Facebook Security Tip: Check to See Who Is Using Your Facebook Account
Facebook Security Tip: Check to See Who Is Using Your Facebook Account
February 1, 2011 By Harrison Painter
While it is my belief that there is no true privacy when using facebook, security is a much different issue that users need to be aware of. If you have ever been a target of suspicious behavior, and believe someone might have been using your account without your knowledge, please know that there is an “Account Security” area built into Facebook. Here you can check what devices have logged into your account by date, approximate location based on IP address, and device used.
To access these settings, log into Facebook –> Account –> Account Settings –> Account Security.
As you can see in the image below, you can check the box to have an email sent to you anytime a new computer or mobile device logs into your account. I highly recommend you check this box and click save.
You will also see your most recent activity as I described above. If you notice any odd locations or devices that might have had access, you can click the words “end activity” on the right hand side and stop the use.

Hours spent on Twitter? Don’t click on scam spreading virally on Twitter
by Graham Cluley on May 8, 2011

Another rogue application is spreading between unsuspecting Twitter users, claiming to tell you how many hours you have spent on on the network.
The messages all look pretty similar, and use a currently trending topic such as Richard Dawkins, Cheryl Cole landing the job of a judge on the US edition of “X Factor”, or it being Mother’s Day in the United States.
Richard Dawkins –> I have spent: 23.8 hours on Twitter! See how much you have: [LINK]
#zabecca –> I have spent: 20.9 hours on Twitter! See how much you have: [LINK]
Vidal Sassoon –> I have spent: 33.4 hours on Twitter! See how much you have: [LINK]
#5factsaboutmymom –> I have spent: 33.4 hours on Twitter! See how much you have: [LINK]
Even though you may have seen one of your friends tweet out a message like this, you definitely shouldn’t click on the link. It will take you to a rogue third-party application which asks your permission to connect with your Twitter profile.
If you do authorise the app it will be able to post messages to Twitter in your name, see who you follow on Twitter, grab your Twitter name and avatar, and update your profile. Now, why on earth would you want to give a complete stranger the ability to do that?
Unfortunately, you may be so desperate to find out how many hours they have spent on Twitter (after all, your friends appear to have already been though the process) that you will authorise the application.
Whereupon, the rogue application will tweet the offending message from your Twitter account. When I went through the process on a test Twitter account I run, I found that it tweeted out the message more than a dozen times in less than 30 seconds.
You may not realise that this is happening, however, as the app is distracting you with a message saying it is processing your results. After some whirring away, it asks you to enter your email address to have your results sent to you.
Stop right there! (if you haven’t already). Are you seriously going to give these complete strangers access to your email address too? They already know your Twitter account name, and can post to your Twitter page – now they’ll be able to email you as well!
Who knows what they might send you? Their plan might be to send you spam, a Trojan horse, or a phishing attack. They even have the cheek to say watch out for the message in your spam folder!
I don’t know what the scammers plan to spam out to you, and it could – of course – be weeks or months before they do, but if you want to find out more follow me on Twitter at @gcluley.
These sorts of rogue applications appear to be popping up more and more on Twitter, whereas previously they were mostly seen only by Facebook users.
If you were unfortunate enough to grant a rogue applications access to your Twitter account, revoke its rights immediately by going to the Twitter website and visiting Settings/Connections and revoking the offending app’s rights.
Don’t make it easy for scammers to make money in this way, and always exercise caution about which third party apps you allow to connect with your social networking accounts.
If you’re on Twitter and want to learn more about threats, be sure to follow Naked Security’s team of writers.

Skype security flaw already patched, but you have to download manually
There’s a big problem with Skype on the Mac: and no, it’s not its ugly UI (although that is a big problem). As noted by Mashable’s (and former TUAW blogger) Christina Warren, the latest version of Skype for Mac has an unpatched security flaw that that allows a person to gain remote access to another’s machine simply by sending a Skype message. The flaw was discovered last month thanks to the work of researcher Gordon Maddern from the firm Pure Hacking. Maddern contacted Skype, who was reportedly already aware of the vulnerability and working on a fix. They then issued a hotfix for the security hole in a minor update (Skype for Mac version 5.1.0.922) on April 14th. However, responding to the issue in an official blog post today the Skype for Mac team said, “As there were no reports of this vulnerability being exploited in the wild, we did not prompt our users to install this update, as there is another update in the pipeline that will be sent out early next week.” What’s that mean to you as a Skype for Mac user? The cat’s out of the bag, and if someone who has the skills to take advantage of the flaw now knows about it, Skype for Mac users who have not updated to version 5.1.0.922 are theoretically at risk. Don’t wait for the automatic update to Skype next week. Be sure and download the April 14th update right now by clicking here, or simply run Skype on your Mac and choose Skype > Check for Updates.
Now about that UI…
