The North Korean threat actor known as Lazarus Group has been attributed to the zero-day exploitation of a newly patched security flaw impacting Microsoft Windows to deliver a never-before-seen backdoor targeting defense and aerospace companies across France, Germany, Brazil, and India. The activity, per Check Point Research, is part of Operation Dream Job , a long-running cyber espionage and social engineering campaign orchestrated by Pyongyang-backed hackers to target professionals worldwide with fake-but-compelling job offers at firms like Lockheed Martin and Enveil to steal sensitive data and install malware by approaching them on platforms like LinkedIn, pretending to be recruiters in an attempt to build trust. The attacks have been found to exploit CVE-2026-68820 (CVSS score: 7.0), a privilege escalation flaw affecting Windows Ancillary Function Driver for WinSock ("AFD.sys") that was patched by Microsoft as part of its Patch Tuesday updates for August 2026.

A newly disclosed flaw in the way OpenAI, Anthropic, and Google carried hidden AI reasoning between API calls let researchers recover internal reasoning and secrets from session logs, including API keys and passwords. The weakness affected encrypted reasoning objects used by the providers' reasoning APIs, where a block created in one session could be replayed into another and, during testing, even handed to a weaker model in the same provider family to make it reveal the hidden content. The team behind the paper  Stealing Reasoning Traces from Proprietary LLM APIs  demonstrated four abuse paths: stealing proprietary reasoning for  model distillation , extracting private data from other users' published traces, recovering harmful content concealed behind a safe visible answer, and hiding prompt injections inside opaque reasoning blocks. Across 6,708 public agent trajectories, the team decoded 315,320 thinking blocks. After excluding benchmark sources, it counted 704...

Adobe has shipped updates to address multiple critical security vulnerabilities impacting ColdFusion, Commerce, and Campaign Classic that, if successfully exploited, could result in arbitrary code execution and privilege escalation. The most severe of the flaws are listed below - CVE-2026-48362 (CVSS score: 10.0) - An operating system command injection vulnerability in ColdFusion that could lead to arbitrary code execution (Fixed in 2025.0.12 and 2023.0.23) CVE-2026-48273 (CVSS score: 9.9) - An eval injection vulnerability in ColdFusion that could lead to arbitrary code execution (Fixed in 2025.0.12 and 2023.0.23) CVE-2026-71384 (CVSS score: 9.6) - An incorrect authorization vulnerability in ColdFusion that could lead to an application denial-of-service (Fixed in 2025.0.12 and 2023.0.23) CVE-2026-71362 (CVSS score: 9.1) - An incorrect authorization vulnerability in Commerce that could lead to privilege escalation CVE-2026-71398 (CVSS score: 10.0) - An incorrec...

Threat actors have begun to actively exploit a recently patched critical security flaw in Broadcom VMware vCenter, according to new findings from QUIRSO. The vulnerability in question is CVE-2026-59310 (CVSS score: 9.8), a directory-traversal vulnerability in the VMware vCenter server that a malicious actor with network access can exploit to execute arbitrary code. Patches for the flaw were released by Broadcom late last month. The German cybersecurity company said it discovered the activity following an incident response engagement. The attack chain is said to have exhibited path traversal activity consistent with the flaw, followed by the deployment of a malicious cron job to establish persistence on the host using reverse_ssh, an open-source tool used for setting up SSH connections to threat actor-controlled infrastructure. Compromised systems identified by QUIRSO were found to first establish contact with the attacker's domains on August 3, five days after Broadcom pub...

Two malicious LiteLLM releases sat on PyPI for about 40 minutes in March carrying credential-stealing code capable of harvesting cloud keys, SSH keys, Kubernetes tokens, database passwords, and other secrets from systems that installed them. Threat intelligence firm CloudSEK now says a dataset it obtained, built from roughly 434,000 files the attackers captured, maps potential exposure to more than 2,500 organizations. Those totals are not a victim count. CloudSEK told The Hacker News the material came from confidential intelligence sources and consists of captured loot and log files it assessed as belonging to the campaign, not data gathered from the organizations it names. The files were taken, in other words. CloudSEK has published the dataset as  a public lookup , searchable by name or domain and filterable by confidence. Each row gives an organization's name and domain, a count of secrets exposed, a count of runs, and a label reading High or Medium. What a high-co...
