BianLian Ransomware Impersonation in Postal Mail Scam

A new wave of scams targeting CEOs across the United States has emerged, utilizing the U.S. Postal Service as a vector. These scams involve fraudulent ransom notes mailed to corporate executives, falsely claiming to be from the BianLian ransomware group. This article explores the details of the scam, its implications, and protective measures against such attacks.

The Mechanics of the Scam

The scam begins with a physical letter sent directly to the CEO’s corporate or personal address. These letters bear the stamp “Time Sensitive Read Immediately” and originate from a seemingly U.S.-based return address, specifically an office building in Boston, Massachusetts. Inside the envelope, the ransom note claims that the BianLian group has compromised the company’s systems and exfiltrated sensitive data, threatening to leak it unless a ransom, typically ranging from $250,000 to $500,000, is paid within ten days. The letters even contain a QR code linked to a Bitcoin wallet for payment, adding a veneer of authenticity to the scheme.

Targets and Demands

While these letters appear to randomly target organizations across various sectors, there seems to be a heavier concentration within the healthcare industry. Intriguingly, the ransom demands for healthcare organizations have consistently been set at $350,000. The scammers also tailor the ransom notes to the target company’s industry, referencing specific data types likely held by each organization. For instance, notes to healthcare companies mention stolen patient and employee data, while those to product-based companies claim they’ve accessed customer orders and employee information.

Distinguishing the Scam from Legitimate BianLian Activity

Several factors indicate that these mailings are a scam and not the work of the actual BianLian ransomware group. The FBI has not found any connections between the senders of the letters and the known BianLian group. The ransom notes themselves deviate significantly from BianLian’s typical communication style. Authentic BianLian ransom notes are known for direct negotiation with victims, whereas these letters offer no avenue for negotiation and impose a strict ten-day payment deadline. The inclusion of the QR code directly in the letter also diverges from BianLian’s usual practice.

Insights and Protective Measures

This BianLian impersonation scam highlights a shift in tactics among cybercriminals. The use of physical mail introduces an element of surprise and potentially increased psychological impact on targets, particularly as letters are sometimes delivered to personal addresses. The relative inefficiency of this method, requiring individual mailings, contrasts with the typical broader reach of online attacks, suggesting a focus on high-value targets. The FBI and cybersecurity experts strongly advise against paying the ransom. This not only fails to guarantee the return of data but also incentivizes further criminal activity.

Protecting Your Organization

To mitigate the risk of falling victim to such scams, organizations should take the following steps:

• Awareness and Education: Inform all employees, especially executives, about this and other similar scams. Educate employees about recognizing and responding to suspicious communications, both online and physical.
• Cybersecurity Hygiene: Implement strong cybersecurity defenses and regularly update systems to patch vulnerabilities. Ensure timely patching and utilize multi-factor authentication wherever possible.
• Incident Response Plan: Develop a clear incident response plan that includes procedures for handling ransomware attacks and other cyber incidents. This plan should outline clear communication channels and steps for containment and recovery.
• Report Suspicious Activity: Report any suspicious communications or suspected cyberattacks to the appropriate authorities, including the FBI and local law enforcement.

The BianLian postal scam underscores the ever-evolving nature of cyber threats and the importance of staying informed and vigilant. By adopting a proactive security posture and educating employees, organizations can better protect themselves against these and other emerging threats.
