Google Chrome 64-bit Browser Finally Released As a Stable Version

635 123 Reddit0 1 821

Along with the release of Chrome 37 for Windows, Mac, and Linux, Google today also released a long-awaited 64-bit stable version of its Chrome browser for Windows systems. The company has been working on the 64-bit support for Windows 7 and Windows 8 since June.

Back in June, Google first released Chrome 64-bit only in the browser’s Dev and Canary channels. Then in July, the beta channel received the same update, and now, finally Chrome 64-bit is available in the stable channel.

The new 64-bit version of Chrome offers three main advantages:

Speed
Security
Stability

Therefore, for those of you on a compatible 64-bit system, this new version will offer faster performance as well as security and stability enhancements in comparison to 32-bit version. But, Chrome 64-bit is still an opt-in process. So, if you want to take advantage of it, you can hit the new “Windows 64-bit” download link over at google.com/chrome.

SPEED ENHANCEMENT

Google claims that certain media and graphics workloads in particular are faster in speed with Chrome 64-bit version. The company gives an example of VP9 video decoding — used for some YouTube high-definition streams — being 15 percent faster compared to 32-bit variant as a result, said Chrome team programmer Will Harris in a blog post.

The 64-bit of Chrome version is faster because it leverages optimizations made to processor and compilers, has a more modern instruction set compared to the 32-bit edition, and a calling convention that allows more function parameters to be passed quickly by registers.

SECURITY ENHANCEMENT

The security of the systems have also been improved in the 64-bit version by having access to a larger pool of memory.

Since, Windows has a built-in security feature called ASLR (Address Space Layout Randomization) which makes bug exploits harder to write by randomizing the location of items such as DLLs in memory. Because the new version have much more memory available, bug exploits are difficult to create, and with more memory to work with, the process becomes even harder.

STABILITY ENHANCEMENT

The Search engine giant also says that with 64-bit version of the browser, stability has also improved, being "twice as stable" as its 32-bit equivalent.

While testing beta versions of Chrome 64-bit, the development team found that the Chrome browser crashes around half as often as the 32-bit version when processing web content.

WHATS WRONG WITH 64-BIT VERSION OF BROWSER?

As every new feature comes with some negative impacts as well. Chrome 64-bit version might has a few possible drawbacks, of which the most significant one being no support for 32-bit NPAPI plugin that was found in the 32-bit browser

This means that some browser plugins, including both Silverlight and Java, will not work in the new version. Google intends to remove 32-bit NPAPI support at some point in the future, so this drawback will not be permanent.

CHROME 37 — WHAT’S NEW?

The Chrome 37 update also marks the stable release for Windows, Mac and Linux, the official change log provided by Google lists the following tweaks:

DirectWrite support on Windows for improved font rendering.
A number of new apps/extension APIs.
Lots of under the hood changes for stability and performance.

The Chrome 37 update will happen automatically for most users, however if you want to get the 64-bit version, you will have to manually download the variant from the browser's website.

HardCoded Backdoor Found in China-made Netis, Netcore Routers

Routers manufactured and sold by Chinese security vendor have a hard-coded password that leaves users with a wide-open backdoor that could easily be exploited by attackers to monitor the Internet traffic.

The routers are sold under the brand name Netcore in China, and Netis in other parts of the world, including South Korea, Taiwan, Israel and United States.

According to Trend Micro, the backdoor — a semi-secret way to access the device — allows cybercriminals the possibility to bypass device security and to easily run malicious code on routers and change settings.

Netis routers are known for providing the best wireless transfer speed up to 300Mbps, offering a better performance on online gaming, video streaming, and VoIP phone calling.

The Netcore and Netis routers have an open UDP port listening at port 53413, which can be accessed from the Internet side of the router. The password needed to open up this backdoor is hardcoded into the router’s firmware.

All of the routers – sold under the Netcore brand in China and as Netis outside of the country – appear to have the same password, Tim Yeh, threat researcher at the security firm, says warning that the backdoor cannot be changed or disable, essentially offering a way in to any attacker who knows the “secret” string.

Using the backdoor, hackers could upload or download hostile code and even modify the settings on vulnerable routers in order to to monitor a person’s Internet traffic as part of a so-called man-in-the-middle (MitM) attack.

By attempting MitM attack, a potential attacker could intercept users’ internet communication, steal sensitive information and even hijack sessions.

The researchers scanned the Internet and had indicated that millions of devices worldwide are potentially vulnerable.

“Using ZMap to scan vulnerable routers, we found more than two million IP addresses with the open UDP port,” Yeh wrote in a blog post. “Almost all of these routers are in China, with much smaller numbers in other countries, including but not limited to South Korea, Taiwan, Israel, and the United States.”

Exploiting this flaw is not too difficult, as a simple port scan can reveal the open UDP ports to anyone using such an online tool.

In addition, Trend Micro also found that a configuration file containing a username and password for the web-based administration panel on the router is stored with no encryption protection, allowing an attacker to download it.

“Users have relatively few solutions available to remedy this issue. Support for Netcore routers by open source firmware like dd-wrt and Tomato is essentially limited; only one router appears to have support at all. Aside from that, the only adequate alternative would be to replace these devices,” advises Yeh.

Users can determine whether their router is impacted here.
