Sambo Ransomware

Posted: April 23, 2019

The Sambo Ransomware is a file-locking Trojan that can block media like documents on your computer. Its attacks include appending e-mail addresses and 'sambo' extensions onto your files' names, changing your wallpaper, and delivering ransoming messages for an unlocker. Users can always back their work up securely for protection against infections and should depend on anti-malware solutions for finding or removing the Sambo Ransomware.

Little Black Trojans in a Criminal's Paradise

Trojans from the Paradise Ransomware family are including apparent racial literary references in their campaigns that line up with their current regions of attack. The Sambo Ransomware, a possible reference to the Indian pickaninny-illustrated stories featuring a protagonist of the same name, is circulating throughout India and may be using infection methods that are specific to that country's user currently. However, its encryption, like those of its less-inflammatory relatives like the Recognizer Ransomware, 'the .securityP File Extension' Ransomware, the 'babyfromparadise666@gmail.com' Ransomware, and the Yourencrypter@protonmail.ch Ransomware, is mostly universal.

Besides requiring Windows environments, the Sambo Ransomware is compatible with most systems and includes a payload with file-locking properties. Because its routine uses RSA as a primary encryption method, it can take longer than most file-locker Trojan s for completing its attacks, which encrypt documents and other files, one by one, and changes their names with the 'sambo' extensions and the threat actor's e-mail address. It also uses a second layer of RSA for guaranteeing the attack's security from any third-party decryption.

Related symptoms that users can employ for identifying the Sambo Ransomware infections afterward include:

  • The absence of the Shadow Volume Copy backup information, which the Sambo Ransomware deletes.
  • Wallpaper changes that reset your desktop's background to a warning message.
  • File-restoration instructions that come in two formats, from the 'Paradise Ransomware Team.'

Real-World Solutions to Storybook Trojans

It seems too improbably a coincidence that the Sambo Ransomware's choice of extension matches with the nationality of its victims so well. Threat actors could be seeding India-specific torrents, sending spam e-mails to previously-harvested Indian accounts, or using Web content targeting that region, such as malvertising. As always, Ransomware-as-a-Service's structure makes perfect predictions of all the strategies putting victims at risk impossible.

Users who interrupt the Sambo Ransomware's attacks before they finish may be capable of recovering some or all of their files from Windows' default solutions, although this isn't very likely. Malware experts recommend avoiding dealing with the ransoming service of criminals, when possible, and keeping secure backups of your files for retrieving when necessary. Most anti-malware products should provide adequate protection by stopping and removing the Sambo Ransomware immediately.

Whether the Sambo Ransomware is the presumed literary reference or not, it's another attack against users with files as collateral. The only paradisical part of Paradise Ransomware's offspring is the money it funnels to criminals, which is a garden that the no PC owner should help flourish.
