![]() The attachments and links present in suspect/irrelevant emails and messages - must not be opened, as that may lead to a system infection.įurthermore, all downloads must be performed from official/verified channels. We recommend exercising caution with incoming mail. ![]() How to protect yourself from ransomware infections? Combo Cleaner is owned and operated by Rcs Lt, the parent company of read more. 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. Threat Summary: NameĪvast (Win32:Malware-gen), Combo Cleaner (Trojan.GenericKD.39834878), ESET-NOD32 ( A Variant Of Win32/Filecoder.OLN), Kaspersky (HEUR:), Microsoft (Ransom:Win32/Crypmodng!mclg), 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). The most common distribution methods include: drive-by (stealthy and deceptive) downloads, malicious attachments and links in spam emails/messages, dubious download channels (e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc.), online scams, fake updates, and illegal software activation tools ("cracks"). Once such a file is executed, run, or otherwise opened - malware download/installation is initiated. run, etc.), archives (ZIP, RAR, etc.), Microsoft Office and PDF documents, JavaScript, and so on. ![]() Malicious programs are typically disguised as or bundled with ordinary software/media. Malware (ransomware included) is mainly proliferated using phishing and social engineering techniques. This malicious software operates practically identically throughout however, these programs have two major differences in-between - the cryptographic algorithms they use ( symmetric or asymmetric) and the ransom size. We have analyzed countless ransomware samples Oiltraffic, Cceo, World2022decoding, Daz, and Ccza are merely some of our newest finds. Hence, we strongly recommend keeping backups in several different locations (e.g., unplugged storage devices, remote servers, etc.) - to ensure data safety. The only solution is recovering the files from a backup (if one is available). Unfortunately, removal will not restore already compromised data. Removing PLAY ransomware from the operating system will prevent it from further encryptions. Therefore, we advise against paying and thus inadvertently supporting this illegal activity. ![]() Furthermore, victims often do not receive the necessary tools to decrypt their data - despite meeting the criminals' demands. The note consists of the program's name (PLAY) and the attackers' email address (which may vary depending on the variant).īased on our extensive experience researching ransomware infections, we can conclude that decryption is usually impossible without the cyber criminals' involvement. This message does not inform victims of the data encryption, state the ransom size, or give payment instructions. PLAY's message does not provide the standard information for ransom notes. Screenshot of files encrypted by PLAY ransomware: Once the encryption process was completed, PLAY created a text file named " ReadMe.txt" on the desktop. For example, a file titled " 1.jpg" appeared as " 1.jpg.PLAY", " 2.png" as " 2.png.PLAY", etc. Malware categorized as such operates by encrypting data and demanding ransoms for the decryption.Īfter we executed a sample of this ransomware on our test machine, it encrypted files and appended their filenames with a ". PLAY is the name of a ransomware-type program. ![]()
