Reset Your Mobile Memory Card Password 2 minutes

We usually set password for our memory card for privacy and security, but the common mistake every one does at least once in out life time forgetting password. If you set password for mobile memory card, then you should be not forget the password. If you does then the only option is to formate your memory card with the help of the card reader and eventually the loss of all your data stored on it. There is a way to break the security wall. If you are a Symbian device lover then no need to worry about the password. You can crack them in few minutes.



In this tutorial I am going to teach you how to reset your memory card password in easy step. Before we start you need to have X-plore (application used to explore your system files and folder even the hidden folders in your device)



Step1: Install X-Plore in your mobile. If you want to download X-Plore search around internet you can download free trail.

Step2: Open your X-plore apps and Press 0(Zero) and check which you have marked the "show the system files"

Step3: Once you done that now go to the following path C:/Sys/Data/Mmcstore

Step4: Once you reached there you need to press "3" under option to set it in the Hex-viewer

Step5: See the third column you will able to see a line of code ! TMSD02G (c??"?x???6?2?6?2?6). Just check the character between the "?" it is your password ie: 62626

Facebook Hack – View photo albums of non-friends


A new facebook exploit allows anyone to access any photo album of non-friends as long as you have the link.
Facebook Photo Exploit
By following the simple steps shown in above image, you can bypass the security of Facebook and view photos of others online.

All versions of Internet Explorer under threat


Today Microsoft released a new security advisory to help protect users from a vulnerability affecting Internet Explorer versions 6, 7, and 8. Exploiting this vulnerability could lead to unauthorized remote code execution inside the iexplore.exe process.
Internet Explorer loads mscorie.dll, a library that was not compiled with /DYNAMICBASE (thus not supporting ASLR and being located always at the same base) when processing some HTML tags. Attackers use these predictable mappings to evade ASLR and bypass DEP by using ROP (return oriented programming) gadgets from these DLLs in order to allocate executable memory, copying their shellcode and jumping into it.
Although Microsoft is currently not aware of any attacks, given the public disclosure of this vulnerability, the likelihood of criminals using this information to actively attack may increase.
Users of Windows Vista and later versions of Windows are strongly encouraged to protect themselves against this issue by installing the freeEnhanced Mitigation Experience Toolkit (EMET) and proceed to protect the iexplore.exe process.
When EMET is in place, this type of exploit will most likely fail. This is because of at least three mitigations:
  • Mandatory ASLR: This mitigation will force the mscorie.dll to be located on random addresses each time.
  • Heap Spray pre-allocation: Some of these exploits use some common used heap pages for placing ROP data such as 0x0c0c0c0c.
  • EAT Filtering: Running shellcode can potentially be blocked by this mitigation.
Additionally, users should be aware that protected Mode in Internet Explorer on Windows Vista and Windows 7 helps to significantly limit the impact of currently known exploits. Protected Mode is on by default in Internet and Restricted sites zones in Internet Explorer 7 and 8, and prompts users before allowing software to install, run or modify sensitive system components.
Microsoft continues to investigate the vulnerability and will release a comprehensive security update once available.

Mozilla site exposed encrypted passwords


On December 17th, Mozilla was notified by a security researcher that a partial database of addons.mozilla.org user accounts was mistakenly left on a Mozilla public server. The security researcher reported the issue to us via our web bounty program. We were able to account for every download of the database. This issue posed minimal risk to users, however as a precaution we felt we should disclose this issue to people affected and err on the side of disclosure.
The database included 44,000 inactive accounts using older, md5-based password hashes. We erased all the md5-passwords, rendering the accounts disabled. All current addons.mozilla.org accounts use a more secure SHA-512 password hash with per-user salts. SHA-512 and per user salts has been the standard storage method of password hashes for all active users since April 9th, 2009.
It is important to note that current addons.mozilla.org users and accounts are not at risk. Additionally, this incident did not impact any of Mozilla’s infrastructure. This information was also sent to impacted users by email on December 27th.

MHTML vulnerability under active exploitation


The flaw, which was first highlighted by Microsoft in an advisory in January, allows an attacker to inject a client-side script into the response to a request made by Internet Explorer.
The script could allow a hacker to compromise the user by performing actions online that appear to have originated from the user; by stealing information from the user; or by otherwise trying to fool them.
MHTML, or Mime HTML, is a standard that allows web objects such as images to be combined with HTML into a single file. The vulnerability lies in how MHTML interprets Multipurpose Internet Mail Extensions (Mime) for content blocks in a document.
All these attacks abuse a publicly-disclosed MHTML vulnerability for which an exploit was publicly posted in January 2011.
Users browsing with the Internet Explorer browser are affected.
For now, users and corporations seriously consider deploying Microsoft’s temporary Fixit to block this attack until an official patch is available.
