Ad fraud networks use bots, deepfakes and spoofed traffic to drain PPC budgets. This report shows how fake clicks distort performance data.

Threat actors are using the open-source phishing framework Evilginx to target universities across the United States, according to researchers at Infoblox. The attackers have targeted at least 18 universities and educational entities since April 2025, using phishing pages that spoofed student single sign-on (SSO) portals.

Threat actors with ties to North Korea have likely become the latest to exploit the recently disclosed critical security React2Shell flaw in React Server Components (RSC) to deliver a previously undocumented remote access trojan dubbed EtherRAT. "EtherRAT leverages Ethereum smart contracts for command-and-control (C2) resolution, deploys five independent Linux persistence mechanisms, and

Europol and Eurojust led a massive international police operation that successfully dismantled a crypto fraud network that laundered over €700M using deepfake ads.

Four distinct threat activity clusters have been observed leveraging a malware loader known as CastleLoader, strengthening the previous assessment that the tool is offered to other threat actors under a malware-as-a-service (MaaS) model. The threat actor behind CastleLoader has been assigned the name GrayBravo by Recorded Future's Insikt Group, which was previously tracking it as TAG-150.

Google AI systems (Gemini Enterprise) had a critical 'GeminiJack' security flaw allowing attackers to steal Gmail, Docs, and Calendar data with no clicks.

The threat actor known as Storm-0249 is likely shifting from its role as an initial access broker to adopt a combination of more advanced tactics like domain spoofing, DLL side-loading, and fileless PowerShell execution to facilitate ransomware attacks. "These methods allow them to bypass defenses, infiltrate networks, maintain persistence, and operate undetected, raising serious concerns for

Major League Hacking (MLH) is excited to announce a new initiative to expand access to blockchain education and hands-on learning for next-gen developers worldwide, with a focus on Solana, the fastest-growing blockchain ecosystem.

We’re creating new ways for students and next-gen developers to learn, build, and explore the future of decentralized technology. As of December 2025, Solana will debut at MLH hackathons across the world, offering participants hands-on opportunities to experiment with blockchain development. Through workshops, technical challenges, and mentorship, developers will be able to gain practical experience building on Solana in a supportive environment designed for learning-by-doing.

Learning by Doing, Supported by Solana Technology

At MLH, our mission has always been to help developers learn by doing. This initiative builds directly on that philosophy by giving students access to the tools, resources, and guidance they need to turn ideas into real, deployable projects.

Solana’s debut at MLH hackathons represents more than a new track. It’s an invitation for student developers to join an active, global ecosystem. By bringing Solana technology directly into hackathon environments, we’re helping hackers take their first steps into blockchain development with the tools and mentorship to succeed.

Building Beyond the Hackathon: The Solana Micro-Grant Program

One of the most exciting parts of this initiative is the launch of the Solana Micro-Grant Program, coming later this year.

Through this initiative, MLH and Solana will award up to 75 developer micro-grants through December 2026, helping promising projects continue long after the hackathon weekend ends. These grants will support a wide range of projects, from developer tooling and educational templates to early-stage startups and public-good infrastructure that strengthen the Solana ecosystem.

In addition to funding, grant recipients will receive mentorship and community exposure, helping them grow their projects and connect with other builders in the Solana network. It’s another way MLH helps ensure that great ideas don’t just start at hackathons; they keep growing.

Expanding Hands-On Blockchain Education

The initiative will also extend to our Fellowship Program, where students will have opportunities to contribute directly to Solana-related open-source projects in place of a traditional internship. This means students won’t just learn how blockchain works. They’ll build real-world software that powers it.

Additional educational support, including workshops, developer challenges, and learning content, will help participants understand key concepts in Solana program development, payments, and AI.

A Global Opportunity for Builders

While the initial rollout focuses on North America, the initiative will soon expand globally through initiatives like 100 Days of Solana, an open developer learning challenge that invites hackers from around the world to explore blockchain development together.

This aligns with MLH’s commitment to accessibility and inclusion in tech. Our community already spans over one million student developers across 98 countries, and with Solana’s involvement, even more hackers will have access to cutting-edge tools, mentorship, and funding opportunities.

What This Means for the MLH Community

This initiative represents a natural evolution of MLH’s mission: to bridge the gap between academic learning and real-world experience. By integrating Solana’s technology and developer ecosystem into MLH programs, we’re helping next-gen developers gain future-ready skills and the confidence to apply them in meaningful ways.
