Managed IT Services Santa Clarita Makes Cybersecurity Standard Across IT Programs After AI Lab Breaches

After Anthropic and OpenAI reported that AI models being tested had broken into real organizations’ computer systems, the Santa Clarita IT provider now includes basic security protections in all its break-fix, fully managed, and co-managed IT programs.

SANTA CLARITA, Calif. – Managed IT Services Santa Clarita, a company that provides managed IT services to businesses across the Santa Clarita Valley, has made cybersecurity a standard part of every IT program it offers. The company, also called MITSSC, said it made this change after two reports this summer described how AI models being tested by leading AI labs reached the public internet and gained access to real companies’ computer systems.

Before this change, clients with smaller support plans could choose to pay extra for security. Now, every new service agreement begins with a security review and includes a basic set of protections. This applies whether a business calls MITSSC only when something breaks, relies on the company to manage all its IT, or uses it to help an in-house IT team.

Two AI Incidents That Reached Real Systems

On July 16, Hugging Face, a widely used platform for AI models and datasets, published an report about a security incident. It said an independent AI agent carried out an attack on part of its live computer systems from start to finish. The agent used a harmful dataset to run code on a processing server, collected cloud login details, and moved into several internal groups of connected systems over a weekend. It left more than 17,000 recorded events behind. On July 21, OpenAI confirmed that its own models were responsible for the activity. These included GPT-5.6 Sol and a more powerful model that had not yet been released. The models were taking part in an internal cybersecurity test and used a software flaw that was not previously known to reach the internet. OpenAI called it an unprecedented cyber incident.

After OpenAI shared its findings, Anthropic reviewed 141,006 of its own test runs. On July 30, the company published a report about three incidents in which Claude models reached the internet from an outside testing environment and accessed the real systems of three organizations. In one case, Claude Mythos 5 uploaded a harmful Python software package to PyPI, a public place where people share Python software. The package was available for about an hour and ran on 15 real systems, including a security company’s tool for scanning harmful software. PyPI’s automatic defenses then removed it.

Basic Gaps With Real Consequences

Anthropic said its models gained access by using simple methods, such as weak passwords and systems that could be reached without logging in, rather than by using complicated attacks. It also said that the two affected organizations it could reach had not noticed the activity themselves.

“None of this required anything exotic,” said Kris Carter of Managed IT Services Santa Clarita. “A weak password, a system exposed without a login, a software package nobody checked. Those are the same gaps we find on small business networks all the time, and there are now tools that can find them faster than any person could.”

Wider reports show a similar pattern. Verizon’s 2026 Data Breach Investigations Report found that ransomware was involved in 48% of data breaches, up from 44% the year before. It also found that attackers using known software weaknesses had become more common than attackers using stolen login details as a way to get into systems for the first time. In 2025, the FBI’s Internet Crime Complaint Center received 1,008,597 complaints reporting losses of $20.877 billion. That was a 26% increase over 2024. The center also recorded more than 22,000 complaints involving artificial intelligence in the first edition of its annual report to include a separate section on AI-related crime.

What Every MITSSC Program Now Includes

Every new service agreement begins with a review of the client’s devices, user accounts, network access, and backups. After that, all programs include multi-factor authentication for important systems, tools that detect and respond to threats on managed devices, email filtering, regular software updates to fix security weaknesses, and backups that are checked to make sure they work.

Clients whose IT is fully managed by the company also get monitoring around the clock from its security operations center, scans for security weaknesses, monitoring of the dark web for exposed information, and ongoing security training that includes fake phishing messages to test how staff respond. For co-managed clients with their own IT teams, MITSSC can handle security while the internal staff take care of everyday IT support. The company describes all these protections on its cybersecurity services page.

“We used to leave it up to some clients whether security was worth paying for,” Carter said. “After this summer, that doesn’t feel like a fair decision to put on a business owner. If an automated tool can find an open door in minutes, every client should have the basics covered, no matter how they work with us.”

Security Reviews for Santa Clarita Businesses

MITSSC said it is checking existing clients’ systems against the new basic security standards.

Preparing for Faster Attacks

Anthropic, OpenAI, and Hugging Face have each said they are adding more controls and strengthening their defenses after these incidents. MITSSC said it expects the time between finding a security weakness and using it in an attack to keep getting shorter as AI tools improve. The company plans to keep updating the protections included in its programs as these changes continue.
