SINGAPORE - Deliveroo Singapore has said that some local accounts were compromised as of Friday (Nov 25).

"These accounts have been suspended and are being assessed. If anyone believes that their account has been compromised, they should reach out to Deliveroo as soon as possible for assistance," a spokesman said.

Users can do that by checking their order history, the spokesman added. Deliveroo declined to reveal how many accounts were affected, but said it was "very few".

It urged customers to "use strong and unique passwords for every service they use".

Earlier, it was reported that Singapore customers had not been affected by compromised accounts in Britain.

But less than a day later, Deliveroo became aware of "fraudulent activity affecting a small number of local accounts".

BBC Watchdog reported this week that customers in Britain were billed for food they did not order.

One user, Ms Judith MacFadyen, told BBC that she was charged £200 (S$354) for four orders of burgers delivered to a few addresses.

The customers affected had their money refunded, BBC said.

"We are aware of these cases raised by Watchdog - they involve stolen food, not credit card numbers," Deliveroo said in an earlier statement.

The London-based company said that no financial information was stolen, as passwords stolen from other online services were used to access Deliveroo customers' accounts.

"That said, we can assure customers that we are constantly improving our security measures, and make regular upgrades to our practices," it added.

"Recently, this included frequently asking customers to verify themselves when entering a new address."

The company also uses machine learning to track "patterns of criminal activity", it said.

It declined to elaborate on measures to counter fraud due to security concerns.

Deliveroo, which was founded in 2013, launched in Singapore in late 2015.

Another food delivery company here, UberEats, has said that it ensures the "safety of its platform and those who use it".
