No, we don’t have guests, these shoes are mine

… is my default answer when new friends come to visit my home and are astonished by my shoe parade. Yes, I’m a shoe addict. I haven’t dared to count my collection, but I must own more than 60 pairs. My shoe cabinets are packed and you will find all colors, brands and styles: high-heels, pumps, sneakers, boots, tip-toes, sandals, trainers, clogs – you name it, I have it. I own 8 pairs alone of classic Chucks of different heights and colors. You may be questioning if this many pairs are really necessary? Oh yes, they are. There is a very particular use for every pair of shoes.

A passion for shoes can easily ruin your Saturday if you are hunting for a certain pair which you just cannot find in the right size in the shoe shops nearby. And no doubt, the habit can get somewhat expensive. Thank goodness the Internet has become a global shopping mall that is open 24/7 so I can not only save time and my best friend’s nerves, but also get occasional good bargains.

But sometimes shopping for shoes online isn’t much fun. Just recently a batch of poisoned links ruined my shoe shopping experience. I was hunting a pair of black ZU heels and was searching the net for the best price. I typed a search term in Google. The third search result sounded promising and so I clicked on the URL. But I didn’t see any shoes, instead I got a warning:

Hey, this was my internet security in action. Well done! But I still wanted a pair of shoes. So I tried the next link and the same thing happened. I clicked the next link – again a warning. The top search results on the first page were poisoned with some malicious code. Very annoying! No shoes for me that day.

Booby-trapped websites are on the rise and what’s even worse, cyber criminals are successfully fooling users with fake anti-virus software and making them pay for useless applications. Google announced a couple of days ago that they had performed a 13 month analysis of 240 million Web pages and fake anti-virus accounted for 15 percent of the malicious software detected. There wouldn’t be as much of it if this wasn’t a lucrative business for criminals.

So be on the lookout when you go shopping online and are searching for popular items. Here are my personal tips for avoiding bad online (shoe) shopping:

  1. Switch search engines once in a while. Google is the most popular and that’s why the criminals target its search results the most.
  2. Check if your internet security solution protects against malware spread through URLs. In F-Secure Internet Security 2010 this feature is called Browsing Protection. If you don’t know what the feature is called in your internet security product, check the vendors website or ask support.
  3. If you’re not using our software or your solution doesn’t offer a URL check, you can use our Browsing Protection for free at http://browsingprotection.f-secure.com/swp/. Just type in the URL you are worried about and the tool tells you if that site is safe or not.
  4. Think before you buy. No security vendor would use a malware warning for marketing and no ticket service on this planet will sell you cheap tickets for the UEFA Champions League Final 2010 in Madrid.

Do you have shopping tips? Do you know some safety checked shopping sites you would like to share? Just drop us a comment below.

Have a great weekend and happy vappu (May 1st) to all our Finnish readers!

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

10 ways to keep your credit card and memories safe during the holidays

Every year Cyber Monday sets new sales records. The Monday after the U.S.'s biggest brick-and-mortar shopping day a year opens the online shopping season with a flood of sales and deals that are often better than what you'll find in person, without the crowds. But whether you're shopping for presents or not during the next month, advertisers and online criminals will assume you are. And if they aren't targeting your wallet, they may be after the private photos and videos we all keep on the hard drives of our computers or devices. Right now, you can get our F-Secure SAFE protection on 5 PCs or devices with 200 GB of free secure cloud storage. Until December 6, we're giving away one free license for SAFE on 5 devices along with 200 GB of storage and a SAFE hoodie for free each day on our Facebook page. Read the the rules and enter now. And while you're shopping on any device, stay skeptical. Stay focused. And keep up the same online shopping and storage hygiene you should be practicing all year long: 1. Make sure your system, browser and security software are patched and protected. If it's software, it requires updates. As developers have become better at reminding you to update your software, there's become more to update. So keep up with your operating system updates and make sure you're running updated security software. 2. Do all your shopping in in one browser. No Java. Our Security Advisor Sean Sullivan advises that you do all of your financial transactions in one browser that you only use for shopping and banking. “Too many tabs open, too many things going on – that’s when you’re most prone to click on a malicious link or download something you shouldn’t have," he said. So use Chrome for surfing and Firefox for the serious stuff. Whichever browser you use for your transactions, you should disable Java in it -- and all your browsers if possible. If a certain website you need to use requires Java, enable it in just one browser that you use only for that site. 3. Stick to stores/sites you trust. Bad grammar and poor design have been the warning signs of malicious sites and emails for years. But criminals are always upping their game. Your best bet is to avoid untrustworthy sites in general, just as you likely avoid unprofessional looking stores and people who randomly try to sell you stereo equipment from their van. Avoid shopping via Google. Go directly to sites you trust and search there. 4. Only shop over a secure connection -- VPN and https. If you're shopping via Wi-Fi, make sure you're on a network you trust or secure yourself with a virtual private network like F-Secure Freedome. This will encrypt your data to protect your passwords and other private data. Freedome also protects you from scams and trackers, which may use your data to sell you things that do not fit your budget. To make sure your data is secure as it's being transmitted, don't enter your private data unless you see you're on a secured connection where the url starts with "https". If you're not seeing that, move on to the next store. 5. Use one credit card for all your online shopping -- or use credit card alternatives. Limit your damages. If your data is captured by a crook, chances are your credit card company will catch any irregularities. However, you still may be left without a card during the holiday season. Using only one card for online purchases also makes it simpler to keep focused on how much you're spending. For extra security, Sean recommends that you see if your bank offers virtual credit card numbers that can only be used once. 6. Check your statements. You do this? Right? If you don't check your statements to make sure all the charges are yours, who will? 7. Do not reuse passwords. It's like putting the same lock on your house, car, boat and safe. Your passwords for your crucial accounts are sacred and need to be unique and strong. This isn't easy, which is why we recommend a password manager. You can use our F-Secure KEY on one device for free. 8. Have a secret email account for online shopping. Sites like Amazon allowing you to use your email for a login, which is convenient. It also means anyone who knows your email, knows your login and is halfway to cracking your account. A simple solution is to use a special email account that you with with no one that you use as login for financial accounts. 9. Back up everything. What's on our devices and PCs is worth more than the hardware themselves because they represent the thing we can never get back -- time. During the holiday season, your phone is filled with memories of celebrations and gatherings that will only happen in that exact way once. So make sure all your devices are backed up, all the time. 10. Use a cloud service you can trust. As you know from the series of nude photos of celebrities released this year, the security of your cloud storage matters. The more people you have trying to hack you, the more your content is at risk. Using a service -- like our younited -- that offers two-factor authentication and is designed to protect your privacy.

What is a supercookie and why is it more important than you think?

Many techie terms in the headlines lately. Supercookies, supertrackers, HTTP headers and X-UIDH. If you just skim the news you will learn that this is some kind of new threat against our privacy. But what is it really? Let’s dig a bit deeper. We will discover that this is an issue of surprisingly big importance. Cookies are already familiar to most of us. These are small pieces of information that a web server can ask our browser to store. They are very useful for identifying users and managing sessions. They are designed with security and privacy in mind, and users can control how these cookies are used. In short, they are essential, they can be a privacy problem but we have tools to manage that threat. What’s said above is good for us ordinary folks, but not so good for advertisers. Users get more and more privacy-aware and execute their ability to opt out from too excessive tracking. The mobile device revolution has also changed the game. More and more of our Internet access is done through apps instead of the browser. This is like using a separate “browser” for all the services we use, and this makes it a lot harder to get an overall picture of our surfing habits. And that’s exactly what advertisers want, advertising is like a lottery with bad odds unless they know who’s watching the ad. A new generation of supercookies (* were developed to fight this trend. It is a piece of information that is inserted in your web traffic by your broadband provider. Its purpose is to identify the user from whom the traffic comes. And to generate revenue for the broadband provider by selling information about who you really are to the advertisers. These supercookies are typically used on mobile broadband connections where the subscription is personal, meaning that all traffic on it comes from a single person. So why are supercookies bad? They are inserted in the traffic without your consent and you have no way to opt out. They are not visible at all on your device so there is no way to control them by using browser settings or special tools. They are designed to support advertisers and generate revenue for the mobile broadband provider. Your need for privacy has not been a design goal. They are not domain-specific like ordinary cookies. They are broadcasted to any site you communicate with. They were designed to remain secret. They are hidden in an obscure part of the header information that very few web administrators need to touch. There are two ways to pay for Internet services, with money or by letting someone profile you for marketing purposes. This system combines both. You are utilized for marketing profit by someone you pay money to. But what can and should I do as an ordinary user? Despite the name, this kind of supercookies are technically totally different from ordinary cookies. The privacy challenges related with ordinary cookies are still there and need to be managed. Supercookies have not replaced them. Whatever you do to manage ordinary cookies, keep doing it. Supercookies are only used by some mobile broadband providers. Verizon and AT&T have been most in the headlines, but at least AT&T seems to be ramping down as a result of the bad press. Some other operators are affected as well. If you use a device with a mobile broadband connection, you can test if your provider inserts them. Go to this page while connected over the device’s own data connection, not WiFi. Check what comes after “Broadcast UID:”. This field should be empty. If not, then your broadband provider uses supercookies. Changing provider is one way to get rid of them. Another way is to use a VPN-service. This will encapsulate all your traffic in an encrypted connection, which is impossible to tamper with. We happen to have a great offering for you, F-secure Freedome. Needless to say, using Freedome on your mobile device is a good idea even if you are not affected by these supercookies. Check the site for more details. Last but not least. Even if you’re unaffected, as most of you probably are, this is a great reminder of how important net neutrality is. It means that any carrier that deliver your network traffic should do that only, and not manipulate it for their own profit. This kind of tampering is one evil trick, throttling to extort money from other businesses is another. We take neutrality and equal handling for granted on many other common resources in our society. The road network, the postal service, delivery of electricity, etc. Internet is already a backbone in society and will grow even more important in the future. Maintaining neutrality and fair rules in this network is of paramount importance for our future society.   Safe surfing, Micke   PS. The bad press has already made AT&T drop the supercookies, which is great. All others involved mobile broadband providers may have done the same by the time you are reading this. But this is still an excellent example of why net neutrality is important and need to be guaranteed by legislation.     (* This article uses the simplified term supercookie for the X-UIDH -based tracker values used by Verizon, AT&T and others in November 2014. Supercookie may in other contexts refer to other types of cookie-like objects. The common factor is that a supercookie is more persistent and harder to get rid of than an ordinary cookie.   Image by Jer Thorp
