New Threat(s) Detected

The following detections were added to your Clear NDR Enterprise (formerly Stamus Security Platform) this past week:

 

TinyLoader (Loader)

Loaders are evolving malware that allow attackers to control compromised computers, with features like user-friendly interfaces and self-healing capabilities. They remain popular among cybercriminals due to their effectiveness.

TinyLoader - Malpedia |

• Total number of detection methods: 15
• Kill chain phase(s): command and control
• MITRE ATT&CK: T1071, T1041

 

CastleLoader (Loader)

CastleLoader is a loader malware that surfaced in early 2025, distributing information stealers and RATs through Cloudflare-themed phishing attacks and fake Github repositories.

CastleLoader - PRODAFT | CastleLoader - thehackernews |

• Total number of detection methods: 5
• Kill chain phase(s): command and control, actions on objectives, delivery
• MITRE ATT&CK: T1071, T1189
