![]() ![]() Fake software updaters can infect systems by exploiting bugs/flaws of outdated software, or simply by installing malware rather than updates. They send emails that are disguised as important and official, and hope that recipients open the attached file, or a file downloaded through an included website link.Įxamples of files that they usually attach are Microsoft Office documents, PDF documents, archive files such as ZIP, RAR, executable files (.exe) and JavaScript files. In most cases, computers become infected with ransomware and other malicious software through spam campaigns, fake software updaters, untrusted file and/or software download sources, unofficial software activation tools and Trojans.Ĭyber criminals attempt to trick people into installing malware through malicious files that they attach to their emails. Therefore, maintain backups on a remote server (such as Cloud) and/or unplugged storage device. Some examples of other ransomware include Baraka Team, Tsar and Happychoose. Typically, it is impossible to decrypt files without specific tools held only by cyber criminals, unless (in rare cases) the ransomware contains bugs/flaws or is still in development. Main variables are cost of a decryption tool and cryptographic algorithm ( symmetric or asymmetric) that ransomware uses to lock data. Generally, software of this type encrypts data and keeps it inaccessible unless victims purchase tools/keys from the cyber criminals who designed the ransomware. Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data: Note that files remain encrypted even after removal of ransomware - removal from the operating system simply prevents it from causing further encryption. In such cases, the only way to recover files without having to use tools purchased from cyber criminals is to restore them from a backup. Therefore, DEMON's developers should not be trusted. Victims who pay are often scammed - they receive no decryption tools or keys. Unfortunately, in most cases, the only people who have these tools are the cyber criminals who designed the ransomware.ĭespite this, never trust them or pay the ransom. For more details, victims are urged to contact these cyber criminals by sending an email to ransomware-type programs encrypt files with strong encryption algorithms, and it is impossible to recover them without the correct decryption tools. It is also mentioned that unless the transaction is made within 600 minutes (10 hours), all of the victim's data will be destroyed and/or sold to third parties. ![]() Victims must pay $10,000 in Bitcoins by transferring cryptocurrency to the BTC wallet address provided. ![]() The ransom messages (text file and pop-up window) state that DEMON encrypts all data, and the only way to recover them is to pay a ransom. It also drops the " README.txt" text file (containing the ransom message) in all folders that contain encrypted files. DEMON" extension to filenames.įor example, " 1.jpg" is renamed to " 1.jpg.DEMON" and so on. DEMON renames encrypted files by appending the ". This malicious software encrypts files, renames them, creates a ransom message and displays another in a pop-up window. DEMON ransomware was discovered by GrujaRS. ![]()
