Common Attack Pattern Enumeration and Classification
A Community Resource for Identifying and Understanding Attacks
An adversary registers a domain name that sounds the same as a trusted domain, but has a different spelling. A SoundSquatting attack takes advantage of a user's confusion of the two words to direct Internet traffic to adversary-controlled destinations. SoundSquatting does not require an attack against the trusted domain or complicated reverse engineering.
An adversary sends an email, impersonating the popular banking website guaranteebanking.com, to a user stating that they have just received a new deposit and to click the given link to confirm the deposit.
However, the link the in email is guarantybanking.com instead of guaranteebanking.com, which the user clicks without fully reading the link.
The user is directed to the adversary's website, which appears as if it is the legitimate guaranteebanking.com login page.
The user thinks they are logging into their account, but have actually just given their guaranteebanking.com credentials to the adversary. The adversary can now use the user's legitimate guaranteebanking.com credentials to log into the user's account and steal any money which may be in the account.
SoundSquatting vulnerability allows an adversary to impersonate a trusted domain and leverages a user's confusion between the meaning of two words which are pronounced the same into visiting the malicious website to steal user credentials.
Skill or Knowledge Level: Low
Adversaries must be able to register DNS hostnames/URL’s.
Authenticate all servers and perform redundant checks when using DNS hostnames.
Purchase potential SoundSquatted domains and forward to legitimate domain.
