The customers of Banco Pichincha, the largest bank in Ecuador, are still experiencing service disruptions after a massive cyberattack hit the financial organization early this week.
The cyberattack took place over the last weekend and forced the bank to shut down a large part of its computer network in response to the incident.
Many services of the bank were disrupted, including online banking, mobile app, and ATM network, many customers crowded the Pichincha bank branches that remained open the days after the cyber attack. The Banco Pichincha has about 1.5 million clients for a portfolio of $1.5 billion.
The bank issued a statement on Monday to inform the customers about the cyber attack, it also added to have “identified a cybersecurity incident in our systems that has partially disabled our services.”
The main bank shareholder, Fidel Egas, tweeted that “We are doing the impossible. They want to blame us for something in which we are the victims.”
The authorities, including the Superintendency of Banks, are investigating the incident.
The public information about the attack suggests that the bank was the victim of a ransomware attack, sources in the cybersecurity industry confirmed it to BleepingComputer.
This is the second attack suffered by the Ecuador bank this year, in February a cybercrime group called ‘Hotarus Corp’ has breached the Banco Pichincha, and the local Ministry of Finance (the Ministerio de Economía y Finanzas de Ecuador).
