# Cybersecurity for Panamanian SMBs: AI now finds (and exploits) vulnerabilities before you do > The Rejetto HFS case made it clear: an AI found a critical flaw and attackers are already exploiting it. What it means for your SMB and how to protect yourself without an internal security team. URL: https://pgtechcorp.com/en/cybersecurity-ai-smb-panama/ Actualizado: 2026-10-06 --- In October 2026 it became clear that cybersecurity has changed pace. An **AI discovered a critical flaw on its own** in a file server used by thousands of offices worldwide. And within a few days, attackers **were already exploiting it** against real companies. The case has a name: **Rejetto HFS**, a free, lightweight program for sharing files in offices. The flaw, catalogued as **CVE-2026-61500 with a severity of 9.3 out of 10**, lets an attacker take full control of the machine. What used to take weeks to appear is now discovered and exploited in days. Does that mean you need an in-house security team to protect your SMB? No. It means the time between «something is happening» and «it is already too late» has shortened — and protection can no longer be reactive. ## What happened: an AI found a flaw and attackers exploited it within days Rejetto HFS is a free file server for Windows that many small offices use to share documents among colleagues or with clients, without setting up complex infrastructure. That is exactly why it became a target. We cover it in detail in our article on [the critical Rejetto HFS flaw](/en/rejetto-hfs-critical-flaw-cve-2026-61500/). The flaw **CVE-2026-61500** is critical: HFS generated the administrator session identifier in a **predictable** way. An attacker could forge that session without a username or password and, once in as administrator, **execute code at will** on the machine (remote code execution). The detail that marks a shift in era: the vulnerability was **discovered by an AI** — the Mythos model from Anthropic, used by the Horizon3.ai team — on September 30. The proof of concept went public in late September, and by October 5 VulnCheck had already confirmed **active exploitation in the wild**. The fix is version **3.2.1**. ## The 2026 shift: AI accelerates both attacks and vulnerability discovery The news is not «another flaw appeared». It is that the whole cycle sped up in both directions: - **They are found faster:** AI reviews code and finds flaws at a speed a human team cannot match. - **They are exploited faster:** from discovery to exploitation no longer takes months, but days. And this is not an isolated case. In September, researchers used **Claude (Anthropic) to chain two vulnerabilities** and get into OpenAI accounts and an internal repository in under 72 hours. Google revealed that its **Gemini model accessed three real companies** during security tests. The point is not that AI turned bad. It is that the targeted attack — the one that used to require an expert team and weeks — is now **cheaper and faster**. And the favorite target is still the easiest one: the SMB without monitoring. ## Your real surface: file servers, email, remote access, and outdated patches To an attacker, your business is not «too small to matter». It is a target with **open doors**: old file servers, unprotected email, uncontrolled remote access, and **outdated patches**. Ransomware is still the number one threat, and **phishing the most common vector**: around **86% of SMBs** suffered some incident in the last year. And most found out **after the damage was already done**. The question worth asking today is not «will they attack me?», but «**would I know in real time if someone got in?**». Without monitoring, the answer is usually no.

What you need is a process that **keeps watching all the time** and acts before the problem reaches your customer. PG Tech’s [24/7 Security Monitoring (MPS)](/en/services/security-monitoring/) combines a **Spanish-speaking AI agent + human analysts**: it watches your devices, email, and access, applies patches on time, and alerts you to anything unusual. Plans from **$149.95/month**. It is the same shift as in health: you do not wait for a heart attack to get a checkup. In cybersecurity, neither should you. ## Frequently Asked Questions ### Do I need an in-house security team? No. 24/7 monitoring with an AI agent and analysts replaces what used to require an in-house team: continuous watching, up-to-date patches, and early alerts, at a fraction of the cost. ### Does it work if I am a small office? Yes, and that is where it shows the most. A small office is the attackers’ favorite target because it tends to run old tools with no monitoring. Starting with 24/7 monitoring protects you without hiring staff. ### What if I use HFS or another file server? If you use HFS, update to version 3.2.1 immediately. In general, a loose, exposed file server is a risk: the lasting fix is to move to a managed file solution with backup, access control, and monitoring. ### How much does it cost and how soon am I protected? 24/7 Security Monitoring starts at $149.95/month, and protection begins as soon as monitoring is connected to your devices.
