Minerva Labs has announced that the company conducted a thorough review of the cybersecurity threat exposed by the SolarWinds breach. Minerva Labs reports a dramatic increase in the number of prevented events coming from the “SolarWinds.BusinessLayerHost.exe” process in the past few months.

Researchers suspect that this activity is related to the current event and advise other security vendors to monitor for such behavior. While security vendors published their mitigation recommendations in the past few days, Minerva reports that the company successfully prevented related attempts since August 2020.

Here’s an example of a prevented memory injection attack in Minerva’s interface:

Example #1:

Example #2:

As detailed by FireEye’s report (which can be found here), the malicious backdoor refuses to work when certain blacklisted processes are present in the operating system, proving once again the effectiveness of the Minerva approach and the Hostile Environment Simulation module which is one of the main parts of Minerva’s pre-execution threat prevention platform. Thousands of such artifacts simulate the presence of security and forensics tools that creates an environment in which malware refrains from executing.
