Published file metadata, source observations, indicators, and research history in one bounded catalog.
Sources represented on this page. Publication and observation dates describe the content; successful batch dates describe local collection. A recent batch does not certify complete coverage or current provider availability.
1 sources: 0 stale, 0 needing attention, 0 paused, 0 unverified.
Stale means older than twice the recorded collection interval, with a minimum of one hour; without an interval, the threshold is 24 hours. Cached content remains available while a feed is stale, paused, or unverified.
GreyNoise observed 400+ IPs exploiting multiple SSRF vulnerabilities across various platforms, with recent activity concentrated in Israel and the Netherlands.
First reported Mar 11, 2025 00:00 UTCCatalog metadata updated Oct 14, 2026 17:37 UTCOpen evidence recordGreyNoise is already seeing opportunistic, largely automated exploitation attempts consistent with the newly disclosed React Server Components (RSC) “Flight” protocol RCE—often referred to publicly as “React2Shell” and tracked as CVE-2025-55182.
First reported Dec 05, 2025 00:00 UTCCatalog metadata updated Oct 14, 2026 17:37 UTCOpen evidence recordGreyNoise has discovered previously undisclosed zero-day vulnerabilities in IoT-connected live streaming cameras, leveraging AI to catch an attack before it could escalate.

First reported Oct 31, 2024 00:00 UTCCatalog metadata updated Oct 14, 2026 17:37 UTCOpen evidence recordAttackers route malicious traffic through ordinary home internet connections — and to a reputation feed, the source IP is indistinguishable from a legitimate user's connection. GreyNoise analyzed 4 billion sessions over 90 days and found that 39% of unique IPs targeting the edge come from residential address space. 78% vanish after just 1–2 sessions, before any reputation system can flag them. The report documents why detection must shift from where the traffic comes from to what it is doing.
