What To Do If You Receive a DDoS Ransom Note

One of the most common motivations for a DDoS attack is extortion, where an attacker threatens to take down a site unless the victim pays, typically in the form of a Bitcoin transaction.

Unfortunately, these types of extortion attempts are increasing in both intensity and volume. In recent years, a hacking group called ‘Lizard Squad’ has been responsible for sending demands to a number of high-profile companies, including Sony and Instagram.

Method of attack

The attacker will typically send emails demanding payment of bitcoins. In the ransom note, it will state that if the demand is not met, the hackers will launch a Denial of Service (DoS) attack against the businesses’ websites and networks, taking them offline until payment is made. The demand will state that once their actions have started, they can’t be undone.

What to do if you receive a DDoS ransom note

1. Do not under any circumstances pay the demand
2. Report it immediately to Action Fraud by calling 0300 123 2040 or by using their online reporting tool
3. Retain the original email(s) (with headers)
4. Maintain a timeline of the attack, recording all times, type of contact and the content
5. Contact Daisy to see if we are able to protect you within 24 hours*
