The first 0day of the week was reported by Microsoft's Threat Intelligence Center (MSTIC) on October 2nd. Exploitation chains observed in the wild used a malicious printer driver to escape Low Integrity Level sandboxes. The key nuance? This 0day bypassed Patch Tuesday’s August mitigations for a related bug (CVE-2024-38124). This week was not about theoretical risks

In this deep dive, we reconstruct the timeline, examine the technical nuances of the 0days disclosed, and analyze the hitlist methodology observed during the first week of October 2024. The week commencing October 1, 2024, saw three major 0day vulnerabilities added to the Known Exploited Vulnerabilities (KEV) catalog. Concurrently, threat intelligence feeds picked up a surge in "hitlist" chatter on underground forums—specifically targeting the transportation, energy, and legal sectors. Exploitation chains observed in the wild used a
