How to prevent time bomb attacks

  • Software updates: Keeping your software up-to-date can fix your system's vulnerabilities that could be exploited by various malware, including time bombs.
  • Anti-malware software: Software, such as anti-spyware and antivirus programs, can detect, block and remove time bombs and similar malware.
  • Firewalls: Firewalls can block access to a system of the whole network. That means they are able to prevent time bomb malware from communicating with control servers.
  • Cybersecurity habits: Being cybersecurity literate should be mandatory. Avoiding suspicious emails, downloads, or unauthorized links must be evident to every internet user. It is advisable to have strong passwords and practice multi-factor authentication to prevent illegal access to valuable data.
  • Regular backups: Regular backups for valuable or critical data and information can help lower the damage caused by malware attacks, in this case, time bomb attacks.
  • Network segmentation implementation: Segmenting one's network can localize the spread of time bomb malware. Practicing data separation by rank can save valuable information from a less important one.
  • Prevention systems and intrusion detection tools: Using detection tools can detect time or logic bomb malware before they cause severe damage to the systems or networks.
