All news with #oauth app abuse tag

🔒 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-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.

🔔 The FBI issued a FLASH advisory linking two threat clusters, UNC6040 and UNC6395, to intrusions of corporate Salesforce environments that resulted in data theft and extortion. Early campaigns relied on social engineering and malicious Data Loader OAuth apps to mass-exfiltrate Accounts and Contacts, while later activity used stolen Salesloft/Drift OAuth and refresh tokens to access support cases and harvest secrets. Multiple large enterprises were impacted and the FBI released IOCs to help organizations detect and mitigate compromise.

⚠️ The FBI released IoCs linking two threat clusters, UNC6040 and UNC6395, to a series of data theft and extortion attacks that targeted organizations' Salesforce environments. UNC6395 exploited compromised OAuth tokens tied to the Salesloft Drift app after a March–June 2025 GitHub breach, prompting Salesloft to isolate Drift and take its AI chatbot offline. UNC6040, active since October 2024, used vishing, a modified Data Loader and custom Python scripts to hijack instances and exfiltrate bulk data, while extortion activity has been associated with actors using the ShinyHunters brand.

🔐 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.

🔒 Researchers disclosed two coordinated campaigns that distribute fake browser extensions via malvertising and counterfeit sites to steal credentials, session tokens, and hijack Meta business accounts. Bitdefender documented ads pushing a fake "Meta Verified" add‑on named SocialMetrics Pro that harvests Facebook session cookies and exfiltrates them to a Telegram bot while also querying ipinfo[.]io for IP data. Cybereason described a separate campaign using counterfeit sites promoting a bogus Madgicx Plus platform and multiple rogue Chrome extensions that request broad site access, capture Google identity data, then pivot to Facebook to facilitate account takeover.

🔒 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.

🔐 Tenable and Qualys reported limited unauthorized access to parts of their Salesforce records after attackers stole OAuth tokens from the Salesloft Drift integration. The incidents exposed support-case subject lines, initial descriptions and basic business contact details, but neither vendor's products or core services were affected. Both firms disabled the Salesloft Drift app, revoked or rotated credentials, and said they are working with Salesforce and investigators to contain the impact.

🔒 Salesloft has moved to take Drift offline after a supply‑chain compromise that resulted in the mass theft of OAuth tokens and unauthorized access to Salesforce data. Multiple large vendors — including Cloudflare, Google Workspace, PagerDuty, Palo Alto Networks, and Tenable — confirmed impact, and activity is attributed to clusters tracked as UNC6395 and GRUB1. The incident underscores how fragile integrations can be and the importance of token hygiene, rapid revocation, and enhanced monitoring to contain downstream exposure.

🔒 This article outlines six browser-based attack techniques—phishing with reverse-proxy AitM kits, ClickFix/FileFix command-injection lures, malicious OAuth grants, rogue extensions, weaponized file downloads, and credential attacks exploiting MFA gaps—that security teams must prioritize in 2025. It explains why the browser has become the primary attack surface as users access hundreds of cloud apps, and why traditional email/network controls and endpoint defenses often miss these threats. The piece argues that effective detection requires real-time browser-level visibility and management across managed and unmanaged apps, highlighting Push Security as a vendor offering such capabilities.

🔒 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.

🔒 Salesloft said it will temporarily take its Drift chatbot service offline after a supply-chain compromise led to the mass theft of OAuth and refresh tokens tied to the Drift AI chat agent. The outage is intended to allow a comprehensive security review and build additional resiliency; Drift chatbot functionality and access will be unavailable during the process. Salesloft is working with cybersecurity partners Mandiant and Coalition while investigators, including Google Threat Intelligence Group, attribute the campaign to UNC6395 and report that more than 700 organizations may be affected.

🔒 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.

🔒 A sophisticated adversary exploited legitimate OAuth tokens issued to Salesloft's Drift chatbot integration with Salesforce, using the connection to silently exfiltrate customer data between August 8–18, 2025, according to Google Threat Intelligence Group. The campaign, attributed to UNC6395, leveraged trust in third-party integrations and service-to-service tokens to maintain covert access. Organizations should reassess OAuth governance, entitlement controls, and logging for SaaS integrations to reduce exposure.

🔒 Palo Alto Networks confirmed a Salesforce data breach after attackers abused OAuth tokens stolen in the Salesloft Drift supply-chain incident to access its CRM. The intruders exfiltrated business contact, account records and support Case data, which in some instances contained sensitive IT details and passwords. Palo Alto says products and services were not affected, tokens were revoked, and credentials rotated.

🔒 Palo Alto Networks confirmed a Salesforce CRM breach after attackers used compromised OAuth tokens from the Salesloft Drift incident to access its instance. The intrusion was limited to Salesforce and exposed business contacts, account records and portions of support cases; technical attachments were not accessed. The company quickly disabled the app, revoked tokens and said Unit 42 found no impact to products or services.

🔐 Palo Alto Networks confirmed last week that a breach of Salesloft’s Drift third‑party application allowed unauthorized access to customer Salesforce data, affecting hundreds of organizations including Palo Alto Networks. We immediately disconnected the vendor integration from our Salesforce environment and directed Unit 42 to lead a comprehensive investigation. The investigation found the incident was isolated to our CRM platform; no Palo Alto Networks products or services were impacted, and exposed data primarily included business contact information, internal sales account records and basic case data. We are proactively contacting a limited set of customers who may have had more sensitive data exposed and have made support available through our customer support channels.

⚠️ Unit 42 observed a campaign that abused the Salesloft Drift integration using compromised OAuth credentials to access and exfiltrate data from customer Salesforce instances. The actor performed large-scale extraction of objects including Account, Contact, Case and Opportunity records and scanned harvested data for credentials. Salesloft revoked tokens and notified affected customers; organizations should immediately review logs, rotate exposed credentials and hunt for the provided IoCs.

🔒 Zscaler has disclosed that OAuth tokens tied to the third-party Salesloft Drift application were stolen, allowing an attacker to access its Salesforce instance. The company said exposed data included business contact details, job titles, phone numbers, regional information, product licensing and some plain-text support case content, but not attachments or images. Zscaler revoked the app's access, rotated API tokens, implemented additional safeguards and urged customers to remain vigilant for phishing and social-engineering attempts.

🔒 Amazon's threat intelligence team identified and disrupted a watering hole campaign conducted by APT29, a group linked to Russia’s SVR. The actor compromised legitimate websites and injected obfuscated JavaScript to redirect a subset of visitors to attacker-controlled pages that mimicked Cloudflare verification. The campaign aimed to abuse Microsoft's device code authentication flow to trick users into authorizing attacker-controlled devices; Amazon isolated affected EC2 instances and coordinated with partners to disrupt infrastructure and share intelligence.
