CISA and the Federal Bureau of Investigation (FBI) are responding to an ongoing spearphishing campaign targeting government organizations, intergovernmental organizations, and non-governmental organizations. A sophisticated cyber threat actor leveraged a compromised end-user account from Constant Contact—a legitimate email marketing software company—to spoof a U.S. government organization and distribute links to malicious URLs.
In response, CISA and FBI have released Joint Cybersecurity Advisory AA21-148A: Sophisticated Spearphishing Campaign Targets Government Organizations, IGOs, and NGOs and Malware Analysis Report MAR-10339794-1.v1, providing tactics, techniques, and procedures (TTPs); downloadable indicators of compromise (IOCs); and recommended mitigations.
