Medium Threat
IP 157.20.32.163, registered to PT Intercloud Digital Inovasi in Indonesia and operating on AS152390, presents a medium-risk threat profile with a 5/10 threat level and an 87% confidence rating, driven predominantly by email spam activity. This address generated 547 total abuse reports with an activity frequency rated 8/10, indicating persistent and sustained hostile behavior across exposed services over the January 2026 reporting window.
Detection data from 20 automated honeypot sensors confirms that the dominant threat category is email spam, accounting for all recent reported incidents. The volume of reports and elevated activity frequency suggest this IP has been actively engaged in SMTP abuse, specifically mass distribution of unsolicited email, rather than isolated or opportunistic probing. The network operator, PT Intercloud Digital Inovasi, provides infrastructure within Indonesia's telecommunications ecosystem, a geographic context relevant when correlating abuse patterns with regional spam campaigns or compromised hosting environments.
Email spam at this intensity represents a concrete risk to exposed mail servers, as mass mailings consume server resources, strain bandwidth, and frequently serve as delivery mechanisms for phishing payloads or malware attachments. Attackers operating SMTP abuse from hosting providers often exploit improperly configured mail relays or use compromised servers as throwaway infrastructure to bypass basic IP reputation filters. For organizations with direct SMTP exposure to this address, the risk extends beyond nuisance to potential credential compromise or endpoint infection if recipients interact with malicious content.
Site operators should block this IP at the mail gateway firewall layer and implement strict SMTP authentication requirements, including mandatory STARTTLS and per-connection rate limiting. Deploying or subscribing to real-time IP reputation feeds will automate blocking of known spam sources. Configuring SPF, DKIM, and DMARC records on authoritative mail domains reduces the effectiveness of spoofed sender campaigns. Additionally, monitoring outbound mail queue anomalies and implementing greylisting on border mail servers can mitigate sustained abuse attempts originating from this address.
