ChainCatcher news, according to Coindesk, a new type of Linux malware is globally attacking unprotected Docker infrastructures, turning exposed servers into a decentralized network for mining the privacy coin Dero. The malware attacks exposed Docker APIs through port 2375, deploying two Golang-based implants, one disguised as legitimate web server software nginx, and another program named cloud for mining. Infected nodes autonomously scan the internet for new targets and deploy infected containers without the need for a central control server.As of early May, over 520 Docker APIs worldwide were publicly exposed through port 2375, all of which are potential attack targets. Research shows that the wallets and node infrastructure used in this attack are the same as those used in attacks on Kubernetes clusters in 2023 and 2024.

ChainCatcher news, a group of Coinbase users from Illinois has filed a class-action lawsuit against the cryptocurrency exchange, accusing it of violating the state's Biometric Information Privacy Act (BIPA) with its identity checks.Plaintiffs Scott Bernstein, Gina Greeder, and James Lonergan claim in a complaint submitted to federal court on May 13 that Coinbase "massively collects" facial recognition information to meet its "Know Your Customer" (KYC) requirements, violating BIPA as users were not notified.The group claims that Coinbase did not provide written notice to users regarding the collection, storage, or sharing of their biometric data, as well as the purpose of data use and retention schedule."Coinbase has not publicly provided a retention schedule or guidelines for the permanent destruction of the plaintiffs' biometric identifiers, which violates BIPA," they allege.The complaint states that Coinbase requires users to verify their identity by uploading government-issued photo IDs and selfies, which are then sent to third-party facial recognition software for scanning and extraction of facial geometric data. This process captures biometric identifiers without obtaining informed written consent from users, the lawsuit claims, which violates BIPA.

ChainCatcher news, according to Bitcoin.com, Brazil's central bank digital currency (CBDC) pilot project Drex is facing difficulties as the resources allocated to the project have decreased, slowing down its progress and hindering development.The two largest companies involved in designing the project's privacy solutions—Microsoft and Ernst & Young—have recently reduced their manpower dedicated to these efforts. This deadlock is related to the central bank's recent actions, as it ended the second phase of the Drex pilot without approving any projects submitted by participants. The privacy proposals that needed to ensure transaction confidentiality while allowing regulatory review did not meet the central bank's requirements in this regard, leaving the Drex project currently stalled.Ernst & Young, which is responsible for the Starlight privacy project, has lost three personnel involved in the development of this solution. Meanwhile, after investing significant resources last year, Microsoft has also reduced its involvement in the ZKP Nova privacy proposal. However, Microsoft's partner Hamsa will continue to test and support ZKP Nova.Central bank executive secretary Rogerio Lucca recently pointed out that the team behind Drex is still researching the project's future. He stated, "Based on the ongoing test results, the technical team is currently discussing possible future steps for the project." However, he did not disclose the test results.
