LambdaLocker Ransomware Description

The LambdaLocker Ransomware is a newly discovered malware threat which is still under investigation by the security community. At this time it is not known if it it originates from a known malware family or it is an independent creation.

All affected files receive the .lambda_l0cked extension.

Once the encryption process is complete a ransom note is displayed to the user in both English and Chinese. The English note contains the following message:

Your files are encrypted by the LambdaLocker.
