SANS is excited to announce the June issue of OUCH! This month, led by Guest Editor Johannes Ulrich, we discuss the WannaCry ransomware attack. With the recent outbreak of this worm, there have been a tremendous number of questions about malware and what people can do to defend themselves. This OUCH newsletter explains what WannaCry is and reinforces the key behaviors that defend against it and other malware attacks. Please share OUCH! with your family, friends, and coworkers.
