Cybercriminals have launched a ransomware attack against Telecom S.A., Argentina's largest telecommunications services provider, according to Cryptonews. They have set a Tuesday deadline for payment; if Telecom S.A. does not submit a payment by Tuesday, hackers will raise the ransom to $15 million.
Telecom S.A. is exploring solutions to the ransomware attack, Cryptonews noted. The company is asking its employees to temporarily avoid corporate network use and deactivate their computers and keep an eye out for suspicious files or emails from unknown recipients.
The Telecom S.A. ransomware attack likely occurred due to a malicious email attachment, Cryptonews stated. Furthermore, cybercriminals may have targeted Telecom S.A.'s Oracle Siebel customer relationship management (CRM) software during the attack.
In addition, hackers are demanding the Telecom S.A. ransom be paid in monero (XMR) cryptocurrency, Cryptonews reported. They also provided links to let Telecom S.A. know where it can buy XMR.
