{Updated on November 12}:<\/strong> Palo Alto Networks’ cybersecurity researchers warn of a continuing cyberespionage campaign that has already infiltrated at least nine enterprises, including those in the defence, healthcare, and energy sectors. Following the initial intrusion, the threat actors allegedly installed either a Godzilla webshell or a new backdoor known as NGLite, which allowed them to perform commands and move around while exfiltrating files of interest.<\/p>\n

 <\/p>\n

On November 8, 2021, Microsoft found DEV-0322, a chinese based threat group, exploiting the ZOHO ManageEngine ADSelfService Plus software versions vulnerable to CVE-2021-40539. This threat group had previously been observed in attacks targeting the SolarWinds Serv-U software with 0-day exploit<\/a>.<\/p>\n

 <\/p>\n

The FBI<\/a>, CISA<\/a>, and the Cyber Guard (CGCYBERs)<\/a> warned of a serious vulnerability (CVE-2021-40539) in a single Zoho Signup and Password Management Solution that State Advanced Persistent Threat (APT) actors are actively scanning the internet for vulnerable servers.<\/p>\n<\/blockquote>\n

Zoho discovered a zero day vulnerability existing in the Zoho ManageEngine ADSelfService Plus software – a password management solution that might allow threat actors to take control of the system. Handed the label CVE-2021-40539<\/a>, the bug has a severity rating of 9.8 out of 10, and is a remote code execution flaw.<\/p>\n

 <\/p>\n

On September 06, 2021, a patch<\/a> was released for this critical remote code execution flaw. More specifically, this vulnerability is an authentication bypass issue that can affect the REST API URLs in ADSelfService Plus. Organizations using Zoho ManageEngine ADSelfService that haven’t yet applied a patch are at heightened risk of compromise.<\/p>\n

Attackers Aiming for Unpatched Servers<\/h2>\n

 <\/p>\n

CISA\u2019s advisory notice<\/a> makes it explicit, stating that CVE-2021-40539 has been identified as being exploited in the wild. Proper exploitation of this issue might lead to a serious threat to critical infrastructure in organizations that use the servers.<\/p>\n

 <\/p>\n

According to researchers at security firm Crowdstrike, CVE-2021-40539 has been under attack for more than a week even before the attacks against Confluence Servers<\/a> began.<\/p>\n

<\/a><\/p>\n

The Port of Houston<\/a>, a vital piece of Gulf Coast infrastructure, recently disclosed that it had successfully fought against an attempted breach in August and no functional data or systems were affected. Officials suspect that nation-state actors are behind the hack that involves ManageEngine ADSelfService Plus. Therefore, patching the Zoho Servers are crucial at the moment.<\/p>\n
