Re: "Transparent"
It's because of how the exploit drops directly into RAM bypassing any security software. This teqnique is nothing new. The dropper can be encoded dozens of times to such a point that even using the most advanced file heuristic analysis it goes undetected.  It also has polymorphic properties so it is capable of self modifying it's own code to further evade detection. This makes signature based detection also useless. Another method used is covert application channels where shell code is injected into a file such as calc.exe or system file and the digital file signature is also forged. All connections established by the RAT are fully encrypted utilizing Reverse_TCP connection method. Because the infected system is 'phoning home' it in most cases is allowed through the firewall. One way to prevent this connection attempt is to have proper implicit deny ACLs in place. However, one would have to be able to monitor and identify the outgoing encrypted traffic or any network traffic for that matter and verifiy it is in fact legitimate. Constant whitelisting would need to be properly applied without the distruption of 'Normal' traffic. I do not see any practical solution to this in the near future.

Re: "Transparent"
The transparency or "invisibility" comes through the faulty certificate and, possibly, from other characteristics that make it behave like an innocent file.

Security Measures
What security measures and best practices should be used for a trojan that is detectable only via network forensics and specialized tools that are capable of detecting suspicious activity on endpoint systems? Also, what are these "specialized tools"?

Incorporating a Prevention Mindset into Threat Detection and Response
Threat detection and response systems, by definition, are reactive because they have to wait for damage to be done before finding the attack. With a prevention-mindset, security teams can proactively anticipate the attacker's next move, rather than reacting to specific threats or trying to detect the latest techniques in real-time. The report covers areas enterprises should focus on: What positive response looks like. Improving security hygiene. Combining preventive actions with red team efforts.

PUBLISHED: 2022-05-21
Gitblit 1.9.2 allows privilege escalation via the Config User Service: a control character can be placed in a profile data field, such as an emailAddress%3Atext '[email protected]\n\trole = "#admin"' value.
CVE-2022-31268
PUBLISHED: 2022-05-21
A Path Traversal vulnerability in Gitblit 1.9.3 can lead to reading website files via /resources//../ (e.g., followed by a WEB-INF or META-INF pathname).
CVE-2022-31264
PUBLISHED: 2022-05-21
Solana solana_rbpf before 0.2.29 has an addition integer overflow via invalid ELF program headers. elf.rs has a panic via a malformed eBPF program.
CVE-2022-31259
PUBLISHED: 2022-05-21
The route lookup process in beego through 1.12.4 and 2.x through 2.0.2 allows attackers to bypass access control. When a /p1/p2/:name route is configured, attackers can access it by appending .xml in various places (e.g., p1.xml instead of p1).
