Happy 25th once again to Linux, ‘the little OS that definitely could’

Aug. 25 may be Linux's official birthday, but Oct. 5 is in many ways the day it began to make a real mark on the world. That's when Linux creator Linus Torvalds officially released the first Linux kernel into the wild."As I mentioned a month(?) ago, I'm working on a free version of a minix-lookalike for AT-386 computers," Torvalds wrote in a newsgroup post on Oct. 5, 1991. "It has finally reached the stage where it's even usable (though may not be depending on what you want), and I am willing to put out the sources for wider distribution."To read this article in full or to leave a comment, please click here

Hacking DRBL Client PXE Boot Password

In a previous tutorial I showed installation of Clonezilla Server Edition on Ubuntu using my own Bash script. We configured PXE (Pre eXecution Environment)) password for clients so when the clients booted a password had to be entered to startup. This tutorial explains two different ways how to get and crack the PXE boot password.

picture1_pxe_drbl-_client_password_required

Picture 1 - Client Requires to Enter PXE Password During Startup

First, we should mention some facts. The PXE client password is stored in plain text in a configuration file /etc/drbl/drblpush.conf. The password is secretpassword and it can be found in a dictionary rockyout.txt.

Picture 2 - Plain Text PXE Client Boot Password

The same PXE client password is stored as a hash in a file /tftpboot/nbi_img/prelinux.cfg/default.

Picture 3 - PXE Client Boot SHA-1 Base64 Encoded Salted Hash

The hash is created by utility /usr/sbin/sha1pass on DRBL server. It is a Perl script which takes two arguments from STDIN - a password and salt and it creates SHA-1 base64 salted hash.

Picture 4 - Perl Script fo Generating Hash from Password and Salt

Explanation:

$4$ - SHA-1 base64 encoded salted hash
2mNryVVj - salt
WIWlkNc6cA9+eQqcf9xU0d5IvVQ - hash

They are several methods how to obtain PXE boot Continue reading

The ever expanding menu…

A short note reminding the gentle readers who wander in to this site of the riches of information available in the main menu to the left of this post…

rule 11 reader takes you to a subscription form for the mailing list. The format and frequency of the mailing list is a little messed up right now, and I always mean to do more with it, but never seem to get around to it.

Worth Reading: a troubling new chapter for the ‘net

For the better part of a day, KrebsOnSecurity, arguably the world’s most intrepid source of security news, has been silenced, presumably by a handful of individuals who didn’t like a recent series of exposés reporter Brian Krebs wrote. The incident, and the record-breaking data assault that brought it on, open a troubling new chapter in the short history of the Internet. The crippling distributed denial-of-service attacks started shortly after Krebs published stories stemming from the hack of a DDoS-for-hire service known as vDOS. The first article analyzed leaked data that identified some of the previously anonymous people closely tied to vDOS. It documented how they took in more than $600,000 in two years by knocking other sites offline. A few days later, Krebs ran a follow-up piece detailing the arrests of two men who allegedly ran the service. —Ars Technica

Avaya takes network management to the cloud

Historically, most non-networking professionals have considered the network to be the “pipes” or “plumbing” of the organization—something you needed, but low value.Over time, though, the network has steadily increased in value. In today’s digital era, where everything is connected and more applications and services are moving to the cloud, the network has increased significantly in value. It connects employees, customers and guests, and it is the last line of defense for securing the business.Because of the increased business value, how networks are managed must change. The legacy process of touching every device in every location is laborious and filled with errors. The 2016 ZK Research Network Purchase Intention Study showed that the highest cause (35 percent) of network downtime is due to human error from manual configuration. Traditional management is also very slow. Turning up a new location or even making simple changes often required a network engineer to be on site.To read this article in full or to leave a comment, please click here

Yahoo calls report of secret email scanning ‘misleading’

Yahoo has called a Reuters article about a secret email scanning program "misleading," and said no such system exists. On Tuesday, the Reuters article claimed that Yahoo had created the custom software program after receiving a classified U.S. government order. That software program is reportedly capable of scanning all incoming emails from Yahoo customers for information provided by U.S. intelligence officials.However, on Wednesday Yahoo disputed the report.“We narrowly interpret every government request for user data to minimize disclosure. The mail scanning described in the article does not exist on our systems," the company said in an email. To read this article in full or to leave a comment, please click here
