Analogy/Comparison

Imagine a burglar not only breaking into a security guard’s office and stealing their valuables but then using the office’s security cameras and tools to break into other houses the guard was supposed to protect.


Why It Matters

This type of attack is important because it shows how a breach at one company can put many other businesses and their customers at risk. For example, in this case, the NetVampire attack led to the theft of customer data and allowed the attackers to use NetVampire’s infrastructure to conduct new phishing attacks against other victims.

An MSP (Managed Security Service Provider) is a company that manages and protects the computer systems and data of other businesses. A Supply Chain Attack happens when attackers compromise one company, like an MSP, to then gain access to its customers.
