Threat actors have been observed exploiting a now-patched high-severity Palo Alto Networks PAN-OS vulnerability as an entry point to deploy Qilin (aka Agenda) ransomware on victim environments. Arctic Wolf Labs said it investigated multiple intrusions in June 2026 that began with the exploitation of CVE-2026-0257 (CVSS score: 7.8), an authentication bypass flaw affecting the portal and gateway components of PAN-OS software. Successful exploitation of the flaw allows unauthenticated remote attackers to sidestep authentication and establish VPN sessions without valid credentials when authentication override cookies are enabled with specific certificate configurations. "Post-exploitation tradecraft varied across intrusions, from rapid encryption-only operations to full double-extortion, possibly suggesting multiple affiliates operating under the Qilin ransomware-as-a-service (RaaS) umbrella," the cybersecurity company said .

Zimbra has rolled out fixes to address multiple critical security issues, including a command injection flaw in the Simple Network Management Protocol (SNMP) monitoring component. As many as nine security vulnerabilities have been patched in Zimbra 10.1.20 . Topping the list is a command injection vulnerability in the SNMP monitoring component when SNMP notifications are enabled. Also patched are four cross-site scripting (XSS) flaws in the Classic Web Client - A stored cross-site scripting (XSS) vulnerability that could allow malicious attachment filenames to execute script under specific conditions. An XSS vulnerability where crafted fields could execute a malicious script under specific conditions. An XSS vulnerability where a crafted field could execute a malicious script when rendered. An XSS vulnerability where crafted attachments could execute a malicious script when rendered. Separately, fixes have been released for a mail forwarding restriction bypass (CV...

An Android app that can draw over other windows and write to shared storage can slip instructions to the AI agent driving that phone, in text no human eye will ever see. Two more steps, and the same app is running commands on the PC driving the agent. Researchers demonstrated that chain, plus six other attacks, against five open-source mobile agent frameworks: AppAgent, AppAgentX, Mobile-Agent-v3, Open-AutoGLM, and MobA. Everyone fell to at least six of the seven. The paper went up on arXiv on July 1 and was revised on July 14. The authors are at Simon Fraser University, the Chinese University of Hong Kong, Shandong University, and the Xingtu Lab at Chinese security firm QAX. Nothing here has a CVE, and first author Zidong Zhang told The Hacker News the team has no evidence of the techniques being used outside a controlled setting. The Hacker News checked all five frameworks and found the screenshot paths, the shell call, and the broadcast fallback that the paper describes st...

Every patch is a confession. The moment a vendor ships a security fix, the diff between the old code and the new code tells anyone watching exactly what was broken and where. Turn that diff back into a working exploit, and you can hit every system that hasn't updated yet. This is N-day exploitation, and it's always been a race: the vendor patches, the clock starts, and defenders try to deploy before an attacker finishes reverse-engineering the fix. For the last thirty-odd years, defenders usually won that race. Reverse-engineering a patch into a reliable exploit was slow, specialized work - usually requiring weeks of expert-level effort. Historically, the gap between a patch and a working public exploit spanned weeks, often months. The traditional playbook assumed you had at least a few weeks. You don't anymore. Not even close. Reverse-engineering a patch used to take weeks. Mythos does it in an hour. Anthropic's red team measured exactly that. Given not...

A cloud tenant using nothing but ordinary GPU access can push a data center's power draw up and down fast enough to threaten the grid it runs on, with no exploit and no break-in. That is the claim behind Bit2Watt , described by three Zhejiang University researchers in a paper accepted to CHES 2026 , the IACR's hardware-security conference, and the evidence splits in two: they measured the power modulation on real GPUs and simulated the grid destabilization it could cause. The technique inverts the usual grid-attack model: no compromised sensors, no malware on control systems, no stolen operator credentials, just a workload built to misbehave on purpose. It works because a GPU's power draw follows whatever it is computing. Saturate the tensor cores and current spikes; drop to idle, and it collapses. Toggle between those states on a schedule and you get a controllable power oscillation at the wall socket. The authors frame it as a blunt question: can "purely com...

Attackers have begun to exploit two critical vulnerabilities in WordPress that, when combined together, enable unauthenticated remote code execution (RCE) and complete compromise of vulnerable websites. The two security flaws, tracked as CVE-2026-63030 and CVE-2026-60137 , have been codenamed wp2shell . "By the early hours of Saturday morning (UTC), successful exploitation was already well underway, initially using public exploit code to exfiltrate hashed credentials, with remote code execution following once additional details were made public," Jake Knott, principal security researcher at watchTowr, told The Hacker News in a statement. "From our vantage point across a global client base, we are seeing widespread impact of this vulnerability across organizations of every size and every vertical." Telemetry data captured by KEVIntel shows that 13 unique IP addresses from Switzerland, Germany, the U.K., Indonesia, Lithuania, the Netherlands, and Singapore h...

Researchers at Sysdig have linked a second attack on the same Langflow server to JADEPUFFER , the AI-agent-driven operator it first documented earlier this month. The same operator has now been spotted deploying ENCFORGE , a new compiled Go ransomware designed to encrypt model weights, vector indexes, training datasets, and other AI infrastructure files across the host filesystem. The entry point did not change. Langflow versions before 1.3.0 expose the /api/v1/validate/code endpoint without authentication, allowing any remote attacker to execute arbitrary Python on the server. The flaw, CVE-2025-3248 , carries a CVSS score of 9.8 and has been in CISA's Known Exploited Vulnerabilities catalog since May 5, 2025. As The Hacker News reported earlier this month, the prior operation used throwaway Python code and MySQL's AES_ENCRYPT() function to encrypt and destroy data in Nacos (Alibaba's configuration server) and production databases. The new ENCFORGE payload re...
