Abstract:
1. A method, comprising: receiving an electronic mail message at a client computing device that includes a processor and a memory; parsing an object included in the electronic mail message to allow strings of symbols across lines of the object to be identified; determining a ratio of symbols in a portion of the object to a total number of characters in the portion of the object; comparing the ratio to a predetermined threshold to determine whether the object should be decoded; decoding characters of the object based on a font size and associations of formation characters to determine decoded characters that extend across sequential lines of the object, wherein for a particular font and the font size, the strings of symbols are identified as formation characters based on corresponding width and line values associated with consecutive spaces in sequential lines; comparing the decoded characters to known unwanted content; and calculating a score associated with the object based on a predefined weight for decoded characters that match the known unwanted content.
