Securing Against Modern Cyber Threats
The landscape of cyber threats is constantly evolving, with threat actors finding new ways to exploit legitimate services for their malicious activities. Instead of relying on traditional attack methods, cybercriminals are now leveraging trusted file hosting services like SharePoint, OneDrive, and Dropbox as part of their defense evasion tactics.
By abusing these widely-used platforms, hackers can compromise identities and devices, leading to devastating consequences such as business email compromise attacks, financial fraud, and data theft. This approach, known as living-off-trusted-sites, allows attackers to blend in with legitimate network traffic, making it harder to detect and attribute their actions.
One of the key techniques utilized in these attacks is the use of phishing emails that contain malicious files hosted on these platforms with restricted access settings. Recipients are prompted to sign in or authenticate their identity to view the contents, only to be redirected to phishing pages that steal their login credentials and two-factor authentication tokens.
To combat these sophisticated threats, organizations must prioritize security awareness training for employees, deploy multi-layered security defenses, and implement strict access controls on file-sharing services. By staying vigilant and proactive in addressing these evolving cybersecurity challenges, businesses can better protect themselves against the growing menace of cyber attacks.
