Copel suffers cyberattack with no impact on services

Brazilian state-run power and telecommunications utility Copel announced that it was targeted by a cyberattack on Monday the 1st. According to a filing sent to the Brazilian Securities and Exchange Commission (CVM), the incident caused instability in some of the company's servers.

Copel explained that its operating and protection systems detected the incident immediately. The company applied security protocols, which included suspending its computerized environment to protect information integrity. Measures to restore normal operations were taken while an evaluation of the attack remained ongoing.

Electricity supply and telecom services operated normally and were not affected by the incident. Copel noted that its systems remained intact, confirming there was no data leakage.

Copel joins other Brazilian energy companies that faced cyberattacks in recent months, including Energisa and Light. Experts cited in the report noted that the COVID-19 pandemic and remote work arrangements have increased system and network exposure across the sector.
