Threat Behavior of Darus Ransomware Alike its siblings, Darus Ransomware has been developed to generate illicit revenue by extorting ransom from the victims of .Darus file virus. The attack of Darus begins with common internet services. Some of the spread channels employed by the hackers include spam e-mail campaigns, unreliable software download sources, torrent websites & fraudulent online advertising. Upon entering the system, Darus scans the infected system for targeted user & system files. When found, it encrypts them with RAS (Rivest–Shamir–Adleman) & AES (Advanced Encryption Standard) Encryption methods. These cryptographies are highly-complex. They also generate a unique private decryption key for each infected user & store them on the hacker-controlled server. The encrypted files are renamed with .Darus extension & hence, instantly made unusable to the victims. A file “image.jpg” might be renamed as “image.jpg.darus” after the encryption. The file extensions that are at the target of the Darus Ransomware include: Document files (.docx, .doc, .odt, .rtf, .text, .pdf, .htm, .ppt) Audio Files (.mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa, .wma, .ra, .avi, .mov, .mp4) Video Files (.3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob) Images (.jpg, .jpeg, .raw, .tif, .gif, .png) Backup Files (.bck, .bckp, .tmp, .gho) Insight into the Ransom Note & Amount Demanded by Hackers Following the successful encryption, it drops a ransom-demanding message in every folder than contains Darus infected files. This ransom note is in text format & named “_readme.txt”. The ransom note appears every time a victim tries to access the encrypted file. It contains the present situation of the system & certain instructions to the victims. The note conveys that decryption of data is not possible without hacker’s interference. The restoration of data requires a unique private key & Darus decrypter that is stored on the hacker’s server. To purchase the Darus decryption tool & key, the victim must contact the hackers on their e-mail - [email protected] & [email protected]. In addition to that, victims must pay a ransom of $980 in bitcoins. It suggests that the victims reaching out to hackers within 72 hours of the encryption, will be given 50% in the ransom amount i.e., $480 (in bitcoins). Fake Claims by Hackers In order to guarantee the decryption, hackers ask victims to send them one file first via e-mail. The file should not contain any valuable information, the note says. The file will be decrypted for absolutely no cost & sent back to the victims. Fearing to lose their sensitive data, may victims contact the hackers & send them a file to decrypt. However, please note that these claims are false. The research has revealed that victims often stop receiving response from the hackers after receiving the ransom amount. Therefore, instead of panicking & contacting the hackers, the victims should act smart & do not let the hackers extort money from them.
