Intel has disclosed a new variant of the Spectre and Meltdown security flaws in the chips that hackers may use to extract sensitive data from hundreds of millions of computers and mobile devices.

Intel is calling the new strain — Speculative Store Bypass (Variant 4) — and it is similar to the earlier flaw that taps into many of the same security vulnerabilities that were first revealed in January.

However, this time around it uses a different method to extract sensitive information, CNET quoted Intel as saying.

The new vulnerability also includes firmware updates for CPUs and Intel has already delivered microcode updates for Speculative Store Bypass in beta form to original equipment manufacturers.

Intel is classifying Variant 4 as a medium risk because many of the exploits it uses in web browsers, like Safari, Edge, and Chrome were fixed in the original set of patches, according to a blog post from the company.

Intel has promised that the patches would be rolled out broadly in the next few weeks. The firmware updates would set the Speculative Store Bypass protection to off-by-default.

“If enabled, we have observed a performance impact of approximately two-to-eight per cent based on overall scores for benchmarks,” Leslie Culbertson, Intel’s Security Chief, was quoted as saying.

As a result, end users would have to pick between security or optimal performance.

Spectre and Meltdown vulnerabilities have been causing problems to companies like Intel, Arm and AMD that are major producers of chips for computers, laptops and mobile devices.

While Meltdown impacts only Intel chips, Spectre affects all other chips, including ARM and AMD. The vulnerabilities allow attackers to read sensitive information on users’ CPU.

While companies like Intel, Apple and Microsoft have issued updates to patch the flaws, the fixes have not always worked as intended, sometimes causing computer problems.

Earlier this year, following the news of the bugs getting out, all major tech players such as Microsoft, Google, Apple, including Intel, released security patches to help protect users from potential data theft. (IANS)

If you’re lucky, you’ll never experience a fire in your home or place of business, but you can only trust luck so far. Because a fire can strike anywhere at any time, you need to be prepared by keeping your fire prevention supplies ready and your sprinklers well-maintained.

Fire Control Equipment

Any home or office can benefit from certain fire equipment. Any room that has people sleeping or which poses a potential fire hazard should have smoke alarms installed, preferably wired into the building’s electrical system so dead batteries don’t become a problem. Portable fire extinguishers should also be easily accessible in several areas of the building. Finally, in public places, exits should be clearly marked with signs that can be seen through a haze of smoke. You can get all of these supplies in one place. Control Fire Systems is a fire equipment supplier that provides alarms, extinguishers, control panels, signage, and much more.

Equipment Testing and Maintenance

Certain pieces of fire safety equipment need to be tested on a regular basis or have certain maintenance steps that need to be performed, usually every year. After installing your equipment, the experts at Control Fire Safety can also provide you with regular maintenance to make sure that everything works properly year after year. This includes such tasks as fire sprinkler inspection to make sure that your equipment meets all local and national fire codes. Because sprinklers need to be tested on occasion, Control Fire Systems also offers fire sprinkler system testing. While you can test your alarms and sprinklers yourself if you so choose, having professionals on hard for fire sprinkler system maintenance and other tasks helps to avoid any errors. In many cases, this regular maintenance can also save you money on building insurance premiums.
