Background for this topic.
Ransomware is malicious software that disrupts access to systems or data, typically by encrypting files, to pressure a victim into paying. Modern campaigns may also steal data and threaten to publish it, making the demand a form of extortion even when encryption is unsuccessful. Common access routes include phishing, exposed remote services, stolen credentials, and unpatched vulnerabilities, though no single route is universal.
Important safeguards include regularly tested, offline or otherwise isolated backups; multifactor authentication and least-privilege access; network segmentation; and timely remediation of known, internet-facing vulnerabilities. During an incident, organizations should isolate affected systems, preserve evidence, identify the scope of compromise, and coordinate recovery and legal or regulatory decisions. Payment does not guarantee data recovery or deletion. Threat intelligence may help identify associated infrastructure or available decryptors, while documented recovery plans reduce dependence on an attacker’s demands.
Though the Chicago-area hospital did not pay a ransom, a host of sensitive medical information is now at risk.
Episode 2: Incident response experts-turned-ransomware negotiators Ed Dubrovsky, COO and managing partner of CYPFER, and Joe Tarraf, chief delivery officer of Surefire Cyber, explain how they interact with cyber threat actors who hold victim organizations' systems and data for ransom. Among their fascinating stories: how they negotiated with cybercriminals to restore operations in a hospital NICU where lives were at stake, and how they helped a church, where the attackers themselves "got a little religion."
More than 200 regional and national government agencies have been impacted by the ransomware attack, and few of them are once again operational.
