AusCERT Week in Review for 18th June 2021

Greetings,

This week, we shared our June 2021 edition of The Feed – the AusCERT membership newsletter. Members, be sure to check your inbox(es) for a copy of this newsletter to catch up on all things related to your AusCERT membership.

We’re pleased to share the following blog piece by our AusCERT2021 Diversity and Inclusion Champion – Phillip “Pip” Jenkinson from Baidam Solutions. Congratulations Pip, a well-deserved win! For those of you based in the Greater Brisbane area and are wanting to hear more about Pip and the work he does at Baidam Solutions, come and join us at our upcoming NAIDOC Week 2021 luncheon on Friday 2 July, 12 - 2pm. For further details and to RSVP, visit the AusCERT website here.

Last but not least, we’re proud to announce that there are currently 11 NEW Member Security Incident Notifications (MISNs) reports generated in the pipeline by our team of analysts - all drawn from the expertise of our various threat intelligence partners and resources. This is a pertinent reminder for members to keep your organisation's IPs and domains up to date on the AusCERT member portal to make sure you're able to receive these relevant MSINs as they come through! A recap of how this particular AusCERT service assists our members with mitigating cyber-attacks can be found here "How AusCERT helped its members tackle the recent Microsoft Exchange server critical ProxyLogon vulnerabilities and exploits."

Until next week everyone, have a great weekend.

The Secretary of the Department of Home Affairs, Mike Pezzullo, has spoken out against hacked organisations that refuse assistance from the Australian Signals Directorate, likening it to refusing to cooperate with an air crash investigation.
One such example was discussed in evidence to the Parliamentary Joint Committee on Intelligence and Security on Friday.
"It was a nationally-known case involving a nationally-known company that [ASD director-general Rachel Noble] and I are declining to name at this point," he said.
[...] However the unnamed company lawyered up, and it took a week for the ASD to get even basic network information.
