Researchers at Cisco’s Talos Security Team have highlighted a malware-A-Service operator who used public github accounts as a channel to distribute the classification of malicious software to the goals.

The use of Github gave Malware-e-Saravis (MAAS) a reliable and easy-to-use platform, which is a greenlight in many enterprise networks that rely on code repository for software developed by them. Github removed three accounts that hosted malicious payloads soon after being notified by Talos.

“In addition to being an easy means of hosting files, downloading files from a github repository can bypass web filtering that has not been configured to block Github domain,” Talos researcher Chris Neel and Craig Jackson Written on Thursday“While some organizations can block Github in their environment to curb the use of open-sources aggressive tooling and other malware, many organizations with software development teams require some capacity github access in some capacity. In these environment, it may be difficult to differentiate from a malicious GITHUB download regular web traffic.

Emmenhtal, meet amadey

The campaign, which had said Tellos, that had been running since February, used the already known malware loader, which was tracked under names including Imnehatal and Pikalaite. Safety firm researcher Palo Alto Network And Ukraine’s major state cyber agency SSSCIP Already in a separate campaign, the use of Emmenhtal was documented that embedded the loader in a malicious email to distribute malware to Ukrainian institutions. Talos found the same emmenhtal version in the MAAS operation, only this time the loader was distributed through Github.

The campaign using Github was different from targeting Ukrainian institutions in another major way. While the last payload in one that targets Ukrainian institutions was a malicious backdoor, known as Smochelder, Githib One Install Amaede, a separate malware platform. Amadey was first seen in 2018 and was initially used to assemble boatnets. Tellos stated that the primary function of Amadey is to collect system information from infected equipment and download a set of secondary payloads adapted to their personal characteristics, depending on specific objectives in various campaigns.
