It’s only been a week since I was prompted by Google to change my Google accounts password yet just today I was faced again with a similar predicament on e-mail account security with Yahoo! Mail.
Two weeks ago I discovered in my Sent Folder that more than 10 of my GMail contacts had received an e-mail which was purportedly sent from my main GMail account containing a spam link. Last Saturday my Yahoo! Mail inbox was littered with around 10 Unsent Mail notifications to unknown contacts. I looked in my Sent Mail folder and sure enough my e-mail address was sending spam links to e-mail addresses.
I logged in my Yahoo! Mail account from my sister’s laptop an hour ago to change my password because from the Mail app on my iPhone, I could not access my Yahoo! Mail since Sunday. The account verification on Yahoo! was brief and in a few minutes I was able to log in back to my main Yahoo! Mail account. I feared if I had not taken action sooner I would have missed important e-mails.
I believe these incidents of spam links messing up our passwords are coming mostly from third-party application sign-ins. Some online sites or mobile applications do require us to log in via Facebook, Twitter or Google. I have observed that the e-mail accounts affected were two main accounts I use mainly for logging into third-party applications.
