![]() ![]() To use full-featured product, you have to purchase a license for Combo Cleaner. Our security researchers recommend using Combo Cleaner. To eliminate possible malware infections, scan your computer with legitimate antivirus software. Additional password-stealing trojans and malware infections can be installed together with a ransomware infection. Infected email attachments (macros), torrent websites, malicious ads.Īll files are encrypted and cannot be opened without paying a ransom. Cyber criminals demand payment of a ransom (usually in bitcoins) to unlock your files. A ransom demand message is displayed on your desktop. Text presented in the pop-up window and FILES ENCRYPTED.txtĪvast (Win32:RansomX-gen ), Combo Cleaner (), ESET-NOD32 (A Variant Of Win32/), Kaspersky (), Microsoft (Ransom:Win32/Wadhrama!hoa), Full List Of Detections ( VirusTotal)Ĭannot open files stored on your computer, previously functional files now have a different extension (for example, my.docx.locked). dkey (files are also appended with a unique ID and the cyber criminals' email address) Malware is most widely distributed through: malicious attachments/links in spam emails and messages, online scams, untrustworthy download channels (e.g., unofficial and free file-hosting sites, P2P sharing networks, etc.), illegal software activation ("cracking") tools, fake updates, and malvertising (malicious advertising) Threat Summary: Name Once a malicious file is executed, run, or otherwise opened - malware download/installation processes are jumpstarted. Virulent files can be PDF and Microsoft Office documents, archives (RAR, ZIP, etc.), executables (.exe. Malicious programs are typically disguised as or bundled with ordinary software/media. Malware (ransomware included) is spread using phishing and social engineering tactics. While this software operates practically the same throughout, these programs have two significant differences in-between - the cryptographic algorithms they use ( symmetric or asymmetric) and the ransom size. Solo (VoidCrypt), Tohj, and Lostdata are merely a couple examples of ransomware we have analyzed recently. Hence, we strongly recommend keeping backups in multiple separate locations (e.g., remote servers, unplugged storage devices, etc.) - to ensure data safety. The sole solution is recovering it from a backup (if one is available). However, removal will not restore already compromised data. Therefore, we advise against paying and thus supporting this illegal activity.īy removing ransomware from the operating system - you will prevent it from encrypting more files. Furthermore, victims commonly do not receive the decryption tools - despite meeting the ransom demands. We have analyzed and researched countless ransomware infections, and this experience allows us to conclude that decryption is usually impossible without the cyber criminals' interference. ![]() The message also alerts victims that renaming the encrypted files and/or using third-party decryption tools may result in permanent data loss. This note is concluded with various warnings, from which it is possible to infer that decryption will require paying a ransom. It clarifies that the files have been encrypted. The pop-up window provides more information regarding the ransomware attack. Screenshot of files encrypted by Dkey ransomware:ĭkey's text file merely states that the data has been locked and instructs to email the attackers. For example, a file named " 1.jpg" appeared as " this process was completed, the ransomware displayed a pop-up window and created a text file - " FILES ENCRYPTED.txt" - on the desktop. Original titles were appended with a unique ID, the cyber criminals' email, and a ". Once executed on our test system, Dkey began encrypting files and altering their filenames. It belongs to the Dharma ransomware family, and it is designed to encrypt data and demand payment for decryption. While inspecting new malware submissions to VirusTotal, our researchers came upon the Dkey ransomware-type program. ![]()
