Fraud

From late November to early December 2021, [1] numerous accountholders of BDO Unibank (Banco de Oro; BDO) lost their money through unauthorized bank transfers. The funds were noted to have been transferred to multiple Unionbank accounts under the name of a certain "Mark Nagoyo". [2] [3] Fraud victims lost money ranging from ₱25,000 to ₱50,000 per BDO account. [1]

The scheme has been characterized to have made through hacking. [4] Several Facebook groups were made by the fraud victims, where many maintained that they did not click any dubious links, sent through messaging apps, SMS, or email, that would make them fall for a phishing attempt. Other accounts suggest that they did not receive any one-time password (OTP), that would have alerted them to someone making an unauthorized login to their bank accounts, receive any OTP that a new device was linked to their accounts, and some had funds larger than the daily limit transferred out of their accounts. Manila Bulletin Technews also reported that funds worth ₱5 million transferred to one Unionbank account were used to buy Bitcoin on December 11. [1]

There are also accounts of victims saying that perpetrators used other platforms such as GCash and the Bank of the Philippine Islands (BPI) instead of Unionbank. [5]

Perpetrators

The name "Mark Nagoyo", [lower-alpha 1] which is associated to the Unionbank accounts, is believed to be fictitious or a pseudonym. By December 15, the Bangko Sentral ng Pilipinas, the Philippines' central bank, has identified two to four people as perpetrators of the hack. These people were neither employees of BDO or Unionbank. [7] Five suspects, two Nigerian nationals and three Filipinos have been arrested in relation to the hack. [8]

Response

BDO released a statement on December 12, 2021, that some of its accountholders were affected by "a sophisticated fraud technique" and has pledged to reimburse the lost funds to the fraud victims and bolster its security infrastructure. The Bangko Sentral ng Pilipinas, has said that it is monitoring the increase of complaints on the incident on various social media platforms and is working closely with BDO and Unionbank over the incident. [9] [3] Fewer than ten Unionbank accounts which received funds from BDO accounts have been frozen in response to the incident. [10] The National Privacy Commission also coordinated with BDO to determined if any personal information was compromised in connection to the incident. [11] Globe Telecom has also pledged assistance to the central bank on its investigation. [12]

On December 14, BDO announced that it is reimbursing funds of around 700 account holders. [13] It was reported that BDO is requiring victims to sign a quitclaim before reimbursing their lost money, in exchange of not filing legal charges against the bank. According to DTI undersecretary Vic Dimagiba, this could put victims at a disadvantage since they could potentially be entitled to more claims than the funds lost to the hack; such as losses arising from the inability to process the affected account holders' housing loan installment payment. [5]

The BSP on December 17, disclosed that its initial findings suggests that the stolen funds from BDO may have also been transferred to multiple banks and non-bank financial institutions financial institutions aside Unionbank. [14]

On January 21, 2022, the National Bureau of Investigation presented five suspects who were arrested in relation to the hack. [8]

Reactions

Bayan Muna has called for the Committee on Banks and Financial Intermediaries of the House of Representatives to launch a legislative inquiry over the incident. [15]

The Bankers Association of the Philippines issued a statement reminding bank accountholders to never give their personal information, including OTPs to other people and urged the public to remain vigilant against cybercrimes. [16]

"Operation Big Bird" was the attempt of the Philippine Government during the presidency of Corazon Aquino to recover the alleged US$7.5 billion of hidden accounts and assets of President Ferdinand Marcos and his family in the Swiss banks. Conceived by Philippine banker Michael de Guzman, it commenced shortly after Marcos was forced into asylum in the United States. Initially, Operation Big Bird did not recover any money with two differing reports by Representative Victorio Chaves and Senator Jovito Salonga. Chaves laid the blame upon Salonga, Solicitor-General Sedfrey Ordoñez and the Swiss bank lawyers. Salonga countered that Ordoñez had prevented the Philippine government from losing a large sum of money. Evidence suggests that de Guzman acted in good faith on behalf of the new government but that a double cross may have been present.

The Bangladesh Bank robbery, also known colloquially as the Bangladesh Bank cyber heist, was a theft that took place in February 2016. Thirty-five fraudulent instructions were issued by security hackers via the SWIFT network to illegally transfer close to US$1 billion from the Federal Reserve Bank of New York account belonging to Bangladesh Bank, the central bank of Bangladesh. Five of the thirty-five fraudulent instructions were successful in transferring US$101 million, with US$81 million traced to the Philippines and US$20 million to Sri Lanka. The Federal Reserve Bank of New York blocked the remaining thirty transactions, amounting to US$850 million, due to suspicions raised by a misspelled instruction. As of 2018, only around US$18 million of the US$81 million transferred to the Philippines has been recovered, and all the money transferred to Sri Lanka has since been recovered. Most of the money transferred to the Philippines went to four personal accounts, held by single individuals, and not to companies or corporations.

In 2015 and 2016, a series of cyberattacks using the SWIFT banking network were reported, resulting in the successful theft of millions of dollars. The attacks were perpetrated by a hacker group known as APT 38 whose tactics, techniques and procedure overlap with the infamous Lazarus Group who are believed to be behind the Sony attacks. Experts agree that APT 38 was formed following the March 2013 sanctions and the first known operations connected to this group occurred in February 2014. If the attribution to North Korea is accurate, it would be the first known incident of a state actor using cyberattacks to steal funds.
