Introduction
This chapter presents the immutable, verifiable facts of the event as recorded on the Bitcoin and Bitcoin Cash blockchains. It serves as the empirical foundation for all subsequent analysis, establishing a clear timeline and cataloging the digital artifacts left behind by the actor.
🔍 Forensic Principles
Every hypothesis and conclusion that follows is grounded in this on-chain evidence. The immutable nature of the blockchain guarantees that this data cannot be manipulated.
1.1 Anatomy of the Event: A Chronological Reconstruction
The operation was not a singular, instantaneous action but rather a methodical, multi-stage process executed with precision across two different blockchains. This timeline reveals a level of planning and operational security far beyond that of a typical user or even a standard institutional transfer.
Initiation - BCH "Test" Transaction
Bitcoin Cash Test Transaction
Time: July 4, 2025, 02:41:32 UTC
Amount: 10,000 BCH
Source: 12tLs9c9RsALt4ockxa1hB4iTCTSmxj2me
The first overt action occurred not on the Bitcoin network, but on Bitcoin Cash (BCH). This allowed the actor to perform a low-cost, low-visibility "canary" test to verify that the compromised private key was functional.
Main Event - Coordinated BTC Transfers
Major Transfer Initiation
Time: July 4, 2025, 03:43:33 UTC
Total Amount: ~80,000 BTC
Number of Wallets: 8
Over the following hours, approximately 80,000 BTC was systematically drained from eight separate legacy Pay-to-PubKey-Hash (P2PKH) wallets. Each of these wallets had been untouched for over 14 years, remarkably holding uniform amounts of approximately 10,000 BTC each.
Destination - Security Upgrade Appearance
Transfer to Modern Addresses
Target Format: Native SegWit (bc1q...)
Source Format: Legacy P2PKH (1...)
Crucially, the 80,000 BTC was not sent to known cryptocurrency exchange deposit addresses, which would have indicated immediate selling intent. Instead, the funds were moved from legacy P2PKH addresses to new, modern Native SegWit addresses.
1.2 Blockchain Graffiti: Analysis of OP_RETURN Messages
A central component of the operation was the strategic use of the OP_RETURN opcode. This feature allows for the embedding of small amounts of arbitrary data into a transaction, creating a public and immutable message on the blockchain.
Message Sequence and Content
Claim
"LEGAL WARNING: We have taken ownership of this wallet and its contents"
Transaction Hash: 4f7c80c05fd77a9c9b180f7f6400560d1ab6cf3a4ba1b6bf7429eeeefa500a05
This message was a bold and aggressive legal declaration. It demonstrated the actor's confidence and intention to frame the operation within a legal context.
Ultimatum
"Not abandoned? Prove it by September 30th with an on-chain transaction using the private key"
Transaction Hash: e511f90160b2f189eaf0adce7221979cbc9001bc29e6c5476914d002a9d19886
This message dared the owner to use their key, the only form of proof that matters on the blockchain. It underscored the demand for cryptographic evidence.
Legal Appearance
"OWNER WARNING: see salomonbros.com/owner-notice"
Transaction Hash: ba9958bca2ae46e5fdea8737fef02bca6cfe1723196917699a058c30b6f52fd8
The third message professionalized the operation by directing observers to an external website. An effort to create an appearance of legal legitimacy.
Cryptic Signature
"4 8 15 16 23 42"
Transaction Hash: ac35cc92a1d97298c7b2a89e1f8260da61d0447c28927585baecd2bfa863aec0
The final message used the "Lost Numbers" from the television series Lost to mystify the crypto community. A cultural reference associated with themes of fate, control, and hidden knowledge.
💡 Analysis Result
This sequence was not random. It was a carefully orchestrated performance that created a multi-layered narrative designed to confuse observers and control the story, blending legal intimidation with cryptic popular culture.
1.3 The "Salomon Brothers" Facade: Archive and Domain Analysis
The reference to "salomonbros.com/owner-notice" in the third OP_RETURN message was not arbitrary. It directed observers to a meticulously crafted website that appeared to be an official legal notice from a financial institution.

📊 Summary Statistics
Conclusion
The on-chain evidence presents a clear picture of a sophisticated, multi-stage operation that was carefully planned and executed. The combination of OP_RETURN messaging, fake legal infrastructure, and systematic asset movement suggests an actor with significant technical knowledge and operational security awareness.
This forensic foundation now enables us to examine the competing theories about who was behind this operation and why it occurred when it did.
