It's considered one of Argentina's largest cyber attacks.
Over the weekend, ransomware gang REvil took control of an internet service provider (ISP), infecting the internal network.
The attack began with a domain admin and spread throughout the company network with extensive damage.
While internet connections are still running for the ISP's customers, many of the official websites are down.
The ransomware demand is a staggering $7.5 million, set to double every three days.
ZDNet explains how Telecom Argentina responded to the attack:
"According to images shared online, the ISP appears to have detected the intrusion right away and has been actively warning employees through internal alerts to limit their interaction with the corporate network, not to connect to its internal VPN network, and not open emails containing archive files.
Telecom Argentina has not commented on the incident, when contacted by local press, and did not say if it intends to pay the ransom demand."
Particularly during a time where telecommunication services are vital to preserving remote work and social connections, an attack like this carries damaging consequences.
