SentinelLABS, a classy reconnaissance operation focusing on SentinelOne, a number one cybersecurity vendor, has been detailed as a part of a broader espionage marketing campaign linked to China-nexus menace actors.
Tracked below the exercise clusters PurpleHaze and ShadowPad, these operations spanned from July 2024 to March 2025, affecting over 70 organizations worldwide throughout sectors like authorities, media, manufacturing, finance, and telecommunications.
Persistent Threats from China-Nexus Actors Uncovered
The report sheds mild on a hardly ever mentioned facet of cyber threats: the deliberate focusing on of cybersecurity distributors, who’re high-value targets because of their protecting roles and deep visibility into consumer environments.

SentinelLABS confirmed that regardless of the persistent efforts, SentinelOne’s infrastructure, software program, and {hardware} belongings remained uncompromised, because of strong monitoring and speedy response mechanisms.
The PurpleHaze cluster, energetic between September and October 2024, included reconnaissance actions towards SentinelOne’s Web-facing servers, alongside intrusions right into a South Asian authorities entity and a European media group.
Technical evaluation revealed the usage of the GOREshell backdoor a variant of the open-source reverse_ssh device deployed with refined obfuscation strategies like Garble and UPX packing.
Infrastructure overlaps, such because the shared C2 area downloads.trendav[.]vip resolving to IP 142.93.214[.]219, linked these assaults to a China-operated Operational Relay Field (ORB) community, typically related to teams like APT15 and UNC5174, a suspected preliminary entry dealer for China’s Ministry of State Safety.
Cybersecurity Vendor Focusing on
The exploitation of zero-day vulnerabilities, together with CVE-2024-8963 and CVE-2024-8190 in Ivanti Cloud Companies Equipment, underscores the superior capabilities of those actors, who gained footholds days earlier than public disclosure.
Moreover, the ShadowPad malware, obfuscated with ScatterBrain, was deployed in a separate wave of assaults from June 2024 to March 2025, focusing on international entities and an IT logistics supplier linked to SentinelOne.
A notable occasion concerned the AppSov.exe pattern, executed by way of PowerShell to obtain malicious payloads from compromised inner techniques, highlighting the layered persistence and information exfiltration ways employed.
Based on the Report, SentinelLABS additionally documented the usage of publicly out there instruments like dsniff model 2.5a1 by The Hacker’s Selection group in these intrusions, marking a novel software in APT contexts.
The report emphasizes the strategic intent behind focusing on cybersecurity companies, aiming to disrupt protecting mechanisms and probably entry downstream entities.
By sharing detailed indicators of compromise (IOCs) and technical insights, SentinelLABS advocates for transparency and collaboration throughout the trade to counter such persistent threats.
The attribution to China-nexus actors with excessive confidence, mixed with the reuse of personal SSH keys throughout a number of campaigns, factors to a coordinated and evolving menace panorama that calls for fixed vigilance and intelligence sharing.
