I had the honor recently of moderating a virtual roundtable discussion on the top Internet security trends from 2009 and what we expect to see in the security threat landscape in 2010. Funny thing about security predictions—you hope they won’t come true, but expect them to anyway. The roundtable featured expert panelists Paul Wood (Senior Analyst, MessageLabs Intelligence, Symantec) and Zulfikar Ramzan (Technical Director, Symantec Security Response). They each have unique insights into the world of cybercrime, spam, phishing attacks, and other cyberthreats that plague us all.
 
We want to give a big thanks to everyone who joined in to listen to our experts, and we hope you found it interesting. For those of you who couldn’t make it, please take a few minutes to listen to the podcast of the actual roundtable.

We are monitoring new malicious attacks that look similar to the fake "Microsoft Outlook reconfigure" spam campaign messages we have been observing for the last couple of months. That malicious campaign was followed by attacks on social networking sites, transforming from malicious code attacks into URL-based phishing attacks. These new attacks have similar traits, such as the spoofed “From” headers, which aggressively target and baffle enterprise users, and a subject line that is intended to cause panic (for obvious reasons—have a look at the example image below).

As seen in the message above, the mail attachment is a zipped file named “utility.zip” that extracts an executable detected as Trojan.Dropper by Symantec antivirus. Using...

Zeus is a botnet package that allows for the easy creation and command and control of a botnet.  We've discussed Zeus previously in Zeus, King of the Underground Crimeware Toolkits. The main purpose of Zeus is to steal online credentials such as online banking passwords, but it can be configured to steal passwords from any online site. 

Today, the BBC is reporting that police in the UK have arrested two suspects in relation to Zeus. While the details are preliminary, the two likely appear to be users of the Zeus botnet package rather than the actual creators, and thus the prevalence and usage of Zeus is likely to continue.

We've created a research paper providing more in-depth information on Zeus, including how the bot is created, what functionality it has, and additional screenshots on...

Yes, it’s a cheap trick and not even close to original. But the lesson here is that even obvious social engineering tricks can get people to click on a link. We can’t help ourselves. We love to click. Clicking on links and attachments that are accompanied by just the slightest bit of social engineering appears to be a basic human need. I expect it to show up in a revision of Maslow’s Hierarchy of Human Needs any day now—behind love, but certainly ahead of safety.

I do have a point to all this. Two actually. As we compiled the Security Trends to Watch in 2010, what occurred to me is that the people who most needed to read this information never will. At least not without some social engineering on my part. And since social engineering plays such a prominent role in future trends, it seemed appropriate. So I’ve decided to use this little trick to get people to...

The Security Response team has compiled the top security trends of 2009. We pulled data from the Global Intelligence Network and the experiences of the thousands of analysts and security experts at Symantec to come up with the top trends for the year. While none of these trends will be a surprise to anyone even casually following the threat landscape, when compiled and summarized, it is clear that the breadth of security problems in the past year was pretty stunning.

For example:

•    Toolkits and threat recycling have made malware easier to create than ever
•    Polymorphic technology is being applied to make threats harder to catch
•    Botnets, large and small, are used as the foundation of attacks making most attacks complex
•    All major news events are used for social engineering
•    Major brands are being appropriated by cybercriminals...

On November 4, 2009, Marsh Ray published detailed information about a vulnerability that affects the TLS/SSL protocols and allows for limited man-in-the-middle (MITM) attacks. We say “limited” because the attack exploiting this issue would be different from traditionally viewed MITM attacks, which would involve an attacker placing themselves in the middle of the SSL session between a client and a server and being able to intercept, view, and modify any requests or responses exchanged by the two communicating parties. In an attack using this recent TLS vulnerability, due to the way SSL-enabled applications handle the session-renegotiation process, an attacker may inject arbitrary plaintext into the beginning of the application protocol stream. This can affect multiple protocols that can communicate over an SSL session, such as HTTPS, IMAP, POPS, SIP, etc. Note that in this attack, the attacker would have no ability (at least...

Finally, some help with explaining Internet security to my non-geek friends! The Guide to Scary Internet Stuff video series will hopefully make my life a little easier. Explaining the intricacies of Internet security is a challenging task. I often have difficulty explaining to my non-technical friends and relatives why they need to know about risks on the Internet. On top of that, I sometimes discover that my advice has fallen on deaf ears as I inevitably fix their computers after a click on a spam or phishing link, or after they have not run Windows Update or updated their antivirus software in a while.

Although this is not the normal technical type of material that we post here on the Security Response blog, when Dominic Cook from our UK PR team showed me these, I immediately thought they were worth a post. The animations are fun, but most of all I think my friends will understand them, remember some of the advice,...

When trawling the Web today we came across a website that has been compromised and rigged so that it is returned in search engine results for many different search terms. The site in question belongs to a UK-based company that specializes in hiring out holiday homes and is a legitimate business. However, the site has been compromised and is being used in a major ongoing SEO-based misleading applications attack, and has been for some time now. As you can see in the sample search results below, you may wonder what college football, a Ukraine vs. Greece soccer match, Penn State basketball, and Robin Williams have to do with renting a holiday home—and with good reason, too.

Phishing attacks jeopardize users’ personal information, including banking credentials. The huge gain that Internet miscreants receive from these attacks drives them to think of newer and more effective bait to phish users’ personal data. To carry out their plans, spammers most commonly abuse new security services/features provided by legitimate companies.

Many financial institutions have already started providing a pin/password generator device (also known as “secret reader”) for their customers to conduct secure online transactions. The device generates random pin codes after a specified interval of time. In a recent phishing attack the fraudsters promoted a similar secret reader.

This fake message claims that a bank has developed a secret reader that generates a password of 10 alphanumeric characters. The message also targets existing customers who are already using this device provided by the bank, and informs them that existing device will...

If a hacker managed to hack into your blog or website, what could they possibly do? They could insert malicious iframes or JavaScript code into your Web pages. Probably even attempt to steal some data. But most likely they would "search engine optimize" your website. Can this be true? Well, let me explain more.

Search engine optimization (SEO) is a collection of techniques used to achieve higher search rankings for a given website. "Black hat SEO" is the method of using unethical SEO techniques in order to obtain a higher search ranking. These techniques include things like keyword stuffing, cloaking, and link farming, which are used to "game" the search engine algorithms.

So what does a hacker gain from all this? Why would a hacker help you achieve a higher search engine ranking? Quite the contrary; he is helping himself.

What the hacker actually does is add numerous additional Web pages to your website. Let’s call each of...

The first iPhone worm, known as iPhoneOS.Ikee, recently hit the news everywhere. The purpose of this worm was to show that jailbroken iPhones had a flaw that could be easily exploited. The consequences of this worm were minor since the author decided to simply Rickroll users who became victims of this attack. However, there were many warnings that the publicly released code could easily be altered so that consequences were not so benign.

Given the implications—and this being a hot topic—reports are surfacing about a hacktool that can be used to attack jailbroken iPhones. This tool is taking advantage of the same default SSH password that iPhoneOS.Ikee does, but put plainly, this is not another worm. We’re looking at...

Hello and welcome to this month’s blog on the Microsoft patch releases. This is a moderate month—the vendor is releasing six bulletins covering a total of 15 vulnerabilities.

Three of the issues are rated “Critical” and affect Web Services on Devices API, License Logging Server, and the Windows kernel. An attacker could exploit these issues remotely to gain complete control of a vulnerable computer.

The remaining issues, rated “Important”, affect Excel, the Windows kernel, Office, and Active Directory. Although these are only rated “Important” by Microsoft, we consider the Office and Excel issues quite serious and advise customers to apply updates as soon as possible.

As always, customers are advised to follow these security best practices:

- Install vendor patches as soon as they are available.
- Run all software with the least privileges required while still maintaining functionality.
- Avoid handling files from unknown or...

Trojan.Clampi is an interesting threat, which we described in many blog entries over the past month. We’ve now compiled these entries, along with some new material, into a research paper—Inside the Jaws of Trojan.Clampi.

In a nutshell, Clampi is an Infostealer threat. Its executable can be seen as a host for separate modules, containing the real payloads of the threat. These modules are heavily protected from reverse-engineering as well. The functionalities range from banking-site password stealing, to local credential gathering, to a SOCKS proxy. The communication with Clampi’s command & control servers, the “Gates”, uses HTTP and is encrypted. Clampi...

One thing I see again and again in this job is that people usually don’t think about security until after they are hit with an incident. Companies create disaster recovery plans after the disaster. They come up with incident response teams after the incident. And consumers get antivirus software after they’ve had a virus infect their system.

People, here is a chance to turn that all around. We’ve seen several incidents of mobile phones being hacked. So far it’s been by old school hackers, those that are doing it just to prove that it can be done. But history shows us that the cyber criminals follow closely behind the old school hackers, and they will not be doing it for kicks—they’ll be doing it to rip you off.
 
Security professionals approach any situation like this by a risk assessment; in other words, they try to figure out what bad things could happen. Then they can hope for the best, but prepare for the worse. If...

On the heels of a similar iPhone attack by a Dutch teenager, an Australian hacker (using the same technique) has written the first iPhone worm for jailbroken iPhones. The worm has been dubbed “Ikee” and uses the default SSH password of jailbroken iPhones to log in and spread. Please note that this worm does not impact iPhones that have not been jailbroken.

Many users who have jailbroken their iPhones in order to customize them have not changed their SSH password, allowing others to log in to their phone. In the case of Ikee, the worm scans random IP ranges and also specifically targets Optus, Vodafone, and Telstra's IP ranges, which are the common telephony providers in Australia. Once a vulnerable iPhone is found, the worm changes the wallpaper to a picture of Rick Astley (a prank known as Rickrolling), deletes the SSH daemon, and begins scanning the network for other vulnerable phones. Note that some of these telephony networks use NAT (network...
