Patchwork is an Indian threat actor that has been active since December 2015 and usually targets Pakistan via spear phishing attacks. Patchwork has used malicious RTF files to drop a variant of the BADNEWS (Ragnatela) RAT in recent campaign targeting medical researchers
A new variant of the BADNEWS RAT called Ragnatela being distributed via spear phishing emails to targets of interest in Pakistan. Ragnatela, which means spider web in Italian, is also the project name and panel used by Patchwork APT.
Ragnatela RAT features with the following capabilities:
- Executing commands via cmd
- Capturing screenshots
- Logging Keystrokes
- Collecting list of all the files in victim’s machine
- Collecting list of the running applications in the victim’s machine at a specific time periods
- Downing addition payloads
- Uploading files
Patchwork lures them with documents impersonating Pakistani authorities for distribution. For example, a document called EOIForm.rtf was uploaded by the threat actor onto their own server at karachidha[.]org/docs/. The file contains an exploit which is meant to compromise the victim’s computer and execute the final payload (RAT).That payload is stored within the RTF document as an OLE object.
Ragnatela RAT communicates with the attacker’s infrastructure via a server located at bgre.kozow[.]com. Prior to launching this campaign, the threat actor tested that their server was up and running properly.
