The fourth paragraph of the story, "Yahoo Messenger flaw enables spamming through other people's status messages," contained a quote in which a source incorrectly described how a Yahoo Messenger flaw is exploited.

"An attacker can write a script in less than 50 lines of code to malform the message sent via the YIM protocol to the victim," said Bogdan Botezatu, an e-threats analysis & communication specialist at BitDefender.
