New alert issued as Action Fraud reveals staggering rise of extortion phishing email reports.

Action Fraud are urging the public to look out for phishing emails that relate to extortion as the Suspicious Email Reporting Service (SERS) received over 2,924 reports in March 2025, a staggering increase compared to only 133 reports made in February.

The reported phishing emails received by the National Cyber Security Centre’s SERS relate to a type of extortion referred to as ‘Financially Motivated Sexual Extortion’ (FMSE).

Detective Chief Inspector Hayley King, Head of Prevention in the National Fraud Intelligence Bureau (NFIB) said:

“Criminals will go to great lengths to make these types of extortion scams more convincing, including using a leaked password or home address in the phishing email to make it seem genuine.

“Follow our advice if you think you’ve received one of these phishing emails: forward it to report@phishing.gov.uk and delete the email after that. If you spot genuine personal information in an email, it is likely it came from an historic data breach – you can check if you’ve been affected by one in the past.

“Please contact your local police force if you have been a victim of extortion. Even if you have concerns someone may possess of intimate images of you, you should tell the police by calling 101.”

Reports suggests the phrasing of the email and subject lines can vary, but the theme remains consistent: the phishing email claims to have installed malware on the recipient’s computer and recorded them visiting adult websites. The sender will then coerce the email recipient to pay a ransom demand by threatening to release the videos. The ransom is usually demanded in a form of cryptocurrency, such as Bitcoin.

In order to make these phishing attacks convincing, emails will often include genuine pieces of personal information relating to the victim, such as a password or home address. It is likely these would have been obtained from historic breaches of personal data.

Analysis shows that many people who received these emails also later reported becoming victims of online account hacking.

In 2024, a male victim in his thirties received numerous extortion emails that contained a password he used for one of his online accounts. The emails demanded a ransom of $500. Having correctly identified the emails as a scam, he deleted them. However, shortly afterwards he noticed that he was unable to login to one of his social media accounts. After some checking, he realised that one of his bank accounts and multiple social media accounts had been hacked and he was locked out of them.

What to do if you receive an email like this:

• As with other phishing emails, do not to engage with the phisher, forward the email to report@phishing.gov.uk, which is the NCSC’s Suspicious Email Reporting Service (SERS), and then delete it.
• If you are considering paying the Bitcoin ransom, you should be aware that doing so, you will likely become the target of more scams, as the phisher will know they have a ‘willing’ customer.
• The inclusion of genuine passwords or other personal information in phishing emails is a strong indication that you may have been affected by a historic data breach. You can use this service to check which of your online accounts were affected:  https://haveibeenpwned.com
