What is Cr1ptT0r Ransomware

Cr1ptT0r Ransomware is new type of ransomware, that uses network disk array vulnerability to infect user’s computers. This crypto ransomware encrypts data on network (cloud, NAS, Network Attached Storage) storage using a special encryption algorithm, and then requires a ransom of ~ 0.3 BTC to return files. Original title Cr1ptT0r is indicated in the ransom note and on the page on the OpenBazaar website. Developers call themselves a Cr1ptT0r team. The ELF ARM binary is used for Linux systems with a focus on embedded devices, but depending on the manufacturer it can be adapted for Windows. Ransomware does not append any extension, but uses _Cr1ptT0r_ file marker instead. Virus creates 2 files: _FILES_ENCRYPTED_README.txt and _cr1ptt0r_support.txt. First one is ransom note, that contains following message:

The Sodium crypto library and the asymmetric encryption algorithm “curve25519xsalsa20poly1305” (Curve25519, Salsa20, Poly1305) are used for encryption. The open 256-bit encryption key is located in the cr1ptt0r_logs.txt file, which also stores the list of encrypted files, and it is also added to the end of the encrypted files, just before the marker. Cr1ptT0r Ransomware uses the OpenBazaar site to “support” the affected users and selling the decoder. There are no decryption tool available yet, however, using instructions in this article can help you recover encrypted files.

How Cr1ptT0r Ransomware infected your PC

Victims used the D-Link NAS DNS-320. If you have such a device model or close to it, then all models in the default settings contain the vulnerability that the attackers used. At the time of this writing, there was no information about which particular vulnerability was used. But it must be recalled that older models with outdated firmware are more vulnerable than those that received an update. We recommend you update your NAS device using this links: DNS-320 and DNS-320L. Virus can be also distributed by hacking through an unprotected RDP configuration, using email spam and malicious attachments, deceptive downloads, botnets, exploits, web injections, fake updates, repackaged and infected installers. Virus assigns certain ID with the victims, that is used to name those files and supposedly to send decryption key. In order to prevent infection with this type of threats in future we recommend you to use Norton Antivirus, SpyHunter 5, BitDefender or any reputable antivirus program.
