Yahoo Confirms It Has Fixed a Vulnerability in Mail

wrenchesWeb giant Yahoo just confirmed that it has been dealing with a vulnerability to its email service that may be connected to a surge in breaches of email accounts that are being used to send spam and other annoying content.

I just got a statement from a Yahoo spokeswoman saying that the vulnerability seen in a video has been fixed. Yahoo hasn’t commented on whether or not the vulnerability is the same one it was notified about on Nov. 12.

Anyway, here’s the statement in full. Change your passwords, folks.

“At Yahoo! we take security very seriously and invest heavily in measures to protect our users and their data. We were recently informed of an online video that demonstrated a vulnerability. We confirm that the vulnerability has been fixed. In addition, we are investigating recent reports of increased abusive traffic and will work diligently to fix any vulnerabilities that are found. Concerned users are encouraged to change their passwords to a safe password that combines letters, numbers, and symbols.”
