1) Major ransomware groups and dark web presence (2025 snapshot)

• Qilin: Most active group in Q2 2025 by leak volume, capitalizing on affiliate migrations following disruption of rivals; aggressive posting cadence and broad sector targeting, including manufacturing and public sector according to multiple quarterly reviews.asec.ahnlab+1

• RansomHub: Experienced instability and actor conflict; affiliates used diverse exfil paths (Rclone/WinSCP/HTTP POST) due to limited baked‑in exfil tooling; ransom notes emphasize swift payment with leak‑site threats and clearnet mirrors for pressure.bitsight

• Medusa: RaaS with rising activity and high‑pressure double‑extortion, targeting critical infrastructure and global brands; central operators reportedly manage negotiation while affiliates handle intrusion chains.checkpoint

• Ecosystem churn: Cartels rise/fall, affiliate schemes loosen vetting to grab share, and groups recycle or rehash data to inflate leak counts—demanding rigorous validation before response decisions.rapid7+1

What this means for defenders: Focus tracking on affiliate behaviors, exfil tooling, and victim comms formats, not just “brand” names—affiliates carry TTPs across banners and leak sites.rapid7

2) Leak site architecture, operating patterns, targeting

• Architecture: Tor‑hosted blogs with victim card pages (logos, timers, partial dumps), sometimes clearnet mirrors to increase media pressure; frequent domain rotations and CDN‑style content reuse complicate simple blocklists.cyberint+1

• Patterns: Data‑only and “triple extortion” (public posting + customer/partner outreach + DDoS threats) now common; sectors: manufacturing, SMBs, and public sector remain highly exposed due to uneven patching and constrained IR budgets.commvault+1

• Targeting: IAB‑acquired footholds, stealer logs, and unpatched remote services feed affiliates; weakened affiliate vetting increases operational noise and OPSEC mistakes, occasionally exposing inner workings—useful for intel.rapid7

3) Negotiation processes and payment mechanics

• Negotiation flow: Victim portal (Tor), chat with scripted “analyst,” proof‑of‑life samples, initial high demand, timed “discounts,” PR threats; AI‑assisted copy now refines tone and speed, personalizing pressure tactics at scale.checkpoint+1

• Payment rails: Predominantly BTC/USDT; risk profiles differ: BTC is traceable with mature analytics; stablecoins add ease but touch centralized entities—enable sanctions/AML outreach where applicable.commvault

• Takeaways: Negotiation transcripts (when captured) yield indicators (wallets, operational calendars, communication templates) and reveal group SOPs—feed to SIEM/EDR detections and playbooks after legal review.splunk

4) Intelligence collection techniques for monitoring

• Sources: Leak sites, ransom notes, affiliate forums, stealer‑log shops, initial access broker listings; cross‑reference with vendor risk data and public breach disclosures for validation.unit42.paloaltonetworks+1

• Automation: Low‑and‑slow Tor collectors with per‑site throttles; capture victim cards, wallet addresses, hashes, and note text with timestamps and cryptographic hashes for chain of custody; de‑duplicate re‑posted content.unit42.paloaltonetworks

• Routing: Normalize artifacts (group, affiliate if known, sector, country, wallet, indicators) and push to SIEM/SOAR; trigger identity resets and partner notifications on verified exposures; notify legal for potential LE outreach.splunk

5) Attribution methodologies and actor profiling

• Affiliate‑centric profiling: Toolkits (Rclone, Cobalt Strike, S3 usage), exfil paths, note phrasing, timezone patterns, crypto usage, and targeting preferences are often affiliate fingerprints; track these across banners to build durable profiles.bitsight+1

• Group governance signals: Entry requirements, revenue share, negotiation centralization vs. affiliate‑handled comms, and leak site web stacks are useful for clustering and predicting future behavior.rapid7

• Confidence scoring: Use Low/Medium/High assessments for linkages and share with IR/LE along with caveats about recycled data or claimed but unverified breaches.unit42.paloaltonetworks

6) Victim impact and data exposure analysis

• Exposure triage: Identify data classes (PII/PHI, credentials, IP, financials, OT configs); estimate regulatory exposure and fraud risk; correlate with DLP, identity provider logs, and endpoint telemetry to rank urgency.ibm+1

• Supply chain blast radius: Cross‑reference vendor mentions to accelerate TPRM actions and contract notifications; use internal supply chain playbooks to coordinate containment and communication.commvault

• Decision support: Provide executives with scenario paths (pay vs. restore vs. partial disclosure response) but align with “do not pay” policies and insurer/legal guidance as paying now carries heightened legal, sanctions, and reputational risks in 2025.kaspersky

7) Proactive defense from ransomware intelligence

• Controls from intel:

  • Identity: Force MFA, disable legacy protocols, monitor for stealer‑log creds and IAB overlaps; identity session revocation playbooks tied to leak site detections.splunk

  • Data: Segment backups, immutable storage, monitor exfil patterns (Rclone/WinSCP/S3 tools) with EDR; block known tool hashes and command‑line patterns.bitsight

  • Perimeter: Patch and disable exposed admin interfaces; geofence, CAPTCHA/logon throttling; alert on abnormal archive and data transfer behaviors.splunk

• Purple teaming: Emulate exfil toolchains and negotiation timelines to test readiness; tune detections against live affiliate TTPs derived from intel.unit42.paloaltonetworks

8) Law enforcement coordination and evidence collection

• Evidence package: Full‑page captures of leak entries, ransom notes, onion URLs, wallet addresses, chat excerpts, timestamps, and hashes; maintain unaltered originals and redacted versions for internal use.splunk+1

• Coordination: Pre‑establish counsel‑led channels to share indicators, negotiation metadata, and crypto intel; understand thresholds for reporting and seizure support; avoid vigilante actions.checkpoint

• Post‑action: Track subsequent arrests/seizures and update profiles; anticipate affiliate migrations and resurrected brands to avoid blind spots.halcyon+1

9) Recovery strategies and post‑incident intel

• Restoration: Prioritize clean backup restoration with immutability checks; verify gold images; rotate credentials, keys, and tokens organization‑wide.splunk

• Leak containment: Prepare victim communications, credit monitoring, and partner notifications; monitor leak sites for promised “full dump” timelines and takedown possibilities with LE.unit42.paloaltonetworks

• Lessons learned: Mine ransom notes and affiliate toolchains for detections; update tabletop scenarios and playbooks; align with the enterprise ransomware defense blueprint for end‑to‑end maturity.splunk

10) Emerging RaaS trends

• AI‑assisted operations: Automated negotiation scripts, faster reconnaissance, and tailored extortion narratives; defenders should expect higher tempo and personalization in comms.cyberint+1

• Affiliate free‑for‑all: Looser vetting raises OPSEC mistakes but increases victim volume; defenders can capitalize on sloppy TTPs to develop signatures and arrests.rapid7

• Triple extortion focus: DDoS and stakeholder outreach amplify pressure; ensure DDoS playbooks and public comms are ready as part of IR.commvault
