Multisig TX with multiple outputs weird error

[antonimasso]

Hello,

I created a TX where I send bitcoins from a Multisig address to a bitcoin Address and receive back the change to the same Multisig address:

0100000002b71b218f6cb6e56b7361d0c1ec712928f2c8b153b2ae569dd3b596578d4840aa00000 000fd5f0100483045022100ec789fa0a52cb94b628bc209e95391a00ea0aba3803f208e0099f806 2f0fb697022048d73d26f7cb6a3bbb523b9d0975cfe8551f8597a93ba71ecd7dec2fd37545f5014 93046022100f60c6aa402f329b14cdbdccc8c32f0f558bfa19af68ff8bd0dbc7dd3a7038fd70221 00cd250e2864a98c3685d5efc2e21d41e00e2717a1ccf1a90070e1a788bf9b1287014cc95241043 394c36007889341b06434535adbb6d9ff8d54f0a075f660f9a15c5c160bd24eb8f9bd98d32e3b66 24d1fefa360496d8a98f8ee2e558e6d0e385ff1afc2b70b741049b0ee70d754c419be928df64902 9004bbffbe1f0a3a5b60f2c5141eb4e109438b8bfb6f68776d4632bbfa9ce2646388d4f436a350f a0fa3d9fd0ecd83a63da25410491e379d32b48a0fde8e7923a41d6b2004636aabb9b47efc564770 d582e59714c8594e592fc6f17b25afbd912f0750e66a2744c73776b88f42c63fdc338d29bbf53ae ffffffff067881c00fafa2649c3fe23c5dcc599329317ebedd4fc1b8d5478ce175e5ea180100000 0fd5e010049304602210089a49da1c63d4a6de3807a5c4ae772ecfc027f0ad86e8de4bb980b6484 8bebb1022100fa1fe48805f2f5ca8c7c6bc611e17556229530c5e2d978488070213c96c7eedc014 73044022024f654097139dcc5f48a4b3031115d63c67d21cff63128b8b07ff8d366a2a8c9022002 efd03c8f1b271e5e29a6918b4f8d1f42bf26be5ee24d0c01e79c52c4b80c9f014cc95241043394c 36007889341b06434535adbb6d9ff8d54f0a075f660f9a15c5c160bd24eb8f9bd98d32e3b6624d1 fefa360496d8a98f8ee2e558e6d0e385ff1afc2b70b741049b0ee70d754c419be928df649029004 bbffbe1f0a3a5b60f2c5141eb4e109438b8bfb6f68776d4632bbfa9ce2646388d4f436a350fa0fa 3d9fd0ecd83a63da25410491e379d32b48a0fde8e7923a41d6b2004636aabb9b47efc564770d582 e59714c8594e592fc6f17b25afbd912f0750e66a2744c73776b88f42c63fdc338d29bbf53aeffff ffff02a0860100000000001976a9140c1a6c3d019c18ecacc63427d6badaeff7fedcf288acf0b31 a000000000017a914c417aaa20fd9f2693b3c3e10021848accf47707c8700000000

You can verify the script here: http://coinb.in/multisig/

The change is received correctly, but the bitcoin address receives the payment and automatically sends the bitcoins to another address:

https://blockchain.info/es/address/126zmC4XSu5nFU7bYZVwEn9iVc82MXk15B

I don't own that address and have no idea what might be the error. Any ideas on what might be the problem?

Thanks

[piotr_n]

it doesn't look like any error.

apparently, whoever knows the private key for 126zmC4XSu5nFU7bYZVwEn9iVc82MXk15B is running a service that automatically forwards all the incoming payments to another address.

your transaction is fine - the forwarding one is a separate transaction, composed and signed by someone else, not you.

Makes sense. For testing purposes I used very simple passwords to generate the bitcoin addresses. I'll repeat the test with new private keys.

Thanks

I used very simple passwords to generate the bitcoin addresses

yeah, that's probably it.
many easy keys have some bots, that capture money from them as it comes.
as well as many stolen keys - such are definitely being monitored for a potential theft and robbed immediately as they receive any coins.

I used a stronger password generated bitcoin address and now all works as expected: https://blockchain.info/es/tx/4b67dc0c6d1c909a663268673b8eea90004b1cc06663b6b2124cb4e24050e4cb
