New Mac malware opens secure reverse shell


A new backdoor Trojan for OS X is making the rounds, attempting to set up a secure connection for a remote hacker to connect through and grab private information.

The malware, dubbed “Pintsized” by Intego, is suspected of using a modified implementation of OpenSSH to set up a reverse shell that creates a secure connection to a remote server.

How can you detect if your computer has been violated and infected with DNS Changer?


For example, the http://www.dns-ok.us/ will state if you are or are not infected (see below).

  • No Software is Downloaded! The tools do not need to to load any software on your computer to perform the check.
  • No changes are performed on your computer! Nothing is changed on your computer when you use sites like http://www.dns-ok.us/.
  • No scanning! The “are you infected with DNS Changer” tool does not need to scan your computer.

If you think your computer is infected with DNS Changer or any other malware, please refer to the security guides from your operating system or the self -help references from our fix page (http://www.dcwg.org/fix).

DNS Changer Check-Up

DNS Resolution = GREEN
Your computer appears to be looking up IP addresses correctly!

Had your computer been infected with DNS changer malware you would have seen a red background. Please note, however, that if your ISP is redirecting DNS traffic for its customers you would have reached this site even though you are infected. For additional information regarding the DNS changer malware, please visit the FBI’s website at:

Windows malware: are you safer today than you were 10 years ago?


They don’t make malware like they used to.

That’s not a setup for a joke—it’s a fact. As I was researching some recent columns on malware outbreaks for PCs and Macs, I found myself reading old articles about computer security from the beginning of the 21st Century. Some of those articles and the threats they describe seem downright quaint in retrospect, while others were positively prescient.

Virus and malware protection for the Mac


Now that we’ve discussed the benefits of having antivirus and malware protection, I’m going to suggest a few Apps from the Mac App Store for protecting your Mac.

Bitdefender: Virus Scanner is free, one of the few that boasts the ability to detect Flashback, and is capable of scanning for potential Windows threats that could be tucked away in an email.

ClamXav is also free and uses the open source antivirus engine ClamAV known for it’s fast definition releases.

Kaspersky Virus Scanner $9.99, is a well known application for the PC. What you get with this app is reliable definition updates and streamlined performance; when speed is important, performance might be the determining factor.

Virus and malware protection for the Mac


Previously, I discussed ways that you can reduce the risk of contracting malware on Macs. I prefer to discuss security measures that don’t require additional software, but at times, you need tools that can better tackle the problem when managing large environments is your responsibility. It can also be much easier to deploy software and let the software manage the responsibility of monitoring the environment rather than micro-managing each machine individually. The selection of malware and antivirus applications for the Mac are sparse, but they’re solid, having learned from their PC counterparts.
