Anti-Cryptor allows you to protect your files in local directories with network access by SMB/NFS protocols from remote malicious encryption.
While the Anti-Cryptor component is running, Kaspersky Endpoint Security scans remote devices calls to access the files located in the shared network directories of the protected device. If the application considers a remote device actions on network file resources to be malicious encrypting, this device is added to a list of untrusted devices and loses access to the shared network directories. The application does not consider activity to be malicious encryption if it is detected in the directories excluded from the protection scope of the Anti-Cryptor component.
This feature is not supported in the KESL container.
To use the component, a license that includes the corresponding function is required.
For the Anti-Cryptor component to operate correctly, at least one of the services (Samba or NFS) must be installed in the operating system. For the NFS service, the rpcbind package must be installed.
Anti-Cryptor operates correctly with the SMB1, SMB2, SMB3, NFS3, TCP/UDP, and IP/IPv6 protocols. Working with NFS2 and NFS4 protocols is not supported. It is recommended to configure your server settings so that the NFS2 and NFS4 protocols cannot be used to mount resources.
Anti-Cryptor does not block access to network file resources until the device activity is identified as malicious. So, at least one file will be encrypted before the application detects malicious activity.
