[QUOTE="Andy Ful, post: 1121139, member: 32260"] [B][SIZE=5]Laptop in an Internet cafe.[/SIZE][/B] In another thread, I was asked about the computer security setup suitable for use in Internet cafes. The laptop in the Internet cafe is more vulnerable than at home (router with NAT). There are two main dangers: [LIST=1] [*]Man-In-The-Middle (MITM) attacks. [*]Exploitation of vulnerable network protocols and services exposed via open ports. [/LIST] If the laptop is unpatched, the attacker can sign into the Wi-Fi network in the cafe and use popular penetration testing tools to exploit it pretty quickly. Protecting unpatched laptops is challenging and warrants a discussion in its own right. Fortunately, Windows 10+ performs system updates automatically. Furthermore, Microsoft quickly patches system vulnerabilities, before new exploits are added to popular penetration testing tools. So, the default setup of Windows 10+ mainly covers the danger from point 2. We are left with MITM attacks.

[*]Spying, phishing, identity theft, etc. [/LIST] Cautious users can follow some healthy habits to avoid most problems: [URL='https://www.itgovernance.eu/blog/en/how-to-defend-against-man-in-the-middle-attacks']What is a MITM Attack?
