What is computer worm?
A computer worm is a type of malware that spreads automatically from one device to another—without any user interaction. Unlike a virus, which requires someone to open or install something, a worm can replicate and travel on its own via networks, email, or shared systems.
Think of a computer worm as a digital stowaway that moves freely between systems, leaving damage behind at each stop.
Example
One of the most well-known worms, WannaCry, spread globally in 2017 by exploiting a Windows vulnerability. It required no user action and disrupted operations across sectors.
Sicra and computer worm
Sicra helps organizations defend against worms through continuous monitoring, vulnerability management, and proactive security testing. This includes identifying weak points, isolating infected systems, and closing attack paths before they spread.
Worms are especially dangerous in environments with poor segmentation or extensive connectivity—areas where Sicra provides critical security expertise.
