80 Percent of Attacks in 2012 Were Redirects to Legitimate Sites…and 27 Percent of all Cybercrime was Linked to ‘Blackhole’ Exploit Kit
Sophos today released its Security Threat Report 2013, a detailed and interactive assessment of what’s happened in IT security for 2012 and what’s expected for 2013–from the ever-growing bring your own device (BYOD) movement to the increasing adoption of (and uncertainty around) the cloud to countless other security challenges faced by organizations of all sizes. The full report is available for download here.
Year in Review
2012 was a year of new platforms and modern malware—what was once a homogeneous world of Windows systems, is now a landscape made up of diverse platforms. Modern malware is taking advantage of these trends, creating new challenges for IT security professionals.
The increasing mobility of data in corporate environments has forced IT staff to bcome even more agile. 2012 was also a retro year driven by resurgence in traditional malware attacks, specifically malware distributed via the web. For example, more than 80 percent of attacks were redirects, the majority of which were from legitimate websites that were hacked.
Malware Attacks: Riskiest and Safest Countries
Unprotected computers are vulnerable to different kinds of malware attack. Exposure to the majority, but not all, comes from simply clicking on links in emails or browsing web pages that happen to be carrying malicious code. Although some websites are created with the intention of infecting visitors, legitimate websites continue to be a popular target for cybercriminals, as once they are compromised, they will infect completely unsuspecting internet users. Based on analyzed traffic, SophosLabs, Sophos’ global network of threat intelligence centers, has ranked the riskiest and safest countries for experiencing a malware attack:
Top 5 Riskiest Countries
Rank Country TER*
1 Hong Kong 23.54%
2 Taiwan 21.26%
3 UAE 20.78%
4 Mexico 19.81%
5 India 17.44%
Top 5 Safest Countries
Rank Country TER*
1 Norway 1.81%
2 Sweden 2.59%
3 Japan 2.63%
4 UK 3.51%
5 Switzerland 3.81%
*Threat Exposure Rate (TER): Measured as the percentage of PCs that experienced a malware attack, whether successful or failed, over a three month period in 2012.
A Look Ahead
While a large proportion of cybercrime continues to be opportunistic, Sophos believes that, in 2013, increased availability of malware testing platforms — some even providing criminals with money back guarantees – will make it more likely for malware to slip through traditional business security systems. As a result, we can expect to see an increase in the number of incidents where attackers have gained and sustained surreptitious access to corporate networks. Additional trends expected in the year ahead include:
- More basic web server mistakes
Due to an uptick in credential-based extractions, IT professionals will need to pay equal attention to protecting both their computers as well as their web server environment.
- More “irreversible” malware
More attacks will place a greater focus on the need for behavioral protection mechanisms as well as system hardening and backup/restore procedures.
- Attack toolkits with premium features
A continued evolution in the maturation of exploit kits, including premium features such as built in scriptable web services, APIs, and malware quality assurance platforms that appear to make access to high quality malicious code even simpler.
- Better exploit mitigation
Enhanced exploit mitigation will not mean the end of exploits, instead, the market will see a decrease in vulnerability exploits offset by a sharp rise in social engineering attacks across a wide array of platforms.
- Integration, privacy and security challenges
With GPS and near field communication (NFC) becoming more integrated into mobile platforms, expect to see a convergence in our digital and physical lives. This trend is identifiable not just for mobile devices, but for computing in general. In the coming year, watch for new examples of attacks built on these technologies.
“Two of the defining terms of 2012 are ‘empower’ and ‘evolve.’ Attacks and threats—on PCs, Macs and mobile devices—continue to evolve as does the technology to combat them,” said Gerhard Eschelbeck, CTO, Sophos. “As users demand more and better ways to do their jobs, IT continues to evolve, bringing forth a new set of operating systems and other advancements, replete with different security models and attack vectors, making it crucial for security technology to evolve, ensuring that end users are protected and empowered—no matter what platform, device, or operating system they choose.”
