Description of Campaign
Threat actors targeted the Olympic Games in China and tried to infect systems with malware. The unidentified threat actors tried to reconfigure webservers by uploading scripts as well as deploy web shells to allow access to the systems. Many of the utilities that were used are available through code sharing sites, such as GitHub, and might be used by security practitioners to test security posture and identify vulnerabilities.
Our ATR Team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports. This campaign was researched by Avast and posted publically.
