Typically, they disguise their emails as important or official and seek to trick recipients into opening (executing) the attached file. #Bitmessage ch pdfCyber criminals who use spam campaigns send emails with malicious files attached to them.įor example, MS Office, PDF documents, archive files such as ZIP, RAR, executable files such as. Some of the most commonly used ways to proliferate malware are spam campaigns, untrustworthy software download sources, unofficial activation ('cracking') tools, fake updaters and Trojans. This is rare and, therefore, it is important to have data backed up and stored on a remote server (e.g. Therefore, it is impossible to decrypt files without having to pay the ransom, unless the ransomware is not finished (contains bugs/flaws, and so on). As mentioned, only the cyber criminals who designed the ransomware have the tools to decrypt files. The two main differences are usually cost of decryption and cryptographic algorithm ( symmetric or asymmetric) used to lock (encrypt) data. More examples of software classified as ransomware include Mbed, SySS, and SpartCrypt. Typically, malware of this type encrypts files and creates and/or displays a ransom message that contains instructions about how contact the developers, pay the ransom, etc. Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data: Removing ransomware from the operating system simply prevents it from causing further encryption. Generally, the only way to recover files without being scammed is to restore them from a backup.Įven if ransomware is uninstalled, encrypted files remain encrypted. Victims who pay the ransom are often scammed and receive no decryption tools or keys. Typically, only the ransomware developers can allow victims to decrypt their files, however, they should never be trusted. They can be contacted by sending an email to or can attach one encrypted file to 'prove' that Kodg's developers have valid tools to decrypt files (they will decrypt and return the file free of charge). In this way, they encourage victims to contact them as early as possible after infection. These can be purchased from the developers of Kodg for $980, however, victims who contact them within 72 hours of encryption are offered a 50% discount. The ransom message (within "_readme.txt") states that the only way to recover files is to decrypt them with a specific tool and unique key. ![]() It also creates a ransom message within the " _readme.txt" text file. ![]() For example, " 1.jpg" becomes " 1.jpg.kodg". kodg" extension to the name of each encrypted file. Therefore, victims are encouraged to pay ransoms. ![]() Software of this type is generally encrypts data so that victims cannot decrypt or access it without specific tools/keys, which must be purchased from the cyber criminals who designed the program. Discovered by Michael Gillespie, Kodg is one of many ransomware-type programs that are part of the Djvu ransomware family. ![]()
