In March 2024, a threat actor used a simple brute force attack to compromise a Roku employee's credentials, ultimately exposing over 576,000 customer accounts. No zero-day exploit. No sophisticated malware. Just automated password guessing against accounts with weak credentials and no multi-factor authentication. Brute force attack prevention
In March 2024, a Cisco advisory revealed that a massive brute force campaign was targeting VPN devices, SSH services, and web application portals worldwide — using roughly 28,000 unique IP addresses. The attackers weren't sophisticated. They didn't need to be. They just hammered login pages with
In December 2024, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory warning that Russian military-linked threat actors were systematically using brute force attacks to compromise Microsoft 365 accounts across government agencies and critical infrastructure. These weren't sophisticated zero-day exploits. They were automated password-guessing scripts
In March 2023, the FBI and CISA issued a joint advisory warning that threat actors were actively using brute force techniques to compromise healthcare and public health sector organizations. These weren't sophisticated zero-day exploits. They were automated scripts guessing passwords — millions of combinations per minute — until one worked.
In March 2021, Microsoft disclosed that the Hafnium threat actor group had exploited Exchange Server vulnerabilities — but what most people missed is that many of those compromised servers were initially discovered through brute force password spraying. The attackers didn't need a sophisticated zero-day for every target. They just
A 22-Character Password Cracked in Under 4 Hours In 2023, a security researcher demonstrated that a 22-character password using only lowercase letters could be brute-forced in under four hours on consumer-grade GPU hardware. That wasn't a theoretical exercise — it was a wake-up call. Brute force attack prevention isn&
A Single Password Got Them Into the Colonial Pipeline In May 2021, a single compromised password on an inactive VPN account gave the DarkSide ransomware group access to Colonial Pipeline's network. There was no multi-factor authentication on that account. The attackers didn't need a sophisticated zero-day
