Universal Music has filed a copyright infringement lawsuit against artificial intelligence start-up Anthropic, as the world’s largest music group battles against chatbots that churn out its artists’ lyrics.

Universal and two other music companies allege that Anthropic scrapes their songs without permission and uses them to generate “identical or nearly identical copies of those lyrics” via Claude, its rival to ChatGPT.

When Claude is asked for lyrics to the song “I Will Survive” by Gloria Gaynor, for example, it responds with “a nearly word-for-word copy of those lyrics,” Universal, Concord, and ABKCO said in a filing with a US court in Nashville, Tennessee.

Tesla drivers will soon have a new place to fast-charge their electric vehicles. Today, the charging network ChargePoint announced it will have Tesla-style North American Charging Standard support for both its AC and DC chargers over the next few weeks. And in November, it will start shipping NACS cable upgrade kits for existing DC fast chargers, which will allow Tesla EVs to charge at those ChargePoint DC fast chargers.

"We've already said we're already taking preorders on the home charger, and then over the next few weeks, we'll start shipping the fast-charge cables to preorder customers that have our fast chargers, and you can already order a new fast charger with NACS cables on," said Pasquale Romano, ChargePoint's CEO.

"We think the most important difference is we do not make our customers decide by parking space whether the cable is NACS or CCS. I think that's a mess and no one should do that. No one should have a dedicated parking space because you'll never get the ratio right, and it will change over time. So every solution that we have is going to enable both connector types per parking space," he told Ars.

In 2015, researchers reported a surprising discovery that stoked industry-wide security concerns—an attack called RowHammer that could corrupt, modify, or steal sensitive data when a simple user-level application repeatedly accessed certain regions of DDR memory chips. In the coming years, memory chipmakers scrambled to develop defenses that prevented the attack, mainly by limiting the number of times programs could open and close the targeted chip regions in a given time.

Recently, researchers devised a new method for creating the same types of RowHammer-induced bitflips even on the newest generation of chips, known as DDR4, that have the RowHammer mitigations built into them. Known as RowPress, the new attack works not by “hammering” carefully selected regions repeatedly, but instead by leaving them open for longer periods than normal. Bitflips refer to the phenomenon of bits represented as ones change to zeros and vice versa.

Further amplifying the vulnerability of DDR4 chips to read-disturbance attacks—the generic term for inducing bitflips through abnormal accesses to memory chips—RowPress bitflips can be enhanced by combining them with RowHammer accesses. Curiously, raising the temperature of the chip also intensifies the effect.
