The exposure of old, embarrassing posts by MSNBC columnist Joy Ann Reid has provoked a lot of heated discussion. It’s also revealed the difficulty of retaining reliable information about old material on the Web.
When these old posts came to public attention through Twitter, she asserted that there had been one or more unauthorized break-ins altering her articles to add offensive content.
In December I learned that an unknown, external party accessed and manipulated material from my now-defunct blog, The Reid Report, to include offensive and hateful references that are fabricated and run counter to my personal beliefs and ideology.
I began working with a cyber-security expert who first identified the unauthorized activity, and we notified federal law enforcement officials of the breach.

The article starts with a fair warning that the vulnerability is “so simple you’ll need to put a cushion on your desk before you read any further (in case of involuntary headdesk injury).” It explains that because of the coding mistake called “Zip Slip,” “attackers can create Zip archives that use path traversal to overwrite important files on affected systems, either destroying them or replacing them with malicious alternatives.” This is where I started to suspect.
The vulnerability isn’t in the Zip format as such, but in bad coding found in some of the zillion ad hoc pieces of software written to unpack Zip files. Have you figured it out yet? I’ll put the cut here to give you a chance to think…
