5G in US averages 51Mbps while other countries hit hundreds of megabits

Image
  Average 5G download speeds in the US are 50.9Mbps, a nice step up from average 4G speeds but far behind several countries where 5G speeds are in the 200Mbps t400Mbps range. These statistics were reported today by OpenSignal, which presented average 5G speeds in 12 countries based on user-initiated speed tests conducted between May 16 and August 14. The US came in last of the 12 countries in 5G speeds, with 10 of the 11 other countries posting 5G speeds that at least doubled those of the US. The US's average 5G speed is 1.8 times higher than the country's average 4G download speed of 28.9Mbps. User tests in neighboring Canada produced a 4G average of 59.4Mbps and a 5G average of 178.1Mbps. Taiwan and Australia both produced 5G averages above 200Mbps, while South Korea and Saudi Arabia produced the highest 5G speeds at 312.7Mbps and 414.2Mbps, respectively.    

Artificial intelligence

Image
                 Artificial intelligence , sometimes called machine intelligence, is intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals. Leading AI textbooks define the field as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals. Colloquially, the term "artificial intelligence" is often used to describe machines (or computers) that mimic "cognitive" functions that humans associate with the human mind, such as "learning" and "problem solving

Binary Code

Image
                    A binary code represents text, computer processor instructions, or any other data -using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, toeach character, instruction, etc. For example, a binary string of eight bits can represent any of 256 possible values and can, therefore, represent a wide variety of different items.              In computing and telecommunications, binary codes are used for various methods of encoding data, such as character strings, into bit strings. Those methods may use fixed-width or variable-width strings. In a fixed-width binary code, each letter, digit, or other character is represented by a bit string of the same length; that bit string, interpreted as a binary number, is usually displayed in code tables in octal, decimal or hexadeci...

AT&T, T-Mobile fight speed tests that could prove their coverage maps wrong.

Image
              AT&T and T-Mobile are fighting a Federal Communications Commission plan to require drive tests that would verify whether the mobile carriers' coverage claims are accurate. The carriers' objections came in response to the FCC seeking comment on a plan to improve the nation's inadequate broadband maps. Besides submitting more accurate coverage maps, the FCC plan would require carriers to do a statistically significant amount of drive testing. "In order to help verify the accuracy of mobile providers' submitted coverage maps, we propose that carriers submit evidence of network performance based on a sample of on-the-ground tests that is statistically appropriate for the area tested," the FCC proposal issued in July 2020 said.

Booze and cruise providers are the latest to be hit by ransomware scourge

Image
  Ransomware operators are continuing their blitz on corporations with deep pockets, with Jack Daniel’s distiller Brown-Forman and cruise line behemoth Carnival being two of the latest to be hit. The statement came after Bloomberg News reported that it had received an anonymous tip of a ransomware attack. A Dark Web site that claims to be run by members of the REvil strain of ransomware says it has obtained 1 terabyte of data from Louisville, Kentucky-based Brown-Forman. (In addition to producing Jack Daniel’s, Brown-Forman also owns Finlandia vodka and other spirits.) The site, which Ars isn’t linking to, said that stolen data included contracts, financial statements, credit histories, and internal correspondence of employees. Also included were screenshots of file structures and documents purportedly taken during the heist. Ars was unable to confirm the authenticity of the data. The Brown-Forman statement didn’t comment on the Dark Web site claims or the purported evidence. A Bro...

NSA and FBI warn that new Linux malware threatens national security

Image
  The FBI and NSA have issued a joint report warning that Russian state hackers are using a previously unknown piece of Linux malware to stealthily infiltrate sensitive networks, steal confidential information, and execute malicious commands. In a report that’s unusual for the depth of technical detail from a government agency, officials said the Drovorub malware is a full-featured tool kit that has gone undetected until recently. The malware connects to command and control servers operated by a hacking group that works for the GRU, Russia’s military intelligence agency that has been tied to more than a decade of brazen and advanced campaigns, many of which have inflicted serious damage to national security.

Snapdragon chip flaws put >1 billion Android phones at risk of data theft

Image
A billion or more Android devices are vulnerable to hacks that can turn them into spying tools by exploiting more than 400 vulnerabilities in Qualcomm’s Snapdragon chip, researchers reported this week. The vulnerabilities can be exploited when a target downloads a video or other content that’s rendered by the chip. Targets can also be attacked by installing malicious apps that require no permissions at all. From there, attackers can monitor locations and listen to nearby audio in real time and exfiltrate photos and videos. Exploits also make it possible to render the phone completely unresponsive. Infections can be hidden from the operating system in a way that makes disinfecting difficult.

More than 20GB of Intel source code and proprietary data dumped online.

Image
Intel is investigating the purported leak of more than 20 gigabytes of its proprietary data and source code that a security researcher said came from a data breach earlier this year. The data—which at the time this post went live was publicly available on BitTorrent feeds—contains data Intel makes available to partners and customers under NDA, a company spokeswoman said. Speaking on background, she said Intel officials don’t believe the data came from a network breach. She also said the company is still trying to determine how current the material is and that, so far, there is no signs the data includes any customer or personal information. “We are investigating this situation,” company officials said in a statement. “The information appears to come from the Intel Resource and Design Center, which hosts information for use by our customers, partners and other external parties who have registered for access. We believe an individual with access downloaded and shared this data.

British cyber expert pleads guilty to creating malware

Image
A British cybersecurity researcher credited with stopping a worldwide  computer virus  has pleaded guilty to developing  malware  to steal banking information. Federal prosecutors in Wisconsin and Marcus Hutchins' attorneys said in a joint court filing Friday that the 24-year-old agreed to plead guilty to developing malware called Kronos and conspiring to distribute it from 2012 to 2015. In exchange for his plea to those charges, prosecutors dismissed eight more. "As you may be aware, I've pleaded guilty to two charges related to writing malware in the years prior to my career in security," Hutchins said in a statement on his website. "I regret these actions and accept full responsibility for my mistakes. Having grown up, I've since been using the same skills that I misused several years ago for constructive purposes. I will continue to devote my time to keeping people safe from malware attacks." Hutchins faces up 10 years in prison but could receive a m...

Intel’s ‘Lakefield’ Hybrid CPUs: Where You’ll Find Them, What They Do, and What They Mean for the Future of PCs

Image
            Intel's new ‘Lakefield' processors mark a new chapter for the company, and could signal a huge shift in the way that future PCs are designed and developed. Intel has struggled for several years now, first with a poorly executed plan to migrate from 14nm to 10nm manufacturing, and then with continual shortages of products in the market, leading to price spikes. Intel had its roadmaps set back by many years, and had to fall back on iterative revisions to its 14nm products to fill the gap over the past several generations. Meanwhile, competitor AMD has seen a massive resurgence in the desktop and server markets, and Qualcomm has begun offering chips for laptops. Even Apple just recently announced a shift away from Intel chips in order to develop more versatile devices in the future.
