Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.

According to tech support site BleepingComputer, victims can "trick" the program into shutting down: once they reach the PayPal purchase screen, they can hit Ctrl+O to open a dialogue box, and then enter http://hitechnovation.com/thankyou.txt. This makes the program think they've paid the $25, and it shuts down.

UpGuard's cyber risk analyst, Chris Vickery, discovers 198 million US voting records in an Amazon S3 bucket freely available online. One particular spreadsheet also calculates the voters probabilities for situations such as "how likely you are to have voted for a certain presidential candidate". This breach is another reminder of how important personal data security is.
A recent post by Brian Matis motivated me to make this alternate post to see what sort of reaction others might have about these recent revelations.
A recent article on The Verge claims that "The older operating system was less vulnerable that anyone expected"
Windows XP computers were mostly immune to WannaCry
Another article from the same source claims "Windows XP was ‘insignificant,’ researchers say" with regards to helping the WannaCry outbreak spread.
"Almost all WannaCry victims were running Windows 7"
Lots of folks (from their perspective) with a genuine need to keep running on Windows XP suffered a lot of grief in Tech forums as being one of the root causes of giving WannaCry a platform to spread and thrive from, yet now it appears all the criticism may have been a little premature and unjustified.
For the record, I personally don't condone anyone using unsupported operating systems and actively encourage everyone I deal with to get themselves up to date, but I am also sympathetic to those who feel they have a genuine need to do that, so also think they shouldn't be …

We have too many XP computers at my institution (some with only SP2) - mostly due to budgets and instrumentation.

Hi Thomas,
Have you considered purchasing an XP Updates agreement with Microsoft? Might be an easier solution if budget restraints prevent you from upgrading? I wouldn't feel comfortable with a lot of XP machines in an environment as it would be a case of when, not if, it will come back to bite you. Patches are available, just at a cost.
Incidentally, SP3 for XP is still provided by Microsoft - why not install it?

NYS 20th Annual Cyber Security Conference
I will be attending this conference in Albany, N.Y. this Wednesday and Thursday. If you are going to be there, ley me know (maybe we can meet).
Over the years I have become more involved in security related areas of information technology. I hope to learn more/ keep up to date by attending this conference.

That sounds great, Thomas! I'm a huge fan of the Socratic method (to the point where I get worried some people may try to poison me one day... j/k ;-) And thinking strategically about anything can be quite a challenge, but an increasingly important one as more and more of the tactical type work is moving entirely into automation.

My summary of the 20th Annual New York State Cyber Security Conference & 12th Annual ASIA conference
The conference as a whole was very interesting, although if one has to make a choice between this one and some others, you may want to check out the others. This conference is aimed mainly at government agencies. So it addresses the various compliance issues with which they have to deal. If those do not apply to you, this conference may have limited application as well.
I did enjoy putting some faces to people I had only corresponded with. I also wanted to hear as much as possible about ransomware (these presentations turned out to be only okay), and cryptography (not a gripping presentation – it was a presentation of thesis work and ongoing research – but nonetheless very interesting). They did a good job of setting you up for the days events with a decent Keynote speaker. The lunch speakers were not as polished, but did have good things to say.
I enjoyed going around to the vendors , even if their swag was not class A stuff. (some had excellent stuff while others had none – the full gamut)
I have to say again that the highlight of the conference, for me, was the very non-technical, and only slightly security related talk by Christie Struckman of the Gartner Group, session 4 on the first day. I would encourage anyone in a leadership position to check it out. I have asked for her slides and will try to make a pdf of them available if she is amenable to that. My takeaway on that talk was: There are leaders and there are Bosses. The leaders help their teams think about solutions and then make decisions, the bosses make decisions and tell their teams to carry them out. I think the quote she used at the beginning was excellent:

"Microsoft has done the right thing by making the patch available even for older, unsupported systems. But it shouldn't proactively push out the patches, as there are usually some business reasons why companies are still running old and unpatched systems," he said.
"By forcefully pushing a patch, it could do just as much harm, causing systems and applications to become unreliable."

A 700% increase in malware (yes, you read that right) is not cool for us Apple Geeks, "The McAfee report said there were 460,000 malware instances affecting the Mac OS in the fourth quarter of 2016, an over 700% jump from the previous year during the same quarter."
Great Scott!
Alright, that was an 80's interjection but I still used it right through the 90's (I'm a geek, so give me a break). ;)
I do remember the Zip Drive (one is lurking somewhere in my attic).
Touching upon your story, that's pretty awesome! Finding Mac malware back then would have been like finding a golden Easter egg containing Willy Wonka's golden ticket (I know it was a candy bar and not an Easter egg, lol), or the ever elusive star on the Native American's bow and arrow on the Tootsie Pop wrapping. Remember when you could turn those in for another Tootsie Pop?
During your travels did you happen to run into an old TRS-80? Besides the Apple II, I loved/hated that old monchrome beast.
All of this said, you make a good point in that malware for Macs has always been around (albeit in smaller numbers).
Now I have Huey Lewis & The News stuck in my head. Thanks Brian! Lol. Hip to be Square!
