Stephen Hawking: R.I.P

He was the outstanding theoretical physicist of our time. His lifetime disease was no handicap for his work on quantum physics and black holes, it gave him always enough room and time to think and rethink.
Because of his popular and outstanding work he had a celebrity status and appeared in different TV shows like The Simpsons, The Big Bang Theory and of course in Star Trek: The Next Generation playing a poker game with Issac Newton and Albert Einstein. Einsteins work an the base theories and model made it possible for Hawking to continue his work in detail. His relation with Einstein made him die on the exact same day as Einstein was born, the 14th of march.

WannaCry on Samba = SambaCry

After the WannaCry attack on Windows it was the question if the open source implementation SAMBA may have a similar vulnerability and in fact it has as currently reported: CVE-2017-7494 Affected are all versions from version 3.5.0 onwards. Patches are available and every distribution should have an update ready in their repos. A workaround is to add the parameter

nt pipe support = no

to the [global] section of the smb.conf file.

This years financial analyst day had more product previews and launches than any before. Even the AMD Crew now had 6 speaker compared to 4 in the last year. The big news on this day was the introduction of the Server Epyc CPU code name “Napples” (32 Cores 64 Threads). This also means that good known Opteron brand is now history. Another highlight was the introduction of the upcoming premium desktop CPU AMD Ryzen 9 Threadripper (16 Cores 32 Threads). In the 2nd half of the year is also the launch of the Ryzen Mobile APUs with integrated Vega Graphics.

WannaCrypt Ransomware Attack

The WannaCry/WannaCrypt Ransomware attack successfully compromised tons of systems already by using the classic e-mail attachment vector and the 2nd vector is to use the vulnerable SMB protocol to attack machines in internal networks to infect them as well.

To fix the SMB issue Microsoft already released an update in march 2017, security bulletin MS17-010.

Description:
This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker sends specially crafted messages to a Windows SMBv1 server.

Microsoft now also released an update for Windows XP and Windows Server 2003 (KB4012598) to fix the issue. Automatic Updates should find and install the updates or you can find them in the Microsoft Update Catalog. Microsoft has some more information about this issue on the MSRC team blog.

Microsoft kills future security updates for Windows 7 on modern hardware

On the April 2017 patch day Microsoft has released two security bulletins KB4015549 and KB4015546 that will block future security updates on Windows 7 in case a newer processor is detected that is part of the following CPU Families: Intel KabyLake, AMD Bristol Ridge and AMD Ryzen.
The block mechanism is enforced by the new Windows Update Agent Version 7.6.7601.23735 this also prevents manually update installs using the .msu package. After installing the Microsoft Updates from above a UI nag screen will show up that reminds you of the non supported hardware, even when the system is working ok.

The error in the log file looks like this:

c98 Agent WARNING: WU client failed Searching for update with error 0x80240037
f24 AU >>## RESUMED ## AU: Search for updates [CallId = {692C634C-461A-46AC-82FD-16C025C65F22}]
