How to remove Raspberry Robin malware from your computer

What kind of malware is Raspberry Robin?

Raspberry Robin is a highly sophisticated malware (worm) known for evading detection and employing unique tactics. In the past year, it has become one of the most widely distributed malware in use by various threat actors to distribute other malicious software, including Clop ransomware and IcedID.

More about Raspberry Robin

Raspberry Robin is a member of the group of malware that actively avoids running on virtual machines. The malware incorporates numerous evasion techniques, making it a challenging task to debug it. The malware's main component can be downloaded through several entry vectors, the most common being an LNK disguised as a thumb drive or a network share.

The main Raspberry Robin routine incorporates both authentic and counterfeit payloads. Once sandboxing tools are detected, the fake payload is loaded in order to avoid detection and analysis of the genuine malware routine by security and analytics tools.

At the same time, the actual payload of the malware stays hidden behind layers of obfuscation and eventually establishes a connection to the Tor network.

Payloads

As mentioned in the introduction, cybercriminals have been observed using Raspberry Robin to deliver payloads such as Clop and IcedID. Clop is ransomware that encrypts files, modifies filenames, and drops a ransom note. Cybercriminals use this malware to extort money from victims.

IceID is a Trojan capable of executing various commands on infected devices, injecting additional malware, and more. Cybercriminals can also use Raspberry Robin to inject other pieces of malware such as cryptocurrency miners, remote administration Trojans, clippers, and other malicious software.

Conclusion

Raspberry Robin is a dangerous malware that can cause significant damage to computer systems. Its sophisticated evasion techniques make it challenging to debug and analyze, allowing the malware to remain undetected by security and analytics tools. The malware can download various payloads, including ransomware like Clop and Trojans like IcedID.

How did Raspberry Robin infiltrate my computer?

Raspberry Robin's distribution method involves infecting USB drives, which can result in infection when connected to a system. When an infected USB is inserted, the malware initially presents itself as a shortcut or LNK file.

The LNK file contains a command line that runs a genuine executable to download a Windows Installer (MSI) package, triggering the infection chain upon double-clicking the LNK file.

Other malware distribution channels include email attachments, infected websites or downloads, social engineering tactics, and exploit kits that target vulnerabilities in software. Malicious actors can also use social media platforms, messaging apps, and Peer-to-Peer networks to spread malware.

How to avoid installation of malware?

Practice secure browsing routines and exercise caution when downloading or clicking on links. This includes avoiding suspicious websites, email attachments, and pop-ups and using a reputable antivirus program to detect and remove malware. Keeping programs and operating systems up to date with the latest security patches can also help prevent malware attacks.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Update 8 February 2024: Upon its initial execution on a computer, Raspberry Robin will automatically try to increase its control over the device by exploiting various vulnerabilities known as 1-day exploits. Also, the latest Raspberry Robin version introduces new features to evade detection and enhance its functionality.

It checks for hooked APIs and terminates legitimate system processes like RunLegacyCPLElevated.exe and runonce.exe. Also, the malware implements evasion tactics to prevent shutdowns and evade Unified Write Filter (UWF) drivers.

It also uses PAExec.exe for remote process execution instead of PsExec.exe. Communication methods are adjusted, with the malware attempting to contact legitimate Tor domains before randomly selecting from a list of hardcoded V3 onion addresses. Despite these changes, the encryption and communication mechanisms between Raspberry Robin and its command-and-control (C2) servers remain consistent.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.

If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:

Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

Restart your computer into Safe Mode:

Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.

In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
