It’s Monday again. This week’s threat list looks painfully familiar: abused integrations, fake tools, poisoned websites, ransomware crews trying to shut down security tools, and mobile malware asking for way too much control. The annoying part is how little of this feels new. Weak credentials, sketchy downloads, browser extensions with too much access, and WordPress sites are used to push more attacks. Nothing clever. Just sloppy, cheap, and effective. Here’s the Monday recap. Let’s get into the week’s mess. ⚡ Threat of the Week FortiBleed Campaign Identifies Over 80K Targets — A large-scale campaign codenamed FortiBleed has systematically targeted and compromised Fortinet FortiGate firewall and SSL VPN gateway devices worldwide. According to SOCRadar, it has been running since at least February 2026, with over 80,000 devices identified with working usernames and passwords that have been tested by suspected Russian-speaking threat actors using automated tools running around...

The internet did not break this week. It got used exactly as designed, which is worse. Searches were siphoned through shady browser add-ons. AI chat links turned into malware delivery paths. macOS attacks ran in memory and left almost nothing behind. Cloud agents looked like helpers until attackers treated them like open shells. Add exposed edge gear, poisoned packages, cash courier scams, stealers, loaders, and phishing that barely bothers pretending anymore. Here’s the full mess.

Breaches don't always start with a zero-day. An exposed admin panel can get brute-forced, or credentials reused from a previous attack. But when a vulnerability does drop — like MongoBleed earlier this year, which let attackers pull credentials and session tokens from server memory without authentication — anything internet-facing is immediately at risk. With time-to-exploit now down to a single day, the question isn't just how fast you can patch. It's why the service was exposed in the first place. The team at Intruder analyzed 3,000 attack surfaces to find out how much of a typical organization's attack surface consists of services that have no reason to be there. We grouped what we found into four categories — HTTP panels, risky ports and services, databases, and publicly accessible files and information. The full findings, including breakdowns by company size and industry, are in our 2026 Attack Surface Management Index . How widespread is the problem? ...

A flaw in the Google Cloud Vertex AI SDK for Python let an attacker with no access to a victim's project hijack the victim's machine learning model upload and run code inside Google's serving infrastructure. Palo Alto Networks Unit 42, which found and reported the bug through Google's bug bounty program, calls the technique " Pickle in the Middle " and said it saw no exploitation in the wild. Google has patched it; if you use the SDK, update to version 1.148.0 or later. The attacker needed only a Google Cloud project of their own and the victim's project ID, which is often public. No credentials, no phishing, no foothold in the target. The flaw was in how the SDK chose a temporary Cloud Storage bucket for model uploads. If a user did not set a bucket, the SDK generated a predictable name from the project ID and region, such as  project-vertex-staging-region . It checked whether that bucket existed, but not whether the victim owned it. Because buc...

Security teams have never had more IP data at their disposal. Every day, analysts ingest enrichment feeds, geolocation data, reputation scores, telemetry, and threat intelligence from a growing ecosystem of vendors and platforms. Yet despite this abundance of information, many organizations continue to face a fundamental challenge: sifting through the noise to understand who is behind an IP and what action should follow . Case in point: a recent industry study of more than 200 security practitioners conducted by Spur Intelligence found that anonymizing infrastructure - including VPNs and residential proxy networks - now appears in nearly every security incident. At the same time, the study showed that many organizations admit they lack the visibility, context, and operational workflows needed to make effective decisions based on that IP data. The findings support a broader industry trend: a reactive approach to managing IP-based risks. The Rise of Anonymized Infrastructure...

Bad actors are exploiting multiple security vulnerabilities in Fortinet FortiSandbox, according to threat intelligence firm Defused Cyber. In a post shared on X, the company said it has observed exploitation of CVE-2026-39813, CVE-2026-39808 , and CVE-2026-25089 over the past 24 hours. CVE-2026-39813 (CVSS score: 9.1) refers to a path traversal vulnerability in FortiSandbox JRPC API that could allow an unauthenticated attacker to bypass authentication via specially crafted HTTP requests. The second flaw, CVE-2026-39808 (CVSS score: 9.1), is a case of operating system command injection that could allow an unauthenticated attacker to execute unauthorized code or commands via crafted HTTP requests. Both vulnerabilities were patched by Fortinet in April 2026. CVE-2026-25089 (CVSS score: 9.1), on the other hand, was fixed last week, with Fortinet describing it as an operating system command injection impacting FortiSandbox, FortiSandbox Cloud, and FortiSandbox PaaS WEB UI that co...

Cybersecurity researchers have flagged two previously undocumented Windows variants of what was believed to be a Linux-only backdoor called SprySOCKS . "The Windows variants discovered are internally marked as WIN_DRV and WIN_PLUS," ESET said in a report shared with The Hacker News. "Both come with a hard-coded C&C [command-and-control] configuration and support communication over TCP, UDP, and WebSocket protocols." Like its Linux counterpart, the Windows versions support more than 30 commands to facilitate system information collection, process enumeration, service management, and file system operations. WIN_DRV has also been found to utilize kernel drivers to conceal the malware's network connections, processes, files, and registry keys. In addition, the variant enables TCP traffic diversion that allows the malware operators to send commands to the backdoor through a random TCP port on the victim's device without exposing the backdoor's act...

The North Korean state-sponsored hacking group known as ScarCruft (aka APT37) has been observed using spear-phishing messages impersonating Microsoft Account security notifications to deliver a new malware called NarwhalRAT . "The attack email contained a message impersonating an MS account security alert," the Genians Security Center (GSC) said . "It was designed to create concern over possible account compromise and OTP abuse, thereby inducing the recipient to execute the attachment." "The email body instructed the recipient to refer to the attached advisory. However, the actual attachment was not an HWP [Hangul Word Processor] document, but a ZIP archive that contained a malicious LNK file." The email message claims "abnormal activity" related to repeated generation of one-time passwords, passing it off as a phishing attempt aimed at the target's Microsoft Account by a third-party, and urging them to change their password. The end ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a security flaw impacting LiteSpeed cPanel Plugin to its Known Exploited Vulnerabilities ( KEV ) catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by June 18, 2026. The vulnerability in question is CVE-2026-54420 (CVSS score: 8.5), which has been described as a case of privilege escalation. It allows a user with FTP or web shell access to escalate privileges to root on shared hosting servers running CloudLinux or CageFS. "LiteSpeed cPanel plugin before 2.4.8 (as distributed in LiteSpeed WHM PlugIn before 5.3.2.0) mishandles symlinks provided by a user with FTP or web shell access on a shared hosting server running CloudLinux/CageFS," according to a description of the vulnerability in CVE.org. It's currently not known how the vulnerability is being exploited in the wild and if any of those attacks have been successful, but LiteSpeed has urged users to ...

A China-linked espionage group hid inside North American medical, academic, and military research networks for more than a year, quietly stealing sensitive research and defense email. The way in was a backdoor on their REDCap research servers that stole login credentials. The exfiltration was the unusual part: the attackers rewired the victims' own Google Workspace rules to copy any message matching their keywords to an inbox they controlled. Google's Threat Intelligence Group (GTIG) laid out the campaign in a report published this week and attributes it with high confidence to a cluster it tracks as UNC6508. The actor and its REDCap backdoor are not new names; Google first surfaced both in February , in a wider report on state-backed attacks against the defense sector. It did not name the victims, describing them only as multiple organizations across the US and Canada: clinical providers, academic centers, military health institutions, advocacy groups, and health regul...

Cybersecurity researchers have flagged two malicious cyber campaigns that exhibit similarities with a persistent North Korean threat cluster known as Contagious Interview (aka Famous Chollima, HexagonalRodent, and Void Dokkaebi). According to a report published by Proofpoint, the threat actor has been found orchestrating phishing campaigns using developer role recruitment or code review themes to target nearly 100 organizations in finance, cryptocurrency, education, technology, and several other sectors. The activity has been codenamed UNK_DeadDrop . "The infection chain begins with emails containing links to actor-controlled GitHub repositories hosting malicious scripts that result in the execution of cross-platform malware for macOS, Linux, and Windows, including an open-source Go framework named Overlord ," Proofpoint researchers Saher Naumaan and Carlos Rubio said . A crucial aspect connecting the campaign to Pyongyang is the use of Microsoft Visual Studio Code (...

A default low-privilege account on a LiteLLM proxy can climb to full admin and run code on the server by chaining three vulnerabilities, researchers at Obsidian Security disclosed LiteLLM is a widely deployed open-source AI gateway that brokers calls to more than 100 model providers behind one OpenAI-compatible interface. A server takeover exposes every provider key it holds, the secrets that decrypt its stored credentials, and every prompt and response passing through it. Obsidian rates the full chain CVSS 9.9, in the Critical range. BerriAI , the maintainer, included the complete fix set in LiteLLM v1.83.14-stable, which GitHub lists as released May 2. Upgrade to that release or later to close the three-CVE chain. The three bugs The first link is CVE-2026-47101 , an authorization bypass. When a regular user (an internal_user) generates a virtual API key, LiteLLM stores the caller-supplied allowed_routes field without checking it against the user's role. The field is...

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 high-severity vulnerability, tracked as CVE-2026-11645 (CVSS score: 8.8), has been described as an out-of-bounds memory access in V8, Chrome's JavaScript and WebAssembly engine. Google acknowledged that an "exploit for CVE-2026-11645 exists in the wild," but stopped short of sharing addition...

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...

Cybersecurity researchers have discovered a network of 152 Google Chrome extensions that act as new tab live wallpaper add-ons to distribute a potentially unwanted program (PUP) family. The cluster spans 38 separate Chrome Web Store publisher accounts and three brand backends: tabplugins[.]com, yowgames[.]com, and chromewallpaper[.]com. They have been collectively installed 105,000 times. The names of some of the extensions are listed below - Neymar - Football Live Wallpaper (laafpeklcnlfmjaofbndehkjpnccbhek) Satoru Gojo Manga Live Wallpaper (mnpacdigbockiilmilhbedciadenfdnb) Porsche 911 - Sports Car Live Wallpaper (dead service worker) (iedplnnolciaofkakkjmcojnmklpfikg) Satoru Gojo Live Wallpaper (ipiabbhciknabpoihaakdahgghllelpj) Hello Kitty Wallpapers HD New Tab (hijpkhinofkdobfagfbobnnoihmopgkk) Pusheen Cat Wallpapers HD New Tab (famchdjojcnakamhkddkpaglnkonkfnl) Peach & Goma Wallpapers HD New Tab (nomekamioepglinefhenifnbegjhfiai) Spider-Man Miles ...

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 ...

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 ...

Palo Alto Networks has revealed that it has observed "active exploitation" of a recently disclosed PAN-OS vulnerability by an unknown threat actor to obtain unauthorized access to GlobalProtect portals. The vulnerability in question is CVE-2026-0257 (CVSS score: 7.8), an authentication bypass flaw affecting the portal and gateway components of PAN-OS software that could be exploited by bad actors to set up VPN connections. According to the network security company, the security defect could be exploited by a bad actor to bypass security controls and initiate VPN connections. The vulnerability has been exploited in the wild in limited attacks, with initial activity observed on May 17, 2026. It's currently unknown who is behind the exploitation efforts. "No post-access behavior or lateral movement has been identified as of this time," Palo Alto Networks said . "Only a small portion of the probed devices actually established VPN sessions, resulting ...

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...

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...
