Kaspersky Lab just announced they are working on their own Operating System for critical systems.

This is something that is increasingly needed, but is Kaspesrky the best entity suited to produce such OS? To contribute/review it, certainly. But to drive its development? I am not so certain. I would have thought that developing an OS requires more specific skills than just security ones. One could argue that making security the core skill used in developing that OS should make it more secure but I would argue back it could also introduce performance issues… And performance is a health/security risk on its own, especially when speaking about critical systems such as process control environments.

Kaspersky Labs is engaging with different vendors and ICS operators, so they should get some kind of expertise on what their systems req...

There is something about deception, it can bypass a lot of security controls through a very basic principle, to make you believe about something that isn’t there. It is a bit like magic.

Like this WEBSITE, where you can see an example of what the new HTML5 fullscreen function could make you believe. That you are on a bank website, where in fact you are on a phishing site. The previous link is harmless and only serves as an example, one I would advise you to try yourself (you can’t enter any details anyway in case you haven’t understood it isn’t really a Bank of America website).

Basically, they use the HTML5 Fullscreen function to recreate your browser TABS and URL. If you are not used to browse the internet in full screen mode then you would see the trickstraightaway. However, if you are following the trend to browse in full screen mode, especially on mobile phones or on MACs where app...

RSA recently announced their Distributed Credential Protection (DCP) technology which should help address the impact of passwords leakage/theft when the system where they are stored gets compromised. They accomplish that by splitting up stored credentialsacrossdifferent systems.

In its current implementation it uses 2 servers. 1 server (BLUE) stores the password XOR to a random number and another server (RED) stores that random number.
When a user wants to authenticate it uses his password to XOR it with his own Random number. It then sends the transformed password to the BLUE server and the new random number to the RED server.
The BLUE and RED servers then compare the stored password with the one the user just provided. At this stage, I guess it must communicate to the RED server to get the corresponding random numbers.

This process is given an overview ...

According to this FRENCH WEBSITE, a major security vulnerability has been disclosed at the Ekoparty 2012Security Conferencewhich affects some android handsets. It it is possible to reset those affected handsets to factory default settings and in the process wipe out all data.This vulnerability exploits a “secret” code that can be used to trigger the factory reset automatically, without asking any confirmation from the user. That code is:*2767*3855#

There are different methods known to date to push that code onto those handsets:

– SMS in Wap Push mode (where the user would have to click on a link)

– QR Code

– NFC Protocol

Or… if users go to some websites where either

Thinkst is a small security organisation and one of its member recently published a post on their blog regarding the security of an encrypted USB drive. One of his friend lost the password to his USB Freecom Self Encrypted Drive (SED) drive and one of the protection in place was the need to power cycle the hard drive after every 5 bad attempts. This meant a brute force attack was impossible due to the time to plug/unplug the device.

Here comesingenuity, although the author call this a “lame hack”, I actually really like it as he thought outside the box (pun intended). He basically build a new controller to automatically power cycle the drive, and managed to find the lost password after 500 attempts.

I don’t do electronics and am always impressed when hack...

In case you were in any doubts about the security flaws of MD5, in recent days, 2 implementations of MD5 have been shown to have severe security issues.

1) The md5crypt password scrambler used in many Unix based distributions has been deemed as “unsafe” by its author (in fact this has been known for some time now).

2) MD5 collisions were used in the recent Flame malware to bypass Microsoft Update signature certificates.

The sole use of MD5 as a security vector must be avoided.

CloudFlare is an interesting young company, a few years old, as introduced in this Bloomberg article. Although it is tempting to just describe it as being similar to Akamaibecauseit provides web acceleration and DOS protection through the use of a Content Distributed Network (CDN), it is also different. As explained by its founder, Matthew Price, it can understand, analyse and protect all requests to a website, not just a subset. It also has a different price model starting with a free offering and generally being much less expensive than the competition even with its pro/business/enterprise options.

In a nutshell, CloudFlare appears to be a service that can help optim...

In the last few weeks there has been a lot of noise about what looks like the latest State sponsored malware, Flame. You can find a lot of information about it from Kaspersky and also from the CrySyS lab who seems to have done some parallel investigation and call it differently (sKyWIper).

This malware is quite interesting for several reasons:
1) It seems to focus on stealing information rather than being directly disruptive.
2) It has been active for 5+ years and has remained undetected until now.
3) It has an option to delete itself, but in doing so leaves one file. a ~DEB93D.tmp file.
4) It is modular and can/has been used to intercept Microsoft update using fake certificates t...

Note: Many of the security articles I have written about Apple on this blog are negative and the reader could think I do not like Apple. This is actually very far from the truth, I am a big Apple fan; but I am also a security professional and I do not agree with their overall security strategy.

The title of this post is inspired directly from an Article I read on ZDnet, discussing the latest security threat that infected an estimated half a million Mac with malware: “BackDoor.Flashback.39″.

Mac Trojans are evolving and becoming more frequent, last August a Mac Trojan (Bash/Qhost.WB)was found in a fake Flash updater that once installed would redirect google search results to “bad sites”, then in September another Mac Trojan (...
