📊 Threat Analysis

Threat intelligence analysis has linked 157.0.147.155 to malicious activity originating from Suzhou, China, operating on the network of China Unicom Jiangsu Province Network. The address has been under observation since its initial detection. Over a period of 35 days, this IP generated 793 malicious requests, averaging approximately 22.7 requests per day.

Security Intelligence

💡 Server-Side Request Forgery (SSRF)

SSRF attacks trick servers into making requests to internal resources that should not be publicly accessible. This can expose cloud metadata endpoints, internal APIs, and private network services, potentially leading to full infrastructure compromise.

💡 State-Sponsored Cyber Operations

Nation-state actors conduct sophisticated campaigns for espionage, sabotage, and influence operations. Their resources exceed typical criminal organizations, enabling zero-day exploitation, long-term persistent access, and attacks on critical infrastructure.
