Our monitoring infrastructure has identified 188.212.135.72, geolocated to Warsaw, Poland, operating on the network of F.N.S. HOLDINGS LIMITED, as a source of suspicious network activity. During its 27-day observation window, we recorded 1,639 hostile requests from this IP — roughly 60.7 per day on average. This address belongs to a datacenter or cloud hosting provider. Hosting IPs are frequently leveraged by threat actors who rent cheap VPS instances specifically for conducting attacks. With 3 different attack patterns detected, this IP exhibits behavior characteristic of advanced automated scanning frameworks. Poland currently accounts for 588 blocked IPs in our database, making it a major source of malicious traffic. A score of 305/100 places this address in the top tier of severity.

This IP belongs to a hosting or data center provider. Malicious traffic from hosting infrastructure often originates from compromised VPS instances, rented servers used for scanning campaigns, or abused free-tier cloud accounts. Hosting providers typically respond to abuse reports within 24-72 hours.
Distributed denial of service attacks overwhelm infrastructure with traffic volume. Effective mitigation combines always-on traffic scrubbing, anycast network distribution, rate limiting, and the ability to quickly scale absorption capacity during attacks.
Immutable, offline backups remain the most effective defense against ransomware. The 3-2-1 rule — three copies on two media types with one offsite — combined with regular recovery testing ensures business continuity after encryption attacks.
