40 Years of Malware – Part 4

40 Years of Malware - Part 42011 marks the 40th anniversary of the computer virus. Help Net Security notes that over the last four decades, malware instances have grown from 1,300 in 1990, to 50,000 in 2000, to over 200 million in 2010. Fortinet (FTNT) marks this dubious milestone with an article that counts down some of the malware evolution low-lights.

The Sunnyvale, CA network security firm says that viruses evolved from academic proof of concepts to geek pranks which have evolved into cybercriminal tools. By 2005, the virus scene had been monetized, and almost all viruses developed for the sole purpose of making money via more or less complex business models. According to FortiGuard Labs, the most significant computer viruses over the last 40 years are:

Botnets2007 – By 2007, Botnets have infected millions worldwide using Zombie systems to send spam to generate Denial of Service (DoS) attacks, compromised passwords, and data. By 2007 cybercriminals had developed a lucrative business model they were protecting. The attackers became more concerned about protecting their zombie computers. Until 2007, botnets lacked robustness, by neutralizing its unique Control Center (PDF), a botnet could be taken down because Zombies didn’t have anyone to report to (and take commands from) anymore. The Storm botnet was the first to feature a peer-to-peer architecture (PDF) to decentralize its command and control functions. At the peak of the outbreak, the Storm Botnet was more powerful than many supercomputers and accounted for 8% of all malware running in the world according to FortiGuard.

Koobface2008Koobface (an anagram for Facebook) spreads by pretending to be the infected user on social networks, prompting friends to download an update to their Flash player to view a video. The update is a copy of the virus. Once infected, users would serve as both vectors of infection for other social network contacts and as human robots to solve CAPTCHA challenges for cyber-criminals, among other things. Koobface is also the first botnet to recruit its Zombie computers across multiple social networks (Facebook, MySpace, hi5, Bebo, Friendster, etc). FortiGuard estimates that over 500,000 Koobface zombies are online at the same time.

Conficker2009Conficker (aka Downadup) is a particularly sophisticated and long-lived virus, as it’s both a worm, much like Sasser, and an ultra-resilient botnet, which downloads destructive code from a random Internet server. (We still see it pop-up from time to time at work). Conficker targeted the Microsoft Windows OS and used Windows flaws and Dictionary attacks on admin passwords to crack machines and link them to a computer under the control of the attacker. Conficker’s weakness is its propagation algorithm is poorly calibrated, causing it to be discovered more often according to Fortinet. In 2009 some networks were so saturated by Conficker, that it caused planes to be grounded, hospitals and military bases were impacted. Conficker infected bout 7 million systems worldwide.

Advanced Persistent ThreatAdvanced Persistent Threat (aka APT, Operation Aurora) was a cyber attack that began in mid-2009 and continued through December 2009. The attack was first publicly disclosed by Google (GOOG) on January 12, 2010, in a blog post. In the blog post, Google said the attack originated in China and was both sophisticated and well resourced and consistent with an advanced persistent threat attack. According to Wikipedia the attack also included Adobe (ADBE), Dow Chemical (DOW), Juniper Networks (JNPR), Morgan Stanley (MS), Northrop Grumman,(NOC), Rackspace (RAX), Symantec (SYMC), and Yahoo (YHOO). There is speculation that the primary goal of the attack was to gain access to and potentially change source code repositories at these high-tech, security, and defense contractor companies.

The definition of an Advanced Persistent Threat depends on who you ask, Greg Hoglund, CEO at HBGary told Network World an Advanced Persistent Threat is a nice way for the Air Force and DoD to not have to keep saying “Chinese state-sponsored threat.” He says,” APT is “the Chinese government’s state-sponsored espionage that’s been going on for 20 years,” Mr. Hoglund told Network World.

Stuxnet USB2010 Stuxnet‘s discovery in September 2010 ushered in the era of cyberwar. According to most threat researchers today, only governments have the necessary resources to design and implement a virus of such complexity. Stuxnet is the first piece of malware specifically designed to sabotage nuclear power plants. It can be regarded as the first advanced tool of cyber-warfare. Stuxnet was almost certainly a joint U.S. / Israeli creation for damaging the Iranian nuclear weapons program, which it did, by destroying a thousand centrifuges used for uranium enrichment.

To spread, Stuxnet exploited several critical vulnerabilities in Microsoft (MSFT) Windows, which, until then, were unknown, including one guaranteeing its execution when inserting an infected USB key into the target system, even if a systems autorun capabilities were disabled. From the infected system, Stuxnet was then able to spread into an internal network, until it reached its target: a Siemens industrial software system that run Iran’s Bushehr nuclear reactor and most likely intended to destroy or neutralize the industrial system.

Duqu2011Duqu is the current star in the world of malware but, as history shows, that fame will be short-lived. Just like fashion models, modern malware has a lifespan in the media eye of a couple of weeks to a couple of months, tops. They then fade into the shadow of more dangerous and advanced tools, according to Help Net Security.

Gary Warner, director of Research in Computer Forensics in the UAB College of Arts and Sciences blogged that Duqu is a data-stealing program that shares several blocks of code with Stuxnet. In fact, one of the two pieces of malware we’ve seen that is described as being Duqu is also detected as Stuxnet by some AV vendors.

Symantec disclosed in their report that one of the infections they were analyzing was infected via a Word Document that exploited the system using a previously unknown 0-day attack.

On November 3, 2011, Microsoft released a Microsoft Security Advisory (2639658) Vulnerability in TrueType Font Parsing Could Allow Elevation of Privilege. The advisory starts with an executive summary which says, in part:

Microsoft is investigating a vulnerability in a Microsoft Windows component, the Win32k TrueType font parsing engine. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. We are aware of targeted attacks that try to use the reported vulnerability; overall, we see low customer impact at this time. This vulnerability is related to the Duqu malware.

Every couple of years a new malware is crowned the most innovative or dangerous cyber threat in the wild. The anti-malware industry is built on a game of chicken between malware creators and anti-malware creators, with end users stuck squarely in the middle. As this series of articles has shown this game has gone on for 40 years since computers were bigger than many houses and were as user-friendly as the DMV.

Staff End Runs Security

When I am reclining in my Bach Seat, contemplating sharing tech services, my mind wanders to the consumerization of IT. The iPads have made an official beachhead and Skype has made it inside the perimeter. So I should not feel alone being concerned about security according to recent reports from Trend Micro and Cisco (CSCO).

employees bypass security roadblocks to engage in social networkingHelp Net Security reports that despite more workplaces regulating social networking site access, employees bypass security roadblocks to engage in social networking. The research by Trend Micro says that employees are finding ways around security roadblocks, making social networking a way of office life around the world. Trend Micro’s 2010 corporate end-user survey, found that globally, social networking at the workplace steadily rose from 19 percent in 2008 to 24 percent in 2010.

The survey also found that laptop users are much more likely than desktop users to visit social networking sites. Globally, social networking usage via laptops went up by 8 percent from 2008 to 2010. In the U.S., it increased by 10 percent In 2010, 29 percent of laptop users versus 18 percent of desktop users surveyed said they frequented these sites at work.

social networking is one of their organization's three greatest security risksThe survey also found that laptop users who can connect to the Internet outside of the company network are more likely to share confidential information via instant messenger, Webmail, and social media applications than those who are always connected to a company’s network.

A 2010 Cisco survey, which looked at the security impact of personal gadgets and social networking in the workplace, found that employees are consistently (Cisco’s words) finding ways around security policies. 68 percent of those surveyed by Cisco said that employees use unsupported social networking applications. Heavy use of unsupported collaboration, P2P, and cloud applications were also reported. More than half said social networking is one of their organization’s three greatest security risks. More than a third reported that their company lost data or experienced a breach because of employees using unsupported devices.

So why is Facebook such a problem for enterprises? For one, it is a huge time waster. Datacenter Knowledge reports that Facebook users spend a total of more than 16 billion minutes on social networking site Facebook per day. Facebook VP of Technical Operations Jonathan Heiliger stated that 3 billion photos are uploaded to Facebook each month and users view more than 1 million photos every second during a presentation at the Velocity 2010 conference

The more popular the social network, the more effective social networks become as malware distribution platforms. KOOBFACE, the “largest Web 2.0 botnet,” controls and commands compromised machines globally. This demonstrates the scale of the threat and emphasizes the need to educate users and implement strong policies.

Trend Micro says that trying to just prevent users from accessing social networks from work could potentially increase the risk to an organization as users look for ways around computer security possibly increasing the chance of exposure to security threats. The lesson, in Cisco’s view, is that you better find the technologies–and resources–to support personal devices and applications because they will be used regardless. “The best strategic approach is to focus less on restricting usage and more on effective solutions to ensure highly secure, responsible use,” said Fred Kost, Cisco’s director of security solutions.

Call me old-school but it seems that employees have always learned to work within reasonable company boundaries. Another option for those organizations that need web 2.0 in the organization should take a look at Palo Alto Networks who have developed a firewall that can block the wasteful parts of social media and leave some parts of the web 2.0 app accessible.

Consumer technologies evolve faster than the IT department budget, and it could be a constant game of catch-up trying to accommodate the latest rogue gadgets and widgets. Ultimately, rogue IT use is not so much a failure of technology, but a failure of policy and policy enforcement.

Facebook is Biggest Social Networking Risk

Facebook is Biggest Social Networking Risk Data from anti-malware vendor Sophos2010 Security Threat Report (PDF) says Facebook is the leader in privacy risks, spam, and other malicious activity. 60 percent of the respondents to a Sophos survey identified Facebook as the biggest security risk in social networking, followed by MySpace (18%), Twitter (17%), and LinkedIn (4%).

It is not surprising that users regard Facebook as the top risk. Facebook’s over 500 million users, offer criminals a cornucopia of personal data to exploit. “Computer users are spending more time on social networks, sharing sensitive and valuable personal information, and hackers have sniffed out where the money is to be made,” said Graham Cluley, senior technology consultant for Sophos.

Criminals have focused their efforts on social media

Sophos’ research shows that criminals have focused their efforts on social networking users in the last 12 months creating an “explosion” in social networking spam and malware complaints. Sophos found that 57% of social network users were spammed on one of the sites, an increase of 70 percent compared to last year.  They also found 36%  of social network users reported being sent malware, a 70% increase over last year. “The dramatic rise in attacks in the last year tells us that social networks and their millions of users have to do more to protect themselves from organized cybercrime, or risk falling prey to identity theft schemes, scams, and malware attacks,” Sophos’ Cluley added.

Three things working against Facebook users

There are three things working against Facebook users, themselves, malware, and Facebook. Facebook users typically give away more private information to Facebook than other sites. Though most people’s profiles it is possible to find out their first, last, and maiden names, where they live, where they went to school, and even worse, historical information like where they lived in the past. A lot of this private information is required on many online credit checks, providing a boom for criminals looking to exploit a user’s credit history or steal their identity.

The most common malware used on social networks is Koobface. Koobface can target all the popular social portals, including Facebook, MySpace, Bebo, Friendster, Tagged, and Twitter. According to the report, Koobface is capable of, “... registering a Facebook account, activating the account by confirming an email sent to a Gmail address, befriending random strangers on the site, joining random Facebook groups, and posting messages on the walls of Facebook friends. Furthermore, it includes code to avoid drawing attention to itself by restricting how many new Facebook friends it makes each day.

Another threat is Facebook applications. Criminals can create malicious Facebook applications designed to steal information and they can find holes in pre-existing applications and exploit them. Legitimate Facebook apps will give away your information if you allow them to (as I have written about here and here). Once an app has permission it can harvest all the information in a Facebook profile and send it to criminals. Before users grant an application access to all of their information, they should Google the publisher to see if they are legitimate or not. Any application that starts doing anything strange or suspicious should be removed immediately.

Facebook has tried to address these risks by issuing a new privacy policy. However, Sophos’ Cluley called it a step backward, because the new settings are “encouraging many users to share their information with everybody on the internet.” According to Facebook only 35% of their users actually customized their settings leaving 65% who presumably didn’t change their settings and continue to share valuable data, which is then used to propagate spam and malware.
