On 23 July 2020, the FBI disseminated the FLASH message “Chinese Government-Mandated Tax Software Contains Malware, Enabling Backdoor Access” (AC-000129-TT) after the FBI observed reporting of malware distributed through Chinese Government-mandated tax software. FLASH message AC-000129-TT provided several indicators of compromise (IOCs) and a summary of security risks associated with the “Golden Tax System” tax software.
The FBI is disseminating this FLASH message based on the identification of additional IOCs and tactics, techniques, and procedures (TTPs) associated with the malware. The FBI advises all organizations conducting business in China to review FLASH message AC-000129-TT. Observed TTPs associated with the malware can be mapped to the MITRE1 Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK2) for Enterprise framework, Version 7.0.
