Stop Phishing Attacks with Prosopo
Disrupt the automated layers attackers use to scale phishing — bulk-signup, kit deployment, credential replay. Covers your signup forms and auth API, with a script tag on the form, an edge worker on Cloudflare Workers or AWS Lambda@Edge, or both, to cut phishing infrastructure off at the source.
What is Phishing?
Phishing is a type of cyberattack where attackers impersonate legitimate organizations, services, or individuals to trick users into revealing sensitive information. Common targets include login credentials, payment details, personal identification information, and confidential business data.
Attackers often create fake websites, emails, or forms that mimic real services. Users are tricked into entering information, which is then harvested for malicious purposes, including identity theft, financial fraud, and unauthorized account access.
How Bots Facilitate Phishing Attacks
Bots play a critical role in scaling phishing attacks:
- Automated Distribution: Bots can send phishing emails or messages to thousands or millions of recipients within minutes.
- Credential Harvesting: Automated scripts can capture login details submitted to fake forms and test them against multiple platforms.
- Phishing Kit Deployment: Bots assist in setting up and testing phishing kits, ensuring that fake pages function correctly and evade detection.
- Evading Detection: Sophisticated bots can mimic human interactions, making phishing campaigns harder to detect for traditional security systems.
By automating these processes, attackers can execute phishing campaigns at scale, greatly increasing their effectiveness and potential damage.
How Prosopo Helps Stop Phishing Kits
Phishing is human-targeted, but the scaling infrastructure behind every phishing campaign is automated — bulk-signups, kit deployment, harvested-credential testing. Prosopo disrupts those automation layers:
- How the visitor behaves. Mouse movement, scroll rhythm and typing cadence. Automation repeats itself in ways a person does not, and that holds even when every other detail about the session looks ordinary.
- Where the traffic really comes from. Attackers route through home broadband connections and racks of real phones so each request looks like a separate ordinary visitor. Bot protection recognises those networks even when the individual address has no history.
- Spam Filter on signup endpoints. Disposable inboxes and abusive networks used to bulk-create attacker accounts get rejected at the signup form via the Spam Filter, cutting kit deployment off at the source.
- Detection that moves during the attack. When an operator changes tactics mid-attack, the platform adjusts while it is still happening rather than in a write-up afterwards.
- GDPR-compliant by design. No third-party tracking on auth flows — compliance and security at the same time.
The result: the automated layers attackers rely on to scale phishing get harder to operate, even when the human-targeting side of the attack is unchanged.
What to use
- Spam Filter — reject signups from disposable inboxes and networks associated with phishing infrastructure.
- Procaptcha — protect login and signup forms without adding third-party tracking on your auth flow.
- Invisible CAPTCHA — disrupt automated credential testing without making real users solve a challenge.
