Timeline of the MOVEit mass exploit: Unraveling how the file-transfer service ensnared its victims, attacking them en masse
In the realm of cybersecurity, the past few years have seen a series of significant data breaches, with one of the most notable being the MOVEit file-transfer vulnerabilities. These vulnerabilities, discovered and documented since 2023, have been a source of concern for organizations worldwide, particularly due to their active exploitation.
One of the most critical SQL injection vulnerabilities, CVE-2023-34362, has affected Progress MOVEit Transfer software versions before certain patched updates. This vulnerability was exploited as early as May 2023, causing major breaches, including the Colorado Department of Health Care Policy & Financing (HCPF), affecting millions of individuals. The consequences of this breach have been far-reaching, leading to ongoing legal and regulatory issues.
CVE-2023-34362 has been widely exploited to install webshells and extract data, as confirmed by security advisory and monitoring organizations. On the other hand, CVE-2023-35708, an improper authorization vulnerability in MOVEit Transfer versions up to 15.0.2, is classified as critical but has a lower exploitability. As of the latest reports, there is no known exploit publicly available for this vulnerability.
Organizations across various sectors, including healthcare entities and government agencies, have suffered from these breaches. Notable victims include the National Student Clearinghouse, PBI Research Services, TIAA, Zellis, and many others. The attack campaign has affected over 100 organizations, with at least 314 victim organizations identified to date.
To mitigate these vulnerabilities, security advisories recommend upgrading to fixed versions released through 2023 and later. Patching and isolating compromised systems are crucial steps to limit further exploitation. The Cybersecurity and Infrastructure Security Agency and the FBI have also released a joint advisory to share recommendations for organizations at risk of compromise.
It's important to note that these are not the only file-transfer service vulnerabilities to be exploited this year. The Clop ransomware group, responsible for two of these supply-chain attacks, has also exploited a zero-day vulnerability in Fortra's GoAnywhere file-transfer service in March and a vulnerability in IBM Aspera Faspex.
The attacks on MOVEit mark the third actively exploited zero-day vulnerability in a file-transfer service this year. With more than 2,650 organizations impacted by Clop's mass exploitation of a zero-day vulnerability in MOVEit, it's clear that these vulnerabilities pose a significant threat to data security.
As the landscape of cyber threats continues to evolve, it's essential for organizations to stay vigilant and proactive in their security measures. Regular updates, patching, and system hardening are crucial steps to prevent further attacks. By doing so, we can work towards a safer digital future.
