Let's take a closer look at the latest from the private health insurance company.
Medibank share price slumps amid cyber shutdown news
The Medibank share price is defying the market's gains this morning.
Meanwhile, the company is preparing to take its Medicare and ahm systems offline from 8:30pm AEDT tonight to strengthen its security protections and undertake maintenance. Its retail stores and customer contact centre will also close on Saturday.
It clarified there's been no suspicious activity detected since 12 October and the company apologised for any inconvenience caused by this weekend's works. Continuing:
This is the next necessary phase of our ongoing work to further safeguard our network, called 'Operation Safeguard'.
Since the cybercrime we have bolstered existing monitoring, added further detection and forensics capability across the Medibank system and network, and have scaled up analytical support via specialist third parties.
IT security experts from Microsoft will be onsite at the company's Melbourne headquarters to complete the operation, which has been in the planning stages for several weeks.
