ScamLens: The End of Crypto Image Spam on Discord
A major spam wave linked to the "crypto images" scam has led us to activate the Deletion mode of RaidProtect ScamLens, our anti-scam image analysis module, ahead of schedule.
🛡️ Spam details
Two massive spam waves occurred on , between and . Over 2,500 compromised accounts were used to send more than 10,000 messages containing this type of image. These figures only represent what was observed across the 340,000 servers protected by RaidProtect — with Discord having several million active servers, the actual scale of this attack can be estimated at several hundred thousand messages across the platform.
The scam, known as "crypto images", involves mass-sending 4 images urging users to buy fraudulent cryptocurrencies, in as many channels as possible.
Wave 1
Wave 2
Given the high volume of fraudulent messages, we activated the Deletion mode of ScamLens ahead of schedule — initially introduced in Learning mode in update 3.3.1.
This module analyzes images sent on your servers and now automatically deletes those identified as fraudulent (no configuration needed).
What's next?
The Sanction mode will be activated soon: in addition to deleting fraudulent images, ScamLens will automatically apply a one-day timeout to the sender. We chose not to ban these accounts, as they are almost exclusively hacked accounts — a ban would penalize the actual account owner. The timeout neutralizes the threat immediately, giving the owner time to regain control of their account.
For security reasons, we do not and will not disclose the detection methods used by ScamLens. This "black box" approach is designed to prevent scammers from adapting their techniques to bypass our protections.
