Critical Alert
IP 148.153.56.174 is a high-risk address operating from United States infrastructure (ASN AS63199, CDSC-AS1) that has generated 175 abuse reports between August 2025 and June 2026, with automated honeypot sensors flagging it primarily for hacking activity at a confidence level of 91 percent and a sustained activity frequency rated 8 out of 10.
The volume and consistency of reports spanning approximately ten months indicate persistent rather than opportunistic behavior. All 20 recent threat-category reports specifically classify the activity as hacking attempts, and the detection footprint spans 20 separate automated honeypot sensors, suggesting a methodical scanning or exploitation campaign rather than a single incident. The reported attack patterns include generic connection attempts and a Suricata intrusion detection alert referencing an invalid TLS handshake length, which points to clients attempting malformed cryptographic negotiations—often a precursor to vulnerability probing or evasion techniques designed to bypass security appliances.
The dominant hacking classification encompasses a broad spectrum of unauthorized access attempts and intrusion-related activity, from credential guessing to exploitation of vulnerable services. The TLS handshake anomaly is particularly noteworthy because attackers frequently use deliberately corrupted handshake messages to fingerprint server configurations, trigger parsing errors in misconfigured devices, or test whether security tools will process the malformed traffic without inspection. An IP with this report volume and frequency poses a concrete risk to any exposed service, especially those with TLS termination points or weak patch management.
Site operators should consider blocking or rate-limiting this address at the network edge, enforce strict TLS validation on inbound connections, and monitor logs for the specific malformed handshake pattern. Implementing defensive tools such as fail2ban or equivalent brute-force mitigation can reduce the effectiveness of continued attempts, while ensuring all exposed services are patched and follow hardening best practices will limit successful exploitation should the current activity escalate.
