Detection & IOCsextracted from sources · hover to see the quote
- →Exploitation requires the victim to open a malicious Microsoft Office Project file on a system where the 'Block macros from running in Office files from the Internet' policy is disabled AND VBA Macro Notification Settings are not enabled — detect opening of .mpp or Office Project files sourced from the internet on systems with these policies disabled ↗
- →Monitor for VBA macro execution spawned from Microsoft Project (winproj.exe) processes, especially where the parent process involves files downloaded from the internet (Mark-of-the-Web bypass context) ↗
- →Alert on CVE-2024-38189 exploitation attempts: this vulnerability is confirmed actively exploited in the wild (Exploit Status: Exploited:Yes, Latest Software Release: Exploitation Detected) ↗
- →In email attack scenarios, watch for spearphishing emails delivering Microsoft Office Project files (.mpp) as attachments with social engineering lures to open them ↗
- →In web-based attack scenarios, monitor for Microsoft Project files downloaded from external/untrusted websites, particularly where the site hosts user-provided content ↗
- ·Exploitation only succeeds when BOTH the 'Block macros from running in Office files from the Internet' policy is disabled AND VBA Macro Notification Settings are not enabled; systems with either control properly configured are protected ↗
- ·The Preview Pane is NOT an attack vector; user must actively open the malicious file for exploitation to occur ↗
- ·As a mitigation alternative to patching, enabling VBA Macro Notification Settings can protect systems even if the 'Block macros from internet' policy remains disabled ↗

FAQ: How could an attacker exploit this vulnerability?
Exploitation requires the victim to open a malicious Microsoft Office Project file on a system where the Block macros from running in Office files from the Internet policy is disabled and VBA Macro Notification Settings are not enabled allowing the attacker to perform remote code execution.
In an email attack scenario, an attacker could send the malicious file to the victim and convince them to open the file.
In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a malicious file designed to exploit the vulnerability.
An attacker would have no way to force the victim to visit the

[HIGH] Six 0-Days Lead Microsoft’s August 2024 Patch Push
Microsoft today released updates to fix at least 90 security vulnerabilities in Windows and related software, including a whopping six zero-day flaws that are already being actively exploited by attackers.

This month’s bundle of update joy from Redmond includes patches for security holes in Office , .NET , Visual Studio , Azure , Co-Pilot , Microsoft Dynamics , Teams , Secure Boot, and of course Windows itself. Of the six zero-day weaknesses Microsoft addressed this month, half are local privilege escalation vulnerabilities — meaning they are primarily useful for attackers when combined with other flaws or access.
CVE-2024-38106 , CVE-2024-38107 and CVE-2024-38193 all allow an attacker to gain SYSTEM level privileges on a vulnerable machine, although the vulnerabili
