User-mode kernel code??

Eric Hansen Eric Hansen Profile: Eric Hansen

Its finally possible!  At least in Python.

KPlugs (http://www.kplugs.org/) is a Python module that allows people to access data inside of the kernel itself, usually unheard of unless you write a crafted module or other driver.

The security aspects of this is interesting, and I haven’t really looked at it enough to tell if its actually safe to use in practical purposes, but its still an interesting tool to use.  Especially with the rise of scripting languages and yet not being able to run them beyond user level, this could potentially lead to a better advantage in making that happen.

Encrypted Persistence

This isn’t old technology, in that persistence has been around for a good few years, but now Kali Linux is offering it in encrypted form.

Persistence in this from is basically a way for live USB-ran distros to keep data that was created/modified while running from the USB.  While I never use this feature, it is nice to have if you’re an on-the-go kind of person.  The added feature of encryption has been long over due and one of the reasons I have never used persistence to begin with.

XSS Game

Google has released an XSS game to showcase what and how XSS (cross site scripting) works. You can view it here: https://xss-game.appspot.com/ and its pretty fun, actually. Reminds me a lot of WebGoat but a lot less intense.

R.I.P. TrueCrypt

This marks the end of an era with TrueCrypt ceasing operations.  Granted, it was nothing more than a distant memory for the longest time as better solutions came around, at least on Linux, such as dm-crypt. Its still sad to see this day come since I’ve used TrueCrypt a lot from the moment I got into IT a good 10 years ago.

Lavabit bit the dust…again

For those who aren’t familiar with Lavabit, it was a service that offered encrypted email service that got cease-and-desist sort of letters form the government once the Edward Snowden event happened.  This was mostly a “we want those emails, give them to us!” email, which Lavabit eventually said “you want all?  you have none!”

Not really sure what they expected, though, when the US system is what caused the issue to begin with.

Google Hacks reCAPTCHA

This is the problem with “improving” features.  You make a change in one spot of the code and you break a million other things.  Though I think it is admirable that Google admitted to this issue.  Now to just hope they fix it so they don’t end up like AOL…

Strong Push to Pure-SSL?

Eric Hansen Eric Hansen Profile: Eric Hansen

http://www.wired.com/2014/04/https/

Should the entire Internet be encrypted?  No.  I don’t see the point of encrypting a website about my neighbor’s dog, for example.  Do I think it should be enforced/mandated for sites that hold sensitive information?  Most definitely.

I think this heartbleed thing has blown things out of control a little too much.  We need to fix the issues we have now before we mandate a whole new list of rules.

Reddit censors things?!

Eric Hansen Eric Hansen Profile: Eric Hansen

http://www.bbc.com/news/technology-27100773

The company that owns Reddit doesn’t, but the mods who run (ran?) the technology community removed posts silently that included certain words.

This is done most likely by a “bot” someone made to check for new posts and delete all posts that had any words in a blacklist.

Ultimately this won’t stop me from visiting the site but since people think censorship is a major thing still, why not offer an opinion?

BitCoins for Donations

Eric Hansen Eric Hansen Profile: Eric Hansen

So again people are trying to push the BitCoin rave to be for governmental donations.  With the recent movements towards people accepting it as a valid form of currency, I wouldn’t be surprised if it gets approved.  But, even if it does, who will use it?

Currently no physical stores (that I’m aware of) accept it, and even to get a BitCoin it tends to be rather expensive time-wise.  Would it be worth it to spend that on a political donation?

DarkNet, meet DarkMarket

Eric Hansen Eric Hansen Profile: Eric Hansen

http://www.wired.com/2014/04/darkmarket/

Truthfully I’m shocked it took this long, especially with BitCoin being around for a long while now.  But, then again, BitCoin (BTC) is finally being considered a legitimate form of currency, so hey.

While I have no intention of using DarkMarket, it makes me think of DarkNet, which is essentially another Internet that is only accessible via Tor.  This might be worth keeping an eye out, though.  Even if this doesn’t take off, the code is open sourced which can make it pretty viable in the future.
