DEFCON 17: More Tricks For Defeating SSL – YouTube

Posted by jpluimers on 2016/07/11

Still relevant after a few years: DEFCON 17: More Tricks For Defeating SSL – YouTube.

I landed there after trying to find out how to verify the Internic root server file is actually pubished by Internic via authentication – Ways to sign gpg public key so it is trusted? – Information Security Stack Exchange.

I remember reading his “if you have to perform any cryptographic operation before verifying the MAC on a message you’ve received, it will somehow inevitably lead to doom” post (Moxie Marlinspike >> Blog >> The Cryptographic Doom Principle), but never noticed his videos.

It is still relevant as there are lots of implementations still vulnerable to these kinds of attacks.

Many more of his blog entries are interesting as well:

Sysinternals Suite – lots of tools are now available as 64-bit as well

Posted by jpluimers on 2016/07/08

In the past the Sysinternals Suite used to have only a few 64-bit versions of their tools, but recently they added many more.

The documentation doesn’t reflect this yet, but the online versions do:

These are 64-bit:

Work around G+ “403. That’s an error.” errors

Posted by jpluimers on 2016/07/08

I’m not yet sure what the exact cause is, but at irregular intervals when clicking on Google Plus links, they show as “403. That’s an error.”.

They appear both when I have multiple WAN connections or a single WAN connection, which leads me to suspect that G+ doesn’t cope well when

  • you have a lot (dozens) of Google related pages open (Drive, Mail, Search, Documents, etc) as Google Plus is embedded in each of them
  • you rapidly browse through your G+ backlog (the G+ counter is > 50 since you follow a lot of people/communities and you quickly do catch-up on them)

In a future post, I will explain how I created the workaround, but here it is:

Work around G+ “403. That’s an error.” errors

Basically it translates links

The latter was the original link I clicked in the first place. The former what G+ comes up with.

After a while, G+ comes back to its senses and allows the latter links again, so the page allows you to parse the former then put them in a list like this:

One decoded URL per list-item.

HOWTO: Multirouting with Linux : Luke Cyca Dot Calm

Posted by jpluimers on 2016/07/08

Multihoming without BGP with home routers and Linux. Need to apply this on OpenSuSE one day: HOWTO: Multirouting with Linux : Luke Cyca Dot Calm.

Basically it does Multirouting of Sessions using NAT, routing tables, rules, removal of the default routing and adding a round robin routing, fixing DNS, adding more rules and creating a failover script.

In case it ever goes offline: the WayBack Machine link.

Some more background research links:

James Newman built himself a 16-bit Megaprocessor using transistors in frames taking 12 by 2 meters. Wow!

Posted by jpluimers on 2016/07/07

It took James Newman more than one and a half years of actually building progress and more than that (thinking about it started in 2011) for designing his own Megaprocessor using transistors.

For like EUR 50000 and a lot of “learning opportunities” he built himself a room full of visual computing: you can see the LEDs on all the PCB boards indicating exactly what’s going on (heck: he even made the RAM visualise an actual tetris implementation).

All for the sake of understanding transistors and discrete logic after which things got out of hand.

Hopefully a tech museum will buy this.

His site as a truckload of information, for instance the Source: Megaprocessor – FAQ: good/bad/ugly linking to lots of technical details and decisions made (like throwing out surface mount components but using lead based solder or having dual output logic).

There’s a lot of video too (like Megaprocessor – How ?) but – especially these weeks – the downloading is slow, to it’s faster and easier to watch his Youtube playlists:

They are currently 6 videos each, but he has uploaded more videos and is working on more.

Finally, James even built an assembler for this 16-bit processor. How cool is that!

Resource decompiler – converting/decompiling/extracting .RES files into .RC files and separate resources

Posted by jpluimers on 2016/07/07

via: Resource decompiler

One day I’m going to need ResourceHacker as it has an -extract option to extract resources.

The above link even has a batch file that can server as a start automating that process:

@echo off
set file="GeneSys"

if exist %file%.rc del %file%.rc

ResHacker.exe -extract %file%.res, %file%.rc,  Bitmap,,
ResHacker.exe -extract %file%.res, temp.rc,  Icon,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  Dialog,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  Menu,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  StringTable,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  Accelerators,,
type temp.rc >>%file%.rc
ResHacker.exe -extract %file%.res, temp.rc,  VersionInfo,,
type temp.rc >>%file%.rc
del temp.rc

I save it as extract.bat and a commandline usage: extract GeneSys will extract all the resources from GeneSys.res

–jeroen

PS: as the MASM forum sometimes nags with logins, I saved the above page in the wayback machine.

I’ve verified that [WayBack] ResourceHacker and the downloads ([WayBack] installer and [WayBack] portable) are there too.

Vysor Pro Feature – Go Wireless to mirror and control your device without a USB Cable…

Posted by jpluimers on 2016/07/06

If you have a [Wayback/Archive] Vysor Pro (either subscription or one-time payment for life-long usage), then you can use this new [Wayback/Archive] New Vysor Feature – Go Wireless Click that button to mirror and control your without a USB cable…

There are more Pro features to come; currently they are:

  • High Quality Mirroring
  • Fullscreen Mode
  • Go Wireless
  • Vysor Share
  • Drag and Drop Files
  • Access to all future features

If Google Pay doesn’t work in your country, then you can use PayPal. When that doesn’t work either, well…

Another nice Vysor Pro feature: [Wayback/Archive] Vysor Share Server – an easy Android device farm: You can share all your Android devices at once using the new Share All feature. – Koushik Dutta (Koush) – Google+

case insensitive files systems and git – Lesson Learned – I Can’t Get My Git Repo Clean! | DrupalEasy

Posted by jpluimers on 2016/07/06

via: Lesson Learned – I Can’t Get My Git Repo Clean! | DrupalEasy

One file kept getting added to the git modified list: service/src/main/MySOAPdefinition.pas.

It was part of a repository that had been migrated from SVN (more on that in a future blog post) and along the way been renamed in directory service/src/main from MySOAPdefinition.pas to MySoapDefinition.pas. SVN (and TortoiseSVN) don’t object to this. But git does.

You’d see this on the command-line:

>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   service/src/main/MySOAPdefinition.pas

no changes added to commit (use "git add" and/or "git commit -a")

>git add service\src\main\MySoapDefinition.pas

>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   service/src/main/MySOAPdefinition.pas

no changes added to commit (use "git add" and/or "git commit -a")

Basically the add would do nothing.

On Windows, this is how to get around this:
