Wannacry ransomware attack: Industry experts offer their tips for prevention

Wannacry ransomware attack: Industry experts offer their tips for prevention (Security Tips and Advice)

Also known as Wannacry, this attack involved a major Windows vulnerability, which allowed attackers to access systems, encrypt data rendering it off-limits and demand a ransom payment to release said data. Andrew Morrison: WannaCry is clearly still a threat for the large number of unpatched systems. Bad actors can now easily detect unpatched systems and direct WannaCry at them to conduct targeted attacks. Dylan Owen: We can expect to see a rise in targeted attacks against systems that are difficult to patch, like air-gapped or industrial control systems. Companies must proactively patch their vulnerable systems. Since attacks like WannaCry use port 445 to identify vulnerabilities, companies should block its visibility from the internet.
