What is ransomware?
It’s malware that encrypts files on a computer or an entire network and then demands a ransom to unlock them. This is one of the most common cyber attacks, affecting both companies and individual users. These attacks can have catastrophic consequences for business, especially when key company data is locked.
How does ransomware work?
Types of ransomware
Among ransomware, there are several basic types:
- Crypto-ransomware – encrypts files on disk and demands a ransom to decrypt them.
- Locker ransomware – blocks access to the operating system, making it impossible to use the computer.
- Scareware – software that simulates an infection and threatens the user to extort payment.
Ways of infection
It most often spreads through:
- Phishing – emails with attachments or links leading to malware.
- Software flaws – vulnerabilities in system or application security can be exploited by cybercriminals.
- Outdated systems – failure to regularly update operating systems and applications increases the risk of infection.
Effects of ransomware attacks
Financial losses
Companies that fall victim to ransomware can suffer huge financial losses. The costs associated with paying the ransom, restoring data from backups, and business downtime can run into the thousands or even millions.
Loss of reputation
Data loss and recovery problems can lead to a loss of trust from customers and business partners. In particular, for Polish IT companies whose business is based on network security and data protection and data protection, such incidents can have serious image consequences.
Steps to protect yourself from ransomware
Choosing the right computer software
A key element in protecting against is choosing the right computer software. You should invest in antiviruses that detect and block malware. A good choice is the best antiviruses on the market that provide real-time protection and are updated regularly.
Regular system updates
Regularly updating IT systems and software is one of the basic steps in the fight against ransomware. Updates provided by software manufacturers include security patches that fix known security vulnerabilities.
Use of firewalls and VPNs
A firewall is a barrier between your computer and your network that blocks unauthorized connections. When combined with a VPN (Virtual Private Network), it allows secure access to company resources from anywhere. VPN top provides encryption of connections, which significantly increases network security.
Network security best practices
Secure data, access – VPN
A VPN protects against interception of data as it travels over the network. Thanks to encryption, data is protected from cyber criminals, which is especially important for remote work and remote access to company resources.
Web firewall and its importance
A web firewall is particularly useful in protecting web applications and information systems from attacks. It acts as a filter that blocks unauthorized requests to applications and provides an additional layer of protection.
The role of IT companies in protecting against ransomware
IT outsourcing as a way to increase security
Working with IT companies can significantly increase the level of protection against threats. Outsourcing IT allows you to benefit from the knowledge and experience of professionals who monitor company networks and implement best practices in cyber defense.
IT support for companies and implementation of security systems
IT support for companies includes not only network monitoring, but also the implementation and management of security systems. Implementation of a security system allows automatic detection and blocking of attempted attacks, as well as data backup.
Tools to support protection against ransomware
Antiviruses and their importance
Antivirus is an essential protection tool. The best antiviruses offer protection against various types of malware and real-time scanning, which minimizes the risk of infection.
Use of OPSWAT and Checkmk in threat monitoring
Tools such as OPSWAT i Checkmk allow real-time monitoring and management of network security. OPSWAT specializes in protecting files from file-based threats, while Checkmk enables monitoring of IT infrastructure to quickly detect anomalies.
Response to ransomware attack
What to do in case of infection?
When it comes to ransomware infections, quick action is key:
- Disconnect the infected device from the network to prevent the virus from spreading.
- Report the incident to the relevant departments and the IT company responsible for IT support.
- Take advantage of data backups to restore the system to its pre-infection state.
Mobile media scanning and threat removal
Scanning mobile media, such as external drives and USB flash drives, is an important step in removing ransomware. It’s also a good idea to use file scanning tools that automatically detect and remove malware from media.
Frequently asked questions
1 Is it worth investing in a VPN for ransomware protection?
Yes, a VPN provides data encryption, making it harder for cybercriminals to intercept data. This is especially important when working remotely, where data sent over the network is vulnerable to attacks.
3 What steps should be taken after a ransomware attack?
After an attack, it’s a good idea to disconnect infected devices from the network, report the incident to services, restore data from backups, and strengthen the company’s IT protection. In addition, it is worth conducting a security audit.
4. is IT outsourcing effective in the fight against ransomware?
IT outsourcing allows you to benefit from expert knowledge and monitor threats around the clock. This is an effective way to strengthen network security and respond to threats faster.
