The reason for this is the methods used once inside a victim’s systems rarely need to be changed, as they continue to be very effective for the attacker. While the method of gaining a foothold in a victim’s network can vary from these types of attacks on internet-accessible services to spear phishing, the way an attacker moves and acts can remain unchanged for many years. More advanced attackers have taken advantage of recent vulnerabilities in Citrix Netscaler, Progress’ Telerik, and Pulse Secure’s Pulse Connect Secure, to name a few.

The simplest method these attackers use to gain a foothold are simple password spraying attacks against systems that are providing remote access services to the public internet via Remote Desktop Protocol. The attackers will typically target email boxes of specific high-ranking members of organizations or employees researching topics sensitive to their interests. Over the past few years, Rapid7 has observed several different attackers looking to quickly and directly gain access to victim systems in order to collect passwords, perform cryptojacking, distribute ransomware, and/or exfiltrate data. Rapid7 has observed an increased speed between when a vulnerability is disclosed, to the creation and adoption of a working exploit being used en masse, which gives victims little time to test and deploy fixes while adhering to change control process for systems providing mission-critical services.

These devices also commonly fall outside of standard patch management systems. This can lead to challenges, as these devices may be appliances, firewalls, or other devices that do not support running additional security-related software, such as endpoint detection and response. Often, these services are on various edge devices designed specifically to be placed and exposed to the public internet. Attackers of many types are more frequently looking to exploit the network services provided by victims to the public internet. While the reporting on the number of exploited systems has raised alarms for some, events of this scale have been observed by many in the information security industry for many years.
This is one of the most direct routes to what certain attackers are commonly after in a victim’s environment.

In addition to that, these vulnerable servers provide direct access to a great number of user hashes/passwords and email inbox contents of the entire organization. This default configuration does not employ the principle of least privilege and is made even more dangerous as these web applications are created with the intent to be exposed to the public internet and not protected by other basic means like network access control lists.

“Running as a low-privileged account is a good security practice because then a software bug can't be used by a malicious user to take over the whole system.”īecause this service runs with the highest level of permission by default, it should be hardened and receive additional levels of monitoring. One of the major reasons these latest vulnerabilities are so dangerous and appealing to attackers is that they allow them to go directly from the public internet to executing processes as SYSTEM, the most privileged user, on the victim's system. In recent weeks, there has been quite a lot of reporting on the exploitation of the latest disclosed vulnerabilities in Microsoft’s Exchange Server by an attacker referred to as HAFNIUM.
