first advisory, released February 3, was a response to a dramatic increase in network monitoring by intruders, who were capturing passwords and installing "back doors" for future access to systems
attacks increased in a single week from a few isolated reports to indications that tens of thousands of systems may have been compromised
Unlike most security incidents, this one received extensive attention from the media
the CERT team notified an archive site that their software being readied for distribution had been modified
