1. A computer-implemented method for preventing potential phishing attacks by translating double-byte character set domain name system records, at least a portion of the method being performed by one or more computing devices comprising at least one processor, the method comprising:
extracting, by the one or more computing devices, a domain extension from a double-byte character set (DBCS) domain name in a universal resource locator (URL);
identifying, by the one or more computing devices, a locale code associated with a language utilized on the one or more computing devices;
determining, by the one or more computing devices, if the domain extension matches the locale code;
translating, by the one or more computing devices, the DBCS domain name to a corresponding single byte character set (SBCS) domain name system (DNS) record when the domain extension matches the locale code; and
performing, by the one or more computing devices, a security action that protects against a potential phishing attack based on the translated DBCS domain name.
