ZEUS Malware Infects Globally Million PCs

Just when security companies have developed new ways of dealing with the infamous Zeus Trojan, a variant characterized as the "Son of Zeus" has arisen. Worse yet, the variant has the trait of being virtually undetectable by conventional antivirus applications.

About the Zeus Trojan and MS Windows

The Zeus Trojan made headlines back in 2009 as a "highly customizable" tool for hackers. It's main mission is to sniff out financial information and break into online bank accounts. Security experts estimate that the Zeus Trojan has been used to infiltrate tens of thousands of PCs around the world. Owners of infected PCs are unaware their computers are even infected, with the majority (if not all) of infections targeting MS Windows PCs.



Zeus a Persistent Threat, Continues to Morph

The Zeus Trojan continues to be a persistent threat and was responsible for stealing 3 Million US Dollars (as of October 1st, 2010) and a reported 6 Million British Sterling from UK bank accounts (Source: itnews.com.au).


The latest revision of the Trojan ("Son of Zeus") Trojan is codenamed "TSPY_ZBOT.BYZ," according to security experts. The reason why it is able to slip by conventional antivirus programs is because it imports a large number of application programming interfaces (API's), making it difficult to know (or even predict) where it will strike next.

New Variant More Efficient Than Original

As is the case with most types of malware variants, the newer version is somewhat different (and much more efficient) than its predecessor. It is also different in its compression and can foil a detection system based on calculable entropy. In a nutshell, calculable entropy pertains to finding where in the viral code certain trigger routines might be hidden and gives TSPY_ZBOT.BYZ its "undetectable" status.


With most forms of malware, security companies are able to isolate the virus in a virtual "sandbox" and track how the code was executed, what system changes it made and any network traffic it generated. Thus, Zeus (in all of its forms) refuses to "play in the sandbox". (Source: itnews.com.au)

Conventional Antivirus Not Sufficient

This spells disaster for most security companies whose primary focus is to keep their customers safe. As Trend Micro research engineer Julius Dizon expressed, "To properly guard against this threat, conventional antivirus is not sufficient. Only improved detection techniques and proactive blocking of the websites, working together, can protect users."


Razorpoint Services Can Protect You
Mainstream network security providers are fine for organizations looking to "check the box." Most can neutralize the average hacker and help organizations comply with a security checklist. They apply their technologies and processes and fix the obvious problems. But these organizations usually are not suited to keep pace with the world's most sophisticated cyber criminals. Razorpoint is.

Passwords: To Secure or Not to Secure

Passwords have been in use since ancient times but it seems like the periodic controversy over whether or not to use them really gained momentum with computing. The latest view turned up in the SmartPlanet blog. There you’ll find Joe McKendrik waxing poetic about a Microsoft study that basically says the cost of passwords outweighs the risks. Wrong!

There is a perception that coming up with unique, strong passwords is a burden. And adding to this perceived difficulty are things like creating a new password, on a regular basis, that can never be the same as a previously used one, is in insurmountable task.

Reading that above blog posting made me feel as if i had taken a time machine to work that morning. Really? Passwords are always hard to remember? Really? So, let's see, users (the de facto weakest link in any security chain) should just be allowed to do whatever they like because, as soon as the enormous burden of password creation and retention is removed from their hectic schedules, productivity skyrockets. Really? Facebook, YouTube, and MySpace anyone? Oh, and finally, a "top security researcher from Microsoft?" Don't get me started.

Flux-capacitor and time circuits set back to 2010, cybercrime is about to surpass illegal drug trafficking as a moneymaker for criminals. Yes, you read that correctly. Cybercriminals can make more money than drug dealers. Hello? Things are getting worse, not better. While end user failure enables a large part of the rise in cybercrime, corporate ineptitude still plays a key role. Training and basic understanding of network and cybersecurity (strong passwords included) is pitifully low. On regular security engagements, my team and I are routinely stunned at what we find. Whether it is a small, medium, or even a large global firm, undoubtedly we achieve a mind blowing, head shaking dose of "I can not believe what I'm seeing." Dated or non-existent security policies, unmonitored and out-of-date security technologies (firewalls, VPN, IDS, etc.), understaffed and undertrained IT departments tasked with a security role, and a common company-wide malaise regarding proper network security. Routinely, we're able to obtain identity information, bank account access, transaction histories, internal pricing lists, etc. Billions spent on network security, and we're going backwards.

I agree that users get bombarded with different, often unclear and untrue, messages about security and how to handle certain situations (phishing emails and web sites, spoofed SSL certificates, even social engineering). A big reason for this is the wrong people get tasked with designing and disseminating a company's security policy. Security personnel should be doing this, not IT personnel. Perhaps a topic for another article, but Security is not an IT issue, it is a management issue.

Growing cybercrime profitability shows us that current and past security practices are severely flawed. But, stopping the use of one of them (passwords) isn't a solution. They should be enhanced. Yes, use a credentialed mechanism for secure access to data, sites, services, etc. But perhaps instead of forcing the average user to produce and remember cryptic passwords constantly, teach them to use patterns on a standard QWERTY keyboard. Examine this password: 0ok9ij)OK(IJ - It has all the password characteristics of a security manager's dream. But how on earth is someone going to remember that? Look at your keyboard and notice that those characters are in a pattern. Start with the zero and then move down and to the left; you get the "o" and the "k". Then move from the zero to the 9 and go down again for the "i" and "j". Then do the same two downward patterns while holding the Shift key. Dream password? Solved. Want another password? Pick a new starting point and a new directional pattern. What to make it unique to a particular site? Add a letter before or after that password ("E" for email, "I" company intranet, "A" for Amazon.com, etc.). You now have a strong password with nothing to remember but a keyboard pattern.

Strong passwords aside, however, two-factor authentication is another technology that can help with the ongoing battle of user password management. Two-factor authentication is something you have, and something you know. You can "have" a random password generator token on your key chain, and you can "know" a sufficiently strong password that goes with it. These and other technologies are available today in an attempt to curb cybercrime's expanse.

If it’s your business you’re securing, you can ignore the reports that say passwords are not cost effective. Instead, invest in employee education. Truly relevant, informative, actionable, employee security education. A good investment always yields solid returns. If you want to keep your support costs down while keeping your company secure, teach your employees the importance of good password habits along with an overarching mindset of reality-based security awareness.

While companies have consistently failed at these things, the future is now and big differences can be made. I believe we can only go up from here.

Tabnabbing: A new type of phishing

Check out this page at azarask.in. They demonstrate a new method of phishing. A page you are looking at can auto-switch to a page that resembles a page of a trusted website such as gmail, facebook, paypal, or online banking. Part of the attack involves changing the favicon of the page and monitoring for page inactivity.

Widespread attacks continue against WordPress sites

Owners of self-hosted WordPress based websites should make sure that their FTP and wordpress passwords are secure. Also review your WordPress installation to make sure that it is up to date. The current version is 2.9.2. Sites hosted on WordPress.com are not affected.

Intruders in recent weeks have hacked a large number of websites created through the WordPress blogging platform to spread malware, with another major campaign launched on Thursday, security researchers said.

In addition to WordPress blogs, websites created with other PHP-based platforms, including the Zen Cart eCommerce solution, were affected by the attacks, Regina Smola, co-founder of WPSecurityLock, a provider of WordPress security services, told SCMagazineUS.com on Tuesday.

Attackers injected malicious JavaScript into the sites, causing visitors to be redirected to scareware domains that attempted to trick users into installing a virus, she said.

1.5 million stolen Facebook IDs up for sale

A hacker named Kirllos is offering to sell the accounts in an underground forum for 2.5 cents per account.

A hacker named Kirllos has a rare deal for anyone who wants to spam, steal or scam on Facebook: an unprecedented number of user accounts offered at rock-bottom prices.


Researchers at VeriSign's iDefense group recently spotted Kirllos selling Facebook user names and passwords in an underground hacker forum, but what really caught their attention was the volume of credentials he had for sale: 1.5 million accounts.

IDefense doesn't know if Kirllos' accounts are legitimate, and Facebook didn't respond to messages Thursday seeking comment. If they are legitimate, he has the account information of about one in every 300 Facebook users. His asking price varies from US$25 to $45 per 1,000 accounts, depending on the number of contacts each user has.

To date, Kirllos seems to have sold close to 700,000 accounts, according to VeriSign Director of Cyber Intelligence Rick Howard.

Hackers have been selling stolen social-networking credentials for a while -- VeriSign has seen a brisk trade in names and passwords for Russia's VKontakte, for example. But now the trend is to go after global targets such as Facebook, Howard said.

Facebook has more than 400 million users worldwide, many of whom fall victim to scams each day. In one such scam, criminals send out messages from a compromised account, telling friends that the account's owner is trapped in a foreign country and needs money to get home.

In another, they send Web links that lead to malicious software, telling friends that it's a hilarious or sensationalistic video.

"People will follow it because they believe it was a friend that told them to go to this link," said Randy Abrams, director of technical education with security vendor Eset. Once the malware gets installed, criminals can steal more passwords, break into bank accounts, or simply use the computers to send spam or launch distributed denial of service attacks. "There's just a plethora of things that people can do if they can trick people into installing their software," he said.


Kirllos' Facebook prices are extremely cheap compared to what others are charging. In its most recent Internet Security Threat Report, Symantec found that e-mail usernames and passwords typically went for between $1 to $20 per account -- Kirllos wants as little as $0.025 per Facebook account. More coveted credit card or bank account details can go for much more, ranging between $0.85 to $30 for credit card numbers to $15 to $850 for top-quality online bank accounts.

Is your company social networking?

At the RSA Security conference during the week of March 1st, one of the topics of discussion was securing networks in a web 2.0 world (http://www.itworld.com/security/98911/tweet-social-network-security-risky-business?page=0%2C0&source=ITWNLE_nlt_today_2010-03-04.

Facebook, Twitter, LinkedIn and other social networking sites were until recently considered to be productivity killers. Most companies blocked access to these websites for their employees to make sure their staff members were not using company resources on frivolous time-wasters.

It is a good idea to block access to these sites for another reason. Social networking sites are just another point of exposure to malware, phishing attempts, and viruses. Everyone agreed that it was just best to keep your employees away from social networking.

However, last year marked a turning point in social networking. Employees in sales, HR, customer service and marketing need to use social networking sites to do their jobs. Corporations are now looking to open their doors to social networking, but how do you protect your company from malicious attacks?

Our take on the situation? Its not time to open the floodgates. Social networking is still potentially dangerous.

Your company should continue to block access to Facebook, Twitter and LinkedIn for most employees. Access should be granted on an individual or departmental basis, and only sparingly using monitored firewall, IPS or Application Security Gateway rules. Check Point and Tipping Point offer good solutions in these areas.

Cybercriminals love social networks because there is a false sense of being in a trusted, safe zone. Employees who do have access to social networking need to be educated that:

  • There is no privacy anywhere on the web. They should assume that anything posted on a social network may somehow become public. Trade secrets are at risk as well as your corporate brand.
  • All links should be treated suspiciously. Social networks use link shortening services like bit.ly and tinyURL. It's impossible to know where such a link will take you. It could be a phishing site that will enable someone to take over your account, steal your information or install a virus or malicious code on your computer.
  • All third party applications should be treated suspiciously. Twitter and Facebook offer thousands of applications that they do not take responsibility for. Be wary when installing one, or giving access to your account.
  • Finally, consider heavily what information you add to your public or semi-public social networking profiles. Remember that things like "High School attended," "Birth Date," "Pet Names," "Sibling Names," etc. are all things used by banks and credit institutions to validate your identity. You wouldn't hand out this information to strangers on the street, would you? Why, then, do people gleefully post this online? I'm actually surprised Facebook doesn't have a "Mother's Maiden Name" field.

There is No Security Patch for Stupidity

At Razorpoint, we spend a lot of time trying to stay ahead of malicious attackers and cybercriminals. We track the newest, most advanced techniques so that we can work with our customers to repel attacks. That's why we were floored by this article:

http://www.businessweek.com/news/2010-02-18/global-hackers-breached-2-400-companies-security-firm-says.html


According to Bloomberg News "hackers infiltrated the computer networks of more than 2,400 companies in almost 200 countries over an 18-month period." When we took a closer look at these attacks we noticed something very interesting:

"The attack uses a piece of software called ZeuS, designed in Eastern Europe, that takes control of large numbers of computers. These so-called botnets of computers are deployed to extract login and personal information related to e-mail, financial and social-networking Web sites."



ZeuS (aka Kneber) is a bot that steals information by keystroke logging. This method of infiltration is over 10 years old and it should not work anymore. Yet it does - because users continue to fall for the same dumb tricks. They open attachments to email that they shouldn't. They respond to phishing emails.

ZeuS and other bots now control more than 100 million computers worldwide. ZeuS targets login credentials for online social networks, e-mail accounts, and banking. Anti-virus software may not offer protection. The primary way to prevent infection is to offer training and security awareness to prevent your employees from clicking on hostile or suspicious links in email and in social networks.

Razorpoint knows that the Internet is still a target-rich environment. While there isn't a security patch for stupidity you can help protect your company by employing our endpoint client protection service (Rz.Endpoint). Additionally, companies should have regular comprehensive security assessments conducted in an effort to stay ahead of attacks like this.
