Security

In the security industry we often focus heavily on new technologies and shiny new software, and forget that so much of what we see is dependent on the person behind the computer. Today, a co-worker of mine was sent an email from someone she doesn’t know, with the following text: “I’m writing this with tears in my eyes,my fam and I came down here to Wales,United Kingdom for a short vacation unfortunately we were mugged at the park of the hotel where we stayed,all cash,credit card and cell were stolen off us but luckily for us we still have our passports with us. ...

There is a risk to computer security from governments. Regulatory changes, even if they are very positive measures, can impose huge demands on an enterprise (i.e. HIPPA, Sarbanes-Oxley, California’s law requiring notification of customers whose personal information is hacked on company sites.) The “government” risk can get no bigger than the clash of Google and the government of China over the censorship issue. The world suspects that the Chinese government or its proxies were behind a campaign of hacking against Google and other major U.S companies several months ago. Google reacted to the hacks by saying in January that it would stop censoring search results for web users in China. Monday it said it would move to Hong Kong. ...

Not so long ago, examples of fake Firefox websites / downloads were in the news with the sites involved serving Hotbar installs. It seems the tactic of offering up Firefox (but giving you something else entirely) is going to be around for a little while. Below is a site promoting a Firefox .xpi called “The Dislike Button”, designed to let you add an “I dislike this” note to Facebook posts: ...

Mozilla Foundation has released version 3.6.2 of its Firefox browser a week early. The group had said the update would be available March 30. The update fixes a widely reported vulnerability (CVE-2010-1028) that prompted Germany’s CERT to advise Web users to switch to another browser until a fix was made. (My blog post “Germany’s CERT warns against Firefox use” ) Intevydis researcher Evgeny Legerov had found that Wide Open Font Format decoder in Firefox had an integer overflow in its font decompression mechanism. The flaw involved a memory buffer that was too small to handle a downloadable font. Legerov had found that exploiting the vulnerability could crash a victim’s browser making it possible to run arbitrary code on the system. ...

Älypää, a popular Finnish game and quiz site, announced a database breach late last night. Over 127,000 account names and passwords were leaked. The site has currently suspended access and doesn’t maintain any personal details but Älypää users should determine whether or not they recycle their passwords elsewhere. If so, those accounts are at risk of being hacked. CERT-FI guidelines can be found here. Here’s a list of the top 20 domains on the list: ...

We found this interesting and malicious little mechanism. The hosts file on a machine under investigation was modified to redirect the victim’s browser to a well known legitimate site (in this case google.com) whenever he attempted to contact a list of nearly 400 sites. The list was a “Who’s Who” of the anti-malware world – most places where someone with an infected machine would go to get help. The altered hosts file he found contained many lines beginning with ‘#’ followed by gibberish. These would be seen as comments by any browser and ignored. Concealed among the commented lines are lines containing the domain name redirections. When the commented lines are stripped, we find all the listed security related websites being redirected to “209.85.129.99” which is the IP address for google.com. ...

We previously reported a phishing attack on the Indian Income Tax Department. Phishing emails boasting of tax refunds were sent to users in an attempt to entice citizens to enter their credentials on a bogus website. Recently, new attacks have been observed in which the phishing website states that taxes can be paid online. As the fiscal year in India draws to an end, more people are rushing to pay taxes before the deadline. ...

Hi folks, One of our researchers recently discovered that the Liberty exploit kit included a fairly new exploit from November 2009 … http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3867 . The fact that there was something fairly new in terms of exploits was interesting to start with, but then we looked at the text on the exploit page…. Lehman Brothers?! Coffee Party??!! Holy Activists, Batman!!! It’s politically motivated!!!! Then we looked at the stats page (all these toolkits come with a sophisticated admin page), and saw that the top referrer was ad.yieldmanager.com! Holy Advertisers, Batman! Activists who know how to use exploit kits, _and_ the ad network!!! ...

Yesterday there was a volcanic eruption in Iceland, near the Eyjafjallajoekull glacier, that has led the Icelandic authorities to declare a state of emergency in southern Iceland. People living nearby have been evacuated in case of glacial melt water flooding and the airspace near the now active volcano is effectively closed off. As you have probably already guessed, any event which commands a high level of public interest will be pounced on quickly by the makers of fake antivirus software in order to make a quick buck. This incident is no exception. ...

Generally speaking, most website defacements I see tend to look the same with political activist Y decrying political activist Z, or leet hax0rs posting up a mile-long shoutout list to their crew. This one is, er, a little different – a defacement of what appears to have been a site involved in fish logistics and / or preservation, fish2see(dot)dk. I can only imagine the horror on the face of the site admin who woke up this morning to be confronted by this: ...

If you have children that play Neopets, you might want to warn them about this website or insert it into a blocklist of your choosing. The site is Neopoints(dot)tk, and promises lots of free Neopoints related items, with the help of a cute mascot called “Tuma the Draik”. I think there was a Norwegian prog rock group from the 70s called that, but I could be wrong. Of particular note here is the fact the site claims to offer “free magic paintbrushes”. These items are incredibly rare in Neopets land, and an excited child could easily wander into this particular trap as a result. ...

We’re investigating a series of SMS Worms, found in the wild in China. Known as Trojan:SymbOS/MerogoSMS, these worms try to spread on Symbian Series 60 3rd Edition devices. Symbian continues to be by far the most common smartphone operating system in the world. These worms spread by sending text messages to other phones. These text messages contain variable messages (in Chinese), and a link to a website. If the link is followed, user is prompted to install an application – infecting the phone and restarting the SMS spreading. ...

Do you know what the latest version of Adobe’s Flash Player is? If you don’t, you may very well fall for this: Flash Player 11? There are more than 3 million pages linking to this alleged version 11: Most pages are from unsanitized forums, but there is even a Google Ad for it! Ooooops…. The screen below depicts the social engineering trick: What appears to be an X-rated video with a Windows Media Player logo (that is odd!). ...

I have seen a lot of these lately. This one currently doing the rounds tries to dupe the reader into thinking that the International Monetary Fund (IMF) wants to use their accounts to transfer money meant for charity. In the email. the IMF (supposedly) wants to transfer $10 Million into the reader’s account using NatWest Bank. The contact details within the Bank are given as follows: Name: Mr. Donald Miller (Co-founder) Office Address: 11 El Shams Bldgs., 8th District Nasr City E-mail: Bernisecharityfoundationimf ‘at’ gmail.com Tel: (+44) 7031-939-750 Fax: (+44) 7011830323 ...

Today we are going to take a closer look at bots and botnets. On the black market, selling bots and botnets is quite profitable, which makes creating them a popular activity for criminals. It helps that bot sources and creation kits are available on the Internet, allowing even script kiddies to create their own botnets. Another reason bots get created is that some people who get bored in their daily lives tend to do things that in their opinion might earn them respect or admiration in front of their peers or in various Internet chat rooms. ...
