Operation Crimson Palace: A Technical Deep Dive – Sophos News
Sophos Managed Detection and Response initiated a threat hunt across all customers after the detection of abuse of a vulnerable legitimate VMware executable (vmnat.exe) to perform dynamic link library (DLL) side-loading on one customer’s network. In a search for similar incidents in telemetry, MDR ultimately uncovered a complex, persistent cyberespionage campaign targeting a high-profile government organization in Southeast Asia. As described in the first part of this report, we identified at least three distinct clusters of intrusion activity present in the organization’s network from at least March 2023 through December 2023. The three security threat activity clusters—which we designated as Alpha (STAC1248), Bravo (STAC1870), and Charlie (STAC1305) – are assessed with high confidence to operate on behalf of Chinese state interests. In this continuation of our report, we will provide deeper technical analysis of the three activity clusters, including the tactics, techniques, and procedures (TTPs) used in the campaign, aligned to activity clusters where possible. We also provide additional technical details on prior compromises within the same organization that appear to be connected to the campaign.

Campagne d’exploitation d’une vulnérabilité affectant VMware ESXi
Le 03 février 2023, le CERT-FR a pris connaissance de campagnes d'attaque ciblant les hyperviseurs VMware ESXi dans le but d'y déployer un rançongiciel. Dans l'état actuel des investigations, ces campagnes d'attaque semblent exploiter la vulnérabilité CVE-2021-21974, pour laquelle un correctif est disponible depuis le 23 février 2021. Cette vulnérabilité affecte le service Service Location Protocol (SLP) et permet à un attaquant de réaliser une exploitation de code arbitraire à distance. Les systèmes actuellement visés seraient des hyperviseurs ESXi en version 6.x et antérieures à 6.7.

Mirai, RAR1Ransom, and GuardMiner – Multiple Malware Campaigns Target VMware Vulnerability
n April, VMware patched a vulnerability CVE-2022-22954. It causes server-side template injection because of the lack of sanitization on parameters “deviceUdid” and “devicetype”. It allows attackers to inject a payload and achieve remote code execution on VMware Workspace ONE Access and Identity Manager. FortiGuard Labs published Threat Signal Report about it and also developed IPS signature in April.
