Your boss is worried. And her boss is worried, and so is her boss’ boss and so on… They’re all worried about Facebook and what you’re doing there.
More than 50% the largest corporations in America are so worried that they do not allow their employees to visit any social networking sites at work. No Facebook. No Twitter. Not even any LinkedIn! That could get pretty depressing.
Some of their worry is justified – even military officials have been caught posting classified information online. But a complete social networking ban is probably unenforceable, as the US Army has discovered. And in a new survey, we’re finding that over 50% of employees are still using Facebook at work.
Even if employers forbid social networking on company PCs, are they going to monitor what you’re doing on your smart phone?
Banning social media may even lead to a DECREASE in employee productivity. Yes, a DECREASE. Limited social network use has been linked to an overall increase in employees’ concentration and productivity. And companies like Dell have proven than embracing social networking can improve the bottom line.
Now, if your employer bans social networking for security reasons, that makes more sense.
Joan Goodchild of CSO Online lays out some excellent arguments against using Facebook specifically in her article “10 Security Reasons to Quit Facebook (And One Reason to Stay On).” And F-Secure’s Chief Research Officer Mikko Hyppönen refuses to open a Facebook account for security reasons, though he’s a fan of Twitter.
Despite the risks, I believe that shutting employees out from social networks disconnects them from what Ralph Waldo Emerson called “the current of events.” Employers can’t afford to keep employees who aren’t connected to rapidly evolving business climate around them. And employees— in an economy where anything that can be automated will be— shouldn’t neglect the opportunity to develop a unique online identity.
But if you’re going to engage in online communities during work hours, it’s your obligation to be safe and savvy about it. Here are a few specific steps you should take to protect yourself, your employer and your job:
1. Know your company’s social media policy and follow it.
Are you allowed to use social networks on company PCs? How often? Which sites? Should you comment as employee or about company matters? What company information are you allowed to share? Who should you consult if you have a question about any of these issues? All of these questions and more should be answered in your company’s social media policy. If you have never read your company’s policy, do it now. If your company doesn’t have a policy, suggest that they create one. Here are some examples. If the policy isn’t realistic, make a case for a policy that works.
2. Use different passwords for your work and your social media accounts.
Smart passwords matter. Annika has written about the importance of creating and remembering strong passwords. A vulnerable password on your Facebook account can jeopardize your personal reputation and friends. Don’t magnify the risk by using the same password for your corporate network.
3. Always log off when you leave your desk.
It’s smart security to log off your computer when you leave your desk. This is even more important when you have your social networking accounts open. If you leave your desk with your browser open to Facebook, you’re begging for a goofy co-worker to post a ridiculous status update in your name. In fact, it’s good policy to log off any site when you’re not using it. You probably don’t want the reputation of being the guy or gal who is always on Facebook, even when you’re sleeping.
4. Avoid unnecessary risks.
Don’t click on or forward links you are unsure about—check any URL with F-Secure’s free Browsing Protection. If someone is asking you for financial help or to spread the word about some controversy, check it out when you get home. Most importantly, leave installing software to the experts. If you need to install a plug-in to see something linked off a Twitter page, you probably don’t need to see that page.
5. Think about what you share with whom.
You know that you should never post anything on the web that you wouldn’t want to see in a newspaper. Consider anything that you post —including items you limit to only “friends” or “friends of friends”— to potentially be in the public domain. This list of 11 things you should never do online provides some great guidelines about what not to share.
Things that you’re fine with being public now may seem embarrassing or even painful later. You may wish for all those pictures of you and your ex or the videos of you and your former coworkers at karaoke would just disappear. But they won’t. So consider who you add to which accounts. Maybe you just want to use Facebook exclusively for non-work friends. Maybe you only want professional connections on LinkedIn. Whatever you do, think before you accept an invitation to connect. And on a site like Twitter, where your tweets are probably open to everyone, think before you share anything.
How do you use social networks at work? Do you have any rules to add? We’d love to know. Take this quick survey and comment below.
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.
A new Mercedes. Nice. Or maybe an Audi R8? That would be cool. But hold it! Don’t sell your old car yet! Liking and sharing that giveaway campaign on Facebook will NOT give you a new car. Those prizes doesn’t even exist. They are just hoaxes. Internet and Facebook is full of crap, junk, rubbish, nonsense and gibberish. Nobody knows how many chain letters there are spreading some kind of unbelievable story. False celebrity news, bogus first-aid advice, phony charity campaigns and this kind of giveaways. We tend to think about these chain letters as hoaxes, pretty harmless jokes that doesn’t hurt us. But that’s not the full story. A hoax can be harmful, like the outright dangerous first aid advice that some people keep spreading. But a car giveaway is probably a harmless and safe prank, even if it’s false? No, not really. These chain letters are actually not traditional hoaxes, they are like-farming scams. There’s no free lunch, you don’t pay for Facebook with money but with your private data. The like-farming scams work in the same currency. You will not lose any money even if you like the page and share it. Instead you will participate in building a page with a lot of supporters, which is valuable and can be sold later. Needless to say, you will not get any of that money. Here’s how it works. Any business has a problem when starting on Facebook. An empty page without likes isn’t trustworthy. So the scammers set up a page containing anything that can go viral. A promise to get a luxury car works well. They just have to tell everyone to like the page and to share it as much as possible, to keep the chain reaction going and get even more likes. The scammers wait until there’s enough likes before they clean out the content, rename it and start looking for a buyer. The price is in “$ per k”, meaning dollars per 1000 likes. A page with 100 000 likes could sell for over $1000. So sharing the page can make quite a lot of money for the scammers if you have a lot of gullible friends, who in turn have a lot of gullible friends, and so on … The downside for you is that the likes stick even if the page is redesigned for some totally different purpose. Your face will be an evangelist for the page’s new owners and show up next to their brand. And you have no idea about what you will be promoting. I have friends who are anti-fur activists. You can probably imagine what one of them would feel when discovering that she likes a fur-coat designer! And finally some concrete advice. Review your list of old likes regularly. Remove everything except those things you truly like and want to support. When you encounter a giveaway post like this, check the involved brand’s main page in Facebook by searching for the brand name. You will in most cases notice that the giveaway is a totally different page that just is named similarly. That’s a strong scam indicator. Use common sense. From the above you get an idea about what likes in Facebook are worth. Does it make sense to give away luxury cars for this? Don’t participate in scams like this. It might feel tempting, but remember that your chance to win is exactly zero. Spread knowledge every time you see a scam of this kind. Comment with a link to this post or the appropriate description on Hoax-Slayer or Snopes. Those sites are by the way fun and educating reading. I recommend spending some time there getting familiar with other types of hoaxes too. Read at least these two articles: Facebook car giveaway on Snopes and Facebook like-farming scams on Hoax-Slayer . Safe surfing, Micke
“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.
