Block access from NMS to the Internet and if it is explicitly needed, limit destinations (think Zero-Trust networking). If you have an NMS other than SolarWinds Orion, don’t rest (yet). You can follow us on Linkedin, Twitter, Facebook for daily Cybersecurity, and hacking news updates. If you have SolarWinds but not Orion, consider mapping your attack surface in case those were also compromised in the supply chain attack. Raindrop is used to move laterally and deploy payloads on other computers. It provides insights into the intentions of the attackers. The discovery of Raindrop is a very significant step in the investigation of the SolarWinds hack attacks.

Execute the decrypted payload as shellcode.

This is simple XOR with byte key and as such does not impact compression ratio. The malware will then perform the following actions:

Locates start of the encoded payload which is embedded within legitimate 7-Zip machine code.

We've summarized key threat actors that are evidenced to be part of the Russian cyber attack landscape.

Executes some computation to delay execution. Cold war tactics are alive and well in cyberspace.

party software vendor known as SolarWinds. This malicious thread performs the following actions: But what little we know has cybersecurity experts extremely worried with some describing the attack as a literal wakeup call. Whenever the DLL is loaded, it starts a new thread from the DllMain subroutine that executes the malicious code. Name file of the Export Directory Table is “”7-zip.dll” and the Export Names are:Īnd one of the following is selected at random:

Raindrop is compiled as a DLL, which is built from a modified version of 7-Zip source code. Raindrop is very much similar to Teardrop where they act as a loader for Cobalt Strike Beacon. No further activity was observed on this computer. The tool is an unknown PyInstaller packaged application.

DSInternals is a legitimate tool that can be used for querying Active Directory servers and retrieving data, typically passwords, keys, or password hashes.Īn additional tool called mc_store.exe was later installed by the attackers on this computer. Within hours a legitimate version of 7zip was used to extract a copy of what appeared to be Directory Services Internals (DSInternals) onto the computer. (Reuters) - The group behind the SolarWinds cyber attack identified late last year is now targeting government agencies, think tanks, consultants, and non-governmental organizations, Microsoft Corp. The Raindrop malware installed an additional file called “7z.dll” an hour later. On another previously uninfected computer, Raindrop was installed under the name bproxy.dll, eleven hours later. Subsequently Teardrop was installed the next day.Īn active directory query tool, as well as a credential dumper designed specifically for SolarWinds Orion databases was found on that computer.

Sunburst was installed through the SolarWinds Orion update in early July 2020, and two computers were compromised. However, it appears elsewhere on networks where at least one computer has been affected and compromised by Sunburst. No evidence has been uncovered of Raindrop being directly involved with Sunburst.
