How to remove Blackoutware Ransomware and decrypt .blo files

What is Blackoutware Ransomware

Blackoutware is a type of ransomware, a malicious software designed to encrypt data and demand ransoms for its decryption. This article will provide a comprehensive understanding of Blackoutware Ransomware, its infection methods, the file extensions it adds, the encryption it uses, the ransom note it creates, and the potential decryption tools available. Blackoutware Ransomware is a crypto virus that encrypts files on a victim’s computer and appends their filenames with a .blo extension. For instance, a file initially titled 1.jpg would appear as 1.jpg.blo. After the encryption process, a ransom note titled !!!WARNING!!!.txt is dropped into the C:\Users[username] folder. The ransom note states that the victim’s files have been encrypted and that decryption requires payment. The ransom is typically demanded in cryptocurrencies, such as Litecoin (LTC) or Bitcoin (BTC), with the amount often listed as 5000 euros. The victim is usually given 72 hours to comply, and the note warns against modifying the encrypted files or using third-party decryption tools, as this could result in permanent data loss.

Ransomware typically uses strong encryption algorithms, such as AES or RSA, to lock the victim’s files. Once encrypted, the files can only be unlocked by a decryption code known only to the attacker. As of the current date, there are no specific decryption tools available for Blackoutware ransomware. However, organizations like Avast, AVG, Emsisoft, Kaspersky, and Trend Micro offer free ransomware decryption tools for some of the most common types of ransomware. It’s important to note that these tools may only work with specific ransomware versions and may not work with versions released after a tool was created

Since there are no specific decryption tools for Blackoutware, decrypting .blo files can be challenging. However, anti-malware designers are constantly working on creating decryption tools, and an effective countermeasure may soon be available. In the meantime, victims are advised not to pay the ransom, as this does not guarantee the recovery of the encrypted files and only encourages the attackers. Instead, victims should report the incident to their local authorities and seek professional help.

How Blackoutware Ransomware infects computers

Ransomware like Blackoutware is primarily spread using phishing and social engineering techniques. Malicious programs are often disguised as or bundled with ordinary software or media files, such as archives (RAR, ZIP), executables (.exe, .run), documents (Microsoft Office, Microsoft OneNote, PDF), JavaScript, and more. Once such a file is opened, the infection chain is triggered. Some malicious programs can even self-spread via local networks and removable storage devices, such as USB flash drives and external hard drives.
