In today's digital landscape, where data is the lifeblood of any business, securing and protecting hypervisor environments is paramount. Hypervisors, such as OpenShift Virtualization and Proxmox VE, play a critical role in virtualized environments. The threat landscape constantly evolves, with cyberattacks becoming more sophisticated and data breaches rising.

Human illness is inevitable. So are data breaches. In 2023 alone, there were 10,626 confirmed data breaches, doubling that in 2022 (5,199 breaches). You cannot protect yourself 100% from getting ill. But you can proactively adopt a healthy lifestyle and habits to help reduce the risk and the impact of an illness and recover quickly. Similarly, your organization cannot protect itself 100% from the outcome of a data breach.

A significant ransomware attack on Infosys McCamish Systems, an outsourcing service provider for financial and insurance companies, has impacted over six million customers. The breach, which took place in late 2023, was only recently disclosed in a filing with the Maine Office of the Attorney General (OAG). This incident underscores the importance of robust cybersecurity measures such as stolen credentials detection, darknet monitoring services, and digital footprint analysis.

What likely started as a quick ransomware “smash and grab” has turned into a headline case resulting in responses from both U.K. and U.S. law enforcement. Earlier this month, several larger London hospitals suddenly had no access to lab results. It turned out to be the result of a ransomware attack on laboratory partner Synnovis that crippled hospitals and health services that rely on Synnovis.

Welcome to the latest from Corelight Labs! This blog continues our tradition of picking a popular malware family from Any.Run and writing a detector for it! Trending consistently at #1 on Any.Run’s malware trends list, Agent Tesla uses multiple protocols to communicate with its C2 infrastructure, making it more difficult to detect robustly than a malware sample utilizing only one network protocol for its C2.

Ransomware attacks are a huge problem: in the past five years alone, they have brought about a state of emergency across vast swathes of the United States, threatened to topple the Costa Rican government, and brought Portugal's largest media conglomerate to its knees. And ransomware attackers show no signs of slowing down: last year, roughly one-third of all data breaches involved ransomware or some other extortion technique.

Researchers at ESET warn that malvertising campaigns are impersonating AI tools to trick users into installing malware. The Rilide infostealer, for example, is being distributed via a malicious browser extension posing as Sora or Gemini. “In the case of the malicious browser extension, it is delivered to victims who have been duped into clicking on malicious ads, typically on Facebook, that promise the services of a generative AI model,” the researchers write.

Cyber threats pose a significant risk to virtualized infrastructure. According to the latest Rubrik Zero Labs report, 83% of encrypted data across all industries is within a virtualized architecture. Virtualized architectures typically have less security coverage than traditional endpoints. This creates security dead spots and consequently allows attackers unfettered access.

In Arctic Wolf’s The State of Cybersecurity: 2024 Trends Report, we asked organizations what their primary area of concern was regarding cybersecurity, and for the third year running the answer was crystal clear: Ransomware.
