The relationship between Business Email Compromise (BEC) and threat intelligence. Threat intelligence plays a vital role in preventing and mitigating BEC attacks. Here's how:
- Understanding Attacker Tactics, Techniques, and Procedures (TTPs): Threat intelligence provides insights into the TTPs used by BEC attackers. This includes the types of phishing emails they send, the language they use, the impersonation techniques they employ, and the infrastructure they leverage. By understanding these TTPs, organizations can better prepare their defenses.
- Identifying Indicators of Compromise (IOCs): Threat intelligence can reveal IOCs associated with BEC attacks, such as malicious email addresses, domains, IP addresses, and file hashes. These IOCs can be used to proactively block or flag suspicious activity.
- Predictive Analysis: By analyzing threat intelligence data, organizations can identify emerging BEC trends and predict potential attacks. This allows them to take proactive measures to strengthen their defenses before an attack occurs.
- Real-time Alerts: Threat intelligence feeds can provide real-time alerts about active BEC campaigns, allowing organizations to quickly respond and prevent potential damage.
- Vulnerability Management: Threat intelligence can highlight vulnerabilities that are commonly exploited by BEC attackers, enabling organizations to prioritize patching and remediation efforts.
- Incident Response: During a BEC incident, threat intelligence can help investigators understand the attacker's motives, identify the scope of the attack, and attribute the attack to a specific threat actor.
- Email Filtering: Threat intelligence feeds can be integrated with email security solutions to block emails from known malicious senders and domains.
- Security Information and Event Management (SIEM): SIEM systems can use threat intelligence data to correlate security events and identify suspicious patterns that may indicate a BEC attack.
- Endpoint Protection: Endpoint security solutions can leverage threat intelligence to detect and block malicious files and processes associated with BEC attacks.
- Security Awareness Training: Threat intelligence can inform security awareness training programs, educating employees about the latest BEC tactics and how to identify suspicious emails.
In short: Threat intelligence provides valuable information that helps organizations understand the BEC threat landscape, proactively defend against attacks, and respond effectively to incidents. It's a critical component of a comprehensive BEC defense strategy.
Making staff vigilant against Business Email Compromise (BEC)
Making staff vigilant against Business Email Compromise (BEC) attacks requires a multi-pronged approach involving training, awareness, and clear procedures. Here's a breakdown:
1. Comprehensive Training:
- Phishing Simulations: Regularly conduct realistic phishing simulations to test employees' ability to identify suspicious emails. These simulations should mimic real-world BEC tactics, including impersonation, urgent requests, and emotional manipulation.
- BEC-Specific Training: Dedicate training specifically to BEC attacks, explaining how they differ from traditional phishing. Focus on the common tactics used in BEC, such as:
- Impersonation: Emphasize how attackers impersonate executives, vendors, or other trusted individuals.
- Urgency and Pressure: Explain how attackers create a sense of urgency to bypass verification procedures.
- Emotional Manipulation: Discuss how attackers use emotional appeals (e.g., fear, helpfulness) to trick employees.
- Unusual Requests: Highlight the types of unusual requests commonly made in BEC attacks (e.g., wire transfers, gift card purchases, sensitive data sharing).
- Real-World Examples: Use real-world examples of BEC attacks to illustrate the potential consequences and how easily even experienced employees can be tricked.
- Regular Refreshers: Reinforce training with regular refreshers and updates to keep employees informed about the latest BEC tactics.
2. Awareness and Communication:
- Security Awareness Campaigns: Conduct regular security awareness campaigns to keep BEC top-of-mind. Use posters, newsletters, intranet articles, and other communication channels to reinforce key messages.
- Open Communication: Encourage employees to report any suspicious emails or requests, even if they are unsure. Create a culture where employees feel comfortable asking questions without fear of reprisal.
- Stay Informed: Keep employees informed about the latest BEC trends and tactics through regular updates and alerts.
3. Clear Procedures and Protocols:
- Verification Procedures: Establish clear procedures for verifying requests for wire transfers or sensitive information. This should include:
- Multiple Channels: Verifying requests through multiple channels (e.g., phone call, in-person conversation).
- Known Contact Information: Using known contact information for verification, not the information provided in the email.
- Independent Confirmation: Requiring independent confirmation of requests from a second authorized individual.
- Reporting Mechanisms: Make it easy for employees to report suspicious emails or requests. Provide clear instructions and contact information for the IT or security team.
- No-Pressure Policy: Implement a "no-pressure" policy that empowers employees to question or delay any request that seems suspicious, regardless of who it is supposedly from.
4. Technology and Tools:
- Email Filtering and Anti-Phishing: Implement strong email filtering and anti-phishing solutions to block known malicious emails and flag suspicious messages.
- Multi-Factor Authentication (MFA): Implement MFA for all email and financial accounts to add an extra layer of security.
- Security Information and Event Management (SIEM): Use SIEM systems to detect and correlate suspicious activity that may indicate a BEC attack.
5. Culture of Security:
- Lead from the Top: Ensure that senior management actively promotes a culture of security awareness and vigilance.

By implementing these strategies, organizations can significantly improve their staff's vigilance against BEC attacks and create a stronger line of defense against this sophisticated cyber threat.
How to identify the phishing email?
Let's walk through a few examples of phishing emails, highlighting the red flags that can help you identify them. Remember, attackers are constantly evolving their tactics, so staying vigilant is key.
Example 1: The "Urgent Account Update" Phish
Subject: ACTION REQUIRED: Your Account Will Be Suspended
Email Body:
Dear Valued Customer,
We have detected suspicious activity on your account. To ensure your security, please verify your account details immediately by clicking on the link below:
[malicious link]
Failure to verify your account within 24 hours will result in suspension.
Sincerely,
Your Bank/Service Provider
Red Flags:
- Sense of Urgency: Phrases like "ACTION REQUIRED" and "within 24 hours" are classic phishing tactics designed to pressure you into acting without thinking.
- Generic Greeting: "Dear Valued Customer" is impersonal. Legitimate companies usually address you by name.
- Suspicious Link: Hover over the link without clicking to see the actual URL. It's likely to be different from the legitimate website address. Look for misspellings, unusual characters, or shortened URLs.
- Poor Grammar/Spelling: Phishing emails often contain grammatical errors and typos.
- Threat of Suspension: Legitimate companies rarely threaten account suspension without prior communication.
Example 2: The "Package Delivery" Phish
Subject: Your Package is Arriving Soon!
Email Body:
Dear [Your Name],
Your package is scheduled for delivery tomorrow. Please confirm your delivery address by clicking on the link below:
[malicious link]
Tracking Number: [fake tracking number]
Thank you,
[Fake Delivery Service Name]
Red Flags:
- Unexpected Email: Did you order a package recently? If not, be suspicious.
- Generic Tracking Number: Try entering the tracking number on the legitimate delivery service website. It will likely be invalid.
- Link to Unknown Site: Hover over the link without clicking to see the actual URL. It's likely to lead to a fake website designed to steal your information.
Example 3: The "IT Support" Phish
Subject: Urgent System Maintenance
Email Body:
Dear [Your Name],

[malicious link]
IT Support
Red Flags:
- Unusual Time: IT maintenance is rarely scheduled for peak hours.
- Request for Credentials: IT support will never ask for your password via email.
- Generic Warning: Vague warnings about "disruption" are often used to create a sense of urgency.
Example 4: The "CEO" Phish (BEC)
Subject: Urgent Request
Email Body:
[Employee Name],
I need you to urgently transfer $10,000 to the account below. I'm in a meeting right now and can't discuss it further. Please confirm once the transfer is complete.
Account Details:
[Fake account details]
Thanks,
[Fake CEO Name]
Red Flags:
- Unusual Request: Sudden requests for large sums of money, especially outside of normal procedures, should be treated with suspicion.
- Pressure to Act Quickly: The "I'm in a meeting" excuse is a common tactic to prevent verification.
- Lack of Detail: The email is vague about the reason for the transfer.
- Out-of-Character Communication: Does the email sound like it's really from your CEO? Consider their typical communication style.
General Tips for Identifying Phishing Emails:
- Don't Trust the Display Name: Attackers can easily spoof the "From" address. Always check the actual email address.
- Be Wary of Links: Hover over links before clicking to see the actual URL. Avoid clicking on links in emails from unknown senders.
