Irish cybersecurity chief warns on Iran-linked attacks

Summary

Ireland's cybersecurity chief has said it is entirely possible we could see more Iran-linked cyberattacks. Last week, the Cork base of medical technology company Stryker was impacted by a global cyberattack targeting the firm's operations. Handala, an Iran-linked hacking group, claimed responsibility. Richard Browne, Director of the National Cyber Security Centre (NCSC), said the Iran conflict means the cyber risk level for Ireland has increased, but not dramatically. "We're heavily dependent on a systematic, global network of services and infrastructure," Dr Browne said. "We saw that in Stryker, where an entity based in the US had an incident in the US that had an impact here. "That kind of thing is entirely possible in a whole range of other areas and that's the most pressing risk we have. "There are other issues. It's entirely possible we'd see hacktivism and you might see denial-of-service attacks." "But we don't see it as particularly likely that critical infrastructure or Government would be targeted here directly," he added. Dr Browne said he thinks it is a given that Iran-linked hackers will try to target other US companies, which could have implications in Ireland.

She said they have seen a big increase in cybercriminal activity since the escalation of the Iran conflict. "We have seen a lot of new activity, a lot of phishing, a lot of credentials theft, exploitation of exposed systems and online propaganda," Ms Saceanu said. "It's very much in line with how Iran-linked and Iran-aligned actors have been behaving in previous periods of geopolitical tension," she added. The cyber warfare is not just coming from the Iranian side. Long before the first missiles of Operation Epic Fury were fired, US cyber teams disrupted Iranian communications networks. The Financial Times reported that CCTV and traffic cameras had been hacked by Israel to track Iranian leaders.

Iran hits US targets in the region as Washington probes wedding strike

○ 1 source

Oil prices rose this week as conflict intensified in the six-month war, with Iran reportedly maintaining control of the Strait of Hormuz while the US presses a counter-blockade of Iranian ports. Iranian authorities claimed to have targeted US military assets in Kuwait and the UAE, though Kuwait confirmed intercepting a missile and drone attack on its air base, while the UAE reported no evidence of an attack on its own facilities.

These exchanges followed Iran’s attribution of a deadly wedding strike in Kuhestak to the US, a claim US Vice President JD Vance stated is currently under investigation but disputed by Washington.
