I just read an article talking about so-called “supercookies” and “evercookies” — cookies which are supposedly impossible to delete, and left without the computer user’s permission or even knowledge. What are “supercookies”? What are “evercookies”? And how can I protect my computer from them?
I’ll start out by saying that options to protect yourself from supercookies and evercookies are relatively limited, if effective at all.
Supercookies and evercookies are the result of a website owner’s desire (or more often, the desire of the advertising networks used by websites) to accumulate data about computer users and the sites they visit — even those users who disable or clear cookies in their browser regularly.
Bottom line: clearing cookies isn’t enough — not nearly enough.
The question assumes, of course, that you know what a cookie is.
It’s a surprisingly simple concept that can be used in a variety of ways, ranging from tracking your behavior across the web to ensuring that you don’t need to log in every time you open even a single email.
And thus we have “tracking” and “third party” cookies to talk about.
I’ve got a quick question concerning saved username/passwords in browsers. Whenever you visit a website and need to login, you’ll be asked (depending on your browser settings) if you’d like to “save” the username/password information to make future logins easier. If you choose to do so, is this username/password information made visible to anyone who has compromised your computer when you access the website in the future? Since the fields are already filled in for you, you don’t actually need to type in anything.
The short answer is yes – if you’re not careful, anyone who walks up to your computer can access those websites as you, or perhaps even walk away with a copy of all your usernames and passwords.
There are actually several important issues around letting your browser – or any utility for that matter – save your passwords. Particularly when we advocate using multiple complex and different passwords for different sites, it’s not only important to use these types of features to keep it all straight, but to use them properly so as not to expose yourself to security issues should your machine ever be compromised.
I’ll review how these features work, and how to use them safely.
I visited a website and two days later, I received marketing information through email from that website for their products. How could they know my email without me providing it when I visited the website? Could it be that they have group mailed somehow? The mail came on my Gmail account.
Depending on the site, it could be a coincidence. Many large companies use mass market email and the fact that you received a message might be completely random.
There are several ways that a company could do this… and again, it’s not based on paranoia. You just need to understand what technology these companies have that allows them to do this.
It all boils down to related sites or sites that use related advertising.
I’m using Windows 7 and I want to keep my two Yahoo email addresses open just like on my cell phone. But when I sign into the second Yahoo email, it signs me out of the first. Ideally, I want both to be open when I turn on the computer so I can view both at any time.
Surprisingly, this is a common desire. Many people have more than one email address these days. You can use a couple of approaches to do this.
Hi, Leo. I believe that every time I run CCleaner, my bank doesn’t recognize me anymore. I then have to go through a whole rigmarole to get on to my account. It’s been suggested that the cause is that I’ve erased the cookie that my bank site has planted and therefore it doesn’t recognize my PC anymore. I use Firefox on XP. Do you agree? How can I identify its cookies so that I can isolate it so that CCleaner will not erase it. If you don’t agree then, what do you think is the problem?
