KB3201860 Adobe Flash?

So I did not install Adobe Flash, it is not in my add remove programs, nor is it any active plugin for my installed web browsers.

On this machine, I have Windows 8.1, the Flash options in control panel, but no Add/Remove for flash. I was legit baffled seeing this update pop up, as I didn’t install the software, because I feel it is more harm than good, as a security exploit vector.

KB3201860 details @ Microsoft. I am still digging around but I am really concerned how something I didn’t install is on here. I guess it will be an interesting weekend, finding this and gutting it out of this system. I also see no Adobe windows services installed.

I have heard and seen Google Chrome has it’s own version of Flash. But it adds extra concern it’s escaping the Chrome ‘sandbox’ because if you can make a call to it, it can be exploited. IMO and all of that.

Oh wow, the plot thickens. Thanks to adobe’s link, it is rolled in with Windows 8.
Checking with this Installed Flash web tool, Chrome of course has Flash baked in, as it’s baked into Chrome. My installed Mozilla based browsers fail the test (yay). IE 11 on Windows 8.1 also has it’s baked in Flash. It looks like that is what this update is for. Now of course, is the quest to eviscerate it from being able to execute or be invoked.

… So then I checked again and saw Shockwave Flash Object in Internet Explorer Add-onsand was able to disable the plugin, then the ‘Is this installed’ check failed.

Computer news recap

So everyone has been foaming at the mouth about the Dyn DNS attack / mirai botnet theory on how some large sites had been down over last Friday (10/21/2016) into the weekend for some folks. There were heat maps of areas in the USA hit, and laughably common, Russia was the 1st to blame. That of course turned into more competent speculation that the attack came from a botnet of devices, such as cameras and other Internet of Things (trash) with default passwords, or worse yet hard-coded passwords.

Pardon the cynicism, but I am waiting for this coffee to cool down and it’s the morning. I would also make a list of major websites that had their user databases taken, but that would be a huge and no where near complete list. When that happens, the obfuscated passwords are run against some cracking methods to get the raw ASCII value.  Hashcat is something I do not yet have experience with, but would like to setup a test windows domain to reverse the AD password obfuscation, for sake of seeing it run and deliver personally.  I enjoy projects.

Notable sites where the user data got popped are (with some speculation on my part, perhaps):

  • Yahoo
  • Hotmail
  • LinkedIn
  • AshleyMadison
  • MySpace
  • Twitter (~2014)
  • Facebook (~2013)

 

Please note that Twitter and Facebook are speculation on my part and that is why I put the projected date next to it.  At this point honestly, I give consideration that every site has potentially been popped for their user databases.  Salting and Hashing your user passwords will get you so far, but like encryption, if you leave the keys with the protected data… you are not really gaining any benefit because you gave away the key to the puzzle.  We can call this security nihilism, but seriously this is worth restating.  Do not store private keys with your data, if you salt and hash method are in that production database, you are going to have a bad time.

*Sips Coffee* There is no such thing as perfection, so do not worry about chasing that dragon.  The moral of the story above however, is to not re-use passwords.  Do you have the same password for your email, bank, work, and social network sites? Please don’t do that.  It makes being a victim way easier, especially after a data breach / password dump from a major site.  Let me assure you I’m not spouting this out from my ivory tower, because I had some shared passwords between services too.  Fortunately I seem to have changed those before the accounts could get popped.

Granted, depending on how bad a network gets run, authentication could be irrelevant because an attacker had full access to the site by side-stepping authentication completely.  Another one of those theories, but yeah you have to do what you can.  I spend a formidable amount of time reading about security news and researching myself.  A few years ago I dorked around pretty heavy on facebook, laughed at the perceived privacy controls, and got put in ‘Facebook Jail’ a few times for abusing features.  That taught me the humor of what privacy means, to a site that really wants to sell me t-shirts and crawl the search history on my mobile phone to schlep advertisements, if I use their mobile application.

Wrapping this up with some dystopian nightmare, I see more and more corporations are merging on up into massive conglomerates.  It feels like only yesterday Time Warner and Comcast merged, yet AT&T is preparing to buy Time Warner.  By Time Warner I mean more than just the cable services as well.  So much for reasonable internet prices.  I mean it’s pretty clear that balanced media reporting is a relic of the past, short of some slivers of the internet and print sources.  Complaining about the media, I reference the fault that comes from major networks only reporting from one perspective, so conservative hones in on their pitch, while moderate or whatever you call Fox and not CNN, also ignored highly relevant details, so they can pitch their sponsors agenda.  Worst of all, leading people to argue about disinformation they get from controlled outlets, instead of combining multiple resources and trying to come to their own conclusion.

For what it is worth, hopefully instead of trying to support broken infrastructures, global society rolls up it’s sleeves and looks to put in new solutions, instead of band-aids for flawed infrastructure.  In this case I mean things like replacing DNS and core network topology with a new back end, at least designed with some concepts of preventing major issues from being so detrimental.  Granted, Global Society applying similar methods to non-technical processes would be great too.  I hope you enjoyed the rant :bunny:

Firewall Log Fun

This thread is ongoing, but let me start with the results I have from a year worth of dropped firewall connections.

Let’s jump back a minute. I am importing firewall logs for dropped connections into a MS SQL Database. September as you can see is a fun month with 2,096,766 records.
Since my firewall is a Zyxel device, I gave a look at the .csv delimited log output. Easily enough you can use a Data Import Wizard to spin the logs into some tables. Rough table to log structure is as such:

CREATE TABLE zy_2016-09 (
  time VARCHAR(50) NULL,
  source VARCHAR(50) NULL,
  destination VARCHAR(50) NULL,
  priority VARCHAR(50) NULL,
  category VARCHAR(50) NULL,
  note VARCHAR(50) NULL,
  sour_interface VARCHAR(50) NULL,
  dest_interface VARCHAR(50) NULL,
  protocol VARCHAR(50) NULL,
  message VARCHAR(250) NULL,
  col00 VARCHAR(250) NULL,

I am having fun crawling some output. Typically it’s some sort of fancy OpSec to not say your type of network gear, but this is meant to be informative and hopefully helpful.
So let’s crawl some queries and output in the next post.
