What is ImSorry ransomware? And how does it implement its attack?
ImSorry ransomware which also goes by the name “Sorry” ransomware is a new file-encrypting virus that recently wreaked havoc online. This dangerous crypto-malware aims to lock important files in an infected system. ImSorry ransomware implements attack using a malicious executable file named “ImSorry.exe” – this malicious file gets dropped into the system when you click or open a corrupted file from spam emails.
Once the malicious file is executed, it makes a series of adjustments into the system. These adjustments involve the modification of registry entries so that the ransomware can run on every system boot. It also creates and modifies other system files to make sure that nothing will stop it from implementing its attack into the infected system. After that, ImSorry ransomware will begin to scan the computer looking for files to encrypt. It may encrypt files with the following file extensions:

During the encryption, ImSorry ransomware will use both the AES and RSA encryption algorithms in locking the targeted files. Right after the encryption, it appends the .imsorry extension to each one of the files and delivers its ransom note that contains the following context:
