Ransomware assaults focusing on the availability chain are rising in frequency, together with the price of ransom funds. Within the first half of 2021, the common ransomware cost totaled $512,000, a 171% improve from $312,000 in 2020. Extra so, the quantity these attackers request has additionally elevated, with the common ransomware demand in 2021 being $5.3 million, up 518% from the 2020 common of $847,000.
One safety incident specifically, the Kaseya ransomware assault, introduced consideration to a brand new wave of ransomware assaults particularly focusing on managed service suppliers (MSPs), which regularly function the safety lifeline for small to medium-sized companies. These assaults give cybercriminals entry to the MSP supplier, the organizations it serves, and lots of the organizations’ buyer networks as properly — making a ripple impact of digital havoc. These assaults are additionally a lot tougher to stop, since they typically exploit staff on the firm who suppose they’re performing on a regular basis duties like logging in to electronic mail. This challenge has change into extra prevalent, particularly with the shift to hybrid work. As increasingly gadgets are linked to the cloud, the tougher it’s to safeguard these endpoints from attackers.
Let’s discover how organizations can higher put together themselves and their prospects for these assaults sooner or later, and among the methods to establish the threats earlier than they change into a widespread challenge.
Belief No One: Zero Belief as a Prevention MechanismWith the Kaseya assault, the REvil ransomware group was capable of bypass authentication by merely sending a word password, granting them a session cookie that allowed them to have a low key the place they might add recordsdata onto the Kaseya VSA server. This was a reasonably easy exploit that would have been prevented if there had been extra stringent habits detection practices in place, which will be achieved by zero belief.
The elemental precept behind zero belief is that any entity attempting to hook up with an enterprise useful resource needs to be validated for compliance in opposition to a set of predetermined attributes earlier than it might probably join and keep linked to that useful resource. In impact, its premise is to think about anyone and something working inside or outdoors the enterprise community as hostile.
Not solely ought to the MSP undertake zero belief, however organizations working with such suppliers also needs to contemplate implementing such a framework, particularly to raised safe a really weak third-party provide chain.
Efficient Incident Response With Clearly Outlined PoliciesMSPs and their prospects’ safety groups all know the everyday workflow in terms of responding to threats. One thing will probably be flagged as irregular, a ticket will probably be created, and any crucial knowledge is aggregated into the safety platform of alternative. Then evaluation is carried out with actionable steps on tips on how to reply. Nevertheless, guaranteeing these processes have clear, outlined roles the place each particular person engaged on the workforce is aware of precisely tips on how to reply is essential in a lot of these conditions.
Among the best methods to guarantee all events concerned within the provide chain perceive their duties is to carry out common tabletop workout routines, which simulate varied sorts of incident response eventualities. Did the attackers breach the community utilizing phishing methods? Was the risk vector a JPEG file with malicious code? At the moment’s attackers are at all times discovering new methods to infiltrate a community, together with focusing on MSPs to then get to bigger-ticket alternatives, so it is vital to be ready.
Data Sharing for a Proactive Safety PostureIt’s necessary to be repeatedly evolving and studying from previous safety occasions, particularly these just like the Kaseya incident that characteristic much less widespread entry mechanisms focusing on an MSP. A main means to assist stop such assaults is by proactively sharing data, risk analysis, knowledge, or options with different prospects — creating an information-sharing alliance.
As a safety group, defending your prospects is your No. 1 precedence, and most of the time, your prospects will share related points in terms of stopping breaches. If a buyer has a safety framework much like one which was simply breached, there’s doubtless data discovered out of your groups that can be utilized to conduct proactive risk attempting to find others.
For instance, with the Kaseya assault, we analyzed our prospects’ networks and located a number of of them had misconfigured firewalls, permitting all their providers to be seen. We had been capable of establish these missteps and remediate them, whereas additionally sharing data with others who could have discovered this useful.
With the return on funding throughout an MSP cyberattack being a lot larger than ordinary for cybercriminals, we are able to anticipate a lot of these distributors to change into a extra well-liked goal for risk actors. With efficient safety insurance policies in place throughout an MSP and its buyer networks, paired with a zero-trust framework, MSPs and their whole ecosystem will probably be higher ready for the subsequent inevitable risk.
