I checked the transaction of the ltc address Lf3H5K7g6yGZGFNSd23zMZ36kvV7GkT8b3, and there was new transaction just few hours ago, idk who you're dealing with that.

The date of OP and your last transaction was last March 9 with this txid
-> c08498d6df9717994c1f25cb823daf33adf609fe7071b9bccd691ddf2a1e8f9d
But it was sent few hours later to this address, this is probably an exchange address
-> LZEjckteAtWrugbsy9zU8VHEZ4iUiXo9Nm
Upon researching it is from binance based from whale-alert.

Upon checking the old transactions, your all outgoing transaction including all in February are going to this this address LZEjckteAtWrugbsy9zU8VHEZ4iUiXo9Nm. Don't tell me that this address or your exchange account was compromised too, and still using even on your latest transaction few hours ago?
