//Week in review - 11 Nov 2022


AusCERT is seeking a new team member in our security systems admin and development area to lead engineering efforts and coordinate projects across our Analyst Team. If you're interested in security automation, infrastructure-as-a-service and cybersecurity-specific open source projects such as MISP, apply now – applications close this Sunday!

AusCERT’s Senior Manager, Mike Holm delivered a presentation on how to digest MISP data and draw meaningful conclusions from it during the 2022 AHECS Cybersecurity Summit held on the 7th-9th November in Canberra. The AHECS Cybersecurity Summit is a conference developed by the sector with a focus on the Higher Education and Research Cybersecurity, Identity Management and Privacy Community.

In Cyber security news this week, criminals released files on a dark web forum that are believed to contain stolen Medibank customer data. Australian Federal Police announced the expansion of Operation Guardian to protect Medibank Private customers whose personal data was unlawfully released to the internet. Operation Guardian was set up in September this year to deliver specialised protection to current and former Optus customers from identity crime and financial fraud following the Optus cybercrime incident.

AusCERT advises its members who are impacted by the recent data breaches to be alert for any phishing scams via email, texts, voice calls or post and verify any communications received to ensure that they are from a legitimate source.

In other news this week, our celestial neighbour glowed a spectacular red colour as the last total lunar eclipse for three years illuminated the sky on Tuesday night. While most parts of Australia had a clear view of the total lunar eclipse, the stargazers from our neighbours across the ditch had the most spectacular full show. The next total lunar eclipse is expected to grace our skies on March 14, 2025.

Last but not least, AusCERT acknowledges Remembrance Day and remembers the armed forces members who gave their lives in the line of duty to protect the nation.

Have a good weekend!

A number of phishing campaigns are leveraging the decentralized Interplanetary Filesystem (IPFS) network to host malware, phishing kit infrastructure, and facilitate other attacks.
"Multiple malware families are currently being hosted within IPFS and retrieved during the initial stages of malware attacks," Cisco Talos researcher Edmund Brumaghin said in an analysis shared with The Hacker News.
The research mirrors similar findings from Trustwave SpiderLabs in July 2022, which found more than 3,000 emails containing IPFS phishing URLs as an attack vector, calling IPFS the new "hotbed" for hosting phishing sites.
