What is USB Drop Attack and How to Survive | Rohan Girdhani
Attention USB Drop Attack! Don't Fall into This Trap
You may ask, what is a USB drop attack? and How does it relate to me?
Do note that anyone can be a target of a USB drop attack, and its purpose is to infiltrate your system to access your data using a USB drive to introduce USB drop attack software.
We all know what a USB drive is, we know it's a device we use to transfer and store data. What we may not realize is that it can easily be used to launch data attacks against its unsuspecting user, allowing cybercriminals full access to your system. This is why you do not willy nilly plug just any Flash drive you find into your system.
Introduction About USB Drop Attack
One day the US pentagon/military cannot easily forget is the day they experienced a USB drop attack in November 2008, it was regarded by tabloids as the day “The Worm ate the Pentagon ''. It’s one of the most serious breaches ever discovered on the Pentagon’s classified systems.
This breach was induced via an unsecured USB drive carrying a worm called Agent.biz. This drive was inserted into one of their systems and the warm crawled straight through their DoD's Network protocols, leaving the U.S. government’s top intel agencies compromised.
No one knows till this day who created the bug, who was patient zero, if or when any information was taken and they discovered that all USB drives confiscated from the operative already had the bug, but it took a whole 14 months to completely eradicate the bug.
It took just a flash drive infected with an “agent.btz” virus, inserted into a DoD's computer network to hold the US military ransom. The virus spread quickly throughout their networks, infecting classified and unclassified data alike. This bug opened the door of the US military servers to its creator, so Top secret files and information could be transferred elsewhere. In the end, the US military learned valuable lessons, took steps as well as set up policies to prevent the recurrence of such an attack.
