To begin with, only a day ago, REvil ransomware gang was revealed to have attacked at least 40 Managed Service Providers (MSPs) through Kaseya – an IT company that is based in Florida and whose VSA software was being used by all the target organizations.

Since these victim MSPs themselves manage data for a number of businesses, the total number of companies estimated to have been impacted are over 1000.

Kaseya helps MSPs to monitor their clients along with automating key processes such as software patches & maintenance. Many believe that the attackers took advantage of the 4th of July holiday weekend in order to benefit from fewer cybersecurity workers in office which can help the ransomware spread faster.

This is why this incident is being termed as a supply chain attack as it targeted a key element in the day-to-day working of all of these victim companies.

In response, Kaseya itself has issued a notice on its website letting users know that all “All on-premise VSA servers should continue to remain down” until they further inform clients on what can be safely done to resume operations. Moreover, they have stated that ultimately a patch will need to be installed.

As a precautionary measure, not only have customers been informed through various channels but the FBI and CISA have also been taken into the loop. Furthermore, the company has also shut down its SaaS servers despite there being no report of their compromise.

Coming to the technicalities, Huntress Labs’, has shared indicators of compromise (IOC) on a reddit thread along with other key information that may help the victims in dealing with the attack:
