GandCrab is a dangerous ransomware strain that locks users out of their files by encrypting them, demanding payment for access to be restored. Once it infects a system, it adds a distinctive eight-character extension to each file, such as ‘.xummkfvb’ or ‘.ylomkftb’, making the data unusable. Alongside this, it creates a ransom note named “recover_your_files.txt” in every directory impacted by the attack.

How GandCrab Spreads?
GandCrab primarily propagates through malicious spam email campaigns, often referred to as malspam. Cybercriminals send deceptive emails with infected attachments, typically VBScript (.vbs) files, which, when opened, trigger the download and installation of the ransomware. These emails are designed to appear trustworthy, tricking users into interacting with the attachments.
Beyond malspam, GandCrab also exploits weaknesses in outdated software, leverages malicious ads, and takes advantage of compromised websites to infect systems.

Technical Breakdown of the Attack
When the VBScript is executed, it creates a directory called “C:\WinXRAR” on the victim’s system and retrieves harmful executables, such as “Crawl.exe” and “Bootxr.exe”, from remote servers. These files are then activated using PowerShell commands. GandCrab uses advanced encryption algorithms to lock files and appends a unique four-character extension to each encrypted file.
To make recovery even more difficult, it deletes shadow copies, eliminating the possibility of restoring data through system backups unless external backups are available.
Details of the Ransom Demand
Once the encryption process is complete, GandCrab places a ransom note titled “recover_your_files.txt” in every affected folder. This note informs victims that their files have been encrypted and provides instructions for paying the ransom to obtain a decryption key. Victims are given a 72-hour deadline to contact the attackers, with warnings that failure to comply could result in permanent data loss. The contact email addresses provided are [email protected] and [email protected].
The full text of the ransom note reads as follows:
ATTENTION!
Don’t worry, your files can be recovered! All your important data, including photos, videos, and documents, has been encrypted using a robust encryption algorithm and a unique key. The only way to retrieve your files is by purchasing a decryption tool and key. Attempting to recover your files without this tool may cause irreversible damage, leaving them unrecoverable.
We strongly recommend contacting us within 72 hours to avoid losing your files permanently. Delays in communication will not be tolerated, as we may move on if you fail to respond promptly. If you don’t receive a reply within 6 hours, check your email’s “Spam” or “Junk” folder.

Identifying and Eliminating GandCrab
GandCrab is recognized by various antivirus solutions under different names. For example, Avast labels it as “Win32:MalwareX-gen [Trj]”, ESET-NOD32 identifies it as “A Variant Of Win32/Filecoder.ORR”, and Kaspersky flags it as “HEUR:Trojan-Ransom.Win32.Generic”. To eliminate the ransomware, users should rely on trusted antivirus software to scan and remove malicious files. However, removing the ransomware does not decrypt the locked files, leaving victims unable to access their data.
Strategies for Recovery and Protection
Recovering files encrypted by GandCrab without paying the ransom is extremely difficult, as no free decryption tools are currently available. Experts advise against paying the ransom, as it does not guarantee file recovery and only fuels further criminal activity. To safeguard against GandCrab and similar threats, consider the following preventive measures:
- Regular Data Backups: Store up-to-date backups of critical data on offline or external storage devices.
- Email Caution: Avoid interacting with attachments or links in unsolicited emails, particularly from unknown sources.
- Software Updates: Ensure operating systems and applications are updated to address known vulnerabilities.
- Security Tools: Install and regularly update reputable antivirus and anti-malware software.
- Network Safeguards: Deploy firewalls and intrusion detection systems to monitor and secure network traffic.
If infected, immediately disconnect the compromised device from the network to prevent further spread. Reporting the incident to law enforcement and consulting cybersecurity experts is also recommended.
