Edfr789 is a malicious ransomware variant that encrypts a victim’s files, rendering them inaccessible until a ransom is paid. Upon infection, it appends a unique four-character extension to each file, such as “.smAf” or “.ZITv”, effectively locking the user out of their data. Additionally, it generates a ransom note titled “Decryptfiles.txt” in each affected directory.

Distribution Methods
Edfr789 primarily spreads through malicious spam (malspam) campaigns. Attackers distribute infected email attachments, often in the form of VBScript (.vbs) files, which, when executed, download and install the ransomware onto the victim’s system.
These emails are crafted to appear legitimate, enticing users to open the attachments. Other distribution methods include exploiting vulnerabilities in outdated software, malicious advertisements, and compromised websites.

Technical Analysis
Upon execution, the VBScript creates a folder named “C:\WinXRAR” and downloads malicious executables, such as “Crawl.exe” and “Bootxr.exe”, from remote servers. These executables are then executed using PowerShell commands. The ransomware employs strong encryption algorithms to lock files and appends a unique four-character extension to each encrypted file. It also deletes shadow copies to prevent system recovery, making it challenging for victims to restore their data without external backups.
Ransom Note Details
After encryption, Edfr789 generates a ransom note named “Decryptfiles.txt” in each affected directory. The note informs victims of the encryption and provides instructions for payment to retrieve the decryption key. Victims are urged to contact the attackers within 72 hours to avoid permanent data loss. The provided contact emails are [email protected] and [email protected].
The full content of the ransom note is as follows:
ATTENTION!
Don’t worry, you can return your files! All your files like photos, videos, and other important documents are encrypted with a strong encryption algorithm and unique key. The only method of recovering files is to purchase a decrypt tool and your key. Do not try to recover your files without a decrypt tool; you may damage them, making them impossible to recover.
We advise you to contact us in less than 72 hours; otherwise, there is a possibility that your files will never be returned. We will not wait for your letter for a long time; mail can be abused. We are moving on; hurry up with the decision.
Check your email ‘Spam’ or ‘Junk’ folder if you don’t get an answer within 6 hours.

Detection and Removal
Edfr789 is detected by various antivirus programs under different names. For instance, Avast identifies it as “Win32:MalwareX-gen [Trj]”, ESET-NOD32 as “A Variant Of Win32/Filecoder.ORR”, and Kaspersky as “HEUR:Trojan-Ransom.Win32.Generic”. To remove the ransomware, it’s recommended to use reputable antivirus software to scan and eliminate the malicious files. However, removal of the ransomware does not decrypt the affected files.
Recovery and Prevention
Recovering files encrypted by Edfr789 without paying the ransom is challenging, as no free decryption tools are currently available. Victims are advised not to pay the ransom, as it does not guarantee data recovery and encourages further criminal activity. The best preventive measures include:
- Regular Backups: Maintain up-to-date backups of important data on separate, offline storage devices.
- Email Vigilance: Avoid opening attachments or clicking on links in unsolicited emails, especially from unknown senders.
- System Updates: Keep operating systems and software updated to patch known vulnerabilities.
- Security Software: Use reputable antivirus and anti-malware programs, ensuring they are regularly updated.
- Network Security: Implement firewalls and intrusion detection systems to monitor and protect network traffic.
In case of an infection, it’s crucial to disconnect the affected device from the network to prevent the spread of the ransomware to other systems. Reporting the incident to relevant authorities and seeking assistance from cybersecurity professionals is also recommended.
