Detection & IOCsextracted from sources · hover to see the quote
- →Attack vector requires a user to open a specially crafted Microsoft Excel file; the Preview Pane is NOT an attack vector — file must be explicitly opened. ↗
- →Email-based delivery: attacker sends a specially crafted Excel file as an attachment and socially engineers the recipient into opening it. ↗
- →Web-based delivery: attacker hosts or compromises a website serving a specially crafted Excel file; no forced navigation — requires user to click a link. ↗
- →The vulnerability is triggered by improper handling of objects in memory within Microsoft Excel; focus memory-corruption/heap monitoring on Excel process when opening untrusted files. ↗
- →Preview Pane is confirmed NOT an attack vector — detections should focus on full file-open events in Excel, not preview rendering. ↗
- ·CVE-2020-0651 is distinct from the related Excel RCE CVEs CVE-2020-0650 and CVE-2020-0653, which share the same vulnerability class; ensure detections/patches target the correct CVE and are not conflated. ↗
- ·Exploitation likelihood is rated 'Less Likely' for both latest and older software releases, and there is no public exploit or known in-the-wild exploitation as of the advisory date. ↗

Microsoft Excel Remote Code Execution Vulnerability
Description: A remote code execution vulnerability exists in Microsoft Excel 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 wit

## 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
