Ransomware is insidious. It is constantly evolving with new variants appearing literally every 18 seconds. That’s 4800 new ransomware code every single day or more than 1.75 million per year. This is a multi-billion USD business. It’s organized criminality and frequently state sponsored. The profits to cybercriminals are compelling.
Authorities continue to advise the best response to a ransomware attack is a good backup and NOT to pay the ransom. It’s good advice that is frequently ignored. The cybercriminals’ price their ransom to make it attractive to pay the nuisance cost versus the time and cost required to recover. Unfortunately, there are consequences for paying the ransom.
The cybercriminals also know the best way to force a ransom and ensure their revenue stream, is to make the backups disappear or become ineffective. The best way to make them disappear is by deleting the backups via stolen credentials or via the data protection software published API. Should that fail they will use a Trojan Horse strategy of infect and wait to detonate. This enables the data protection software to back up the infections. When the ransomware finally detonates, recovering from the backups re-infects and re-encrypts the primary data. This is known as an “Attack-Loop”.
What does this have to do with Remote monitoring and management (RMM)? That requires a brief explanation of what RMM is, what it does, and how ransomware is exploiting it.
RMM software helps managed IT service providers (MSPs) remotely and proactively monitor client endpoints, networks and computers. It was historically called remote IT management. Deploying RMM requires an agent installed on client servers, hypervisors, workstations, networking devices, laptops, and other mobile endpoints. The agents continuously report device health information and status back to the MSP providing client insights. For the MSP, it keeps client on-prem machines up-to-date while proactively dealing with problems and issues, often before the client is aware there is one. The RMM issues tickets or alerts to the MSP when it detects a problem classifying them based on severity, problem type, criticality, etc. This is why RMM has become so popular among MSPs.
The main purpose and tasks of RMM have been in summary:
RMMs appear to be extremely helpful (and profitable) tool for MSPs. And RMMs have not stopped evolving. Many have tightly integrated backup software today so the MSP can provide backup as a service (BaaS) and DR as a service (DRaaS) as part of their software platform. Several RMM vendors purchased backup software to specifically integrate with their RMMs. Single sign-in and more services in a single UI. All good for the MSP? Maybe not. This is where ransomware has come into the picture. Remember, the cybercriminals want to eliminate or at least mitigate the ability of the backups to stop their attack. This has made RMMs with integrated backups incredibly attractive to their potential revenues.
The next blog will cover the RMM ransomware attack vector; how their frequency is increasing; and what MSPs can do to dramatically reduce their exposure.
