Summer of Ransomware, Part 2?
May 23, 2023
Fortalice Solutions

Summer of 2020 was coined the "Summer of Ransomware", but are we about to have a second summer of ransomware in 2023? Fortalice Solutions has seen a significant increase in ransomware cases over the last three weeks. But we aren’t alone in this assessment. Our finding mirrors what our partners at various “three-letter agencies” across the the Federal Government are telling us that they are monitoring, as well. Specifically, we are seeing threat actors target health care providers in the United States with attacks ranging from data extortion to complete encryption.

Need more proof? Let’s go to the source: the hackers themselves. Fortalice recently reviewed the Karakurt Hacking Team’s website. The review indicated that healthcare providers are indeed being increasingly targeted. In fact, 70 percent of Karakurt’s named victims hail from the healthcare industry.

More troubling, the hacking team’s website hints that there will be more leaks this summer.

Many of this group’s tactics come straight out of the “Threat Actor 101 Playbook,” including leveraging vulnerable remote access servers and entry points as footholds into an environment. The lessons we can take away from Karakurt can easily be applied to similar established and up and coming criminal syndicates.

For example, Many of the Karakurt attacks can be traced back to a vulnerable technology on client perimeters. Karakurt and other bad actors tend to target an organization’s Human Resource (HR) data (e.g., Social Security Numbers, financial documents). The Karakurt Team is very skilled at data exfiltration. In fact, Karakurt team members have been known to reach out to employees to harass the victim organization.

Proactive Steps

So, what can you do to keep yourself, your organization, and its precious data safe, secure, and out of the hands of adversaries like the Karakurt hacking team? To start, it’s important to understand that the protections you need to prevent a ransomware attack by Karakurt are, for the most part, the same protections you will need against any other cyber-crime syndicates.

1. Understand your perimeter devices.

It is estimated that more than a third of all ransomware attacks begin by compromising a vulnerable asset (e.g., unpatched devices, legacy technologies, misconfigured servers) on an organization’s externally facing network. Scanning you external perimeter at a regular cadence can identify vulnerable assets.

2. Institute Regular Cybersecurity Awareness Training.

Business email compromise (BEC) accounts for another third of ransomware incidents. Ensuring employees are trained in good cyber hygiene can help insulate your organization.

3. Update your Incident Response Planning Capabilities.

Having an incident response (IR) plan is a critical step in preparing to weather an adversary’s attack. That said, having a plan is just the first step. Remember, it is important to exercise the plan. Consider facilitating a cybersecurity tabletop exercise (TTX) to uncover any gaps in your processes and procedures.

4. Evaluate your backup and restoration program.

It’s been said that “amateurs backup but professionals restore.” Isolating (and air-gapping where possible) your backups and having a well-documented process for restoration is the best way to ensure you can recover from a devastating attack. Having recovery time objectives (RTOs) for each of your business-critical applications will be necessary to develop your plan.
