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.
Bad Bot Flood
This IP generated over 20 HTTP 4xx errors in 60 seconds using a User-Agent identified as a bad bot (scraper, headless browser, or attack proxy). The high error rate indicates automated probing for vulnerabilities while trying to appear as generic traffic. Legitimate services respect robots.txt and do not flood servers with errors.
