Every day, thousands of companies around the world fall victim to cyberattacks. Some realize it immediately; others take weeks or even months to notice their systems have been compromised. The worrying part is that most of these attacks could have been prevented with simple security practices.
At TecnetOne, we know that cybersecurity isn’t just about technology—it’s about awareness and good habits. That’s why, in this article, we’ll explain the most common types of cyberattacks against businesses and share practical tips to prevent them, without needing to be a tech expert.
Phishing is one of the most frequent and effective attacks. It involves fake emails, messages, or websites designed to impersonate legitimate companies to trick you into revealing sensitive information like passwords or banking details.
These messages often use urgency (“Your account will be suspended,” “Confirm your information now”) and links that redirect you to fake websites.
At TecnetOne, we recommend phishing simulations to test and strengthen your team’s cybersecurity awareness.
Ransomware is malware that encrypts your files and demands payment (a ransom) to restore access. In many cases, even paying doesn’t guarantee recovery.
This type of attack can completely paralyze a business, damage its reputation, and lead to serious financial losses.

Social engineering relies less on technology and more on manipulating people. Attackers pose as coworkers, vendors, or even authorities to trick you into revealing information or granting access.
They may call, text, or email pretending to need urgent help—counting on your willingness to respond quickly.
In a DDoS (Distributed Denial of Service) attack, hackers flood your servers with massive amounts of traffic, causing systems to slow down or crash. These attacks can disrupt your website, apps, or other critical services.
While DDoS attacks may not always steal data, they can disrupt operations and damage your reputation.
Malware includes viruses, trojans, spyware, and other malicious software designed to damage systems or steal information. It can enter through downloads, infected websites, USB devices, or emails.
Once installed, malware can log keystrokes, spy on users, or send data to attackers.
In spoofing attacks, hackers impersonate trusted sources—such as internal emails or legitimate websites—to deceive users and gain access.
For instance, they might fake your boss’s or a vendor’s email address to request a payment or access credentials.
Credential theft happens when attackers obtain usernames and passwords—often through phishing, malware, or leaked databases.
With these credentials, they can log into your systems, send emails on your behalf, or steal sensitive data.
Not all attacks come from outside. Sometimes, a disgruntled employee or contractor with authorized access intentionally causes harm or leaks information.
These cases are especially dangerous because insiders already understand your systems and security gaps.

No technical measure will be enough if your people aren’t aware of the risks. Most successful attacks start with a human mistake—a careless click, a weak password, or a suspicious email ignored.
That’s why at TecnetOne, we emphasize ongoing awareness and training as the foundation of every cybersecurity strategy. Teaching your team to spot and respond to threats is as important as having firewalls or antivirus software.
Cyberattacks keep evolving, but they all share one thing in common: they exploit distraction, misinformation, or lack of prevention.
At TecnetOne, we believe the best defense combines technology, awareness, and quick response. With clear policies, active monitoring, and informed employees, you can drastically reduce your company’s exposure to cyber risks.
Don’t wait to become a headline because of a data breach—prevention is your smartest investment.
