Two Southwestern Ontario hospitals, connected by shared
infrastructure, were struck Thursday by cyber attacks, the latest in a
string of similar incursions in the area this week.

The Listowel Wingham Hospitals Alliance, which oversees the Listowel
and Wingham hospitals, confirmed Thursday it was experiencing network
issues as a result of what appears to be a cyber attack.

Karl Ellis, the hospital president and CEO, said the issues began
Wednesday night and were uncovered during regular monitoring.

As a precautionary measure, the hospital has take its networks offline

The apparent cyber attack is affecting both hospitals, Ellis said, as
there is shared infrastructure between the two facilities.

The City of Woodstock is facing its own cyber attack, which began on
Saturday morning. Woodstock police also said they were attacked early

Stratford city hall was the target of a ransomware attack in April
and, last week, officials acknowledged they paid about $75,000 in
Bitcoin, a digital currency, for the hacker to back off.
