Hundreds of open source Large Language Model (LLM) builder servers and dozens of vector databases leak sensitive data to the web. There is a rush among companies to implement Artificial Intelligence (AI) into their business workflows, but not enough attention is paid to securing these tools and the information they handle. Naphtali Deutsch, a researcher at Legit Security, scanned the web for two potentially vulnerable open source AI services: vector databases, which store data for AI tools, and LLM application builders, such as Flowise.

"Peach Sandstorm," an Iran-backed hacking group, has created a new custom multi-stage backdoor to infiltrate targets during cyber espionage operations. Microsoft Threat Intelligence named the new malware "Tickler," which has been used in attacks against targets in the satellite, communications equipment, oil and gas as well as federal and state government sectors. Microsoft Threat Intelligence discovered two samples of the Tickler malware launched by Peach Sandstorm in compromised environments between April and July 2024.

According to Cisco Talos, "BlackByte" ransomware attackers have exploited a recently patched VMware ESXi hypervisor flaw while also abusing different vulnerable drivers to disable security. The group is changing tactics by exploiting a VMware ESXi authentication bypass vulnerability, which other ransomware groups have also weaponized. This article continues to discuss the BlackByte ransomware group's exploitation of an authentication bypass vulnerability in VMware ESXi.
