Threat report H2 2012

This time of the year is always interesting. It is the time when Labs looks back on the past half-year to summarize what has happened in the threat landscape. I can proudly announce that the report for H2 2012 has been published and is free for you to download and read!

The report is once again packed with highly interesting reading on the threats that we all face when using the net. And this report is not just a repetition of what has been published in the media. A compilation like this makes it easier to spot the trends and the big picture. Thanks guys for putting it all together! And of course for the continuous research effort that it is based on. (I’m not going to list all the names here, the full list of contributors can be found in the report.)

Here’s some teasers…

Botnets. ZeroAccess was easily the most prevalent botnet we saw in 2012, with infections most visible in France, United States and Sweden. It is also one of the most actively developed and perhaps the most profitable botnet of last year. Read more about ZeroAccess and botnets in general at page 15 – 20.

Exploits. Java was the main target for most of the exploit-based attacks we saw during the past half year. This is aptly demonstrated in the statistics for the top 10 most prevalent detections recorded by our cloud lookup systems. Learn more about exploits at page 25-27.

Banking trojans. With regards to banking-trojans, a botnet known as Zeus—which is also the name for the malware used to infect the user’s machines—is the main story for 2012. Browse to page 21-24 to read how the traditional way to rob a bank has become hopelessly old-fashioned.

The web. Common sense is still important when surfing, but it is becoming increasingly difficult to spot the dangerous places. Ad-networks are integrated in an increasing number of sites and can distribute malware through web portals that should be trustworthy. More about the web’s dangerous places at page 28-31.

Mobile devices. Did you know that there is malware on all commonly used mobile platforms? But Android has the questionable honor to lead the pack, and the others are far behind. The full story is on page 35-37.

The threat report covers all this and a lot more. Why not make sure that you are up to date on the threat scenario by continuing to the report. It is highly recommended reading.

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

AMA- 2nd December

5 of the best answers from @mikko’s reddit AMA

Fresh off his latest talk at at TEDxBrussels, our Chief Research Officer Mikko Hypponen sat down for a little session of "ask me anything" on reddit. You can read all of the questions people had for him and answers here. WARNING: There is a lot to go through. With over 3,200 comment's, Mikko's AMA ranks among one of the more popular threads in the subreddit's history. For a quick taste of what Mikko had to say about artificial intelligence, Tor, and Edward Snowden, here are slightly edited versions of 5 of our favorite questions and answers. How safe are current smart phones and how secure are their connections? - Jadeyard The operating systems on our current phones (and tablets) are clearly more secure than the operating systems on our computers. That's mostly because they are much more restricted. Windows Phones and iOS devices don't have a real malware problem (they still have to worry about things like phishing though). Android is the only smartphone platform that has real-world malware for it (but most of that is found in China and is coming from 3rd party app stores). It is interesting the Android is the first Linux distribution to have a real-world malware problem. Lots of people are afraid of the viruses and malware only simply because they are all over the news and relatively easy to explain to. I am personally more afraid of the silently allowed data mining (i.e. the amount of info Google can get their hands on) and social engineering style of "hacking". How would you compare these two different threats and their threat levels on Average Joes point of view - which of them is more likely to cause some harm. Or is there something else to be more afraid of even more (govermental level hacks/attacks)? - BadTaster There are different problems: problems with security and problems with privacy. Companies like Google and Facebook make money by trying to gather as much information about you as they can. But Google and Facebook are not criminals and they are not breaking the law. Security problems come from criminals who do break the law and who directly try to steal from you with attacks like banking trojans or credit card keyloggers. Normal, everyday people do regularily run into both problems. I guess getting hit by a criminal attack is worse, but getting your privacy eroded is not a laughing matter either. Blanket surveillance of the internet also affects us all. But comparing these threats to each other is hard. Hi, Mikko! Do you subscribe to Elon Musk's statements and conceptions of AI being the single biggest threat to humans? - matti80 Elon is the man. I've always thought of Tony Stark as my role model and Elon is the closest thing we have in the real world. And he's right. Artificial Intelligence is scary. I believe introducing an entity with superior intelligence into your own biosphere is a basic evolutionary mistake. Europol's cybercrime taskforce recently took down over a hundred darknet servers. Did the news shake your faith in TOR? - brain4narchy People use Tor for surfing the normal web anonymized, and they use Tor Hidden Service for running websites that are only accessible for Tor users. Both Tor use cases can be targeted by various kinds of attacks. Just like anywhere else, there is no absolute security in Tor either. I guess the takedown showed more about capabilities of current law enforcement than anything else. I use Tor regularly to gain access to sites in the Tor Hidden Service, but for protecting my own privacy, I don't rely on Tor. I use VPNs instead. In addition to providing you an exit node from another location, VPNs also encrypt your traffic. However, Tor is free and it's open source. Most VPNs are closed source, and you have to pay for them. And you have to rely on the VPN provider, so choose carefully. We have a VPN product of our own, which is what I use. If you ever met Snowden what would be the first question you would ask him? - SaPro19 'What would you like to drink? It's on me.' Cheers, Sandra
