A King’s Ransom: Why Ransomware is Winning and How We Can Turn the Tide
by Michael Sutton of Zscaler

Abstract

Ransomware has exploded to become one of the most profitable tools in the attacker’s toolkit. Why? While ransomware has actually been around for more than two decades, the financial success of CryptoLocker, along with the emergence of anonymous payment schemes led to it’s resurgence in 2013. While Operation T

ovar killed off CryptoLocker, this only spawned a variety of copycat malware families following a similar pattern of leveraging public key encryption to hold personal files hostage until a ransom is ultimately paid. Attackers have managed to hit a sweet spot by targeting valuable data with financial or sentimental value, while setting a price point that individuals and corporations seem willing to pay. This, combined with poor data backup practices and ineffective endpoint security, has made ransomware a lucrative and growing market. As attackers have realized the potential of this weapon, they have moved beyond opportunistic attacks to target corporations and are now demanding significant payments well beyond the ransom demanded from individuals…and the companies are paying.

Combating ransomware requires a combination of dynamic analysis of the quickly morphing binary payloads and associated network traffic and exploiting the mistakes that have been made by the malware authors. Monitoring ransomware families over the years, we have noted interesting trends both in the techniques utilized by the families tracked and also where they are achieving success. Despite being generic in nature, certain malware families have reaped greater damage in specific global regions. The reasons for this involve a combination of attack techniques and hu

man psychology. In monitoring the impact of ransomware on over 5,000 enterprises, we have also noted unintended, but predictable behaviors that can aid in identifying and defending against the threat. Our research has shown that binary analysis of ransomware is only half the battle. An effective defense must also incorporate network traffic analysis to proactively identify the infrastructure used to facilitate the cycle of infection and extortion.

In this talk, we will address the evolution of ransomware and focus on specific case studies to demonstrate and reveal the unique traits leveraged by specific families. We will discuss solutions which have proven highly effective in combatting ransomware. We will also peer into the crystal ball and leverage the expertise that we’ve gained in observing thousands of ransomware variants to predict where this threat is headed next.
