SANTIAGO – A 23-year-old computer engineer has been arrested as the suspected perpetrator of a leak of bank data on some 80,000 clients of BancoEstado, Chilean police said on Thursday.
The alleged hacker, identified as Gonzalo Villegas Soto, works as an independent consultant and was arrested in Santiago by detectives from the police Cybercrime Brigade.
“Using his knowledge, he was able to detect a vulnerability in the information system,” the brigade’s deputy chief, Cristian Gonzalez, told reporters.
He said that detectives had found evidence among the suspect’s belongings linking him to the crime.
According to Gonzalez, nothing appeared to suggest that the leak led to any transactions, confirming what bank regulators and BancoEstado had said Wednesday.
The leak, which was one of three incidents that took place early Wednesday morning, was carried out with a Twitter account that uploaded a file with the names, tax identification numbers, and e-banking codes of 80,000 clients of BancoEstado.
Hours later, another file was uploaded with the e-banking codes of 170,000 clients.
Jorge Atton, a cybersecurity consultant for the Ministry of the Interior, called the arrest “good news” and said that the ministry would collaborate in the investigation.
The other two incidents that took place Wednesday include the leak of a list of employees of a financial institution and the apparent deletion of information of 500 people from a national registry of debtors.
