The Everest ransomware gang's dark web leak site was hacked and defaced on April 7, 2025, with attackers replacing the content with the message "Don't do crime CRIME IS BAD xoxo from Prague"[^1]. The site subsequently went offline and displayed an "Onion site not found" error[^1].

Flare Senior Threat Intelligence Researcher Tammy Harper suggested the breach likely exploited vulnerabilities in the site's WordPress template[^1]. The attack disrupted Everest's operations, which had evolved since 2020 from data theft extortion to include ransomware deployment and selling network access to other cybercriminals[^2].

Prior to the breach, Everest had claimed over 230 victims on its leak site, including recent attacks on cannabis retailer STIIIZY and increased targeting of U.S. healthcare organizations in 2024[^1][^3]. The group operated as both a ransomware outfit and initial access broker, selling compromised network access to other threat actors[^4].

Proton batteries are emerging as a promising alternative to lithium-ion batteries for energy storage, offering several key advantages. Recent research from UNSW Sydney has demonstrated a breakthrough in proton battery technology using a novel organic material called tetraamino-benzoquinone (TABQ)[^6].

The technology works by storing protons (hydrogen ions) rather than lithium ions, leveraging their unique properties as the smallest and lightest ions of any element[^7]. The UNSW prototype achieved 3,500 charging cycles while performing well even in sub-zero temperatures[^6].

Key benefits of proton batteries include:

• Fast charging capabilities
• Zero carbon emissions
• Lower environmental impact
• Enhanced safety due to water-based electrolytes
• Potential lower costs due to abundant materials
• High energy and power density

The primary challenges currently facing proton battery development include:

• High production costs for electrode materials
• Limited voltage range in existing organic electrode materials
• Technology still in early development stages[^6]

Professor Chuan Zhao from UNSW notes: "The electrolyte in a lithium-ion battery is made of lithium salt, a solvent which is flammable and therefore is a big concern. In our case, we have both electrodes made of organic molecules, and in between we have the water solution, making our prototype battery lightweight, safe and affordable."[^6]
