Daily Cybersecurity Roundup, June 03, 2025

When your tools start spying on you, it’s time to check for hidden tricks — and that’s exactly what researchers found. A supply chain attack was discovered involving two malicious Ruby gems stealthily designed to steal Telegram bot tokens, messages, and files. In parallel, threat actor JINX-0132 is orchestrating a widespread cryptojacking campaign by exploiting misconfigurations in popular DevOps platforms to deploy XMRig miners on compromised infrastructure. Adding to global concerns, the Dutch Minister has issued a stark warning about the rising wave of Chinese state-sponsored cyber espionage, particularly aimed at the Netherlands’ critical infrastructure. Read further for more cybersecurity news from the last 24 hours.
