MSPs have taken a closer look at their cybersecurity in response to a U.S. Secret Service alert of escalating attacks against the providers.

According to the Secret Service alert, a single MSP can service a large number of customers. Therefore cybercriminals are specifically targeting these MSPs to conduct their attacks at scale to infect multiple companies through the same vector, the agency said.

MSPs utilize multiple open source and enterprise software applications to facilitate remote administration, it said. In the event of an MSP compromise, bad actors often use these applications to access their customers’ networks and conduct attacks.

Cybercriminals are leveraging compromised MSPs to conduct a variety of attacks, the agency said. Those include point-of-sale intrusions, business email compromise (BEC) and specifically ransomware attacks.

The agency’s investigations team, the Global Investigations Operations Center, has been seeing an increase in incidents where hackers breach MSP solutions. And they use them as a springboard into the internal networks of the MSP’s customers.

“With our nation’s workforce compelled to work from home and telework for the majority of the time, our enterprises are exposed to an attack surface that we have not seen on a global scale,” he said. “As MSPs, it has become important to make sure that any endpoints connecting to our environments are secure and protected. Our clients have been very receptive to our mutual efforts to ensure we limit the potential attack surface, and we appreciate their willingness to work with us as a provider of their critical services.”
