Key details of these vulnerabilities are summarized in the table below: CVE / CVSSĪPT Actors, BlackKingdom Ransomware, Groove Ransomware, Ma ze Ransomware, Netwal ker Ransomware, REv il Ransomware Unfortunately, attackers were not done with Pulse Secure, and in April of 2021, reports surfaced that APT actors were targeting defense, government, and financial organizations via a new zero-day Pulse Secure vulnerability CVE-2021-22893. REvil in particular is well-known for extorting vast amounts of money from victims, including an $11 Million ransomware extorted from meat processor, JBS. These same techniques were quickly adopted by some of the most destructive ransomware groups in the wild including Maze, Netwalker, and REvil. These vulnerabilities became very popular with a variety of APT actors, and CISA has subsequently published multiple alerts highlighting the ongoing exploitation of these vulnerabilities by threat actors from Iran, Russia, and China. These vulnerabilities enable unauthenticated attackers to capture keys and inject commands, ultimately enabling the actors to gain initial access to networks, spread laterally, and deliver additional malware payloads. On October 7th, 2019, the NSA Issued a Cybersecurity Advisory (PDF) detailing the use of CVE-2019-11510 and CVE-2019-11539 by multiple nation-state APT.

To date, attackers have primarily focused on five vulnerabilities related to critical Pulse Secure devices that span arbitrary file reads, remote code execution, authentication bypass and other high-severity issues. Pulse Secure Vulnerabilities Attacked in the Wild Security teams need to understand what makes these vulnerabilities unique, how they are being attacked in the wild, and the key steps to mitigate their risk. Pulse Secure also highlights the critical role that firmware plays in today’s enterprise attack surface. Pulse Secure VPN devices have proven to be the most popular targets, and their ongoing exploitation highlights how devices that were intended to defend the network are increasingly being exploited to cause damage. Vulnerabilities in enterprise network and security devices are being aggressively targeted by APT and ransomware threat actors as initial access vectors into enterprises.
