Lalo virus is hazardous computer threat and considered as ransomware. Typically, ransomware-type programs attack computers to encrypt files and force victims to pay a ransom fee or purchase a decryption tool. Lalo ransomware adds .lalo file extension to all the infected files. For example, the existing file summary.docx will become summary.docx.lalo once encrypted. As part of the operations, Lalo will drop a ransom note to the victim’s computer within a text file named _readme.txt.

The ransom note contains the message of the hackers stating that Lalo ransomware encrypts files that may include personal documents, photos, databases, or any valuable data of the victims. Lalo uses a strong encryption algorithm in order to encrypt target files. All infected files will be inaccessible and remain locked until the victims pay the ransom fee. The cost of ransom demand normally cost $980. However, the ransom fee may also vary depending on how quickly the victims will contact the Lalo ransomware creators. There are instances that the Lalo ransomware developers offer a 50% discount to the victims who will send an email to specified email address within 72 hours. The victims are requested to attach a personal identification together with one infected file, which Lalo developer will decrypt free of charge. After that, Lalo developers will send instructions on how to make payments that are usually through crypto-currency or Bitcoin.

Unfortunately, only Lalo developers can provide the appropriate decryption tool for the files encrypted by their ransomware. Hence, there are cases that hackers will never send the decryption tool even if victims have paid the ransom fee. The main point is, do not ever trust cyber-criminals, and always secure the important files or data with a backup. In that way, it is easier to recover the files in case ransomware attacks.

Clicking and opening such files could possibly execute the ransomware on the computer. Therefore, beware of opening unfamiliar email messages especially if the sender’s address is somewhat suspicious. It might inject malware or any infectious content to the computer.
