Mac Shield is just the latest variant of a piece of malware that has been hitting Apple computers for the past few months.
These addresses were used by whoever carried out the attack to control the malware and can be found in the malware code itself.
What he found was “a post on a Chinese Android developer forum discussing roughly the same code that is used in the malware.”
No malware, no anti-malware, no virus software updates and warnings.
"There is very little any [operating system] vendor can do against this sort of malware," Mogull says.
So activists started doing detective work, to see who was behind the malware.
Basically, the malware presents itself as a piece of antivirus software that is going to protect your machine.
The malware was identified by Russia's Kaspersky Lab and Israeli security firm Seculert.
These attacks had distinct similarities with the malware used against Sony.
You get the malware by clicking on a bad link in a set of search results.
Any software designed to do something that the user would not wish it to do, hasn't asked it to do, and often has no knowledge of until it's too late. Types of malware include backdoor, virus, worm, Trojan horse.
Malware typically affects the system on which it is run, e.g. by deleting or corrupting files on the local disks. Since Internet connections became common, malware has increasingly targets remote systems. An early example was malware consisting of a malicious e-mail attachment that targeted security flaws in Microsoft Outlook (the most common e-mail client) to send itself to all the user's contacts. A more recent kind of malware "recruits" the infected computer to become part of a botnet consisting of thousands of infected computers that can then be remotely controlled and used to launch DDoS attacks.
