" Within the FIRST 48 HOURS of my bot going live, on Jun 19, a whopping 9.5 BTC was transferred into an address for which I had the private key. This was approximately worth $23,000 USD at the time. I was shocked.
This is the address: 12fcWddtXyxrnxUn6UdmqCbSaVsaYKvHQp
The private key is: KzfWTS3FvYWnSnWhncr6CwwfPmuHr1UFqgq6sFkGHf1zc49NirkC
whose raw bytes are derived from Sha256 of:
16SH69WgJCXYXWV58sxjTxonhgBh5HCZTt (which appears to be some random address previously used in the chain)
BUT… I had failed to test my program sufficiently and it failed to submit the transaction! The 9.5 BTC was sitting there for almost 15 minutes before being swept away by someone else. I honestly didn’t think the first amount to cross my radar would be so high. The other samples I found from past transactions were for tiny amounts. It is quite possible that whoever moved them later out of the poisoned address actually owned them. Maybe someone else’s sweeper bot only takes small amounts most of the time to avoid attention?
At this point, I was pretty confident I was on to something not yet discovered by anyone else. I could have taken those 9.5 BTC and if this was known to others. Also, if you look into the history of that account, 12 BTC was transferred into it (and out right away) only one month earlier. No one has claimed any theft (to my knowledge) involving that address.
I fixed my program (actually tested it properly this time) and let it run again. My program detected more transactions (2 within the next 48 hours). I coded my bot to ignore anything less than .1 BTC so I didn’t move them. I didn’t want to tip off the anyone that I knew what they were doing (if that was indeed the case).
Another 3-4 days passed and the next hit my bot detected was for roughly .03 BTC (~$95USD). For some reason, this was not transferred out immediately like the rest. By this time it was July 4th weekend. I let this one sit too and it took a full 7 days before it was moved (not by me). It may have been the legitimate owner or a bot. We’ll never know.
The destination address was: 1LUqqMzaigWJTzaP79oxsD6zKGifokrh7p The private key raw bytes were: c193edeeb4e7fb5c3e01c3aebd2ec5ac13f349a5a78ca4112ab6a4cbf8e35404
The plot thickens… ——————–
I didn’t realize it at the time but that last transfer was into an address for a private key not generated from another public address like the first one. Instead, this address was generated from a transaction id! I had forgotten that I seeded my database with private keys generated with transaction ids as part of one of my earlier experiments. I didn’t label them so I didn’t know which were from Sha256(pub address) and which were from transaction ids. I found some hits at the time but when I checked the balances for those accounts, they were all zero and I didn’t think anything of it. But now my database was detecting ongoing transfers into THOSE addresses (transacton id based) too!
Okay, someone was possibly using information from the blockchain itself to ensure private keys were discoverable for the addresses they were funelling bitcoin into. The interesting thing is I found a link between the 12fcWddtXyxrnxUn6UdmqCbSaVsaYKvHQp address (via sha of a public address) AND the 1LUqqMzaigWJTzaP79oxsD6zKGifokrh7p transfer (via the tx id as a key). In the history of both of these addresses, you can see the BTC eventually ended up into this address: 1JCuJXsP6PaVrGBk3uv7DecRC27GGkwFwE
Also, the transaction id was for the previous transaction to the one that put the BTC in the toxic (discoverable) address in the first place. Now it became even more clear. The malicious code sometimes used a recent transaction id as the private key for the doomed destination address. Follow the .03 BTC back and you will see what I mean, you eventually get to the txid = private key for that discoverable address.
The 1JCuJXsP6PaVrGBk3uv7DecRC27GGkwFwE address is ONE of the collection addresses. I have reason to believe there have been many over the years. This one only goes back to approximately March 2017. You can see in the history of this one address when they consolidated their ill-gotten gains into one transaction back to themselves.
I let my bot run longer. The next hit I got was for block hashes that were used as private keys (see Experiment #1). Sure enough, this address also had links to the 1JCuJXsP6PaVrGBk3uv7DecRC27GGkwFwE collection address!
And remember my merkle root experiment? I believe those were also part of this. However, I have not linked those to this one particular collection address yet. In the end, I found a total of four different ‘discoverable’ private key methods being used.
I made sure my database was filled with every block hash, merkle root, transaction id and Sha256(public address) for private keys and let my bot run. Transactions for all four types were showing up, again for tiny amounts which I ignored. By this time, I was watching BTC getting taken in small amounts regularly. Sometimes, I saw as many as 6 transactions fly by in one day.
How fitwear lost (and got back) 9 BTC ————————————-
On Nov 12, my program saw 9 BTC transferred into an address that my database had the private key for. I had searched for that address too to see if anyone was claiming ownership but I didn’t see anything. I decided to send a small amount to a well known puzzle address to give the transaction some public scrutiny in an anonymous way (1FLAMEN6, I’m still trying to solve this BTW). Shortly after, I became aware of fitwear’s reddit post claiming theft after someone noticed the prize amount had been topped off and linked the two events together.
I contacted fitwear privately and returned their coins minus the small amount I sent to the puzzle address. Blockchain.info’s original response to his support ticket, was that his system must have been compromised. However, if you read his post, he took every precaution including typing in the key for his paper wallet instead of copy/paste and using 2FA.
In his case, in Aug 2017, he imported the private key for his 1Ca15MELG5DzYpUgeXkkJ2Lt7iMa17SwAo paper wallet address into blockchain.info and submitted a test transaction. At some point between then and Nov 12, the compromised 15ZwrzrRj9x4XpnocEGbLuPakzsY2S4Mit got into his online wallet as an ‘imported’ address.
Together, we contacted blockchain.info and I relayed the information I just outlined above to them. Their security team investigated but found no evidence it was their system that was at fault. I suppose it’s possible his system was somehow compromised back in August and managed to import a key into blockchain.info without him knowing it. Or someone else logged into his account, imported the key, then waited. I feel the malware/login explanations are much less likely because it looks like code attempting to ‘hide in plain sight’ to me. You wouldn’t need to use Sha256(address) or block hash or txid or merkleroot if you were malware or an unauthorized login. You would at least salt or obscure the key with some bit of knowledge only you know so that only you could derive the private key (as mentioned earlier). The fact that information from the blockchain itself is being used indicates it may be some transaction processing logic. Also, fitwear took extreme precautions (you can read his reddit post for details). The origin of these poison destination addresses remains a mystery.
If it’s the case that some wallet generation code is doing this, then it may be the case that we’re seeing ‘change’ transactions. When you create a wallet, there maybe 20 addresses generated. They are all supposed to be random keys. If this rogue code creates one of them in this manner (based on the public address string of an earlier one), then at some point, your ‘change’ will get put back into it as the wallet ’round-robins’ through the list.
fitwear’s 15Z address sat unused until Nov 12 when fitwear transferred his 9 BTC into it using blockchain.info.
To see the connection, take a look at this:
echo -n “1Ca15MELG5DzYpUgeXkkJ2Lt7iMa17SwAo” | sha256sum 9e027d0086bdb83372f6040765442bbedd35b96e1c861acce5e22e1c4987cd60
That hex number is the private key for 15ZwrzrRj9x4XpnocEGbLuPakzsY2S4Mit !!!
fitwear insists he did not import the key for that address. Did Blockchain.info generate it or was it added by mallicious browser code? We may never know.
See below for the complete list of other Sha256 based addresses that suffer from the same issue. I believe this is happening for others. It’s likely, that the small amounts usually taken are going unnoticed by the owners.
What does this mean for bitcoin? Nothing probably. I believe the bitcoin network itself to be secure. However, as long as humans are involved in the services that surround it (mining pools, exchanges, online/mobile wallets) there is always a chance for fraud or error. The bitcoin network itself may be ‘trustless’, but anything humans touch around its peripheries is certainly not. And you need to use those services to get in/out of the network. So even with bitcoin, it still boils down to trust.
To be fair to blockchain.info, only Sha256(public address) (one in particular) was found to be present in one of their wallets. The other 3 methods I described above could be completely unrelated. And they could all possibly be a (really weird) software bug.
Here are 100+ addresses that received bitcoins whose private keys are the bytes resulting from Sha256 of another public address. Most of these came from a scan I did of old transactions, not while my bot was running. Blockchain.info told me they do not appear to have been generated by their system.
Also, the list of addresses I”m providing are only the subset that have already had some BTC transacted through them. There are likely hundreds more lying dormant inside people’s wallets that have not been used yet.

My bot moved coins from the last two addresses only. (No one has claimed ownership from 16nX). All other transfers were the result of other people who either figured this out or are the ones who planted the bad addresses themselves (since 2014).
And these are some recent examples of private keys that are based on other information from the blockchain itself (as stated, may be completely unrelated but still happening on a regular basis).

I think this information should be made public about discoverable bitcoin private keys so that other backend systems plugged into crypto networks can guard against this sort of ‘hide in plain sight’ attack. As stated earlier, I honestly set out to look for buried treasure and stumbled upon someone else’s exploit. Thanks to yt_coinartist’s assistance in making this public. "
