What is CyberDrill ransomware? And how does it execute its attack on the infected PC?

CyberDrill ransomware is an encryption Trojan which is based on the open source platform, HiddenTear. According to security experts, CyberDrill has been active since February 2017 but it wasn’t finished yet by that time and only in September 2017 was it able to finish its improved version. Like all other crypto-malware, CyberDrill aims to encrypt files in a computer and hold them hostage until a ransom is given.
Based on the reports, CyberDrill ransomware seems to target small and medium businesses specifically. Once it infiltrates your computer, CyberDrill connects to ransomuhahawhere.cyberdrillexercise.com website and address to download malicious files in the computer. It then connects to its remote server to start its attack. During its attack, it scans the computer’s drives for the following file types to encrypt:
.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.
It encrypts all the file types given above using the AES encryption algorithm and then appends the .locked file extension on each one of them. After it finishes the encryption process, CyberDril drops a ransom note in the form of a text file named READ_IT.txt and opens a program window labeled as Cyberdrill_2 Ransomware. Both the program window and the text file contain the ransom note such as follows:
“Ooops, your files have been encrypted
Files have been encrypted with Cyberdrill_2 Ransomware and many Users will not be able to access sites host…
This is not a joke, Check sites now.
Sites will be DDoS-ed starting in 48 hours if you don’t pay only5 Bitcoins @ [RANDOM CHARACTERS]
If you don’t pay in next 24 hours, attack will start, yor service going down permanently.
price to stop increase to 1 BTC and will go up 1 BTC for every day of attack.
POur attacks are extremely powerful. o cheap protection will help.
Bitcoin is anonymous, nobody will ever know you cooperated”
Its ransom amount is approximately almost $20,000 which is insanely huge. Instead of paying the ransom, you can try out alternative ways to recover the encrypted files. And besides $20,000 is a lot, not to mention that you don’t get any assurances that you’ll really get your files back if you pay this obscene amount.

How does CyberDrill ransomware spread its infection?

CyberDrill ransomware spreads as an obfuscated file executable file named Ransomuhahawhere.exe file and because of its malicious executable file’s name, CyberDrill ransomware is also referred to as Ransommuhahawhere ransomware. Once its payload is executed, the ransomware then creates a folder named CyberDrill where it downloads the ransom note.
