I believe my Vert wallet I got is hacked.  The balance that shown on wallet is different from the published blockchains.

The wallet reported less than actual amount for the sake of sending out units to secret address not shown in wallet but showing in blockchains.

The method the wallet hacked is simple.  When it started up, it create a address for use until next restart.

When I send out certain units, the hidden units is sending out to these theft wallet address.  I believe it works on miners wallet when you never counter check the wallet balance and the actual balance in blockchains.  It started with small amount until the % grown to 10%.  It was hacked for almost more than a week.

Always check the blockchain using vertcoin block explorer.  i believe this kind of theft in real world happens but only BitCoin ptotocol like this can trace this problem.
