Rockstar defense required against PurpleHaze

Even the most battle-hardened defenders sometimes find themselves in the crosshairs.
SentinelOne, one of the world’s leading cybersecurity vendors, recently revealed it was targeted by a sophisticated cyberespionage campaign attributed to a China-linked group dubbed PurpleHaze.
Rather than breaching SentinelOne directly, the attackers compromised a logistics company linked to the vendor, using it as a launchpad to surveil both SentinelOne and its high-value clients.
PurpleHaze deployed an arsenal worthy of the backstage chaos of a Hendrix concert: ShadowPad, GoReShell, and stealthy, rapidly shifting ORB networks.
Excuse Me While I Sweep the Sky
The scope of PurpleHaze’s operation was vast.
The group targeted more than 70 organizations across critical sectors: ministries, telecommunications providers, banks, research labs, and manufacturers.
Among these, the logistics partner tied to SentinelOne became a silent but strategic entry point.
Once inside, PurpleHaze moved stealthily from sector to sector, exfiltrating intelligence, credentials, and mapping future access routes to enable potential follow-on operations.
Don’t Know If It’s Day or Night, Breach in Sight
The breach procedure orchestrated by PurpleHaze combined precision with stealth.
Initial access was achieved by exploiting an N-day vulnerability in CheckPoint gateways—a known flaw for which patches existed but which remained unpatched in some environments.
Once inside, PurpleHaze deployed GoReShell, a Go-based backdoor leveraging reverse SSH connections, alongside a version of ShadowPad obfuscated using a bespoke compiler known as ScatterBrain.
The attackers moved laterally across compromised environments by using ORB (Operational Relay Box) networks, infrastructures designed to remain dynamic, evasive, and difficult to trace.
Through these mechanisms, they were able to steal credentials, exfiltrate internal documents and communications, and possibly obtain security vendor tooling that could aid future operations.
Purple Haze All Around, Lock It Down
The PurpleHaze campaign highlights a critical reality: even security vendors are prime targets—not just for the data they hold, but for the insights they offer into protecting thousands of environments.
Organizations must assume that third-party connections are potential breach points and take aggressive steps to defend them.
Key defensive measures include:
Securing vendor access with the same rigor applied to internal assets.
Patching N-day vulnerabilities immediately to deny attackers easy entry points.
Implementing deep malware detection capable of spotting obfuscated threats like ScatterBrain-hidden payloads.
Monitoring lateral movement across relay infrastructures like ORB networks.
Restricting external beaconing and carefully segmenting third-party connections from critical systems.
The haze may spread fast, but a rockstar defense—built on vigilance, speed, and deep awareness—can hold the line before the next solo begins.
