Samsung Electronics Vice-Chair Jay Y. Lee received a presidential pardon Friday for his role in a 2016 political scandal, a move the South Korean government says is necessary so the country's largest chaebol can help steady the national economy.

“In a bid to overcome the economic crisis by vitalizing the economy, Samsung Electronics Vice Chairman Lee Jae-yong… will be reinstated,” the Korean government stated in a joint press release from its ministries, according to Bloomberg News .

Lee, 54, known as Lee Jae-yong in Korea, was arrested in February 2017 on charges that he was complicit in Samsung paying millions in bribes to various organizations tied to a presidential advisor in order to win favor for an $8 billion merger of two Samsung Group units. In August 2017, Lee was convicted of perjury, embezzlement, hiding assets outside the country, and being one of five Samsung executives who paid $6.4 million in bribes to ex-South Korean President Park Geun-hye.

    Samsung Galaxy Watch 5 adds battery life, screen strength, and temperature sensor

Samsung announced the Galaxy Watch 5 and Watch 5 Pro on Wednesday, giving its round, semi-rotating Wear OS watches new looks, a tougher screen material, and—for reasons the company can only vaguely explain—an infrared temperature sensor.

Neither the $280 Watch 5, available in 40 or 44 mm sizes, nor the 44 mm $450 Watch 5 Pro has a physically rotating bezel, a distinguishing Galaxy Watch feature that was limited in the last generation to the higher-end Watch 4 "Classic" (which is still available). Instead, both models have capacitive touch bezels, so you can run your finger around the edge to scroll.

Both Galaxy Watch 5 models look just like the official 3D rendering leaks scooped up by Evan Blass at 91Mobiles . Their displays have been upgraded to sapphire crystal, which should help bolster the Watch 5's flat-front display. Samsung says this material is "60 percent harder" than prior watch displays.

    Samsung Encryption Flaw

    news.movim.eu / Schneier · Wednesday, 2 March, 2022 - 20:45 · 1 minute

Researchers have found a major encryption flaw in 100 million Samsung Galaxy phones.

From the abstract:

In this work, we expose the cryptographic design and implementation of Android’s Hardware-Backed Keystore in Samsung’s Galaxy S8, S9, S10, S20, and S21 flagship devices. We reversed-engineered and provide a detailed description of the cryptographic design and code structure, and we unveil severe design flaws. We present an IV reuse attack on AES-GCM that allows an attacker to extract hardware-protected key material, and a downgrade attack that makes even the latest Samsung devices vulnerable to the IV reuse attack. We demonstrate working key extraction attacks on the latest devices. We also show the implications of our attacks on two higher-level cryptographic protocols between the TrustZone and a remote server: we demonstrate a working FIDO2 WebAuthn login bypass and a compromise of Google’s Secure Key Import.

Here are the details:

As we discussed in Section 3, the wrapping key used to encrypt the key blobs (HDK) is derived using a salt value computed by the Keymaster TA. In v15 and v20-s9 blobs, the salt is a deterministic function that depends only on the application ID and application data (and constant strings), which the Normal World client fully controls. This means that for a given application, all key blobs will be encrypted using the same key. As the blobs are encrypted in AES-GCM mode-of-operation, the security of the resulting encryption scheme depends on its IV values never being reused.

Gadzooks. That’s a really embarrassing mistake. GSM needs a new nonce for every encryption. Samsung took a secure cipher mode and implemented it insecurely.

    Samsung seemingly caught swapping components in its 970 Evo Plus SSDs

Recently, major SSD vendors Crucial and Western Digital have both been caught swapping out TLC NAND in their consumer SSDs for cheaper but much lower-performance, lower-endurance QLC NAND. Samsung appears to be joining them in the part-swapping corner of shame today, thanks to Chinese Youtuber 潮玩客, who documented a new version of the Samsung 970 Evo Plus using an inferior drive controller.

Although the consumer-facing model number of the drives did not change—it was a 970 Evo Plus last year, and it's still a 970 Evo Plus now—the manufacturer part number did. Unfortunately, the manufacturer part number isn't visible on the box the SSD comes in—as far as we've been able to determine, it's only shown on a small label on the drive itself.

Falling off the write cliff

We tested the 970 Evo Plus (alongside the 980, and the older 970 Pro) in March, clocking it at write speeds of 1,600+ MiB/sec on 1MiB workloads. Our benchmarking was done with he old version, part number MZVLB1T0HBLR. The newer version—part number MZVL21T0HBLU—is considerably slower. According to 潮玩客's test results, the newer version only manages 830MiB/sec—half the performance of the original.

    TSMC is considering a 3 nm foundry in Arizona

Reuters reports that TSMC—Taiwan Semiconductor Manufacturing Company, the chip foundry making advanced processors for Apple, AMD, and Qualcomm—is beefing up its plans to build factories in Arizona while turning away from an advanced plant in Europe.

Last year, TSMC announced that it would invest $10-$12 billion to build a new 5 nm capable foundry near Phoenix, Arizona. According to Reuters' sources, TSMC officials are considering trebling the company's investment by building a $25 billion second factory capable of building 3 nm chips. More tentative plans are in the works for 2 nm foundries as the Phoenix campus grows over the next 10-15 years as well.

US President Joe Biden called for $50 billion to subsidize US chip manufacturing facilities, and the US Senate may take action on the item this week. Strong domestic manufacturing capacity is seen as critical, since US chip firms such as Nvidia and Qualcomm rely on Asian manufacturing facilities. TSMC would be competing with Samsung and Intel to secure these Biden administration subsidies.

    Samsung will soon ship Micro LED TVs, but MiniLED still leads the lineup

    news.movim.eu / ArsTechnica · Tuesday, 2 March, 2021 - 21:32

It's that time of year when many TV manufacturers begin announcing prices for and shipping their annual product refreshes. We took a look at Sony's OLED lineup yesterday, but today we're turning our attention to Samsung, which just announced imminent availability (most models will start shipping this month) for its high-end Micro LED and MiniLED TV lineup.

We'll get to Micro LED in a minute, but let's start with the mainstream high-end, which are the MiniLED TVs. Samsung is giving these a proprietary "Neo QLED" label.

The top-end QN900A is the most tricked-out 8K option, with 65-inch ($5,000), 75-inch ($7,000), and 85-inch options ($9,000). One step down while keeping the 8K banner flying is the QN800A, offered in the same sizes but at $3,500, $4,700, and $6,500, respectively.

    Samsung says auto chip shortage could hit smartphones

Samsung says auto chip shortage could hit smartphones

Samsung Electronics said a global semiconductor shortage that has hit global carmakers could also disrupt orders for the memory chips used in smartphones, as manufacturers rushed to respond to the crisis.

The warning from the world’s biggest memory chipmaker comes as companies and governments grow concerned that constrained chip manufacturing capacity could derail countries’ economic recoveries from the coronavirus pandemic.

The rush by semiconductor foundries to meet demand for auto chips means many are now operating at full capacity, limiting their ability to take on new orders, which could in turn slow deliveries of chips designed for mobile devices.
