Threat actors are increasingly exploiting Active Directory replication mechanisms to steal password hashes without directly compromising a domain controller. This technique, known as DCSync, allows attackers with privileged domain credentials to impersonate a legitimate domain controller and request sensitive directory replication data. Unlike noisy attacks that use malware on servers or attempt to extract credentials […]

A newly documented Windows attack pattern, dubbed Bring Your Own Trusted Caller (BYOTC), shows how attackers can bypass driver-level authorization controls without exploiting a traditional memory-corruption flaw. Instead of attacking a privileged kernel driver directly, an adversary compromises or abuses the legitimate user-mode application that the driver already trusts. The technique expands on the well-known […]

A malicious ScreenConnect campaign in which rogue remote-access clients do more than provide attackers with hands-on control: modified clients can automatically push a multi-stage VBScript malware chain to newly connected Windows endpoints. Once deployed, the clients repeatedly spawned wscript.exe to execute four scripts 1.vbs, 2.vbs, 3.vbs, and 4.vbs from ScreenConnect-related temporary locations. The behavior is […]
