The answer, our researchers discovered, is that so-called active adversaries might be able to shake loose at least some queued-up data from at least least some access points. The researchers figured out various ways of tricking some access points into releasing those queued-up network packets.
Microsoft has released a script to make it easier to patch a BitLocker bypass security vulnerability in the Windows Recovery Environment. This PowerShell script simplifies the process of securing WinRE images against attempts to exploit the CVE-2022-41099 flaw that enables attackers to bypass the BitLocker Device Encryption feature system storage devices.
A new phishing campaign targets organizations in Eastern European countries with the Remcos RAT malware with aid from an old Windows User Account Control bypass discovered over two years ago.

BlackLotus, a UEFI bootkit that's sold on hacking forums for about $5,000, can now bypass Secure Boot, making it the first known malware to run on Windows systems even with the firmware security feature enabled. Secure Boot is supposed to prevent devices from running unauthorized software on Microsoft machines.
A stealthy Unified Extensible Firmware Interface bootkit called BlackLotus has become the first publicly known malware capable of bypassing Secure Boot defenses, making it a potent threat in the cyber landscape. "This bootkit can run even on fully up-to-date Windows 11 systems with UEFI Secure Boot enabled," Slovak cybersecurity company ESET said in a report shared with The Hacker News.
Given these dynamics and the massive market opportunities for cybersecurity professionals, talent churn poses a significant threat to security teams. Gartner research shows that compliance-centric cybersecurity programs, low executive support, and subpar industry-level maturity are all indicators of an organization that does not view security risk management as critical to business success.
Brave Browser version 1.47 was released yesterday, adding the Snowflake extension in the software's settings, enabling users to turn their devices into proxies that help users in censored countries connect to Tor.

Red Balloon Security disclosed multiple, critical architectural vulnerabilities in the Siemens SIMATIC and SIPLUS S7-1500 Series PLC that allow for bypass of all protected boot features. Exploitation of these vulnerabilities could allow offline attackers to generate arbitrary encrypted firmware that are bootable on all Siemens S7-1500 series PLC CPU modules.
A financially motivated threat actor tracked as Scattered Spider was observed attempting to deploy Intel Ethernet diagnostics drivers in a BYOVD attack to evade detection from EDR security products. The BYOVD technique involves threat actors using a kernel-mode driver known to be vulnerable to exploits as part of their attacks to gain higher privileges in Windows.
