Sensibilisation des jeunes à la cybersécurité : la CNIL engagée dans l'Opération CACTUS
Une opération de sensibilisation en direction d’une cible particulièrement exposée Les établissements scolaires sont régulièrement ciblés par des attaques malveillantes via les espaces numériques de travail (ENT) des élèves. Ces actions cybercriminelles génèrent une forte pression sur les élèves, ce qui avait notamment conduit à la fermeture des ENT courant 2024.
Lucid is a sophisticated Phishing-as-a-Service (PhaaS) platform operated by Chinese-speaking threat actors, targeting 169 entities across 88 countries globally. With 129 active instances and 1000+ registered domains, Lucid ranks among prominent PhaaS platforms, alongside Darcula and Lighthouse. Its scalable, subscription-based model enables cybercriminals to conduct large-scale phishing campaigns to harvest credit card details for financial fraud. The platform employs an automated attack delivery mechanism, deploying customizable phishing websites distributed primarily through SMS-based lures. To enhance effectiveness, Lucid leverages Apple iMessage and Android’s RCS technology, bypassing traditional SMS spam filters and significantly increasing delivery and success rates. Lucid incorporates advanced anti-detection and evasion techniques, such as IP blocking and user-agent filtering, to prolong the lifespan of its phishing sites. Additionally, it features a built-in card generator, enabling threat actors to validate and exploit stolen payment data efficiently. Given its advanced infrastructure and persistent activity, Lucid poses a significant and ongoing cyber threat. Its operations underscore the growing reliance on PhaaS platforms to facilitate payment fraud and financial cybercrime, necessitating heightened vigilance and proactive mitigation efforts.
Next.js is an open-source web framework built by Vercel that powers React-based apps with features like server-side and static rendering. Recently, a critical vulnerability (CVE) was disclosed that lets attackers bypass middleware-based authorization checks. The issue was originally discovered and analyzed by Rachid Allam (zhero). In this blog, we’ll break down the vulnerability and walk through their research and will create a Nuclei template to help you detect it across your assets.
Troy Hunt: A Sneaky Phish Just Grabbed my Mailchimp Mailing List
You know when you're really jet lagged and really tired and the cogs in your head are just moving that little bit too slow? That's me right now, and the penny has just dropped that a Mailchimp phish has grabbed my credentials, logged into my account and exported the mailing list for this blog. I'm deliberately keeping this post very succinct to ensure the message goes out to my impacted subscribers ASAP, then I'll update the post with more details.
VanHelsingRaaS is a new and rapidly growing ransomware-as-a-service (RaaS) affiliate program launched on March 7, 2025. The RaaS model allows a wide range of participants, from experienced hackers to newcomers, to get involved with a $5,000 deposit. Affiliates keep 80% of the ransom payments, while the core operators earn 20%. The only rule is not to target the Commonwealth of Independent States (CIS). Check Point Research discovered two VanHelsing ransomware variants targeting Windows, but as the RaaS mentions in its advertisement, it provides more offerings “targeting Linux, BSD, ARM, and ESXi systems”. The program provides an intuitive control panel that simplifies operating ransomware attacks. Check Point Research obtained two variants of the VanHelsing Ransomware, compiled just five days apart. The newest variant shows significant updates, highlighting the fast-paced evolution of this ransomware. In less than two weeks since its introduction to the cybercrime community, this ransomware operation has already infected three known victims, demanding large ransom payments for decryption and the deletion of stolen data. During negotiations, they demanded $500,000 to be paid to a specified Bitcoin wallet.

Next.js and the corrupt middleware: the authorizing artifact
Recently, Yasser Allam, known by the pseudonym inzo_, and I, decided to team up for some research. We discussed potential targets and chose to begin by focusing on Next.js (130K stars on github, currently downloaded + 9,4 million times per week), a framework I know quite well and with which I already have fond memories, as evidenced by my previous work. Therefore, the “we” throughout this paper will naturally refer to the two of us. Next.js is a comprehensive javascript framework based on React, packed with numerous features — the perfect playground for diving into the intricacies of research. We set out, fueled by faith, curiosity, and resilience, to explore its lesser-known aspects, hunting for hidden treasures waiting to be found. It didn’t take long before we uncovered a great discovery in the middleware. The impact is considerable, with all versions affected, and no preconditions for exploitability — as we’ll demonstrate shortly.

A well-funded Moscow-based global ‘news’ has infected Western artificial intelligence tools worldwide with Russian propaganda
A Moscow-based disinformation network named “Pravda” — the Russian word for "truth" — is pursuing an ambitious strategy by deliberately infiltrating the retrieved data of artificial intelligence chatbots, publishing false claims and propaganda for the purpose of affecting the responses of AI models on topics in the news rather than by targeting human readers, NewsGuard has confirmed. By flooding search results and web crawlers with pro-Kremlin falsehoods, the network is distorting how large language models process and present news and information. The result: Massive amounts of Russian propaganda — 3,600,000 articles in 2024 — are now incorporated in the outputs of Western AI systems, infecting their responses with false claims and propaganda.
