Albania’s parliament said late Tuesday that it had been targeted by a “sophisticated” cyberattack aimed at deleting data and compromising several internal systems.

In a statement shared with local media, parliament said its main systems and official website remained operational but confirmed that internal email services used by the parliamentary administration had been temporarily suspended. The disruption affected both incoming and outgoing communications.

Local media reported that parliamentary staff and lawmakers were unable to access computers and email systems for several hours following the attack.

Authorities have not publicly attributed the incident, but earlier this week a hacker group known as Homeland Justice claimed responsibility, saying it had obtained internal communications involving Albanian lawmakers. The group also posted screenshots of what it said were leaked documents on its Telegram channel.

Albanian authorities have not publicly verified the hackers’ claims and the country’s cybersecurity agencies are still investigating the incident.

Homeland Justice has previously been linked by security researchers and Western officials to Iran’s Islamic Revolutionary Guard Corps (IRGC). The group has claimed responsibility for a series of cyberattacks against Albanian targets in recent years, including operations against the country’s parliament, national airline, telecommunications firms and national statistics agency.

The latest incident comes amid heightened security concerns in Albania following retaliatory actions by Iran against countries hosting U.S. military bases after the United States and Israel began bombing Tehran in recent weeks.

Many of the cyber operations attributed to Homeland Justice have been linked to Albania’s hosting of members of the Iranian opposition group Mujahedeen-e-Khalq (MEK), who are based in the coastal county of Durrës.

In a Telegram post on Tuesday, Homeland Justice said the latest cyberattack was retaliation for Albania’s support of MEK.

The claim follows recent statements by MEK leader Maryam Rajavi announcing the formation of what she described as a provisional government aimed at replacing Iran’s current leadership with a democratic republic.
