A similar technique involved the temporary modification of system scheduled tasks by updating a legitimate task to execute a malicious tool and then reverting the task back to its original configuration. [43], Hackers have exploited the vulnerabilities to spy on a wide range of targets, affecting an estimated 250,000 servers. [4] Wired reported on 10 March that now that the vulnerability had been patched, many more attackers were going to reverse engineer the fix to exploit still-vulnerable servers. The Kaseya ransomware attack was reminiscent of the notorious 2020 Solarwinds attack, which. SolarWinds, based in Texas, United States of America, provides a platform called Onion which helps numerous companies, many of which are Fortune 500 companies and include government agencies such as the Pentagon, to manage their IT resources. Attackers then typically use this to install a web shell, providing a backdoor to the compromised server,[37] which gives hackers continued access to the server as long as both the web shell remains active and the Exchange server remains on.

On 8 March, CISA tweeted what NBC News described as an "unusually candid message" urging "ALL organizations across ALL sectors" to address the vulnerabilities. Attackers typically install a backdoor that allows the attacker full access to impacted servers even if the server is later updated to no longer be vulnerable to the original exploits. The company also plans to release a new hotfix 2020.2.1 HF 2 on Tuesday that will replace the compromised component and make additional security enhancements. That, however, was just the tip of the Hackers had initially pursued specific targets, but in February they started going after more servers with the vulnerable software that they could spot, Krebs wrote.
