What is ZeroAdypt ransomware? And how does it implement its attack?
ZeroAdypt ransomware is a data encrypting malware first discovered in April 2019. Alternatively, it is also known as “.[[email protected]] ransomware”. According to researchers, it is a new variant of 0kilobyt ransomware. Unlike typical ransomware threats, this one does not encrypt its targeted files but overwrites them instead, with zeroes, which is why it’s named ZeroAdypt.
At the onset of its attack, ZeroAdypt ransomware creates and downloads additional files from its remote server. It then searches for certain files to encode. According to researchers, it targets dozens of file types – some of which are:
.3g2, .3gp, .7z, .accdb, .aes, .ARC, .asc, .asf, .asm, .asx, .avi, .backup, .bak, .bat, .brd, .bundle, .c, .cgm, .cmd, .cpp, .crt, .cs, .csproj, .csr, .csv, .db, .dbf, .dch, .der, .dip, .djvu, .doc, .docb, .docm, .docx, .dot, .dotx, .dwg, .edb, .eml, .flv, .frm, .gif, .gpg, .gz, .htm,.html, .hwp, .Iay6, .ibd, .iso, .jar, .jpeg, .jpg, .js, .jse, .key, .lay, .lbd, .log, .m2ts, .max, .mdf, .mdp, .mid, .midi, .mkv, .mml, .mov, .mp3, .mp4, .mpeg, .mpg, .msg, .myd, .myi, .nef, .ocx, .odg, .odp, .odp, .ods, .odt, .onetoc2, .ost, .otg, .otp, .ott, .PAQ, .pas, .pdf, .pern, .pfx, .php, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .pst, .pub, .py, .pyc, .pyd, .pyo, .rar, .raw, .rm, .rpa, .sb2, .sch, .sh, .sin, .sldm, .sldx, .slk, .snt, .sql, .sql, .sqlite3, .sqlitedb, .stc, .std, .sti, .stw, .suo, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .tar, .tar, .tbk, .tiff, .txt, .uop, .uot, .vb, .vbe, .vbproj, .vbs, .vcd, .vdi, .vdmk, .vmx, .vob, .vsd, .vsdx, .wks, .wma, .wncry, .wrav, .xdata, .xlc, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .zip
After it alters its targeted files, ZeroAdypt ransomware will open a text file named “READ-Me-Now.txt” which contains the following content:
“Your All Files Encrypted
For Decrypt Your Data Contact Me:
Your ID for Decryption: r4o7x*****
If You Try to Decrypt your file and damage it is Gonna Cost You more Price to Decrypt
you can Send 1MB Data For Decryption Test”
There’s no use paying the ransom demanded by ZeroAdypt ransomware when there’s no guarantee that the crooks will indeed give the decryption key so it’s best to wait until a free decryptor is released by security experts who, at the time of writing, are still trying to come up with a decryptor. In the meantime, you can just use backup copies of the affected files and prioritize the removal of the ransomware.
How is the malicious payload of ZeroAdypt ransomware spread over the web?
At the time of writing, it isn’t unclear how its creators spread this threat but in most cases, cybercriminals aim to infect as many users as possible in order to increase ransomware payments. To achieve that, not only do they use social engineering tactics but also exploit kits to proliferate. One of the most common exploit kits used by cyber crooks is the Rig exploit kit which helps in identifying system vulnerabilities and takes advantage of them to install the ransomware.
