10 Internet security tips that John would never follow

First of all, if you haven’t done it yet, please take this quick quiz to find out if you’re smarter than the guy in the video below. (After you complete the quiz, you can enter to win an Xbox 360 and a Kinect.)

Now that took the quiz know how much smarter you are than John, here’s a quick review of why you shouldn’t do anything John does online.

1. Use unique, strong passwords for all of your important accounts.
John uses the same password for every account. That means if a hacker gets a hold of John’s Twitter password, that hacker would have access to every account John uses at work or at home. Creating and remembering unique, strong passwords is a must for your most important accounts. This system for creating and remembering strong passwords makes it easy.

2. Keep your computer’s software patched and protected.
You probably know which operating system you’re running. John doesn’t. He thinks it’s the one with the “windows.” A PC or a Mac running the latest versions of Windows 7 or OS X is probably as safe as any PC since the birth of the virus. However, if your OS and your applications aren’t patched you may be vulnerable to the kind of attacks John has to deal with on a daily if not hourly basis. Checking all of your applications for updates on a regular basis can be time-consuming. Our free Health Check makes it easy.

3. Realize that you’re vulnerable when you’re on an open Wi-Fi network.
When you use an open Wi-Fi network, the data you enter is only encrypted on secure pages, which start with https. Banks and credit card companies encrypt their sites however not all web email is encrypted. If you’ve ever emailed passwords or personal information, it could be accessible to a hacker. On an unsecured Wi-Fi network, you could get sidejacked by someone using a tool like Firesheep. Using the tracking data in your browser, a hacker can easily pretend she or he is you.

If you have to check your email or get on a social network and you only have open Wi-Fi, make sure you are using a secured session.

How to Secure Sessions

VPN
A virtual personal network is the best way to defend yourself from any snoopers. Most large companies insist on their employees using a VPN while doing any business over a wireless network. That’s a strategy John would never follow, but you should, especially if you make purchases or work with confidential information while on public Wi-Fi. Here are some strong VPN options for you to consider.

HTTPS Everywhere

If you use Firefox, you can use HTTPS Everywhere by The Tor Project and the Electronic Frontier Foundation, which will encrypt your communications on several major websites.

Twitter
You can secure any Twitter session by typing in an “s” after the http in the browser bar. If you click here, you’ll go to https://twitter.com and session will remain secure until you log out.

Facebook
This feature is still being rolled out to some users. And it is not entirely secure.

You can activate secured browsing by logging in. Then go to Account> Account Settings> Under “Account Security”, check the box for “Browse Facebook on a secure connection (https) whenever possible”.

PLEASE NOTE: If you use an app, any Facebook app, you’ll get this warning:

PLEASE NOTE: If you use an app, any Facebook app, you’ll get a warning that you are now entering unsecured browsing.

If you continue on to unsecured browsing, your session is not unsecured and you are now vulnerable to a sidejacking attack. You will have to return to the same setting when you are done with the app to enable secured browsing again.

John was recently sidejacked by a friend who posted a hilarious Photoshop of John in the bathtub. Too bad it happened on a day when the HR department of a company that was about to hire John checked out his profile.

Gmail
Login and go to the “Options” wheel in the uppermost right corner.

Select “Mail settings”.

Under “Browser connection”, select “Always use https”.

Hotmail

Go to https://account.live.com/ManageSSL and login if you have to.

Select “Use HTTPS automatically (please see the note above)”. And check out the note for the exceptions, of course.

4. Check to make sure a site is legitimate and secure before you make a purchase.
John will buy anything from any site. He bought his Snuggie from a website that had more pop-ups than the old AOL. Don’t be like John. Stick to online stores with good reputations. When you try out a new retailer, do a quick search for customer feedback. If you are still unsure, save yourself the trouble and money. Even if you trust a site, always check the URL of the page for two things before submitting your credit card number: 1) Is it a secured https page that will encrypt your information? 2) Am I really on the site I meant to be on? Try to use one credit card for all your online shopping and check the activity on that account often. Check out these safe shopping tips.

5. Don’t be afraid to reject or ignore a Facebook friend request.
On Facebook, wrong click and you could end up spamming your friends with something that will definitely waste their time and possibly your money. The best way to avoid becoming a victim or perpetrator of spam is to eliminate spam from your news feed. This requires you only friending people who are careful where they click. John, of course, lets spammers go on spamming as he adds more and more friends. You, however, should be careful who you add. If a friend shares some spam, inform them in a friendly way that they may have made a mistake. If it keeps happening, unfriend her or him.

Something else to remember: If you wouldn’t tell someone in person that you’re going to be out of town, don’t use Facebook to do so. If your Privacy Settings are set to “Friends of Friends”, you could be sharing your travel plans with thousands of people when you post them on Facebook. Before you post anything, ask yourself, “Would I be okay if all the friends of my friends’ friends knew this?” If your friends are anything like the average Facebook user, you could be thinking about more than a million people. (The average Facebook user has 120 friends. 120 X 120 X 120 = 1,728,000 friends you could be sharing with.)

6. Never use a password that is in the dictionary or could be guessed by a friend.
We’re back to passwords again because they can tend to be a weak link in many users’ security. And this weak link can be easily strengthened. The number of people who use “password” or their first name to secure their accounts is mind-blowing. Even John wouldn’t be that silly. It’s just as silly to use any word in the dictionary. Why? Because when a hacker uses a program to figure out your password, what do you think it tries first? Your passwords have to be unique and complex. They should also not be anything that could be guessed by a friend. If someone you know can guess your password, a stranger might be able to do the same thing by studying your Facebook profile.

7. Keep an eye out for Phishing Scams, even when you’re on your phone.
A Phishing Scam is a sneaky attempt to get you to turn over your financial data to criminals. That’s right crooks have found that Internet users, like John, will occasionally just hand over the account information needed to commit credit card fraud. All they do have to do is pretend to be a trustworthy site with official looking graphics and people fill in the forms and click submit. The best way to avoid Phishing scams is to check the URL of the webpage you are on to make certain it is on the domain of the bank or institution you think it is. Also, be skeptical of any email that contacts you asking you to change your password. If you’re ever in doubt, contact the institution directly. All of your accounts have values to a scammer, so keep in mind that you can even be phished for your Facebook account—and even when you’re on your phone. That’s why our Mobile Security blocks such scams.

8. Password protect your Wi-Fi network.
There’s plenty of good reasons to secure your home Wi-Fi network. You don’t want your neighbors to have access to private info. You don’t want strangers to slow down the connection you’re paying for. You don’t want people to use your connection to take part in illegal activities. The only reason to leave it open is if you want to give someone like John access to your digital life. Here’s how to set up a security key for your wireless network.

9. Don’t open strange email attachments (without scanning them).
The first computer security rule you probably learned was “Don’t open email attachments from strangers.” This is still true—even though John forgot it long ago. In fact, targeted attacks that use social engineering and profile their victims are becoming more advanced all the time. You should still refuse to open any attachment that you were not expecting. If you feel you must open an attachment, download it to you PC and scan it with your Internet security software first.  Here’s more on how to deal with email attachments.

10. Don’t expect anyone else to protect your privacy.
Do you blame your telephone when you use it to tell someone something you shouldn’t? Then you can’t only blame Facebook when you post information that may cause you trouble. Even when you use the privacy settings correctly and keep your account under control, your information is only as secure as the people you share it with. If you need to share any information that could cause you trouble at work or could be used to answer your security questions, use private messages, email or even that old-fashion marvel the telephone. And never, under any circumstances, shout your password in public through a megaphone. John still hasn’t learned that one yet.

Which of these tips is most important? Which is John least likely to follow? Let us know in the comments.

Cheers,

Sandra

DoS

What is a DoS attack really?

Ordinary people here in Finland have been confronted with yet another cybersecurity acronym lately, DoS. And this does not mean that retro-minded people are converting back to the pre-Windows operating system MS-DOS that we used in the eighties. Today DoS stands for Denial of Service. This case started on New Year’s Eve when customers of the OP-Pohjola bank experienced problems withdrawing cash from ATMs and accessing the on-line bank. The problems have now continued with varying severity for almost a week. What happens behind the scene is that someone is controlling a large number of computers. All these computers are instructed to bombard the target system with network traffic. This creates an overload situation that prevents ordinary customers from accessing the system. It’s like a massive cyber traffic jam. The involved computers are probably ordinary home computes infected with malware. Modern malware is versatile and can be used for varying purposes, like stealing your credit card number or participating in DoS-attacks like this. But what does this mean for me, the ordinary computer user? First, you are not at risk even if a system you use is the victim of a DoS-attack. The attack cannot harm your computer even if you try to access the system during the attack. Your data in the target system is usually safe too. The attack prevents people from accessing the system but the attackers don’t get access to data in the system. So inability to use the system is really the only harm for you. Well, that’s almost true. What if your computer is infected and participates in the attack? That would use your computer resources and slow down your Internet connection, not to speak about all the other dangers of having malware on your system. Keeping the device clean is a combination of common sense when surfing and opening attachments, and having a decent protection program installed. So you can participate in fighting DoS-attacks by caring for your own cyber security. But why? Who’s behind attacks like this and what’s the motive? Kids having fun and criminals extorting companies for money are probably the most common motives right now. Sometimes DoS-victims also accuse their competitors for the attack. But cases like this does always raise interesting questions about how vulnerable our cyber society is. There has been a lot of talk about cyber war. Cyber espionage is already reality, but cyber war is still sci-fi. This kind of DoS-attack does however give us a glimpse of what future cyber war might look like. We haven’t really seen any nations trying to knock out another county’s networks. But when it happens, it will probably look like this in greater scale. Computer-based services will be unavailable and even radio, TV, electricity and other critical services could be affected. So a short attack on a single bank is more like an annoyance for the customers. But a prolonged attack would already create sever problems, both for the target company and its customers. Not to talk about nation-wide attacks. Cyber war might be sci-fi today, but it is a future threat that need to be taken seriously.   Safe surfing, Micke   Image by Andreas Kaltenbrunner.

Help! I lost my wallet, phone and everything! I need 1000 €!

“Sorry for the inconvenience, I'm in Limassol, Cyprus. I am here for a week and I just lost my bag containing all my important items, phone and money at the bus station. I need some help from you. Thanks” Many of you have seen these messages and some of you already know what the name of the game is. Yes, it’s another type of Internet scam, an imposter scam variant. I got this message last week from a photo club acquaintance. Or to be precise, the message was in bad Swedish from Google translate. Here’s what happened. First I got the mail. Needless to say, I never suspected that he was in trouble in Limassol. Instead I called him to check if he was aware of the scam. He was, I wasn’t the first to react. Several others had contacted him before me and some were posting warnings to his friends on Facebook. These scams start by someone breaking in to the victim’s web mail, which was Gmail in this case. This can happen because of a bad password, a phishing attack, malware in the computer or a breach in some other system. Then the scammer checks the settings and correspondence to find out what language the victim is using. The next step is to send a message like the above to all the victim’s contacts. The victim had reacted correctly and changed the Gmail password ASAP. But I wanted to verify and replied to the scam mail anyway, asking what I can do to help. One hour later I got this: “Thanks, I need to borrow about 1000 euros, will pay you back as soon as I get home. Western Union Money Transfer is the fastest option to wire funds to me. All you need to do is find the nearest Western Union shop and the money will be sent in minutes. See details needed WU transfer below. Name: (Redacted) Address: Limassol, Cyprus you must email me the reference number provided on the payment slip as soon as you make the transfer so I can receive money here. Thank you,” Now it should be obvious for everyone how this kind of scam works. Once the scammers get the reference number they just go to Western Union to cash in. Most recipients will not fall for this, but the scammers will get a nice profit if even one or two contacts send money. But wait. To pull this off, the scammers need to retain control over the mail account. They need to send the second mail and receive the reference number. How can this work if the victim had changed his password? This works by utilizing human’s inability to notice tiny details. The scammers will register a new mail account with an address that is almost identical to the victim’s. The first mail comes from the victim’s account, but directs replies to the new account. So the conversation can continue with the new account that people believe belongs to the victim. The new address may have a misspelled name or use a different separator between the first and last names. Or be in a different domain that is almost the same as the real one. The two addresses are totally different for computers, but a human need to pay close attention to notice the difference. How many of you would notice if a mail address changes from say Bill.Gates@gmail.com to BiII_Gates@mail.com? (How many differences do you notice, right answer at the end?) To be honest, I was sloppy too in this case and didn’t at first see the tiny difference. In theory it is also possible that webmail servers may leave active sessions open and let the scammers keep using the hacked account for a while after the password has been changed. I just tested this on Gmail. They close old sessions automatically pretty quickly, but it is anyway a good idea to use the security settings and manually terminate any connection the scammers may have open. I exchanged a couple of mails with this person the day after. He told that the scammers had changed the webmail user interface to Arabic, which probably is a hint about where they are from. I was just about to press send when I remembered to check the mail address. Bummer, the scammer’s address was still there so my reply would not have reached him unless I had typed the address manually. The account’s reply-to was still set to the scammer’s fake account. OK, let’s collect a checklist that helps identifying these scams. If someone asks for urgent help by mail, assume it’s a scam. These scams are a far more common than real requests for help. We are of course all ready to help friends, but are YOU really the one that the victim would contact in this situation? Are you close enough? How likely is it that you are close enough, but still had no clue he was travelling in Cyprus? Creating urgency is a very basic tool for scammers. Something must be done NOW so that people haven't got time to think or talk to others. The scammers may or may not be able to write correct English, but other languages are most likely hilarious Google-translations. Bad grammar is a strong warning sign. Requesting money using Western Union is another red flag. Wire transfer of money provides pretty much zero security for the sender, and scammers like that. Many scammers in this category try to fake an embarrassing situation and ask the recipient to not tell anyone else, to reduce the risk that someone else sees through it. These messages often state that the phone is lost to prevent the recipient from calling to check. But that is exactly what you should do anyway. Next checklist, how to deal with a situation where your account has been hijacked and used for scams. Act promptly. Change the mail account’s passwords. Check the webmail settings and especially the reply-to address. Correct any changed settings. Check for a function in the web mail that terminates open sessions from other devices. Gmail has a “Secure your account” -wizard under the account’s security settings. It’s a good idea to go through it. Inform your friends. A fast Facebook update may reach them before they see the scammer’s mail and prevent someone from falling for it. It also helps raising awareness. And finally, how to not be a victim in the first place. This is really about account security basics. Make sure you use a decent password. It’s easier to maintain good password habits with a password manager. Activate two-factor authentication on your important accounts. I think anyone’s main mail account is important enough for it. Learn to recognize phishing scams as they are a very common way to break into accounts. Maintain proper malware protection on all your devices. Spyware is a common way to steal account passwords. The last checklist is primarily about protecting your account. But that’s not the full picture. Imagine one of your friends falls for the scam and loses 1000 € when your account is hacked. It is kind of nice that someone cares that much about you, but losing money for it is not nice. Yes, the criminal scammer is naturally the primarily responsible. And yes, people who fall for the scam can to some extent blame themselves. But the one with the hacked account carries a piece of responsibility too. He or she could have avoided the whole incident with the tools described above. Caring about your account security is caring about your friends too! And last but not least. Knowledge is as usual the strongest weapon against scams. They work only as long as there are people who don’t recognize the scam pattern. Help fighting scam by spreading the word!   Safe surfing, Micke   PS. The two mail addresses above have 3 significant differences. 1. The name separator has changed from a dot to an underscore. 2. The domain name is mail.com instead of gmail.com. 3. The two lower case Ls in Bill has been replaced with capital I. Each of these changes is enough to make it a totally separate mail address.   Image by Yumi Kimura

5 ways to get ready to ask Mikko anything

It's like a press conference anyone can join from anywhere. And even if you don't have a question, you can upvote the ones you don't like and downvote the ones you do. President Obama did one. Snoop Dogg/Snoop Lion did one. An astronaut did one from outer space. And our Mikko Hypponen will sit down for his second Reddit AMA on December 2 at 8 AM ET. If you have something you've wanted to ask him about online security, great. If not, here are five resources that document some of Mikko's more than two decades in the security industry to prod you or prepare you. 1. Check out this 2004 profile of his work from Vanity Fair. 2. Watch his 3 talks that have been featured on TED.com.
