In DNS attacks, which type involves registering an elapsed domain name?

The type of DNS attack that involves registering an elapsed domain name is known as Domain Snipping. This process typically occurs when a domain name that has expired is quickly registered by another individual or entity before its original owner has a chance to renew it. This can be particularly strategic if the domain has a significant level of traffic or brand association, allowing the new registrant to take advantage of the prior reputation or user base of the domain.

Domain Snipping usually capitalizes on the time window when the domain expires and becomes available for registration. The intent can vary, from reselling the domain at a premium to leveraging it for malicious purposes or advertising.

The other choices relate to different concepts. For instance, Domain Hijacking refers to the unauthorized transfer of a domain name from the rightful owner to another party, while DNS Poisoning involves corrupting the DNS cache with false entries to redirect users. Cybersquatting involves registering domain names that are identical or confusingly similar to trademarks or well-known brands, usually with the intent to sell the domain back to the trademark owners at an inflated price.
