AUSCERT Week in Review for 1st October 2021
Greetings,
Today is International Coffee Day, an opportunity to celebrate the tasty brew that provides a kickstart to get us going or provides a boost to sustain us when needed. How do you prefer your coffee?
Earlier in the week, it was revealed that almost 10 million Android devices globally had been infected with malware delivered via GriftHorse apps.
The Register reported on the Trojan code that has already netted millions of dollars.
ZDNet advised many experts, including VMware and CISA, have been begging people to address the CVE-2021-22005 issue, a vulnerability with VMware vCenter, by updating their systems as soon as possible.
Microsoft rolled out a new feature to Exchange that will automatically install temporary mitigations that block active security flaws until an official patch is released by Microsoft.
The Record wrote about the proactive move by Microsoft with its first-of-its-kind security feature.
Lastly, we wanted to advise of some upcoming training that is being held in the last quarter of 2021, delivered remotely via Zoom. The courses will focus on Cyber Security Risk Management and Introduction to Cyber for IT Professionals.
Dates and further information can be found on the online booking portal or, by contacting us via email at training@auscert.org.au

The Victorian government has launched a new five-year cyber strategy that will see over AU$50 million be allocated towards bolstering the state’s cybersecurity resilience.
The cyber strategy will focus on three core missions that government has described as providing safe and reliable delivery of government services, creating a cyber safe place, and creating a “vibrant” cyber economy.
The strategy will be implemented through the state’s chief information security officer releasing annual mission delivery plans that outline specific activities associated with the three core missions. The CISO will develop this plan in consultation with relevant stakeholders across government, industry, and the community.
Microsoft adds novel feature to Exchange servers to allow it to deploy emergency temporary fixes

Author: The Record
Microsoft will soon roll out a new security feature for its Exchange email servers, which have been at the center of several hacking campaigns over the past two years.
Called the Microsoft Exchange Emergency Mitigation service, the new feature works by automatically installing temporary mitigations that block active exploitation of security flaws until Microsoft is ready to release official patches.
The Emergency Mitigation service will be enabled by default for all Exchange servers once they install the September 2021 Cumulative Updates for Exchange servers, which are shipping out soon, after Microsoft delayed their release last week to have more time to work on it.

Such schemes, referred to as “business email compromise,” often don’t get nearly the amount of attention or public awareness as ransomware and other forms of cybercrime, but the cumulative losses to businesses and individuals every year often dwarf what is seen in almost all other areas of digital crime.
According to the latest annual internet crime report from the FBI, they helped fuel a record account of complaints reported to authorities by the American public in 2020, with 19,369 complaints and adjusted losses of $1.8 billion attributed to BEC schemes alone.
