Cautious optimism from tech experts, in the wake of this week's ManageMyHealth cyber attack

On Thursday, the online health portal confirmed unauthorised access to its systems - which connect patients with clinicians and store private health records.

It says the breach has now been contained, and the flaws in its code fixed.

Gorilla Technology Chief Executive Paul Spain, says the incident may not have been as severe as initially feared, and he's hopeful no data will be leaked.

He says it's now clear that only the Health Documents part of the app was accessed, not the full range of ManageMyHealth data.
