(SEC) fined LPL $275,000 and required that LPL strengthen its security
safeguards involving customer information. It was found that the hacker(s)
placed, or attempted to place, 209 unauthorized trades in 68 customer
accounts of several of LPL's registered representative, for
more than $700,000 in trades in securities of 19 different companies.
