//Week in review - 7 Oct 2022
Greetings,
It’s Cyber Security Awareness Month in October which, given the recent breadth and severity of data leaks seen in Australia, is an opportune reminder to be mindful of current threats and vulnerabilities.
Now in its seventh year, the BDO and AusCERT Cyber Security Survey allows organizations to benchmark their approach to cyber risk. The information provided will then provide the chance to assess and optimise organizational cyber security.
There’s also the chance to win one of two Apple Airpod Pros so be sure to complete your survey before Friday, November 18!
It was announced yesterday that a proposal by the federal government had been made to allow Australian banks temporary access to government identification details by telcos in the wake of the Optus data breach.
The move is to assist in preventing fraud, but banks would need to adhere to strict requirements to reduce the risk of further compromise of customer data.
This Monday, October 10 will see the next full moon, referred to as the Pink Moon, signifying the arrival of the first spring flowers.
Apart from the pink moon, the other October full moon names in the southern hemisphere are Egg Moon, Seed Moon, and Waking Moon whilst in the northern hemisphere, they will experience the Hunter’s Moon.
The name derives from a time when the full moon signified the time to start preparing for the coming winter by hunting animals and preserving meat. If you live north of the equator, be sure to learn how you can view one of the year’s most stunning celestial events!

[AusCERT Bulletin: ASB-2022.0191.2]
Microsoft today updated its mitigation measures for two recently disclosed and actively exploited zero-day vulnerabilities in its Exchange Server technology after researchers found its initial guidance could be easily bypassed.
Microsoft’s original mitigation for the two vulnerabilities — CVE-2022-41040 and CVE-2022-41082 — was to apply a blocking rule to a specific URL path using the URL Rewrite Module on IIS Server. According to the company, adding the string “.*autodiscover\.json.*\@.*Powershell.*” would help block known attack patterns against the vulnerabilities.

The term ‘data breach’ has, in the last few weeks, worked its way into everyday conversation in Australia, thanks mostly to the failings of Optus. But now, details have emerged of another data breach affecting the Aussie telco sector – this time, it’s Telstra and it is employees that are at risk.
Brought to our attention first by The Australian, Telstra reportedly sent out a memo to staff over the weekend informing them of the data breach. It has since been confirmed by Telstra, with a spokesman telling Gizmodo Australia that the data breach affecting a third party included “limited” Telstra employee information from 2017. It is understood the third party handled Telstra’s rewards program for staff.
