Frequently Asked Questions (FAQs)

Q1: How often should this ransomware playbook be updated and tested?

This playbook should be reviewed and updated at least annually, or whenever significant changes occur in the organization's IT infrastructure, threat landscape, or regulatory requirements. Crucially, it should be tested through tabletop exercises or simulated attack drills (e.g., red team exercises) at least twice a year to ensure its effectiveness and validate the readiness of the incident response team.

Q2: What should be the first step if an employee suspects a ransomware attack but isn't sure?

The absolute first step is to immediately report the suspicion to the IT Security team via the designated escalation channel (e.g., internal security hotline, dedicated email, or ticketing system). Employees should be instructed NOT to attempt to fix the issue themselves, power off their device (unless explicitly instructed), or disconnect from the network without guidance, as this could destroy critical forensic evidence. The IT Security team will then initiate the identification phase of the incident response plan.

Q3: Why is our company's policy against paying the ransomware? Doesn't paying ensure data recovery?

Our policy of not paying ransomware is based on several critical factors. Firstly, there is no guarantee that paying will result in the successful decryption of data; attackers often fail to provide working keys or provide incomplete ones. Secondly, paying fuels the ransomware economy, encouraging further attacks against other organizations. Thirdly, it may carry legal implications, particularly if the attackers are sanctioned entities. Instead, our strategy focuses on robust preventative measures, comprehensive immutable backups, and a highly capable incident response and recovery plan, which collectively provide a more reliable and responsible path to restoring operations without capitulating to cybercriminals.
