The root of the infection routine is based around hijacking configuration files in OS X that are read and executed when programs are run.
#PACKET PEEPER PASSWORD#
Unfortunately at this point there is nothing to stop the infection, and whether or not a password is supplied only changes the mode of infection.
#PACKET PEEPER UPDATE#
This is where users will see an alert about a software update and will be prompted to supply their passwords. Once the malware and the filter are downloaded, the malware is run to infect the system. The first is the main part of the malware that performs the capture and upload of personal information, and the second is a filter component that is used to prevent the malware from running unless specific programs like Web browsers are being used. When the jupdate program executes, it will connect to a remote server and download a payload program that is the malware itself, and which consists of two components. Many malware programs use this behavior, as was seen in others such as the Tsunami malware bot. If these tools are found, then the malware deletes itself in an attempt to prevent detection by those who have the means and capability to do so. Developer/Applications/Xcode.app/Contents/MacOS/Xcode In order to avoid detection, the installer will first look for the presence of some antivirus tools and other utilities that might be present on a power user's system, which according to F-Secure include the following: jupdate program whenever the user is logged in. In addition, the Java applet will write a launcher file named something like "", "", "" or even "ist" to the current user's ~/Library/LaunchAgents/ folder, which will continually launch the.

rserv, and the period in front of it makes it appear hidden in the default Finder view. When you encounter the malicious Web page containing the malware and have an unpatched version of Java running on your system, it will first execute a small Java applet that when run will break the Java security and write a small installer program to the user's account.
#PACKET PEEPER CODE#
The Flashback malware injects code into applications (specifically Web browsers) that will be executed when they run, and which then send screenshots and other personal information to remote servers.

So far, it is estimated to have infected over 600,000 Mac systems worldwide, with the majority in the U.S.
#PACKET PEEPER INSTALL#
However, the threat quickly morphed into a more serious threat by taking advantage of unpatched security holes in Java ( which Apple has since addressed) to install on a Mac running Java by merely visiting a malicious Web page and not requiring any user attention. The latest malware to hit OS X has been the Flashback scam, which initially started as a fake Flash player installer application that was relatively easy to avoid. Another scam was the DNSChanger malware that affected millions of PC systems worldwide, and which ultimately directed affected systems to malicious Web sites, and like the MacDefender malware tried to get people to offer personal information. This scam morphed quite rapidly as it tried to avoid detection and continue coercing people to offer personal information. One of the first was the MacDefender fake antivirus scam, which had people issuing credit card information out of fear their systems were infected. While OS X was relatively void of malware for the first 10 years of use, recently malware scares have cropped up that have affected a significant number of Mac systems.
