Summary

Hide ▲

The Salty2FA phishing kit has evolved to incorporate enterprise-grade features, making it difficult to distinguish from legitimate software. The kit's advanced capabilities include subdomain rotation, abuse of legitimate platforms, dynamic corporate branding, MFA mimicry, and sophisticated defense evasion tactics. Ontinue researchers tracked a campaign using Salty2FA, observing its technical innovations and how it mimics legitimate enterprise systems. The campaign impersonated a known business using a trial account on Aha.io and deployed a OneDrive sharing page as the initial attack vector. The kit's infrastructure supports dynamic branding and advanced evasion techniques, making it challenging for security teams to detect and mitigate. The kit's advanced features include geo-blocking, ASN/IP filtering, and JavaScript-based anti-debugging, which hinder the efforts of security researchers and SOC teams. The Salty2FA phishing kit targets industries including finance, energy, healthcare, government, logistics, IT consulting, education, construction, telecom, chemicals, industrial manufacturing, real estate, and consulting. Salty2FA activity began gaining momentum in June 2025, with early traces possibly dating back to March–April 2025. Salty2FA campaigns have been active since late July 2025, generating dozens of fresh analysis sessions daily. The kit uses a multi-stage execution chain, including email lures, redirects to fake login pages, credential theft, and 2FA bypass techniques. Salty2FA employs Cloudflare checks to bypass automated filters and uses fake Microsoft-branded login pages to steal credentials. The kit intercepts push, SMS, and voice-based 2FA codes, leading to account takeovers. ANY.RUN sandbox analysis provides full-chain visibility of Salty2FA attacks, revealing behavioral patterns and reducing analyst workload. Defenders are advised to adopt advanced, layered protection and a behavioral-oriented approach to counter these evolving threats.

SOCs are advised to rely on behavioral detection, detonate suspicious emails in a sandbox, harden MFA policies, train employees on financial lures, and integrate sandbox results into their security stack. Interactive sandboxes like ANY.RUN improve SOC efficiency, speed up investigations, and reduce escalations, providing faster triage and clearer IOCs and TTPs.

UNC6040 and UNC6395 Target Salesforce Platforms in Data Theft Campaigns

The FBI has issued an alert about two cybercriminal groups, UNC6040 and UNC6395, targeting Salesforce platforms for data theft and extortion. UNC6395 exploited compromised OAuth tokens for the Salesloft Drift application, while UNC6040 used vishing campaigns and modified Salesforce tools to breach Salesforce instances. Both groups have been active since at least October 2024, impacting multiple organizations. UNC6040 has been linked to extortion activities, with Google attributing these to a separate cluster, UNC6240, which has claimed to be the ShinyHunters group. The ShinyHunters group, along with Scattered Spider and LAPSUS$, recently announced they are going dark, but experts warn that the threat persists. UNC6040 impersonated corporate IT support personnel to gain access to Salesforce environments and used modified versions of Salesforce's Data Loader to exfiltrate data. Salesforce re-enabled integrations with Salesloft technologies, except for the Drift app, which remains disabled.

Axios and Microsoft Direct Send Abused in Advanced Phishing Campaigns

Threat actors are abusing HTTP client tools like Axios and Microsoft's Direct Send feature to conduct highly efficient phishing campaigns. These attacks target Microsoft 365 environments, achieving a 70% success rate. The campaign began in July 2025, initially focusing on executives and managers in finance, healthcare, and manufacturing sectors before expanding to all users. The attacks use compensation-themed lures and malicious QR codes to steal credentials. Axios is used to intercept, modify, and replay HTTP requests, bypassing multi-factor authentication (MFA) and hijacking session tokens. The phishing kits also employ advanced evasion tactics, including geofencing and IP filtering, to avoid detection. Organizations are advised to secure Direct Send, configure anti-spoofing policies, and train employees to recognize phishing attempts.

Supply Chain Attack on npm Packages with Billions of Weekly Downloads

A supply chain attack compromised multiple npm packages with over 2.6 billion weekly downloads. Attackers injected malicious code into these packages after hijacking a maintainer's account via phishing. The malware targets web-based cryptocurrency transactions, redirecting them to attacker-controlled wallets. The attack was detected and mitigated by the NPM team, who removed the malicious versions within two hours. The phishing campaign targeted multiple maintainers, using a fake domain to trick them into updating their 2FA credentials. The malicious code operates by hooking into JavaScript functions and wallet APIs, intercepting and altering cryptocurrency transactions. The attack impacts users who installed the compromised packages during a specific time window and have vulnerable dependencies. The attack targeted Josh Junon, also known as Qix, who received a phishing email mimicking npm. The phishing email prompted the maintainer to enter their username, password, and 2FA token, which were stolen via an adversary-in-the-middle (AitM) attack. The attack affected 20 packages, including ansi-regex, chalk, debug, and others, with over 2 billion weekly downloads. The malware intercepts cryptocurrency transaction requests by computing the Levenshtein distance to swap the destination wallet address. The payload hooks into window.fetch, XMLHttpRequest, and window.ethereum.request, along with other wallet provider APIs. The attack also compromised another maintainer, duckdb_admin, to distribute the same wallet-drainer malware. The affected packages from the second maintainer include @coveops/abi, @duckdb/duckdb-wasm, and prebid, among others. The attack impacted roughly 10% of all cloud environments. The attackers diverted five cents worth of ETH and $20 worth of a virtually unknown memecoin. The attacker’s wallet addresses holding significant amounts have been flagged, limiting their ability to convert or use the funds.

Salesloft Disables Drift Following OAuth Token Theft

Salesloft has taken Drift offline due to a security incident involving the theft of OAuth tokens and unauthorized access to Salesforce data. The breach began with the compromise of Salesloft's GitHub account, affecting multiple major tech companies, including Cloudflare, Google Workspace, PagerDuty, Palo Alto Networks, Proofpoint, SpyCloud, Tanium, Tenable, Zscaler, Tenable, Qualys, Rubrik, Spycloud, BeyondTrust, CyberArk, Elastic, Dynatrace, Cato Networks, and BugCrowd. The incident was attributed to a threat cluster tracked as UNC6395 and GRUB1. The breach occurred on September 5, 2025, affecting the marketing software-as-a-service product Drift. The attackers exploited vulnerabilities to steal authentication tokens, leading to unauthorized access to sensitive data. Salesloft has temporarily disabled Drift to conduct a comprehensive review and enhance security measures. The ShinyHunters extortion gang and threat actors claiming to be Scattered Spider were involved in the Salesloft Drift attacks, in addition to the previous Salesforce data theft attacks. The threat actors primarily focused on stealing support cases from Salesforce instances, which were then used to harvest credentials, authentication tokens, and other secrets shared in the support tickets. The threat actors' primary objective was to steal credentials, specifically focusing on sensitive information like AWS access keys, passwords, and Snowflake-related access tokens. The number of impacted companies has been updated to 29. Cloudflare disclosed that some customer support cases stored in Salesforce included configuration settings and 104 Cloudflare API tokens. Salesforce restored integration with the Salesloft platform, except for the Drift app, which remains disabled until further notice. The breach also affected Qantas, where executives had their short-term compensation reduced by 15% due to a data breach that impacted approximately 5.7 million passengers.
