Cybersecurity in healthcare is a very real threat with the potential to severely disrupt patient care, place extra burden on an already strained system, and result in significant financial losses for a hospital or healthcare network. In October 2020, on the backdrop of the ongoing COVID-19 pandemic, our institution experienced one of the most significant cyberattacks on a healthcare system to date, lasting for nearly 40 days. By sharing our experience in radiology, and specifically in breast imaging, including the downtime procedures we relied upon and the lessons that we learned emerging from this cyberattack, we hope to help future victims of a healthcare cyberattack successfully weather such an experience.
The SMB 1/2/3 protocols allow clients to connect to named
pipes via the IPC$ (Inter-Process Communication) share
for the process of inter-process communication between
SMB clients and servers.
During the month of September, an attacker operating under the pseudonym "kohlersbtuh15", attempted to exploit the open-source community by uploading a series of malicious packages to the PyPi package manager. Based on the names of these packages and the code contained within them, it appears that this attacker targeted developers that use Aliyun services (Alibaba Cloud), telegram, and AWS.
There is no shortage of researchers and industry titans willing to warn us about the potential destructive power of artificial intelligence. Reading the headlines, one would hope that the rapid gains in AI technology have also brought forth a unifying realization of the risks—and the steps we need to take to mitigate them.
A few days ago, ZDI went public with no less than six 0days in the popular mail server Exim. Ranging from ‘potentially world-ending' through to ‘a bit of a damp squib’, these bugs were apparently discovered way back in June 2022 (!) - but naturally got caught up in the void between the ZDI and Exim for quite some time. Mysterious void.
In September of 2023, X-Force uncovered a campaign where attackers were exploiting the vulnerability identified in CVE-2023-3519 to attack unpatched NetScaler Gateways to insert a malicious script into the HTML content of the authentication web page to capture user credentials. The campaign is another example of increased interest from cyber criminals in credentials. The 2023 X-Force cloud threat report found that 67% of cloud-related incident response engagements were associated with the use of stolen credentials.
