The Signal
Must Know
AI & Agents · Theregister Security
What happened
Researchers say Plugin4Shell is a zero-click remote-code-execution vulnerability affecting Claude Code, Codex, Gemini CLI, Microsoft Copilot, and GitHub Copilot; exploitation could expose assets and data reachable by the agent. [1]
The attack targets trusted plugin marketplaces rather than the underlying model or agent, and researchers say it could reach millions of users and machines. [1]
Why it matters
With automatic plugin updates enabled, swapping a pinned commit upstream can replace an installed plugin with malicious code; the researchers reported that Claude and Codex automatically update installed plugins by default. [1]
Exploitation · The Hacker News
What happened
A critical vulnerability in Check Point Security Management and Log Servers could let an unauthenticated network attacker execute code as root. [2]
Check Point released a fix through its LivePatch update channel; the supplied text truncates the statement about whether the flaw has been exploited. [2]
Why it matters
The Security Management Server controls firewall policy and administrator access, so compromise could affect those management functions. [2]

What happened
Dokploy versions 0.29.8 and 0.29.11, plus canary commit 24b02f5, are vulnerable to OS command injection during database backup creation and restoration. [4]
The vulnerable backup and restore functions incorporate user-controlled database-name or backupFile values into shell commands without shell escaping or restrictions on metacharacters. [4]
Why it matters
An authenticated user with database-backup permission can execute arbitrary commands as root on the Dokploy host because the backup operations run in the root-privileged Dokploy process. [4]
Incident · Securityaffairs
What happened
U.S. Coast Guard and FBI personnel boarded two Texas-bound energy tankers after cyberattacks struck them underway, and investigators found evidence of malicious cyber activity on at least one vessel. [5]
The VL Prosperity was a 1,093-foot Liberian-flagged crude-oil supertanker carrying about 2.3 million barrels and reportedly attacked near the Strait of Gibraltar on Aug. 7. [5]
Why it matters
Modern commercial vessels increasingly connect internet-linked systems with navigation, propulsion, steering, ballast and other critical machinery, creating potential entry points into operational technology. [5]
AI & Agents · Arstechnica Security
What happened
Anthropic disclosed that future Claude models will use SynthID-Text, Google’s open-source watermarking approach, which uses a secret key to subtly alter next-word selection so holders of the key can detect platform-generated text. [3]
Research reported in the source found that SynthID-Text can affect not only word selection but also which tools a model invokes and whether it follows or disregards trained safety guardrails. [3]
Why it matters
Under adversarial prompts intended to induce harmful actions such as revealing passwords or other sensitive information, instructions that would normally be rejected were sometimes performed after watermarking was deployed. [3]

Identity · Malwarebytes Labs
What happened
Revolut acknowledged disclosing sensitive customer records to an unauthorized party, and affected customers then reported receiving phishing texts; the source says it is not yet known whether the texts are linked to the breach. [6]
Vulnerability · Arstechnica Security
What happened
Hackers removed a Flock camera, copied most of its stored data, recovered an encryption key from the device, and used it to unlock videos containing thousands of vehicle detections. [7]
Exploitation · Theregister Security
What happened
Researchers based in China developed InjectEave, an electromagnetic side-channel technique that actively manipulates analog signals in headphones, landline handsets, and smart devices to make otherwise faint leakage detectable. [8]
