⚠️ A bug in a dashboard React useEffect dependency caused an object to be recreated on every render, triggering repeated calls to the Tenant Service /organizations endpoint. Those excessive requests coincided with a Tenant Service deployment, overwhelming the service and breaking API authorization checks so many API requests returned 5xx errors and the Cloudflare dashboard became unavailable. Cloudflare mitigated the incident by scaling pods, applying a global rate limit, reverting a problematic patch, and applying a dashboard hotfix. They plan to prioritize Argo Rollouts for safer deployments, add randomized retry delays, increase Tenant Service capacity, and improve observability.

🔐 Okta has uncovered VoidProxy, a phishing-as-a-service operation that uses Adversary-in-the-Middle techniques to harvest Microsoft and Google credentials, MFA codes, and session tokens. The platform leverages compromised ESP accounts, URL shorteners, multiple redirects, Cloudflare Captcha and Cloudflare Workers to evade detection and hide infrastructure. Victims who enter credentials are proxied through an AitM server that captures session cookies and MFA responses, enabling account takeover. Okta recommends passkeys, security keys, device management, and session binding to mitigate the threat.

⚠️ Researchers have exposed a Salty2FA phishing kit that applies enterprise-grade tactics to harvest credentials and bypass detection. The campaign uses session-based subdomain rotation, abuse of legitimate platforms for staging, and corporate-branded login replicas to increase believability. Operators integrate Cloudflare Turnstile and obfuscated, XOR-encrypted JavaScript to block automated analysis and frustrate forensic inspection. Targets include healthcare, finance, technology, energy and automotive sectors, underscoring the need for updated defenses beyond traditional indicators.

🔐 A newly uncovered phishing campaign uses the Salty2FA phishing‑as‑a‑service kit to bypass multi‑factor authentication by intercepting verification methods, rotating unique subdomains and hiding behind Cloudflare Turnstile gates that filter automated analysis. Ontinue found the kit simulates SMS, authenticator apps, push prompts and hardware tokens while dynamically applying corporate branding to match victims' email domains. Industry experts characterize this as a more mature, evasive form of phishing and recommend phishing‑resistant authentication, runtime inspection and continuous user training.

🚀 Cloudflare has added support for the node:http client and server APIs in Workers, enabling developers to deploy existing Node.js HTTP applications at the edge with minimal code changes. This change makes frameworks like Express and Koa runnable on Workers with zero cold starts, automatic scaling, and reduced latency for global users. The client APIs are implemented on top of Workers' native fetch(), and server integration uses an internal bridge that registers listen(port) rather than binding TCP sockets. Some Node-specific features remain limited or unsupported (the Agent is effectively a no-op; trailers, early hints, 1xx responses, and TLS-specific options are not available).

🔒 Palo Alto Networks, Zscaler and Cloudflare disclosed a supply-chain breach traced to the Salesloft Drift integration with Salesforce. The compromise exposed business contact information, account/contact/case/opportunity records and, in some instances, OAuth tokens and plaintext support-case content; attachments and files were reportedly not affected. Palo Alto's Unit 42 observed active searches of exfiltrated data and deletion of queries consistent with anti-forensics. Vendors are advising immediate token revocation, credential rotation and comprehensive review of Salesforce logs and SOQL query history.

🔒 Cloudflare reported that Fina CA issued twelve unauthorized TLS certificates for the public DNS IP 1.1.1.1 between February 2024 and August 2025. All certificates have been revoked and Cloudflare found no evidence they were used maliciously, noting that successful impersonation would also require client trust in Fina and interception of traffic. The misissuance was detected via Certificate Transparency logs, and Cloudflare is improving alerts, monitoring, and triage to prevent similar lapses.

🔒 Cloudflare framed AI Week 2025 around products and controls to help organizations adopt AI while retaining safety and visibility. The company emphasized four core priorities: securing AI environments and workflows; protecting original content from misuse; enabling developers to build secure AI experiences; and applying AI to improve Cloudflare’s services. Key launches included AI Gateway, Infire, AI Crawl Control, expanded CASB scanning, and MCP Server Portals, with a continued focus on customer feedback and ongoing investment.

🔒 Cloudflare and Palo Alto Networks disclosed that threat actors accessed their Salesforce tenants via the third‑party Salesloft Drift app after compromising OAuth tokens. Cloudflare reported reconnaissance on 9 August 2025 and said data was exfiltrated from Salesforce case objects between 12–17 August 2025. The exposed fields principally contained support case text and business contact information; Cloudflare identified 104 API tokens and has rotated them, urging customers to rotate any credentials shared in cases. Google’s Threat Intelligence Group links the activity to UNC6395 and warns harvested data may be used for targeted follow‑on attacks.

🛡️ Cloudflare said it automatically mitigated a record-setting volumetric DDoS attack that peaked at 11.5 Tbps and reached 5.1 billion packets per second; the UDP flood lasted roughly 35 seconds and reportedly originated largely from Google Cloud. The company reported it has autonomously blocked hundreds of hyper‑volumetric L3/4 attacks in recent weeks, underscoring a sharp surge in such events. Security researchers warn these massive traffic floods can be used as a smoke screen for follow-on targeted exploits.

🔒 Three major vendors—Palo Alto Networks, Zscaler, and Cloudflare disclosed a supply‑chain breach tied to the Salesloft Drift Salesforce integration that exposed OAuth tokens and customer CRM data. The incident reportedly involved mass exfiltration from Account, Contact, Case and Opportunity records and included business contact data and some plaintext case notes. Vendors recommend rotating credentials, revoking unused OAuth tokens, auditing Salesforce Event Monitoring and reviewing SOQL query logs and connected-app activity for signs of abuse.

🔒 Cloudflare disclosed attackers accessed a Salesforce instance used for internal customer case management in a broader Salesloft Drift supply‑chain breach, exposing 104 Cloudflare API tokens and the text contents of support case objects. Cloudflare was notified on August 23, rotated all exfiltrated platform-issued tokens, and began notifying impacted customers on September 2. The company said only text fields were stolen — subject lines, case bodies and contact details — but warned customers that any credentials shared via support tickets should be considered compromised and rotated immediately.

🛡️ Cloudflare says it blocked the largest recorded volumetric DDoS attack, peaking at 11.5 Tbps. The UDP flood, which Cloudflare attributes mainly to traffic originating from Google Cloud, lasted roughly 35 seconds and was part of a broader surge of hyper‑volumetric events. The mitigation highlights Cloudflare's automated scaling and defensive capabilities against short, extremely high‑bandwidth assaults.

🔒 Amazon disrupted an operation attributed to the Russian state-sponsored group APT29 that used watering-hole compromises to target Microsoft 365 accounts. The attackers injected obfuscated JavaScript into legitimate sites to redirect roughly 10% of visitors to fake Cloudflare verification pages and then into a malicious Microsoft device code authentication flow. Amazon isolated attacker EC2 instances and worked with Cloudflare and Microsoft to take down identified domains; the campaign did not affect Amazon's infrastructure.

🔍 Cloudflare has integrated Cloudy, its first AI agent, with security analytics and introduced a conversational chat interface to accelerate root-cause analysis and mitigation. The chat lets users ask natural-language questions, refine investigations, and pivot from a single indicator to related threat events in minutes. Paired with the Cloudforce One Threat Events platform and built on the Agents SDK running on Workers AI, Cloudy surfaces contextual IOCs, attacker timelines, and prioritized actions at scale. Cloudflare emphasizes Cloudy was not trained on customer data and plans deeper WAF debugging and Alerts integrations.

🛡️Cloudflare extended its AI agent Cloudy to generate clear, concise explanations for email security detections so SOC teams can understand why messages are blocked. Early LLM implementations produced dangerous hallucinations when asked to interpret complex, multi-model signals, so Cloudflare implemented a Retrieval-Augmented Generation approach and enriched contextual prompts to ground outputs. Testing shows these guardrails yield more reliable summaries, and a controlled beta will validate performance before wider rollout.

🔍 Cloudflare is introducing two AI-powered tools to simplify troubleshooting for the Cloudflare One SASE platform: the new WARP diagnostic analyzer in the Zero Trust dashboard and a DEX MCP server for Digital Experience Monitoring. Both features are available to all Cloudflare One customers by default and convert diagnostic logs into clear, actionable insights. The WARP analyzer highlights events, device details, and exports JSON for deeper analysis, while the DEX MCP server enables natural-language queries and custom analytics without heavy SIEM integration.

🤖 Cloudflare's mid‑2025 dataset shows AI training crawlers now account for nearly 80% of AI bot activity, driving a surge in crawling while sending far fewer human referrals. Google referrals to news sites fell sharply in March–April 2025 as AI Overviews and Gemini upgrades reduced click-throughs. OpenAI’s GPTBot and Anthropic’s ClaudeBot increased crawling share while ByteDance’s Bytespider declined. The resulting crawl-to-refer imbalance — tens of thousands of crawls per human click for some platforms — threatens publisher revenue.

🔊 Cloudflare announced new realtime voice AI capabilities to simplify building low-latency conversational agents on its global edge. The release includes Realtime Agents, a composable runtime for orchestrating STT, LLM, and TTS pipelines at the edge, plus the ability to pipe raw WebRTC audio as PCM into Workers, WebSocket-based realtime inference in Workers AI, and Deepgram models deployed across 330+ cities. These features aim to reduce infrastructure complexity and latency for voice-enabled applications.

🔍 Cloudflare Radar introduces industry-focused AI crawler insights and a new crawl purpose selector that classifies bots as Training, Search, User action, or Undeclared. The update surfaces top bot trends, crawl-to-refer ratios, and per-industry views so publishers can see who crawls their content and why. Data shows Training drives nearly 80% of crawl requests, while User action and Undeclared exhibit smaller, cyclical patterns.
