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.
Threat actor exploited known vulnerabilities in the Microsoft software to compromise multiple systems An affiliate of the aggressive Hive ransomware group is exploiting known vulnerabilities in Microsoft Exchange servers to encrypt and exfiltrate data and threaten to publicly disclose the information if the ransom isn't paid.…
KrebsOnSecurity recently reviewed a copy of the private chat messages between members of the LAPSUS$ cybercrime group in the week leading up to the arrest of its most active members last month. The logs show LAPSUS$ breached T-Mobile multiple times in March, stealing source code for a range of company projects. T-Mobile says no customer or government information was stolen in the intrusion. LAPSUS$ is known for stealing data and then demanding a ransom not to publish or sell it. But the leaked chats indicate this mercenary activity was of little interest to the tyrannical teenage leader of LAPSUS$, whose obsession with stealing and leaking proprietary computer source code from the world’s largest tech companies ultimately led to the group’s undoing.
