AusCERT Week in Review for 1st April 2021

Greetings,

Here we are, at the end of Quarter 1 2021. What a year it’s been for our sector so far! The wave of vulnerabilities and associated attacks we’ve observed has certainly kept all of us busy.

This week we saw an urgent out-of-band Apple security update for its iOS and iPadOS mobile operating system, see bulletin details below. We also witnessed Nine Media recovering from what's been described as a "significant and complex" cyber-attack, a timely prompt to re-visit “The Essential Eight” a prioritised list of mitigation strategies issued by the ACSC.

Last week, the AusCERT team were privileged to attend our first in-person conference event in over a year – BrisSEC21, an event hosted by the AISA Brisbane chapter. Our Director, Dr David Stockdale presented a talk on the theme of cybercrime at the event. An article based on this talk will be submitted to the next edition of the Women in Security magazine and we will share it when it’s published.

We look forward to our next event, our very own annual conference, AusCERT2021. On that note, members – a reminder that all nominated Primary and Organisation contact person(s) would have received details regarding your organisation’s member token(s), part of your AusCERT membership perks which allows you to attend our annual conference for free or as a partially subsidised delegate – please make sure you utilise the token(s) by 18 April. Conference registrations can be done via our website here.

AusCERT will maintain minimal coverage for the Easter holidays from Friday 2 April to Monday 5 April. AusCERT staff will be on-call for emergencies only and email will not be monitored during this time. Any AusCERT member with an emergency may contact on-call AusCERT staff on the AusCERT Incident Hotline, details available here.

Until next week, have a good long Easter weekend everyone. Stay safe and let’s keep up with our Covid-safe practices.
