Multiple BDO Users Allegedly Fall Victim to Online Banking Hack

So the bank transfers happened without the source account receiving OTP, bakit kaya? This may mean either na hack yung phone number nila for OTP or sa system mismo ng BDO na hack.

And the amount transfers are usually 50k, maybe because this is the amount limit for money laundering to trigger?

And it was transfered to union bank which they say can easily be converted to crypto.

I really want to know how this happened and how can this be prevented. Alarming Yung walang OTP.
