SSL stripping: Attackers cause the communication between two targets to no longer be encrypted, allowing them to perform a MITM attack.
Tips for preventing MITM attacks:
Check current Wi-Fi connections
Avoid logging into public Wi-Fi networks
Use a network sniffer
Watch for repeated or unexpected disconnections
Check strange addresses in the browser address bar
Check network connections to unknown locations
6. Ransomware attacks
Ransomware attacks were named the biggest threat to IT security last year . In these attacks, attackers threaten to publish the victim's data or block access to their systems if they do not pay a ransom.
With the increase in remote working, the number of cyberattacks has increased during the pandemic and companies are being forced to strengthen their cybersecurity methods. While this does not happen too often, in the worst case scenario, a ransomware attack can cause a company to go out of business.
There are several types of ransomware attacks:
Locker ransomware: Attackers lock users out of their systems completely or block basic computer functions and display the ransom demanded to be paid on the lock screen.
Crypto-ransomware: Attackers encrypt users' files and documents. Users can still see the data in the system, but cannot access it without a decryption key.

Tips for preventing ransomware attacks:
Check your systems regularly for ransomware
Ensure continuous operational readiness
Enforce Ransomware Governance
Inform stakeholders and employees about response plans in the event of ransomware attacks and conduct appropriate training
Hire a Ransomware Defense Expert
Use whitelists and anti-ransomware tools
Monitor unusual file activity such as failed modification attempts
7. SQL injection attacks
SQL injections (SQLi) use SQL code to compromise the security of networks or systems and gain access to information. Once injected into the system or network, the attacker can use the code to steal, delete, or edit information.
In-band SQLi: Attackers use the same channel to perform the attack uae telegram data and intercept information.
Inferential SQLi: Attackers send data to the server and observe the responses to learn more about its structure.
Out-of-Band SQLi: Attackers use the server's capacity to make DNS or HTTPS requests and transfer data.
Tips for preventing SQLi attacks:
Write code that identifies illegitimate user input
Use a firewall to detect and prevent SQLi attacks
Use data-centric strategies and focus on data protection in addition to protecting networks and applications
Use a SQL compliance management tool
Additional resources for protection against current cyberattacks
When it comes to cybersecurity, having the right technical tools is just as important as good employee training. The numerous cybersecurity tools and security training software solutions available will help you build the necessary defenses.
Regularly inform yourself and your team members about current cyber attacks and make safe behavior a habit at work as well as in your private life. More articles on cyber security:
