ITSA ransomware is a newly identified file-encrypting malware strain that appends the “.itsa” extension to compromised files and demands a ransom in exchange for the decryption key. It targets a wide range of personal and system files, rendering them inaccessible to the victim. After encryption, a ransom note named “Decryption Instructions.txt” is dropped, instructing the victim to contact the attackers through ventutusa@gmail.com.
Threat Overview
ITSA ransomware is a typical crypto-virus that uses strong encryption to lock files on the infected system. Victims are unable to access any of their important documents, media, or work files unless they pay the ransom, which may or may not result in file recovery. This ransomware can enter systems through various deceptive tactics and can cause substantial data loss.

In-Depth Analysis
How Did I Get Infected?
ITSA ransomware typically spreads through:
- Malicious spam emails containing infected attachments
- Software cracks or keygens downloaded from shady sites
- Fake software updates or installers
- Malicious advertisements and compromised websites
Once the malware is executed, it silently runs in the background, encrypting files and then notifying the victim via a ransom note.
What Does It Do?
After infecting a system, ITSA ransomware:
- Encrypts a wide range of file types and appends the
.itsa
extension - Drops a ransom note named “Decryption Instructions.txt”
- Demands that the victim contact ventutusa@gmail.com for payment instructions
- Warns users not to rename or modify files to avoid permanent damage
There is no publicly available decryptor for this ransomware as of now.
Should You Be Worried?
Absolutely. ITSA ransomware can lead to permanent loss of personal data, business documents, and critical system files. Even if you consider paying the ransom, there’s no guarantee of recovering your data, and it only encourages further criminal activity. It’s essential to remove the malware immediately using trusted security software and avoid reinfection by tightening cybersecurity practices.
