The Ragnar Locker ransomware gang has claimed an attack on the flag carrier of Portugal, TAP Air Portugal, disclosed by the airline after its systems were hit on Thursday night.
Even though TAP is yet to confirm if this was a ransomware attack, the Ragnar Locker ransomware gang posted a new entry on their data leak website today, claiming to be behind last week's cyberattack that hit TAP's network.
"Several days ago Tap Air Portugal made a press-release where they claimed with confidence that they successfully repelled the cyber attack and no data was compromised," the gang says.
Ragnar Locker ransomware payloads were first observed in attacks against several targets in late December 2019.
Attackers using Ragnar Locker ransomware have also encrypted the systems of Portuguese multinational energy giant Energias de Portugal and asked for a 1580 BTC ransom.
In March, the FBI said that Ragnar Locker ransomware had been deployed on the networks of at least 52 organizations from multiple US critical infrastructure sectors since April 2020.
