New Mirai campaign exploits RCE flaw in EoL D-Link routers

BleepingComputer

A new campaign linked to the Mirai malware is exploiting a serious command-injection vulnerability in D-Link DIR-823X routers, identified as CVE-2025-29635. This vulnerability allows attackers to take control of the routers and integrate them into a botnet. Users of these routers are at risk as their devices can be hijacked for malicious purposes, including launching distributed denial-of-service (DDoS) attacks. This situation is particularly concerning since the affected routers are at the end of their life cycle, meaning they are unlikely to receive security updates. It’s crucial for users to be aware of this exploit and take necessary precautions to secure their networks.

Malicious KICS Docker Images and VS Code Extensions Hit Checkmarx Supply Chain

The Hacker News

Researchers have discovered that malicious Docker images were uploaded to the official 'checkmarx/kics' repository on Docker Hub. Unknown attackers managed to overwrite existing tags such as v2.1.20 and alpine, and they also created a new tag, v2.1.21, which does not match any legitimate release. This poses a significant risk to users who may unknowingly download these compromised images, potentially exposing their systems to vulnerabilities. Companies relying on these Docker images for software development or deployment should take immediate action to ensure their environments are secure. This incident highlights the ongoing challenges in securing software supply chains against malicious actors.

Mirai Botnet exploits CVE-2025-29635 to target legacy D-Link routers

Security Affairs

The Mirai botnet is exploiting a newly discovered vulnerability in older D-Link routers, identified as CVE-2025-29635. This command injection flaw allows attackers to execute arbitrary commands through specially crafted POST requests. The vulnerability is particularly concerning because it affects discontinued models that many users may still have in operation. With the public disclosure of a proof-of-concept (PoC) exploit, the risk of widespread attacks increases, putting users who have not updated their devices at significant risk. It's crucial for affected users to take immediate action to secure their routers to prevent unauthorized access.

The Supreme Court is about to decide how far geofence warrants can go

CyberScoop

The Supreme Court is set to rule on a significant legal case, Chatrie v. United States, which questions the legality of geofence warrants. Specifically, the court will address whether a single warrant can authorize a broad sweep of location data from many individuals in a given area. This case is crucial because it challenges the interpretation of 'probable cause' when law enforcement seeks to access location information from potentially everyone nearby. The outcome could have far-reaching implications for privacy rights and law enforcement practices, particularly in how they gather evidence during investigations. The decision may redefine the balance between public safety and individual privacy, impacting how similar cases are handled in the future.
