SOLARWINDS SUPERNOVA SOFTWARE
It is unclear how long SUPERNOVA has been in the Orion software but Intezer’s malware analysis system shows a compilation timestamp of March 24, 2020. This way, the attacker can send arbitrary code to the infected device and run it in the context of the user, who most of the times has high privileges and visibility on the network.Īt the moment, the malware sample is available on VirusTotal, detected by 55 out of 69 antivirus engines. NET assembly in memory, thus leaving no artifacts on the disk of a compromised device.

The malicious code contains only one method, DynamicRun, which compiles on the fly the parameters into a. A ‘different threat actor’ may be responsible for the malware known as Supernova that has been found installed in SolarWinds Orion. The analysis shows that the threat actor added in the legitimate SolarWinds file four new parameters to receive signals from the command and control (C2) infrastructure. Microsoft: A 2nd Group May Have Also Breached SolarWinds.
SOLARWINDS SUPERNOVA MANUAL
In a technical report last week, Matt Tennis, Senior Staff Security Researcher at Palo Alto Networks, says that the malware could potentially slip even manual analysis since the code implemented in the legitimate DLL is innocuous and is of “relatively high quality.” Orion software uses the DLL to expose an HTTP API, allowing the host to respond to other subsystems when querying for a specific GIF image. NET library ( app_web_) present in the Orion software from SolarWinds, modified in a way that would allow it to evade automated defense mechanisms. The webshell is a trojanized variant of a legitimate. Named SUPERNOVA, the malware is a webshell planted in the code of the Orion network and applications monitoring platform and enabled adversaries to run arbitrary code on machines running the trojanized version of the software. While analyzing artifacts from the SolarWinds Orion supply-chain attack, security researchers discovered another backdoor that is likely from a second threat actor. An advanced persistent threat group gained long-term access to an unnamed entitys network through its Ivanti Pulse Secure VPN and SolarWinds Orion server and then installed Supernova malware.
