Choosing your MSP: What the Kaseya incident tells us about third‑party cyber‑risk

July 23, 2021

Classes to study from the Kaseya cyberincident to guard your online business’ knowledge when doing enterprise with a MSP.

Managed service suppliers (MSPs) play a crucial function within the IT ecosystem. By outsourcing a lot of their day-to-day IT necessities to those firms, smaller organizations specifically can save prices, enhance service ranges and focus extra sources on rising the enterprise. In concept, they will additionally cut back safety threat by handing over to a extra succesful and well-resourced supplier. Nonetheless, because the ransomware marketing campaign impacting Kaseya clients has illustrated, MSPs will also be a supply of cyber-risk.

Amidst immediately’s unstable risk panorama, these dangers are always evolving. That places extra strain on organizations to make sure they’re asking the correct due diligence questions of potential suppliers earlier than signing contracts.

What occurred at Kaseya?

Kaseya is an IT administration software program supplier whose principal purchasers are MSPs. Its VSA product delivers automated software program patching, distant monitoring and different capabilities in order that these firms can seamlessly handle their clients’ IT infrastructure. In the same solution to SolarWinds Orion, the product requires extremely privileged entry to buyer environments to function. This makes it an ideal selection for attackers in search of an efficient, excessive ROI risk vector.

That’s precisely what occurred on July 2. As outlined on the vendor’s service update page, risk actors used the platform to compromise scores of MSPs and hearth a pretend replace to their clients, containing REvil/Sodinokibi ransomware. Round 50-60 MSPs had been affected, and within the area of 1,500 downstream clients. How did they do that? It’s now been reported that the risk actors exploited between one and three zero-day vulnerabilities within the on-premises Kaseya VSA product, beating the seller’s personal safety workforce, who was engaged on patches for the bugs on the similar time. These are:

This enabled them bypass authentication within the internet interface of MSPs’ on-premises Kaseya VSA. They then used the session to add their payload and execute instructions through SQL injection. On the time of writing, a patch was lastly being rolled out to on-premises clients, whereas most SaaS MSPs are already again on-line.

Why are MSPs dangerous?

This isn’t the primary time Kaseya has been focused by ransomware teams. In 2019, threat actors exploited a vulnerable plugin for Kaseya VSA which enabled them to compromise a single MSP buyer. With administrator-level entry to the software program, they had been capable of execute ransomware on each buyer system it was managing—resulting in between 1,500 and a couple of,000 clients turning into infested with the GandCrab ransomware variant.

Though GandCrab has been linked to REvil, there’s no suggestion that these assaults had been perpetrated by the identical group. However in any case, the cybercrime underground does a much better job of sharing intelligence and tooling than the infosec neighborhood. Which means if assaults have been confirmed to work prior to now, they’ll normally be repeated sooner or later. That is dangerous information for MSPs and their clients, as there’s a mounting physique of historic proof that exhibits campaigns in opposition to MSPs will be extremely profitable.

A number of the highest profile assaults prior to now have been the work state-backed operatives. These include Operation Cloud Hopper, an audacious multi-year scheme attributed to APT10 that impacted “an unprecedented internet of world victims.” The distinction immediately is that it’s now financially motivated cyber-criminals who’re concentrating on MSPs. In keeping with one recent report, 73 % of MSPs reported no less than one safety incident over the previous yr and 60 % of those had been ransomware-related.

Cybercrime is huge enterprise immediately. And it makes whole enterprise sense to spend time researching and concentrating on a single group that may present entry to doubtlessly 1000’s extra, than to focus on these downstream clients individually. In spite of everything, MSPs have consumer knowledge and privileged entry to those organizations. In keeping with some estimates there might be as many as 20,000 such MSPs serving a number of clients in North America alone immediately. And never all of them are as secure as they should be. That’s a major goal for risk actors to intention at.

The way to handle MSP threat

Market dynamics ought to imply that MSPs that persistently fail their clients on safety ultimately give solution to these with a stronger cyber-risk administration posture. There’s no scarcity of instruments available on the market to help these providers differentiate on safety. Nonetheless, this solely works if clients are well-informed sufficient to vote with their ft.

To that finish, listed below are some fundamental due diligence checks and questions to think about earlier than selecting your subsequent MSP:

  • What’s their patch/vulnerability administration program like?
  • Which software program companions do they work with and what’s their fame like for safety/high quality assurance?
  • Do additional checks on any MSP software program working with excessive privileges
  • Do they run the eight essential controls for MSPs? (These are: app whitelisting, patching and hardening, proscribing administrative privileges, multi-factor authentication, OS patching, every day backups, and adjusting Workplace macro settings)
  • Have they got strong anti-malware safety throughout servers, endpoints, networks, e-mail, cloud methods and many others.?
  • Do they function a least privilege entry coverage and community segmentation to attenuate the assault floor?
  • Do they commonly practice and replace employees in phishing consciousness?
  • Do they undertake common and complete safety audits/critiques?
  • Do they run prolonged risk detection and response (XDR) for proactive safety?
  • Have they got a well-rehearsed incident response plan within the occasion of a worst-case situation?
  • What trade requirements, certifications and frameworks do they observe?

Due diligence checks like this gained’t insulate your group 100% from a safety incident involving an MSP. However they’ll assist to cut back the chance of 1. And immediately, that’s about pretty much as good as you are able to do.
