BMO Scam Highlighting Vulnerabilities in Two-Factor Authentication
Introduction
A recent article published by CBC news highlighted a concerning scam that involved the Bank of Montreal (BMO). The scam managed to exploit vulnerabilities associated with the two-factor authentication (2FA) system of the bank. This advisory aims to provide an overview of the issue, its implications, and recommendations.
Summary of the Incident
The scam primarily targeted customers with lines of credit. Perpetrators pose as bank employees and use a combination of phishing techniques and flaws in the 2FA process to gain unauthorized access to customers’ accounts, subsequently making unauthorized transactions.
Implications
- The trustworthiness of 2FA is at stake. Customers generally perceive 2FA as a robust security measure, but this incident underscores potential vulnerabilities.
- The scam demonstrates that even with the second layer of authentication, user accounts can be compromised if the process isn’t foolproof.
- Potential loss of customer trust in banking institutions due to such vulnerabilities.
Recommendations
- Stay Informed: Regularly update oneself about the latest scams and phishing techniques. Always be skeptical of unsolicited calls or emails asking for personal or banking information.
- Use Advanced Security Features: Wherever possible, use advanced security features like biometric authentication or hardware-based security keys.
- Monitor Accounts: Regularly check bank accounts for unauthorized transactions and report any discrepancies immediately.
- Stay Educated: Participate in security awareness sessions provided by your Richter Guardian team, the bank or other trusted organizations.
How Richter Guardian can help you
While 2FA is an essential security feature, it is not infallible. Richter Guardian clients should be proactive in understanding its limitations and continuously seek ways to enhance their security posture.

Toyota Confirms Ransomware Attack, Data Breach
Introduction
Toyota Finance Services (TFS), a subsidiary of the well-known automaker, has confirmed that they were hit with a ransomware attack. TFS detected unauthorized access to some of its systems in Africa and Europe after cybercriminals claimed an attack on the company. The cybercriminals, also known as the Medusa ransomware gang, claims responsibility for the attack.
Summary Of the Incident
The Medusa ransomware gang had listed ‘Toyota Financial Services’ to its data leak site on the dark web and demanded a ransom payment of $8,000,000 to delete allegedly stolen data. The cybercriminals published sample data that included financial documents, hashed account passwords, passport scans, etc. to prove the intrusion. As of right now, the incident is limited to Toyota Financial Services Africa & Europe. A spokesperson announced that the process of bringing their systems back online is already underway.
How to Stay Safe
- Reset All Passwords – If you are reusing passwords across different websites, reset those passwords and employ hard-to-guess, complex passwords on those websites.
- Password Manager – To keep track of your complicated passwords, think about investing in a password manager. Password managers, like 1Password, place a secret key on your password manager to add a unique extra layer of security.

Using AI Tools Securely: ChatGPT, Gemini, and More
INTRODUCTION
AI-powered tools are now integrated into various platforms, from office software and operating systems to image editors and chat applications. But how can you use ChatGPT, Gemini, DeepSeek, and other AI-powered tools without compromising your digital security?
AVOID SHARING SENSITIVE INFORMATION WITH AI CHATBOTS
OpenAI’s privacy policy indicates that user data may be utilized to enhance AI performance. When using services like ChatGPT, Sora, or Operator, your interactions could be used to train AI models.
According to a study done by Harmonic Security, 8.5% of prompts contained sensitive information.
Never input sensitive personal information such as passwords, passport or banking details, addresses, phone numbers, names, or any confidential business data. If necessary, replace sensitive details with placeholders like asterisks or “REDACTED.”
For professionals, especially software engineers leveraging AI for code review, it’s crucial to strip out any information that could reveal company secrets and/or application structure.
Everything shared with an AI chatbot has the potential to be stored and analyzed.
FREE AI SERVICES COME WITH HIGHER RISKS
Many free-tier AI tools explicitly state that they train on user data. Organizations using AI should consider investing in paid AI services like ChatGPT Enterprise, which ensures that user inputs and outputs are not utilized for training purposes.
Experts recommend paid plans as a more secure option for businesses looking to mitigate risks.
BEST PRACTICES FOR SAFE AI USE IN THE WORKPLACE
For businesses looking to integrate generative AI tools while minimizing security risks, Harmonic Security suggests shifting away from outright bans and instead implementing effective AI governance strategies. These include:
- Establishing clear AI usage policies and enforcing workflows.
- Monitoring AI tool usage in real time to track inputs and ensure compliance.
- Restricting the use of free AI tools that train on input.
- Classifying sensitive data to prevent exposure.
- Educating employees on responsible AI use and associated risks.
