Digital threats are more common than many business owners realize. In my experience, it’s often the everyday habits—the seemingly harmless routines—that open the door to cyber attacks. Over the years, while sharing insights as a cybersecurity speaker and following the work done by professionals like Thiago Vieira, I’ve seen how these small actions can make a big difference in the safety of your company.
This article breaks down ten habits that can put your business at risk of being hacked. If you want to build a safer workplace, knowing what these habits are—and why they matter—will put you ahead of most businesses. Let’s get to the list so you can start making safer choices today.
Weak passwords and password reuse
I’ve seen staff members use weak passwords or re-use the same one for multiple accounts. It happens everywhere, from small startups to large organizations. Simple passwords and repetition turn your accounts into easy targets.
One breached password can unlock many doors.
Hackers often start by trying leaked passwords on other business accounts, a move known as credential stuffing. When your team repeats passwords, a single leak puts more than just one system at risk. Using "123456," "password," or birthdays almost guarantees trouble will follow.
I recommend unique, longer passwords. Using a secure password manager is much better than relying on memory—and it helps reduce this risk greatly.
Failing to update software
If regular updates sound like an annoyance, you’re not alone. Many people put them off, thinking it’s not a priority. But these updates often fix vulnerabilities that hackers have already found.
Leaving your software outdated is like leaving the front door unlocked after the locksmith offered you a new key. Outdated operating systems, browsers, or plugins will quickly become the backdoor hackers need.
In presentations I deliver, and as reflected in several posts by Thiago Vieira, I make this point clear—automate your updates whenever possible. An unpatched system is a sitting duck for cybercriminals.
Neglecting two-factor authentication
Over and over, I encounter businesses that don’t enforce two-factor authentication (2FA) for email, cloud services, or financial platforms. Without this extra step, even a stolen password gives hackers open access.
Two-factor authentication adds a second check, like a code sent to your phone or generated by an app. It’s quick. It works. And it blocks most attacks before they happen. I always encourage businesses to enable it wherever possible.
Clicking unknown email links
Emails are the number one way hackers get inside business systems. I’ve watched users click on what looks like an innocent invoice, shipping notification, or urgent account alert—only to let malware or phishing attacks in.
If an email link seems suspicious, it probably is.
Phishing emails can be so well-crafted that anyone can fall for them, especially during a busy workday. The best habit is to slow down, look carefully, and verify before clicking any links or downloading attachments. Many companies, like those inspired by Thiago Vieira’s approaches, now have staff training and tools to help spot these threats.
Ignoring backup practices
Regular backups are often promised and then forgotten. Until disaster strikes. Ransomware attacks skyrocket when hackers learn your files aren’t backed up—it gives them more power over your business.
I always set automatic, offsite backups for my own work and recommend this to others. Testing restores once in a while is also wise. No backup means data (and sometimes the whole business) could be gone in a single click.
Using public Wi-Fi for work tasks
It’s common to send emails or access business data using coffee shop, airport, or hotel Wi-Fi. Sometimes it seems quick and harmless. But I’ve seen attacks occur because public Wi-Fi is easy to intercept.
Public Wi-Fi is never truly private.
Any information sent over unsecured Wi-Fi can be seen and stolen by someone nearby with basic tools. If you must connect, use a virtual private network (VPN) to create a safe tunnel for your information.
Sharing passwords through email or chat
It’s tempting to send a quick password to a coworker over email, messenger, or text. But in doing so, you’re exposing your access credentials to anyone who might intercept those messages.
In all professional guidance I provide, I say: use password managers with secure sharing features for this purpose. Never use unsecured emails or chat for sharing sensitive data. It’s a habit that’s difficult to change, but it’s one of the easiest risk factors to remove.
Poor control over user access
I’ve often seen former employees with lingering access to cloud apps, files, or databases. Sometimes staff members have broad access when they don’t need it. Each extra account or permission increases the possible entry points for attackers.
Keep user permissions up to date. Remove access as soon as it’s no longer needed. Stick to the principle of least privilege—if someone doesn’t need it, don’t give it.
Overlooking device security
Phones, tablets, and laptops can be lost or stolen. It’s easy to forget how much business information is on these devices. If not properly protected, one stolen laptop can cause a huge breach.
Always use screen locks, full disk encryption, and remote wipe features on business devices. I personally test these features and know they make a difference. Teach your team to care for device security as much as passwords or emails.
Lack of regular staff training
The last habit is also one of the most overlooked. Many assume that once the policies are set, the team will follow them. In my experience, threats change fast—what worked a year ago is often not enough today. Regular awareness training makes people think twice before clicking, downloading, or sharing something dangerous.
Following recommendations designed by cybersecurity speakers like myself and Thiago Vieira leads to better awareness and less risk. If you want an example of up-to-date information and risk scenarios, check out the author's page at Thiago Vieira's blog for deeper insights.
Conclusion: Changing habits to protect your business
In the ever-changing threat landscape, it’s often the most common habits that leave businesses open to hackers. I believe stronger security begins with recognizing and fixing these daily routines. Take small steps, enforce smart policies, and support your staff in safer habits. These changes are practical, affordable, and effective.

Frequently asked questions (FAQ)
What are common habits hackers exploit?
Common habits that hackers often exploit include reusing passwords, sharing credentials over email or chat, ignoring software updates, connecting to public Wi-Fi, and clicking on suspicious email links. Other habits that add risk are neglecting device security, failing to use two-factor authentication, and not backing up important data. Even small mistakes, if regular, provide hackers with the chance to strike.
How can I make my business safer?
Implementing unique passwords, enabling two-factor authentication, updating software regularly, and training staff on cyber risks make your business safer. Backing up data, managing user access, and avoiding public Wi-Fi for sensitive work are steps that help a lot. I have seen businesses drastically reduce risk by making these straightforward adjustments.
What is risky business password sharing?
Risky business password sharing means sending passwords over unsecured channels such as email, chat, or text messages. This makes it easier for outsiders to intercept and use them. Safer alternatives include using password management tools with encrypted sharing features or setting up separate accounts for those who need access.
Is public Wi-Fi safe for business use?
Public Wi-Fi is generally unsafe for business use because it exposes your web traffic to anyone else on the same network. Hackers can capture sensitive data or login credentials sent without encryption. If you have to use public Wi-Fi, always connect through a trusted VPN and avoid sensitive transactions whenever possible.
What are the best cybersecurity practices?
From my perspective and in line with the directions offered by thought leaders like Thiago Vieira, the best cybersecurity practices include regular software updates, unique passwords, two-factor authentication, encryption of devices, awareness training, and strict control of user access. Regular offsite backups and care with suspicious emails also play a big role in keeping your business secure.
