Details about the attack have not been made public, but a source close to the investigation told ZDNet that the bank’s internal network was infected with the REvil (Sodinokibi) ransomware: The incident is currently being investigated as having originated from a malicious Office document received and opened by an employee. The malicious Office file is believed to have installed a backdoor on the bank’s network.

Investigators believe that on the night between Friday and Saturday, hackers used this backdoor to access the bank’s network and install ransomware: Bank employees working weekend shifts discovered the attack when they couldn’t access their work files on Saturday.

‘ BancoEstado reported the incident to Chilean police, and on the same day, the Chilean government sent out a nationwide cyber-security alert warning about a ransomware campaign targeting the private sector ‘

While initially, the bank hoped to recover from the attack unnoticed, the damage was extensive, according to sources, with the ransomware encrypting the vast majority of internal servers and employee workstations: The bank initially disclosed the attack on Sunday, but as time went by, bank officials realized employees wouldn’t be able to work on Monday, and decided to keep branches closed, while they recover:
