Microsoft Teams: Social Engineering and Remote Access Abuse
1 rule 3 TTPsThreat actors are abusing Microsoft Teams external chat and email bombing to impersonate IT support and facilitate unauthorized remote access to corporate endpoints.
AnyDesk Arbitrary Code Execution Vulnerability
3 TTPsAnyDesk contains a vulnerability that allows a remote, unauthenticated attacker to execute arbitrary code with administrator privileges on affected Windows systems.
Detection of Unauthorized Remote Access Software Usage
1 TTPThis detection monitors for the creation of files associated with known remote access utilities, which adversaries frequently deploy to establish C2 channels and persistent access.
Detection of RMM Software Deployment via Internet-Originated MSI Files
1 TTPThis detection identifies the download and execution of Windows Installer (MSI) packages from the internet that result in the installation of remote monitoring and management (RMM) software used for persistent system access.
The Gentlemen Ransomware Group Activity
1 rule 3 TTPsThe Gentlemen ransomware group leverages VPN/firewall exploits to gain initial access, utilizes BYOVD techniques to disable security tools, and propagates ransomware via the NETLOGON share.
CVE-2026-9181: Unauthenticated Directory Traversal in ArcGIS Server
2 TTPs 1 IOCAn unauthenticated attacker can exploit CVE-2026-9181, a critical directory traversal vulnerability in ArcGIS Server versions 12.0 and prior, by sending crafted path parameters to access sensitive files, leading to unauthorized information disclosure.
Suspicious DNS Queries to Remote Monitoring and Management Domains from Non-Browser Processes
1 rule 193 IOCsThis brief details the detection of DNS queries targeting commonly abused Remote Monitoring and Management (RMM) or remote access software domains, originating from non-browser processes, which is a common tactic for command and control, persistence, and lateral movement by threat actors.
Suspicious Activity: Multiple Remote Management Tool Vendors on Same Host
1 TTPThis brief describes a behavioral detection for Windows hosts where two or more distinct remote monitoring and management (RMM) or remote-access tools from different vendors are observed starting processes within an eight-minute window, indicating potential compromise, shadow IT, or attacker staging of redundant access.
First Time Seen Remote Monitoring and Management Tool Detection
1 rule 3 TTPs 5 IOCsAdversaries are leveraging legitimate Remote Monitoring and Management (RMM) and remote access tools on Windows endpoints for command-and-control, persistence, and execution, with detection focusing on the first observed instance of these tools on a host.
Ransomware-as-a-Service (RaaS) Ecosystem: Affiliate Tradecraft and Initial Access Vectors
2 rules 1 TTPRansomware-as-a-service (RaaS) attacks leverage affiliates for initial access, persistence, and exfiltration, using varied techniques like compromised RDP, vulnerable VPNs, and rogue RMM tools, impacting multiple organizations in a single campaign.
Fox Tempest Malware-Signing-as-a-Service Disrupted
2 rules 2 TTPs 1 IOCMicrosoft disrupted a malware-signing-as-a-service (MSaaS) operation run by Fox Tempest that abused the Azure Artifact Signing service to generate fraudulent code-signing certificates, enabling malware to bypass security controls.
MuddyWater Disguises Cyber-Espionage as Chaos Ransomware Attack
2 rules 5 TTPsThe MuddyWater group is disguising its cyber-espionage operations as Chaos ransomware attacks, using Microsoft Teams social engineering for initial access and establishing persistence, likely to complicate attribution and mask their true objectives.
Trigona Ransomware Employing Custom Data Exfiltration Tool
2 rules 4 TTPs 1 IOCTrigona ransomware is using a custom data exfiltration tool named 'uploader_client.exe' to steal data from compromised environments, enhancing speed and evasion.
Multiple Remote Management Tool Vendors on Same Host
3 rulesThe presence of multiple remote monitoring and management (RMM) tools from different vendors on a single Windows host within a short time frame may indicate compromise, shadow IT, or attacker staging for redundant access.
Multiple Remote Management Tool Vendors on Same Host
2 rulesThis rule identifies Windows hosts where two or more distinct remote monitoring and management (RMM) or remote-access tool vendors are observed starting processes within the same eight-minute window, potentially indicating compromise, shadow IT, or attacker staging of redundant access.
Detection of Windows RMM Tool Execution
3 rules 1 TTPDetects process creation events indicative of remote management tools, potentially signifying legitimate use or malicious exploitation by threat actors abusing RMM software.
Multiple Remote Management Tool Vendors on Same Host
3 rulesThis detection identifies a Windows host where two or more distinct remote monitoring and management (RMM) or remote-access tool vendors are observed starting processes within the same eight-minute window, potentially indicating compromise, shadow IT, or attacker staging of redundant access.
