An unprivileged Linux program can time a hardware interrupt to land in the gap between a processor sanitizing its branch predictor and the kernel using it, re-poisoning the predictor after the defense has run.

MIT CSAIL researchers Daniël Trujillo and Mengjia Yan named the technique INTERRUPT INJECTION. On an AMD Zen 2 machine running Linux 6.14 with every default Spectre v2 mitigation on,

Apparently, opening the thing is now enough. A repo can run before the first prompt, a package can hide among hundreds, and a harmless-looking PDF can finish the job.

This week runs on cheap leverage: exposed servers, recycled bugs, poisoned agent instructions, remote-access tools dressed as support software, and trusted defaults doing attackers a favor.

Nothing here is especially mystical.

Forescout found 22 internet-facing Rockwell Automation programmable logic controllers (PLCs) in cities hit by recent cyberattacks on US water utilities. Nineteen used the same mobile carrier network.

Its August 3 scan counted 4,407 exposed Rockwell controllers worldwide, including 2,844 in the United States, but Forescout could not confirm any were compromised. That figure counts exposed

Coinspect has identified CryptoJS.lib.WordArray.random() as the weak random number generator behind the Ill Bloom wallet drains.

Introduced in the JavaScript cryptography library 12 years ago, the function supplied weak entropy that affected wallet apps used to generate recovery phrases. Coinspect’s on-chain analysis puts the measured theft across two sweeps since late May at a lower bound of

Cybersecurity researchers have disclosed a security issue with Apple’s iCloud Private Relay tool that can expose a user’s real IP address.

Introduced with iOS 15, iCloud Private Relay employs a dual-hop architecture to ensure users’ privacy by routing their Safari web traffic through two relays so that no single third-party, including Apple, can determine where the request is originating from

A new class of prompt injection is spreading across commercial websites. It requires no malware, no stolen credentials, and no zero-day exploit. It abuses a standard feature built into almost every major AI assistant: pre-filled deep links.

We observed production websites embedding hidden prompt injection payloads inside “Ask AI” buttons on marketing and competitor comparison pages. When a user

Attackers broke into an organization’s Oracle database through a SQL injection flaw in a public-facing web application, then installed a post-exploitation toolkit without writing an executable to disk. They fed Java source code to the database, let Oracle compile it into stored schema objects, and ran commands from inside the database engine.

Huntress, which tracks the toolkit as khunt,

Security flaws in agent infrastructure from Amazon Web Services (AWS), Google, and Vercel let untrusted or forged instructions reach an agent’s tools with no check that a model turn had authorized them.

In several of the attack paths, the model never ran at all, so system prompts, content filters, and model-level guardrails never got a chance to intervene.

The affected products include Amazon

Cybersecurity researchers have disclosed details of a “factory-shipped backdoor” implanted in at least 20 Chinese router models from Zbtlink.

According to a new report from VulnCheck, the implant appears in all 21 firmware images currently available from Zbtlink that span more than 2 years. The backdoors are designed such that they start automatically and attempt to beacon to Chinese

A federal judge in Alexandria, Virginia, sentenced Maksim Silnikau to 16 years in prison on August 5 for creating and running Ransom Cartel, the ransomware-as-a-service operation he stood up in 2021.

Between 2021 and 2023, Ransom Cartel conspirators attacked at least 18 companies, including firms in California, New York and Nebraska, and others abroad, according to the Justice Department.
