Bromium Research Reveals Sophisticated Crypto-Ransomware Menace

CUPERTINO, CA--(Marketwired - Nov 19, 2014) - Bromium®, Inc., the pioneer and leader in transforming endpoint security using micro-virtualization, today announced the publication of "Understanding Crypto-ransomware," which analyzes the anatomy of an attack. The report dissects the sophisticated malware, which evades detection-based security solutions, such as antivirus, and leverages advanced encryption to encode enterprise file types until a ransom is paid, resulting in millions of dollars of losses.

"Crypto-ransomware is a particularly devious attack because of its potential to cause financial losses and irreparable damage to organizations that cannot access critical files," said Rahul Kashyap, chief security architect, Bromium. "Crypto-ransomware lacks the subtlety of Trojan attacks that evade detection during infection, openly flaunting its compromise and demanding payment since antivirus is unable to reverse the process."

"Understanding Crypto-ransomware" provides a comprehensive analysis for the most prevalent crypto-ransomware families uncovered in the wild. Bromium Labs reverse engineered each sample and executed it in a virtualized environment to observe its behavior. Key findings from "Understanding Crypto-ransomware" include:

• Crypto-ransomware Evolves to Target the Enterprise: Initially, crypto-ransomware focused on consumers, primarily targeting the sentimental value of image files. Over time, the number of file types targeted has increased nearly 200 percent, from 70 to 230, including a focus on business software file types.
• Crypto-ransomware Leverages Advanced Attack Techniques: Crypto-ransomware compromises are frequently caused by process injection, which may be delivered by malvertising. The process injection obfuscates code and covertly launches, rendering antivirus solutions ineffective.
• Anonymized Traffic and Payment Channels Hinder Investigation: Crypto-ransomware leverages encrypted traffic channels to communicate with command-and-control servers, shrouding their location. Payment is demanded in Bitcoin, which is less regulated and more anonymous than other currency.
• Advanced Encryption Techniques Stifle Code Crackers: Early crypto-ransomware flaws enabled researchers to reverse engineer a tool to recover files. As a result, crypto-ransomware has implemented advanced encryption algorithms that are nearly impossible to defeat.
