A threat actor is selling a full archive described as one of the deepest technical leaks in the field of Surface Acoustic Wave (SAW) sensors and their application in smart diapers (Smart Diaper / Wetness Sensing). The actor states the leak is not just a collection of documents but the entire intellectual core of the SAW diaper sensing project, from initial ideation through prototyping to patent filing attempts, combined with metrology archive material from Sociedade Portuguesa de Metrologia (SPMet). The dump is a ZIP file preserving the original folder structure (Documents\dms\SawTAD + SAWTAD_SRV_STO + SPMet), totalling 2.19 GB across 2,211 files.

• SAW-TAD Project (Smart Absorbent Wireless Technology for Absorbent Devices): complete R&D documentation, provisional patents, schematic diagrams, Gerber/PCB files, Arduino/ESP32 code, prototype test reports (SDP_01), and full mechanical and electrical design files
• Prior Art and Competitor Patents including EP3086116B1 (Wireless SAW moisture sensor), US20190008698A1, JP5407413B2, TWI patents, and dozens of additional reference documents on wetness sensing
• Scientific Papers and Theses: more than 20 complete papers on SAW sensors using PVDF, Quartz, AlN, GO, ZnO, flexible SAW, resonators, chemical/gas sensing, plus applications in TPMS and wireless passive sensors
• SPMet Documents (Sociedade Portuguesa de Metrologia): full archive of CONFMET conferences 2011 to 2025, abstracts (resumos), peer-reviewed articles, financial reports, scientific council meeting minutes, and metrology standards
• Patent and IP Documents: multiple patent drafts for diaper sensing systems, signed NDAs, correspondence with patent attorneys, business plans, and financial models
• Prototypes and Hardware: firmware code, RFID and SAW reader schematics, test reports, BOMs, and manufacturing files
• Presentations and Internal Documents: complete PowerPoint decks on Materials and Manufacturing, System Assembly, Medical Regulations, Investor presentations, and more
