Iranian cyberattack on power plant was a ‘warning shot’

Hackers prompted fresh fears of Tehran’s appetite and capacity to target Britain’s critical infrastructure

 A cyberattack that shut down a small power facility in the UK last month
has been described by security officials as a “warning shot” by Iran
that sent a message about its ability to attack critical British national
infrastructure.

Hackers affiliated with the Iranian regime were behind the
attack at an undisclosed power plant, which disabled it for four days. The
incident was reported to the National Cyber Security Centre (NCSC), an arm
of GCHQ, but it did not receive any reports of power cuts in relation to
the cyberattack.

A government source told the Sunday Telegraph: “We have
thresholds for important generators to legally notify us of cyber activity,
and this site is nowhere near. It’s a very small-scale site, less than a
rounding error compared to grid capacity.” However, it has prompted fresh
fears of Iran’s appetite and capacity to target Britain’s critical
infrastructure.
