Less than a day after Apple tackled the malware threats in OS X with an updated implementation of its malware detection technologies, the MacDefender malware developers have issued another variant that bypasses Apple’s definitions to root out and remove the malware, reports “CNET” (http://macte.ch/ocaIR).
“ZDNet” (http://macte.ch/BE1qX) says the new variant comes as a download called “Mdinstall.pkg” and will run without being detected by Apple’s new security implementations. It also shows that the malware developers are very actively trying to circumvent Apple’s efforts; the file’s time stamp shows that it was issued less than 8 hours after the security update for OS X was released.
Despite this new variant, Apple’s security update will still detect and remove older variants of the malware.
