Biggest Cyber Trend in 2022

You Can’t Fix Stupid

By Guy Rosefelt, CPO, Sangfor Technologies

Stop me if you have heard this one: a customer is working late at night, been a long day, and very tired. Customer needs to clear a few remaining emails including one from the CEO. Without thinking about it, customer opens the email from the CEO, barely skims it and opens the attached Word document. Just as the Word doc opens, customer realizes the email looks a bit odd and then it hits, it is a phishing email. Laptop infected.

Sound familiar? That just happened to my customer yesterday. And he knows better but was tired and on autopilot. We spent an hour online trying to figure out how bad the infection was and if he should wipe out his system and reimage since he had just done a full backup the week before. We decided to err on the side of caution and wipe and restore.

The moral of the story is anti-phishing will never be 100% successful. The best security products are only ninety-nine point something successful, but even at that rate with the number of emails received in an organization daily, a few are going to get through. And someone will click on one. My customer is normally very diligent, but he slipped. Worse, there are a few employees in every company that do not really check to see if emails are suspicious and will open them anyway.

Why am I rehashing this old trope? Because Barracuda Networks reported a 521% increase in phishing emails using COVID-19 Omicron variant to entice victims between October 2021 and January 2022. People looking for home testing kits were prime targets and easy prey. Webroot reported a 440% increase in May 2021. And more will keep coming.

“So, Guy,” you may ask, “how can you save us from phishing?”  Well, I cannot, and no one else can either. What we need to do is bite the bullet and shift our strategy from trying to block everything to assuming we are already compromised, breached, hacked, etc. Once you start from that viewpoint, it does not matter that you cannot fix stupid, you just have to deal with the aftermath. Your focus is now on threat hunting, looking for signs of compromise. Do you have tools that can watch low and slow network behavior that are indications of stealth scanning? Can you identify regular bursty encrypted traffic being sent someplace out on the internet that might be data being exfiltrated? Can you track system resource utilization for signs of cryptomining or other malicious behavior?

What makes looking for these kinds of behavior difficult is they are all AI-based. That’s right, attackers have learned to weaponize artificial intelligence (AI) into advanced persistent threats (APTs) and other malware payloads. The malicious software installed has become so much smarter than you think. It will look for specific targets, domains, even countries before it decides to activate. It can hide inside legitimate processes running in memory, evading security scans. In fact, it can disable security software running on systems without you knowing about it.

There is a powerful batch script available now called Defeat-Defender that can shut down all Windows Defender processes silently. The best part is Defeat-Defender can masquerade as a legitimate process, evading the new Windows Tamper Protection functionality. All from opening an infected Word document.

I see heads shaking in despair and a few of you getting ready to jump out of your office windows (you realize some of you work in the basement…). But there is a strategy that can help you through this dark and difficult time. You need to do 4 extremely simple and painless things:

Biggest Cyber Trend in 2022

  1. Look for and minimize attack surfaces

Conduct external and internal attack surface assessments to find ways for the attack malware to breach. Look for signs that those surfaces were exploited. Then work to close those holes.

  1. Deploy AI-based detection and response

You need to use AI to combat AI, but not just any AI. Security tools that employ broad-based AI will not find the signs of stealthy activity or APTs. Purpose-built AI models designed to identify very specific behaviors are needed, such as looking for enormous amounts of abnormal DNS requests going to malicious domains or finding short periods of bursty HTTPs traffic during off hours; both are indications of data exfiltration.

  1. Improve security system synergy

All security products have a sphere of influence covering their own security domain. But the domains do not overlap causing gaps that AI-enabled APTs can exploit. Having security products share data real-time and coordinate responses can close those gaps.

  1. Augment security operations and resources by using security services

Face it, you do not have enough time, staff, or resources to go into threat hunting mode. And if you are breached and under attack, can you really do incident response (IR)? Even the security teams in the largest organizations are resource limited. Leverage your VAR or security vendor to provide resources to backfill your team, help conduct assessments and IR, and do managed detection and response. Think of it as a home security monitoring service available 24 hours a day; that is there when the breach occurs during off-hours.

It isn’t possible to block everything 100% and combating stupid makes it even harder. Since you can’t fix stupid, these 4 things can minimize and contain the damage caused. More importantly, thinking like an attacker will help you find signs if you were attacked and close off any holes and vulnerabilities that attackers will use.
