"My credit card has just been hacked! May nag order ng P1M worth of food sa Food Panda in less than an hour," Gatchalian said in a tweet.

(Someone ordered P1 million worth of food from Food Panda in less than an hour.)

"Ano 'yan lauriat para sa buong barangay?" he said.

(Is that a lauriat for the entire village?)

The purchases were done in 4 transactions on January 5, between 4:47 p.m. and 5:49 p.m., according to transaction details the senator posted.

"The hacker managed to change my registered phone number so he got the OTPs," Gatchalian said referring to the One-Time Password, an added security code sent to a credit card holder via text.

"He knew what he was doing. I just don't know how he will eat a million worth of food," he said.

Gatchalian has yet to disclose developments on the fraudulent transactions.

The lawmaker from Valenzuela was ranked as the 9th richest senator last year with a net worth of P95 million.

Unionbank said in a statement it's investigating the hacking of Gatchalian's credit card and coordinating with Food Panda, which also started a probe on the issue.
