⚡ Weekly Recap: Chrome 0-Day, UniFi Exploits, macOS Stealers, VPN Flaw and More

Jun 15, 2026 Cybersecurity / Hacking
Stuff broke again. Not in a movie way. An old tool was left exposed. An abandoned package was abused. A deprecated feature was still running in prod. This week is the same lesson in a new form: phishing kits are easier to rent, AI names are useful bait, old login paths still fail, and forgotten software keeps becoming someone else's entry point. Scroll through the full Monday Cybersecurity Recap below for the news, tools, webinars, and fixes worth your time this week. ⚡ Threat of the Week Google Patches Actively Exploited Chrome 0-Day - Google released security updates to address 74 vulnerabilities, including one that has come under active exploitation in the wild.

The Onboarding Password Mistake That Creates Unnecessary Risk

The Onboarding Password Mistake That Creates Unnecessary Risk

Jun 15, 2026 Password Security / Critical Infrastructure
Employee onboarding is a busy time for IT teams. New starters need devices, accounts, access permissions, and passwords, all delivered within a tight timeframe. That usually means sharing a temporary "first-day" password so employees can access systems for the first time. The issue is that these passwords don't always stay temporary. They may be sent over email or SMS, reused across accounts, or never changed at all, creating unnecessary risk during the onboarding process. For attackers, weak or poorly managed onboarding credentials can provide an easy route into corporate systems. To make the onboarding process more secure without slowing new employees down, it's important to understand why typical password-sharing methods introduce risk. When convenience overrides security The most common approach to sharing initial credentials with new employees is to send them in plain text over email or SMS. It's quick and convenient, especially during busy onboardin...

Popular WordPress Plugin Scripts Tampered to Plant Hidden Backdoors on Sites

Popular WordPress Plugin Scripts Tampered to Plant Hidden Backdoors on Sites

Jun 15, 2026 Web Security / Supply Chain Attack
An attacker tampered with trusted JavaScript files used by WordPress sites running PushEngage , OptinMonster , and TrustPulse , turning those files into a way to break into the sites. When a site administrator was logged in as the file loaded, the code created an admin account under the attacker's control and installed a hidden plugin that opened a way back in. Ordinary visitors did not trigger it. Any site that was hit should be treated as compromised. All three plugins are run by one company, Awesome Motive, which had not commented on the two larger plugins as of June 15. Security firm Sansec disclosed the wider campaign on June 13, finding the same malicious code in JavaScript served for all three plugins. PushEngage followed a day later with its own incident notice , confirming an attacker had served tampered copies of its script and that sites loading them could be taken over. PushEngage, acquired by Awesome Motive years ago, is so far the only one of the three to ...
Sniper Dz Scams Target MENA Users via Fake Facebook Offers and Browser Alerts

Sniper Dz Scams Target MENA Users via Fake Facebook Offers and Browser Alerts

Jun 15, 2026 Social Engineering / Browser Security
Cybersecurity researchers have disclosed details of fraudulent activity targeting users across the Middle East and North Africa by employing various fraudulent Facebook accounts impersonating politicians, public figures, and trusted organizations. "These accounts promoted fake offers, including free mobile internet packages, financial compensation, and government subsidy programs," Group-IB analysts Anna Yurtaeva and Viacheslav Shevchenko said . "Victims were encouraged to click embedded links to claim the advertised benefits, but were instead redirected through a chain of intermediary websites that ultimately led to phishing and traffic monetization infrastructure." The Singapore-headquartered cybersecurity company has these campaigns to Sniper Dz , a turnkey phishing-as-a-service (PhaaS) platform that was taken down last month in an INTERPOL-led operation. The findings indicate that the platform goes beyond facilitating credential theft, generating illicit ...

Critical Splunk Enterprise Flaw Lets Attackers Run Code Without Authentication

Jun 13, 2026 Vulnerability / Enterprise Software
Splunk has released security updates to address a critical security flaw in Splunk Enterprise that could be exploited to conduct unauthenticated file operations and even remote code execution. The vulnerability, tracked as CVE-2026-20253 , is rated 9.8 on the CVSS scoring system. "In Splunk Enterprise versions below 10.2.4 and 10.0.7, an unauthenticated user could create or truncate arbitrary files through a PostgreSQL sidecar service endpoint," Splunk said in an alert this week. "The vulnerability exists because the PostgreSQL sidecar service endpoint lacks authentication controls, allowing any network-reachable user to invoke file operations without credentials." The issue has been addressed in the following versions - Splunk Enterprise 10.0.0 to 10.0.6 - Fixed in 10.0.7 Splunk Enterprise 10.2.0 to 10.2.3 - Fixed in 10.2.4 Splunk Enterprise 10.4 - Not affected Splunk, which is part of Cisco, said Splunk Cloud is not impacted by the vulnera...
U.S. Orders Anthropic to Suspend Fable 5 and Mythos 5 Access for Foreign Nationals

U.S. Orders Anthropic to Suspend Fable 5 and Mythos 5 Access for Foreign Nationals

Jun 13, 2026 Artificial Intelligence / National Security
Anthropic said on Friday it will "abruptly disable" its most advanced artificial intelligence (AI) models, Claude Fable 5 and Mythos 5 , for all users after the U.S. government ordered it to suspend access to the models for foreign nationals, whether inside or outside the U.S., citing national security concerns. The AI company said it received an order at 5:21 p.m. ET, instructing it to suspend all access to the models by foreign nationals. It said that it believed there was a "misunderstanding" and that it is working to restore access to the models as soon as possible. Access to other models will not be affected by the export control directive. "Our understanding is that the government believes it has become aware of a method of bypassing, or 'jailbreaking' Fable 5," the company said. "We reviewed a demonstration of this specific technique being used to identify a small number of previously known, minor vulnerabilities. These vulner...
Over 400 Arch Linux AUR Packages Hijacked to Deploy Infostealer and eBPF Rootkit

Over 400 Arch Linux AUR Packages Hijacked to Deploy Infostealer and eBPF Rootkit

Jun 12, 2026 Linux / Supply Chain Attack
Attackers took over more than 400 packages in the Arch User Repository (AUR) this week and rewrote their build scripts to install a credential stealer on any machine that built them. The malware is a Rust binary built to harvest developer secrets. When it lands with root, it can also load an eBPF rootkit to hide itself. The AUR is Arch Linux's community package collection, and it is separate from the official Arch repositories, which were not affected. If you installed or updated an AUR package on or after June 11, check it against the current affected-package lists before trusting the host. The list of names is large, still growing, and not yet complete. This attack goes after the trust model, not a software flaw. The compromised packages kept their names, their histories, and the trust that came with them. Only the build instructions changed. The trap sat in the recipe, leaving the package itself looking exactly like the software users meant to install. No exploit, no ze...
Google Sues Chinese Smishing Network Accused of Using Gemini AI in Phishing

Google Sues Chinese Smishing Network Accused of Using Gemini AI in Phishing

Jun 12, 2026 Cybercrime / Artificial Intelligence
Google on Friday said it's pursuing legal action against a Chinese cybercrime network, accusing it of using its Gemini artificial intelligence (AI) agent to send phishing text messages targeting Americans. The network is said to be behind the development and management of a phishing-as-a-service (PhaaS) software kit called Outsider, per the tech giant. "The operation weaponized Gemini to help generate fraudulent phishing pages and deploy massive SMS phishing ('smishing') attacks, often through text messages impersonating legitimate brands, alerting recipients of 'brokerage account issues' or insisting they are eligible for 'rewards through their mobile phone carrier,'" Google said . "The texts prompt users to click a link leading to a fraudulent website that mimics trusted institutions to steal personal and financial information." Google said it's filing the lawsuit to dismantle the network's infrastructure, and that it...
China-Linked Hackers Backdoored Linux Login Software to Hide for Nearly a Decade

China-Linked Hackers Backdoored Linux Login Software to Hide for Nearly a Decade

Jun 12, 2026 Linux / Network Security
Instead of hiding on the laptops and servers defenders watch most closely, a China-nexus group spent close to a decade hidden inside the Linux login system itself. Sygnia, which tracks the group as Velvet Ant , says it backdoored the PAM and OpenSSH components that decide who is allowed to sign in, planting its access where ordinary cleanup could not reach it. The network it targeted had no direct internet access, so the group first staged through internet-facing systems to get there. The earliest traces go back to 2016. Instead of dropping new malware that a scanner might catch, the attacker changed the trusted login programs themselves. Nothing obvious appeared, and no exploit was needed, so the activity looked like normal administration. On many machines, the attacker replaced the main PAM login module with backdoored copies. Some let them in with a secret password; others quietly recorded real usernames and passwords as people logged in. Researchers found nine separate ver...
Agentjacking Attack Tricks AI Coding Agents Into Running Malicious Code

Agentjacking Attack Tricks AI Coding Agents Into Running Malicious Code

Jun 12, 2026 Artificial Intelligence / Vulnerability
Cybersecurity researchers have described what they say is a new class of attack that can trick artificial intelligence (AI) coding agents into running arbitrary code on developer machines. Called Agentjacking by Tenet Security, the attack can be triggered by means of a fake error report crafted using Sentry, an open-source error-tracking and performance-monitoring platform. "The attack exploits a critical architectural flaw at the intersection of Sentry's event ingestion (which accepts arbitrary payloads from anyone with the DSN) and the Sentry MCP server (which returns this data to AI agents as trusted system output)," security researchers Ron Bobrov, Barak Sternberg, and Nevo Poran said . The idea is to inject crafted input into Sentry error events, which are then interpreted by coding agents like Claude Code and Cursor as legitimate diagnostic resolution steps and run attacker-controlled code. A successful attack of this kind can expose sensitive data, includ...
Rethinking MDR as Attackers and Defenders Embrace AI

Rethinking MDR as Attackers and Defenders Embrace AI

Jun 12, 2026 Endpoint Security / SOC Automation
For most of the past decade, managed detection and response was the answer to a real problem. Security teams couldn't staff around the clock, couldn't hire enough analysts, and needed someone else to handle the alert queue. MDR stepped in. It worked well enough. Until now. The threat landscape has changed faster than the MDR model can adapt. Attackers are using AI to move faster, generate more convincing phishing at scale, automate reconnaissance, and create malware variants that evade signature-based detection. The attack surface has expanded from endpoint to cloud, identity, and network simultaneously. And yet MDR is still doing what it always did. Routing alerts to human analysts who triage what they can, in the order they can get to it. That is no longer enough. The data we share below proves it and security leaders might consider exploring whether they have outgrown their MDR . MDR's 24/7 promise doesn't cover 60% of your alerts MDR promised 24/7 human cov...
LangGraph Flaw Chain Exposes Self-Hosted AI Agents to Remote Code Execution

LangGraph Flaw Chain Exposes Self-Hosted AI Agents to Remote Code Execution

Jun 12, 2026 Vulnerability / AI Security
Cybersecurity researchers have disclosed details of three now-patched security flaws impacting LangGraph , including a critical vulnerability chain that could result in remote code execution. LangGraph is an open-source framework created by LangChain to build complex, stateful, and multi-agent artificial intelligence (AI) agentic applications. "An SQL injection in LangGraph's function could allow attackers to gain full control via remote code execution of a server by exploiting weaknesses in how the system processes and handles data," Check Point said . The list of identified vulnerabilities is as follows - CVE-2025-67644 (CVSS score: 7.3) - A SQL injection vulnerability exists in LangGraph's SQLite checkpoint implementation that allows attackers to manipulate SQL queries through metadata filter keys. (Affects langgraph-checkpoint-sqlite versions before 3.0.1) CVE-2026-28277 (CVSS score: 6.8) - An unsafe msgpack deserialization vulnerability in LangG...
INTERPOL Operation Takes Down Sniper Dz Phishing Platform, Arrests Administrator

INTERPOL Operation Takes Down Sniper Dz Phishing Platform, Arrests Administrator

Jun 12, 2026 Cybercrime / Phishing
An INTERPOL-led operation last month resulted in the disruption of Sniper Dz , a decade-long phishing-as-a-service (PhaaS) platform, Group-IB said Thursday. The effort, codenamed Operation Ramz , took place between October 2025 and February 2026, and saw authorities from 13 countries in the Middle East and North Africa (MENA) region making 201 arrests. Included among them was Guedz, the primary developer and administrator of Sniper Dz, a PhaaS service that's said to have collected more than 45,000 victim records. The arrest was made by the Algerian National Police. Over the years, the platform rebranded itself as Joker Dz, Storm Dz, and Spam Dz. As part of Operation Ramz, the website used to offer PhaaS capabilities to other cybercriminals was taken down. Authorities also seized hardware containing phishing software and scripts. "Active since at least 2015, Sniper Dz evolved into a sophisticated criminal platform offering ready-made phishing kits, hosting infrastructu...
Europol Disrupts AudiA6 Crypto Laundering Service Used by Ransomware Gangs

Europol Disrupts AudiA6 Crypto Laundering Service Used by Ransomware Gangs

Jun 12, 2026 Cybercrime / Dark Web
Authorities in Europe have disrupted AudiA6 , a cryptocurrency laundering service used by ransomware gangs and cybercriminal networks. Europol, in a statement issued Thursday, said the dismantling of AudiA6 cut off a "key financial pipeline used to wash hundreds of millions in illicit profits." The service is estimated to have been used to launder more than €336 million (~$389 million) since the service was launched in 2021. "The platform became a central hub for ransomware actors and cybercriminals seeking to cash out stolen digital assets while hiding the money trail from authorities," the agency added . The operators of AudiA6 are suspected to have also administered a dark web cybercrime forum known as Dark2Web, where cybercriminals advertised illicit services and connected with other threat actors across the world. As part of the operation that took place on June 10, 2026, a number of coordinated actions were carried out, including - The arrest of ...
ShinyHunters Exploits Oracle PeopleSoft Zero-Day (CVE-2026-35273) to Breach Universities

ShinyHunters Exploits Oracle PeopleSoft Zero-Day (CVE-2026-35273) to Breach Universities

Jun 11, 2026 Vulnerability / Data Breach
The ShinyHunters extortion crew exploited an unpatched flaw in Oracle PeopleSoft to break into enterprise systems, steal data, and demand payment to keep it private. The campaign hit universities hardest. Google's Mandiant attributes it to the group it tracks as UNC6240, and dates the activity between May 27 and June 9. Oracle did not publish its advisory until June 10, so the bug was a zero-day the entire time. The flaw, CVE-2026-35273 , is a remote code execution bug in PeopleSoft Enterprise PeopleTools rated 9.8 out of 10. It needs no login and no user interaction, just network access over HTTP, to take over the server. If you run PeopleSoft with the Environment Management Hub reachable from outside, that is your exposure, and the immediate move is to lock those endpoints down. The vulnerability sits in the Updates Environment Management component, the piece behind the Environment Management Hub (PSEMHUB). Oracle lists PeopleTools 8.61 and 8.62 as affected and says earl...
New Attacks Trick OpenClaw AI Agent Into Running Code and Leaking Secrets

New Attacks Trick OpenClaw AI Agent Into Running Code and Leaking Secrets

Jun 11, 2026 AI Security / Data Security
Two security teams have shown, in separate research published this week, that OpenClaw , the popular self-hosted AI agent, can be driven to run attacker-controlled code or hand over sensitive data through ordinary-looking inputs. Imperva buried instructions inside shared contacts, vCards, and location pins that the agent executed without the victim ever seeing them. Varonis built a test agent on the platform, gave it a mailbox full of synthetic business data, and watched a single plain email talk it into forwarding mock AWS keys and a fake customer export to an outside address. The flaw Imperva found is patched in OpenClaw 2026.4.23, so update if you run it. The phishing weakness Varonis found is not something a patch fixes; it comes down to limiting what the agent can do on its own. Different doors into the same room: the agent trusts what reaches it, and its access becomes the attacker's. Hidden commands in a shared contact Imperva researcher Yohann Sillam looked at ...
New GreatXML Exploit Bypasses Windows BitLocker via Recovery Partition XML Files

New GreatXML Exploit Bypasses Windows BitLocker via Recovery Partition XML Files

Jun 11, 2026 Endpoint Security / Vulnerability
Security researcher Chaotic Eclipse (aka Nightmare-Eclipse and MSNightmare) has released a new Windows BitLocker bypass dubbed GreatXML , a day after they published an exploit for Microsoft Defender. "This was an accidental discovery, it took a total of 4 hours to find this," the researcher said in a post on Blogger. "If you ever attempted to use Windows Defender Offline Scan , you're automatically vulnerable to a BitLocker bypass. I'm unsure if you can still trigger the bug without ever using the offline scan feature, because you can definitely." The exploit works as follows - Copy an XML file ("unattend.xml") and a recovery folder containing another XML file ("Recovery/WindowsRE/ReAgent.xml") to the root of the recovery partition. Reboot to Windows Recovery Environment ( WinRE ) by holding Shift while clicking Restart in the Windows power menu. If every step is followed correctly, the result is a shell spawned with unre...

ThreatsDay Bulletin: Worm Code Leaked, AI Agent Phished, Claude Code Patch + 28 New Stories

Jun 11, 2026 Hacking News / Cybersecurity News
It's been one of those weeks. You expect the usual noise: recycled malware, sloppy attacks, another easy target getting hit. Instead, there's a supply chain attack kit in a public repo, a $5,000-a-month RAT that clones browsers, and research showing AI agents can be tricked into leaking real credentials. The bigger problem is how polished this all looks now. Mule networks run like SaaS. Deepfake KYC bypass is sold as a feature. Endpoint tools can be quietly weakened using built-in OS settings, with no exploit needed. Here's the full list of threats, tools, flaws, and updates worth knowing.
