In March 2024, a threat actor bypassed a major healthcare provider's two-factor authentication by intercepting SMS codes through a SIM-swapping attack — compromising over 2 million patient records. The organization thought they were protected. They had "MFA" checked off on their compliance audit. But they'd
In February 2024, a threat actor compromised a single employee's account at Change Healthcare, triggering the largest healthcare data breach in U.S. history — affecting roughly 100 million people. The entry point? An account that lacked multi-factor authentication entirely. UnitedHealth Group CEO Andrew Witty confirmed this during congressional
In March 2022, Lapsus$ breached Okta, Microsoft, and Nvidia — three companies with enormous security budgets — partly by exploiting weak or absent multi-factor authentication. The attackers used social engineering, SIM swapping, and MFA fatigue attacks to bypass single-layer defenses. Had stronger two-factor authentication been uniformly enforced, several of those breaches could
In February 2022, a teenage hacker tricked a T-Mobile employee into performing a SIM swap, then used that hijacked phone number to intercept SMS verification codes and breach Lapsus$ targets including Nvidia and Microsoft. The attack wasn't sophisticated. It didn't require zero-day exploits. The threat actor
In March 2020, Microsoft engineers published a finding that stunned even seasoned security professionals: accounts protected by multi-factor authentication block over 99.9% of automated attacks. Yet as of mid-2021, adoption remains shockingly low. The FBI's 2020 IC3 report documented $4.2 billion in cybercrime losses, with compromised
In February 2021, T-Mobile disclosed a data breach that exposed customer phone numbers and SIM information. That same month, the FBI's Internet Crime Complaint Center continued logging a surge in SIM swap complaints — a threat that directly undermines SMS-based two-factor authentication. If your organization still relies on text
In July 2020, a teenager orchestrated one of the most high-profile breaches in social media history — the Twitter hack that compromised accounts belonging to Barack Obama, Elon Musk, and Apple. The attack vector? Social engineering and credential theft that bypassed weak authentication controls. It was a brutal reminder that passwords
Microsoft's security team reported that accounts protected by multi-factor authentication block over 99.9% of automated attacks. Yet according to the FBI's Internet Crime Complaint Center (IC3), credential theft and account compromise remain among the top reported cybercrime categories year after year. The gap between what
In February 2024, a threat actor compromised a single employee's SMS-based multi-factor authentication at a major financial services firm. The method? A SIM swap that took under ten minutes. The attacker intercepted the one-time passcode, drained customer accounts, and left the company facing regulatory action. This wasn'
In September 2023, MGM Resorts lost roughly $100 million after a threat actor called Scattered Spider bypassed the company's authentication controls using a simple social engineering phone call. The attackers didn't crack a password vault or exploit a zero-day. They convinced a help desk employee to
