Informing the Electronic Crime Prosecutor's Office about the emergence of a new malware, called CTB-Locker
The Electronic Crime Prosecutor's Office informs citizens of the emergence of a new malware, named as CTB-Locker (Curve-Tor-Bitcoin Locker) and is detected as "Critroni", and is the evolution of the known malware Crypto locker Ransomware.
In particular, the new malware, with its installation in the operating system, encrypts various file types (photos, videos, documents, etc.).
Then it displays one message "blocking" the computer, informing the user that, in order to unlock their files, a ransom must be paid.
The money is paid using the bitcoin (BTC) digital currency. If the victim does not have bitcoins, software developers provide instructions for acquiring them.
Like in Cryptolocker, malicious software "Critroni" creates a pair of public and private "keys", which are essentially code numbers, which "unlock" the infected computer.
One "key" (public) is stored on the infected system and given to the user freely, without payment. The other "key" (private) is stored on the administration and control server (C&C servers) and given by the perpetrators to the victim to decrypt the files, only after the payment of the requested and agreed amount, which is always in digital bitcoin currency.
The procedures and ways of spreading the above malicious software are similar to Cryptolocker's malware.
Internet users are urged to be particularly careful and take the following protection measures to prevent malicious software from being compromised.
Specifically:
-
to check and keep up-to-date the version of their operating system,
-
to make copies security of their device files (backup) at regular intervals, on an external storage medium,
-
to use security applications such as antivirus, which must always be up to date
-
not open the links and not download the attachments contained in emails for which they are not sure about the sender and the contents of the attached file.
