NetWalker is a ransomware operation that mainly targets corporate computer networks and encrypts all Microsoft applications, including MS Office. After encrypting all the data available on the victim’s system, the attackers demand a ransom to exchange the password.
Argentinean news service Infobae reported that the attack caused all country border crossings to shut down for almost four hours. During this time, the authorities shut down all the computer networks used at their regional offices and checkpoints.
