Threat Database Ransomware SHTORM Ransomware

SHTORM Ransomware

SHTORM is a type of ransomware that encrypts files on infected computers and demands payment in exchange for a decryption key. The first instances of SHTORM were detected in 2019, and it has since been responsible for numerous attacks worldwide. The SHTORM Ransomware belongs to the Phobos Ransomware family of threats.

How the SHTORM Ransomware Enters a Computer

The SHTORM Ransomware is typically delivered via torrent websites, compromised emails, unsafe advertisements or vulnerabilities in software on the victim's computer. Once installed, it will scan the computer for specific file types to encrypt, such as documents, images, and archives. The encrypted files are renamed with a unique extension, '.SHTORM', and two ransom notes named info.hta and info.txt are left in each folder that contains encrypted files.

The Ransom Note Delivered by the SHTORM Ransomware

The ransom note typically contains instructions on how to pay the ransom, which is usually demanded in Bitcoin or another cryptocurrency. It also provides the means to contact the attackers to negotiate the ransom fee, in this case the addresses (Email), @Stop_24 (Telegram), Tox messenger.

Like other types of ransomware, SHTORM can cause significant disruption and financial losses for businesses and individuals. Therefore, it is essential to take steps to prevent infection, such as keeping software up-to-date, using strong passwords, and being cautious when opening emails and attachments from unknown senders. Additionally, it is recommended to regularly back up crucial files and keep them stored in a secure location in case of a ransomware attack.

How to React in case of an infection with the SHTORM Ransomware

If your computer becomes infected with the SHTORM Ransomware, the first step is to disconnect it from the Internet right away. This will prevent any further spread of the infection and stop additional data from being encrypted. You should also run an anti-malware scan on your system to detect any malicious files that could have been used in the attack.

Once you are sure that your system is no longer connected to the Internet, try to identify which files were encrypted by SHTORM. If possible, back up these encrypted files onto an external storage device or cloud storage service so that you do not lose them completely if you decide not to pay the ransom demand.

You should never attempt to pay a ransom demand as there is no guarantee that you will receive a decryption key or even unlock all your encrypted files after paying. Instead, contact a security expert who can help assess the situation and provide advice on how best to proceed. They may be able to recover your files without paying the ransom.

The following is the info.txt ransom note presented by the SHTORM Ransomware to its victims:
