If your files have been encrypted, we accept the challenge of analyzing your case.

Ransomware AtomSilo

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 within the first 48 hours this 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 via a 16-byte document, which is barely noticeable to the system, this tactic is called intermittent encryption.

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

The encryption of the AtomSilo ransomware is indecipherable, but still, with the right company the recovery of 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, the oil and gas industry, educational facilities, and also non-profit companies.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.

Ransomware is designed to be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

Yes, it is possible. You can restart the computer in safe mode which will limit the ransomware’s action as system resources will be locked. You can also disconnect the computer from the Internet which can interrupt the hackers’ connection to your system, it is worth remembering that there is ransomware that works even without being connected to the Internet. You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses have this function.
But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and even the hackers could not restore the files, even with the decryption key. In these cases only a data recovery company, such as Digital Recovery, can recover the files.

Yes, attacks usually happen mainly on holidays and weekends during the early morning hours. These days are chosen because there are not many active users on the system, which prevents the attack from being discovered before the encryption is completed.

The vast majority of ransomware uses RSA [Rivest-Shamir-Adleman]-2048 and AES [Advanced Encryption Standard] encryption.
