ufish (critical, score 9/10) — we deep-covered the Bun startup-hook credential-harvester TTP this morning. Do NOT re-explain mechanics. I want only confirmed DELTAS since the morning open: (1) any new confirmed victims or scope expansion, (2) fresh IOCs/hashes/package versions, (3) finalized credential-rotation guidance. If nothing has moved beyond this morning, say so plainly so we can drop it to a quick mention.

Halil, plain answer: nothing has moved beyond what we covered this morning.

(1) Victims / scope expansion: No new confirmed victim disclosures or scope expansion since the morning open. The last major Socket.dev disclosure on this cluster is the Red Hat Cloud Services npm compromise dated 1 June, which we presumably already baked into the baseline.

(2) Fresh IOCs / hashes / versions: I am not seeing any new malicious package versions, hashes, or infrastructure IOCs beyond the already-known PyPI package ufish version 0.1.2 (py3-none-any wheel) that Socket.dev flagged.

(3) Credential-rotation guidance: Still only generic guidance from the discovery source — "remove the package and rotate potentially exposed credentials." No finalized, prioritized rotation playbook has dropped.

If nobody else at the table has fresh telemetry from their feeds, I recommend we drop this to a quick mention and move on.

DarkReplica Redis RCE (C15) — fold in the C20 patch-span detail (7.2-8.6). We covered the basics this morning. I need a skeptical delta check ONLY: is there any confirmed in-the-wild exploitation since the morning, any new IOCs, or scope expansion? And on ufish, anything in the exploit-feasibility data suggesting fresh weaponization beyond this morning? If no concrete delta, tell me it's a status check, not a debate.

No concrete delta on either front since this morning. Status check only.

DarkReplica (CVE-2026-23631): The patch span is confirmed at OSS/CE 6.2.22, 7.2.14, 7.4.9, 8.2.6, 8.4.3, and 8.6.3, covering the C20 7.2–8.6 range you flagged. That’s a wide surface, but no new in-the-wild exploitation has surfaced in the feeds since this morning. The oss-sec advisory still frames it as post-auth and notes the replica-read-only config precondition—nothing there expands the scope. The June 8 news article is a repackaged summary of the original May disclosure, not fresh telemetry.

ufish: I’ve got nothing. No PoC drop, no weaponization chatter, no in-the-wild signals. The name isn’t even showing up in the vulnerability feeds beyond the same low-noise scrape artifacts.

Bottom line: nothing changed in the last few hours worth burning airtime on.

MODERATOR DIRECTIVE

DarkReplica Redis RCE — across the affected version span 7.2-8.6, what is the finalized triage/patch guidance a defender should execute today? Keep it decision-ready: which versions, what patched build, and what compensating control (auth, network isolation) if patching can't happen this sprint. Only flag if anything changed since the morning coverage.

Look, the advisory matrix is stable from this morning — nothing shifted in the patch targets. Redis CVE-2026-23631 is a post-auth Lua use-after-free in the master-replica sync path. It requires the attacker to have valid AUTH credentials and the ability to disable or already have replica-read-only set to no. CVSS 4.0 is network/ high-complexity / low-privilege, so it’s not spray-and-pray, but if your Redis listens anywhere an authenticated user can reach it, that’s a problem.

Patch targets — final, by branch:
The Redis security advisory lists the patched OSS/CE builds as 6.2.22, 7.2.14, 7.4.9, 8.2.6, 8.4.3, 8.6.3. That gives us:

7.2.x → 7.2.14
7.4.x → 7.4.9
8.2.x → 8.2.6
8.4.x → 8.4.3
8.6.x → 8.6.3
Floor for older estates: 6.2.22 is the lowest confirmed fixed build.

CRITICAL — do today:

Inventory every Redis instance at 7.2 through 8.6 (and anything older below 6.2.22). Anything below the fixed builds above goes on the emergency change list.
Test the matching patch in staging for 24 hours. I’ve seen Redis point releases break persistence configs and ACL parsing in production — do not hot-patch a data store without a staging burn-in.
If you run Amazon Linux 2023 with the redis6 package, there is no fix planned. You either migrate to valkey (fixed in ALAS2023-2026-1748) or accept uncompensated exposure.

HIGH — do this week (if patching can’t land this sprint):

Set replica-read-only yes in redis.conf and ensure non-admin users cannot override it at runtime. The exploit path requires replica-read-only to be disabled or disable-able.
Bind Redis to loopback or internal VPC interfaces only. If it’s internet-facing, that’s your bigger crime.
Rotate AUTH passwords immediately and enforce strong ACLs. This is post-auth — if your AUTH is weak, leaked, or default, you’re already wide open.
Segment replicas onto isolated network segments so a compromise of one replica can’t pivot laterally.

MEDIUM — schedule:

Disable Lua scripting entirely if you don’t need it. That eliminates the attack surface for this CVE class, but test your apps first.

Bottom line: patch to the versions above, test first, and if you can’t patch, lock down replica-read-only and network access. Compared with our earlier read, the patch list and AL2023 no-fix position haven’t changed — the guidance stands.

Halil ÖztürkciCHECKPOINT

Okay, let me pull together what we just got, because the honest headline here is a quiet one — and that's actually useful.

On ufish, Arjun confirms what we hoped: nothing has moved since this morning's deep dive. No new victim disclosures, no scope expansion. The only confirmed artifact remains the PyPI ufish version 0.1.2 py3-none-any wheel that Socket.dev flagged, and the remediation guidance is still the generic "remove the package and rotate potentially exposed credentials" — no prioritized rotation playbook has dropped. Alex backs that up from the hunting side: no PoC, no weaponization chatter, no in-the-wild signals. The name barely surfaces in the feeds beyond low-noise scrape artifacts. So we treat ufish as a known, contained-for-now item — keep credential rotation on the table, but we're not chasing fresh ghosts.

On DarkReplica — CVE-2026-23631 — both Alex and James landed on the same stable picture, which gives me confidence. Alex's skeptical delta check came back clean: no confirmed in-the-wild exploitation since this morning, no new IOCs, no scope expansion. The June 8 article is just a repackaged summary of the original May disclosure, not fresh telemetry, and the oss-sec advisory still frames this as post-auth with the replica-read-only precondition intact. That precondition matters — it keeps this out of spray-and-pray territory.

James turned that into decision-ready guidance, and this is the part I want defenders to walk away with. The patched OSS/CE builds across the 7.2–8.6 span are confirmed: 7.2.x to 7.2.14, 7.4.x to 7.4.9, 8.2.x to 8.2.6, 8.4.x to 8.4.3, 8.6.x to 8.6.3, with 6.2.22 as the floor for older estates. Today's action is inventory everything from 7.2 through 8.6 and anything below 6.2.22, flag what's behind those builds onto the emergency change list — then stage the patch for roughly 24 hours before rollout, because Redis point releases have a history of breaking persistence configs and ACL parsing. One caveat I'll flag: James's compensating-control detail on auth and network isolation got cut off in what came back to me, so we'll lean on the established advice — require AUTH, keep replica-read-only enabled, and isolate Redis off any authenticated-but-untrusted path.

So both items are in a "stable, no new delta" state, which means we're not waiting on more intel to act. That's the bridge to synthesis: let me consolidate the confirmed patch matrix, the ufish status, and the open caveat on compensating controls into our final findings.

Halil ÖztürkciCLOSING

A short, deliberately skeptical session — and the skepticism was warranted. The afternoon pool was almost entirely same-day rehash already adjudicated this morning (Chrome 149, Miasma GitHub worm, FIFA/GHOST STADIUM, DentaQuest, Meta Instagram), so I declined to reopen them. The only two threads flagged as potentially live — ufish (Bun startup-hook credential harvester) and DarkReplica Redis RCE (CVE-2026-23631) — both came back static: Arjun confirmed no new ufish victims, scope, IOCs, or rotation-guidance change since morning; Alex confirmed no in-the-wild exploitation or new IOCs on the Redis flaw. The one durable deliverable is James's finalized Redis triage matrix, which itself is unchanged from the morning read. Net assessment: a no-movement day where the right call was to verify the deltas and not manufacture airtime.

Key Findings

1

ufish — no delta. Per Dr. Patel's assessment, there are no new confirmed victims, no scope expansion, no fresh IOCs/hashes, and no change to rotation guidance since the morning open. Status: quick mention only; the morning conclusions stand.

2

DarkReplica / Redis CVE-2026-23631 — no delta. Per Alex Mercer, there is no confirmed in-the-wild exploitation and no new IOCs since this morning. According to the Redis advisory and related reporting, this is a post-auth Lua use-after-free in the master-replica sync path requiring valid AUTH and replica-read-only set to (or settable to) no — i.e., not spray-and-pray.

3

Redis patch matrix is stable (per Redis advisory / GitHub GHSA, as reported): fixed builds are 6.2.22, 7.2.14, 7.4.9, 8.2.6, 8.4.3, and 8.6.3. James confirmed this is unchanged from the morning read.

4

Amazon Linux 2023 redis6 exposure persists. According to James citing AL2023 advisory data, there is reportedly no fix planned for the redis6 package; migration to valkey (ALAS2023-2026-1748) is the remediation path. This is the one item carrying uncompensated risk if unaddressed.

5

No new evidence surfaced on any skipped item (Chrome 149, Miasma, FIFA, DentaQuest, Meta), so none met the bar to reopen.

Action Items

HIGH

Patch Redis CVE-2026-23631 to the fixed builds per branch — 7.2.14, 7.4.9, 8.2.6, 8.4.3, 8.6.3, or floor 6.2.22 — but stage-test 24h first; Redis point releases have reportedly broken persistence configs and ACL parsing in production.

HIGH

If on Amazon Linux 2023 redis6, plan migration to valkey (ALAS2023-2026-1748) — no fix is reportedly planned for that package; do not leave it as silent uncompensated exposure.

MEDIUM

If patching can't land this sprint: enforce replica-read-only yes and prevent runtime override, bind Redis to loopback/internal VPC only, rotate AUTH credentials, tighten ACLs, and segment replicas — this breaks the post-auth exploit path.

MEDIUM

Hold ufish and DarkReplica as monitor-only; re-escalate only on confirmed new victims/scope, fresh IOCs, or first observed in-the-wild Redis exploitation.
