As soon as this cryptomalware finishes its work, it presents email address to the victim. 

The ransom message which is displayed by JapanLocker claims: “LOCKED. The site has been locked!” It seems that there has been a new wave of “Locker” virus series. The “predecessor” of this family – CryptoLocker has been officially terminated a few months ago. However, there have been several other Locker threats appearing, such as CTB Locker, TorrentLocker, and VenusLocker.

After that, the virus opens a .txt message with the instructions of data recovery and payment transmission. Depending on the sense of personal greed, hackers may demand 1 (1BTC≈ 600 USD) or more Bitcoins. Looking back at the notorious case of CryptoLocker, the cyber criminals have managed to collect several millions of dollars revenue. Therefore, there are no or few reports about data return.

This virus has been named after the name of notorious layer Takahiro Karasawa. Dissatisfied Japanese citizens have made numerous mocking posts about his behavior. The scandals inspired hackers‘ imagination as well. However, the ransomware is surely not a small computer pest, as it uses several channels for distribution: spam messages and exploit kits.
