FBI Notice Spike in Compromised Government Emails Conducting Fake EDRs
INTRODUCTION
In early November, the Federal Bureau of Investigation (FBI) issued a warning regarding the abuse of compromised email accounts from U.S. and foreign government entities. These compromised accounts are being exploited to execute fraudulent Emergency Data Requests (EDRs) aimed at U.S.-based service providers.
WHAT IS AN EDR?
An EDR is a legal mechanism enabling U.S. law enforcement agencies to urgently request confidential data from service providers without a subpoena. Threat actors would take advantage of the procedure by using compromised government email addresses to submit fraudulent EDRs and obtain customer data.
For example, Verizon disclosed that it received over 127,000 law enforcement requests for customer data during the second half of 2023, with more than 36,000 classified as EDRs. The company reported fulfilling approximately 90% of these requests.
HOW DO THREAT ACTORS EXECUTE THESE SCHEMES?
Investigations into cybercrime forums reveal multiple methods used by threat actors to submit fraudulent EDRs. Some fake EDR vendors sell the capability to generate fake EDRs by targeting specific platforms, complete with counterfeit court documents. Other fake EDR vendors simply sell access to compromised government or law enforcement email accounts.
Key tactics used to compromise government or law enforcement email accounts include:
- Phishing and malware campaigns targeting email users.
- Purchase of stolen credentials from dark web marketplaces.
- Exploitation of poor cyber practices among government employees.
KEY LESSONS
The notice serves as a reminder of the dangers posed by the sophistication of scams threat actors can orchestrate once they have access to compromised credentials.
To mitigate risks, organizations and individuals must prioritize cybersecurity hygiene:
- Establish a procedure on handling sensitive emails to avoid getting phished; approach urgent emails or emails with attachments with caution.
- Employ unique and strong passwords for every account and use multi-factor authentication when possible. Data breaches happen often, and threat actors like to take the compromised credentials from these breaches to re-use on other websites.

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.
