What is Synapse Ransomware

Synapse Ransomware is a type of malware that encrypts data on infected computers, demanding payment for decryption. It was first discovered in February 2024 and operates as a Ransomware-as-a-Service (RaaS), indicating a structured distribution model where affiliates deploy the ransomware while the developers receive a share of the ransom payments. Once Synapse ransomware infects a computer, it encrypts files using robust cryptographic algorithms including RSA-4096, AES-256, and ChaCha20. This encryption is virtually unbreakable without the decryption key held by the attackers. The ransomware appends a .Synapse extension to the encrypted files, altering their original names to a random character string, which makes them easily recognizable. After encrypting the files, Synapse ransomware drops a ransom note named [random_string].README.txt on the victim’s desktop. This note explains that the files have been encrypted and provides instructions for payment, typically demanding payment in cryptocurrencies like Bitcoin. The note may also offer to decrypt one file for free as proof that the attackers can restore the files.

As of the latest updates, there are no free decryption tools available that can decrypt files affected by Synapse Ransomware. This is due to the strong encryption algorithms used, which do not currently have vulnerabilities that would allow third parties to break the encryption without the specific decryption key. Given the lack of a reliable decryption tool, the recommended approach for recovery is to restore the affected files from backups. Victims should first remove the ransomware from their computer using a reputable malware removal tool to prevent further encryption. Following this, files can be restored from backups that were not connected to the network at the time of infection.

How Synapse Ransomware infects computers

Synapse Ransomware primarily infects computers through various vectors:

Phishing Emails: These emails contain malicious attachments or links that, when opened, execute the ransomware.
Exploit Kits: These are tools that exploit vulnerabilities in software on the victim’s computer to install ransomware.
Malicious Advertisements: Also known as “malvertising,” this method involves embedding malware in online advertisements.
Pirated Software: Downloading and installing pirated software can also lead to ransomware infections, as these often contain malicious additions.
