New TriBack Loader Evades EDR Using Signed Binaries and Win32 Callback APIs
A new shellcode loader, dubbed “TriBack Loader,” to a China-nexus intrusion cluster tracked as JadeProx, with the malware explicitly engineered to evade modern EDR by abusing signed binaries and uncommon Win32 callback APIs. Across at least four observed variants, the loader underpins simultaneous espionage campaigns in South-East Asia and Latin America, including targeting of a…

Microsoft Defender XDR Blind Spot Lets Public C2 Traffic Evade Detection Queries
Microsoft Defender XDR users may inadvertently overlook command-and-control (C2) traffic when searching for Internet-bound connections due to a specific behavior in how IP addresses are classified. This issue arises from Kusto Query Language (KQL) detections that depend solely on filtering by RemoteIPType == >>Public<< in the DeviceNetworkEvents table. As a result, traffic destined for public…

Hackers Use Cruciferra Crypter to Disable EDR and Deploy XWorm, Remcos, and AsyncRAT
Hackers are abusing the Cruciferra crypter-as-a-service to systematically turn off endpoint detection and response (EDR) tools and stealthily deploy XWorm, Remcos, AsyncRAT, and other commodity malware in email-driven campaigns targeting multiple sectors worldwide. By combining BYOVD-based driver abuse, indirect syscalls and a polymorphic encryption engine with more than 90 mix-and-match crypto routines, Cruciferra has rapidly…

SindriKit 1.3.0 Abuses Call Stack Spoofing to Bypass EDR Detection
SindriKit 1.3.0 introduces a significant advancement in evading Endpoint Detection and Response (EDR) systems by exploiting dynamic call stack spoofing. This method defeats telemetry that inspects kernel-transition call chains, going beyond just user-mode hooks. Previously, SindriKit 1.2.0 had already separated syscall invocations via indirect syscalls, redirecting to legitimate syscall return instructions in ntdll.dll to evade…

Hackers Use Vulnerable Windows Drivers to Kill EDR in Ransomware Attacks
Hackers increasingly rely on vulnerable, legitimately signed Windows drivers to neutralize endpoint defenses, turning defense evasion into a decisive phase of modern ransomware attacks. Over the past three years the Bring Your Own Vulnerable Driver (BYOVD) technique has migrated from research proof-of-concept into a commoditized, routinely deployed capability in ransomware-as-a-service toolkits. By abusing signed kernel…
