Someone found an RCE on my website yesterday. CVE-2025-55182. React2Shell. I don't have a bug bounty program. I never asked for a security assessment. I woke up to a DM: "Hey I found a critical vulnerability in your site. I only ran the exploit to verify it worked. Here's my PayPal for the bounty." Bounty? I checked my logs. Forty-seven requests to my RSC endpoint. Something, something ... Prototype pollution payloads. They used the GitHub script. The one with 2,000 stars. The one that runs id automatically "for verification purposes." They spawned a shell on my production server. uid=1001(nextjs) gid=65533(nogroup) They took a screenshot. They posted it on Twitter. "Popped a Shell on a Live Website 🚀💀 #BugBounty #CVE-2025-55182 #YOLO" They got 84781 likes. My customers' data was on that server. I asked them to delete the screenshots. They said "I removed the domain name, you should be thanking me." Thanking them. For unauthorized access to my production infrastructure. For running arbitrary commands on systems I own. For posting proof of exploitation for clout. They called it "responsible disclosure." I called my lawyer. They called me "ungrateful." I called the FBI. Now they're in my DMs explaining that "this is how the industry works" and I "don't understand pen testing." A pen what? I understand it perfectly. I understand that running react2shell-ultimate.py against random websites isn't research. I understand that "I removed the identifying info" doesn't undo the unauthorized access. I understand that #BugBounty doesn't apply when there's no bounty program. I understand that finding my site on Shodan doesn't constitute authorization. Their followers are defending them now. "Presumption of innocence." "You don't know if it was authorized." "The screenshots were redacted." Three hundred people are calling me a bootlicker for reporting a crime. Someone said I should be grateful they didn't deploy a cryptominer. The bar is underground. I just wanted to run a small Next.js app. I didn't ask to be someone's proof-of-concept. I didn't consent to being their "first" I didn't sign up for an unscheduled penetration test from a stranger with a GitHub account. There is no safe harbor for spraying public exploits at random websites. There is no legal protection for "I was just verifying the vulnerability." There is no ethical framework where unauthorized prototype pollution is a favor. But sure. Thank you for your service. You found a CVE that was already public. Using a tool someone else wrote. Against a target that never authorized you. And you posted about it on main. For likes. Hero.

Ouch. The Windows Wi-Fi driver can be exploited by an attacker that is within Wi-Fi range. It requires no interaction from the victim and no prior knowledge of the system from the attacker. Just like the movies! It affects all modern versions of Windows. Patch immediately! 👇

It is common for malware to be signed with code signing certificates. How is this possible? Impostors receive the cert directly and sign malware. In this blog-post, we look at 100 certs used by #Solarmarker malware to learn more. squiblydoo.blog/2024/05/13/i…

RE tip of the day: To obfuscate malware, attackers may introduce garbage instructions that don't do anything useful related to the actual logic or expand existing ones by replacing them with multiple others doing the same thing #infosec #cybersecurity #malware #reverseengineering

Curious about what's happening in the Windows Kernel after a Syscall? I just wrote this post following the worfkflow from the Syscall instruction to the target kernel routine ⬇️ alice.climent-pommeret.red/p… Thanks again to @Set_hyx for the proofreading!

Because writing detection rules for new emerging and #APT trends is an integral part of our work as #malware|#threat researchers, I created and cooked these #YARA rules for the initial stage dropper of the non-attributed APT group duped #DuneQuixote. github.com/Blu3Eye/detection…
