Threat Intelligence Briefing: IP 190.89.137.220/32

Summary:

IP address 190.89.137.220/32, located in Brazil, has been associated with several observations indicative of potentially malicious activity. The intelligence gathered presents a comprehensive profile based on observed data, highlighting patterns, relationships, and neighborhood characteristics that may be relevant for SOC analysts and network defenders.

Profile and Observations:

1. Geographical Location:

- The IP address is geolocated in Brazil, with the associated ASN (Autonomous System Number) belonging to a Brazilian telecommunications provider.

2. Associated Activities:

- Historical data indicates a pattern of behavior commonly linked to command and control (C2) communications.

- The IP has been observed sending and receiving traffic at irregular intervals, characteristic of C2 traffic used by malware to communicate with its operators.

- DNS resolution activities involving the IP suggest potential domain generation algorithm (DGA) usage, often employed by malware families to dynamically generate domain names for C2 servers.

3. Traffic Patterns:

- Network traffic analysis shows bursts of data transmission interspersed with periods of inactivity, a hallmark of stealthy C2 communication.

- Encrypted traffic flows were predominantly observed, complicating further inspection but aligning with tactics used to obfuscate malicious communications.

4. Reputation and Indicators of Compromise (IoCs):

- The IP has a mixed reputation, with threat intelligence sources flagging it as part of a known malicious infrastructure.

- Previous reports have associated this IP with malware campaigns targeting specific sectors, including financial and government entities.

5. Relationships and Associated IPs:

- Analysis of network traffic and DNS logs reveals connections to a cluster of related IPs, suggesting a broader malicious infrastructure.

- Several IPs within the same ASN have shown similar traffic patterns and behaviors, indicating potential coordination or shared use.

6. Neighborhood Analysis:

- Examination of the IP’s immediate network neighborhood reveals a mix of legitimate and questionable entities.

- Some neighboring IPs have been implicated in unrelated cyber incidents, raising concerns about the security posture of the surrounding network environment.

Actionable Recommendations:

• Monitoring and Detection:

- Implement enhanced monitoring of traffic patterns associated with the IP to detect potential C2 communications.

- Use DNS filtering to block known malicious domains associated with the IP, particularly those linked to DGAs.

• Threat Hunting:

- Conduct threat hunting exercises focusing on identifying signs of compromise linked to the observed traffic patterns and behaviors.

- Investigate any internal network traffic that may correlate with the identified malicious activities.

• Incident Response:

- Prepare for potential incident response scenarios by developing playbooks that address the specific threats associated with the IP.

- Engage in information sharing with industry peers to stay updated on the latest threat intelligence related to this IP.
