Microsoft has been investigating recent attacks by malicious actors using the Dopplepaymerransomware. There is misleading information circulating about Microsoft Teams, along with references to RDP (BlueKeep), as ways in which this malware spreads. Our security research teams have investigated and found no evidence to support these claims. In our investigations we found that the malware relies on remote human operators using existing Domain Admin credentials to spread across an enterprise network.
Unbound 1.6.4 through 1.9.4 contain a vulnerability in the ipsec module that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with `--enable-ipsecmod` support, and ipsecmod is enabled and used in the configuration.
Were you unable to attend BlueHat Seattle, or wanted to see a session again? We have good news. If you have been waiting for the videos from BlueHat Seattle last month, the wait is over. All videos which the presenter authorized to be recorded are now online and available to anyone.
This Saturday 9th of November, there will be a keynote from Microsoft engineers Ryan Levick and Sebastian Fernandez at RustFest Barcelona. They will be talking about why Microsoft is exploring Rust adoption, some of the challenges we’ve faced in this process, and the future of Rust adoption in Microsoft. If you want to talk with some of the people working on how Microsoft is evolving its code practices for better security, be sure to attend the keynote and talk to Ryan and Sebastian afterwards!

In two previous blog posts ( part 1 and part 2), we talked about using Semmle QL in C and C++ codebases to find vulnerabilities such as integer overflow, path traversal, and those leading to memory corruption. In this post, we will explore applying Semmle QL to web security by hunting for one of the most common type of client-side vulnerabilities: DOM-based cross-site scripting (XSS).
A buffer overflow vulnerability exists in the PowerPoint document conversion function of Rainbow PDF Office Server Document Converter V7.0 Pro MR1 (7,0,2019,0220). While parsing a document text info container, the TxMasterStyleAtom::parse function is incorrectly checking the bounds corresponding to the number of style levels, causing a vtable pointer to be overwritten, which leads to code execution.
In axohelp.c before 1.3 in axohelp in axodraw2 before 2.1.1b, as distributed in TeXLive and other collections, sprintf is mishandled.
We hope you enjoyed the first day of our BlueHat briefings and the Bytes of BlueHat reception in our glamping tent (complete with toasted marshmallows). Yesterday, we learned a lot about how XboxOne hardware security has advanced the state of hardware security elsewhere, we heard some surprising correlations between vuln severity, age, and time to fix, and we saw applications for machine learning for malware detection—as well as some of the attack surface for machine learning and how to protect it.
We’ve finished two incredible days of security trainings at the Living Computer Museum in Seattle. Now it’s time for the second part of BlueHat: the briefings at ShowBox SoDo. We’ve got a big day planned, so head on down. Please join us for breakfast (we have doughnuts! and bacon! and cereal!
