OSX/MaMi Virus – How Did I Get It

The primary methods by which the OSX/MaMi virus has been detected by security experts to be spread is believed to be via spammed URLs that may cause a drive-by download which could ultimately lead to the infection. These URLs may be caused if you have clicked on an add from a low-reputation website or even as a result of having adware to be installed on your Mac.

But this may not be the only scenario in which an infection by OSX/MaMi could unfold. The virus may also be sent to you in the form of a seemingly important e-mail attachment, in an e-mail that seems to be coming from a reputable company, like FedEx, DHL, PayPal or even your own bank. These e-mails often contain the infection files of viruses, like OSX/MaMi and these files may pose as:

  • Invoices.
  • Receipts for orders.
  • Reports for security problem with your account.

OSX/MaMi – More Information

  • Passwords that may be saved.
  • Your unlock code or other codes.
  • Your financial information.
  • Your browsing details.
  • System data of your Mac.What apps may be installed.
  • >

This information may then be transferred to the C2 server of the OSX/MaMi virus with the main goal of stealing it.

Another activity which is done by the OSX/MaMi virus is to change your DNS address to perform man-in-the-middle attacks. This may bring a world of problems to your Mac, because it’s outcome may be the severe infection of your Mac with all sorts of other viruses.
