New Malware Discovered in SolarWinds Attack that Used 7-Zip Code to Hide

Sunburst was installed through the SolarWinds Orion update in early July 2020, and 2 computers were jeopardized. Subsequently Teardrop was set up the next day.

Raindrop Model

Raindrop is quite comparable to Teardrop where they act as a loader for Cobalt Strike Beacon. Raindrop is compiled as a DLL, which is constructed from a modified version of 7-Zip source code.

No proof has actually been uncovered of Raindrop being straight included with Sunburst. However, it appears in other places on networks where at least one computer has actually been affected and jeopardized by Sunburst.

Raindrop, though similar to Teardrop has some extremely significant distinctions. Teardrop was provided by the Sunburst backdoor, whereas Raindrop is used for spreading out throughout the victims network.

The Raindrop malware installed an extra file called “7z. Within hours a legitimate variation of 7zip was utilized to extract a copy of what appeared to be Directory Services Internals (DSInternals) onto the computer.

An extra piece of malware used in the SolarWinds attacks has actually been revealed by scientists at Symantec, a department of Broadcom. Raindrop (Backdoor.Raindrop) is a loader that delivers a payload of Cobalt Strike.

An active directory site inquiry tool, in addition to a credential dumper developed particularly for SolarWinds Orion databases was found on that computer system. On another previously uninfected computer system, Raindrop was set up under the name bproxy.dll, eleven hours later.

An additional tool called mc_store. exe was later installed by the aggressors on this computer. The tool is an unidentified PyInstaller packaged application. No additional activity was observed on this computer.

Call file of the Export Directory Table is “” 7-zip. dll” and the Export Names are:


And among the following is picked at random:
