Tactic or Technique: Lookalike domain

Attackers register domains that closely resemble legitimate ones to trick you into thinking you're visiting or interacting with a trusted site. These lookalike domains use small visual or typographic changes, like swapping “m” for “rn,” misspelling a brand name, or using characters from other alphabets that look identical.
A link may appear to point to a company you recognize, but it actually leads to a spoofed domain controlled by the attacker. These sites are often convincing replicas of real login pages, built to steal your credentials or trick you into downloading malware.
This technique is common in phishing campaigns and can lead to serious consequences, including account compromise, data theft, or fraud. It also causes damage to the impersonated brand, especially when the domain is used in widespread credential harvesting or malware delivery.
