Threat Database Ransomware Spydr Ransomware

Spydr Ransomware

The Spydr Ransomware is a threatening malware designed to lock specific files and render them inaccessible and unusable. The threat achieves its nefarious goal via an encryption routine with a strong cryptographic algorithm. The attackers then extort their victims for money by promising to send the required decryption key and software tool afterward getting paid. Analysis has determined that the Spydr Ransomware is a variant of a previously detected threat named Babuk.

As part of its encryption process, the threat will append '.spydr' to the names of all affected files as a new file extension. A lengthy ransom note will be delivered to compromised systems as a text file named 'RESTORE FILES.txt.'

Ransom Note's Overview

According to the note, affected users will have to pay a ransom using the Bitcoin cryptocurrency, if they want to receive the decryptor tool from the attackers. The exact sum demanded by the hackers is not mentioned but, apparently, victims will receive a discount if they establish contact within the first two days of the ransomware infection. The note provides two email addresses that may be used for communication - '' and '

As part of their message, affected users are allowed to send two files that will be unlocked for free and returned. The files, however, must have simple extensions (jpg, Xls, doc, but no databases) and should be less than 1 MB in size.
