Scraps And Patches Mac OS

If your computer seems to be working fine, you may wonder why you should apply a patch. By not applying patches, you might be leaving the door open for malware to come in.

Benefits and key features

Free ARIES Solutions Mac OS X 10.6/10.7 Version 1.2.3 Full Specs. Average User Rating: 2 User Votes 1.0. For our next update we are planing to integrate Bonjour support. This will allow you. If you haven't updated to Catalina yet, read on to find out how to update to Catalina or Mojave from High Sierra, Sierra, El Capitan, Yosemite, or even older version of Mac OS X below.

Malware will exploit software flaws on your computer in order to do its work. Knowing how to patch your computer automatically while at MIT can prevent major headaches. IS&T can help you set up automatic patches so that you don't even have to think about it.

Features include:

  • Security updates for Mac OS and Windows
  • New releases of IS&T provided software
  • MIT Windows Automatic Update Service (WAUS)

Requirements

Download anti-virus, backup, and security software from the Software Grid, and subscribe to automatic updates. (MIT certificates required)

Getting started

Microsoft

  • Turn on the Automatic Updates feature in your Windows operating system. You will be notified of any updates before downloading them or automatically installing them. You set the frequency of notification.
  • Subscribe instead to the MIT Windows Automatic Update Service (WAUS) to receive a more conservative selection of the most critical security updates from Microsoft.

Apple

  • Mac OS X automatically checks for software updates. Choose a different schedule (set weekly by default) or check manually. If you see an update that you will never use, you can deselect it from the update menu.

Linux

  • IS&T provides an update service for Red Hat Enterprise Linux machines. Other Linux systems are not as simple to patch because of the nature of Linux software and its many distributions. Each distribution has a different method of patching. Learn more about the Red Hat Network update service.

Mac OS X Kernel Patches
formerly MAC Spoofing on the Mac

table of contents

background

An essential component of penetration testing and network wargames is theability to specify arbitrary MAC addresses. This ability is also requiredfor the implementation of certain kind of protective security functionalitysuch as proxy ARP, in conjunction with tools such as arpcatch. It'smy understanding that ARP spoofing is even being used in some experimentalintrusion detection technologies.

Note that this patch is not a tool in and of itself; it merely extends othertools and APIs, and actually requires some knowledge to use.(Read: spare me your accusations of feeding the skriptkiddies until you know what you're talking about.)

Like other BSD-derived codebases, Mac OS X and Darwin kernels like tometiculously stick the hardware address into the source field ofeach ethernet header. The following Darwin / Mac OS X kernel patch removesthat tendency for AF_UNSPEC packets, allowing injected packets to forge thatfield in the header.

Also supplied below are a RAW4ALL patch, so you don'talways have to be root to use raw sockets, and a FORCE_VERBOSE patch toforce verbose output at boot time without having to press Option-V.Note that the FORCE_VERBOSE patch is not necessary with some Apple-suppliedtarballs and CVS checkouts.

In recent days, Jeff Nathan has put together a less kludgey patch that fixesall the known issues; this is linked to below. These patches have been testedand verified with up to OS X 10.3 (Darwin 7.x) and verified to allow MACspoofing with ethernet cards as well as wireless cards.

OS X 10.4.x (Darwin 8.x) kernel sources appear to require no modification inorder to spoof MAC addresses.

installation

Building a Darwin kernel is a little different than building one in Open, Free,or NetBSD, so I've included brief directions. If you're a seasoned Darwin useror developer, you likely have all the tools ready to go to build xnu,the source tree for the Darwin kernel. If so, skip ahead to step 5. However,if you've just installed Mac OS X, you likely don't have everything you need tocompile kernels, and there are a few steps to go through:
  1. Grab and install the developer tools from Apple's developer site if youhaven't already.
  2. make and make installrelpath from thebootstrap_cmds project.
  3. make and make install the Libstreams project.
  4. Unpack the cctools project,
    • make all in the libstuff directory,
    • make macos_all in the misc directory andinstall seg_hack.NEW as /usr/local/bin/seg_hack,
    • make macos in the libmacho directory and installotmp_obj/libmacho_static.a in /usr/local/lib, and
    • make kld_build in the ld directory and installstatic_kld/libkld.a in /usr/local/lib.
  5. [Mac OS X 10.3 / Darwin 7.x and above] Build kextsymboltool from thekext_tools project and install in /usr/local/bin. You willneed to pull in headers from the IOKitUser project andcctools.
  6. Build the xnu project with the patches of your choice below, theproper options in bsd/conf/MASTER, and the directions in theREADME supplied by Apple in the xnu tarball. Installyour new kernel at /mach_kernel. It goes without saying that youshould back up your old one first.
  7. Reboot your box.
I've encountered or heard about a variety of very different compile-timeproblems, depending on the version of the operating system and the developertools you're using; if this is the case, try fiddling around withgcc_select.

The directions above, by the way, are intentionally not very thorough. I'vetried to write these directions for those who will be able to make useof this patch. In other words, if you can't navigate through the directionsabove, you probably shouldn't be messing with this patch. Either way, pleaseuse it responsibly.

Even if you are using CVS, one of the patches above will likely work withyour kernel source tree.

I have decided that these source patches are trivial enough that they do notrequire integrity hashes. However, please review what you download beforeapplying them to your source tree.

Also, I'm pretty sure all these source patches are all subject to theApple Public Source License.

known issues

Jeff Nathan's patch should fix all the known issues with the originalETHERSPOOF patch. Do not use his patch with any of the ETHERSPOOFpatches above. They are incompatible, and his patch is better.

Patches called 'ETHERSPOOF' above break the DHCPclient thanks to the funky DLILization of the kernel, and though I have yet tosee them cause problems getting an address personally, I have received reportsand seen the cause of the problem, empty source ethernet address fields in theheader.
