New Botnet Dubbed Kraken Deploys Backdoor to Steal Sensitive Information from Windows Hosts

The cybersecurity researchers at ZeroFox Intelligence have recently discovered a new Golang-based botnet which is dubbed Kraken. This new botnet is under active development and exploited by the threat actors to deploy backdoors to steal sensitive data from the Windows hosts.

Initially, this botnet, Kraken has been detected in late October 2021 and after its visibility, it’s been discovered that the early variants of the Kraken botnet are based on open source code that was uploaded to GitHub.

However, after the detection, it’s not clear yet whether the GitHub profile where the early variants were uploaded belongs to operators of the Kraken botnet or the code was used to kickstart their development only.

Abilities of Kraken

On further analysis, it’s been identified that the Kraken botnet offers some certain key features and abilities, and here we have mentioned all of them below:-

  • Download secondary payloads on the compromised system.
  • Execute secondary payloads on the compromised system.
  • Run shell commands on the victim’s system.
  • Take screenshots of the victim’s system.
  • Collect information about the host for registration (varies per version).
  • Maintain persistence on the victim’s system.
  • Steal various cryptocurrency wallets.

Infection Vector

Since Kraken uses SmokeLoader to install other malicious software, so, the operators of Kraken easily spread this botnet in self-extracting RAR SFX files that are downloaded with the help of SmokeLoader malware.

While the self-extracting RAR SFX files contain the following ingredients:-

  • A UPX-packed version of Kraken.
  • RedLine Stealer.
  • A binary that is used to delete Kraken. 

Apart from this, currently, the SmokerLoader malware directly downloads the current version of the Kraken botnet, and here all the Kraken binaries that are UPX-packed remain protected by the Themida packer.

Wallets targeted

Here we have mentioned below all the crypto wallets targeted by the Kraken botnet:-

  • Armory
  • Atomic Wallet
  • Bytecoin
  • Electrum
  • Exodus
  • Guarda
  • Jaxx Liberty
  • Zcash

Here’s what the cybersecurity analysts at ZeroFox Intel have stated:-

“It is currently unknown what the operator intends to do with the stolen credentials that have been collected or what the end goal is for creating this new botnet.”


The security researchers have mentioned some recommendations and here we have mentioned them below:-

  • Use robust security systems and AV tools.
  • Keep your system and software updated.
  • Enable two-factor authentication.
  • Regularly check and take offline backup of your data.
  • Be cautious before opening any unknown attachments received in the email.
  • Do not click on suspicious links.
  • Always monitor and review the system and network logs.
