Today I was in claim BitcoinCash mode, which I completed successfully with my Ledger Nano S and also with my Trezor. Then it was time to for the Bitcoins I held only in my Electrum wallet. I retrieved the private keys and set out to import one into a new BitcoinCash wallet. All bitcoins were first moved off Electrum to a different wallet on a different computer. I then installed the BitcoinABC.org wallet. When that was done I encrypted it immediately. I then used importprivkey to import a private Bitcoin key that had previously held .1 bitcoin.
The blockchain scan started. I let it run and went to lunch. When I got back, the .1 bitcoin cash had been received, but there was also a send transaction 39 minutes later to a BCC address (36uzTBVeWN2pvUu3YX22gCutovGwQg1eeS) I don't know. I didn't make the send transaction and there are no other people that could have and no computer issues, malware or otherwise on my end. Also, I had a list of other private keys open on the same computer and only issue is with the one key I imported to BitcoinABC wallet.
How was BCC sent from my encrypted wallet, where only I (and BitcoinABC wallet after importing) have the private key, if there isn't a vulnerability in the BitcoinABC wallet?
Has anyone else had this issue with BitcoinABC wallet?
Is there a BitcoinABC wallet rep on this site that can address this issue?
