XP still Continues though "eXPired"

1.    XP has now got the authorized prefix and suffix to get renamed as "eXPired" since it has been now officially announced by Microsoft as discontinued and has advised XP and Office 2003 users to migrate to Windows 7 and Office 2010 and thus systems are left vulnerable to new forms of malware. No further support to XP...no patches to update...no updates by Microsoft.....but certainly it will take time for XP to get disowned by more then a decade old loyal user population most of whom made their first PC experience with a XP machine...for a home guy who surfs net...it will be difficult to make him/her understand about how vulnerable he/she is now....actually very difficult.

2.    But what about the corporates and govt sector offices? I am sure private sector will make a fast change since it may adversely effect their business model in case of a undesired info leakage or a hack!!!Only recently I made a visit to a post office in Delhi for doing a speed post...wherein the dedicated  loyal postmaster was using a xp machine connected to Internet.I informally asked him about any upgrades in OS planned in their department to which he replied confidently that it's not required since it is working fine.Today the Indian postal department is slowly getting online.Today thanks to vision implementation of the government(though late) that we are able to locate the movement of a speed post letter...what time it was opened..whats the location and when it got delivered...etc etc..but all this can go waste and get a setback if the backbone nodes are not updated and monitored....more so if the staff handling all the machines are low on security aspect.

3.   Well...this postal department is one of the examples cited here since I just interacted with one of them today...but the risk stakes are high when we see this at national level...all the online-governance machines located in remote areas...have they been ensured removed of XP?....if it has not been done....this can be just on the lines of zero day exploits...in this case there must be millions of machines thrown open to hacking....and invasion to classified information.

Browser Updates

1.   Without emphasizing on the need of why we should always keep our browsers updated,I am briefly bringing out here how to check and update your browsers.These browsers are invariably the most commonly used one's ...so I just updated few of them although the browsers exists in plenty!!!!


Firstly

To check the version of your Web Browser, Open the  Browser 
and do the following actions :


For Opera Browser

Click on “Main Menu > Help > About Opera”.


For Firefox

Click “Main Menu >Help> About Firefox.

For Internet Explorer

Press Alt+H and Click on “About Internet Explorer”.

For Apple Safari

Press Alt+H and Click on “About Safari”.

Secondly

To check whats the latest version doing the surfing....i advise two options...either you can simply ask google or check form the respective websites of the web browser...or another easy(but third party) way out is to check the latest versions available for download at http://www.filehippo.com/software/internet/browsers/

HIT WICKET & OUT- Microsoft Genuine Patch crashes WINDOWS 7


1.     This is some news from the corridors of Microsoft.A genuine MS patch released for Windows 7.The patch in the dispute is "Microsoft Security Bulletin MS13-036"

2.  Redmond from Microsoft's Security Response blog blamed the glitch on conflicts with third-party software:

We are aware that some of our customers may be experiencing difficulties after applying security update 2823324, which we provided in security bulletin MS13-036 on Tuesday, April 9. We’ve determined that the update, when paired with certain third-party software, can cause system errors. As a precaution, we stopped pushing 2823324 as an update when we began investigating the error reports, and have since removed it from the download centre.

Contrary to some reports, the system errors do not result in any data loss nor affect all Windows customers. However, all customers should follow the guidance that we have provided in KB2839011 to uninstall security update 2823324 if it is already installed.

3.   That means Windows 7 users should uninstall the security patch Microsoft issued on Tuesday because some PCs failed to restart after applying the update.....:-).Microsoft has advised users of Win 7 and Windows Server 2008 R2* to roll-back the patch.




4.   More about the patch here.Thanks http://www.theregister.co.uk/security/

Biggest release of Patch update by MICROSOFT

1.    Patches by MS to be released today are said to be the biggest and largest batch of updates by Microsoft since Oct 2003.According to Microsoft, this batch will be the LARGEST in its history with no less than 16 security updates designed to address a total of 49 vulnerabilities in Windows, Internet Explorer, MS-Office and the software giant's .NET Framework.

2.    All this effort and size of the patches by MS reflects how vulnerable each one of us remains to the hacking and leak of personal info in wrong hands....the batch of updates will include Windows 7 critical updates,updates for Internet Explorer, MS -Office 2010.And all those happy using the pirated copies of OS across remain as vulnerable as they are already....

RISK MANAGEMENT : Beware while u update with Patches

1. A zero-day exploit as discussed at an earlier post in this blog .....Some thing more to it...

2. A good extract straight lift from Infosecurity-magazine.com

"For a vendor, developing the update is not the part that takes time – testing is. We have more than 600 million downloads when we publish an update. If we “just” break 10% of the systems the update is installed, it would be a huge denial of service. So testing is the name of the game. How well is an unofficial patch tested?Often the vendor publishes workarounds (at least we do). This should be part of your risk mitigation strategy. Would the workaround be acceptable to buy you time?

How far do you trust the author of the unofficial update? How big is the risk that the update comes with pre-installed malware? The question immediately comes up: Why should we trust a vendor? Well, you bought or downloaded the software at the first hand – so, you decided to trust the vendor at the beginning.

What do you do once the vendor releases an update? Can you de-install the unofficial update?

Basically, it is a risk management decision, which should include at least the questions I raised above. Do not just run for the unofficial update – to me it should be really the last resort, if even!"
