Zero-day vulnerabilities enable threat actors to take advantage of security blindspots. Typically, a zero-day attack involves the identification of zero-day vulnerabilities, creating relevant exploits, identifying vulnerable systems, and planning the attack. The next steps are infiltration and launch.  This article examines three recent zero-day atta

While exploit kit activity has been fairly quiet for some time now, we recently discovered a threat actor creating a copycat—fake—Malwarebytes website that was used as a gate to the Fallout EK, which distributes the Raccoon stealer. The few malvertising campaigns that remain are often found on second- and third-tier adult sites, leading to the Fallout or

It was discovered and fixed in 2014, yet today—five years later—there are still unpatched systems.  This article will provide IT teams with the necessary information to decide whether or not to apply the Heartbleed vulnerability fix. However, we caution: The latter c
