Transposed URL Attack Vector

C.

The attack vector used to infect the devices is most likely "Typo squatting", also known as "URL hijacking".

Typo squatting is a type of cyber attack in which an attacker registers a domain name that is similar to a legitimate domain name, but contains a common typing error such as a misspelled word or transposed letters. The goal is to trick users who accidentally mistype the legitimate domain name into visiting the attacker's website instead, which can be used to spread malware, steal sensitive information, or launch other types of attacks.

In this case, the fact that several infected devices attempted to access a URL that was similar to the company name but with two letters transposed suggests that the attackers were using typo squatting to lure users into visiting their malicious website. It's also possible that the attackers were using DNS poisoning to redirect traffic from the legitimate website to their own, but the fact that the URL was similar to the company name suggests that typo squatting is the more likely explanation.

Cross-site scripting (XSS) is a different type of attack that involves injecting malicious code into a legitimate website to steal information or launch attacks on users who visit the site. While XSS attacks can be used to redirect users to a malicious website, the fact that the URL in this case was similar to the company name suggests that typo squatting is a more likely explanation.

DNS poisoning is a type of attack in which an attacker redirects DNS queries to a different IP address, usually with the goal of directing traffic to a malicious website or stealing sensitive information. While DNS poisoning can be used in conjunction with typo squatting or URL hijacking to redirect users to a malicious website, the fact that the URL in this case was similar to the company name suggests that typo squatting is a more likely explanation.
