scarlet: we spoke with the ceo of medsec.hat she said about her decision to approach money waters as approach to the company. the timegnize a lot of standard operating procedures are to approach the manufacturer. what we have seen, unfortunately with st. jude, is a track history of sweeping these issues under the carpet. scarlet: in the discussion of whether what her firm did was ethical, you and i have discussed earlier what tends to happen when a security researcher finds a flaw and approaches a company. , doess the usual m.o. anything get result? said is fairly common, which is companies, unfortunately, do not always react the way the public would expect them to. as you mentioned, professional, successful cyber security researchers bring them information about hacking vulnerabilities. what happens far too often is they sue the researchers. they put gag orders on them in court so that vulnerabilities cannot be disclosed. or if they accept the information, it takes a long time for them to be fixed. what medsec and carson blo

emily: medsec's ceo. cyber security experts say the actual risk of hacks against st.e patients is mostly theoretical. there have been no publicly documented cases of medical devices being hacked. to cause patients harm. pittsburgh,orget singapore is the first place in the world to achieve one important self driving car milestone. details next. this is bloomberg. ♪ emily: two stocks we're watching today. true car and autobytel plunging with big-time rivals in the car website world. amazon unveiled amazon vehicles which will feature reviews, images and specifications on thousands of car models. you can research cars on the site, you just cannot buy them there. similar to other sites, it's designed to complement amazon's other marketplaces for car parts. and singapore has beat the rest of the world in the first public trial of driverless car technology. a small group of residents there can now hail six self driving taxis with their smartphones. it is a specially designated area. a startup called nutonomy is running the trial. it is in talks with three other asian countri

carson block and justine bone, the ceo of medsec holdings will join us in a couple of minutes. we'll bring you much more as soon as we get it. let's get back to the "closing bell" exchange, especially, holly made a great point of interest rates. greg, what's the prospect for a turn in the rate environment which we haven't seen with rates moving higher? >> better today than 24 hours ago. i mean, i think the key is that for janet yellen to put a rate increase on the table in her speech and as high up as said steve is significant. i read her as wanting to get the possibility of a september rate hike on the table. it is difficult to bring themselves to increase rates if the market has that probability well below 50% on the day of. we'll still only at 30%. she is trying to get the numbers up to 50%. i read stan fischer as steve was saying, on the hawkish side of things and i recall him doing this exactly a year ago at this time of year when he put a hawkish spin on some dovish talk out of fed officials. so what i think he's trying to do is he's raising the prospect of two rate incre

scarlet: would you work with a firm like medsec? >> yes. you need to work with outside firms.att: calling it a separate security firm i find interesting -- cyber security firm i find interesting, because this was started by a former hedge fund employee, they are looking for weaknesses so they can profit off of weaknesses, like the strategy with muddy waters. do you think we could see relations born -- regulations born out of this investment or business model? >> there needs to be regulations. at the end of the day, there are no people that have not been hacked from outside sources. this is all about making stock move one way or another. and that is not the way to move the forward properly. matt: i want to read the statement from saint jude. it is important to tell you what changes is saying. the chief technology officer saying, the allegations are untrue. there are several layers of security in place. we conduct security on an ongoing basis and work with experts specifically at home and on all devices. saint jude takes the security of devices very seriously and consumer inform
