Mirai Botnet Exploits Ivanti Connect Secure Flaws for Malicious Payload Delivery

Mirai Botnet Exploits Ivanti Connect Secure Flaws for Malicious Payload Delivery

May 09, 2024 Network Security / Botnet
Two recently disclosed security flaws in Ivanti Connect Secure (ICS) devices are being exploited to deploy the infamous  Mirai botnet . That's according to  findings  from Juniper Threat Labs, which said the vulnerabilities  CVE-2023-46805 and CVE-2024-21887  have been leveraged to deliver the botnet payload. While CVE-2023-46805 is an authentication bypass flaw, CVE-2024-21887 is a command injection vulnerability, thereby allowing an attacker to chain the two into an exploit chain to execute arbitrary code and take over susceptible instances. In the attack chain observed by the network security company, CVE-2023-46805 is exploited to gain access to the "/api/v1/license/key-status/;" endpoint, which is vulnerable to command injection, and inject the payload. As  previously outlined  by Assetnote in their technical deep dive of the CVE-2024-21887, the exploit is triggered by means of a request to "/api/v1/totp/user-backup-code/" to deplo...
MITRE Corporation Breached by Nation-State Hackers Exploiting Ivanti Flaws

MITRE Corporation Breached by Nation-State Hackers Exploiting Ivanti Flaws

Apr 22, 2024 Network Security / Cybersecurity
The MITRE Corporation revealed that it was the target of a nation-state cyber attack that exploited two zero-day flaws in Ivanti Connect Secure appliances starting in January 2024. The intrusion led to the compromise of its Networked Experimentation, Research, and Virtualization Environment (NERVE), an unclassified research and prototyping network. The unknown adversary "performed reconnaissance of our networks, exploited one of our Virtual Private Networks (VPNs) through two Ivanti Connect Secure zero-day vulnerabilities, and skirted past our multi-factor authentication using session hijacking," Lex Crumpton, a defensive cyber operations researcher at the non-profit,  said  last week. The attack entailed the  exploitation  of CVE-2023-46805 (CVSS score: 8.2) and CVE-2024-21887 (CVSS score: 9.1), which could be weaponized by threat actors to bypass authentication and run arbitrary commands on the infected system. Upon gaining initial access, the threat actors m...
Protecting Your Software Supply Chain: Assessing the Risks Before Deployment

Protecting Your Software Supply Chain: Assessing the Risks Before Deployment

Feb 11, 2025Software Security / Threat Intelligence
Imagine you're considering a new car for your family. Before making a purchase, you evaluate its safety ratings, fuel efficiency, and reliability. You might even take it for a test drive to ensure it meets your needs. The same approach should be applied to software and hardware products before integrating them into an organization's environment. Just as you wouldn't buy a car without knowing its safety features, you shouldn't deploy software without understanding the risks it introduces. The Rising Threat of Supply Chain Attacks Cybercriminals have recognized that instead of attacking an organization head-on, they can infiltrate through the software supply chain—like slipping counterfeit parts into an assembly line. According to the 2024 Sonatype State of the Software Supply Chain report , attackers are infiltrating open-source ecosystems at an alarming rate, with over 512,847 malicious packages detected last year alone—a 156% increase from the previous year. Traditional sec...
Nation-State Actors Weaponize Ivanti VPN Zero-Days, Deploying 5 Malware Families

Nation-State Actors Weaponize Ivanti VPN Zero-Days, Deploying 5 Malware Families

Jan 12, 2024 Vulnerability / Threat Intelligence
As many as five different malware families were deployed by suspected nation-state actors as part of post-exploitation activities leveraging  two zero-day vulnerabilities  in Ivanti Connect Secure (ICS) VPN appliances since early December 2023. "These families allow the threat actors to circumvent authentication and provide backdoor access to these devices," Mandiant  said  in an analysis published this week. The Google-owned threat intelligence firm is tracking the threat actor under the moniker  UNC5221 .  The attacks leverage an exploit chain comprising an authentication bypass flaw (CVE-2023-46805) and a code injection vulnerability (CVE-2024-21887) to take over susceptible instances. Volexity, which attributed the activity to a suspected Chinese espionage actor named UTA0178, said the twin flaws were used to gain initial access, deploy webshells, backdoor legitimate files, capture credentials and configuration data, and pivot further into the vict...
