Symantec Internet Security Threat Report Reveals Increase in Cyberespionage
Attackers target small businesses and suppliers to hit large organisations;
Consumers also vulnerable to ‘ransomware’ and mobile attacks
SYDNEY, Australia – April 16, 2013 – Symantec Corp.’s (Nasdaq: SYMC) Internet Security Threat Report, Volume 18 (ISTR) today revealed a 42 percent surge during 2012 in targeted attacks compared to the prior year. Designed to steal intellectual property, these targeted cyberespionage attacks are increasingly hitting the manufacturing sector as well as small businesses, which are the target of 31 percent of these attacks. Small businesses are attractive targets themselves and a way in to ultimately reach larger companies via “watering hole” techniques. In addition, consumers remain vulnerable to ransomware and mobile threats, particularly on the Android platform.
“This year’s ISTR shows that cybercriminals aren’t slowing down, and they continue to devise new ways to steal information from organisations of all sizes,” said Peter Sparkes, Director of Managed Security Services, Symantec, APJ. “The sophistication of attacks coupled with today’s IT complexities, such as virtualisation, mobility and cloud, require organisations to remain proactive and use ‘defense in depth’ security measures to stay ahead of attacks.”
ISTR 18 Key Highlights Include:
Australia increasingly targeted by cyber criminals
Australia experienced an increase in the level of cybercrime activity in 2012 and is now ranked the 21st most targeted nation for cybercriminals, up three places from 24th in 2011. Over the last year, Australia’s ranking increased in the areas of Spam, Malicious code and Network Attacking Countries, indicating a heightened level of activity in these areas compared with 2011. Peter Sparkes, Symantec’s Director for Managed Security Services in APJ, said, “As a nation of early adopters with a strong economy which uses technology to remain competitive, Australia is turning out to be an attractive target for cybercriminals.”
Small Businesses Are the Path of Least Resistance
Targeted attacks are growing the most among businesses with fewer than 250 employees, which are now the target of 31 percent of attacks, up from 18 percent in 2011. While small businesses may feel they are immune to targeted attacks, cybercriminals are enticed by these organisations’ bank account information, customer data and intellectual property. Attackers hone in on small businesses that may often lack adequate security practices and infrastructure.
Web-based attacks increased by 30 percent in 2012, many of which originated from the compromised websites of small businesses. These websites were then used in massive cyber-attacks as well as “watering hole” attacks. In a watering hole attack, the attacker compromises a website, such as a blog or small business website, which is known to be frequently visited by the victim of interest. When the victim later visits the compromised website, a targeted attack payload is silently installed on their computer. The Elderwood Gang pioneered this class of attack; and, in 2012, successfully infected 500 organisations in a single day. In these scenarios, the attacker leverages the weak security of one business to circumvent the potentially stronger security of another business.
Manufacturing Sector and Knowledge Workers Become Primary Targets
Shifting from governments, manufacturing has moved to the top of the list of industries targeted for attacks in 2012. Symantec believes this is attributed to an increase in attacks targeting the supply chain – cybercriminals find these contractors and subcontractors susceptible to attacks and they are often in possession of valuable intellectual property. Often by going after manufacturing companies in the supply chain, attackers gain access to sensitive information of a larger company. In addition, executives are no longer the leading targets of choice. In 2012, the most commonly targeted victims of these types of attacks across all industries were knowledge workers (27 percent) with access to intellectual property as well as those in sales (24 percent).
Mobile Malware and Malicious Websites Put Consumers and Businesses at Risk
Last year, mobile malware increased by 58 percent, and 32 percent of all mobile threats attempted to steal information, such as e-mail addresses and phone numbers. Surprisingly, these increases cannot necessarily be attributed to the 30 percent increase in mobile vulnerabilities. While Apple’s iOS had the most documented vulnerabilities, it only had one threat discovered during the same period. Android, by contrast, had fewer vulnerabilities but more threats than any other mobile operating system. Android’s market share, its open platform and the multiple distribution methods available to distribute malicious apps, make it the go-to platform for attackers.
In addition, 61 percent of malicious websites are actually legitimate websites that have been compromised and infected with malicious code. Business, technology and shopping websites were among the top five types of websites hosting infections. Symantec attributes this to unpatched vulnerabilities on legitimate websites. In years passed, these websites were often targeted to sell fake antivirus to unsuspecting consumers. However, ransomware, a particularly vicious attack method, is now emerging as the malware of choice because of its high profitability for attackers. In this scenario, attackers use poisoned websites to infect unsuspecting users and lock their machines, demanding a ransom in order to regain access. Another growing source of infections on websites is malvertisements—this is when criminals buy advertising space on legitimate websites and use it to hide their attack code.
