Three campaigns. One has Cobalt Strike ready. RDP nearly quadrupled. A botnet picked up a new CVE. And someone built a Kubernetes cluster just to exploit n8n. A preview of what GreyNoise customers get every week. Full brief has the IOCs, attribution, and analysis.

A dark-themed “Weekly Intelligence Brief” report from GreyNoise covering February 2–9, 2026, summarizing global malicious scanning activity. Large headline text highlights a 113% week‑over‑week surge in Remote Desktop Protocol (RDP) attacks, with 29.9 million RDP attempts, 83,000 N8N exploits, and 352 callback domains associated with OAST. Below, the layout is divided into four sections: one explaining that RDP attacks more than doubled in a week driven by a single noisy IP; one titled “Ivanti ‘Three‑Headed Hydra’” describing three independent campaigns abusing CVE‑2022‑1281 with Cobalt Strike; one on N8N exploitation describing 83,334 attempts against CVE‑2022‑21858 from a specific IP range and warning about exposed API keys; and one on the Rondodx botnet summarizing high session counts and links to previous activity. A footer invites readers to contact GreyNoise for the full brief and includes a link to the company website.

Three campaigns. One fingerprint. React RCE, VPN brute forcing, and router scanning—all linked to the same infrastructure.→ 1.7M React attacks → 506K VPN targets → 3 IPs behind 1.8M router attempts This week's At The Edge preview: greynoise.io/contact

A digital intelligence brief from GreyNoise titled “AT THE EDGE,” dated January 19–23, 2026, summarizing three coordinated cyber campaigns under the headline “Three Campaigns. One Fingerprint.” The top of the graphic highlights key statistics in large text: 1.7M React attacks, 506K VPN targets, 1.8M router attempts, and a note that 3 IPs are responsible for 99% of observed activity. Below, four text blocks describe: (1) React exploitation attempts related to CVE-2025-55182, including real command injection, a Metasploit module, and one hosting provider generating 57% of traffic; (2) sustained attacks on enterprise VPNs (Fortinet SSL VPN and Palo Alto GlobalProtect) with 506K sessions, a 25% increase over baseline for Fortinet, and emphasis that VPN credentials are valuable for ransomware; (3) router attacks where three IPs drive 1.8M attempts, focusing on a MikroTik RouterOS brute-force campaign with a 64,000:1 session-to-IP ratio and noting compromised routers as pivot points and botnet nodes; and (4) an explanation that a shared JA1T network fingerprint links the React RCE, VPN brute force, and environment crawling to common infrastructure, suggesting organized operations rather than random scanning. The bottom banner invites GreyNoise customers to access the full brief, mentioning complete IOCs, attribution, detection guidance, and weekly role-based recommendations, with a contact URL “greynoise.io/contact” and a small 2026 GreyNoise, Inc. copyright notice.
