I'll be the first to admit I'm mediocre at exploit development, but I am in contact with enough extremely talented exploit developers to say this for certain: Anyone claiming they were "easily" able to generate a working php2shell exploit with AI is either: a) a world-class exploit developer with an extreme case of imposter syndrome. b) currently looking at some very confident-sounding but wrong LLM output. I'm rather certain it's the latter based on the number of AI-hallucinated exploits I've seen posted on GitHub. Threat actors are also blasting my honeypot network with "php2shell" exploits that not only don't work, but aren't even within 10,000 miles of anything to do with how the exploit actually works. I've seen the same technique from the attached image in multiple alleged "php2shell exploits", including one on GitHub with over 100 stars. Problem is, it's not php2shell, nor is it even a vulnerability at all. It's a technique known as "session poisoning", which can be leveraged to exploit local file inclusion (LFI) vulnerabilities in PHP apps (not PHP itself). The only thing it has in common with CVE-2026-109618/CVE-2026-109619 is they both use the "PHP_SESSION_UPLOAD_PROGRESS" feature. And mitigation advice for both issues reference setting "session.upload_progress.enabled" to "Off". People are shoving loose details of the vulnerability into LLMs, the LLMs are keying in on the "PHP_SESSION_UPLOAD_PROGRESS" string, then generating session poisoning code that has nothing to do with the actual CVE. And because the people doing this have absolutely no idea what they're doing, they're confident enough to post their "proof of concept exploit" to GitHub and share it on social media. So if you see people talking about "session poisoning + LFI" it's likely their LLM hallucinated an exploit based on a 2018 blog by Orange Tsai talking about a local file inclusion attack vector. What's even worse is that "security researchers" are then using LLMs to triage these exploitation attempts, falling victim to the same hallucinations, then confirming there is ongoing mass-exploitation (there currently isn't). The actual real exploit is very difficult to exploit, and so far I've not seen anyone successfully get it working on more than a handful of PHP version with highly-specific configurations. LLMs are useful tools in the hands of skilled professionals, but for others, they're often just a Dunning-Kruger accelerator.

🚨 Operation Serengeti III dismantles thousands of malicious cyber networks One of Africa’s largest cybercrime enforcement operations has seen agencies from 21 countries: 🔵 Arrest 1,462 suspects 🔵 Disrupt 10,909 malicious networks 🔵 Recover USD 105 million in illicit funds Under INTERPOL's coordination, investigators from participating countries joined forces to combat cyber-enabled fraud, ransomware, business email compromise, online scams and digital extortion. Authorities also identified 65,929 victims targeted by cybercriminal networks, underscoring the scale and sophistication of today's digital threats. Financial investigations linked criminal activity to losses exceeding USD 385 million. ➡️ 🔗 interpol.int/en/News-and-Eve…

Zero Day Initiative ha enviado, por error, 6 vulnerabilidades (alguna grave, con explicación y PoC) a la lista pública del Kernel, no a la privada. De hecho, en los propios correos pone que es confidencial. Greg Kroah-Hartman, responde un poquito harto ya. Revisad los procesos.

Paraguai fecha acordo com os EUA para vender energia excedente de Itaipu para data centers de IA. Isso pode representar um aumento de tarifas no Brasil pois esse excedente era antes vendido para o único cliente em potencial, o Brasil. Diferentemente do que crê a maioria das pessoas, sobra energia no Brasil em vez de faltar. Mas ela sobra durante o dia quando a produção solar é maior e de noite falta muitas vezes, exigindo ligar usinas termelétricas e poluentes. Essa sobra de energia durante o dia e a falta durante o horário de pico AUMENTA a tarifa de energia em vez de reduzir. Colocarei um vídeo a seguir nesse fio (thread) explicando isso melhor, o que tecnicamente é chamado de curtailment. Data centers são grandes consumidores de energia perene e têm muito capital próprio. Nos EUA já estão financiando o retrofit de usinas nucleares. Se conseguirmos atrair esse tipo de empresa para o país, eles poderão com seus contratos de longo prazo financiar a geração perene de energia e nos tirar desse paradoxo em que a tarifa residencial é mais cara porque sobra energia. Então no oposto do que diz a crendice popular, no Brasil um data center consomem menos água do que uma piscina olímpica e eles podem provocar a redução de tarifa de energia para residências em vez de aumentá-las. Siga o fio 🧶:

New research: in 2022, BlackLotus, a UEFI bootkit bypassing Secure Boot via CVE-2023-24932, went on sale on the dark web. Microsoft's fixes against this vulnerability didn't do their job fully. APT41 noticed that and reused the same bootkit against diplomatic targets! [1/n]

1/ Devs da Okta relataram semanas quase 4 horas mais curtas com o Copilot. Os pull requests por mês não subiram de forma significativa. Sugestão minha pra quem lidera: decidir antes pra onde as horas devolvidas vão. Os dados vêm a seguir.

Heads up, there is a 1-day full MikroTik RCE chain against SSH being used in the wild. Patch was released yesterday, so if you have a MikroTik router with ssh open on the internet, it may already be compromised. Detection guidance and IOCs courtesy of @CERT_Polska_en cert.pl/en/posts/2026/09/vul…
