Yesterday i sent some transactions to poloniex and 2 of the three transactions had been malleated. So copies were created and showed up. They didn't confirm of course.
So it's really so that 2 attacks run now. Might be from the same person trying as much harm as possible.
Did both transactions confirm eventually? How long did it take to confirm. Hope the delay did not affect your trading.

My bot is paused for a long time.
Are you sure that your original txs have low-S signatures?
Because some users malleate "non-standard" transactions to "standard" form.
https://bitcointalk.org/index.php?topic=1204959.0See, i sent 3 bitcoin transactions. I logged in now and the deposit list looks like this:
2015-10-22 18:51:39 COMPLETE
2015-10-22 18:48:21 PENDING (0 of 1 confirmations)
2015-10-22 18:48:21 COMPLETE
2015-10-22 18:47:42 COMPLETE
2015-10-22 18:47:42 PENDING (0 of 1 confirmations)
You see two transactions didn't confirm, three did. Though the two nonconfirming seems to be malleated versions of 2 of the other transactions. Same time, value and target. So that was part of the malleability attack it seems.
