How to Get Started With React – A Beginner’s Guide

React (also known as React.js or ReactJS) is a free and open-source front-end JavaScript framework for creating UI components-based user interfaces. React is maintained by Meta (previously Facebook) and a community of individual developers and organizations. According to the 2021 Stack Overflow’s developer’s survey [https://insights.stackoverflow.com/survey/2021#section-most-popular-technologies-web-frameworks] , React.js surpassed jQuery

Russia’s Sandworm hackers attempted a third blackout in Ukraine

More than half a decade has passed since the notorious Russian hackers known as Sandworm targeted an electrical transmission station north of Kyiv a week before Christmas in 2016, using a unique, automated piece of code to interact directly with the station’s circuit breakers and turn off the lights to a fraction of Ukraine’s capital. That unprecedented specimen of industrial control system malware has never been seen again—until now: In the midst of Russia’s brutal invasion of Ukraine, Sandworm appears to be pulling out its old tricks.

On Tuesday, the Ukrainian Computer Emergency Response Team (CERT-UA) and the Slovakian cybersecurity firm ESET issued advisories that the Sandworm hacker group, confirmed to be Unit 74455 of Russia’s GRU military intelligence agency, had targeted high-voltage electrical substations in Ukraine using a variation on a piece of malware known as Industroyer or Crash Override. The new malware, dubbed Industroyer2, can interact directly with equipment in electrical utilities to send commands to substation devices that control the flow of power, just like that earlier sample. It signals that Russia’s most aggressive cyberattack team attempted a third blackout in Ukraine, years after its historic cyberattacks on the Ukrainian power grid in 2015 and 2016, still the only confirmed blackouts known to have been caused by hackers.

ESET and CERT-UA say the malware was planted on target systems within a regional Ukrainian energy firm on Friday. CERT-UA says that the attack was successfully detected in progress and stopped before any actual blackout could be triggered. But an earlier, private advisory from CERT-UA last week, first reported by MIT Technology Review Tuesday, stated that power had been temporarily switched off to nine electrical substations.

How to Update Node and NPM to the Latest Version

Node is a runtime environment that allows developers to execute JavaScript code outside the browser, on the server-side. NPM, on the other hand, is a package manager for publishing JavaScript packages (also known as Node modules) to the npm registry [https://www.npmjs.com/]. You can also use it to install packages to

US seizes RaidForums, the “go-to” site for hackers selling stolen login details

The US has seized the domain of what it calls “one of the world’s largest hacker forums” and indicted its founder, the Department of Justice announced Tuesday. A notice on RaidForums.com says the domain was seized by the FBI, Secret Service, and Department of Justice. Europol and law enforcement agencies from Sweden, Romania, Portugal, Germany, and the UK were also involved.

RaidForums founder and chief administrator, Diogo Santos Coelho, a 21-year-old from Portugal, was arrested in the UK on January 31 and is in custody pending the outcome of extradition proceedings. The case in US District Court for the Eastern District of Virginia was unsealed Monday. Two accomplices were also arrested, according to Europol.

Founded in 2015, “RaidForums served as a major online marketplace for individuals to buy and sell hacked or stolen databases containing the sensitive personal and financial information of victims in the United States and elsewhere, including stolen bank routing and account numbers, credit card information, login credentials and social security numbers,” the DOJ said. As a Vice article noted, the seizure announcement “caps off weeks of speculation of what may have happened to the site, which mysteriously became unresponsive around the end of February.”

Developer discovers new Mac mini model in Studio Display firmware file

Apple’s Mac Studio just came out, but there’s some good news for anyone waiting on a refresh to Apple’s cheapest Mac desktop. Developer Steve Troughton-Smith uncovered a reference to an as-yet-unannounced “Macmini10,1” model identifier in a firmware file for the Studio Display, implying that Apple is testing a new Mac mini internally and that it could be released sooner rather than later.

The presence of an unreleased Mac mini model identifier in a firmware file tells us little about the machine, beyond the fact that the hardware physically exists somewhere inside Apple. But we can say with some confidence that it’s meant to be a new generation of Mac mini, rather than a revision of the current design—Apple uses “Macmini9,1” for the current mini, and “Macmini8,1” for the final Intel model from 2018.

Apple is expected to refresh the MacBook Air, Mac mini, and 13-inch MacBook Pro with a next-generation Apple M2 processor sometime this year. The M1 and all its variants use the CPU architecture from 2020’s A14, codenamed “Firestorm” for the performance cores and “Icestorm” for the efficiency cores. The M2 will likely update that architecture and could possibly add more GPU cores as well.

Vivo X Fold turns up the heat on Samsung’s foldables line

Vivo X Fold turns up the heat on Samsung’s foldables line

The latest foldable smartphone hitting China is the Vivo X Fold. This is the first foldable you could call a 2022 flagship, with a Snapdragon 8 Gen 1 SoC. The phone retails in China for 8,999 yen, or about $1,400.

This device looks as good as a Galaxy Z Fold 3, with an 8-inch, 120 Hz, 2160×1916 OLED as the main interior display and a 6.53-inch, 120 Hz, 2520×1080 OLED display on the outside. Besides the new Qualcomm chip, it has 12GB of RAM, 256GB of storage, an Android 12 build, and a 4,600 mAh battery.

For most of our non-Chinese readers, the most interesting thing about Vivo making a foldable is that it’s a BBK Electronics company, along with Oppo, OnePlus, Realme, and iQoo. BBK companies all share the same parts and engineering, so the hope is that OnePlus will someday pick through the BBK parts bin and bring a foldable to a wider audience. Oppo already took a swing at the foldables market with the Find N in December, and both that phone and the Vivo X Fold show how close China is to catching up with Samsung’s foldable lead.

EVE Online’s success shows why gaming doesn’t need NFTs

In-game ships and structures like these have real value to <em>EVE Online</em> players even without NFTs.

Enlarge / In-game ships and structures like these have real value to EVE Online players even without NFTs.

Nearly 19 years after its launch, EVE Online still has one of gaming’s most robust virtual economies, as the game’s detailed monthly economic reports attest. So when developer CCP says it has “no plans to add blockchain technology into EVE Online… for the foreseeable future,” it should probably cause proponents of crypto gaming to wonder why.

In a Monday blog post, CCP CEO Hilmar Pétursson wrote that the company is always “exploring new technologies and new possibilities” to help fulfill its mission to have “the EVE Universe outlive us all: EVE Forever.” But while he said that blockchain tech has “a lot of untapped potential,” he noted that there is “a lot of work needed before [blockchain is] ready for EVE-scale games.”

Pétursson leaves CCP a bit of wiggle room, though, by clarifying that non-fungible tokens will be absent from Tranquility, the main server cluster that serves as the home for the game’s global player base. So CCP may still experiment with blockchain technologies on the Chinese Serenity servers or mobile spinoff Eve Echoes, which have their own completely separate economies and player bases [Note: This portion initially misstated the nature of some alternative EVE Online servers. Ars regrets the error].
