🚨 Immediate Action Required

On September 12, 2025, the FBI issued FLASH alert FLASH-20250912-001 warning about two cybercriminal groups actively targeting Salesforce platforms. Major companies including Google, Chanel, Qantas, and Allianz have already been compromised. Your organization could be next.

The Threat Landscape Has Changed

In 2025, cybercriminals have evolved beyond traditional network breaches. They’re now targeting the very features that make Salesforce powerful—its integrations and ease of use. Two sophisticated threat groups, UNC6040 and UNC6395, have developed methods that bypass traditional security controls including MFA, making them extremely dangerous.

What makes these attacks so concerning:

• They use legitimate authentication mechanisms (OAuth tokens)
• They bypass MFA and login monitoring
• The activity appears to come from trusted integrations
• No vulnerabilities in Salesforce itself are exploited
• They target the human element through sophisticated social engineering

How These Attacks Work

The diagram shows the complete attack flow from initial contact to data exfiltration

🎯 UNC6040: Voice Phishing (Vishing)

1. Initial Contact: Attackers call help desk posing as IT support
2. Social Engineering: Claim to resolve “enterprise-wide connectivity issues”
3. Deception: Guide employees to authorize malicious connected apps
4. Persistence: Modified Salesforce Data Loader grants ongoing access
5. Exfiltration: Bulk data extraction via API queries
6. Extortion: ShinyHunters demands cryptocurrency payments

🔗 UNC6395: OAuth Token Compromise

1. Supply Chain Attack: Compromise Salesloft’s GitHub (March-June 2025)
2. Token Theft: Extract OAuth tokens from AWS Drift instance
3. Direct Access: Use stolen tokens to authenticate to Salesforce
4. Data Mining: Target support cases for credentials and tokens
5. Lateral Movement: Use harvested credentials to access other cloud services
6. Scale Impact: Pivot to multiple cloud environments

FBI Indicators of Compromise

The FBI has released specific technical indicators to help organizations detect these attacks:

🔍 Key IOCs to Monitor:

• Suspicious User-Agent Strings: “Salesforce-Multi-Org-Fetcher/1.0”, “python-requests/2.32.4”
• Malicious URLs: login.salesforce.com/setup/connect with suspicious user codes
• IP Addresses: Over 70 known malicious IPs in the FBI alert
• Unusual API Activity: Bulk data queries from connected apps
• New OAuth Apps: Especially modified Data Loader applications
