Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Restoro to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is InsaneCrypt Ransomware? And how does it execute its attack?
InsaneCrypt ransomware is a file-encoding Trojan which is based on the open source ransomware called desuCrypt. Three authors have copied and modified the open source code which was hosted on the public code repository Github.com. The desuCrypt ransomware was developed by a programmer with the handle “zerod4y” and can be found on Github.com/zerod4y/desuCrypt. According to researchers, there are two strains that are based on desuCrypt which were observed on January 23, 2018. The first strain was named “Insane@airmail.cc ransomware” which was released on January 18, 2018, while the second one was named “DeusCrypt ransomwarE” released on a few days later after the first strain came out.
These ransomware variants have many similarities which isn’t surprising since they were developed using the same open source code. Whereas most of their differences involves the encryption algorithm used in encrypting files. According to security experts, these variant, InsaneCrypt ransomware included, encrypts files with the following extensions:
.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2
After it finds the file extensions it’s looking for, InsaneCrypt ransomware encrypts them using a combination of AES and RSA ciphers to make files inaccessible to its victims. It then appends the “[firstname.lastname@example.org].insane” extension on each one of the files once it’s done with the encryption. It also drops a text file named “How_decrypt_files.txt” which contains the following ransom note stating:
“All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the email [email address]. You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After Payment we will send the decryption tool that will decrypt your files.
[unique ID string]”
If you are one of the unfortunate victims of InsaneCrypt ransomware, there is no need for you to be threatened as there is a way to decrypt the affected files.
How does InsaneCrypt ransomware spread its malicious payload(s)?
InsaneCrypt ransomware spreads its malicious payload through malicious spam emails. These spam emails contain a corrupted document with macro scripts that is used to initiate the attack on the targeted computer. That is why you have to be careful when opening attachments from your emails even if it looks like it was sent by some well-known company or individual since cybercriminals rely on social engineering tactics to trick users like you into opening an infected attachment.
