Inside Apple: How macOS attacks are evolving
blog.malwarebytes.com/malwarebytes-news/2021/10/inside-apple-how-macos-attacks-are-evolving/ The start of fall 2021 saw the fourth Objective by the Sea (OBTS) security conference, which is the only security conference to focus exclusively on Apples ecosystem. As such, it draws many of the top minds in the field. This year, those minds, having been starved of a good security conference for so long, were primed and ready to share all kinds of good information. Conferences like this are important for understanding how attackers and their methods are evolving. Like all operating systems, macOS presents a moving target to attackers as it acquires new features and new forms of protection over time.
Azure network security helps reduce cost and risk according to Forrester TEI study
www.microsoft.com/security/blog/2021/10/12/azure-network-security-helps-reduce-cost-and-risk-according-to-forrester-tei-study/ As organizations move their computing from on-premises to the cloud, they realize that leveraging cloud-native security tools can provide additional cost savings and business benefits to their security infrastructure.

MysterySnail attacks with Windows zero-day
securelist.com/mysterysnail-attacks-with-windows-zero-day/104509/ In late August and early September 2021, Kaspersky technologies detected attacks with the use of an elevation of privilege exploit on multiple Microsoft Windows servers. The exploit had numerous debug strings from an older, publicly known exploit for vulnerability CVE-2016-3309, but closer analysis revealed that it was a zero-day. We discovered that it was using a previously unknown vulnerability in the Win32k driver and exploitation relies heavily on a technique to leak the base addresses of kernel modules.

Business as usual for Azure customers despite 2.4 Tbps DDoS attack
azure.microsoft.com/en-us/blog/business-as-usual-for-azure-customers-despite-24-tbps-ddos-attack/ In early August, we shared Azures Distributed Denial-of-Service (DDoS) attack trends for the first half of 2021. We reported a 25 percent increase in the number of attacks compared to Q4 of 2020, albeit a decline in maximum attack throughput, from one terabyte per second (Tbps) in Q3 of 2020 to 625 Mbps in the first half of 2021. The last week of August, we observed a 2.4 Tbps DDoS attack targeting an Azure customer in Europe. This is 140 percent higher than 2020s 1 Tbps attack and higher than any network volumetric event previously detected on Azure.

Why Choke-Point Analysis Is Essential in Active Directory Security
www.darkreading.com/application-security/why-choke-point-analysis-is-essential-in-active-directory-security Attackers that want to steal data, deploy ransomware, or conduct espionage must go through a series of steps, from initial access through establishing persistence and lateral movement to eventually exfiltrating the data. Abusing identity attack paths in Microsoft Active Directory (AD) is a popular method for attackers to accomplish several of these steps, including achieving persistence, privilege escalation, defensive evasion, credential access, discovery, and lateral movement.

Why does the internet keep breaking?
www.bbc.com/news/business-58873472 I doubt Mark Zuckerberg reads the comments people leave on his Facebook posts. But, if he did, it would take him approximately 145 days, without sleep, to wade through the deluge of comments left for him after he apologised for the meltdown of services last week. “Sorry for the disruption today” the Facebook founder and chief executive posted, following almost six hours of Facebook, WhatsApp and Instagram being offline. Facebook blamed a routine maintenance job for the disruption – its engineers had issued a command that unintentionally disconnected Facebook data centres from the wider internet.
