Start Browser and Application Security PracticeA technician is troubleshooting a Windows 10 computer where the user cannot install a legitimate browser extension because the browser displays a warning that extensions from this source are not allowed. What setting is likely blocking the installation?
Explanation: Windows 10's S mode restricts app installations to the Microsoft Store, which also affects browser extensions. Disabling S mode or using a different browser that supports the extension is the solution.
A company policy requires that all web traffic from employee computers be filtered to block known malicious sites. You need to implement this without installing client software on each machine. Which approach should you use?
Explanation: A DNS-based content filter (like OpenDNS or a corporate DNS server) can block malicious domains without requiring client software. This is a scalable solution for network-wide filtering.
A user receives an email with a link that appears to be from their bank, asking them to verify their account. The link leads to a page that looks exactly like the bank's login page. What type of attack is this?
Explanation: This is a phishing attack, where the attacker creates a fake login page to steal credentials. Users should be trained to verify URLs and never enter credentials from email links.
During a security incident response, you discover that a user's browser has a rogue extension that exfiltrates data to a remote server. The extension was installed after the user clicked a fake update prompt on a website. What vulnerability was exploited?
Explanation: This is a social engineering attack where the user was tricked into installing malicious software. No technical vulnerability was exploited; the user's trust was manipulated.
A user reports that their web browser frequently redirects to an unfamiliar search engine and displays pop-up ads even when no tabs are open. What is the most likely cause of this behavior?
Explanation: This scenario describes classic symptoms of a browser hijacker, a type of malware that modifies browser settings without permission. The correct action is to scan and remove the malicious software using an anti-malware tool, as simply resetting settings or clearing caches may not remove the underlying infection.
