Hotel Wi-Fi attacks use custom malware to breach Microsoft 365 accounts
August 3, 2026
Back to all postsIn recent news, cybercriminals have been targeting hotel Wi-Fi networks, employing custom malware designed to infiltrate Microsoft 365 accounts. The attacks exploit vulnerabilities in the Windows Print Spooler service and have been successful in compromising a range of sensitive data, including emails, documents, and financial information. These attacks pose a significant threat to Canadian businesses, especially SMBs that rely on cloud-based services like Microsoft 365 for their daily operations. To mitigate this risk, it's crucial for IT managers to regularly update and patch their systems, enable multi-factor authentication (MFA), and ensure the use of strong, unique passwords across all accounts. Furthermore, employee training on cybersecurity best practices can help prevent falls for these types of attacks.
