The holy grail of a cyber-attacker is the ability to achieve remote access to a computer on a network. It is even better when the attacker can get administrator privileges. Then they have the ability to do anything they need to do on the compromised computer to cross the network and compromise other computers and servers. Who has this kind of access already? Your IT support provider, that’s who!
So it should be no surprise that cyber-criminals are focusing their attacks on these companies. IT support providers, also known as managed service providers (MSP) often install software agents on the servers and computers they manage for their business clients. The purpose is to monitor all the computers and servers that they manage for emerging issues, while efficiently utilizing computer support personnel. By using remote control sessions, they can service or repair computers in another location without having to physically go on location. In order to do that, they log on remotely as an administrator.
When an MSP is compromised by a cyber-attacker, the bad actors basically have the keys to unlock any computer system that is being managed by the MSP. In my experience, this is often thousands of computer systems, owned by hundreds of businesses. One of those businesses may be yours.
US-CERT and Homeland Security have released warnings about these attacks.
This is a longer article with a lot of technical details that would be important to mitigating this threat on your computer network. If you are an MSP, this is your punch list. If you are a business owner who has contracted with an outside IT Support firm, you will want to get answers to the hard questions posed by this alert. If you are an enterprise class business with your own IT department, and you are using one of these computer and network management system, then you have the same punch list as an MSP.
