During a recent ransomware incident investigated by the Quorum Cyber Incident Response team, novel malware was identified previously unknown.
A massive Magniber ransomware campaign is underway, encrypting home users' devices worldwide and demanding thousand-dollar ransoms to receive a decryptor.
Magniber launched in 2017 as a successor to the Cerber ransomware operation when it was spotted being distributed by the Magnitude exploit kit.
Since then, the ransomware operation has seen bursts of activity over the years, with the threat actors utilizing various methods to distribute Magniber and encrypt devices. These tactics include using Windows zero-days, fake Windows and browser updates, and trojanized software cracks and key generators.
A major company made a staggering $75 million ransomware payment to hackers earlier this year, according to cybersecurity vendor Zscaler.
Zscaler made the claim in a Tuesday report examining the latest trends in ransomware attacks, which continue to ensnare companies, hospitals, and schools across the country.
A cyberattack has hit a blood-donation nonprofit that serves hundreds of hospitals in the southeastern US.
The hack, which was first reported by CNN, has raised concerns about potential impacts on OneBlood’s service to some hospitals, multiple sources familiar with the matter said, and the incident is being investigated as a potential ransomware attack.
Microsoft researchers have uncovered a vulnerability in ESXi hypervisors being exploited by several ransomware operators to obtain full administrative permissions on domain-joined ESXi hypervisors. ESXi is a bare-metal hypervisor that is installed directly onto a physical server and provides direct access and control of underlying resources. ESXi hypervisors host virtual machines that may include critical servers in a network. In a ransomware attack, having full administrative permission on an ESXi hypervisor can mean that the threat actor can encrypt the file system, which may affect the ability of the hosted servers to run and function. It also allows the threat actor to access hosted VMs and possibly to exfiltrate data or move laterally within the network.
On May 2, 2024, Arctic Wolf Labs began monitoring deployment of a new ransomware variant referred to as Fog. The ransomware activity was observed in several Arctic Wolf Incident Response cases, each exhibiting similar elements. All victim organizations were located in the United States, 80% of which were in the education sector and 20% in the recreation sector.
We are sharing details of this emerging variant to help organizations defend against this threat. Please note that we may add further detail to this article as we uncover additional information in our ongoing investigation.
Delaying security updates and neglecting regular reviews created vulnerabilities that were exploited by attackers, resulting in severe ransomware consequences.

Researchers from Avast have discovered a flaw in the cryptographic schema of the DoNex ransomware and its predecessors. In cooperation with law enforcement organizations, we have been silently providing the decryptor to DoNex ransomware victims since March 2024. The cryptographic weakness was made public at Recon 2024 and therefore we have no reason to keep […]
