New York, US, 5th July 2025, ZEX PR WIRE, Cyber Threat Intelligence Bulletin In a digital landscape increasingly shaped by supply-chain compromises and evasive malware frameworks, a new entity is quietly gaining attention: 0dayvulnerabilities.com. This low-profile, invitation-only platform claims to offer access to exclusive zero-day vulnerabilities — custom-built, undetectable, and never sold twice.
According to the site, it does not simply list vulnerabilities. Instead, it delivers private exploit chains, fully operational payloads, and infrastructure support — all packaged with stealth in mind. Each build is tailored per client and includes the option for integrated countermeasures.
Security researchers have noticed growing chatter in underground forums referencing a vendor providing “zero-trace delivery” and “undetected by any AV” payloads. The offering appears to include:
-
17+ active private 0days
-
3 new exploits monthly
-
Full infrastructure kits
-
Hardened C2 and dropper support
-
24/7 operational assistance
While the platform’s claims are hard to verify externally, it aligns with a growing trend toward closed-source offensive tooling, typically unavailable on public or darknet marketplaces.
Discussions across threat forums increasingly include queries like buy 0day, buy 0day exploit, and analysis of zero day exploit price structures in niche circles. According to open-source intelligence (OSINT), operational-grade exploits—particularly for platforms like Android, macOS, and Windows—can fetch six figures, especially when pre-auth RCEs are involved.
One testimonial allegedly from a threat actor group claims a successful breach of a Tier 1 fintech platform using tools sourced via the site. While the source can’t be verified, it aligns with the platform’s claim that their tools are “real-world tested payloads” used in stealth campaigns.
“This is not your average leak site. It’s a structured offensive toolkit service — with full support and zero visibility,” said an anonymous operator in a private channel.
Unlike marketplaces focused on noisy proof-of-concepts, 0dayvulnerabilities.com presents a cleaner, quieter model. With a strict no-resell policy and individualized exploit kits, it positions itself in contrast to noisy commodity brokers. For those looking to buy exploit 0day in a format ready for immediate deployment, this approach marks a distinct shift from the traditional threat economy.
Whether this closed vendor is a flash in the pan or a long-term player remains to be seen. But as demand for advanced persistence and undetectable RCE grows, so too does interest in truly private tooling — even if it comes at a premium.
