In another stark reminder of today’s rapidly evolving cyber threat landscape, a new report by GBHackers reveals that a threat actor successfully bypassed SentinelOne's Endpoint Detection and Response (EDR) system to deploy Babuk ransomware, encrypting critical data and holding it hostage for ransom.
This latest attack exemplifies a worrying trend: even advanced EDR solutions are being outmaneuvered by sophisticated adversaries. The attacker didn't just exploit a known vulnerability—they actively evaded the EDR platform, rendering traditional “detect and respond” tools ineffective.
Here’s what happened and why it demands a serious reevaluation of how businesses protect their endpoints.
According to the GBHackers report, the attacker gained access to the target system and manually uninstalled SentinelOne using an unprotected command line. With the EDR platform removed, they executed the Babuk ransomware, which proceeded to encrypt files and extort the victim.
This wasn’t a zero-day exploit or some magical piece of malware. It was a calculated bypass that exploited the limitations of software reliant on detection and behavioral analysis. Once the EDR was gone, nothing stood in the way of the attack.
This is not just a failure of a single product—it’s a broader failure of a defensive paradigm that assumes threats can always be detected and neutralized after infiltration begins.
Most cybersecurity solutions today fall under the umbrella of "detect and respond." This model assumes that if you monitor behavior closely enough and respond quickly enough, you can stop malicious actors before they do damage.
But this incident (and many others like it) highlights the weakness of that assumption. Detection can be avoided. Responses can be delayed or disabled. Sophisticated attackers plan for these scenarios.
The SentinelOne bypass is not an isolated event—it’s part of a growing pattern. Ransomware gangs, state-backed hackers, and cybercriminal syndicates are becoming more adept at:
Disabling or uninstalling EDR/AV tools
Using legitimate administrative tools to hide malicious behavior
Deploying payloads that don’t trigger detection engines
So what’s the alternative?
It’s time for businesses to shift their mindset from Detect and Respond to Isolation and Containment.
Instead of relying on a reactive model, AppGuard uses a prevention-first approach. It doesn’t wait to identify malware or suspicious behavior. Instead, it enforces strict containment rules that prevent unauthorized processes—including ransomware—from executing in the first place.
Here’s how AppGuard makes a difference:
No Signatures, No Scanning: It doesn’t rely on outdated definitions or machine learning guesses. It enforces policy at the kernel level.
Stops Attacks Before Execution: Malicious code—even if unknown—is stopped from launching, sidestepping the need for “detection.”
Tamper-Resistant: AppGuard is engineered to prevent unauthorized removal or disabling, addressing the exact vulnerability exploited in the Babuk ransomware incident.
10-Year Proven Track Record: It’s not a beta product or a theoretical solution. AppGuard has a decade-long history of stopping advanced attacks in high-security environments—and it’s now commercially available.
The attackers behind this recent incident didn’t need a zero-day. They didn’t break encryption or invent a novel exploit. They simply used known tactics against a well-known EDR—and succeeded.
How many other businesses are exposed in the same way?
If you're relying solely on “detect and respond” tools, your defenses are already outdated. Modern threats are faster, stealthier, and increasingly built to exploit the lag time between detection and response.
AppGuard neutralizes that lag.
At CHIPS, we’re helping business owners take proactive steps to defend against ransomware and other advanced threats—not with more alerts and dashboards, but with real prevention.
Let’s talk about how AppGuard can protect your business.
If this attack sounds uncomfortably familiar—or if you’ve been lucky enough to avoid it so far—don’t wait until you're the next headline. Reach out to CHIPS today and discover how AppGuard’s isolation and containment model can stop threats before they start.
It’s time to stop detecting and start preventing. AppGuard is the answer.
