CAPEC-632: Homograph Attack via Homoglyphs
MITRE CAPEC attack pattern
| Status | Draft |
| Typical severity | Medium |
| Likelihood of attack | Low |
| Catalogue | CAPEC 3.9 (2023-01-24) |
Description
An adversary registers a domain name containing a homoglyph, leading the registered domain to appear the same as a trusted domain. A homograph attack leverages the fact that different characters among various character sets look the same to the user. Homograph attacks must generally be combined with other attacks, such as phishing attacks, in order to direct Internet traffic to the adversary-controlled destinations.
Where this sits in the chain
A finding maps to a weakness (CWE), a weakness is exploited by an attack pattern (CAPEC), and an attack pattern shows up in ATT&CK as observed adversary behaviour. This page is the middle hop.
Weaknesses exploited: CWE-1007
Prerequisites
- An adversary requires knowledge of popular or high traffic domains, that could be used to deceive potential targets.
Skills required
- Low: Adversaries must be able to register DNS hostnames/URL’s.
Consequences
- Other: Other
Mitigations
- Authenticate all servers and perform redundant checks when using DNS hostnames.
- Utilize browsers that can warn users if URLs contain characters from different character sets.
