Background for this topic.
Ransomware is malware used to deny access to systems or data, usually by encrypting files and demanding payment for decryption. Many operations also steal sensitive information and threaten to publish it, so an attack can create both an availability crisis and a privacy or disclosure risk. Initial access may involve phishing, stolen credentials, exposed remote services, or exploitation of unpatched vulnerabilities; attackers may then move through the network before deploying the payload.
Defenses should combine vulnerability management, phishing-resistant authentication where practical, endpoint and network monitoring, and backups that are isolated from routine administrator access and regularly tested for recovery. Organizations should also limit privileges and segment critical systems to reduce the blast radius. An incident requires rapid containment, preservation of forensic evidence, restoration from known-good backups, and assessment of notification, legal, and regulatory obligations. Threat intelligence can help identify relevant criminal infrastructure or tactics, but it does not replace sound access control, patching, detection, and recovery practices.

In 2023, the cryptocurrency industry faced a significant increase in illicit activities, including money laundering, fraud, and ransomware attacks. Ransomware attacks were especially prevalent and profitable for attackers. However, other forms of criminal activity also saw a rise.
The CE giant released its investigative findings regarding a March cyberattack that resulted in data exfiltration affecting its Japanese operations.

A Cisco report highlighted TTPs used by the most prominent ransomware groups to evade detection, establish persistence and exfiltrate sensitive data
It’s the age of identity security. The explosion of driven ransomware attacks has made CISOs and security teams realize that identity protection lags 20 years behind their endpoints and networks. This realization is mainly due to the transformation of lateral movement from fine art, found in APT and top cybercrime groups only, to a commodity skill used in almost every ransomware attack. The
The ransomware-as-a-service platform just rolled off the assembly line, also targets Windows, and uses Golang for cross-platform capabilities.
Group-IB also revealed the ransomware uses Chacha20 and RSA-OAEP for encryption
Researchers at Avast found a flaw in the cryptographic schema of the DoNex ransomware and have been sending out decryptor keys to victims since March 2024
Now may be a good time to find good deals on insurance coverage for ransomware and security incidents.
An emerging ransomware-as-a-service (RaaS) operation called Eldorado comes with locker variants to encrypt files on Windows and Linux systems
Events like the recent massive CDK ransomware attack – which shuttered car dealerships across the U.S. in late June 2024 – barely raise public eyebrows anymore. Yet businesses, and the people that lead them, are justifiably jittery. Every CISO knows that cybersecurity is an increasingly hot topic for executives and board members alike. And when the inevitable CISO/Board briefing rolls
