JustIce (also styled as Just Ice) is a dangerous ransomware variant that encrypts user files and demands payment for their recovery. First spotted in July 2025, this file-locking malware appends the .JustIce extension to encrypted files and drops a ransom note named README.txt. Victims are instructed to contact the attackers via a provided email address and pay in cryptocurrency to regain access to their data.

Threat Evaluation & Analysis
How did I get infected?
Infections typically occur when a user unknowingly opens a malicious email attachment, downloads pirated software, falls for fake tech-support alerts, visits compromised torrent platforms, clicks on malicious ads, or connects an infected USB drive. These attack vectors enable the ransomware to silently infiltrate systems and begin its encryption routine.
What does it do?
JustIce ransomware silently encrypts files across the system, modifying filenames with the .JustIce extension. It leaves a ransom note demanding payment and alters the desktop wallpaper to reinforce the threat. The malware disables file access and may also be part of a broader attack, potentially installing secondary payloads or spyware.
Should you be worried for your system?
Yes. JustIce can cause irreversible damage by locking access to important files and pressuring victims into paying large sums of cryptocurrency. There’s no guarantee the attackers will deliver the decryption key, and payment only encourages more attacks. The presence of JustIce also increases the likelihood of further system compromise through backdoors or data harvesting.
