Salesforce Hack 2025: What Happened and How to Defend Your CRM

Salesforce powers millions of customer interactions every day, making it one of the most trusted and widely used customer relationship management (CRM) platforms in the world. But with great popularity comes great risk. In 2025, attackers exploited weaknesses not in Salesforce’s core platform, but in its ecosystem of integrations, AI features, and end users.

The recent wave of attacks, ranging from stolen OAuth tokens to AI prompt injection and even voice-based phishing, exposed just how vulnerable CRM systems can be if they’re not carefully secured. For all companies that depend on suppliers like Salesforce to manage sensitive customer and financial data, these incidents should serve as a wake-up call.

In this article, we’ll break down what happened, why it matters, and, most importantly, how your organization can prepare and defend against similar threats.

Network infiltration

What Happened

1. Third-Party Integration Abuse

One of the first attack paths involved OAuth tokens tied to Salesforce integrations such as Drift. By compromising these tokens, attackers were able to run queries against Salesforce without ever needing usernames or passwords.

The impact: Entire data sets, customer records, sales opportunities, account notes, even API keys were quietly exfiltrated. Because the attack used trusted integrations, it often bypassed traditional security controls.

2. AI Prompt Injection (“ForcedLeak”)

Another campaign targeted Salesforce’s Agentforce AI. By poisoning input fields on Salesforce web forms, attackers could slip in hidden instructions that tricked the AI into leaking data to external sites.

The twist: One of the domains Salesforce AI trusted for outbound communication had expired and been re-purchased by attackers for just a few dollars. This gave them a “backdoor” channel to capture sensitive CRM data.

The lesson: AI agents are powerful, but without strict guardrails, they can be manipulated into doing the attacker’s work for them.

3. Social Engineering with Fake Tools

In a separate incident, hackers distributed a modified version of Salesforce Data Loader, a legitimate tool used by admins. Using voice phishing calls (“vishing”), attackers convinced employees to install the fake version. Once deployed, it funneled Salesforce records directly to attacker-controlled servers.

The lesson: Even the best security technologies can’t protect against human error if employees aren’t trained to recognize and resist manipulation.

Why This Matters

Salesforce wasn’t “broken into” in the traditional sense. Instead, attackers exploited trust relationships:

• Integrations – Apps like Drift or middleware often request broad access to Salesforce. One compromise equals full data access.

• AI Agents – Tools like Agentforce can be manipulated if they’re not restricted to safe outputs.

• End Users – Employees remain the softest target through phishing and vishing.

This is dangerous because:

• CRM data is gold – Customer lists, financial notes, credentials, and API tokens are often stored in Salesforce.

• Attackers are patient – They don’t need to hack Salesforce directly; they just need to exploit a weak link.

• Ripple effects are real – A CRM breach doesn’t stop with stolen data. It can cascade into financial fraud, reputational damage, and even regulatory fines.

How to Defend Your Salesforce Environment

Tactical Steps You Can Take Right Now

1. Audit Integrations

   • Review all connected apps.

   • Revoke unused integrations or reduce over-permissive scopes.

   • Confirm vendors can demonstrate their own security controls.

2. Rotate Tokens and Keys

   • Immediately revoke and reissue OAuth tokens for integrations.

   • Rotate API keys and any credentials stored in Salesforce.

3. Strengthen Access Controls

   • Apply the principle of least privilege to all roles.

   • Enforce IP restrictions, session timeouts, and device controls.

4. Require Multi-Factor Authentication (MFA)

   • Ensure MFA is required for every user, including admins and service accounts.

   • Replace weak SMS MFA with app-based push notifications or hardware tokens.

5. Enable Monitoring and Logging

   • Use Salesforce Event Monitoring to track large queries, failed logins, and odd patterns.

   • Integrate with your SIEM (e.g., Splunk, Microsoft Sentinel) for anomaly detection.

6. Restrict AI Agents

   • Limit which URLs Salesforce AI agents can connect to.

   • Sanitize input fields, especially those open to customers (e.g., web-to-lead forms).

   • Introduce human-in-the-loop reviews for sensitive AI tasks.

7. Educate Employees

   • Run phishing and vishing simulations.

   • Teach staff to verify unusual requests through a secondary channel.

   • Make “trust but verify” part of company culture.

Long-Term Strategies for SaaS Security

• Adopt Zero Trust – Don’t assume integrations or agents are safe by default. Continuously verify access.

• Govern AI usage – Apply guardrails, monitor AI outputs, and regularly test for prompt injection vulnerabilities.

• Red-team integrations – Test third-party apps and tools for possible abuse.

• Enforce vendor risk management – Require vendors to meet standards (SOC 2, ISO 27001, CIS benchmarks).

• Maintain response playbooks – Document and rehearse how to respond if Salesforce data is exfiltrated.

Conclusion

The recent Salesforce hacks aren’t just about one platform; they highlight a broader shift in the way attackers operate. Rather than brute-forcing logins or exploiting obvious flaws, they are abusing trusted connections, emerging AI systems, and human behavior.

For businesses, the lesson is clear: securing Salesforce and similar technologies requires more than enabling MFA. It requires auditing every integration, monitoring every transaction, and educating every employee.
