Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) are warning enterprises of cyberattacks launched from the Tor network. Threat actors use Tor to carry out malicious activities including system compromise, data exfiltration, denial of service (DoS) attacks, and also reconnaissance. CISA recommends organizations to adopt necessary measures to block and monitor Tor network traffic, to identify attacks in an early stage. The risk of being the target of malicious activity routed through Tor is unique to each organization.”]
