What is Blackoutware Ransomware?

Blackoutware (.blo) is a type of malicious software designed to encrypt files2 on a victim’s computer, rendering them inaccessible. It is named for its distinctive file extension, .blo, which it appends to encrypted files. The ransomware operates by infiltrating computer systems, encrypting files, and then demanding a ransom, typically in cryptocurrency, for the decryption key.

The mechanism of Blackoutware involves sophisticated encryption algorithms that lock files, including documents, images, and system files. It often targets not just individual files but entire systems, making it particularly disruptive.

Blackoutware ransomware, upon infecting a system, encrypts files and modifies their names by adding a “.blo” extension. Consequently, files like “1.jpg” and “2.png” are renamed to “1.jpg.blo” and “2.png.blo,” respectively. After completing the encryption, the ransomware leaves a ransom note named “!!!WARNING!!!.txt” in the directory “C:\Users[username]”, signaling the end of its encryption process.

Methods of Blackoutware Spread

Blackoutware primarily spreads through:

  • Phishing Emails: These are deceptive emails that trick users into downloading an attachment or clicking a link that installs the ransomware.
  • Malicious Downloads: Downloading software from unverified sources can result in the inadvertent installation of Blackoutware.
  • Exploitation of Software Vulnerabilities: Unpatched software can be an entry point for this ransomware.

Recent attacks have shown that Blackoutware authors continuously evolve their tactics, often using social engineering and exploiting the latest software vulnerabilities.

Recognizing a Blackoutware Infection

Key indicators of a Blackoutware infection include:

  • Changed File Extensions: Files end with the .blo extension.
  • Ransom Notes: A message usually appears on the user’s screen or within affected directories, explaining the encryption and demanding payment.
  • Inaccessible Files: Encrypted files cannot be opened with standard software.

What To Do First When Infected With Blackoutware Virus?

Ransomware like Blackoutware can spread to external storage devices and local networks, making immediate isolation of the infected device critical.

Step 1: Disconnect from the Internet

Quickly disconnecting your computer from the internet is crucial to prevent the spread of the ransomware to your device and personal files.

For Wired Connections: Physically unplug the Ethernet cable from the motherboard.

For Wireless Connections: If you’re using Wi-Fi or find handling cables challenging:

  • Go to the “Control Panel.”
  • In the search bar, type “Network and Sharing Center” and select it.
Search for Network and Sharing Center
  • Click on “Change adapter settings” in the window.
Change adapter settings
  • Right-click on each connection and select “Disable.” To reconnect later, right-click and select “Enable.”
Disable connection point

Step 2: Unplug All Storage Devices

External storage devices connected to your computer might also be at risk of the blackoutware virus. Eject each device properly to avoid data corruption:

  • Go to “My Computer.”
  • Right-click on each connected device and select “Eject.”
Unplug All Storage Devices

Step 3: Log Out of Cloud Storage Accounts

Logout all cloud storages

Ransomware can access cloud-stored data. Log out from all cloud storage accounts on browsers and related applications. Consider uninstalling cloud-management software until the infection is fully resolved.

Identifying the Ransomware Infection & Removing It

Accurate identification of the ransomware is crucial for effective response and recovery of your operating system and device. Let’s see how you can identify if this is really Blackoutware and remove it.

Step 1: Examine Ransom Messages

Examine Ransom Messages

Ransomware typically leaves a note demanding payment, often with generic filenames like “_readme.txt” or “DECRYPTION_INSTRUCTIONS.txt.” However, reliance solely on the file name may be misleading due to the generic nature of these names.

This is how the extortion text might look like:

“Hello All your files are encrypted by Blackoutware.
For decryption Send 5000€ LTC or BTC to The Wallet Mentioned At the Bottom of the Text
And Email us with the Transaction ID And ID We Will Give u the Decryptor
BTC Address: bc1q265exqnphfd99a2v00yzd87mz6kjpqkylk2cv3
LTC Address: Lh9PRuQsnwJcvAJCvJ9e7iNh6nueFCnXvf

[+] Do not delete This Text File
[+] Do not rename encrypted files.
[+] Do not try to decrypt your data using third party software, it may cause permanent data loss.
[+] You have 72 hours to get the key.”

Step 2: Check the File Extensions

Check File Extensions

Examine the extension appended to encrypted files. Unique extensions can help identify the ransomware strain, while generic extensions like “.encrypted” make identification more challenging.

Step 3: Use Online Identification Tools

Use Online Identification Tools

There are online tools that can help identify the ransomware in your email attachments, external hard drives, and even your audio files. They can provide details like the malware family name and decryption possibilities after doing a full scan of your files and folders.

Step 4: Internet Research to Identify Your Ransomware (Is it really blackoutware?)

Internet Research

If those tools don’t show good results, use search engines with keywords from the ransom note, file extension, or provided contact information.

We also recommend visiting ID Ransomware website where you can upload your infected file or ransom note and identify the virus accurately.

Searching for Blackoutware Decryption Tools & Removing the Virus

Most high-end ransomware uses complex encryption algorithms, making decryption without the original key almost impossible. However, some ransomware strains are poorly designed with flaws like identical keys for all victims or locally stored keys.

Always search for decryption tools specific to the ransomware that infected your computer.
We recommend visiting the NoMoreRansom project and downloading a tool that’s specifically developed for the ransomware that infected your PC.

After you successfully confirmed that this is blakcoutware virus — you should download the decryption tool from NoMoreRansom mentioned above and try removing the virus.
