In late June 2025, security researchers uncovered a sophisticated supply chain attack targeting ConnectWise’s ScreenConnect platform. Threat actors abused a technique known as Authenticode stuffing to disguise malware as a trusted, digitally signed component of a widely used IT tool.
While many organizations are only now scrambling to assess their exposure, Aldridge clients were already protected—because we identified the threat early and acted swiftly, days before the exploit became public knowledge.
What Is a Supply Chain Attack?
A supply chain attack targets the software or tools that businesses trust—rather than going after the business directly. In this case, attackers compromised the integrity of ScreenConnect, a remote access tool that many IT providers (including some MSPs) rely on for day-to-day support.
By embedding malicious code into what appeared to be a legitimate, signed ScreenConnect file, attackers gained the ability to bypass antivirus tools, establish remote access, and steal sensitive data—all without setting off typical security alerts. This kind of attack is especially dangerous because it abuses the trust placed in essential IT infrastructure.
The Threat:
The exploit, now confirmed by multiple cybersecurity sources, allowed attackers to embed malware into what appeared to be a trusted, digitally signed file. According to Bleeping Computer, attackers used modified ScreenConnect payloads to slip past antivirus and EDR tools by exploiting trust in signed code. Once deployed, these files opened the door for remote access trojans (RATs), password theft, and long-term persistence.

How Aldridge Responded:
The difference between reacting and responding with purpose comes down to operational maturity—and that’s where Aldridge stands apart.
Our cybersecurity and operations teams were already monitoring unusual ConnectWise behavior patterns across client environments in early June. Within hours of internal confirmation, we:
- Deployed targeted threat-hunting queries across client environments
- Disabled and quarantined suspicious payloads before they could activate
- Confirmed EDR and firewall containment rules were actively blocking known indicators of compromise
- Updated client policies and detection rules to prevent future variations of this exploit
- Communicated transparently with clients, explaining the threat and how it was mitigated
Why This Matters:
Anyone can claim to offer cybersecurity tools—but true protection requires the right people, proven processes, and strategic tools working together. This incident is a prime example of why organizations need more than just software; they need a mature partner that understands the threat landscape and takes action before a crisis unfolds.
Why Aldridge:
At Aldridge, cybersecurity isn’t a checkbox—it’s embedded in every layer of our managed services. Our security-first mindset, paired with robust monitoring and rapid response capabilities, enables us to stay ahead of threats, not just react to them.
When you choose Aldridge, you’re choosing a partner who will:
- Stay informed of emerging risks
- Act before you even know there’s a problem
- Communicate clearly and confidently during any cybersecurity event
- Continuously refine and improve defenses as threats evolve
The ConnectWise exploit serves as a reminder that security is not just a product—it’s a partnership. With Aldridge, that partnership means confidence, clarity, and protection you can count on.
