What is Lpcap ransomware? And how does it implement its attack?
Lpcap ransomware is a dangerous crypto-malware and is the latest addition to the Paradise ransomware group. Like other Paradise variants, Lpcap ransomware is created to encode important data in a computer. It attaches a “.lpcap” suffix to each file it encrypts.
Once it starts to execute its attack, it drops its payload file in the system and initiates a sequence of malicious activities with the purpose of plaguing essential system settings and processes. It downloads other malicious components and places them to system folders. It then modifies the registry keys and sub-keys like Run and RunOnce in the Windows Registry to allow the automatic execution of the attack every time a user turns on the infected computer which makes its attack persistent. It also employs data gathering and stealth protection modules in order to collect sensitive information in the system and to evade security and antivirus programs. After all the modifications are completed, Lpcap ransomware will begin the encryption process using the RSA 2048 encryption algorithm. After it encrypts data, it appends the “.lpcap” extension to each one of the encrypted file and opens an html file named “RETURN FILES.html” that has the following ransom note:
“All your files was encrypted!
Ur personal ID
[Redacted] Your personal KEY
YOUR FILES HAS BEEN LOCKED!

How does Lpcap ransomware proliferate?
It isn’t clear yet how this new Paradise variant proliferates but it could be using malicious spam email campaigns. Its developers attach an obfuscated attachment to emails that once opened, will run a malicious script on computers which will launch Paradise ransomware. This is why you need to be more careful in opening and downloading attachments from suspicious-looking emails as they might contain the malicious payload of Lpcap ransomware.
