Underscores and DNS: The Privacy Story, (Wed, Aug 31st)

The use of underscores in DNS records can easily trigger DNS purists into a rage. Since the beginning of (DNS) time, only the letters a-z, numbers, and dashes are allowed in DNS labels (RFC 1035 section 2.3.1). After all, we want to remain compatible with ARPANET.


Jolokia Scans: Possible Hunt for Vulnerable Apache Geode Servers (CVE-2022-37021), (Thu, Sep 1st)

On Tuesday, the Apache project released an update for Geode. The update patches a typical deserialization issue we often see in Java software like Geode (CVE-2022-37021). [...] But the vulnerability has a few dependencies: [...] JMX and RMI are used for the attack. [...] And here comes Jolokia. "JMX on Capsaicin," as it calls itself. It provides a simple HTTP to JMX gateway. So it is somewhat interesting that I also saw some scans for Jol[o]kia starting yesterday.

RAT Tool Disguised as Solution File (*.sln) Being Distributed on Github

The ASEC analysis team has recently discovered the distribution of a RAT Tool disguised as a solution file (*.sln) on GitHub. As shown in Figure 1, the malware distributor is sharing a source code on GitHub titled -Jpg Png Exploit Downloader Fud Cryter Malware Builder Cve 2022-. The file composition looks normal, but the solution file (*.sln) is actually a RAT tool. It is through methods like this that the malware distributor lures users to run the RAT tool by disguising it as a solution file (*.sln). Generally, programmers who receive the code that includes the solution file run the file in order to open the project. Users should take caution against social engineering techniques that take advantage of such a thought process.
