Scattered Spider is a financially motivated cybercriminal threat actor active since at least 2022. Also tracked as Octo Tempest, UNC3944, 0ktapus, Muddled Libra, Scatter Swine, Star Fraud, Roasted 0ktapus, Storm-0875, and DEV-0971, it is known for sophisticated English-language social engineering, particularly vishing directed at IT help desks. The group impersonates support personnel to induce credential resets, enroll attacker-controlled MFA factors, bypass MFA protections, and obtain initial access. It has conducted SIM-swapping operations, including through alleged bribery or manipulation of telecommunications personnel, and has used SMS phishing and adversary-in-the-middle techniques. Scattered Spider has targeted telecommunications providers, business-process-outsourcing organizations, major retailers, airlines, and large enterprises. Publicly reported victims include MGM Resorts, Caesars Entertainment, Marks & Spencer, Co-op, Harrods, Hawaiian Airlines, WestJet, and Qantas. The group uses information stealers, remote-access tooling, and ransomware, searches compromised environments for credential material, and exfiltrates data through cloud-storage services. It conducts data-theft extortion and ransomware activity and has been associated with the ALPHV/BlackCat affiliate ecosystem.

Scattered Spider is known to exploit CVE-2015-2291 which is a vulnerability in the Intel Ethernet diagnostics driver for Windows (iqvw64.sys) that allows local users to cause a denial of service or possibly execute arbitrary code with kernel privileges... Scattered Spider exploited CVE-2015-2291 to deploy a malicious kernel driver in the Intel Ethernet diagnostics driver for Windows (iqvw64.sys).
The CVE-2025-61882 campaign is particularly instructive. CrowdStrike assessed with moderate confidence that GRACEFUL SPIDER was involved in mass exploitation of that vulnerability... Exploitation had begun nearly two months earlier on August 9, 2025, well before Oracle's public disclosure.
Additionally, Scattered Spider has exploited CVE-2021-35464 which is a flaw in the ForgeRock AM server. ForgeRock AM server versions before 7.0 have a Java deserialization vulnerability in the jato.pageSession parameter on multiple pages... remote code execution can be triggered by sending a single crafted /ccversion/* request to the server.
This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
This analytic identifies potential exploitation attempts of ProxyShell (CVE-2021-34473, CVE-2021-34523, CVE-2021-31207) and ProxyNotShell (CVE-2022-41040, CVE-2022-41082) vulnerabilities in Microsoft Exchange Server.
