OTTAWA -- The federal privacy watchdog says inadequate testing, coding errors and poor monitoring of the beleaguered Phoenix federal pay system resulted in exposure of the personal information of public servants.

In his annual report tabled today, privacy commissioner Daniel Therrien found at least 11 breaches occurred and the personal information at issue included employee names and salary information.

Therrien says most of the vulnerabilities were government-wide, meaning the information of all employees in the Phoenix system at the time of each breach was at risk.

In some cases, the commissioner found, information could be changed and transactions could be conducted.

In addition, Therrien determined there may be lingering vulnerabilities that could lead to future breaches.

The Phoenix pay system has been riddled with other problems, leaving some public servants without pay cheques for many weeks.
