New Evooo1Bot Linux Botnet Turns Routers into Traffic Relays
Evooo1Bot is a new Mirai-based Linux botnet targeting internet-facing routers to convert them into SOCKS5 traffic relay nodes, expanding attack surfaces.
Why it matters
This botnet leverages gateway devices to anonymize traffic, increasing risks of abuse and network reconnaissance that SOC teams must detect and address.
SOC impact
Monitor for indicators of compromise associated with Evooo1Bot infections, especially unusual SOCKS5 proxy activity on routers. Validate the presence of affected internet-facing devices and investigate any anomalous network relay behavior to contain potential misuse.
Recommended actions
- Identify internet-facing routers in the network environment
- Review network traffic for suspicious SOCKS5 relay activity
- Monitor router logs for unauthorized connections or configurations
- Investigate anomalies in outbound network traffic paths
- Correlate threat intelligence related to Evooo1Bot activity
Executive Summary
Evooo1Bot is a newly identified Linux malware strain based on the Mirai botnet lineage, specifically targeting routers exposed to the internet. It converts compromised routers into SOCKS5 proxy nodes, enabling anonymized traffic relaying. This modular approach broadens the attack surface by abusing gateway devices for indirect network access. For security operations, this development emphasizes the importance of scrutinizing internet-facing routers for signs of compromise and monitoring for unusual proxy activity that could indicate abuse or reconnaissance efforts.
