Attack Analysis

WordPress: Brute Force Attack
This IP was blocked attempting to log into a WordPress site's wp-login.php — either from a disallowed country or after exceeding the allowed number of failed login attempts. Automated credential-stuffing and brute-force tools account for the overwhelming majority of this traffic; legitimate users rarely trigger a hard IP block on login alone.
IDS: Threat Intel — CINS Active Threat
This IP appears in the CINS (Collective Intelligence Network Security) Active Threat Intelligence feed — a real-time blocklist of IPs with poor reputation scores derived from observed malicious activity. CINS-listed IPs are actively engaged in attacks at the time of detection.
IDS: Blocklist — Dshield
This IP was reported to the DShield community blocklist by multiple independent security sensors worldwide. DShield aggregates firewall logs from thousands of contributors; IPs on this list are confirmed active attackers observed across many networks.
