Bulletproof HostingTechoff SRV Limited (AS48090)
Techoff SRV Limited is a shell-company bulletproof hosting provider exposed in Team Cymru's "Jingle Shells" investigation as using a London virtual office shared with over 1,000 co-registered companies to fabricate legitimacy. Its entire autonomous system (AS48090) is listed on Spamhaus ASN-DROP, indicating the network is leased exclusively for criminal purposes. Individual IPs accumulate thousands of independent abuse reports for webshell scans, backup file probes, SSH brute force, and bot floods.
Attack Analysis
IDS: Blocklist — Spamhaus DROP
This IP is on the Spamhaus DROP list — a dataset of netblocks hijacked or leased by professional spam and cybercrime operations with no legitimate users. Traffic from DROP-listed ranges is considered hostile by design. Blocking is unconditional.
Listed on 2 threat-intelligence blocklists
- Spamhaus DROP — Spamhaus DROP lists netblocks hijacked or leased by professional spam and cybercrime operations. Very low false-positive rate: no legitimate traffic is expected from these ranges.
- FireHOL level1 — FireHOL level1 merges DShield, Spamhaus DROP, bogon ranges and Feodo botnet servers into one curated list built for very low false positives. When DShield or Spamhaus DROP also match, this one adds no independent evidence, since it already contains them.
Port 22 Honeypot Probe
This IP connected to a fake SSH honeypot — a port 22 listener that is not a real SSH server. This is an automated scanner fingerprinting targets before launching a brute-force campaign. Legitimate systems never probe port 22 without a specific reason; this activity is virtually 100% malicious.
