As an IT security pro, unless you've been hiding under a rock, you've heard about ransomware threats like Cryptolocker. These threats are typically delivered via an e-mail with a malicious attachment, or by directing a user to a malicious website. Once the Cryptolocker file executes and connects to the command and control server, it begins to encrypt files and demands payment to unlock them. As a result, detecting infection quickly is key to limiting the damage. AlienVault USM uses several built-in security controls working in unison to detect ransomware like Cryptolocker, usually as soon as it attempts to connect to the command and control server. Join us for a live demo showing how AlienVault USM detects these threats quickly, saving you valuable time in limiting the damage from the attack. You'll learn: How AlienVault USM detects communications with the command and control server How the behavior is correlated with other signs of trouble to alert you of the threat Immediate steps you need to take to stop the threat and limit the damage

- Most organizations look like this… there’s a myriad of security solutions in their environment all promising to deliver greater visibility.
- Step 3: Cryptolocker connects to random URL to download RSA Public Key Step 4: Crates AES-256 key for each file, uses AES-265 and RSA encryption method. Encrypts files using the AES-256 key, which is encrypted using the downloaded public key.
- If you don’t pay by the deadline, the files are lost
