Was Yahoo Mail Hacked by Chinese Spammers Over the Weekend?
This morning, a colleague at work reported that someone had broken into his online Yahoo mail account over the weekend and sent a single spam email to all the people in his contact address book. The message advertised a website and asked people to buy the spammer’s goods.
He asked me to help work out how his account had been compromised.
The spam message remained in his sent box, so I examined the full headers. After doing a reverse lookup of the IP address, I found out that it was sent from a host located in China.
After doing a google search, I discovered that at least one other person had their account misused in the same way – as reported in this post on Yahoo answers dated 22nd August.
So far, I have not found any media coverage of any incident, so I am wondering how widespread this problem is. If you or anyone you know has had their Yahoo mail account misused in this way, please make a comment. Also, don’t forget to report this to Yahoo support.
