What is InfinityLock ransomware? And how does it execute its attack?
InfinityLock ransomware is a file-encrypting threat discovered by Leo, a malware security researcher. The InfinityLock ransomware developers proliferates the malware by presenting it as a “crack” for Adobe Premiere Pro software. It uses a sophisticated encryption in encrypting its targeted files and changes the infected PC’s desktop wallpaper and delivers a ransom note named INFINITYLOCK_UNIQEID.txt that contains the following message:
“YOU BECAME A VICTIM OF THE INFINITYLOCK RANSOMWARE!
ALL YOUR FILES HAVE BEEN ENCRYPTED
FOR EACH TRY TO DO ANYTHING I WILL DELETE FILES
PAY 0.17 BITCOINS TO THIS ADDRESS : 1LSgvYFY7SDNje2Mhsm51FxhqPsbvXE
YOU CAN BUY BITCOINS ON “BLOCKCHAIN.INFO”
SEND YOUR UNIQE ID IN THE DESCRIPTION OF THE BITCOIN PAYMENT
YOU CAN FIND THEM ON YOUR DESKTOP IN “INFINITYLOCK_UNIQEID.TXT”
AFTER THE PAYMENT YOUR FILES WILL BE DECRYPTED!”
During the encryption process, InfinityLock appends a random file extension to each targeted files such as images, audio, video, archives, documents and other types of files using RSA 2048 encryption algorithm which will make it difficult to recover these files without a decryption tool. The malware also creates three files – InifinityLock_Recover_Instructions.png, InfinityLock_UniqeID.txt and InfinityLock_Recover_Instructions.txt. All these files are placed on the desktop and the png file is the one set as desktop wallpaper. Aside from that, the malware also uses three separate executable files to facilitate its operations namely: encrypt.exe, setinstructions.exe and sendhelp.exe.
InfinityLock also displays a fake Command Prompt window informing users about a ransomware attack. Here’s the full context of the message:
C:\Users\[account name]>encrypt.exe -alldata -randomkeysend -rsa-2048 -alldrives
C:\Users\[account name]>setinstructions.exe -silent -desktop
C:\Users\[account name]>sendhelp.exe -incmd -me
YOU BECAME A VICTIM OF THE INFINITYLOCK RANSOMWARE !
ALL YOUR FILES HAVE BEEN ENCRYPTED
PAY 0.17 BITCOINS TO THIS ADDRESS_
Victims are also urged to send Bitcoins to the given address and include their unique ID number in the description in order to recover their files. However, time and time again, security experts do not recommend paying these crooks any single cent for no assurance is given that they will decrypt the encrypted files once payment is made. The best thing you could do is to eliminate InfinityLock by following the instructions provided at the end of this article.
How is InfinityLock distributed?
InfinityLock ransomware spreads as a malicious executable file named PremiereCrack.exe. According to security analysts, the InfinityLock ransomware payload is presented to users as a cracked copy of the Adobe System’s Adobe Premiere Pro CC by Adobe Systems Inc. which is a video editing and production software solution. Pirated copies of this software are used to distribute threats in the past, and right now, InfinityLock is also utilizing this method. Users are can most likely encounter this threat right after downloading software cracks from peer-to-peer networks, unofficial download sources such as free sharing sites offering software bundles, fake software update tools, Trojans and the old but gold malicious spam email campaigns. These third party software download sources sometimes present malicious applications as legitimate ones, thus, tricking users into downloading and running the malware-laden software. If you want to stir clear of any potential and serious threats, it would be best if you avoid downloading software cracks and download the software from its official website instead.
