Slashdot: Lawyer Cited 6 Fake Cases Made Up By ChatGPT; Judge Calls It 'Unprecedented'

Lawyer Cited 6 Fake Cases Made Up By ChatGPT; Judge Calls It 'Unprecedented'
Published on May 31, 2023 at 03:30AM
An anonymous reader quotes a report from Ars Technica: A lawyer is in trouble after admitting he used ChatGPT to help write court filings that cited six nonexistent cases invented by the artificial intelligence tool. Lawyer Steven Schwartz of the firm Levidow, Levidow, & Oberman "greatly regrets having utilized generative artificial intelligence to supplement the legal research performed herein and will never do so in the future without absolute verification of its authenticity," Schwartz wrote in an affidavit (PDF) on May 24 regarding the bogus citations previously submitted in US District Court for the Southern District of New York. Schwartz wrote that "the use of generative artificial intelligence has evolved within law rms" and that he "consulted the artificial intelligence website ChatGPT in order to supplement the legal research performed." The "citations and opinions in question were provided by ChatGPT which also provided its legal source and assured the reliability of its content," he wrote. Schwartz admitted that he "relied on the legal opinions provided to him by a source that has revealed itself to be unreliable," and stated that it is his fault for not confirming the sources provided by ChatGPT. Schwartz didn't previously consider the possibility that an artificial intelligence tool like ChatGPT could provide false information, even though AI chatbot mistakes have been extensively reported by non-artificial intelligence such as the human journalists employed by reputable news organizations. The lawyer's affidavit said he had "never utilized ChatGPT as a source for conducting legal research prior to this occurrence and therefore was unaware of the possibility that its content could be false." Federal Judge Kevin Castel is considering punishments for Schwartz and his associates. In an order on Friday, Castel scheduled a June 8 hearing at which Schwartz, fellow attorney Peter LoDuca, and the law firm must show cause for why they should not be sanctioned. "The Court is presented with an unprecedented circumstance," Castel wrote in a previous order on May 4. "A submission filed by plaintiff's counsel in opposition to a motion to dismiss is replete with citations to non-existent cases... Six of the submitted cases appear to be bogus judicial decisions with bogus quotes and bogus internal citations." [...] In the order issued on Friday last week, Castel said that Schwartz may be sanctioned for "the citation of non-existent cases to the Court," "the submission to the Court of copies of non-existent judicial opinions," and "the use of a false and fraudulent notarization." Schwartz may also be referred to an attorney grievance committee for additional punishment. Castel wrote that LoDuca may be sanctioned "for the use of a false and fraudulent notarization in his affidavit filed on April 25, 2023." The law firm could be sanctioned for "the citation of non-existent cases to the Court," "the submission to the Court of copies of non-existent judicial opinions annexed to the Affidavit filed on April 25, 2023," and "the use of a false and fraudulent notarization in the affidavit filed on April 25, 2023."

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features. Read more of this story at Slashdot.

Slashdot: Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications

Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications Published on December 16, 2024 at 01:04AM Launched in 2013, itch.io lets users host and sell indie video games online — now offering more than 200,000 — as well as other digital content like music and comics. But then someone uploaded a page based on a major videogame title, according to Game Rant. And somehow this provoked a series of overreactions and missteps that eventually knocked all of itch.io offline for several hours... The page was about the first release from game developer 10:10 — their game Funko Fusion, which features characters in the style of Funko's long-running pop-culture bobbleheads. As a major brand, Funko monitors the web with a "brand protection" partner (named BrandShield). Interestingly, BrandShield's SaaS product "leverages AI-driven online brand protection," according to their site, to "detect...
