Meta is facing a class-action lawsuit from authors over the use of pirated books for training its Llama language model, arguing that the distribution of these books via BitTorrent constitutes fair use. The company used shadow libraries like Anna's Archive to gather text, and a California court has partially ruled that using pirated books for training large language models falls under fair use, although the issue of copyright infringement related to downloading and distribution via BitTorrent remains unresolved. The plaintiffs claim Meta has not previously indicated a fair use defense regarding file-sharing, while Meta asserts that authors have not shown evidence of their works being reproduced by the Llama model. The judge will ultimately decide on the admissibility of Meta's defense.

A cyber operation is targeting users of Huorong Security antivirus software through a typosquatted domain, huoronga[.]com, which mimics the legitimate site huorong.cn. Users who mistakenly visit the counterfeit site may download a file named BR火绒445[.]zip, which contains a trojanized installer that leads to the installation of ValleyRAT, a remote access trojan. The malware employs various techniques to evade detection, including using an intermediary domain for downloads, creating Windows Defender exclusions, and establishing a scheduled task for persistence. The backdoor facilitates activities such as keylogging and credential access while disguising its operations within legitimate processes like rundll32.exe. Attribution points to the Silver Fox APT group, and there has been a significant increase in ValleyRAT samples documented in recent months. Security measures include ensuring software downloads are from the official site and monitoring for specific malicious activities.
