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 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 goal o...

Cisco has released security updates for a medium-severity security flaw in Catalyst SD-WAN Manager that has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-20262 , carries a CVSS score of 6.5 out of 10.0. "A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an authenticated, remote attacker to create a file or overwrite any file on the filesystem of an affected system," Cisco said in an advisory. The issue, the networking equipment company added, stems from inadequate validation of user-supplied input during a file upload process. An attacker could exploit this behavior to create or overwrite any file on the underlying operating system by sending crafted HTTP requests to an affected API endpoint. This, in turn, could be weaponized to elevate to the root. However, successful exploitation hinges on the attacker already having valid credentials with at least write access. The vulnerab...

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...

A single click on a trusted Microsoft link could have let an attacker pull emails, calendar details, and indexed files out of Microsoft 365 Copilot Enterprise Search. Researchers at Varonis Threat Labs chained three bugs into a one-click exfiltration path they call SearchLeak . Because the link pointed to a real microsoft.com domain, traditional anti-phishing and URL filtering tools were unlikely to flag it. No prompt, no password, no second click. Microsoft assigned CVE-2026-42824 and marked it critical; the CVSS scores ran lower and disagreed, 6.5 from Microsoft and 7.5 from the National Vulnerability Database . The company mitigated the flaw on its backend, so customers have nothing to worry about, and Varonis presented a proof-of-concept, not observed exploitation. Three bugs, one click Microsoft's advisory describes the flaw as a command injection that can expose information over a network. In practice, SearchLeak stacks one AI-specific weakness on two old web bugs, ...

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.

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...
