The Hacker News reported on the latest developments in deception technology which made it more affordable.
A cyber-attacker successfully breaks into your environment and begins sneaking around to find something valuable – intellectual property, bank account credentials, company plans, whatever. The attacker makes his way to a certain host on a network node to browse the directories, and suddenly, his connection is cut off. The stolen username and password he acquired no longer works.
Unknowingly, the attacker triggered a well-concealed trap that detected his presence, took immediate action to sever his connection, and then blocked his reconnect ability. Very cool.
