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.

Part I of this series examined newly-leaked internal chats from the Conti ransomware group, and how the crime gang dealt with its own internal breaches. Part II explored what it's like to be an employee of Conti's sprawling organization. Today's Part III looks at how Conti abused a panoply of popular commercial security services to undermine the security of their targets, as well as how the team’s leaders strategized for the upper hand in ransom negotiations with victims.
