Phishing still fools people, but at least more are cautious

While people still have a really hard time telling the difference between legit and phishing emails, at least there is enough awareness of the phishing threat that many people will err on the side of caution when it comes to clicking on links.This was one finding from Carnegie Mellon University's CyLab in a study titled "Quantifying Phishing Susceptibility for Detection and Behavior Decisions" that published recently in the journal Human Factors.MORE: New tech can help catch spearphishing attacksTo read this article in full or to leave a comment, please click here

IDG Contributor Network: Daisy-chaining APIs makes serverless sense

Enterprise and startups are moving to cloud-based infrastructure to create an API-enabled value chain for new products and workflows. With this has emerged the idea of serverless infrastructure: running functions and applications completely in cloud-based servers where the hosting provider handles all of the sysadmin requirements.This is a new frontier in how business is leveraging cloud, and it is set to explode, especially amongst system integrators and consultants, as more data from sensors and machines are incorporated and as traditional businesses move even more of their IT infrastructure to the cloud.But to take advantage of this opportunity, businesses need to have their services and data accessible via application programming interfaces (API), which for most businesses is still just an emerging trend.To read this article in full or to leave a comment, please click here

AT&T jumps into SD-WAN market; partners with IBM

AT&T today jumped headfirst into the fast-growing software-defined Wide Area Network (SD-WAN) market with a new offering it hopes to bring to market next year based on technology from SD-WAN startup VeloCloud.SD-WAN is gaining steam thanks to its ability to bring software-defined networking (SDN) controls to the wide area network. SD-WANs allow customers to integrate multiple network connection types and let software intelligently route traffic based on application profiles and available network types. Gartner has estimated that SD-WAN can save customers significant costs compared to traditional WAN architectures too. IDC predicts SD-WAN will be a $6 billion market by 2020.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Many people abandon security, risky behavior surges

People are sick and tired of being told to be more secure in their use of computers and when participating in online activities. So much so that they’re simply ignoring the blitz of annoying demands and are carrying on as imprudently as they’ve always done, according to National Institute of Standards and Technology (NIST) researchers.The U.S. Department of Commerce-operated lab recently published a report (subscription) on the subject in IEEE’s IT Professional Journal.The study’s participants “expressed a sense of resignation and loss of control” when the scientists asked them about their online activity, such as shopping and banking.To read this article in full or to leave a comment, please click here

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.

picture3_pxe_boot_password_hash

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
