PGP Web of Trust: Core Concepts Behind Trusted Communication

Filed under
Security

If you've ever used Linux, you've most likely used OpenPGP without even realizing it. The open-source implementation of OpenPGP is called GnuPG (stands for "GNU Privacy Guard"), and nearly all distributions rely on GnuPG for package integrity verification. Next time you run "yum install" or "yum update", each package will be verified against its cryptographic signature before it is allowed to be installed on your system. This assures that the software has not been altered between the time it was cryptographically signed by distribution developers on the master server, and the time it was downloaded to your system.

However, far fewer people have actually used GnuPG for what it was originally designed for -- secure exchange of information in an untrusted medium (such as the internet), and even fewer have a good understanding of how the trust relationships are supposed to work.

In this mini series of articles, we'll take a look at what the web of trust is and how to use it to set up a secure and trusted communication.

Java-based malware driving DDoS botnet infects Windows, Mac, Linux devices

Security

The cross-platform HEUR:Backdoor.Java.Agent.a, as reported in a blog post published Tuesday by Kaspersky Lab, takes hold of computers by exploiting CVE-2013-2465, a critical Java vulnerability that Oracle patched in June. The security bug is present on Java 7 u21 and earlier. Once the bot has infected a computer, it copies itself to the autostart directory of its respective platform to ensure it runs whenever the machine is turned on. Compromised computers then report to an Internet relay chat channel that acts as a command and control server.

A basic tenant of open-source software security has long been the idea that since the code is open, anyone can look inside to see if there is something that shouldn't be there.

IBM Shows That Collaborations With the NSA Are a Company’s Death Knell

Filed under
Security

At this stage, despite deceiving marketing, IBM needs GNU/Linux and Free software more than GNU/Linux and FOSS need IBM. Recently, the President of the Open Source Initiative (OSI) called IBM a patent troll. IBM can carry on openwashing its business with OpenStack [11,12], Hadoop [13] and so on (even OpenOffice.org), but until it stops serving the NSA, the software patents agenda and various other conflicting interests (causes that harm software freedom and GNU/Linux) we are better off nurturing “true” (as in completely) Free software companies.

If Microsoft thinks old Tor clients are risky, why not Windows XP?

Earlier this week, Microsoft revealed that it had been going into users computers and removing outdated Tor clients. At first glance, this might seem like a crazed, misplaced attack on the Tor network, not unlike a campaign by a certain Irish politician, but the issue runs deeper than first thought.

Renowned cryptographer believes his 'Blackphone' can stop the NSA

Security

Revelations about how insecure our communications are have been a daily fixture of the news cycle recently, and it's in this climate that a pair of companies are combining to launch a new smartphone focused on privacy. The Blackphone will run a "security-oriented" version of Android named PrivatOS, which the companies say will allow users to securely place and receive phone calls, text messages, video chat, transfer and store files, and "anonymize your activity" through a VPN.
