Welcome to The Senroc Download! This is your weekly briefing from the team at Senroc Technologies letting you know what we're seeing, what we're thinking, and tips you can use right now.

Most businesses have adopted multi-factor authentication (MFA) — where you enter your password and then approve a notification on your phone. While MFA has become the standard for protection, many businesses don’t realize attackers are finding ways around it.

Here's what happens: an attacker gets hold of your employee's password through a breach of a vendor or through a phishing attack. They try to log in to your systems. Your employee's phone gets a notification that says "Did you just sign in?" The employee is in the middle of their day and taps Approve without realizing what they’ve done. The attacker is in.

This is called an MFA fatigue attack. Attackers will send dozens of these notifications — sometimes in the middle of the night — until someone approves one accidentally or because they don’t understand what it is.

Takeaway: Ask your IT team whether number matching is enabled on your Microsoft Authenticator or similar app. This is a five-minute fix that closes one of the most common attack paths we see with misconfigured MFA.

Most people's instinct when something weird happens on their computer is to keep clicking around to figure out what's going on. If your screen starts acting strange, a pop-up appears telling you to call a number, your files suddenly look encrypted, or your browser is doing things on its own — here's what to do before you do anything else.

First, disconnect from the internet. Pull the network cable out of the wall, or turn Wi-Fi off on the device. This cuts off the attacker's connection to your machine and stops data from leaving. Second, don't turn the computer off. It sounds counterintuitive, but some attacks hide evidence when a machine powers down. Leaving it on preserves what IT needs to investigate. Third, don't click anything else on the machine. Don't try to close windows, run a scan, or move files. You may be moving the problem around rather than stopping it. Fourth, call your IT provider immediately!

Takeaway: These four steps won't solve the problem, but they give your IT team the best possible chance to contain it before it spreads to other machines or takes your business offline. Share it with anyone in your office who uses a computer. The two minutes it takes to read this can save on recovery time.

For a long time, a cyberattack on a small business looked like someone casting a wide net — automated tools probing thousands of companies at once, looking for anything easy to exploit. Most of the time, it wasn't personal. It was volume.

That's changing. Security researchers are documenting a new approach where attackers use AI tools to map out a specific company before attacking it — your website, your job postings, your social media, public records, and even your email headers — to build a picture of what software you run, who your employees are, and where the likely weak points are. The attack that follows is more targeted, more convincing, and harder to catch.

A phishing email that references your actual software vendor by name is more likely to get clicked than a generic one. An attacker who knows your company uses a specific accounting platform can craft a fake login page for it. This is the direction things are moving.

The answer isn't to panic — it's to make sure your defenses aren't relying on attackers being unsophisticated. Email filtering, endpoint protection, and employee awareness training matter more now, not less.

Takeaway: The "we're too small to be targeted" assumption is getting less reliable every year. AI makes targeted attacks cheap enough to run against businesses of any size. If your security setup was built around the idea that attackers won't bother, it's worth a second look.
