Critical Threat
IP 124.198.131.162 is a high-risk address with a maximum threat score of 10/10, linked to confirmed hacking activity including TCP stream anomalies detected by automated honeypot sensors. The IP has accumulated 233 abuse reports over approximately two months, with a detection confidence of 94 percent, indicating that security monitoring systems have consistently identified this address as a source of malicious traffic rather than misattributed noise.
The activity window spans from March 2026 through April 2026, with reports sourced exclusively from automated honeypot sensors. All 233 reports categorise the observed activity under hacking, and the network is associated with ASN AS210558 operated by 1337 Services GmbH. A specific Suricata alert pattern has been documented: the signature "SURICATA STREAM Packet with broken ack" indicates that this host has been sending malformed TCP acknowledgment packets toward honeypot endpoints, a technique commonly employed during port scanning, service fingerprinting, or attempts to evade detection by disrupting stateful inspection. While the activity frequency score of 3/10 suggests the attacks are not occurring at maximum intensity, the sustained volume of reports over a two-month period demonstrates persistent, deliberate targeting of exposed network sensors rather than incidental scanning traffic.
TCP stream manipulation and broken acknowledgment attacks represent a reconnaissance and evasion technique that can precede more targeted exploitation. Broken ACK packets may be used to test firewall and intrusion-prevention system responses, map network topology, or establish footholds for subsequent intrusion attempts. The consistent generation of these anomalies across multiple honeypot sensors indicates that the operator of 124.198.131.162 is systematically probing internet-facing services and deliberately fragmenting or corrupting TCP state to bypass security appliances that rely on stateful packet inspection. For any organisation with exposed SSH, RDP, HTTP or other services, this activity signals an active threat actor performing pre-exploitation reconnaissance.
Site operators should treat this IP address as hostile and block it at the network perimeter using firewall rules or existing blocklists, ideally synchronising with community-driven abuse feeds for automated updates. Rate-limiting incoming connections to exposed services reduces the effectiveness of scanning patterns. Implementing fail2ban or equivalent authentication-hardening tools on SSH and administrative interfaces helps mitigate credential-guessing attempts that often follow reconnaissance. Enabling Suricata or Snort rules to alert and drop packets matching broken-ack signatures adds an additional defensive layer. Continuous monitoring of honeypot telemetry and logging will support early detection if this actor shifts tactics or targets new infrastructure.
