Tech support scams are no longer the obvious, easy-to-spot calls they used to be — and that’s exactly what makes them so dangerous.
Think phone scams died off along with landlines? Think again. These schemes are more active than ever, and the people running them are getting genuinely sophisticated. They’re using stolen personal data, spoofed caller IDs, and convincing scripts to impersonate real companies like Microsoft, Dell, and Apple.
The result is that even tech-savvy employees can be fooled. For San Diego businesses, that’s a serious risk — because one successful scam call can open the door to a data breach, financial loss, or full network compromise.
Here’s what you need to know.
How Tech Support Scams Have Evolved
Early phone scams were easy to identify. A caller with a heavy accent would claim your computer had a virus and ask for remote access. Most people hung up immediately.
Today’s tech support scams are far more convincing. Scammers now obtain stolen data from prior breaches and use it to appear credible. In documented cases, callers have been able to tell victims the exact date of their last support call with Dell, the nature of the issue discussed, and their specific Service Tag Number — all information that would seem impossible for a scammer to know.
That level of detail creates immediate trust. And once trust is established, the victim is far more likely to follow instructions — including granting remote access to their computer.
4 Common Types of Tech Support Scams Targeting Businesses
1. The Fake Tech Support Call
A caller claims to represent Microsoft, Dell, Apple, or another well-known brand and tells the victim there’s a problem with their computer or network. The goal is to get the victim to visit a malicious website or grant remote access to their machine.
If remote access is granted, the scammer can install malware, steal credentials, access company files, or lock the system with ransomware.
2. The “Say Yes” Recording Scam
This one is deceptively simple. The caller asks a question designed to get the victim to say “yes” — then uses that recording to authorize fraudulent purchases or account changes in the victim’s name.
Employees who answer business phone lines are particularly vulnerable to this tactic.
3. Fake Software Sales
Scammers pose as software vendors and sell pirated, unlicensed, or malware-laced software at inflated prices. Victims end up paying hundreds or even thousands of dollars for software that either doesn’t work, violates licensing agreements, or actively harms their systems.
4. Phony Website Payment Capture
The caller directs the victim to a convincing but fraudulent website and asks them to enter payment information to “renew a subscription,” “verify account details,” or “pay for support services.” The payment information is then harvested and used for fraud.
Why Businesses Are Especially Vulnerable
Individual consumers are common targets, but businesses face an even greater risk for a few reasons.
First, employees aren’t always trained to spot these calls. A front desk employee or office manager who receives a convincing call from someone claiming to be from “Microsoft Support” may not know what questions to ask or what red flags to look for.
Second, business systems hold far more valuable data than personal computers — client records, financial information, employee data, and proprietary files. That makes a successful intrusion significantly more damaging.
Third, business owners who manage their own IT often don’t have the cybersecurity background to evaluate whether a call or request is legitimate. That’s not a criticism — it’s simply a different skill set. But it creates real exposure.
6 Warning Signs of a Tech Support Scam
Watch for these red flags in any unsolicited call:
- The caller claims your computer has a virus and they detected it remotely — without you initiating the call.
- They ask for remote access to your computer to “fix” the problem.
- They request payment for software, security tools, or support services you didn’t ask for.
- They direct you to a website from your command prompt or browser to “run a diagnostic.”
- They pressure you to act immediately, claiming your system is at risk right now.
- They ask you to confirm personal or account information to “verify your identity.”
If any of these happen in an unsolicited call, hang up. Legitimate companies like Microsoft and Dell do not make unsolicited calls to customers about computer problems.
How to Protect Your Business from Tech Support Scams
Train your team. Your employees are your first line of defense. Make sure everyone who answers phones or manages email knows what tech support scams look like and has a clear protocol for handling suspicious calls.
Establish a verification policy. Any unsolicited call requesting access, payment, or personal information should be escalated before anyone acts on it. A simple internal rule — “hang up and call the company directly using the number on their official website” — can prevent most scam attempts from succeeding.
Partner with a managed IT provider. When you have a dedicated IT team handling your security, suspicious calls can be forwarded directly to them. They can evaluate the situation immediately and take action if needed. This removes individual employees from having to make judgment calls they may not be equipped for.
