Build Phishing Countermeasures to Protect Your Brand

Corporations fight phishing each and every day. Large and recognizable financial institutions, retail companies, internet service providers/telecommunication companies are among those most heavily targeted victims of phishing.

While the aftermath of a phishing attack is costly and yields long-term consequences, it’s quite difficult to keep up with cybercriminals. It’s shockingly easy for cybercriminals to create a phishing site targeted at your brand, so easy that the cybercriminal simply needs to unpack and upload a pre-built “phishing kit” in order to create a new phishing website. Just one phishing kit can produce hundreds of phishing URLs.

With just a few clicks of the mouse, the cybercriminal attacks your brand, sending you scrambling to “take down the site.” One-by-one you take down each individual website, costing your brand time, money and reputation. As you take down, he creates. It’s a never-ending battle. In our data, we’ve found that it is often the case that the same attacker is using this method to attack several institutions or companies within the same industry over a period of several months or years.

While the term “big data” is both ambiguous and overused, it defines the new frontier in the fight against phishing. Data sourced from hundreds of phishing sites targeting hundreds of brands is analyzed to identify trends, which allow us to build more effective strategies to fight cybercrime and prevent future phishing attacks.

Below we’ll discuss how to use phishing intelligence to build more effective countermeasures to protect your brand from attackers:

  1. Isolate a single attacker. Instead of taking down each phishing site one-by-one, what if you could go directly to the source and stop the criminal in his tracks? Analyzing phishing data allows us to gain clues as to how the criminal operates. For example, in a recent analysis of phishing attacks targeting large financial institutions, we found one particular criminal who had created 604 phishing sites with a single phishing kit, 390 of which were hosted on a single IP address. We call this a “clue.” Using this data, we’re able to identify several details about the criminal, often including email addresses and social media profiles. If you could identify an attacker that’s behind multiple attacks against your brand, how would that change the way that you approach phishing in your organization?
  2. Identify the monetization path. Another important component of building effective countermeasures against cyber attackers is to take a close look at the monetization path. It’s critical to understand the motives behind the attack (is the attacker money-motivated in the first place?) and how he has constructed his scheme to put your money in his pocket. Understanding the process is a key step in building future strategies and barriers to stop cybercriminals in their tracks.
  3. Build barriers. Using intelligence and patterns that you’ve identified, build barriers to protect your brand against future cyber attacks in order to identify threats early and stop criminals from leaving a stealing from your customers.

Defining a Sophisticated Attack

What do nearly all of the recent high-profile data breaches have in common? They have all been traced to sophisticated threats and cyber criminals. While there are many disagreements in the security industry, after every significant breach nearly everyone agrees that it was sophisticated (Twitter, Apple, and the Department of Energy are some of the unfortunate organizations to be compromised by a sophisticated attack recently).

On the surface, it isn’t hard to see why. First, technology vendors need attackers to be super sophisticated, because simple tactics couldn’t circumvent their products, right? For victims of a breach, it is advantageous for it to seem as though it took a sophisticated actor to penetrate its network. And from the incident response standpoint, it behooves IR consultants to describe these breaches as ultra-sophisticated to help their customers save face.

What Trend Micro’s research means for organizations

Trend Micro has just published research confirming what we at PhishMe already knew – spear phishing is the top threat to enterprise security. Trend Micro’s report estimates that spear phishing accounts for 91% of targeted attacks, making it the most prevalent method of introducing APT to corporate and government networks. Industry recognition of the severity of the dangers posed by spear phishing is always a positive development, but merely acknowledging the problem doesn’t provide a solution.

Fortunately, many of the underlying issues Trend Micro identifies are problems PhishMe is already helping our customers address.

Machines v/s Humans: Who Do You Think Is More Intelligent?

As the barrage of security breaches continues, Citigroup is the latest victim. This eWeek article: http://www.eweek.com/c/a/Security/Citigroup-Credit-Card-Portal-Breach-Compromises-200000-Customers-461930/ discusses the potential impact of this attack.   One of the commentators brings up the topic of phishing.   Hannigan, the CEO of Q1 labs, rightly points out that  “Security trust means more than just making sure you’re in compliance with regulations,”. On the other hand, some of the quotes, like that from Anup Ghosh, co-founder of Invincea has a blatant technology solution vendor bias. He discounts human intelligence when referring to customers in this quote – “it’s not reasonable to expect them to differentiate spear phishing attacks”. So technology can differentiate these attacks but humans can’t? The claim is baseless.

Having trained in excess of 1.8 million people using PhishMe, I can confidently say that training works! It’s how you train people that matters. Invincea has a solution to protect against malicious PDFs and one to isolate the browser to protect against malware, I guess. Even if we assume that they provide 100% protection in these domains, what about malicious files in other formats – .docx, .xlsx, .chm (and the list goes on)?  How long do you think it would take one of my Intrepidus Group consultants to craft an attachment that would squeak past Invincea’s solution? (hint: not very long)

What about targeted attacks that solicit sensitive information? Sweeping claims by vendors are a disservice to our industry. The false sense of security they create by offering a solution that relies on a single approach or technology do more harm than good. Their customers feel at ease and think that the targeted phishing problem is solved by that shiny box with blinky lights. There is no panacea – defending against spear phishing needs a multi-pronged approach – education/training, technology at the mail server, technology at the end point…and even then the bad guys may succeed; but you’ve raised the bar!
