| 2026-08-02 (24h) | TLP:CLEAR | 2026-08-03 |
1. Executive Summary
Yesterday’s collection comprised 23 reports, all sourced from RansomLook leak-site monitoring, making ransomware the sole theme of the reporting period. Qilin was the most active actor with seven newly named victims, while the Coinbase Cartel named four organisations with published demands ranging from $10.5M (MIM Fertility) to $500M (M. B. Kahn Construction Co.). The AI correlation pipeline elevated Gunra’s double-extortion campaign to a critical trend on the strength of two new manufacturing/hospitality victims and its known Linux variant targeting critical infrastructure. Play (Hive-affiliated, intermittent encryption) and Inc Ransom (which listed quantum-computing firm quantinuum.com) also posted fresh victims. A separate earlier correlation cycle surfaced macOS AMOS (Atomic) stealer phishing activity alongside MediaWiki deserialization flaw CVE-2026-58025 (RCE via malicious log imports). No confirmed in-the-wild exploitation of a named CVE and no CISA KEV additions appeared in this period’s pipeline data.

3. Priority Intelligence Items
3.1 Gunra Ransomware — Double-Extortion Campaign Flagged Critical
Source: RansomLook — Gunra
The correlation pipeline rated Gunra’s activity a critical trend. Gunra is an emerging group first identified in April 2025 that runs a classic double-extortion model — encrypting data and threatening publication on a Tor-hosted leak site. It has developed a Linux variant and, per external analysis referenced in the report (Trend Micro, CYFIRMA), has targeted critical infrastructure across manufacturing, healthcare, IT, real estate, agriculture and consulting in Brazil, Japan, Canada, Turkey, South Korea, Taiwan, Egypt and the U.S. Two new victims were posted on 2026-08-02: Weilhotel and Siam Stabilizers and Chemicals Co., Ltd. (SSC). Observed techniques: T1485 (Data Encrypted for Impact), T1496 (Resource Hijacking), T1567.002 (Exfiltration Over C2/Web Service).

SOC Action: Alert on creation of files named
R3ADM3.txt/R3ADM3_2.txtacross file servers and endpoints. For Linux estates, hunt for mass file-modification bursts and unexpected outbound Tor/proxy connections indicative of exfiltration (T1567.002); prioritise manufacturing and OT-adjacent hosts given Gunra’s critical-infrastructure focus.
3.2 Qilin (aka Agenda) — Seven New Victims, Highest Volume
Source: RansomLook — Qilin
Qilin, a mature Ransomware-as-a-Service operation also tracked as Agenda, was the single most active actor with seven new victims posted on 2026-08-02: The Saturday Evening Post, Commercial Furniture Interiors, Dienst Pack Systems, Ceragres, Pointe Property Group, Schreiner Trockenbau GmbH and Wire Products. Pipeline records show 2,062 all-time posts and 123 in the last 30 days, confirming sustained operational tempo despite most infrastructure showing low uptime. Associated techniques: T1566 (Phishing), T1189 (Spearphishing), T1485 (Data Encrypted for Impact), T1036 (Masquerading). Affiliate handle “Ben” is referenced in the leak-site data.

3.3 Coinbase Cartel — Multi-Sector Expansion, High-Value Demands
Source: RansomLook — Coinbase Cartel
The Coinbase Cartel RaaS named four new victims on 2026-08-02 with explicit demand figures published on its leak site: M. B. Kahn Construction Co. (Construction — $500M), Xs Cad (Architecture — $26.9M), CEN and Cenelec (Membership Organizations — $21.9M) and MIM Fertility (Healthcare Software — $10.5M). The group spans construction, healthcare, real estate, manufacturing, financial software and architecture, and communicates via Atomic Mail, Tox, Session and SimpleX. Techniques observed across the four reports: T1566 (Phishing), T1204 (User Execution), T1485 (Data Encrypted for Impact), T1071.001 (Application Layer Protocol: Web Protocols).

SOC Action: For construction, healthcare-software and membership-organisation clients, proactively check for unauthorised access and data staging. Alert on SimpleX/Session/Tox client artefacts on corporate endpoints — these encrypted-messenger installs are atypical in enterprise environments and align with this actor’s negotiation channels. Reinforce user-execution defences (
T1204): block execution from user temp/download paths.
3.4 Play Ransomware (Hive-Affiliated) — Intermittent Encryption
Source: RansomLook — Play
Play posted three victims on 2026-08-02 — The Butcher Brothers, Sigma Plastics Group and Cambridge Management — and the pipeline correlated the latter two at 0.95 confidence on shared actor (Hive-affiliates), malware (Play Ransomware) and TTPs. Play uses intermittent encryption to evade detection tools that inspect encrypted-traffic volume. Techniques: T1071.001 (Web Protocols), T1486 (Data Encrypted for Impact). Contact addresses are GMX webmail accounts.

3.5 macOS AMOS Stealer & MediaWiki CVE-2026-58025 (Earlier Correlation Cycle)
Source: RansomLook pipeline correlation batch #264 (2026-08-02 06:16 UTC)
A separate, earlier correlation cycle (batch #264) — distinct from the leak-site collection above — flagged a high-risk trend: increased targeting of macOS users via phishing that delivers the Atomic macOS Stealer (AMOS) through malicious websites, correlated (0.70) with CVE-2026-58025, a MediaWiki deserialization flaw described as enabling remote code execution via malicious log imports. The shared thread is T1204 (User Execution). Note: underlying primary-source reports and IOCs for these items were not present in this period’s report set, so details are limited to the correlation summary. No IOCs available for this item.
SOC Action: For macOS fleets, hunt for AMOS behaviours —
osascriptpassword-prompt phishing, spawning of unsigned binaries from~/Downloads, and credential/keychain access from newly executed apps (T1204). For any MediaWiki instances, inventory versions and monitor vendor advisories for CVE-2026-58025 patch availability; restrict access to log-import functionality pending confirmation.

7. Consolidated Recommendations
- 🔴 IMMEDIATE: Block the ten Qilin
dataShareexfiltration IPs (85.209.11[.]49, 188.119.66[.]189, 176.113.115[.]97/.209, 185.39.17[.]75, 185.196.10[.]52/.19, 64.176.162[.]76, 208.76.221[.]205, 185.196.8[.]92) at egress and alert on any historical connections — Qilin was the top actor with active infrastructure (§3.2). - 🟠 SHORT-TERM: Deploy detections for the ransom-note filenames across all four active families —
R3ADM3.txt(Gunra),README-RECOVER-*(Qilin),play.txt/ReadMe.txt(Play) — and prioritise manufacturing/construction/healthcare clients named in the Gunra and Coinbase Cartel trends (§3.1, §3.3). - 🟠 SHORT-TERM: Tune EDR/canaries for intermittent (partial) encryption to catch Play, which specifically uses this technique to evade volume-based detection (§3.4).
- 🟡 AWARENESS: Brief macOS users on AMOS phishing lures and inventory any MediaWiki deployments against CVE-2026-58025 pending patch confirmation; treat as watch-items given limited primary-source corroboration (§3.5).
- 🟢 STRATEGIC: Source coverage collapsed to a single feed (RansomLook) for this period — validate that Microsoft, SANS, BleepingComputer and other collectors are ingesting correctly, as leak-site-only visibility understates non-ransomware threats.
