BOSS, the British Oil Security Syndicate, is warning forecourt retailers to beware of extortionists after Action Fraud received reports from businesses who have been sent online extortion demands from scammers threatening a cyber-attack.

The scammers who call themselves the “RepKiller Team” have been sending emails to businesses across the UK demanding payment of between £300-£500 in Bitcoins by a certain date and time.

If the demands are not met, the team have threatened to launch a cyber-attack against the businesses and their reputation by automating hundreds of negative reviews online.

The emails also claim that once actions have started, they cannot be undone. Although these scammers are currently calling themselves “RepKiller”, it is common for fraudsters to continually change and adopt new tactics – email names can be made and changed easily.

Boss has released the following advice for retailers who receive such demands:

• Whether the attack is attempted or successful, you should report it to Action Fraud on 0300 123 2040 or by using the Action Fraud online reporting tool and receive a police crime reference number.

• Do not pay the demand. There is no guarantee the scammers won’t launch an attack and could encourage further extortion demands in the future.

• Retain all the original emails. Should law enforcement investigate, the information contained within the email headers can be used as evidence.

• Maintain a timeline of the attack recording all times, type and content of contact.

• You can now also sign up for free to Action Fraud Alert to receive direct, verified, accurate information about scams and fraud in your area by email, recorded voice and text message.
