Block port 445 at the network perimeter to prevent lateral movement.
The exploit sends specially crafted packets to the target, causing a buffer overflow in the kernel. 654684.7z
Microsoft officially recommends disabling SMBv1 in favor of SMBv2 or SMBv3. Block port 445 at the network perimeter to
The attacker scans a target network for port 445 and verifies if SMBv1 is enabled. 654684.7z
A sophisticated kernel-mode backdoor/implant used to inject and execute shellcode.
The attacker sends a DLL or shellcode through DoublePulsar to gain a full interactive shell (e.g., Meterpreter). 🛡️ Mitigation & Defense
Look for unusual lsass.exe or services.exe behavior, which are common targets for shellcode injection.
