A security expert has warned iPhone and Android users to be aware of a 'pig butchering' cryptocurrency scam which is rising in popularity.
The tactic sees a vague greeting such as "Hey" or '"How's it going, James?" sent via text or social media, intending for the recipient to reply saying they have the wrong number.
Once they get a response, the scammer will try to engage in conversation and build up a friendship to gain a sense of trust.
