences, and how users and security teams can respond. The vulnerability stems from a bypass that enables malicious websites to force Safari to use the first relay directly, thereby exposing the user’s diplomacy to the attacker. Understanding how this works is essential for IT professionals and power users who rely on Apple’s privacy ecosystem.

Artificial intelligence assistants have become a staple on modern websites, offering instant answers through convenient Ask AI widgets. While these features boost engagement, they also open a covert attack vector that requires no malware, stolen credentials, or exotic exploits. By embedding malicious prompts inside the very links that launch the assistant, threat actors can subtly reshape the model’s internal context and steer its recommendations without the user’s knowledge.

Recent research uncovered critical vulnerabilities in the agent infrastructure of major cloud providers, allowing attackers to send forged instructions directly to underlying tools without model approval. Because the model is never invoked in these paths, traditional safeguards such as system prompts and content filters are bypassed, exposing systems to unauthorized actions.
