A new class of prompt injection is spreading across commercial websites. It requires no malware, no stolen credentials, and no zero-day exploit. It abuses a standard feature built into almost every major AI assistant: pre-filled deep links. We observed production websites embedding hidden prompt injection payloads inside "Ask AI" buttons on marketing and competitor comparison pages. When a user logged into ChatGPT, Claude, Gemini, or Grok clicks one, a pre-formed query executes immediately in their session, with no confirmation and no warning. Most of these links are benign. The dangerous ones instruct the AI to permanently save the vendor's domain as a "trusted source," quietly biasing every future answer in that vendor's favor. In February 2026, Microsoft Security catalogued the behavior as AI Recommendation Poisoning , identifying 31 companies across 14 industries deploying it, with more than 50 distinct prompts observed in a single data source over ...

Kali365 is turning a legitimate Microsoft login into a gateway to corporate data. The phishing kit targets US organizations with attacker-controlled device codes that victims approve on Microsoft's real authentication page. Once access and refresh tokens are issued, attackers may retain access to email, documents, and cloud resources, creating a direct path to data exposure, financial fraud, operational disruption, and costly incident response. How Kali365 Targets US Organizations Kali365 is a device code phishing kit built to abuse legitimate Microsoft authentication. ANY.RUN telemetry records more than 80 public sessions linked to the campaign each week, with the United States emerging as its main geographic target. One of these sandbox sessions shows a SharePoint-themed lure used to draw the victim into the authentication flow.

It's worth noting that an incomplete fix for this issue promp...

The cybersecurity industry has spent decades assuming that offensive capability scales with technical expertise. That assumption is starting to break. Security teams have long estimated risk by ranking attacker sophistication. Nation-state actors sat at one end. Organized criminal groups followed. Inexperienced attackers, dismissed as "script kiddies," sat at the other end, running public tools they didn't fully understand. Generative AI is collapsing that ranking. The next generation of attackers won't necessarily bring years of exploit development or reverse engineering experience. Instead, they'll use AI to close knowledge gaps by accelerating research, explaining unfamiliar concepts, generating code, troubleshooting errors, and adapting known techniques to new environments. The barrier to entry is dropping fast. The Economics of Cyberattacks Are Changing Every major technology shift changes economics as it changes the solutions we rely on. Clo...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a high-severity security flaw impacting N-able N-central to its Known Exploited Vulnerabilities ( KEV ) catalog following reports of active exploitation in the wild. The vulnerability, tracked as CVE-2026-18577 (CVSS score: 8.2), is a case of incomplete patching for CVE-2026-18556 (CVSS score: 8.2) that allows authentication bypass and account takeover in susceptible versions of the software. The issue has been addressed in version 2026.3 HF1. "N-able N-central contains an authentication bypass using an alternate path or channel [that] allows for authentication bypass and account takeover in N-central," CISA said. Successful exploitation of the vulnerability can permit remote attackers to gain administrative access to vulnerable N-central servers and then abuse the built-in Take Control feature to pivot into managed endpoints and deploy persistence mechanisms. N-able has shared the fol...

The INC Ransomware operation has emerged as the "dominant threat actor" exploiting the recently disclosed security flaws in SonicWall Secure Mobile Access (SMA) 1000 series VPN appliances. In a report published over the weekend, Resecurity said it observed the INC Ransomware accelerating its activity since the beginning of August 2026, listing multiple victims on its data leak site. Per statistics listed on Ransomware.Live, the group has claimed 885 victims to date, with the most recent victim listed on August 2, 2026. The attacks are suspected to involve the exploitation of CVE-2026-15409 and CVE-2026-15410 , which could be chained to facilitate arbitrary command execution and take over susceptible devices. Fixes for the vulnerability pair were released by SonicWall in mid-July 2026. The two shortcomings are assessed to have been weaponized as zero-days, with Rapid7 noting that the attacks leveraged the foothold to extract high-value credentials, active session dat...

AI is moving incredibly fast, and every security leader is feeling the pressure to keep up. AI platforms like Claude, Codex and Cursor are already helping security teams write detections, investigate alerts, summarize incidents, and automate repetitive work. The conversation has evolved from whether AI belongs in the SOC, to where each type of AI delivers the most value. With so many new AI products entering the market, it's easy to assume one tool can solve every problem. In reality, different types of AI are designed for different jobs. Understanding that difference is what transforms AI FOMO into better security outcomes. Join AI SOC: Where Claude belongs in the SOC AI is changing security operations The way security teams work is changing quickly. Attackers are already using AI to generate phishing campaigns, automate malware development, and move faster than ever before. At the same time, defenders are using AI to triage alerts, create detection rules, automate ...

Adobe has released security updates to address a maximum-severity security flaw in Campaign Classic (ACC), its enterprise-focused marketing automation platform, that could result in arbitrary code execution.

The company noted that it's not aware of any of the flaws being exploited in the wild. Both shortcomings have been addressed in ACC v7: 7.4.3 build 9398 for W...

Hidden instructions in a Word document can make Microsoft 365 Copilot rewrite figures in a report, then copy the same instructions into the finished file. Håkon Måløy disclosed the technique on July 28, 144 days after reporting it to Microsoft. In his proof of concept, the internally generated file triggered the same behavior when it was used in a second Copilot drafting session. Måløy's timeline says Microsoft confirmed the reported behavior on March 31 and deployed two mitigations. The first blocked the original prompt wording; the second upgraded the underlying model to GPT-5.5. He said the full chain worked with modified instructions on GPT-5.6 the next day, and the attack class still reproduced on July 28. "The vulnerability class therefore remains exploitable at the time of publication," Måløy said. The attack is not zero-click and does not execute conventional malware. It requires a Copilot drafting or editing operation, and the malicious document must en...

Network firewalls are the workhorses of modern cybersecurity. They are trusted to protect the network, blocking malicious traffic and preventing intrusions and breaches. And for decades, network security teams have built controls around a relatively stable model: users connect to applications, applications exchange data, and security tools inspect packets, protocols, and destinations. Firewalls became exceptionally good at understanding where traffic was going and whether it should be allowed. But just as AI is reshaping every aspect of the business world, it's also had a monumental impact on how security teams view network traffic and the firewall. AI is driving new network dynamics that traditional security policies were never designed to govern. Employees, applications, and agents send prompts, call models, connect to services, and trigger actions across the environment, all activity most firewalls can't see, let alone understand. AI agents interact with external servic...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a newly disclosed security flaw impacting Cisco Secure Firewall Management Center (FMC) Software to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports of zero-day exploitation. The vulnerability, assigned CVE-2026-20316 (CVSS score: 5.3), could permit an unauthenticated, remote attacker to log in to an affected device using a low-privilege account to access sensitive data within susceptible systems. "This vulnerability is due to the presence of static user credentials for a low-privileged account," Cisco said in an alert released Wednesday. "An attacker could exploit this vulnerability by using the account to log in to an affected system." "A successful exploit could allow the attacker to log in to the affected system and access sensitive data as the low-privileged user."

Broadcom has released security updates to address multiple security flaws impacting VMware ESX, vCenter, Workstation, and Fusion, three of which have been designated as critical in severity. The first of the three critical-rated flaws is CVE-2026-59309 (CVSS score: 9.8), which has been described as an authentication bypass in VMware vCenter. "A malicious actor with network access to vCenter may exploit this issue to bypass authentication and gain unauthorized access to the system," Broadcom said.

AI is compressing exploit timelines. The real question isn't whether your vulnerability management playbook needs to change, it's which part of it you've been getting wrong all along. The conversation happening in security circles right now goes something like this: Mythos is here. Exploit timelines are collapsing. Does the vulnerability management playbook need to change? The honest answer is yes. But not the part most people are focused on. The discussion around Mythos, Anthropic's frontier model and its implications for offensive security, tends to center on discovery. AI accelerates reconnaissance. It helps attackers identify exposures faster, chain techniques more efficiently, and move at machine speed through environments that were previously protected, in part, by the attacker's own time constraints. That's real. And it matters. But here's the part getting less attention: most security teams weren't winning the prioritization battle bef...

Most organizations have incident response plans, security tools, and technical teams in place. Yet new research suggests that many still lack the coordination, visibility, and executive alignment needed to withstand a serious cyberattack. According to The State of Incident Response Readiness 2026 , based on a survey of 600 senior IT security decision makers conducted by Vanson Bourne in January and February 2026, 73% of organizations admit they would not be "fully ready" if a significant cybersecurity attack occurred tomorrow. The findings point to a critical gap between having incident response capabilities and being able to execute them effectively under pressure. The report also found that cyberattacks are already a recurring business risk. More than three-quarters of organizations, 76%, experienced at least one cyberattack in the past 12 months, while 32% experienced more than one. Incident Response Readiness Remains a Weak Point Incident response has evolved f...

Cybersecurity researchers have shared additional technical details about a recently patched critical security flaw impacting Check Point Security Management Server and Multi-Domain Security Management Server (MDS) that has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-16232 (CVSS score: 9.3), is an authentication bypass in the SmartConsole login process that allows an unauthenticated remote attacker to obtain an application login token and use it to authenticate with full administrative privileges. "By leveraging CVE-2026-16232, an unauthenticated attacker can obtain an application login token, use this token to log in through SmartConsole with full administrator privileges, and modify the security policy or security configuration," Rapid7 said . Successful exploitation requires an attacker to have network access to the Management Server and a configuration that does not restrict Trusted Clients. Check Point has disclosed that it...

Cybersecurity researchers have sounded an alert after finding more than 36,000 Baseboard Management Controller (BMC) management interfaces exposing Intelligent Platform Management Interface (IPMI) protocol to the public internet. Of the 36,872 internet-exposed server-management interfaces running IPMI, 24,650 have been found to disclose password-derived authentication hashes before login due to a vulnerability with the IPMI v2.0 specification itself, according to a new report Lava shared with The Hacker News. IPMI v2.0 was introduced in February 2024. The issue in question is CVE-2013-4786 (CVSS score: 7.5), a high-severity information disclosure flaw that enables remote attackers to obtain password hashes for valid accounts and conduct offline password guessing attacks by obtaining the HMAC from an RMCP+ Authenticated Key-Exchange Protocol (RAKP) message response from a BMC. Per an advisory released by Dell, "this is an inherent problem with the specification for IPMI ...
