Unix and macOS malware

Recently, news appeared about an interesting attack where cybercriminals infect iPhones and Mac OSX users with a rather peculiar malware dubbed WireLurker. Yesterday, our friend Jaime Blasco from Alienvault discovered a Win32 malicious tool that appears to be related.

We got an interesting file for analysis a short while ago. It turned out to be a sample of modular malware for MacOS X.

A couple weeks ago, my colleague Mikhail K posted on the analysis of several bots, including a bot implementing some extraordinary DNS amplification DDoS functionality. Let’s explore some additional offensive details of this crew’s activity, and details of the overall situation, in the past week.

It described a Trojan with sufficiently versatile DDoS functionality. The capability that we found the most interesting was the Trojan’s ability to conduct DNS Amplification-type attacks.

A Trojan encrypter for Mac OS X is something we haven’t yet seen, but is, it seems, totally realistic.

Absolutely all of the latest versions of Microsoft Word and some versions of Internet Explorer maintain critical vulnerabilities enabling remote code execution.

In response to numerous requests for comments and clarifications after our presentation at the Kaspersky Security Analyst Summit 2014, we have created this FAQ.

During the past months we have been busy analysing yet another sophisticated cyberespionage operation which has been going on at least since 2007, infecting victims in 27 countries. We deemed this operation “The Mask”.

Early this year, we received a malicious Java application for analysis, which turned out to be a multi-platform bot capable of running on Windows, Mac OS and Linux. The bot was written entirely in Java. The attackers used vulnerability CVE-2013-2465 to infect users with the malware. Initializing and decrypting strings To make analyzing and detecting

In our search for various types of malicious code for Mac we recently came across a rather interesting peculiarity in Safari. It turns out that Safari for Mac OS, like many other contemporary browsers, can restore the previous browsing session. In other words, all the sites that were open in the previous session – even

Over the last few months we have seen a series of very similar targeted attacks being blocked in our Linux Mail Security Product.

In partnership with researchers at AlienVault Labs, we ve analysed a series of targeted attacks against Uyghur Mac OS X users which took place during the past months.

Yesterday, Jens ‘atom’ Steube, which most people know as the author of ‘hashcat’ – a GPU accelerated password recovery tool, released his Gauss cracker as open source software under a GPL license
