The coronavirus pandemic has affected businesses across all industries. Some companies are forced to accommodate work-from-home arrangements despite the corporate network risks that come with the setup. Employees need a more powerful security measure like Bitdefender Business other than just one antivirus software to ensure that their work devices are safe from cyberattacks.


Due to the sudden shift to remote operations, many businesses are left with unsecured systems and vulnerable hardware that employees took home.


Of course, cybercriminals spared no time attempting to get into their targets’ systems. Hackers have been using known techniques and attacking common entry points to get into users’ networks and devices. The sudden switch to a remote work setup works in their favor since companies have left their employees vulnerable without any network security tools like Bitdefender Business.


Cybercriminals try to gain access through several methods from default passwords and revisiting unpatched vulnerabilities, to scanning for open ports and services.

Bitdefender Business Guide Signs of a Cybercrime Attack

Generally, the best way to detect if your network is infected by any malicious ware is through layers of security measures. Most people will stop at antivirus, but when your business and all your client details are on the line– it’s for the best if you can set up a better security system for your corporate network.


For instance, Bitdefender Business security products offer an all-in-one solution that includes protection and unified security management for workstations, servers, email, and devices. They can help detect malware, virus, and other threats without all the fuzz of handling multiple software thanks to a unified security management platform.


Most malicious routines and wares do not show obvious signs or symptoms until after certain user actions– which is why a solid network security system is recommended. However, here are some common signs of malware infection and intrusion that you can look out from:


  1. Unusual network traffic or activity
  2. Disconnection from network service
  3. Irregular system entries (like users obtaining access without authorized means)
  4. Records of failed login attempts
  5. New user accounts of questionable origins
  6. Unusual log entries to unfamiliar machines or services
  7. Unexplained new files of unknown origin and function
  8. Unusual changes in file sizes, date, and time stamps especially to files related to system binaries
  9. Unexplained addition, removal, or modification of data
  10. System crashes
  11. Unauthorized operation of a program or software
  12. Unusual usage times (for instance, usage after working hours)


If your system seems to work less efficiently, then your network might be compromised. Signs of intrusion can come in the form of unusual system activities or the form of poor system performance. Although this can be prevented with an efficient cybersecurity solution with the help of Bitdefender Business products.


How Did Your Network Get Compromised?

How Did Your Network Get Compromised

Cybercriminals are getting creative nowadays. They are improving their techniques for gaining illegal access to sensitive files and data. Their opportunities are growing due to the expanding array of devices that can connect to corporate networks. Some businesses and employees are also left vulnerable because of the sudden switch to a remote work setup.


If your network and devices are not protected by any security system like Bitdefender Business products, then you need to understand how cybercriminals infect their target’s network.


Here are the possible ways hackers can get through to your network:


Third-Party Websites and Downloads


Cybercriminals can access your network through third-party websites or anything that you download to your devices. It can be an app, software, or media embedded with malicious components.


Public WiFi Networks


Some hackers have the resources to steal information that goes through public networks. Once they infect your device, they can easily steal sensitive data from your company once you connect to your corporate network.




Phishing emails and links have been around for a long time, but cybercriminals are getting better at disguising their scams. Phishing emails and links can help gain access to your device, steal sensitive data, or spread malware. 


Outdated System


Not updating your system can leave some security gaps that cybercriminals can abuse. Make sure to keep all your system, apps, and software updated to prevent cyber attacks. Thus, with security tools like Bitdefender Business, you can rest assured your system is up-to-date. 


Default Access Credentials


Default access credentials (usernames and passwords) make it easy for hackers to get into your network. Cybercriminals can simply guess or refer to a common list to access your devices for attacks. 




Network security should be a priority even with a remote work setup. Both companies and employees should do their part in keeping their corporate network safe. 

Company owners can start by investing in network security measures like Bitdefender Business products to keep work devices and the office network safe. And employees should be more vigilant while working at home.
