Salesforce Flags Unauthorized Access via Gainsight OAuth

🔒 Salesforce reported detected 'unusual activity' involving Gainsight-published applications that used OAuth connections to its platform and said the activity may have enabled unauthorized access to some customers' Salesforce data. The company revoked all active access and refresh tokens for affected apps and temporarily removed those listings from the AppExchange while it investigates. Gainsight also pulled its app from the HubSpot Marketplace as a precaution. Security analysts have linked the activity to the ShinyHunters (UNC6240) group and are urging customers to review and revoke suspicious third-party integrations.

Hardening Google Workspace: Practical Guidance for Teams

🔒 Small security teams can harden Google Workspace by enforcing MFA, restricting admin roles, and tightening sharing and OAuth app permissions. The article stresses stronger email defenses — advanced phishing controls, DMARC/DKIM/SPF — and proactive monitoring for account takeovers through alerts and behavioral signals. It argues native controls form a solid foundation but leave gaps, and recommends augmenting them with Material Security for unified visibility and automated remediation.

CoPhish: Microsoft Copilot Studio Agents Steal OAuth Tokens

🔐 Datadog Security Labs has described a new phishing technique called CoPhish that abuses Copilot Studio agents to present fraudulent OAuth consent requests on legitimate Microsoft-hosted demo pages. Attackers can configure an agent’s Login topic to deliver a malicious sign-in button that redirects to a hostile application and exfiltrates session tokens. Microsoft confirmed it will address the underlying causes in a future update and recommends governance and consent hardening to reduce exposure.

ThreatsDay: Widespread Attacks Exploit Trusted Systems

🔒 This ThreatsDay bulletin highlights a series of recent incidents where attackers favored the easiest paths in: tricking users, abusing trusted services, and exploiting stale or misconfigured components. Notable items include a malicious npm package with a post-install backdoor, a CA$176M FINTRAC penalty for missed crypto reporting, session hijacking via MCP (CVE-2025-6515), and OAuth-based persistent backdoors. Practical defenses emphasized are rapid patching, disabling risky install hooks, auditing OAuth apps and advertisers, and hardening agent and deserialization boundaries.

Dreamforce Highlights Salesforce Amid OAuth Security Storm

🛡️ At Dreamforce, Salesforce emphasized shared responsibility for securing customer environments and introduced new AI agents for security and privacy. The conference largely avoided discussion of recent OAuth-based supply-chain breaches that exposed data from hundreds of companies and led to extensive litigation. Analysts warn the incidents — driven by compromised tokens from third-party apps like Salesloft Drift and spoofed tools such as malicious Data Loader instances — underscore systemic risks as AI integrations demand broader data access. Recommended mitigations include IP whitelisting, DPoP or mTLS, and tighter vendor governance.

AgentCore Identity: Secure Identity for AI Agents at Scale

🔐 Amazon Bedrock AgentCore Identity centralizes and secures identities and credentials for AI agents, integrating with existing identity providers such as Amazon Cognito to avoid user migration and rework of authentication flows. It provides a token vault encrypted with AWS KMS, native AWS Secrets Manager support, and orchestrates OAuth 2.0 flows (2LO and 3LO). Declarative SDK annotations and built-in error handling simplify credential injection and refresh workflows, helping teams deploy agentic workloads securely at scale.

Researchers Identify Architectural Flaws in AI Browsers

🔒 A new SquareX Labs report warns that integrating AI assistants into browsers—exemplified by Perplexity’s Comet—introduces architectural security gaps that can enable phishing, prompt injection, malicious downloads and misuse of trusted apps. The researchers flag risks from autonomous agent behavior and limited visibility in SASE and EDR tools. They recommend agentic identity, in-browser DLP, client-side file scanning and extension risk assessments, and urge collaboration among browser vendors, enterprises and security vendors to build protections into these platforms.

Defend the Target, Not Just the Door: Google Workspace

🛡️ Modern cloud work lives across email, files, chat, and a mesh of integrations, and attackers increasingly exploit trusted OAuth grants rather than compromising accounts directly. In early August the actor behind recent Salesforce intrusions used stolen Drift email tokens to access a small set of Google Workspace mailboxes; Google revoked the tokens and disabled the integration on August 9. Material Security advocates shifting from perimeter-only defenses to content-centric controls such as message-level MFA, OAuth governance, and automated containment to make stolen tokens far less damaging.

Trinity of Chaos Launches TOR Data Leak Site, Exposes Data

🔓 The Trinity of Chaos collective has opened a data leak site on the TOR network, publishing previously undisclosed records tied to past breaches and listing 39 major global firms. Resecurity says the group claims more than 1.5 billion records across 760 companies and has set an October 10 negotiation deadline. Samples reportedly contain substantial PII and appear to stem from compromised SaaS environments via stolen OAuth tokens and vishing; the FBI has issued a flash alert. The group also threatened to leverage existing litigation and regulatory complaints against Salesforce, which has denied new vulnerabilities.

Extortion Gang Reveals Alleged Salesforce Victims List

🔓 The Scattered Lapsus$ Hunters gang opened a public data-leak site claiming it stole Salesforce data from dozens of global companies, including Salesforce, Toyota, FedEx, Disney/Hulu, Marriott and Google. The group set an Oct. 10 deadline for ransom payments and threatened to publish or even use stolen documents in legal actions if demands are not met. Salesforce says its investigation found no indication the platform itself was compromised and attributes the incidents to past or unsubstantiated claims. Researchers link many breaches to vishing that installs malicious connected apps and to compromised OAuth tokens in Salesloft Drift, underscoring a broader SaaS supply-chain risk.

ShinyHunters Leak Salesforce Data; Many Companies Exposed

🔓 An extortion group claiming affiliation with ShinyHunters, Scattered Spider, and Lapsus$ has launched a public data leak site listing 39 companies allegedly compromised via Salesforce breaches. The site publishes sample records and urges victims to pay before an October 10 deadline, while also demanding that Salesforce pay to prevent disclosure of roughly 1 billion records. The attackers say they used OAuth-based voice-phishing and stolen tokens to access customer data. Victims named include FedEx, Disney/Hulu, Google, Cisco, and many other major brands.

UNC6040: Proactive Hardening for SaaS and Salesforce

🔒 Google Threat Intelligence Group (GTIG) tracks UNC6040, a financially motivated cluster that uses telephone-based social engineering to compromise SaaS environments, primarily targeting Salesforce. Operators trick users into authorizing malicious connected apps—often a fake Data Loader—to extract large datasets. The guidance prioritizes identity hardening, strict OAuth and API governance, device trust, and targeted logging and SIEM detections to identify rapid exfiltration and cross‑SaaS pivots.

SaaS-to-SaaS Proxy: Centralized Visibility and Control

🌐Cloudflare is prototyping a SaaS-to-SaaS proxy that consolidates SaaS connections through a single front door to improve monitoring, detection, and response. Two deployment models are proposed: a customer-controlled vanity hostname proxy that returns visibility to data owners, and a vendor-side reverse proxy that strengthens platform security. Both approaches use key splitting to avoid persisting full bearer tokens and enable instant revocation. Cloudflare is seeking feedback and offering early access.

Webinar: Securing the Modern Web Edge from Browser Threats

🔒 On September 29 at 12:00 PM ET, BleepingComputer and SC Media will host a live webinar featuring browser security experts from Push Security to examine how modern web browsers have become a primary enterprise attack surface. The session will cover malicious and shadow extensions, session token theft, OAuth abuse, and emerging ClickFix and FileFix techniques, plus mitigation strategies. Attendees will learn practical detection and response approaches to protect SaaS sessions, restore visibility at the web edge, and close gaps missed by traditional endpoint and identity controls.

Browser-Based Attacks: Six Threats Security Teams Must Know

🔒 Browser-targeted attacks are rising as adversaries treat the browser as the primary access point to cloud services and corporate data. The article defines browser-based attacks and enumerates six high-risk techniques: credential and session phishing, ClickFix-style copy-and-paste exploits, malicious OAuth consent flows, rogue extensions, malicious file delivery, and credential reuse where MFA gaps exist. These vectors are effective because modern work happens in decentralized SaaS environments and across many delivery channels, making traditional email- and network-centric defenses less reliable. The piece highlights visibility gaps for security teams and points to vendor platforms such as Push Security that claim to provide in-browser detection and remediation for AiTM phishing, OAuth abuse, and session hijacking.

Token Management Risks in the Third-Party Supply Chain

🔐 This Unit 42 report describes how compromised OAuth tokens in third‑party integrations create severe supply‑chain exposure, using recent incidents as examples. It highlights three recurring weaknesses: dormant integrations, insecure token storage and long‑lived credentials, and explains how attackers exploit these to exfiltrate data and pivot. The authors recommend token posture management, encrypted secret storage and centralized runtime monitoring to detect and revoke abused tokens quickly.

Beaches and Breaches: Shifts in Supply Chain and Identity

🌊 Returning from vacation, the author notes headlines shifted away from AI and ransomware toward breaches tied to compromised OAuth tokens and integrations like Salesloft/Drift. The piece emphasizes two converging trends: supply chain risk that now includes datapaths where information is processed, and identity attacks that increasingly target interconnected applications. It highlights Cisco Talos’ CTI-CMM as a practical maturity framework to assess gaps, prioritize investments, and build a roadmap for continuous improvement.

SalesLoft Drift Breaches Expose Fourth-Party OAuth Risk

🔐 The SalesLoft acquisition of Drift exposed a hidden fourth‑party attack surface when legacy OAuth tokens—some dormant for 18 months—were abused to access customer Salesforce instances and a limited number of Google Workspace accounts. Attackers leveraged inherited tokens to enumerate and exfiltrate data, revealing how M&A can transfer persistent permissions outside visibility. The author calls for continuous, behavior‑based monitoring of every OAuth token and API call and recommends practical "OAuth archaeology" to inventory, rotate, or revoke legacy access.

Salesloft: GitHub Compromise Led to Drift OAuth Theft

🔒 Salesloft confirmed that a threat actor gained access to its GitHub account between March and June 2025, using that access to download repositories, add a guest user and create workflows. The attacker then moved into the Drift app environment, obtained OAuth tokens and used Drift integrations to access customers’ Salesforce instances and exfiltrate secrets. Affected customers include security vendors such as Tenable, Qualys, Palo Alto Networks, Cloudflare and Zscaler. Google Mandiant performed containment, rotated credentials and validated segmentation; the incident is now in forensic review.

Majority of Organizations Hit by Third‑Party Incidents

🔒 A recent survey by SecurityScorecard found 71% of organizations experienced at least one material third‑party cybersecurity incident in the past year, with 5% reporting ten or more. Rising third‑party involvement — echoed in the 2025 Verizon Data Breach Investigations Report — and sprawling supplier ecosystems expand attackers’ avenues. Experts warn SaaS platforms, open‑source packages, and CI/CD pipelines are increasingly exploited, often via abused OAuth, stolen credentials, or over‑permissioned integrations.
