CISA Gave Three Linux Kernel Bugs a Three-Day Deadline

The catalogue entries share a deadline, not necessarily an attacker or exploit chain. Each Linux kernel flaw needs its own exposure check.
Current analysis, technical guidance and reporting across security, infrastructure, automation and artificial intelligence.

The catalogue entries share a deadline, not necessarily an attacker or exploit chain. Each Linux kernel flaw needs its own exposure check.

An attacker using valid credentials may blend into ordinary traffic. A carefully placed account, token or file that nobody should touch can create a different kind of warning.

A legitimate login did not mean legitimate intent. Spain's data-protection authority describes an alleged AI-agent attack, while warning that the organisation's report still needs analysis.

A successful MFA login is one security decision. The token used afterwards is another. NIST's final guidance gives cloud buyers better questions to ask about that second boundary.

US authorities have seized domains used by NightmareStresser. The service allegedly enabled hundreds of thousands of DDoS attacks or attempts since 2022, illustrating how cheaply disruption can be purchased.

ESET's new SparroWocky analysis shows an espionage backdoor manipulating Windows internals and borrowing open-source components. The important clue is what a trusted-looking process is doing, not just its name.

An AI agent successfully repaired a failing application by changing the shared model behind it. The repair worked, but other behaviour changed too. Who approved the new model?

Cisco's review found missing authentication, injection and other weaknesses in Nexus Dashboard. The important patch question is which control-plane build is actually running.

Holding comments for approval sounds like a sensible defence. These Events Calendar takeover chains can reach the vulnerable code while the comment is still pending.

A forged token hit the wrong product in a honeypot. Replayed against vulnerable WSO2 software, it worked. An old patch now deserves a fresh look at the gateway protecting your APIs.

A corporate security block did not always end the conversation. A joint advisory describes attackers asking targets to open disguised malware on personal devices instead, where the exposure can extend beyond work data.

The upload handler checked a permitted-file list supplied by the person uploading the file. Wordfence says attackers have been exploiting that mistake for months, despite a fix being available.
