Back to Ransomware


One of Chile’s largest banks affected in a ransomware attack

On September 6, 2020, BancoEstado, one of Chile’s biggest banks, reported a ransomware attack on its premises. Following the attack, the bank closed down all of its branches on September 7 to investigate the attack. The virus strain that affected the bank’s network is believed to be REvil or Sodinokibi ransomware.

The virus infected the systems when an employee accidentally opened a malicious Word file that was believed to be planted by hackers via a backdoor. The attack was detected when employees were unable to access the files on September 5, 2020. The internal servers and devices remained inaccessible to staff. Due to the network segmentation techniques in place, the bank's website, banking portal, mobile apps, and ATMs were unaffected.

The news was reported to the authorities the same day it was detected. So far the investigations have revealed that the customers’ funds were not affected. The government’s cybersecurity unit CSIRT also took steps to warn private sector organizations about the targeted ransomware campaigns.
