Targeted Attacks Using Malicious PDF Files
( 221 days 15 hours ago)
LinuxSecurity.com: Dating back to the end of February, we have been tracking test runs of malicious PDF messages to very specific targets. These PDF files exploit the recent vulnerability CVE-2008-0655.
Ever since the end of March, beginning of April, the amount of samples seen in the wild has significantly increased. Interestingly enough, there is almost no "public, widespread" exploitation. All reports are limited to very specific, targeted attacks. However, due to the wide scope of these attacks, and the number of targets we know of, we feel a diary entry was in order.

Protecting Directory Trees with gpgdir
( 221 days 15 hours ago)
LinuxSecurity.com: gpgdir uses GNU Privacy Guard (GnuPG) to encrypt and decrypt files or a directory tree. You could accomplish the same objective by tarring the filesystem up and then encrypting the tar.gz file with GnuPG, but then you would still have to shred or wipe every file in the original directory tree. With gpgdir the whole tree is encrypted in one command. Do you use gpgdir? What do you think about it? This article goes through everything you need to encrypt and data on your system.
