10 ways of resetting a lost linux root password

April 22nd, 2009 by Dev Team in Linux, Privilege Escalation

via: handlewithlinux.com

A good password has the problem of being difficult to remember. And sometimes you might need to get in to a system where the root password is long forgotten (or left with the system administrator before you).
Luckily there are ways of getting access to systems without having the password. This is of course in a sense also a security risk. That’s why you should always be aware that having unattended physical access to a computer system means the same as having root access to the operating system. Unless the information on a system is encrypted, it’s only as save as the room it’s in.

The method to use to reset the password if you lost the root (or only) password depends on the configuration of your system. But it mostly comes down to two separate tasks:

– get write access to the root partition

– change the password/circumvent control

Here are some things you can try from easy to more complicated. (more…)

Saved Password Locations

Many people ask about the location in the Registry or file system that applications store the passwords. Here is a list of password storage locations for popular applications compiled by Nir Sofer.
Be aware that even if you know the location of the saved password, it doesn’t mean that you can move it from one computer to another. many applications store the passwords in a way that prevent you from moving them to another computer or user profile. (more…)

WPA Wi-Fi encryption is cracked

November 6th, 2008 by admin in News, Wireless

Security researchers say they’ve developed a way to partially crack the Wi-Fi Protected Access (WPA) encryption standard used to protect data on many wireless networks.

The attack, described as the first practical attack on WPA, will be discussed at the PacSec conference in Tokyo next week. There, researcher Erik Tews will show how he was able to crack WPA encryption, in order to read data being sent from a router to a laptop computer. The attack could also be used to send bogus information to a client connected to the router.

WIFI Cracking Using GPUs

October 10th, 2008 by admin in News, Password Info, Wireless

We all know cracking techniques through graphics cards speciifically CUDA based NVidia is on the rise. Now the programmers have set their sights on WIFI cracking. One group reportedly bored through WPA and WPA2 encryptions using a brute-force technique juiced with one of Nvidia’s latest graphics cards . The card supposedly made the “password recovery” process up to 10,000 percent faster than CPU-based cracking. (more…)

Trillian Passwords

March 27th, 2008 by Dev Team in News, Trillian

The trillian passwords are stored separately in .ini files (i.e. msn.ini,yahoo.ini aim.ini etc). These are stored in your trillian directory (usually c:\program files\trillian\) in the “users” folder.

Within the users folder, the ini files will either be in a folder called “default” or a folder named after your username.

c:\program files\trillian\users\default\msn.ini (more…)
