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 risk actors.
Tracked beneath 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 side of cyber threats: the deliberate focusing on of cybersecurity distributors, who’re high-value targets resulting from their protecting roles and deep visibility into shopper environments.

SentinelLABS confirmed that regardless of the persistent efforts, SentinelOne’s infrastructure, software program, and {hardware} property remained uncompromised, because of strong monitoring and speedy response mechanisms.
The PurpleHaze cluster, lively between September and October 2024, included reconnaissance actions in opposition to SentinelOne’s Web-facing servers, alongside intrusions right into a South Asian authorities entity and a European media group.
Technical evaluation revealed using the GOREshell backdoor a variant of the open-source reverse_ssh software deployed with refined obfuscation methods 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 Providers 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 world 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 programs, highlighting the layered persistence and information exfiltration ways employed.
In keeping with the Report, SentinelLABS additionally documented using publicly accessible instruments like dsniff model 2.5a1 by The Hacker’s Selection neighborhood in these intrusions, marking a novel utility in APT contexts.
The report emphasizes the strategic intent behind focusing on cybersecurity corporations, 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 inside 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 risk panorama that calls for fixed vigilance and intelligence sharing.
