A number of people are reporting yet another MacDefender variant this morning. This time, it’s named MacProtector, but it sounds like the method of operation is the same. Mac users should be on their guard against an attack of this type, regardless of the name. (If you haven’t been following along, see all my coverage of the MacDefender trojan.)
If anyone can send me a link where MacProtect can be found, so I can verify that it behaves the same as MacDefender, please do!
Edit: Thanks to pieinoz for pointing me to just the right search terms to use on Google Images to find MacProtector. As I suspected, it does appear to be nothing more than a variant of MacDefender. After updating my ClamXav definitions this morning, I found that it will detect both MacSecurity and MacProtector.
