Now more than ever, digital security is something that needs a thoughtful approach.

From Yahoo! to the DNC, large, high-profile security breaches are filling the news and making security a hot topic for everyday conversation. There are so many hacks that even data visualizers are struggling to make sense of them all. Which is why 2017 will be the year that companies finally realize the value and necessity of security for their digital properties.

Whether cause or effect, our increasing reliance on technology correlates with the spike in frequency, size, and severity of security breaches. At Sandstorm®, we're big fans of Steve Gibson and his podcast Security Now, where he talks about the race to keep up with new security threats. With each new security improvement developers release, hackers are ready to uncover weaknesses. Over the years, this has brought us to a place where both the threats—and the necessary defenses against those threats—have reached a level of complexity that can seem daunting.

From Convenience to Security

The complexity and automated nature of modern attacks has changed the industry’s view on the lengths hackers are willing to go to. Now, we have to assume that there is always someone looking to exploit opportunities and weaknesses.

While these are just a few examples of the risks and remediations that companies need to consider, they illustrate the many different attack vectors that developers need to address. The trick is to do the following:

  • Define the requirements
  • Identify the risks and determine the solutions
  • Design a highly functional application that still puts the user first

Trend #1: Rise of the Botnets

Botnets are a major reason for the increase in security issues. As an industry, we’ve known for some time about the danger of improperly patched or unsecure computers and servers that get infected with malware. But in the last few years, risk has increased exponentially due to the prominence of the Internet of Things (IOT). We have an explosion of internet-connected devices (light bulbs, refrigerators, dishwashers, teddy bears) with many of them rushed to market without regard for security.

Night of the Living Malware

Malware programs target these vulnerable systems to create zombie armies of infected computers that work together to feed on sites. The most recent and well known is the Murai botnet, the code of which was released as open source and has since spawned a plethora of derivations. That's right; you heard me. They’re multiplying, evolving, and getting smarter like a creature out of a bad horror movie.

How bad is it? Projections as of 2016 suggested that 35% of all internet traffic consisted of malicious bots. That's a lot of zombies wandering around looking for your server's brains.

GhostBot in the Machine

Another recent example is GiftGhostBot. This attack came to light in March 2017. Bots are brute forcing the pages that allow customers to check the balance on their gift cards. These bots keep guessing gift card numbers (at an estimated rate of four billion requests per hour) until they get one that has a remaining balance. They can then use that gift code to steal from the gift card holder.

What makes this GiftGhostBot particularly sinister is its sophistication. First, the attack is distributed across multiple compromised devices, servers, and computers—which means there’s no way to track and block these requests by IP. Second, the bots have been set up to use over 740 different user agent profiles, meaning they masquerade as different browsers and operating systems to confuse attempts to filter out their traffic. Vendors might add CAPTCHAs or completely remove these pages to remediate the issue. This is just another example of the exponential scale and complexity of attacks that have shifted the conversation towards security.

What You Can Do

  1. Your best defense is keeping your systems up-to-date. Apply security updates to all technology in your ecosystem in a timely manner (including websites, servers, computers, employee mobile devices, etc.).
  2. Be sure to spend the time to review all new features and components of your digital products with an eye for potential vulnerabilities. Always overestimate the lengths someone would go.
  3. When in doubt, engage a knowledgeable specialist to help review your security configuration.

Trend #2: Are You a Robot? – Identifying Friend From Foe

If you’re thinking this is all about the rise of the machines, you might (or might not) be happy to hear that humans still play an important role in threatening your business’s security. While botnets have increased the quantity of attacks, the level of sophistication for attacks has also dramatically increased. In some areas, malicious entrepreneurs have even turned to crowdsourcing to enhance automated attacks. Take CAPTCHA as an example. When those annoying pictures were too much for some bots to circumvent, unscrupulous companies paid real people to fill them out. Bots passed the CAPTCHAs back to humans whose answers were fed back to the bots so they could proceed with their attack.

Invisible ReCAPTCHA

This resulted in concerns with the CAPTCHA as a solution for determining bot from human. While still used, it was understood that this solution is not 100% effective. Recently, however, Google updated their reCAPTCHA service with their new Invisible reCAPTCHA. Maybe you’ve seen this: It’s a simple checkbox that says “I am not a robot.” Because so much information on your behavior has been compiled by Google, it can compare your digital fingerprints and activity against its vast repository of analytics to determine if you’re a real person. Or that’s the theory anyway; the new service has just rolled out and we're excited to see how it matures.

Mollom

Mollom is another service we recommend, specifically for Drupal projects. It takes form submissions on your site and checks the content to see if it looks like bot-generated content. If it does, the content is flagged. This technique analyzes content to protect against spam, relying on the consolidation of massive amounts of examples to understand how to proceed.

What You Can Do

  1. You can do is realize that identifying bots is not as straight-forward as it seems. They have gotten very good at pretending to look like real users performing real actions on your site.
  2. Shift your thinking to a place where you assume that hackers and spammers are probably smarter (or at least more persistent) than you. Look at each element of your digital products as a place where a bot might pretend to be a human and consider what they might be able to do.
  3. Layer different preventative techniques. Don't assume that one fix is enough and have a contingency plan for is a bot does get past your defenses.

Trend #3: Moving to SSL

Another major trend for 2017 will be the push for secure socket layer (SSL or HTTPS) traffic for everything. This has been an important shift for security in the last few years. Previously, SSL was only considered important for highly sensitive data, but a few things have pushed us into a world where regular HTTP traffic is considered unsecure.

Man in the Middle

First, a number of tools have come out that make watching the traffic of someone else on your network very easy to do. This allows a person to see the sites you are visiting and even steal your username and password. This is generally referred to as a man-in-the-middle attack resulting in session hijacking. Traffic over HTTPS helps to protect against that because your browser and the server are essentially communicating via a secret language that only they can understand.

Man on the Side

Second, browsers pulling in content over regular HTTP can't 100% confirm where the content they’re displaying came from. There have been a few complicated attacks over the past few years where malware was sent to site visitors instead of the assets they were expecting. This is generally referred to as a man-on-the-side attack. The attempted attack on GitHub in 2015 is an example of this. Moving towards HTTPS traffic gives the browser certainty that the content it received is the one it was expecting.

Pushing the Transition

If you’re thinking all of that sounds scary, you're not alone. Google agrees and has started to roll out changes to the Chrome browser—you've probably noticed that grayed out "not secure" message near the URL. Additionally, if you log in to a site over regular HTTP, you may also notice a red "not secure" message. This is meant to push websites towards SSL, and it’s only the start. Google has announced additional plans to clearly mark all traffic as not secure going forward.

What You Can Do

  1. Work with your hosting provider or website developer to purchase an SSL certificate from a reputable vendor.
  2. Have those same partners review your SSL configuration to confirm that you’re using strong protocols and ciphers that have not been deemed to be compromised.
  3. You may also need to review your site to confirm that you don't have any mixed content errors, which is when HTTPS pages are referencing insecure HTTP resources.
  4. While you're at it, complete a full review of your server configuration.
  5. A full penetration test or security scan may also be a good investment.
