DAGGER

DAGGER is a malware infection that exists in graphics and network cards. DAGGER runs on dedicated devices and attacks direct memory access (DMA). The attacks initiated by DAGGER targets host runtime memory using DMA provided to hardware devices. DAGGER attacks 32bit and 64bit Windows and Linux systems and can bypass memory address randomisation. DAGGER contains keylogger funtionalities and is able to update its attack behaviour during runtime via an out-of-band channel. DMA-based attacks launched from peripherals are able to compromise the host without exploiting vulnerabilities present in the operating system running on the host. DAGGER is a highly critical security threat to system security and integrity. Unfortunately, up to now no OS (operating system) utilizes security tools that can detect DMA-based attacks.
