Qilin Ransomware Attackers Exploit PAN-OS Authentication Bypass for Initial Access

Qilin Ransomware Attackers Exploit PAN-OS Authentication Bypass for Initial Access

Jul 21, 2026 Vulnerability / Network Security
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 Patches Critical SNMP Command Injection and Four XSS Vulnerabilities

Zimbra Patches Critical SNMP Command Injection and Four XSS Vulnerabilities

Jul 21, 2026 Email Security / Vulnerability
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...
Open-Source Android AI Agents Could Let Invisible Screen Text Run Code on Host PCs

Open-Source Android AI Agents Could Let Invisible Screen Text Run Code on Host PCs

Jul 21, 2026 Vulnerability / AI Security
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...

N-day is Becoming N-Hour. Patching Faster Won't Save You.

Jul 21, 2026 Artificial Intelligence / Browser Security
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...
New Bit2Watt Attack Could Let Cloud Tenants Disrupt Power Grids Without an Exploit

New Bit2Watt Attack Could Let Cloud Tenants Disrupt Power Grids Without an Exploit

Jul 21, 2026 Critical Infrastructure / Cloud Security
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...

WordPress wp2shell Exploitation Grows as Public Exploit Fuels Mass Scanning

WordPress wp2shell Exploitation Grows as Public Exploit Fuels Mass Scanning

Jul 21, 2026 Vulnerability / Cyber Attacks
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...
New ENCFORGE Ransomware Targets AI Model Files in Langflow RCE Attack

New ENCFORGE Ransomware Targets AI Model Files in Langflow RCE Attack

Jul 21, 2026 Threat Intelligence / Vulnerability
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...
Critical ServiceNow AI Platform Flaw Exploited for Unauthenticated Code Execution

Critical ServiceNow AI Platform Flaw Exploited for Unauthenticated Code Execution

Jul 21, 2026 Vulnerability / Artificial Intelligence
Threat actors are now exploiting a recently disclosed critical security flaw impacting ServiceNow AI Platform, according to Defused Cyber . In a post shared on X, the threat intelligence firm said it's observing in-the-wild exploitation of CVE-2026-6875 (CVSS score: 9.5), a sandbox escape vulnerability that could allow an unauthenticated user to run arbitrary code. Patches for the flaw were released by ServiceNow throughout June in the following versions - Brazil EA and Brazil GA Australia Patch 2 Zurich Patch 7b and Zurich Patch 9 Yokohama Patch 12 Hot Fix 1b and Yokohama Patch 13 Searchlight Cyber, which disclosed additional technical specifics, said it reported the issue on April 1, 2026, adding it allows a complete compromise of the ServiceNow instance as well as all connected proxy servers. Besides rolling out a fix, ServiceNow is "enhancing instance security by severely restricting the type of code that can run in sandbox contexts," securit...
FakeGit Campaign Uses 7,600 GitHub Repositories to Spread SmartLoader Malware

FakeGit Campaign Uses 7,600 GitHub Repositories to Spread SmartLoader Malware

Jul 20, 2026 Malware / Artificial Intelligence
Cybersecurity researchers have discovered nearly 7,600 malicious GitHub repositories, out of which more than 800 pose as artificial intelligence (AI) skills or Model Context Protocol (MCP) servers to deliver a malware family known as SmartLoader as part of an ongoing campaign codenamed FakeGit . "FakeGit uses copied projects, lookalike developer profiles, convincing READMEs, and malicious ZIP files to deliver SmartLoader malware," Oleg Zaytsev, lead security researcher at Island, said in a report shared with The Hacker News. The end goal of these attacks is to leverage the access afforded by SmartLoader to establish persistence and push secondary payloads, such as StealC, an information stealer capable of harvesting a wide range of data from compromised systems. It's worth mentioning here that the use of trojanized MCP servers to distribute SmartLoader and StealC was flagged earlier this year by Straiker AI and subsequently by Derp.ca . But a concerning aspect ...
Exposed Server Reveals AI-Assisted Phishing Toolkit Behind WebDAV Malware Campaign

Exposed Server Reveals AI-Assisted Phishing Toolkit Behind WebDAV Malware Campaign

Jul 20, 2026 Malware / Vulnerability
A malware operator left its delivery server wide open, and Rapid7 pulled down the whole toolkit: 1,048 files spanning lure templates, filename-spoofing tests, execution experiments, droppers, builder notes, and two campaign chains. One was already live against Windows users in Mexico, delivering an infostealer through a fake government ID-lookup site over WebDAV. What makes it more than a payload dump: it caught the operation mid-build. Testing notes, failed experiments, documentation, and live delivery logs sat in one place, the kind of complete development trail defenders rarely see. Rapid7 reads the artifacts, down to a hardcoded path pointing at an open-source AI coding tool, as an operator using generative AI to produce, test, and document phishing delivery at speed. The most developed test set focused on CVE-2025-33053 (CVSS 8.8, now in CISA's KEV catalog ), the WebDAV working-directory hijack Check Point documented last year in its Stealth Falcon reporting.

HollowGraph Malware Hides C2 and Stolen Files in Microsoft 365 Events Dated 2050

HollowGraph Malware Hides C2 and Stolen Files in Microsoft 365 Events Dated 2050

Jul 20, 2026 Cyber Espionage / SaaS Security
A newly discovered espionage implant has been using a hijacked Microsoft 365 calendar as its command channel, planting operator instructions and smuggling out stolen files as attachments on calendar events dated to the year 2050. Group-IB , which named the malware HollowGraph , says the approach moves tasking and stolen data through legitimate Microsoft Graph API traffic, so the activity looks like ordinary Microsoft 365 chatter and network controls keyed to attacker-owned destinations have nothing to flag. The implant is a .NET DLL that supports just two commands, get and send , and it never reaches out to an attacker-owned server for payloads. Instead, it treats the compromised mailbox's calendar as a two-way dead drop. To pull tasking, it queries the calendar for an event the operator has planted, buried at 2050-05-13 , so the mailbox owner is unlikely to ever scroll to it, and reads its instructions from an attached file. To exfiltrate, it does the reverse: encrypts th...

Jul 20, 2026 Cybersecurity / Hacking
A single request should not be able to do this much. But this week, small inputs led to code execution, memory loss, stolen keys, and disabled security tools. The paths were often simple: exposed systems, weak checks, old drivers, fake prompts, and public code used for malware delivery. Some bugs were new. Others were already being used before defenders had time to patch. Here is the full recap of what broke, what was exploited, and what needs attention now. ⚡ Threat of the Week New wp2shell WordPress Core Flaw Lets Unauthenticated Attackers Run Code - Searchlight Cyber disclosed a pre-authenticated remote code execution vulnerability in WordPress Core that can be exploited anonymously on a standard WordPress installation, without requiring any plugins or other special conditions.

Russian Intelligence Hacks IP Cameras to Spy on Military Logistics Across NATO States and Ukraine

Russian Intelligence Hacks IP Cameras to Spy on Military Logistics Across NATO States and Ukraine

Jul 20, 2026 IoT Security / Cyber Espionage
At least one Russian intelligence service is systematically hijacking internet-connected security cameras across Europe and Ukraine, using the feeds to watch military transport routes, weapons shipments bound for Kyiv , and the locations of Ukrainian troops. That is the finding of a cybersecurity advisory published July 10 by the AIVD and MIVD, the Netherlands' civilian and military intelligence services, which describe the operation as ongoing. In Ukraine, the surveillance has not stayed passive. Camera access there has been "used in attempts to neutralise Ukrainian military personnel" and destroy their equipment, the services say, turning an exposed roadside or business camera into a targeting aid. Across EU and NATO states, the services add, the same camera access is also collecting military intelligence that has nothing to do with the war. Getting in is rarely the hard part. The operators scan the internet for exposed devices, fingerprint IP cameras by bran...
Mythos Didn't Break Your Security Program. Your Exposure Window Could.

Mythos Didn't Break Your Security Program. Your Exposure Window Could.

Jul 20, 2026 Security Operations / Exposure Management
The industry spent the initial months after Anthropic's April 7 Mythos reveal focused on volume . How many new CVEs would Mythos add to an already overloaded pipeline? How quickly would the flood of AI-driven discovery overwhelm triage capabilities? How long would it take adversaries to weaponize Mythos findings at scale? Those questions were and remain valid. Yet they all stop short of addressing the single metric that determines whether any of those vulnerabilities actually lead to a breach: the exposure window. The exposure window - the gap between the moment a vulnerability becomes exploitable and the moment your team fixes it - is the time an attacker has to do actual damage. That window is currently open far too wide. In 2025, the average eCrime breakout time dropped to 29 minutes . Even PCI DSS - the strictest compliance framework in the industry - allows 30 days to remediate a critical vulnerability. That's a 1,000-to-1 gap between how fast attackers move and how f...
