Rising cyber threats
Cybersecurity expert Dinos Pastos discussed the increasing risks to critical infrastructure and digital systems in Cyprus during the Sigma programme “Mesimeri kai Kati”. He highlighted new cyber threats using SMS and social media to target citizens directly.
Iran-linked hacker groups
Pastos noted that Iran has developed groups of skilled hackers, some directly under state control and others operating independently to support governmental objectives. These groups have demonstrated both the capability and motivation to conduct cyberattacks to further political or military goals.
Targeting citizens directly
A common tactic involves sending misleading messages resembling official emergency alerts. Recipients are prompted to visit a website and download an app that appears legitimate but is malicious, designed to steal data or monitor users. Even with strong infrastructure, attacks often target the population itself via social media or messages.
Infrastructure vulnerabilities
Pastos emphasised that Cyprus’ digital infrastructure will always have vulnerabilities due to the rapidly evolving technological environment. Measures effective today may be insufficient tomorrow. Constant vigilance, timely updates, and coordinated responses are essential, with guidance provided centrally through government mechanisms or organisations such as Europol.
Preventive measures
In the past, Cyprus has mitigated cyberattacks by temporarily restricting external internet access, allowing systems to operate internally and limiting exposure to external threats. Pastos also highlighted risks from individuals with system access, noting cases of data misuse. He advised that anyone handling sensitive data remain particularly cautious, as they may become a target either accidentally or intentionally.
