Microsoft warns of rise in credential stealing attacks by Russia-linked group: Midnight Blizzard/Nobelium/Cozy Bear threat group is focusing on governments, IT service providers, defence industry, among others
Microsoft warned last week that it has detected a notable increase in credential attack activity, pointing to the notorious threat actor known as Midnight Blizzard as the orchestrator.

What distinguishes these attacks is the clever use of residential proxy services to hide the source of their malicious activities, the software company said.

The threat actor Midnight Blizzard, formerly identified as Nobelium, has been associated with Russia and is also monitored under various names such as APT29, Cozy Bear, Iron Hemlock and The Dukes.

Gigabyte rolls out firmware update to close backdoor: Updated BIOS code and signature verification process for files downloaded from remote servers
Gigabyte has released new firmware to mitigate the potential security risk posed by a firmware issue affecting over 270 of its motherboard models.

The updates come after researchers at cybersecurity firm Eclypsium identified backdoor-like behaviour on certain Gigabyte motherboards.

It was discovered that the firmware on the identified models triggered and executed a Windows native executable during system startup, which downloaded and executed additional payloads.

Gigabyte has now released firmware updates for a range of motherboard series, including Intel 400/500/600/700 and AMD 400/500/600 series, in order to address these identified issues.

Additionally, the company has emphasised its commitment to enhancing security measures by implementing stricter security checks during the operating system boot process.

Microsoft Outage blamed on Russian Attack: Microsoft blames June outage on Russian DDoS
'Anonymous Sudan' is hiding its real identity

Microsoft has confirmed its services succumbed to DDoS attacks earlier this month, while a cybersecurity firm has pointed at Russia as the culprit.
The attacks hit Azure, Outlook and OneDrive over the course of three days, taking down services like Teams and Sharepoint Online.

The company gave early indications that the outages were the result of a DDoS attack when it attributed them to a "spike in network traffic". However, it wasn't until Friday that the company confirmed the news.

A post on the Microsoft Security Response Center says "This recent DDoS activity targeted layer 7 rather than layer 3 or 4... [The attacker] has been observed launching several types of layer 7 DDoS attack traffic."

Those types include HTTP(s) flood attacks; cache bypassing; and slowloris.

Microsoft to end Windows 10 support in October 2025: In a surprising move, Microsoft have announced it will stop support for Windows 10 on 14th October 2025.
Ending support means no more bug fixes, updates or technical support.
Microsoft is keen to move the operating system over to the service model (think Office365), where instead of owning the software, you rent it. (Software As a Service or SaaS).
Announcing the end of support for Windows 10 is another hint from Microsoft that it is now fully ready to launch a new version of Windows - although whether it will just drop the Windows 10 brand, or require a new purchase, is still unclear.
Although the company never mentioned maintaining the Windows 10 brand in perpetuity, it did promise to keep Windows current once licensed to a device at no cost.
