Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability requires a user to open a specially crafted file with an affected version of Microsoft Office; the Preview Pane is NOT an attack vector, so detections should focus on file-open events rather than preview actions. ↗
- →Email-based delivery vector: monitor for Office documents delivered via email that are subsequently opened by an Office process, potentially leading to child process spawning or memory corruption indicators. ↗
- →Web-based delivery vector: monitor for Office documents downloaded from websites (including compromised sites hosting user-provided content) and opened by Office processes. ↗
- ·Preview Pane is explicitly confirmed NOT an attack vector; detection rules scoped to Preview Pane activity will not cover this CVE. ↗
- ·Exploit status at time of advisory was 'Exploited: No' and 'Publicly Disclosed: No', meaning no public PoC or in-the-wild samples were available to derive concrete file-based IOCs from the provided sources. ↗

CVE-2020-0652 [HIGH] Microsoft Office Memory Corruption Vulnerability
Microsoft Office Memory Corruption Vulnerability
Description: A remote code execution vulnerability exists in Microsoft Office software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Exploitation of the vulnerability requires that a user open a specially crafted file with

## Microsoft Patch Tuesday — Jan. 2020: Vulnerability disclosures and Snort coverage
By Jon Munshaw. Updated January 15th: Added an Advanced Custom Detection (ACD) signature for AMP that can be used to detect exploitation of CVE-2020-0601 by spoofing certificates masquerading as a Microsoft ECC Code Signing Certificate Authority.
Microsoft released its monthly security update today, disclosing vulnerabilities across many of its products and releasing corresponding updates. This month's Patch Tuesday covers 49 vulnerabilities, eight of which are considered critical.
This month's security update is particularly important for its disclosure of two vulnerabilities related to a core cryptographic component in all versions of Windows. CVE-2020-0601 could allow an attacker to use cryptography
