Threat actors are exploiting tax season with numerous campaigns leveraging tax themes to deliver malware, remote monitoring tools, fraud attempts, and credential phishing. Over a hundred campaigns have been observed in 2026, with a notable increase in remote monitoring and management (RMM) payloads. Tactics include impersonating tax agencies, claiming expired documents, and requesting tax filing support. While primarily targeting the United States, campaigns have also been observed in Canada, Australia, Switzerland, and Japan. Notable actors include TA4922, a newly designated threat group delivering malware from the Winos4.0 ecosystem, and TA2730, focusing on credential phishing for financial institutions. Business email compromise actors are also using tax form lures to steal financial and personal data. These campaigns demonstrate the ongoing exploitation of timely and topical themes by cybercriminals to deceive users.

A large-scale attack infrastructure dubbed TruffleNet has been identified, built around the open-source tool TruffleHog. This infrastructure is used to systematically test compromised credentials and perform reconnaissance across AWS environments. The campaign involves over 800 unique hosts across 57 distinct Class C networks, characterized by consistent configurations and the use of Portainer. Alongside TruffleNet, adversaries are exploiting Amazon Simple Email Service (SES) to facilitate Business Email Compromise (BEC) campaigns. The attackers create email identities using compromised WordPress sites and conduct aggressive cloud reconnaissance. This activity highlights the evolving tactics of threat actors in exploiting cloud infrastructure at scale, combining credential theft, reconnaissance automation, and SES abuse to conduct high-volume fraud with minimal detection.
