Malicious images that are most likely to be blocked typically fall into several categories, including but not limited to:
Phishing Images: These contain embedded links or QR codes that redirect users to fake login pages to steal credentials. For example, an image in an email might appear as a legitimate login button but hides a malicious URL.
Malware-Delivery Images: Some images are crafted to exploit vulnerabilities in image-rendering libraries (e.g., steganography-based attacks where malware is hidden within the image file).
Scam or Fraud Images: Images used in scams, such as fake prize notifications, fake invoices, or counterfeit product advertisements, are often blocked.
Hate Speech or Violent Content: Images promoting violence, terrorism, or hate speech are flagged by content moderation systems.
Adult or Explicit Content: Pornographic or sexually explicit images are typically blocked by platforms to comply with regulations.
Copyright-Infringing Images: Images used without proper licensing or ownership rights may be blocked by automated systems.
Example: A user uploads an image to a social media platform that contains a hidden phishing link. The platform’s AI-driven security system detects the suspicious URL embedded in the image and blocks it before it can be shared.
For businesses needing robust image security, Tencent Cloud offers services like Content Security (Image Moderation), which uses AI to detect and block malicious or inappropriate images in real time. This helps prevent phishing, scams, and other threats.
