The authority last week sent an advisory, seen by Reuters, to security officers of shipping companies, banks and firms in the transport, telecommunications, health and energy sectors, a source at the authority said, adding that the move was pre-emptive. An Iranian-linked hacking group claimed ‌responsibility on March 11 for a cyberattack on U.S.-based medical device and services provider Stryker, according to messages posted to the group’s Telegram channel. Albania has also confirmed a cyberattack on the digital infrastructure of its parliament last week that local media said was by the Iran-linked, self-styled “Homeland Justice” group. Albanian authorities told Reuters that any attempt to compromise the country’s critical infrastructure has been repelled. The Greek advisory, marked “high-priority,” urged firms to perform the scans and inform security officers of a confirmed incident that affected an unnamed “large international organization” abroad. It listed indicators of possible compromise, including IP addresses, tools and malware, such as the VShell Remote Access Trojan. Anyone finding evidence of attack should immediately review their systems and block those IPs, it said. Two separate sources said at least two shipping companies have received the warning. Electronic interference with commercial ship navigation systems has surged in recent days around the Strait of Hormuz and the wider Gulf. All the sources asked not to be named because they were not authorized to speak to the media. The first two said Greece had yet to find evidence of a significant attack, although one of them said “some sort of activity” had been tracked. The Greek advisory said an investigation into the confirmed incident had pointed to an unidentified, sophisticated threat actor using two layers of infrastructure to scan activity, attempt unauthorized access, host malware or run command-and-control mechanisms and avoid being traced. The second source said that some of the IP addresses listed in the Greek advisory originated from Iran. In 2022, Albania cut diplomatic relations with Iran after a cyberattack against state institutions that it blamed on the Islamic Republic. On Tuesday, the Albanian parliament adopted a resolution declaring Iran a “sponsor of terrorism” and condemning cyberattacks carried out against Albanian institutions. Asked to comment on the latest attack, government spokesperson Manjola Hasa told Reuters the country has built one of the most advanced cyber defense systems in Europe and will keep strengthening its defenses.
