Arbor Releases New ASERT Threat Intelligence Report

Arbor Networks

Arbor Networks Inc., the security division of NETSCOUT, has released a new ASERT Threat Intelligence Report that reveals TTPs (tactics, techniques, procedures) of threat actors distributing the CryptFile2 ransomware threat to victims worldwide.

According to an interagency report from the U.S federal government titled ‘How to Protect Your Networks from Ransomware’, there have been 4,000 ransomware attacks per day in 2016, a 300-percent increase over the approximately 1,000 attacks per day seen in 2015. The report goes on to say, “Ransomware targets home users, business and government networks and can lead to temporary or permanent loss of sensitive or proprietary information, disruption to regular operations, financial losses incurred to restore systems and files, and potential harm to an organisation’s reputation.”

“Most analysis of ransomware activity tends to focus on endpoint malware activity, encryption method and in some cases, how to decrypt without paying a ransom. ASERT has delivered visibility into the threat from the server side which is far less common. This analysis provides unique insight and context to this malware family, and it is our hope that it can be used to improve situational awareness, inform detection capabilities and improve defensive posture with regards to ransomware staging and distribution,” said Curt Wilson, ASERT senior threat intelligence analyst.

In addition to the unique insight provided via Arbor’s ATLAS infrastructure, a collaborative project with more than 300 network operators who have agreed to share anonymous traffic data totalling 140Tbps (approximately one-third of all internet traffic), ASERT has extensive visibility into advanced threat actor and global malware activity. From this informed perspective, ASERT develops campaign oriented threat intelligence for customers, complete with the context and confidence information required to detect and stop specific threats, and continuously enhance security posture over time. When a new campaign or distributed denial-of-service (DDoS) attack vector is detected, an attack policy is created, distributed and installed in Arbor’s products via the ATLAS Intelligence Feed.

ASERT brings a diverse set of expertise, from Fortune 25 Computer Emergency Response Teams (CERTs) to former law enforcement, threat mitigation vendors and well-known malware research organisations. ASERT shares operationally viable intelligence with hundreds of international CERTs and with thousands of network operators via intelligence briefs like this one and security content feeds.
