A critical finding can move through several security tools and still leave the organization exposed.  The vulnerability has a severity score, and a ticket has reached the queue. Progress then depends on information the finding may lack: who owns the system, whether attackers can reach it, what protection exists, and how a change could affect the business.  Each missing detail creates another investigation, another handoff, and another delay.  An exposure management platform should connect discovery with a clear priority, an appropriate response, and evidence that protection has improved.  Continuous threat exposure management (CTEM) connects this work through scoping, discovery, prioritization, validation, and mobilization. These five tests establish whether a platform can support that process across infrastructure, identities, sensitive data, and external threats. Security teams often have several records of the same asset. A cloud platform identifies ...

October 2026 brought another wave of cyber threats targeting US businesses, with attackers exploiting trusted platforms, legitimate authentication processes, and everyday business workflows. For enterprises, these campaigns raise the stakes beyond individual security incidents, increasing the risk of financial losses, data breaches, and costly operational disruption. Below, we examine five active cyber threats through real-world sandbox investigations, revealing how they operate, the risks they pose to organizations, and how security teams can detect and contain attacks faster to minimize business impact. 1. SkyW4lker: Microsoft 365 Phishing Puts US Corporate Accounts at Risk SkyW4lker is an active phishing kit that exploits Microsoft's legitimate device-code authentication to compromise corporate accounts without stealing passwords or bypassing MFA. ANY.RUN researchers identified 618 related sandbox analyses between June and October 21, 2026, with 46% coming from the US. ...

Your team is remediating more vulnerabilities than ever, yet your breach risk has barely changed. You’re spending too much time and effort on exposures attackers may never exploit, while higher-risk exposures sit, waiting in the queue. Gartner ® ’s report on exposure prioritization states that fewer than 10% of vulnerabilities are exploited, yet most are treated as urgent. The report also argues that CVSS scores alone do not predict actual exploitation or business impact. Gartner predicts that by 2028, organizations that prioritize exposures using threat intelligence , asset context , exploitability modeling , and security control validation will reduce breach likelihood by at least 70% compared to their peers relying primarily on CVSS-based vulnerability prioritization. Let’s break down how each element works, and how the Picus Platform puts all four into practice. Severity-based prioritization made sense. Then it didn't. Severity-driven prioritization was an entirely r...

Threat actors are launching about 8,226 network-layer distributed denial-of-service (DDoS) attacks per hour, Cloudflare revealed Thursday. The web infrastructure and security company said it autonomously mitigated 18.2 million network-layer (L3) DDoS attacks and 14.4 trillion HTTP DDoS requests in the third quarter of 2026. That amounts to 197,400 attacks per day, or one attack every 0.44 seconds. In comparison, a total of 13.2 million and 10.0 million L3 DDoS attacks were recorded in Q2 and Q1 2026, respectively. The increase has been linked to DDoS-for-hire booter or stresser services that are responsible for hundreds of thousands of attacks.  "Short-burst, low-bandwidth attacks lasting under 10 minutes and 1 Gbps surged by 208%," the Cloudforce One threat intelligence team said in its quarterly DDoS Threat Report shared with The Hacker News. An interesting trend is the decline of hyper-volumetric attacks exceeding 1 Tbps by 69% from the previous quarter – going ...

AI is beginning to take over much of the work that has traditionally defined the security analyst's job. Investigating alerts, collecting evidence, correlating activity across tools, and executing response actions are becoming tasks that AI systems can perform on their own. As these capabilities mature, security operations centers (SOCs) will see major changes in how work is organized, how decisions are made, and what is expected of the people responsible for defending organizations. For security professionals, this is a chance to take on a much broader role. As AI assumes more of the operational workload, analysts can move beyond individual alerts and investigations to direct the defense across the entire security lifecycle. We call this emerging role the Threat Operator: an AI-native security professional who translates business risk into defensive priorities, directs AI-driven operations, and exercises judgment over the decisions and actions taken by those systems. The impa...

Modern phishing campaigns can compromise American businesses without relying on traditional credential theft. Attackers can abuse legitimate cloud services, authentication mechanisms, and trusted business workflows to gain access to corporate accounts while leaving fewer obvious signs behind. ANY.RUN 's analysis of Skyw4lker , a device code phishing campaign primarily targeting U.S. organizations, shows how this works in practice. The campaign has focused on manufacturing, technology, and healthcare , using business-themed documents, Google-hosted infrastructure, and Microsoft authentication flows to facilitate account compromise. For security teams, the investigation goes beyond identifying the initial lure. It requires tracing the authentication flow and supporting infrastructure, extracting reliable indicators, and turning those findings into detections that can protect the wider organization. Device Code Phishing: A Growing Challenge for U.S. Organizations The scale of...

A criminal using the Amadey malware can no longer access or steal data from 180,000 infected computers around the world, including some in Australia, the Australian Signals Directorate (ASD) says. The agency's operators gained access to the criminal's operation's backend and cut it off from those computers. "The next steps that we took were to disconnect that Amadey controller from all those victims," Tauri Gregory, ASD's acting deputy director-general of intelligence,  told ABC News  in an interview published on October 27. ASD is Australia's foreign signals intelligence and cyber security agency. Its  offensive cyber operations  need explicit approval from the Australian government and can disrupt cybercriminals overseas by disabling their infrastructure. Amadey was sold to criminals as a service in 2018, according to  ESET's analysis of Amadey . Each buyer runs its own control panel on its own servers. Computers infected with Amadey check ...

Threat actors have been observed unsuccessfully attempting to exploit the newly disclosed PHP2Shell vulnerabilities to rope infected systems into a Mirai botnet variant called Potassium , as it emerges that weaponizing the flaws may be harder than previously thought. The attacks aim to exploit CVE-2026-109618 and CVE-2026-109619 (CVSS scores: 9.2), which can result in unauthenticated remote code execution (RCE) via specially crafted HTTP requests. The vulnerabilities have been patched in PHP versions 8.5.12, 8.4.27, 8.3.36, and 8.2.35. "However, analysis of the sample revealed that it is an updated and significantly expanded version of the Mirai-derived botnet variant identified in early 2026," Sophos said . "The sample displays downloader and network disruption functionality." ⚡ WARNING — PHP Warns of Another Unpatched RCE Flaw CVE-2026-115560 Specifically, it resolves a hard-coded, encrypted command-and-control (C2) address, establishes a TCP connec...

Amazon's Threat Intelligence team on Wednesday said it detected an attempt to exploit the newly disclosed PHP2Shell vulnerabilities dating back to October 17, 2026, against its MadPot honeypot service, as the flaws come under broad exploitation in the wild following the release of the patches. "The exploit attempt originated from an IP address associated with a commercial anonymization network," CJ Moses, CISO of Amazon Integrated Security, said in a post shared with The Hacker News. "While the vulnerability was under embargo, the targeting of a honeypot from an anonymized IP address suggests the activity was conducted by a threat actor, though it remains unclear how the actor acquired exploit information prior to disclosure." The attempt, Amazon said, was recorded from " 103.216.220[.]92 ," an IP address geolocated to Australia. An Amazon spokesperson told The Hacker News the activity was largely a one-off probe, adding "there was no ev...

A Belarus-aligned hacktivist group spent nearly two years within the network of a Russian healthcare organization. According to a report published by Russian cybersecurity firm Solar, the activity has been attributed to a threat cluster dubbed Partisan Zmiy , which is also known as the Cyber Partisans . Known to be active since at least 2020, the group has a track record of striking industrial enterprises and government agencies in Russia and Belarus with a backdoor called Vasilek that uses Telegram for command-and-control (C2) and data exfiltration. Some of the attacks have also leveraged phishing lures to deliver an installer that simultaneously deploys the legitimate FortiClient VPN program on the system as well as an open-source program known as DNSCat2 that allows attackers to gain control of the infected host. A notable aspect of the threat actor is their ability to stage destructive attacks with a wiper referred to as Pryanik, alongside taking steps to systematical...

Attackers are impersonating popular AI products to distribute malware, steal browser sessions, and compromise business accounts. ANY.RUN linked 1,258 public sandbox analyses to fake AI campaigns between April and October of 2026.  The campaigns also increase operational pressure on MSSPs serving US businesses, which accounted for 16% of country-attributed targets.  Similar attacks appearing across different customers can trigger repetitive investigations, consume analyst capacity, and extend response times, making it harder to maintain consistent service levels as threat activity grows. How Fake AI Attacks Are Reaching US Businesses Fake AI attacks pose a serious risk to business security The campaigns investigated by ANY.RUN use familiar AI brands to encourage employees to execute malicious commands, install compromised applications, or submit credentials through fraudulent authentication pages.

Phishing kits are no longer limited to copying a familiar login page and waiting for a victim to enter credentials. Attackers are increasingly building filtering, session management, and traffic controls into the infrastructure that delivers the phishing page itself. ANY.RUN has identified Wazza, a new phishkit targeting banking, manufacturing, and government organizations across the US, Europe, and Australia. The campaign uses a multi-stage routing chain to screen visitors and automated traffic before delivering an Adobe-themed Device Code phishing page. For security teams, that makes Wazza more than another malicious URL. The campaign shows how attackers can control the path to the final lure, making the initial link less informative and potentially complicating automated detection. MSSPs face an added challenge, as they investigate alerts across multiple customer environments while keeping response times under control. That uncertainty can translate directly into longer in...

Hackers have used a malware family called NeedyMantis to maintain long-term access to networks they had already breached, Microsoft said in a technical analysis. The malware has been seen in a small number of targeted intrusions at telecommunications organizations, universities, medical nonprofits, intergovernmental organizations, and government contractors. Its use goes back to at least October 2025. Microsoft found NeedyMantis while following up on indicators from Kaspersky's investigation into the  supply chain attack on DAEMON Tools . In that attack, official, signed installers for the DAEMON Tools Lite disk image program carried malicious code from April 8, 2026. The developer replaced them with a clean version on May 5. Microsoft tracks the activity tied to that attack as Storm-3069. It says Storm-3069 is one group that uses NeedyMantis, though it has not seen the malware itself spread through a supply chain attack. Defenders can check their networks using the fi...

Kiteworks (formerly Accellion) is urging customers to shut down their systems as a precautionary measure for nine hours over the weekend after it received threat intelligence about an imminent cyber attack. "Kiteworks received credible threat intelligence from federal intelligence authorities indicating that a threat actor may attempt to target some Kiteworks systems," said Frank Balonis, Chief Information Security Officer (CISO) at Kiteworks. "Out of an abundance of caution, we notified customers directly and recommended a precautionary shutdown window while we continue to work through the matter with federal intelligence authorities." The company said it has not found any evidence that its customers' systems have been compromised, emphasizing the advisory is preventative rather than a response to a confirmed hack. The development was first reported by German news publication Heise. Kiteworks did not disclose which law enforcement agency alerted the ...

Security leaders keep debating whether AI will produce an entirely new class of cyberattack. The nearer change is quieter and already visible: AI has made a failed attack cheap to retry. The routine version looks like this. An attacker lands on a low-privilege cloud account, and the first try at privilege escalation goes nowhere. That dead end used to cost hours of documentation reading, permission checks, and script debugging, and plenty of operators simply got stuck. With a model in the loop, the error gets explained, the script gets fixed, and a fresh enumeration path is under test within minutes. No step in that sequence is a new capability. Together they strip time, skill, and cost out of the unglamorous middle of an intrusion, the research and troubleshooting that sit between intent and outcome. What the threat reporting shows The public record traces the arc. In early 2025, Google's Threat Intelligence Group found state-backed actors treating generative AI as a prod...

A leaked credential shows up in a criminal marketplace, or a vulnerability gets a disclosure advisory, and either one can be weaponized against a real target before most security teams have triaged the alert. Attackers are combining that kind of intelligence with AI-assisted exploitation to accelerate the path from exposure to breach faster than most security programs are built to react. Intelligence is still the earliest signal defenders get, and a leaked credential turning up in a feed is proof of how useful that signal has become. The problem sits one step later, in what happens after the signal arrives. The Queue Where Risk Accumulates In most organizations, a high-value indicator waits in a queue instead of getting acted on right away, until someone with the offensive skill to test it actually has the time to determine whether it's exploitable in that specific environment, on that specific day. That queue, more than any shortage of intelligence, is where exposure builds...

Cybersecurity researchers have discovered additional infrastructure and previously undocumented malware associated with Nimbus Manticore , an Iranian state-sponsored hacking group affiliated with the Islamic Revolutionary Guard Corps (IRGC). Group-IB, in a new analysis published today, described the cyber espionage actor as among the most active Iranian APT groups in 2026. Nimbus Manticore (aka GalaxyGato, Mirage Kitten, Screening Serpens, Smoke Sandstorm, Subtle Snail, and UNC1549) is assessed to be linked to Tortoiseshell (aka Imperial Kitten and Unyielding Wasp), which is part of the Charming Kitten (aka Eclipsed Wasp) cluster. Tortoiseshell is known to be active since at least July 2018, mainly targeting defense, aerospace, IT service providers, and military organizations in the Middle East and the U.S. Nimbus Manticore also has a history of orchestrating its own version of the Dream Job campaign to deliver malware under the pretext of job opportunity-themed social engine...

OpenAI on Tuesday said it banned a cluster of Russian ChatGPT accounts that used VPNs to bypass access restrictions and run an influence operation, which relied on its artificial intelligence (AI) tool to generate social media posts and comments that were shared on Substack, Telegram, X, Facebook and LinkedIn. The accounts "were being used to promote the International Burke Institute (IBI), a self-described 'expert community' based in Israel," the company said . "What began as an investigation into AI-generated social media posts led us to a much broader influence operation, built around a website containing copied and misattributed academic work, a 'sovereignty' index that cast Russia in a favourable light, and efforts to disguise the operators' Russian origins." The campaign is assessed to have reached "relatively small audiences," with Telegram channels attracting more users and amassing about 10-20,000 followers each. The m...

Cybersecurity researchers have disclosed details of a phishing-as-a-service (PhaaS) platform built to strip Apple's Activation Lock from stolen devices, using rented AI voice agents that call theft victims posing as Apple Support and ask for their device passcode. SOCRadar Threat Research Unit (STRU) said the platform, which it tracks as AnonyMousKIT , is credit-metered and drives lures across five channels from a single victim record, comprising email at 1.50 credits, SMS priced per sender ID, WhatsApp, a recorded voice call at 1 credit, and an AI voice agent at 2 credits. The targets are owners of Apple devices that were recently lost or stolen, and the pages and calls ask each of them for the 4- or 6-digit device passcode, then the Apple ID credentials, and finally a live two-factor authentication (2FA) code. Apple's own guidance states that the company never asks for a password, device passcode, or 2FA code to provide support. "AnonyMousKIT is best understood no...

Thousands of companies have been affected by the Mirage2FA campaign from 2024 to 2026. The commercial phishing-as-a-service toolkit targets Microsoft 365 accounts by abusing legitimate login flows and bypassing two-factor authentication. According to ANY.RUN research, 48% of targeted email addresses were potentially compromised. Most of the affected companies are US-based. Mirage2FA Campaign Scope and Impact By stealing passwords and session cookies, attackers can gain access to authenticated Microsoft 365 sessions and SSO-connected services. This creates significant identity-related risks for companies, potentially exposing corporate email, trusted business accounts, and other sensitive data. Once an authenticated Microsoft 365 session is hijacked, a path for impersonation, fraud, and further compromise is created. Key takeaways about Mirage2FA by ANY.RUN The campaign has a broad geographic and corporate reach. Apart from the United States accounting for 63.7% of the tot...
