Australia’s OPTUS suffers data breach

Source: AFP announce the first arrest linked to the Optus data breach. But it's not the original hacker — it's someone accused of exploiting leaked data - ABC News

What data was taken?

Optus says the stolen data includes names, email addresses, postal addresses, phone numbers, dates of birth, and for a portion of the affected customers, identification numbers including passport numbers, driver’s licence numbers and Medicare numbers.

The dump of records released by the forum user contained all this information.

How common is this method of attack?

“Unfortunately, it can be pretty common,” Josh Lemon, a digital forensics and cyber incident expert at SANS Institute, said. But he said attackers tended to not target a single organisation. They usually scan across the internet looking for known vulnerabilities and exploiting those vulnerabilities all at once, he said.

“So for a threat actor to specifically just go after [one company] is a little bit unique in that sense.”

More than 120 vulnerabilities disclosed as part of Microsoft Patch Tuesday

“Microsoft released its monthly security update Tuesday, disclosing more than 120 vulnerabilities across its line of products and software, the most in a single Patch Tuesday in four months. This batch of updates also includes a fix for a new vulnerability in the Microsoft Windows Support Diagnostic Tool (MSDT) that’s actively being exploited in the wild, according to Microsoft. MSDT was already the target of the so-called “Follina” zero-day vulnerability in June. Two of the important vulnerabilities CVE-2022-35743 and CVE-2022-34713, are remote code execution vulnerabilities in MSDT. However, only CVE-2022-34713 has been exploited in the wild and Microsoft considers “more likely” to be exploited.” – SANS @RISK
