Social media posts circulated this week purportedly showed how some depositors lost money due to "skimming" or copying of account details through hijacked ATM machines.
"BDO has obtained reports of potentially compromised ATM following reported losses from cardholders," the bank said in a statement.
"Customers with unauthorized transactions may reach out to the bank via formal channels so that their cases may be properly investigated and, where confirmed as impacted, may be reimbursed," it said.
The bank owned by the country's richest man, Henry Sy, said "all efforts" were being made to keep accounts safe.
The ATM fraud reports came a week after Bank of the Philippine Islands' electronic services were paralyzed for 2 days due to what it said was an "internal" glitch.
