Microsoft's stock price is surging, putting the company's total valuation at $753 billion. This makes it the third most valuable company on the planet, behind Amazon (782 billion), Apple ($923 billion) and leaving Google in fourth place, valued at $739 billion.

Karanbir Singh (a program manager at Microsoft) is on a mission:

Kill the password.

As he said in a recent blog post:

"Nobody likes passwords.  They are inconvenient, insecure, and expensive.  In fact, we dislike them so much that we've been busy at work trying to create a world without them--a world without passwords.

Do you own a Surface Book 4?  If you do, you may have been unfortunate enough to get one that suffers from a peculiar screen flickering issue.  It's not known exactly how many Surface Book 4's have been affected by the issue, but thousands of angry users have been comparing horror stories about it on various discussion forums around the web.

Microsoft has been having some "issues" of late.  It's April Windows 10 rollout had to be delayed on account of some mysterious BSOD ("Blue Screen of Death") issues. This month's rollout is plagued by similar problems, trading the BSOD issues for problems with both "Hey Cortana" and Google's Chrome browser.

Apple promised that its iTunes app would be available on the Microsoft Store by the end of 2017.  The announcement was greeted with enthusiasm, but unfortunately, the company didn't meet their own deadline. They cited the need for more time to build a more robust user experience for Windows users.

Security researcher Assaf Baharav from Check Point Security has discovered a new twist on an old, fairly well-known attack.  He was able to essentially "weaponize" PDFs to steal Windows credentials stored in NTLM hashes.  Unfortunately, no action other than simply opening the PDF is required for the hacker to gain access to the information.

Microsoft recently made small but significant changes to its Office 365 subscription service and to OneDrive, which are often used in tandem.  The goal is to make it easier for users whose files have been encrypted by ransomware (or otherwise corrupted) to recover them.

Last year's Wannacry attack was bad, but in many ways, it was a self-inflicted wound.  According Webroot's recently published "Annual Threat Report," almost all of the machines that succumbed to the Wannacry attack were running Windows 7.  That attack is estimated to have caused in excess of $4 billion in total losses.

Congratulations to Adobe Flash Player for not being the software most targeted by hackers.  Security vendor "Recorded Future" has just published their annual list of the software hackers most commonly focus on when targeting computers and handheld devices for attack.
