A remote administration tool (RAT) that bypasses the security features of a program, computer or network to give unauthorized access or control to its user.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
Hupigon variants are backdoor programs, which provide an attacker with access to, and control of, an infected machine. There are a large number of variants in the Hupigon family.
The backdoor's file is a PE executable. The file may be packed with UPX. Unpacked, the code size is 710kB. It is very rare for a Hupigon variant to be smaller than 299kB.
Hupigons are written with Borland Delphi.
The following text strings can typically be found in a Hupigon variant:
When the backdoor's file is started, it copies itself as a file named something similar to "Hacker.com.cn.exe" in the Windows System folder and then uses the following processes to make itself to look like a valid Windows program:
It also makes a number of additions to the registry.
Hupigon variants have several different types of features. The following list is an example of some:
Hupigon doesn't have any automatic mechanisms to spread itself. It must be sent by its author via email, through a website, or even via Instant Messengers (IM) such as Yahoo, MSN, ICQ, and Skype.
Hupigon variants are created using kit software. The kit is maintained in a very professional fashion with a highly developed User Interface (UI).
The main UI of the kit can be seen below:
Many options can be set. The "Fast Configuration" shown below enable the following options:
There is also a "rootkit" option available. Other options including adding a URL to target for a Distributed Denial of Service (DDoS) attack:
The kit as default settings to create mutexes. Many Hupigon variants therefore create mutexes in the following format:
The "xxx" being a variable, for example: Hacker.com.cn_MUTEX
