throwaway_qwe··on Making it clear when we're on a call with you to protect you from fraud
One of those on the 159 programme https://stopscamsuk.org.uk/159

Honestly, I’m not sure it matters. They’ve all had such incidents. I read somewhere that about 30% of your fees and mortgage interest go toward fraud mitigation,monitoring, and restitution.

I always live by these rules

- call them back, don’t talk to them

- ask why you need to do anything. It’s exceedingly rare a bank would call you to do something legit there and then. “I will do it later” will help. In fact that’s how I caught the phisher as I noted the aggravation in 1% of his voice.

- use credit cards, not debit cards, for purchases. They have far more protection.

- use all the 2FA and password complexity you can

- never use real info for challenge questions. Never use maiden name of mother etc. you can put “14 green fish” as the answer to the question if you like.

- make sure they are FSCS regulated, and try not to exceed that limit.

- understand FSCS does not cover you most phishing attempts, since the bank will claim they tried to warn you and were not negligent

- use private tabs for bank interactions

Through this experience I have learned not to trust “what we know about you” information they share. Do not underestimate HUMINT. A bank snitch could give up something as seemingly innocent (to them) as your “join date” and it be a lynchpin piece of info for a scammer.

This may all seem obvious to an HM reader. But it’s worth refreshing and reiterating.

No paper bank statement. No email bank statement. Only qif/csv export. iPhone app only (not web). Fairly sure it was either an inside job and/or openbanking API implementation.

It’s not coincidental. I had a story to tell and didn’t want to use my main account. Monzo is OK and I have a 2nd business account with them. I find it expensive personally, at £5pm, since other banks offer free service and per transaction costs that total less for me. After the phishing attempt I moved to NatWest, of all places.

This is possible. I had the account linked to a very well known and popular service that is owned by another bank. I don’t want to use names. But “bank transaction ids” were known I do not know if this is part of the spec. My theory was some export from bank 1 for openbanking was breached or in bank 2’s import was breached. But the news items are about bank 1. Also, they knew details like the date of account opening which was different to date of first transaction. I was not using openbanking in many places but I have now turned it off everywhere.

I was recently a target of a UK online bank phishing scam (not Monzo). They were highly sophisticated. They knew details of recent transactions, including bank transaction numbers that don’t show in any qif export or anything. They had a plausible reason to call (based on said visibility). They had researched my name and everything about me and my family that is online. They faked caller ID. Their ‘patter’ was so advanced that I do not know this extra layer of protection would have helped much. Luckily I didn’t finish the steps and lost no money.

It is clear the bank has had a severe exfiltration event. There are other reports that online. IMHO the law should make banks report breaches to the ICO and a record of the nature and size of the breach be public.

Through the process I learned that in the UK you can call 159 to directly contact your bank fraud dept (most banks) https://stopscamsuk.org.uk/159

I also learnt about the police’s Action Fraud hotline to report cybercrime. https://www.actionfraud.police.uk/what-is-action-fraud

The phisher was very determined. They called back in 15 minutes claiming to be from the bank fraud dept returning my call. Then 2 weeks later they called back claiming to be from Action Fraud.

However prepared you think you are for such an attack, my advice is to have utmost caution for every single call from anyone claiming to be anyone.

I also have a Monzo account. Even if they called me I wouldn’t use this. Hang up. Call them. Don’t let them call you.
