Unix and macOS malware

My colleagues Fabio Assolini and Vicente Diaz wrote two blog posts recently regarding the Rogue AVs for MAC OSX. After executing it on a test machine, and playing with it, I noticed there was some hidden information in the About Window

When my colleague Fabio wrote about a Rogueware campaign targeting MAC users, I investigated a bit into the origin of these campaigns. It was interesting how different researchers were getting those samples through searching images on Google. However, different searches always arrive at the same result, leading to the question: How many search terms have been poisoned?

In this Q&A session with Ryan Naraine, Kaspersky Lab malware researcher David Jacoby dispels the myth surrounding Linux as a malware-free platform and makes the case that misconfigurations and other security problems on Linux contributes to the malware epidemic on Microsoft’s Windows operating system.

Apple has released MacOS X 10.6.7 with several bugfixes and security-patches. This patch bundle also includes a silent update to Apple‘s built-in Xprotect anti-virus functionality.

With Apple fans waiting for the release of the Greenpois0n jailbreaking tool, the cybercriminals are exploiting the fuss with “Greenpois0n” trojans.

Providing randomly generated input to different open source disassembler libraries generates surprisingly differing output and the CPU interprets it differently yet again.

On 28th August, the latest update for MaxOS X was released – Snow Leopard. It differs in one very telling way from previous versions – for the first time in Apple’s long history, the company’s implemented an antivirus scanner.

Windows may be ubiquitous, but there’s a thriving variety of alternative operating systems for enterprise and home use. However, the alternatives aren’t as risk free as some people might think

It’s often argued that *nix systems are secure, and there aren’t any viruses or malware for such systems. This hasn’t been true for a long time, as two recently detected malicious programs prove.

Well, we congratulated Mac on its 25th birthday – and then found some new rogueware. We’ve got two pieces of malware and detect them both as not-a-virus:FraudTool.OSX.iMunizator.

Traditionally, malware writers have overlooked Mac in favor of targeting Windows with its bigger market share. But the proof-of-concept samples which appear periodically show that Macs aren’t invincible.

This article is the third in a series devoted to the evolution of viruses and anti-virus solutions

The Race to Zero is not a questionable affair – no questions about it…it is unethical.

It is more than 20 years since the first PC virus appeared. Since then, the nature of threats has changed significantly

Talk about non-Windows malware and most people automatically think of Linux, MaxOS X etc. But this very modern attitude overlooks a couple of interesting stages in the history of computer virology.
