LambdaLocker Ransomware – Distribution

The LambdaLocker ransomware can be distributed by utilizing various methods. The most common way of distribution is probably by a file that drops the payload of the ransomware, which contains the malicious script of the virus.

LambdaLocker could also be distributing that payload dropper on social media networks and file-sharing sites. Freeware programs found on the Web could be promoted as helpful but also could be hiding the downloader for the payload. Do not open files right after you have downloaded them, especially if they come from a suspicious source, like an e-mail from an unknown sender. Instead, you should first scan those files with a security program and check their size and signatures for each of file for anything that seems unusual. You should read the tips for preventing ransomware topic.

LambdaLocker Ransomware – Information

LambdaLocker ransomware is also a cryptovirus. China seems to be the primary country that it is currently targeting, according to malware researchers. There is also the evidence that the ransom note has a variant written in the Chinese language. That doesn’t mean that other countries are excluded from its crosshairs – everybody can become a victim. The ransomware will encrypt files on your computer system and append the same extension to all of them when the encryption process finishes.

LambdaLocker ransomware could make new entries in the Windows Registry to achieve perseverance. Those registry entries are usually placed for the reason to start the virus automatically with each boot of the Windows Operating System.

The ransom note will appear after the encryption process is fully completed. The note states what the demands of the cybercriminals are, like what is the price of the ransom and all other instructions for decrypting your data. The note is contained in a file called READ_IT.hTmL. You can preview the ransom note in the screenshot provided down below:

The criminals that stand behind the LambdaLocker ransomware virus want 0.5 BitCoin for decryption, which is a bit more than 400 US dollars. You should NOT under any circumstances pay these criminals. Nobody can guarantee if your files will get restored back to normal. Plus, you should not ever give money to criminals, as this will probably just support them and inspire them to make other ransomware viruses or do more criminal activities.

At this time, there is no existing list with file extensions that the LambdaLocker ransomware searches to encrypt. The article will get updated if any information on that matter surfaces.

Each file that gets encrypted will receive the same extension appended to each of them, which is .lambda_l0cked. The encryption algorithm is a mixture of the 256-bit AES and 256-bit SHA algorithms or at least, that is what is says in the ransom note.

The LambdaLocker cryptovirus is very likely to delete the Shadow Volume Copies from the Windows operating system by using this command in the Command Prompt:

→vssadmin.exe delete shadows /all /Quiet
