LangSmith Vulnerability Risks Exposure of OpenAI Keys and User Data through Malicious Agents

June 17, 2025
Category: Vulnerability / LLM Security

Cybersecurity experts have revealed a recently fixed security flaw in the LangChain’s LangSmith platform that could be exploited to obtain sensitive information, including API keys and user prompts. The vulnerability, assigned a CVSS score of 8.8 out of 10.0, is codenamed AgentSmith by Noma Security. LangSmith serves as an observability and evaluation tool for developing, testing, and monitoring large language model (LLM) applications, including those created using LangChain. Additionally, it features a LangChain Hub that acts as a repository for publicly available prompts, agents, and models.

“This newly discovered vulnerability targeted unsuspecting users who adopted agents containing pre-configured malicious proxy servers uploaded to the ‘Prompt Hub,'” noted researchers Sasi Levi and Gal Moyal in a report shared with The Hacker News. “Once adopted, the malicious proxy discreetly intercepted all user communications…”

TA829 and UNK_GreenSec Collaborate on Strategies and Infrastructure in Ongoing Malware Campaigns

July 01, 2025
Cyber Espionage / Vulnerability

Cybersecurity experts have identified striking tactical parallels between the threat actors behind the RomCom RAT and a group observed deploying a loader named TransferLoader. Enterprise security firm Proofpoint is tracking this activity back to a group recognized as UNK_GreenSec, alongside the RomCom RAT actors, referred to as TA829. This group is also known by multiple aliases, including CIGAR, Nebulous Mantis, Storm-0978, Tropical Scorpius, UAC-0180, UAT-5647, UNC2596, and Void Rabisu. According to Proofpoint’s findings, UNK_GreenSec emerged during their investigation of TA829, with notable similarities in infrastructure, delivery tactics, landing pages, and email lure themes. TA829 stands out in the threat landscape for its capacity to engage in both espionage and financially motivated attacks. This hybrid group, aligned with Russia, has been linked to the exploitation of zero-day vulnerabilities in Mozilla software.

Qilin Ransomware Introduces “Call Lawyer” Feature to Increase Pressure on Victims for Higher Ransoms

June 20, 2025
Ransomware / Cybercrime

The operators of the Qilin ransomware-as-a-service (RaaS) platform have unveiled a new “Call Lawyer” feature intended to pressure victims into paying larger ransoms. This strategic move comes as the group ramps up its activities to capitalize on the decline of competing cybercriminals. According to Israeli cybersecurity firm Cybereason, this feature is integrated into the affiliate panel, allowing affiliates to present legal counsel offers to victims.

This development marks a resurgence in Qilin’s operations at a time when other once-dominant ransomware factions, such as LockBit, Black Cat, and others, have faced sudden shutdowns and operational issues. Active since October 2022 and also known as Gold Feather and Water Galura, Qilin has emerged as a significant player in the ransomware landscape.

Data from dark web leak sites reveals that Qilin was responsible for 72 attacks in April 2025 and an estimated 55 in May, placing it behind only Safepay (72) and Luna Moth (67) in activity.

Critical Flaw in Anthropic’s MCP Poses Remote Exploitation Risk for Developer Systems

July 01, 2025
Vulnerability / AI Security

Cybersecurity experts have identified a severe security flaw in Anthropic’s Model Context Protocol (MCP) Inspector project, potentially enabling remote code execution (RCE) and granting attackers total access to affected systems. Identified as CVE-2025-49596, this vulnerability boasts a CVSS score of 9.4 out of 10, indicating a critical risk level. “This represents one of the first significant RCE vulnerabilities within Anthropic’s MCP framework, opening the door to a new wave of browser-based attacks targeting AI development tools,” stated Avi Lumelsky from Oligo Security in a recent report. “With the ability to execute code on a developer’s machine, attackers can compromise sensitive data, install malware, and navigate through networks—posing serious threats to AI teams, open-source initiatives, and enterprises utilizing MCP.” Introduced by Anthropic in November 2024, MCP is an open protocol aimed at standardizing large language model (LLM) applications…

Threat Intelligence / Malware

The Russian threat actor RomCom has been linked to a surge of cyberattacks against Ukrainian government agencies and undisclosed Polish entities since late 2023. These intrusions utilize a new variant of the RomCom RAT, referred to as SingleCamper (also known as SnipBot or RomCom 5.0), according to Cisco Talos, which is monitoring this activity cluster under the designation UAT-5647. “This version is loaded directly from the registry into memory and communicates with its loader via a loopback address,” explained security researchers Dmytro Korzhevin, Asheer Malhotra, Vanja Svajcer, and Vitor Ventura. RomCom, also tracked as Storm-0978, Tropical Scorpius, UAC-0180, UNC2596, and Void Rabisu, has engaged in multi-faceted operations including ransomware, extortion, and targeted credential harvesting since its emergence in 2022. Recent assessments indicate that the frequency of their attacks has ramped up in recent months with the goal of establishing long-term persistent access.
