Dyn is an internet performance management company and when things are going well, we don't hear anything about them. That's good, but that was not the case on Friday.

The company is being hit with a distributed denial of service (DDOS) attack on Friday. It's led to outages for high-profile sites such as Netflix (NFLX) - Get Netflix, Inc. (NFLX) Report , Amazon (AMZN) - Get Amazon.com, Inc. Report , Twitter (TWTR) - Get Twitter, Inc. Report , Spotify, Reddit and others.

The Department of Homeland Security is looking into the attacks, but very little information is currently known about it. The attacks hit twice, rendering these sites unavailable for a short period for many users throughout the U.S.

Some have speculated that the attacks are just practice, and the real hit will come closer to the election.

Of course, that's speculation. But the threat of cyber-terror is very real and Friday's events only highlight what could happen. Investors need to consider the impact that these types of coordinated attacks could do to our nation. It's not just about orders with Amazon or a streaming shows on Netflix either.

Logistics and health care rely on the internet. A whole slew of jobs and entire industries rely on it. Our 21st century is arguably built on it. So with cyber terrorists running rampant throughout the intangible world, investors need to be aware of the situation, and so do companies.

Hopefully by Monday this is more sorted out, and people start to take cyber safety a bit more seriously.

We've all read about how the flammable battery in the Samsung (SSNLF) Galaxy Note 7 has been so detrimental to the company's business. Well, now rumors have popped up about Apple (AAPL) - Get Apple Inc. (AAPL) Report .

The Cupertino, Ca.-based tech company is investigating reports that an iPhone 7 caught fire in Australia. As it goes, the users wrapped his phone in his pants and placed it in the car when he left for a surf lesson. When he got back, the car was filled with smoke, his jeans were on fire and his phone was "just melting inside."

While this certainly isn't good news for Apple, the company can at least sleep tight knowing that up until now, this hasn't been an issue. It's still not entirely clear that the phone actually caused the fire, but to some it appears that way.

Should this be a one-off event -- after all, Apple makes millions upon millions of iPhones, something is bound to go wrong, right? -- the company will be fine. But additional reports of a flammable phone could hurt Apple even more than Samsung, considering how much business the iPhone generates for Apple. This is especially true if a recall were to materialize.

Given Apple's notoriety for high quality devices though, we should give them the benefit of the doubt for now.

Shares of Apple closed at $116.60 Friday, down 0.4%.

Shares of Microsoft (MSFT) - Get Microsoft Corporation (MSFT) Report closed at a new all-time high of $59.68 on Friday, surpassing their previous high of $58.72 in December 1999.

New 52-week highs haven't been uncommon in the tech sector, especially among big stocks like Facebook (FB) - Get Facebook, Inc. Class A Report and Amazon. And Microsoft wasn't an exception; it too was making new annual highs.

However, the company had long been sitting in the shadow of the all-time highs it made during the dot-com surge in the late-1990s and early 2000's. That changed on Friday though.

While the stock ultimately closed below $60 on the day -- at $59.66 -- it still gained more than 4% after the company beat on top and bottom earnings line estimates.

Gains in the cloud and an update that it expects its $26.2 billion acquisition of LinkedIn (LNKD) to close in the second quarter all contributed to the stock's gain on the day.

Of course, its buyback and 2.6% dividend yield probably add to the appeal, but it's clear that CEO Satya Nadella has taken Microsoft from a boring, old-line tech stock to a new, albeit not outrageous growth stock.
