Hacking a pacemaker

In the last few days I have read a couple of pieces which quote the William Gibson dictum “the future has already arrived, it’s just not distributed evenly”. Confirmation that we are indeed living in a science-fiction story arrived today in the shape of a message on the Full Disclosure list: hacking a pacemaker. Security researcher Gadi Evron cites a report in the NYT.

” The threat seems largely theoretical. But a team of computer security researchers plans to report Wednesday that it had been able to gain wireless access to a combination heart defibrillator and pacemaker.

They were able to reprogram it to shut down and to deliver jolts of electricity that would potentially be fatal . if the device had been in a person. In this case, the researcher were hacking into a device in a laboratory. “

What a great way to assassinate somebody….

Log Buffer #88: a Carnival of the Vanities for DBAs

Welcome to the 88th edition of Log Buffer, the weekly review of database blogs.
SQL Server
To begin, Simon Sabin, on SimonS Blog, offers the proposition: SQL Server tools suck, do you agree? He elaborates, “When I moved from Oracle 7 to SQL Server 6.5 I was amazed at the tools you got with SQL Server. […]

A default password script and a cracker helper script

I subscribe to the pentest list on security focus and a recent thread around Oracle password crackers threw up links to a couple of small scripts that are worth a mention simply to keep a record of them here. The….[Read More]

Visiting Muhammad Ali

After arriving in Cairo I immediately went to see if the my friend Muhammd Ali is still in living in his place as before 13 years.  I had been living in his place for a while in the 90s.
 Muhammad is an internationally recognized artist and has been painting since more than 25 years now. He had […]

Howto find CPU is dual/quad core in HP-UX

How to check HP-UX CPU is dual/single core on Integrity servers

HP-UX Itanium integrity servers come with dual to quad core processors. If you have inherited these server and you haven’t build them from scratch then it’s get hard to find if you have dual core or quad core processor on HP Integrity servers. As of now there is no command available on HP-UX 11iv2 which can be used to check processor cores. I have several rx6600 Integrity server running HP-UX 11i and running top, machinfo and mpsched commands only return number of cpu as 4:

root@rx6600:/> mpsched -s

System Configuration

=====================

Locality Domain Count: 1

Processor Count : 4

Domain Processors

—— ———-

0 0 1 2 3

Running mpsched shows Processor count as 4, but this doesn’t tell is there is single quad core processor or 2 dual core processors. I am giving it second try and ran machinfo which isn’t helpful either in determining CPU (processor) cores:

root@rx6600:/> machinfo

CPU info:

Number of CPUs = 4

Clock speed = 1595 MHz

Bus speed = 532 MT/s

CPUID registers

vendor information = “GenuineIntel”

processor serial number = 0×0000000000000000

processor version info = 0×0000000020000704

Here is the top output showing 4 processors but no information on processor core (dual or single?) :

System: rx6600 Thu Mar 13 09:22:51

Load averages: 0.02, 0.02, 0.01

213 processes: 181 sleeping, 31 running, 1 zombie

Cpu states:

After scratching my head for several hours I was able to find the information when I was rebooting the HP-UX server and start looking into EFI option, so if you are able to boot your server at some point press any key to interrupt the boot cycle and access EFI boot manager.

From EFI boot manager select “System Configuration

=>System configuration select “Advanced System Information

=> from Advanced system information select “Display All information

PROCESSOR MODULE INFORMATION

Looking in the output its clear now that this HP-UX server is having 2 dual core CPU as listed in next column. The number of Logical CPU is 2 for each CPU module.
