Attackers stole $130 million from Brazil’s real-time payment system on Friday by wielding valid credentials for an IT service provider.

The unauthorized transfer of funds, some of which have been recovered, involved unauthorized access to an IT environment operated by financial technology provider Sinqia, a Brazilian subsidiary of publicly traded Evertec. Based in Sao Paulo, Brazil, Sinqia provides a platform used by 24 banks to connect to the Brazilian Central Bank’s real-time payment system, called Pix.
Preliminary results from an ongoing digital forensic investigation into the attack “indicate that the unauthorized transactions were introduced into Sinqia’s Pix environment by exploiting legitimate Sinqia IT vendors’ credentials,” Evertec disclosed to investors.
Evertec, a major financial technology and transaction processing service supplier to Latin America and the Caribbean and based in San Juan, Puerto Rico, acquired Sinqia in November 2023.
Sinqia said that it “halted transaction processing in its Pix environment and began working with outside cybersecurity forensics experts” after detecting hacking activity.
The Central Bank of Brazil launched Pix in 2020. The service allows users to transfer funds using their mobile phone. It has counts of 169 million registered members and in July handled $6.4 billion in transactions. The service has been used by 94% of adults in Brazil, which has a population of 211 million, of which two-thirds say it’s their most frequent method of payment, slightly ahead of debit cards and cash, according to a recent survey conducted by Google.
The Brazilian Central Bank was able to immediately disconnect the company’s IT platform from Pix to block any further unauthorized transfers, as well as freeze at least some of the stolen funds, reported local media. So far $64 million has been frozen, with the central bank saying it hopes to recover even more of the funds.
Brazilian law enforcement is investigating the attack.
Sinqia said that of the two dozen Brazilian financial services firms that use its platform to connect to Pix, attackers successfully executed “business-to-business financial transactions” to steal funds from two. Local media identified the victims as banking giant HSBC, which lost $70 million, and fintech firm Artta, which lost $7 million.
Sinqia’s connection to Pix remains offline, pending a full review by the central bank.
The company said that it believes the incident solely affected its systems that connect to the Pix environment and said it’s seen no signs of further compromise, or exposure of personal data.
In a statement, HSBC said it attempted to block the unauthorized transactions in the Sinqia environment after they occurred, and pledged to work with law enforcement to investigate the attacks.
Fintech Artta said in a statement it’s liaising with Sinqia and the BCB, and hopes to resume service as quickly as possible.
Evertec warned investors that “the financial and reputational impact of the incident, including any impact on the company’s internal controls, are not yet known and could be material,” and also that it has yet to determine “the scope of any liability associated with this matter, the applicability of any insurance coverage or what claims” that it may have against any culpable vendors or suppliers.
