Everything else is too old and outdated. 8000839818 D _nsysent The location will Vc Invest 7 Return After 2nd Year sysent can be found by disassembling the kernel and using one of the three functions that reference it: – unix_syscall – unix_syscall64 – unix_syscall_return For 10.
2 the sysent pointer will be located at 0xFFFFFF80008000D0 and the table located at 0xFFFFFF8000855840. Landon’s formula does not apply here. 8000846ed8 D _nsysent And sysent located at 0xFFFFFF8000842A40. This confirms Apple moving around the pointer between different releases. Notice that all previous values are from kernel at disk so no kernel ASLR slide is included. The slide value will be disclosed whenever it is being used in the examples. Another technique is described in The Mac Hacker’s Handbook , released in 2009 and targeting Leopard. 64 bits syscalls via the SYSCALL interface.
32 bits systems – it is used for 32 bits syscalls via SYSENTER. These are just a few possibilities to retrieve a valid address inside the running kernel and then find the start address of the kernel Mach-O header and sysent location. This alternative is easier and does not allocate new memory at the target. Do not forget to restore the original memory permissions. After so many words you are probably asking why not use copyout to copy from kernel to userland? Chapter 7 of and Chapter 13 of thoroughly describe the execution process in case you are interested in every detail. The above diagram presents many places where we can modify the new process memory and its Mach-O header. As previously mentioned, when dyld gains control it will parse again the Mach-O header so our modification is guaranteed to be used if made before dyld’s control. Code signing does not kill immediately the process.
The only puzzle piece left is which process should we use and how to kill it. Inside our new function we need to retrieve the necessary information to match the event we want to hide and return EINVAL or 0 in those cases. Macros exist to encode the integer for each available class. Grep’ing XNU source code for BSDDBG_CODE will show where kdebug is implemented in all BSD related functions. What are the conclusions from all this? If only the sysent table function pointers are modified by the rootkit, DTrace will be unable to directly detect the rootkit using syscall provider. The modified pointer will be copied by DTrace and return to it. DTrace is blind to the original function because it does not exist anymore in the table, only inside our modified version. If we modify the syscall handler as described in 2.
To unload the original rootkit is extremely easy – we do not need to execute any additional command, just return KERN_FAILURE from the start function and rootkit will not be loaded. The zombie rootkit already gained control before this so there is no problem and we avoid to execute a kextunload command. We are in a new phase of a very old war. Not everything over there is fully functional yet, and the internal links still point to this blog, and will for the indefinite future. So all the old material will be left here for archival purposes, with comments turned off. The following op-ed by Hanne Nabintu Herland concerns the Norwegian government’s persistent soft spot for the Palestinians.

It was originally published in Aftenposten, Norway’s largest newspaper, on January 15th, 2013, and has been translated by the author. Torgeir Larsen, a junior minister for the Norwegian Labor Party, admits in Norway’s largest newspaper Aftenposten on December 28, 2012, that Norwegian authorities closed their eyes to the realities of the Middle East. Too often they thought they were in the service of stability, but later found out that was not the case. Regardless, this acknowledgement of Norwegian naïveté must lead to tangible changes in foreign policy in order to be of real value. Especially since the current left-wing Labor government took office in 2005, the donations have exploded. What are these sums spent on? Recently the remuneration for suicide bombers was tripled.

The Hamas terrorist who killed 30 Israelis in 2002 by now receives 20,000 NOK a month, according to The Times of Israel last September the 9th. Those who have carried out the worst attacks against innocent civilians receive the highest pay. Intelligence and Terrorism Information Center figures from 2005 show that Palestinians have conducted 25,770 terrorist attacks, 147 suicide attacks leading to 1,100 dead Israelis and 7,500 wounded between 2000 and 2005. Fatah conducted 214 acts of terrorism in 2003-2004 alone, according to 2005 Terrorism Review. Many more foreign hostages than originally reported were taken by the Al Qaeda terrorists at the Amenas gas plant in Algeria. The Algerian government says that 100 out of 132 were freed, and some sources say that 30 or more hostages were killed.

As a follow-up to Tuesday’s post about the majority-minority public schools in Oslo, the following brief account reports the latest statistics on the cultural enrichment of schools in Austria. Vienna is the most fully enriched location, and seems to be in roughly the same situation as Oslo.
Many thanks to Hermes for the translation from Unzensuriert. The number of pupils with a first language other than German has doubled from 1995 to 2011. The doubling in the number of multilingual students is evident in virtually all provinces in Austria. In Carinthia, Lower Austria, Salzburg, Tyrol and Vorarlberg, the rise is a little lower, in Upper Austria is a bit higher, and in Burgenland it remained on average. The Styrian province is the only outlier, where the number of children with a different native language has tripled from about 5,000 to 16,000. The nationwide statistics conceals the dramatic developments in Vienna, because German is hardly spoken in the primary schools of the federal capital. 924 out of 1038 children have as their mother tongue something other than German.
