Blassa Ransomware: A Comprehensive Overview and Removal Guide

Ransomware is a type of malicious software (malware) that encrypts files on a victim’s computer, rendering them inaccessible until a ransom is paid. This form of cyber extortion has become increasingly prevalent, with new variants emerging regularly. One such threat is Blassa ransomware, which poses significant risks to individual users and organizations alike. This article delves into the specifics of Blassa ransomware, its operation, consequences, and how to effectively remove it from infected systems.

The Threat of Blassa Ransomware

Blassa ransomware targets Windows-based systems. It infiltrates computers through various means, often utilizing phishing emails, malicious downloads, or vulnerabilities in outdated software. Once installed, Blassa executes a series of actions that lead to the encryption of personal files.

After successfully infiltrating a system, Blassa scans for common file types—such as documents, images, and videos—and encrypts them using a robust encryption algorithm. Files are typically renamed with a specific extension, for example, “.blassa.” This means that a file originally named “important_document.docx” may become “important_document.docx.blassa” after encryption.

The consequences of Blassa’s presence on a system are severe. Users may find their essential files, including documents, photos, and databases, rendered unusable. This can lead to significant data loss and disruption of daily activities, both for individuals and businesses. In the case of Blassa, the ransomware leaves a ransom note, typically in the form of a text file, providing instructions on how to pay the ransom in exchange for the decryption key.

Ransom Note Overview

The ransom note left by Blassa, RESTORES_FILESDESKTOP-[random_string].tx, serves as a critical communication tool between the attackers and the victims. It usually contains details about the ransom amount, payment methods (often in cryptocurrencies like Bitcoin), and a deadline for payment. Failure to comply may result in the permanent loss of access to the encrypted files. The note also frequently includes threats of data publication or further actions if the ransom is not paid, heightening the pressure on the victim.

Text of the ransom note:

*BLASSA RANSOMWARE**
Oops, sorry, your file has been stolen and we have temporarily encrypted it
using very strong military encryption techniques.
You don’t need to worry because once again ‘this is only temporary’
and it is impossible to return and open it without using my key.
If you want to recover or reopen your locked files,
you need to open them using my key.
To get the key from me you can buy with price $400.

Attention :
1. Never negotiate with the police or any legal party.
2. Never report this to the police or legal authorities,
because obviously they will not provide any solution.
3. Never change the file extension or modify the file to restore it yourself,
because this can damage the file so that the file cannot be recovered later.
4. Never delete the files part of the ransomware before being given the key to open it,
because it can also damage the files so that the files cannot be recovered
