Incident Timeline
‎April 2026
The threat actor used the SPECTRE implant to deploy a Linux rootkit on Windows, bypassing endpoint detection and response (EDR) capabilities of EDR vendors.
infrastructure Windows
The Windows version is equipped to perform file operations, record keystrokes, take screenshots, download/upload files, execute shell commands, get running processes, terminate a specific process, get system information, set beacon sleep interval, modify file timestamps, inject shellcode, use process hollowing and Early Bird APC injection, kill EDR processes using the bring your own vulnerable driver (BYOVD) technique, delete itself from the host.
infrastructure Linux
The Linux version's instruction set, in contrast, only supports 29 commands that encompass file system manipulation, system and process reconnaissance, agent management, and unrestricted shell execution.
"Consequently, kernel-callback-dependent security products such as CrowdStrike Falcon, SentinelOne, Microsoft Defender, and other well-known EDR vendors are rendered completely blind to new process creations, thread creations, and image load events for the remainder of the session, successfully neutralizing EDR visibility on the target machine." SPECTRE's Linux variant follows more or less the same pattern, running a series of anti-sandbox checks before setting up a C2 connection.
"The Spectre backdoor loads the Linux Kernel rootkit, Specter, to prevent detection from security products."

Following successful anti-sandbox validation, SPECTRE beacons to its hardcoded C2 domain with a JSON payload, which is the same as the Windows version.
Rather than 45 commands in the Windows variant, the Linux version of SPECTRE only has 29 commands, none of which result in obfuscation or encryption.

Rather than 45 commands in the Windows variant, the Linux version of SPECTRE only has 29 commands, none of which result in obfuscation or encryption.
The Linux attacks, like in the case, leverage various known vulnerabilities to obtain an initial foothold, followed by abusing various known Local Privilege Escalation (LPE) exploits to escalate to root, including CVE-2022-0995 , CVE-2021-3156 , CVE-2015-5287 , CVE-2015-3246 , CVE-2010-3904 , and CVE-2022-0847 .
UAT-10147 Uses AI to Scale Server Attacks, Deploys SPECTRE With EDR Bypass and Linux Rootkit.
In one case, the threat actor is said to have successfully exploited a website and collected information about the victim host using Linux commands.
UAT-10147 is a highly capable Chinese-speaking intrusion actor operating a multi-platform post-exploitation ecosystem targeting IIS and Linux servers, combining search engine optimization (SEO) fraud monetization with advanced persistence and defense evasion techniques.
UAT-10147 deploys SPECTRE: A cross-platform implant with Linux rootkit and BYOVD capabilities.
The actor demonstrates operational maturity through the combined use of custom malware, open-source offensive tooling, Bring Your Own Virtual Driver (BYOVD) based EDR neutralization, Linux kernel rootkits, and sophisticated in-memory web shell deployment techniques.
Cisco Talos’ analysis of recovered source code suggests portions of the Linux rootkit development may have incorporated AI-assisted code generation workflows, highlighting the growing role of generative AI in accelerating offensive malware development.
In our previous blog , Cisco Talos documented how UAT-10147 operationalized AI-assisted exploitation workflows to compromise internet-facing IIS and Linux servers at scale.

Specter Linux rootkit  The SPECTRE backdoor loads the Linux Kernel rootkit, Specter, to prevent detection from security products.
Based on the SPECTRE Linux version we observed, the compiled artifact is deployed disguised as “acpi_pad.ko”.
Rather than patching the syscall table, the hook mechanism rootkit uses the Linux kernel's native “ftrace” instrumentation framework with “FTRACE_OPS_FL_IPMODIFY” to redirect execution at the function entry point of six syscall handlers:  hooked_tcp6_seq_show  hooked_tcp4_seq_show  hooked_tkill  hooked_tgkill  hooked_kill  hooked_getdents64  Because “ftrace” is a legitimate kernel debugging interface, this approach produces minimal noise in kernel integrity checks.
Meterpreter  Talos has observed UAT-10147 deploying reverse Meterpreter shells to maintain persistent access to compromised Linux hosts.
Noodle RAT  UAT-10147 also deployed Noodle RAT against targeted Linux servers, utilizing it as a final stage backdoor to ensure persistent access.

It then references a hardcoded, per-build offset table covering 13 Windows versions to calculate the exact kernel virtual addresses for PspCreateProcessNotifyRoutine, PspCreateThreadNotifyRoutine, and PspLoadImageNotifyRoutine.
Linux version  The SPECTRE Linux variant’s structure is the same as the Windows variant.
Following successful anti-sandbox validation, SPECTRE beacons to its hardcoded C2 domain with a JSON payload, which is the same as the Windows version.
Rather than 45 commands in the Windows variant, the Linux version of SPECTRE only has 29 commands, none of which result in obfuscation or encryption.

Affected Product
Cybersecurity researchers have disclosed details of a Chinese-speaking cybercrime group dubbed UAT-10147 that's targeting Windows and Linux web servers globally across the education, media, technology, and gaming sectors.
The Linux attacks, like in the case, leverage various known vulnerabilities to obtain an initial foothold, followed by abusing various known Local Privilege Escalation (LPE) exploits to escalate to root, including CVE-2022-0995 , CVE-2021-3156 , CVE-2015-5287 , CVE-2015-3246 , CVE-2010-3904 , and CVE-2022-0847 .
The Linux version's instruction set, in contrast, only supports 29 commands that encompass file system manipulation, system and process reconnaissance, agent management, and unrestricted shell execution.
UAT-10147 Uses AI to Scale Server Attacks, Deploys SPECTRE With EDR Bypass and Linux Rootkit.
In one case, the threat actor is said to have successfully exploited a website and collected information about the victim host using Linux commands.
"Consequently, kernel-callback-dependent security products such as CrowdStrike Falcon, SentinelOne, Microsoft Defender, and other well-known EDR vendors are rendered completely blind to new process creations, thread creations, and image load events for the remainder of the session, successfully neutralizing EDR visibility on the target machine." SPECTRE's Linux variant follows more or less the same pattern, running a series of anti-sandbox checks before setting up a C2 connection.
"The Spectre backdoor loads the Linux Kernel rootkit, Specter, to prevent detection from security products."
UAT-10147 is a highly capable Chinese-speaking intrusion actor operating a multi-platform post-exploitation ecosystem targeting IIS and Linux servers, combining search engine optimization (SEO) fraud monetization with advanced persistence and defense evasion techniques.
UAT-10147 deploys SPECTRE: A cross-platform implant with Linux rootkit and BYOVD capabilities.
The actor demonstrates operational maturity through the combined use of custom malware, open-source offensive tooling, Bring Your Own Virtual Driver (BYOVD) based EDR neutralization, Linux kernel rootkits, and sophisticated in-memory web shell deployment techniques.
Cisco Talos’ analysis of recovered source code suggests portions of the Linux rootkit development may have incorporated AI-assisted code generation workflows, highlighting the growing role of generative AI in accelerating offensive malware development.
In our previous blog , Cisco Talos documented how UAT-10147 operationalized AI-assisted exploitation workflows to compromise internet-facing IIS and Linux servers at scale.

Specter Linux rootkit  The SPECTRE backdoor loads the Linux Kernel rootkit, Specter, to prevent detection from security products.
Based on the SPECTRE Linux version we observed, the compiled artifact is deployed disguised as “acpi_pad.ko”.
Rather than patching the syscall table, the hook mechanism rootkit uses the Linux kernel's native “ftrace” instrumentation framework with “FTRACE_OPS_FL_IPMODIFY” to redirect execution at the function entry point of six syscall handlers:  hooked_tcp6_seq_show  hooked_tcp4_seq_show  hooked_tkill  hooked_tgkill  hooked_kill  hooked_getdents64  Because “ftrace” is a legitimate kernel debugging interface, this approach produces minimal noise in kernel integrity checks.
Meterpreter  Talos has observed UAT-10147 deploying reverse Meterpreter shells to maintain persistent access to compromised Linux hosts.
Noodle RAT  UAT-10147 also deployed Noodle RAT against targeted Linux servers, utilizing it as a final stage backdoor to ensure persistent access.
