Credential Stuffing
An automated attack where stolen username-password pairs from one data breach are systematically tried against other websites, exploiting password reuse.
Credential stuffing exploits a simple human habit: reusing the same password across multiple sites. When a data breach exposes millions of email-password combinations, attackers use automated tools to try those same credentials on banking sites, email services, e-commerce platforms, and social media accounts. If you use the same password for your email and your online banking, a breach at an unrelated service could compromise your bank account.
Why Malaysians Are Vulnerable
With the proliferation of online services — Maybank2u, Shopee, Grab, TNG eWallet — many Malaysians reuse passwords across platforms. Use a unique password for every account and enable two-factor authentication, especially on banking and email.
