13. A non-transitory computer-readable storage medium, bearing computer-readable instructions that, upon execution by a computing node, cause the computing node to perform operations comprising: rendering a domain name as a plurality of images, the domain name being rendered with a different font in each image of the plurality of images; performing optical character recognition (OCR) on the plurality of images to extract text from at least one of the plurality of images, wherein the OCR is configured to resolve different and visually similar characters to a same character; and determining to allow or raise an alert regarding performing an operation on the domain name based at least in part on whether the extracted text from at least one of the plurality of images is found in a set of domain names for which confusingly similar domain names are checked against.
