Ragnar Locker ransomware claims attack on Portugal’s flag airline

Published

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.

The company said the attack was blocked and added that it found no evidence indicating the attackers gained access to customer information stored on impacted servers.

“TAP was the target of a cyber-attack, now blocked. Operational integrity is guaranteed,” the airline operator revealed in a statement on Friday via its official Twitter account.

“No facts have been found that allow us to conclude that there has been improper access to customer data. The website and app still have some instability.”

On Monday, the airline also published an alert saying that its website and app are unable because of the Thursday cyberattack.

It also added that customers could book flights, manage previously made bookings, and check in and download their boarding passes without logging in.

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 (EDP) and asked for a 1580 BTC ransom (the equivalent of more than $10 million at the time).

A list of Ragnar Locker’s past victims also includes Japanese game maker Capcom, computer chip manufacturer ADATA, and aviation giant Dassault Falcon.

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.

TAP (short for Transportes Aéreos Portugueses) is the largest airline in Portugal, accounting for more than 50% of arrivals and departures at the Lisbon International Airport in 2019.

TAP Air Portugal didn’t reply to a request for comment when BleepingComputer reached out earlier today.
