The Value of Threat Intelligence

Cyber security is an ongoing battle between sophisticated and well-funded bad actors and those who must defend corporate networks against their attacks. The bad news is that the latter are typically not winning. A recent Osterman Research survey found that while most organizations self-report that they are doing “well” or “very well” against ransomware, other types of malware infections, and thwarting account takeovers because of the significant emphasis placed on these threats, they are not doing well against just about every other type of threat. These include protecting data sought by attackers, preventing users from reaching malicious sites after they respond to a phishing message, eliminating business email compromise (BEC) attacks, eliminating phishing attempts before they reach end users, and preventing infections on mobile devices.

This missing component for most organizations is the addition of robust and actionable threat intelligence to their existing security defenses, which can be segmented into four subcategories:

  1. Strategic (non-technical information about an organization’s threat landscape)
  2. Tactical (details of threat actors’ tactics, techniques and procedures)
  3. Operational (actionable information about specific, incoming attacks)
  4. Technical (technical threat indicators, e.g., malware hashes)

The use of good threat intelligence can enable security analysts, threat researchers and others to gain the upper hand in dealing with cyber criminals by giving them the information they need to better understand current and past attacks, and it can give them the tools they need to predict and thwart future attacks. Moreover, good threat intelligence can bolster existing security defenses like SIEMs and firewalls and make them more effective against attacks. Threat intelligence plays a key role in proactive defense to ensure that all security programs are relevant to the fast-evolving threat landscape. This is particularly valuable in security awareness training to ensure users are familiar with known threats.

Existing security defenses provide some measure of protection against increasingly sophisticated threats, but the enormous number of data breaches and related problems experienced by many organizations reveals that current security practices are not adequate. Good threat intelligence capabilities can provide a great deal of information about the domains and IP addresses that are attempting to gain access to a network. It can enable threat researchers to better understand the source of current and past attacks and better deal with future attacks.

Phishing and Ransomware are the Logical Evolution of Cybercrime

Phishing, which can be considered the delivery mechanism for various types of malware and cybercrime attempts; and ransomware, which is a specialized form of malware that is designed for the sole purpose of extorting money from victims, are critical problems that every organization must address and through a variety of means: user education, security solutions, vulnerability analysis, threat intelligence, good backup processes, and even common sense. The good news is that there is much that organizations can do to protect themselves, their data, their employees and their customers.

Phishing, particularly highly targeted forms of phishing like spearphishing and CEO Fraud/Business Email Compromise (BEC), as well as ransomware, are the logical evolution of cybercrime. Because there have been so many data breaches over the past few years that have resulted in the theft of hundreds of millions of records, there is a glut of this information on the market. The result, as there would be in any other business driven by the economics of supply and demand, is that prices for stolen records are dropping precipitously: a leading security firm estimates that the price of a stolen payment-card record has decreased from $25 in 2011 to just $6 in 2016.

Consequently, cybercriminals are turning increasingly to more direct means of theft. For example, ransomware will extort money directly from victims without requiring stolen data to be sold on the open market where it is subject to economic forces that can reduce its value. CEO Fraud/BEC can net hundreds of thousands or millions of dollars in a short period of time by getting victims to wire funds directly.

We are in the process of writing a white paper on phishing and ransomware, and will be publishing the results of an in-depth survey on these problems. Let us know if you have any questions or would like copy of the white paper when it is published next week.
