Threat Actors Actively Exploiting Critical Fortinet; Veeam Backup & Replication Vulnerabilities
Ransomware actors have been observed exploiting a critical vulnerability in Veeam Backup & Replication, a data protection and recovery solution for virtual, physical, network-attached storage, and cloud-native environments. The deserialization of untrusted data vulnerability – CVE-2024-40711 – can lead to remote code execution and has a CVSS severity score of 9.8. According to Sophos, ransomware groups have been observed using compromised VPN credentials to access VPN gateways without multifactor authentication enabled, and then exploiting CVE-2024-40711 to create new local administrator accounts to deploy Akira and Fog ransomware. Sophos has tracked several attacks in the past month that exploited the vulnerability. While ransomware deployment was not always successful, in one of the attacks the threat actor successfully dropped Frog ransomware on an unprotected Hyper-V server and used rclone to exfiltrate data. The vulnerability affects Veeam Backup & Replication version 12.1.2.172, and potentially also unsupported versions. Veeam released a patch to fix the...
CISA Warns F5 BIG-IP Users About Abuse of Unencrypted Cookies
The US Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning to F5 BIG-IP users that threat actors are abusing unencrypted persistence F5 BIG-IP cookies to map internal servers and identify potentially vulnerable devices on the network that can be attacked. F5 BIG-IP is a widely used suite of hardware and software solutions for managing and securing network traffic. One of the core modules is the Local Traffic Manager (LTM), which is used to manage traffic and spread it across different servers to optimize load-balanced server resources and ensure high availability. To maintain session consistency, the LTM module uses persistence cookies to ensure traffic from specific clients is delivered to the same server each time. According to CISA, threat actors have been observed leveraging the unencrypted persistence cookies that are managed by the LTM module during the planning stage of a cyberattack to enumerate other non-internet-facing devices on the network. The information gathered from the cookies, which can include IP addresses, port numbers, and load...
