The report also reveals the most commonly used exploits, most prevalent malware families and more.
Key highlights from the 2016 Trustwave Global Security Report include:
- Weak application security: 97% of applications tested by Trustwave in 2015 had at least one vulnerability. 10% of the vulnerabilities discovered were rated as critical or high risk. The median number of vulnerabilities discovered per application by the Trustwave Managed Security Testing service was 14.
- Where security incidents occur: 35% of data breach investigations conducted by Trustwave occurred in North America, 21% were in the Asia-Pacific Region, 12% were in Europe, the Middle East and Africa and 10% were in Latin America and the Caribbean.
- Who criminals target: Retail was the most compromised industry, making up 23% of Trustwave investigations, followed by hospitality at 14% and food and beverage at 10%.
- Shift in compromised environments: Compromises affecting corporate and internal networks increased to 40% in 2015, up from 18% in 2014. 38% of investigations were of e-commerce breaches, compared to 42% in 2014. 22% were Point-Of-Sale (POS) breaches. POS compromises decreased 18 percentage points from 2014 to 2015, making up 40% of Trustwave investigations in 2014 and 33% in 2013.
- Magento is a target: 85% of compromised e-commerce systems used the Magento open-source platform. At least five critical Magento vulnerabilities were identified in 2015 and most of the affected systems were not fully updated with security patches.
- Data most targeted: In 60% of investigations, attackers were after payment card data, split about evenly between card track (magnetic stripe) data (31% of incidents), which came mainly from POS environments and Card-Not-Present (CNP) data (29%), which mostly came from e-commerce transactions.
- Self-detection of breaches: The majority of victims, 59%, did not detect breaches themselves. The report reveals that self-detection leads to quicker containment of a breach. Self-detection increased from 19% in 2014 to 41% in 2015. In 2015, for self-detected breaches, a median of 15 days elapsed from intrusion to containment. For breaches detected by an external party, a median of 168 days elapsed from intrusion to containment.
- Malvertising goes mainstream: The Trustwave analysis of the RIG exploit kit, the most prominent exploit kit of 2014 and the third most prominent in 2015, shows that approximately 90% of traffic to the kit originates from malicious advertisements. Even some of the largest ad networks have been misused by attackers to spread malware to unsuspecting users visiting popular websites.
- The Year of Angler: Angler, the most prevalent exploit kit of 2015, accounted for 40% of exploit kit-related incidents we observed, more than twice as many as the next most prevalent kit, Nuclear. Angler was also the first exploit kit to integrate several newly disclosed exploits, including four zero-day exploits and seven 'one-day' exploits, which target vulnerabilities for which patches have been released but have not yet been widely distributed.
- Shifting spam subjects: In 2014, pharmaceutical product spam made up almost three-quarters of the spam messages Trustwave analysed. In 2015, that portion dropped dramatically, to 39%, which was still enough to make it the largest share of any category. Spam related to online dating sites and adult products made a combined five-fold leap from 6% in 2014 to 30% in 2015. 5% of overall spam included a malicious attachment or link, a 1 point decrease from 2014.
Robert J. McCullen, Chief Executive Officer and President, Trustwave, commented: "Cybercriminals have been congregating and organizing for years, but 2015 showed a marked increase in the behaviour we would normally associate with legitimate businesses. Based on the study of numerous security incidents, exploit kits and malvertising campaigns, our 2016 Trustwave Global Security Report shows businesses how and where these sophisticated criminal organisations are most likely to attack and, more importantly, how to defend their assets."
Trustwave experts gathered real-world data from hundreds of breach investigations the company conducted in 2015 across 17 countries. This data was added to billions of security and compliance events logged each day across the global network of Trustwave Security Operations Centers, evaluation of tens of billions of email messages, analysis of tens of millions of web transactions, thousands of web application security scans and penetration tests, telemetry from security technologies distributed across the globe and industry-leading security research.
