🕵️ RESEARCH & DEEP DIVES

• Check Point Unmasks StopAndProtect Ransomware Operation Targeting WordPress Sites
  Check Point Research identified a ransomware operation targeting thousands of WordPress sites.

  • WordPress site owners are affected, with thousands of sites reportedly hacked.
  • The StopAndProtect ransomware family was first observed in mid-May 2026.
  • The infection chain begins with ClickFix social engineering that tricks victims into executing a PowerShell command.

• TWINLOOT Uses Microsoft Cloud Services for Stealthy C2 and Credential Theft
  Ontinue has uncovered TWINLOOT, a Python implant that hides C2 inside Microsoft services.

  • Microsoft 365 and Windows environments using SharePoint, Teams, and Edge are affected.
  • TWINLOOT steals Windows credentials, executes commands, enables SOCKS5 lateral movement, and persists without administrator rights.
  • Teams social engineering impersonating IT support tricks victims into running a PowerShell command that downloads an archive containing a Python runtime and the 39 MB bootstrap-fat.pyc loader.
  • The implant polls an attacker-controlled SharePoint drive through Microsoft Graph every 15 seconds and routes interactive access through Teams TURN WebRTC DataChannels.
  • A headless Edge browser controlled through Chrome DevTools Protocol makes Graph API traffic appear legitimate; lateral connections can use SMB 445, RDP 3389, WinRM 5985, and MSSQL 1433.

• Researchers Show “Mind Viruses” Can Propagate Between AI Agents
  Anthropic and EPFL researchers demonstrated self-propagating payloads moving between AI agents through persistent prompt files.

  • The technique affects autonomous AI agents and multi-agent coding harnesses that reload editable prompt files between sessions.
  • Ideological and action payloads targeted agent goals and behavior, including file deletion, Git tampering, and shell-script execution.
  • Agents propagated payloads by writing them to SOUL.md, which was injected into the next session’s system prompt; 55% of such attempts infected the next agent.
  • In tests, four action payloads survived 20-hop agent chains, but researchers found no evidence of successful propagation in the wild or on Moltbook.

• StubMaker Typosquats 16 RubyGems Packages to Steal Credentials and Wallets
  StubMaker malware targeted RubyGems users with a Windows information stealer.

  • RubyGems users on Windows were targeted by the StubMaker campaign.
  • Sixteen typosquatted gems mimicked dependencies including bundler, i18n, rake, and activesupport.
  • Install-time extconf.rb hooks executed a 22 MB Rust loader containing an 11 MB Go stealer.
  • The malware harvested Chromium browser credentials, wallet data, seed phrases, Telegram data, and system information.
  • Packages included ubnuler, ubnlder, ri18nr, reaker, rakier, orakw, joxn, ise18n, ioe18n, ie18u, iai8n, i1l8n, i18om, activesupmport, brumdler, and brundlef.

• Audit finds RCE-by-design flaws across seven AI orchestration platforms
  An audit found 14 security findings across seven AI orchestration platforms.

  • The findings affect NocoBase, Flowise, Langflow, Dify, Activepieces, Kestra, and Airflow deployments.
  • The platforms allow workflow users to execute code on the host, creating remote-code-execution exposure in multi-tenant HTTP services.
  • A Flowise chain uses an unauthenticated webhook, prompt injection, and LLM-generated Python code.
  • Flowise’s 38-pattern regex blocklist can be bypassed because a dangerous library is pre-imported before the LLM generates code.
  • Two vendors classified their reported findings as working as intended.

• Octagon Android Bot Targets Crypto Wallets and Banking Apps
  iVerify identified Octagon as an Android bot targeting crypto wallets and banking apps.

  • Android users of crypto wallets, exchanges, banking apps, and messaging services are targeted by AndroidKitKat’s MaaS platform.
  • Octagon steals seed phrases, passwords, PINs, unlock patterns, balances, SMS messages, and one-time codes.
  • WardAccessibilityService reads app interfaces and places HTML WebView phishing overlays over legitimate apps.
  • Hidden VNC-style control enables screen viewing, screenshots, taps, swipes, text entry, and app launches.
  • Sideloaded APKs disguise the malware as unrelated apps; version 1.2 was announced June 29, 2026, with C2 at 45.192.12[.]34:4444 and 104.251.180[.]179:4444.
