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.
On 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:
[email protected]
Your ID for Decryption: r4o7x*****
If You Try 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, cyber criminals 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.
To effectively kill ZeroAdypt ransomware from your infected computer, make sure to follow the removal instructions below.

Step 8: Next, tap Ctrl + Shift + Esc to open the Task Manager and then go to the Processes tab and look for the malicious processes of ZeroAdypt Ransomware and end them all.
Step 9: Open Control Panel by pressing Start key + R to launch Run and type appwiz.cpl in the search box and click OK to open the list of installed programs. From there, look for ZeroAdypt ransomware or any malicious program and then Uninstall it.

Step 10: Tap Windows + E keys to open the File explorer then navigate to the following directories and delete the malicious files created by ZeroAdypt ransomware such as READ-Me-Now.txt and [random].exe.

• %UserProfile%\AppData

• %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup
• %TEMP%.
• %USERPROFILE%\Downloads
• %USERPROFILE%\Desktop

Step 11: Close the File Explorer.

Keep in mind that any changes you make will highly impact your computer. To save you the trouble and time, you can just use [product-name], this system tool is proven to be safe and excellent enough that hackers won’t be able to hack into it. But if you can manage Windows Registry well, then by all means go on to the next steps.
Step 12: Tap Win + R to open Run and then type in regedit in the field and tap enter to pull up Windows Registry.

Step 13: Navigate to the paths listed below and delete all the registry values added by ZeroAdypt ransomware.

• HKEY_CURRENT_USER\Control Panel\Desktop\
• HKEY_USERS\.DEFAULT\Control Panel\Desktop\
• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Step 14: Close the Registry Editor and empty your Recycle Bin.
After you’re done with the steps given above, you need to continue the ZeroAdypt ransomware removal process using a reliable program like [product-name]. How? Follow the advanced removal steps below.
Perform a full system scan using [product-code]. To do so, follow these steps:
