A recent wave of cyber attacks targeting financial services, private equity, and professional services is attributed to a data extortion group known as UNC6671. "UNC6671 continues to rely on voice phishing (vishing) to target enterprise employees, posing as IT help desk staff facilitating mandatory, urgent security migrations. Significantly, the threat actor often contacts employees via their

WordPress has fixed a pre-authentication reflected cross-site scripting (XSS) flaw in its login screen that affects every version of the content management system. Under additional conditions, the bug can be chained into PHP code execution on the server. Tracked as CVE-2026-64638 (CVSS score: 8.9), the High-severity vulnerability requires no attacker privileges. According to pwn.ai,

Open Source had a great childhood. For two decades it got to be a kid. It ran around barefoot, gave everything away, trusted strangers, and never once thought about who was watching. It ran the kind of lemonade stand that took IOUs from anyone who wandered up — take what you need, pay me back whenever, no need to leave a name. It was idyllic. It was also, in retrospect, a little feral. Then,

A use-after-free bug in Linux's SCTP networking code can be turned into full root on a host, and Tencent researchers say they used it to escape a container and reach the machine underneath. The flaw has existed since 2008. The fix already shipped: stable kernels 7.1.6, 6.18.42, 6.12.101 and 6.6.148, released August 3, close it. Anyone running an older kernel with SCTP reachable should update.

Cybersecurity researchers have called attention to an active "widespread email-driven phishing campaign" that employs adversary-in-the-middle (AitM) techniques to take control of Microsoft 365 accounts with an aim to identify key personnel involved in financial workflows and gather related email. "The campaign uses residential proxies to disguise malicious sign-ins as ordinary consumer traffic,

PortSwigger says HTTP Terminator, an artificial intelligence (AI)-assisted research system built by James Kettle, generated and proved new HTTP desynchronization techniques after exploring 30,000 candidate attack vectors. PortSwigger said a separate human-guided discovery cascade also exposed a zero-day in Apache Traffic Server. Kettle said HTTP Terminator tested 30,000 websites where scanning

Security researcher Malcolm Stagg has disclosed a new attack class called NatJack that manipulates network address translation (NAT) connection state to hijack active TCP sessions, spoof DNS responses, expose mapped ports, and exhaust NAT tables. Presented at Black Hat USA 2026, the research found affected behavior across independently developed implementations, including Windows and

Security researcher Malcolm Stagg has disclosed a new attack class called NatJack that manipulates network address translation (NAT) connection state to hijack active TCP sessions, spoof DNS responses, disclose victim IP addresses and mapped ports, and exhaust NAT tables. Presented at Black Hat USA 2026, Stagg said the techniques were demonstrated across network infrastructure devices

A GitHub issue opened by an account with no repository privileges was enough to execute code on the CI runners behind Anthropic's and Google's own coding-agent repositories. On OpenAI's, it was enough to hijack the next agent run. Novee Security ran the attack against each vendor's agent in the configuration that the vendor ships by default, and presented the work at Black Hat USA on August 5.

UNIX systems (including Linux) are well-known to record a lot of activities in many different locations. But there is one domain where they definitely lack of "modern" logging: shells. Most shells provide an historization of the typed commands through a flat file in the $HOME directory (ex: $HOME/.bash_history). They suffer of multiple problems:

A new analysis has uncovered that the threat actor tracked as TeamPCP has been active on the cybercrime scene as far back as 2020, indicating the group has been compromising internet-facing infrastructure for years before training their sights on the software supply chain. "The connection is supported by overlapping domains, malware deployment paths, staging techniques, backend infrastructure,
