Basta (Makop) Ransomware

A recent incident showcased a mid-sized enterprise crippled by unexpected file encryption: documents, images, and databases rendered inaccessible overnight. This attack traced back to a new variant of the Makop family, dubbed “Basta”, which appends a unique identifier and the “.basta” extension to each file. Victims awaken to find critical systems locked and a ransom demand waiting on their desktops, underscoring the urgency of swift detection and removal.

Threat Overview

Ransomware encrypts user files, rendering them unusable until a ransom is paid. Basta targets a wide range of file types—documents, images, databases—and appends the “.basta” extension along with the victim’s ID and attacker email. As part of the Makop family, it combines strong encryption with data theft threats, warning that stolen files will be compromised if demands remain unmet.

In-Depth Analysis

Infection Vector

Basta often arrives via spear-phishing emails carrying malicious attachments or links. It also exploits trojanized installers for pirated applications and infiltrates through deceptive ads and compromised websites. Once executed, the payload initiates file encryption routines and communicates with command-and-control servers.

Behavioral Profile

1. Initialization: Creates persistence entries in Windows Registry.
2. Encryption: Scans for targeted file extensions, encrypts them with AES/RSA methods, and renames files to include the victim’s ID and “.basta” extension.
3. Ransom Note Deployment: Places a “+README-WARNING+.txt” note on the desktop and in encrypted directories.
4. Data Exfiltration: Transmits copies of encrypted files to the attacker’s server, leveraging anonymity networks if configured.

Risk Assessment

Basta’s dual-threat—encryption and theft—elevates its impact above standard crypto-viruses. During the 2018 WannaCry outbreak, compromised backups led to prolonged downtime; with Basta’s data exfiltration, victims face extortion on two fronts. Organizations lacking immutable backups or network segmentation stand at highest risk, making early detection and response critical.

3. Right-click on the process and select End Task.

For Mac Users:

1. Open Activity Monitor (Finder > Applications > Utilities > Activity Monitor).
2. Look for unusual processes.
3. Select the process and click Force Quit.

Step 4: Delete Malicious Files

For Windows Users:

1. Press Windows + R, type %temp%, and hit Enter.
2. Delete all files in the Temp folder.
3. Navigate to:
   • C:\Users\[Your Username]\AppData\Roaming
   • C:\Users\[Your Username]\AppData\Local
   • C:\Windows\System32
4. Look for suspicious files related to the ransomware (random file names, recently modified) and delete them.

For Mac Users:

1. Open Finder and go to Go > Go to Folder.
2. Type ~/Library/Application Support and delete suspicious folders.
3. Navigate to ~/Library/LaunchAgents and remove unknown .plist files.

Step 5: Remove Ransomware from Registry or System Settings

For Windows Users:

Warning: Incorrect changes in the Registry Editor can damage your system. Proceed with caution.

1. Press Windows + R, type regedit, and hit Enter.
2. Navigate to:
   • HKEY_CURRENT_USER\Software
   • HKEY_LOCAL_MACHINE\Software
3. Look for unfamiliar folders with random characters or ransomware-related names.
4. Right-click and select Delete.

For Mac Users:

1. Go to System Preferences > Users & Groups.
2. Click on Login Items and remove any suspicious startup items.
3. Navigate to ~/Library/Preferences and remove malicious .plist files.
