We scanned thousands of hosts for CVE-2026-48710 and found something important: being behind a reverse proxy, CDN, or Cloudflare is not always enough protection. In some setups, X-Forwarded-Host can still be used as a bypass. (1/2)
Huge shoutout to @calif_io (@Icfr_hax) for discovering PHP2Shell (CVE-2026-109618/19)
Patching is only half the battle. Within 24h, we built #Nemesis simulations to safely test real attacks and prove your defenses actually work

#PHP2Shell #ThreatToTest
Conversations at @_c0c0n_ 2026 proved enterprise teams want advanced #securityvalidation without sending sensitive logs to external clouds.
That’s why we built #Nemesis full on-prem execution with zero data leakage. Great connecting with defenders!

Some environments thrive in the cloud, others demand on-premise control especially in regulated sectors
Nemesis handles both effortlessly by running #localAI model inside your own system.
Get continuous attack validation w/o compromising on where your data lives.

We’re heading to Techtonics!
Our co-founder Babette De Decker will be there representing Nemesis, ready to catch up w familiar faces, make new connections and talk about where defenses break down.
If you're attending, come say hi 👋

🤖 Made with AI
Our co-founder @marver caught up with @benarent, Rob Picard to discuss #AI; #redteam vs. #blueteam
Partnering w @goteleport for NYC security speakeasy was amazing, they’re such great people to collaborate with.
🫣 In the end, does your AI beat their AI?

Loved catching up with old friends and making new ones at @_c0c0n_ 2026!
Getting such a warm welcome from Kerala Police was a highlight, along with @marver's training session.
Big thanks to the organizers, volunteers and speakers for a great event 👋
#c0c0n2026 #cybersecurity
4 Days To Go! We’re teaming up with @AikidoSecurity at A6K for a Brown Paper Bag Session on what no one actually tells you about scaling a cyber startup.
Our Co-founder Babette De Decker will be there sharing lessons and honest takeaways.
#Nemesis #Networking #offensivesecurity
Beyond the talk, it’s a great chance to grab lunch, connect with the community and swap ideas on where cybersecurity is heading.
If you’re around, drop by and say hello 👋

🎙️ @marver is taking the stage at @offbyoneconf to break down the sheer chaos of AI security!
Between indirect prompt injection & models executing untrusted code, context has officially become the new attack surface.
If you’re at the event and want to catch up, drop us a line!
🧐If you’ve been holding off an AI-driven security testing because of strict compliance, we get it!
🥳Introducing Nemesis’s On-Prem Local AI, you can run continuous attack simulations powered by a custom model hosted entirely on your systems.

Berlin's breach proves defenses need #continuousvalidation. Know controls work before hackers test them!
#Nemesis turns your threat profile into practical on-prem assessments; executing #MITRE ATT&CK techniques to map attack paths & convert missed TTPs to Sigma rules.

Great fun interviewing @marver of @Persistent_Psi and Rob of @goteleport ; for last nights Offensive vs Defensive in the Age of AI
The difference between pulling your hair out over endless alert and finishing your shift usually comes down to your stack. Nemesis's One-Click Intelligence handles the repetitive triage so you can jump straight to quick, clear resolutions.
