AtomSilo Ransomware

The AtomSilo ransomware emerged in September 2021, the group acts a little differently than other ransomware groups, the ransom amount is fixed, $1 million is charged for the release of the decryption key. If the company makes contact with the group in the first 48 hours that amount can drop by half.

AtomSilo appears to be a variant of the LockFile ransomware because its attacks and structure are identical. Both exploit Proxy Shell vulnerabilities by breaching Microsoft Exchange servers, followed by a PetitPotam NTLM relay attack taking control of the domain, hijacking the Windows API and breaking into the victim’s local computer.

The attack is done through a 16-byte document, something practically unnoticeable to the system, this tactic is called intermittent encryption.

Intermittent encryption aims to avoid detection of ransomware by security programs. It can do this because an encrypted document is similar to the original unencrypted document, making antivirus software unable to detect it.

The encryption of the AtomSilo ransomware is indecipherable, but still, with the right company the recovery of the encrypted data is possible. Digital Recovery is capable of recovering such files.

The AtomSilo group, according to its websites, has already attacked hospitals, critical infrastructure facilities, oil and gas industry, educational facilities and also non-profit companies.
