However, it is not recommended to contact/ pay to the crooks under any circumstances. It is because these people often do not send the decryption tool even if all their demands are met. The only possible way to recover the files without the interference of the crooks behind it is to restore the files using backups.

How did .Lisp ransomware intrude in?

Ransomware and other malicious malware are often distributed through Trojans, mal-spam campaigns, unreliable software download sources/ channels, fake software updating and unofficial activation tools. Trojans are malicious programs that are designed to download/ install additional malware. Mal-spam campaigns are used to send spam emails that contain infectious files or links for such files. If downloaded or opened, such files initiate the malware download/ installation process. Examples of such files are malicious Microsoft Office or PDF documents, JavaScript files, archive files and executable files. Unreliable downloading sources like p2p networks, free file hosting sites and third party downloaders/ installers spread malware by presenting it as legit software. Fake software updaters infect computers either by installing malware instead of updates, fixes for installed software or by exploiting bugs, flaws of installed software that is not up-to-date. Unofficial activation tools infect systems simply by installing malware instead of bypassing activation keys for paid software.

How to prevent ransomware infection?

Attachments or website links should never be opened if they are presented on any emails whose senders’ addresses seem suspicious and irrelevant. Files and programs should be downloaded only from official websites and direct links. Other sources, tools like third party downloaders, unofficial websites, p2p networks, free file hosting sites and etc should never be used. Unofficial, fake software updating and activation should never be used as well. Software update and activation should be done using official software developers’ tools/functions only. Additionally, a computer should have a reputable antivirus tool and this tool should be up-to-date. If .Lisp ransomware already infiltrates in, run a full system scan using some reputable antivirus tool to automatically elimination this ransomware.
