Scammers pretending to be Nando's have swindled money from around 2,500 First Direct customers.
Worried account holders have spotted dubious transactions from the popular restaurant chain despite never ordering from there.
Approximately 2,500 customers have been affected and some First Direct customers have been slapped with £70 payments appearing in their accounts, sometimes spanning several days, purporting to be from the chicken restaurant.
Concerned account holders have taken to online forums and Martin Lewis' MoneySavingExpert website to see if anyone else has been targeted.
One customer said: “My wife has never used Nando’s but had a payment over £60 on her card.

"She has changed card and pin numbers.”
Another claimed that they had been warned by First Direct about a possible fraudulent transaction by nandos.co.uk, but that the bank had missed transactions on three consecutive days which amounted to £70.
It's feared this scam could cost First Direct thousands when taking into account refunds, compensation and time spent dealing with customers.
A spokesperson from First Direct said: "We are aware of some low-value unauthorised retail transactions appearing on a small number of our customers’ cards.
“We want to reassure impacted customers that they will not be left out of pocket and apologise for any inconvenience caused.
“We take our customers’ security very seriously and will be reaching out to affected customers in the coming days.
“We would advise customers to regularly check their statements and get in touch if they notice any suspicious activity.”
Back in 2020, Nando's customers claimed they had been left hundreds of pounds out of pocket after falling foul to a cyber-attack.
The cyber criminals were thought to have used a technique called 'credential stuffing', which is where login data is stolen online and then used to hack into the person's other accounts.
