Beware that “support call” – it could be a ransomware scam

If you get a call claiming to be from Microsoft Teams support, think twice before doing what they ask.

There’s a new trend for scammers to pose as “help desk” staff, with the aim of tricking employees into letting them take over their devices.

This is part of a larger ransomware attack, where you’ll be denied access to your business data unless you make a hefty payment to get it back.

Recently, a notorious cyber crime group has taken this scam to a new level.

First, they’ll flood an employee’s inbox with so much spam that it becomes unusable. Then they swoop in with a phone call, pretending to be from IT support, offering to “fix” the problem.

They may ask your employee to install remote desktop software like AnyDesk or use built-in tools like Windows Quick Assist. Once they have access, they can move around your network, collect sensitive data, and launch ransomware on your devices.

Be warned – they don’t only reach out over the phone. They’ve also started setting up Teams accounts to make employees think they’re part of IT support.

They do this by choosing usernames like “Help Desk” and using fake Microsoft tenant domains such as “securityadminhelper.onmicrosoft .com”. Then they send one-to-one messages to employees, saying they need access to their device.

Ransomware attacks are serious business. Along with locking you out of your data, they can also shut down your operations, disrupt customer service, and potentially leak confidential information.

Recovering from a ransomware attack can be expensive, both in terms of paying the ransom and dealing with the aftermath. It can cause loss of revenue, damage your reputation, and it could even have legal consequences.

Make your team aware of this scam and encourage everyone to be cautious with any unsolicited support calls or Teams chats. And make sure everyone knows to check with your actual IT department first, if someone is asking to install software or gain access.

Also, if you use Microsoft Teams in your business, make sure it’s set up securely. Only allow external chats from trusted domains, and make sure chat logging is enabled.

How to create secure passwords

How to create secure passwords

Weak passwords are one of the biggest security risks to your business.
Why?
Because cyber criminals are getting smarter than ever before. If they manage to crack just one password, they could gain access to your sensitive business data, financial information, or even gain control of your entire system.
Cyber criminals use automated tools to guess passwords, allowing them to try out millions of combinations in seconds. So, if you’re using something like “Password123” or “CompanyName2025”, you’re practically handing them the keys to your business.
A compromised password can lead to big issues, such as:
• Data breaches
• Financial losses
• Identity theft
• Reputation damage
But how do you create strong passwords without driving yourself (and your team) mad?
Think of your password like a secret recipe, where only you should know the ingredients. It should:
• Be at least 14 characters long (the longer, the better)
• Include a mix of uppercase and lowercase letters
• Contain a few numbers and symbols (like @, $, %, or &)
• Not contain any common words or easily guessable information (like birthdays, names, or the word “password”)
Instead of using a single word, you could try a passphrase – a short, random sentence that only you would understand. For example, instead of “Sailing2025”, try something like “Coffee&CloudsAreGreat9!”. This is much harder to crack, yet still easy to remember.
You should also steer clear of these common mistakes:
• Using personal info (your name, birthday, business name, etc.)
• Reusing the same passwords across multiple accounts
• Using simple sequences (“123456” or “abcdef”)
• Storing passwords in an easily accessible place (like a sticky note on your desk)
If remembering unique passwords for every account sounds impossible, there is another option: Password managers. These generate strong passwords, store them securely and autofill them for you.
With a password manager, you only need to remember one strong master password for the manager app itself. The rest are encrypted and stored safely, reducing the risk of data breaches.
Even the strongest password isn’t foolproof, which is why multi-factor authentication (MFA) is also important. MFA requires a second form of verification, like a one-time code sent to your phone or generated from an authentication app.
If you have employees accessing your business systems, it’s a good idea to have a password policy in place to explain your rules and why they’re important. This should include:
• Unique passwords for each system and account
• Regular security training on password best practices
• Business-wide use of MFA for critical systems
• Scanning for compromised passwords regularly
By making password security a priority, you can reduce the chances of a cyber attack creating a nightmare for your business.
