Bazar - S0534 (99fdf3b4-96ef-4ab9-b191-fc683441cad0)

Bazar is a downloader and backdoor that has been used since at least April 2020, with infections primarily against professional services, healthcare, manufacturing, IT, logistics and travel companies across the US and Europe. Bazar reportedly has ties to TrickBot campaigns and can be used to deploy additional malware, including ransomware, and to steal sensitive data.(Citation: Cybereason Bazar July 2020)
