AMP Threat Grid Integrated with Email Security

We recently announced the release of AsyncOS 9.5 for Cisco Email Security that included the integration of AMP Threat Grid. Now if Threat Grid could talk it would sound a lot like Ron Burgundy and say “I’m not sure if you know this, but I’m kind of a big deal.” Email is consistently one of the top two threat vectors for malware because so many people out there still open an attachment that looks harmless from someone they don’t know. We all want to think we won a cruise, but that’s not how it works. It’s how malware establishes a foothold on your system. AMP Threat Grid is there to make sure this doesn’t happen.

Cisco acquired Threat Grid to not only bolster its suite of advanced threat solutions, but to also integrate the technology into its advanced malware protection (AMP) products. AMP Threat Grid goes far beyond traditional sandboxing, providing a host of analytical engines to evaluate potential malware. From static and dynamic analysis to various post-processing techniques, AMP Threat Grid evaluates malware to provide the most comprehensive report for even the most junior security analysts. This video provides a more comprehensive overview. Those familiar with Cisco’s Email Security know we already had a sandbox built in and may ask ‘Why change?’ and that’s exactly the question you want to ask. There are really three key reasons: Read More »

Ding! Your RAT has been delivered

This post was authored by Nick Biasini

Talos is constantly observing malicious spam campaigns delivering various different types of payloads. Common payloads include things like Dridex, Upatre, and various versions of Ransomware. One less common payload that Talos analyzes periodically are Remote Access Trojans or RATs. A recently observed spam campaign was using freeware remote access trojan DarkKomet (a.k.a DarkComet). This isn’t a novel approach since threat actors have been leveraging tools like DarkKomet or Hawkeye keylogger for quite sometime.

Some interesting techniques in this campaign were used by the threat actor to bypass simplistic sandbox methods including use of sub folders, right to left override, and excessive process creation. This threat also had surprising longevity and ample variations, used over time, to help ensure the success of the attack.

Vulnerability Spotlight: Apple Quicktime Corrupt stbl Atom Remote Code Execution

This post was authored by Rich Johnson, William Largent, and Ryan Pentney. Earl Carter contributed to this post.

Cisco Talos, in conjunction with Apple’s security advisory issued on June 30th,  is disclosing the discovery of a remote code execution vulnerability within Apple Quicktime. This vulnerability was initially discovered by the Talos Vulnerability Research & Development Team and reported in accordance with responsible disclosure policies to Apple.

There is a remote code execution vulnerability in Apple Quicktime (TALOS-2015-0018/CVE-2015-3667). An attacker who can control the data inside an stbl atom in a .MOV file can cause an undersized allocation which can lead to an out-of-bounds read. An attacker can use this to create a use-after-free scenario that could lead to remote code execution.

There is a function within QuickTime (QuickTimeMPEG4!0x147f0) which is responsible for processing the data in an hdlr atom. There is a 16-byte memory region, allocated near the beginning of the function, if the hdlr subtype field in an mdia atom is set to ‘vide’, this reference is passed to a set of two functions.

AMP Threat Grid integrates with Tripwire Enterprise

Today’s threat landscape is completely different than last year; and next years will be, not surprisingly, even worse. The Industrialization of Hacking has spawned a new era of professional, entrepreneurial, and resourceful cyber criminals. In recent year’s dynamic malware analysis (aka sandboxing) has become the shiny new technology that we all want, no, need to have. At one time anti-virus held this position as well, and the same will eventually be said of sandbox technology used to fight advanced malware.

You may have purchased a sandbox a few years ago but it’s likely that your malware analysis needs have gone beyond the traditional sandboxing technologies that simply extract suspicious samples, analyze in a local virtual machine, and quarantine. You need a more robust malware analysis tool that fits into your infrastructure and can continuously detect even the most advanced threats that are environmentally aware and can evade detection.

Tripwire recently partnered with Cisco and integrated the AMP Threat Grid dynamic malware analysis solutions into Tripwire Enterprise. But why choose this dynamic malware analysis tool? After careful evaluation there were a few key reasons to integrate this tool versus others:

  1. It’s not just dynamic malware analysis

    AMP Threat Grid provides both static and dynamic malware analysis, and a full subscription provides an API that is used to seamlessly deliver context rich threat intelligence into existing security technologies.

  2. Not everyone out there is a security expert

    Heck, very few are. AMP Threat Grid was designed to empower junior security analysts by providing a Threat Score so they can easily determine how malicious a sample is. The behavioral indicators are written in plain English so they can understand what the file is doing, and why its behavior is malicious, suspicious, or benign.

  3. Lack of instrumentation

    AMP Threat Grid was designed without any instrumentation inside the virtual machine. Most experts agree that around 40% of today’s malware is environment aware, checking to see if it is running in a sandbox or the age of the operating system before detonating.

There are 3 ways that most people deploy a malware analysis tool:

  1. A stand-alone solution designed to feed itself samples for analysis without dependency on other security products. This has the most flexibility in deployment but adds significant hardware costs and complexity to management and analysis, especially for distributed enterprises.
  2. A distributed feeding sensor approach, such as firewalls, IPS, or UTMs with built-in sandboxing capabilities. These solutions are usually cost effective and easy to deploy but are less effective in detecting a broad range of suspicious files including web files. They can also introduce bandwidth limitations that can hamper network performance and privacy concerns when a cloud-based solution is the only option.
  3. Built into secure content gateways, such as web or email gateways. This approach is also cost effective but focuses on web and email channels only and also introduces performance limitations and privacy concerns.

Since Tripwire is already monitoring and collecting the data on your mission critical systems, these approaches don’t seem to work. But there’s a fourth way that actually takes the best of what these approaches offer and raises the bar to help you fight well-funded attackers that get better at what they do every day: Cisco AMP Threat Grid. Through AMP Threat Grid, Cisco offers advanced malware analysis and intelligence that delivers integration directly with Tripwire Enterprise providing you with a better ROI and more visibility into what is happening in your environment. Tripwire has integrated AMP Threat Grid into their Tripwire Enterprise, providing both static and dynamic analysis so you can better understand the malware targeting your organization, as well as the ability to automate the consumption of threat intelligence into your existing security infrastructure.

How does the Integration actually work?

AMP Threat Grid’s content driven security analytics dynamically and statically analyzes all submitted files, executing the sample in a safe environment, examining the behavior of the samples, and correlating the results with hundreds of millions of other analyzed malware artifacts. In less than 10 minutes AMP Threat Grid reports back and Tripwire Enterprise tags the file with the result. This enables Tripwire Enterprise customers to prioritize actions for changes on systems with threats identified by AMP Threat Grid and initiate workflow actions for quick remediation.

Not only does AMP Threat Grid analyze a broad range of objects, but those interested in an AMP Threat Grid subscription will also be provided with deep analytics capabilities wrapped with robust context. With over 350 behavioral indicators and a malware knowledge base sourced from around the globe, AMP Threat Grid provides more accurate, context rich analytics into malware than ever before.
