About Mamba Ransomware

Mamba ransomware can be compared with Petya ransomware, since both use disk encryption strategy. Though Petya virus encrypts the MFT (master file table), instead of the data itself. As opposed to this, Mamba virus utilizes an open source tool DiscCryptor to encrypt the actual data with the popular asymmetric algorithm. When the targeted disk has been encrypted, Mamba crypto-malware displays the ransom note on the lock screen:

The only concrete information the message of Mamba file-encrypter contains is the contact e-mail address – w889901665@yandex.com – which is to be used to contact these hackers. The size of the ransom has been reported to be 1 BTC (bitcoins – the cyber currency), amounting to 607,07 USD at this particular point in time. Though the official decryptor has not been released yet, the affected users are forewarned not to pay the money demanded for and not to try to get in touch with these cyber criminals in the first place, as the consequences can be even more sad.

Mamba encoder is a Trojan Horse, getting into the victim’s computer by stealth. Its name perfectly reflects its serpentine nature. This crypto virus is inhabited in the spam e-mails, sent to the victim. These spam e-mails, typically, contain fake notifications pretending to be sent by the existing institutions or companies, local or international ones.

If the user clicks on any of the links provided or opens any of the attachments appended, the payload of Mamba encryptor, namely, 152.exe or 141.exe files, start to be executed, which means that his (her) PC has already been infected. Mamba trojan virus can also be the result of careless visiting of suspicious sites or careless clicking on suspicious advertisements.
