Three Key Considerations When Evaluating Threat Intelligence Solutions

To address today’s evolving threat landscape, there’s been a shift from traditional event-driven security to intelligence-led security. Threat intelligence plays an integral role in this shift.

When you hear the term “Threat Intelligence,” it’s easy to have preconceived notions of what it means. Gartner defines threat intelligence as “evidence-based knowledge, including context, mechanisms, indicators, implications and actionable advice, about an existing or emerging menace or hazard to assets that can be used to inform decisions regarding the subject’s response to that menace or hazard.” I like that Gartner’s definition does not include intent. Why? Intent implies that the “menace” is trying to target you, but we know that too often this isn’t the case. Pretty much any piece of malware out there will damage unintended targets. One example is Stuxnet. It targeted Iranian nuclear enrichment facilities. Unfortunately it escaped the purported air-gapped system and has been seen in at least 10 other countries. In more practical terms threat intelligence must be:

  • Tactical
  • Contextual
  • Automated

NAB 2015 Attendees: Is Your Security Model Threat-Centric?

Cyber-Security: it has always been important for video entertainment companies. But times have changed- now it’s mission critical. Top of mind again this last few days, the events of the last 6 months have proven this point. If cyber-protection is not bullet-proof, any video entertainment company is living on borrowed time… and that bill is going to come due with potentially disastrous consequences.

There is a second change going on: security at video entertainment companies used to focus on protecting content in the distribution chain – DRM, CAS and the like. But there are many more ways to lose content – many more places in the “connected” production chain where content can be stolen. For instance, as has happened in the last few months, if an attacker can gain access to Read More »

Threat Spotlight: Dyre/Dyreza: An Analysis to Discover the DGA

This post was authored by Alex Chiu & Angel Villegas.

Overview

Banking and sensitive financial information is a highly coveted target for attackers because of the high value and obvious financial implications.  In the past year, a large amount of attention has been centered on Point of Sale (PoS) malware due to its major role in the compromise of several retailers.  While PoS malware is a major concern, attackers have also realized that targeting individual end users is an effective method of harvesting other types of financial data.  As a result, banking malware has become a prevalent category of malware that poses a major threat to users and organizations of all sizes.  One of the more well known examples of banking malware is Zeus.

Banking malware typically operates by redirecting users to malicious phishing sites where victim’s input their banking credentials thinking they are logging into their bank’s website.  Banking malware can also operate more stealthily by hooking into a browser’s functionality, capturing the victim’s credentials as they are typed in, and exfiltrating them.  Once an attacker has a victim’s banking credentials, attackers can then sell it or use it to perform illicit transactions (such as transferring funds to another account on behalf of the victim).

Dridex Attacks Target Corporate Accounting

In February, Cisco Managed Threat Defense (MTD) security investigators detected a rash of Dridex credential-stealing malware delivered via Microsoft Office macros. It’s effective, and the lures appear targeted at those responsible for handling purchase orders and invoices. Here’s a breakdown of the types of emails we’ve observed phishing employees and inserting trojans into user devices.

Equation Coverage

Cisco Talos is aware of the public discourse surrounding the malware family dubbed “The Equation Family”. As of February 17th the following rules (33543 – 33546 MALWARE-CNC Win.Trojan.Equation) were released to detect the Equation Family traffic. These rules may be found in the Cisco FireSIGHT Management Console (Defense Center), or in the Subscriber Ruleset on Snort.org. Talos security researchers have also added the associated IPs, Domains, URLs, and hashes to all Cisco security devices to provide immediate protection across the network. Talos will continue to monitor public information as well as continue to independently research to provide coverage to this malware family.

Advanced Malware Protection (AMP) is ideally suited to prevent the execution of the malware used by these threat actors.

CWS or WSA web scanning prevents access to malicious websites and detects malware used in these attacks.

The Network Security protection of IPS and NGFW have up-to-date signatures to detect malicious network activity by threat actors.

While email has not been observed as an attack vector, ESA is capable of blocking the malware used in this campaign.
