NAME

ungoopspam - clarify HTML obfuscations popular with spammers

SYNOPSIS

ungoopspam [file ...]

DESCRIPTION

The ungoopspam utility reads an HTML document from file (or standard input if no files are specified), and performs a number of transformations.

• The document is converted from quoted-printable encoding to plain 8-bit text. This may have happened if the spammer attached the web page using QP format. It's actually a function of the mail system, not HTML.

• Any HTML entities, such as ``"'' or ``A'' are converted to their 8-bit character equivalent.

• Hex encoding (``%nn'') in URIs is converted to its 8-bit character equivalent.

BUGS

This utility is a hack. It is not a rugged tool built for a production environment. It exists to assist you in decoding the obfuscated web pages favored by spammers.

Quoted-printable is recognized by a low-rent heuristic.

The ``%nn'' hex character decoding is performed throughout the document, not just in URIs. This may lead to undesired results.
