Don’t sit down! Patch ALL Windows AGAIN! Microsoft fixes THIRD Hacking Team hole

21 07 2015

It’s 2015, and bad font files in webpages will still pwn you.

All supported versions of Windows now need to be patched – again – to fix an urgent remote code-execution vulnerability emerging from the ongoing Hacking Team hack fiasco.

Details of the vulnerability were found and reported to Microsoft by security researchers poring over internal memos leaked online from spyware-maker Hacking Team. This follows an elevation-of-privilege hole in Windows and a remote-code execution bug in Internet Explorer 11 that were also uncovered from the Hacking Team files, and patched last week by Microsoft.

This latest serious security flaw (MS15-078) lies within the Windows Adobe Type Manager Library, and can be exploited by attackers to hijack PCs, infect them with malware, and so on. A victim who opens a document or even a webpage that contains a malicious embedded OpenType font file can be attacked thanks to this vulnerability.

Normally, security patches for Microsoft software are released as a bundle on the second Tuesday of every month. Today, the Redmond giant felt compelled to issue an emergency update for its operating system.

The security flaw is potent because Microsoft runs its font drivers in kernel mode, meaning if one of the libraries is fed bad data, the whole operating system can be compromised. Microsoft explained in an advisory:

French police move from Windows to Ubuntu Linux

7 10 2013

Summary: The big reason the French Gendarmerie made the Linux move? It saved them 40 percent in total cost of ownership over Windows.

There are many reasons to switch to a Linux desktop from Windows. Better security; not having to worry over possible built-in privacy leaks; and, last but never least, Linux is cheaper… a lot cheaper.

That’s the big reason why the Gendarmerie, which with the Police Nationale, serves France as a national police force, has been slowly, but surely moving to a customized version of Ubuntu Linux, from Windows XP.

In an European Union report for government administrators, Major Stéphane Dumond of the French Home Office is reported to have said at the Evento Linux conference that, “Using an open-source desktop lowers the total cost of ownership (TCO) by 40 percent in savings on proprietary software licenses and by reducing costs on IT management. Using Ubuntu Linux massively reduces the number of local technical interventions.”

ZDNet – Is your PC slowing down?

21 07 2010

Li este artigo com algum espanto tendo em conta a sua origem – tanto a ZDnet como a PCWorld parecem divisões propagandistas da Microsoft, juntamente com a Gartner que já publicou estudos a favor da MS que foram prontamente comprovados que não eram imparciais e alguns vieram-se a saber que foram mesmo “encomendados” pela Microsoft. Mas o Tempo da campanha “Get The Facts” da Microsoft já lá vai e com o crescimento de plataformas Open Source como o Android, Meego entre outras, o Linux está cada vez mais presente nas mãos de muitos que apesar de tudo desconhessem esse facto.

Excerto do Artigo:


Take anybody that uses a computer, and one of the most common topics of discussion is the fact that the PC keeps slowing down over time. But take a look at the root cause of the slowdown and you may discover some interesting finds. I’ve heard everything from “my computer is getting tired” to “the hardware is wearing out”. Well, there is really little truth to those statements. First, PC hardware does not tire out.

The cause of general PC slowdown is the software running on the PC itself. And now that we have different operating systems available, you will find different results with each. Typically, Windows is one of the worst operating systems known to slow down over time. And there are many reasons for this. Take a look at the solutions on the Internet and you will soon find out why it is prone to this.

What you may not have heard is that other operating systems like Linux are not prone to these slowdown issues. I’ve seen installations of Linux that are over 7-8 years old, and they run as good as the day they were installed. How can this be? First, Linux is extremely good at keeping itself cleaned up.

Defragmenting the hard drive. It’s hard to believe that even Windows 7, the latest operating system from Microsoft, is still prone to this problem. The NTFS filesystem (used by Windows NT and up) has other quirks, but it seems to slowly get fragmented and requires defragmenting from time to time

So in the end, we can see that some operating systems (Windows) do not attempt at being efficient and therefore tend to bog down over time. While others (Linux) automatically keep themselves tidy and clean along the way, and avoid the issues altogether. These problems can be compounded on server systems, where performance can affect more than just one user.

Consider Linux for Secure Online Banking

12 08 2009

1720-5299Neste artigo Michael Horowitz opina sobre porque razão se devem utilizar máquinas a correr Linux para aceder a plataformas de Home/Online Banking.

Exemplifica também uma série de boas práticas para os utilizadores de sistemas Windows de como manter o sistema a correr o mais limpo possível com recursos a programas de detecção e remoção de Software Malicioso, como a testes Online de detecção de vulnerabilidades.

Do you make online financial transactions from a Windows computer? If so, you may want to re-visit that decision.

It’s a given that almost all malicious software targets Windows. In my opinion, while it is possible to secure a Windows computer, the process is too hard, too time-consuming and/or technically over the head of most people.

A recent article at WashingtonPost.com described multiple organizations whose bank accounts were emptied by malicious software on their Windows computers. In one case, the Clampi Trojan sat undetected for a year on the computer of the Controller of a small business, before it decided to make withdrawals from their bank account.

According to recent news reports, “Fraudsters are taking advantage of the widely used but obscure Automated Clearing House (ACH) Network in order to pull off their attacks.” Businesses don’t have the same safeguards as consumers from this type of theft. Both articles describe serious losses and lawsuits.
