It's been targeting iPhone and Android devices for a number of years but people are still being tricked by the dreaded "Hi mum" message scam. This horrifying attack first began via WhatsApp messages back in 2021 but in recent months it has spread to standard SMS texts as well making it an even bigger problem.
Those caught out by the swindle can find themselves thousands of pounds out of pocket with one phone owner recently telling the BBC that she had lost over £3,000 after handing cash to fraudsters.
Jan - which is not her real name - said she received a message saying , "Hey mum I am texting you on my friends phone as my phone is broken".
