Summary

This cybersecurity brief for January 8, 2026, covers a series of critical vulnerabilities and active threats. Headlining the news are two maximum-severity (CVSS 10.0) remote code execution flaws in the n8n workflow automation platform, one unauthenticated and one authenticated, prompting urgent patching. Concurrently, a zero-day RCE is being actively exploited in end-of-life D-Link routers, with no patch forthcoming. CISA has added exploited flaws in HPE OneView and legacy PowerPoint to its KEV catalog. Major incidents include a data breach claim against broadband provider Brightspeed by the Crimson Collective, a ransomware attack on claims giant Sedgwick by TridentLocker, and a large-scale SEO poisoning campaign by the Black Cat group. Additionally, reports highlight novel phishing tactics abusing Microsoft 365 and Google Cloud services, and malicious Chrome extensions stealing AI chat data from nearly a million users.

Zero-Day in End-of-Life D-Link Routers Actively Exploited; No Patch Will Be Released

CRITICAL

Unpatched Zero-Day Vulnerability (CVE-2026-0625) in Discontinued D-Link Routers Under Active Attack

A critical zero-day command injection vulnerability, CVE-2026-0625, is being actively exploited in the wild, affecting multiple end-of-life (EOL) D-Link DSL router models. The flaw, rated 9.3 on the CVSS scale, allows unauthenticated remote attackers to execute arbitrary code by sending a malicious request to the 'dnscfg.cgi' endpoint. Exploitation has been observed since at least November 2025, with attackers using it for 'DNSChanger' style attacks. D-Link has confirmed the vulnerability but stated that since the affected products are discontinued, no security patches will be issued. Owners are strongly advised to immediately retire and replace the vulnerable devices to prevent compromise.

Black Cat Group Targets Notepad++ Users in Massive SEO Poisoning Campaign

HIGH

Black Cat Cybercrime Group Linked to SEO Poisoning Campaign Distributing Malware via Fake Notepad++ Sites

The notorious Black Cat (ALPHV) cybercrime group is behind a large-scale SEO poisoning campaign that uses malicious advertisements and manipulated search results to distribute an information-stealing backdoor. The campaign targets users searching for popular software like Notepad++. Victims are lured to convincing fake download sites, which redirect them to a GitHub clone to download a trojanized installer. The malware uses DLL side-loading to execute its payload, which is capable of stealing browser credentials, cookies, and keystrokes. A report from CNCERT/CC and ThreatBook revealed the campaign was highly effective, compromising nearly 278,000 hosts in China in just two weeks.
