I suppose many of you more tech-savvy than I am (which would probably include about 98% of you) already know about the Heartbleed encrypting bug. I’ve read a lot of conflicting information about whether to change your passwords in order to protect yourself, but this article seems to offer the best and most current advice, as of today.
It lists websites that have patched the bug already, and strongly suggests you change your passwords for those sites. Yahoo, for example, is one. Then it lists websites that never were vulnerable in the first place, such as Paypal.
I know people who refuse to do any sort of business online, but most of us have been lulled into it by the convenience of the whole thing. Plus, since so many businesses use computers themselves, I think people feel vulnerable (and perhaps rightly so) no matter what method they use to transact their affairs. The days of cash under the mattress and over the counter still exist, but for most of us they are long gone. We leave a trail wherever we go, not just on computers but on telephones and cameras, at tollbooths and with credit cards. The internet is just one aspect of that.
