WiseVector StopX V2.65

June 7, 2020

1. Improved Memory Protection to detect malware by abusing whitelist applications, such as Powershell, msbuild.exe, installutil.exe, regasm.exe, etc. It can effectively detect advanced threats based on tools such as PowerShell Empire, GreateSCT, nps_payload, ObfuscatedEmpire, unicorn, etc. Since it detects malicious payload in memory, it can effectively detect obfuscated malicious scripts.
2. Instruction Tracer improved. Recently, we have observed lots of RAT Trojans utilizing DLL hijacking to avoid detection by AV. These Trojans abuse whitelist APPs like Avast & ESET as well as APPs which are released by Samsung, TeamViewer, Citrix to perform DLL Side-Loading. We updated Instruction Tracer to make sure they can be detected without needing signature updates.

3. Fixed other bugs.

WiseVector StopX V2.60 Beta

April 30, 2020

1. Upgraded the AI engine to improve detection rate and reduce false positives. Users can adjust the protection level according to their needs. It should be noted that the protection level only affects static scanning and basic real-time monitoring, and does not affect behavior analysis and memory protection.

2. Added the instruction tracer module.This technique makes identifying the original source of the malicious behavior in applications. It can effectively detect hidden threats such as DLL Side-Loading, thread hijacking and so on. At the same time, it can also detect stealth attacks in post-injection phase.

3. Improved the detection of Info stealer malware. Info stealer malware is designed to harvest a variety of data (Browser Passwords, Cookies, FTP credentials, etc.,) on the computers. They usually minimize their behavior to decrease the chance of detection by AV. Most of them hide their presence on the system by using advanced malware stealth techniques such as injection, hollowing, etc.. Based on their characteristics, we have added multiple modules to memory protection and behavioral analysis to detect them.

4. Improved the memory protection. Besides the Info stealer detection module we mentioned above. We also added multiple RAT detection modules, which can detect RAT uses DLL hijacking to evade the behavior monitoring (Gh0st, Parallax, etc.,). At the same time, the conflicts between memory protection with other security software is resolved. and also reduces the CPU consumption.

5. Improved Ransomware detection. We added several ransomware detection modules which can terminate the behavior of ransomware at an earlier stage.

6. Privacy protection got improved which can protect users from webcam and microphone spying.

7. Improved MBR and partition table protection.

8. Fixed the issue that may cause BSOD under certain conditions.

9. The user can set whether to turn on a specific component of the basic real-time monitoring.

10. We optimized code to reduce CPU consumption and disk I/O. 2.6 is even lighter than the previous versions.

11. Fixed other bugs.

WiseVector StopX V2.50 Beta

January 17, 2020

1. Engine improved: We brought deep reinforcement learning to the training process. This method makes the classifier to be trained continuously on samples that are easy to misclassify to get better detection results. We also performed feature engineering again. After the above efforts, the accuracy of the engine has been improved.
2. We added a module to detect a class of banking Trojans. Such Trojans often use MSI installation packages to release DLL Side-Loading. The size of the DLLs is generally large, so AV based on Cloud usually cannot detect them, but our new module has a detection rate of more than 98% for such DLLs.
3. Faster scanning speed.
4. We used a graph-based algorithm internally to save the running logs of the program. In the new version we have optimized the algorithm to make the speed of the Behavior Detection several times faster in some specific cases, including the process launching multiple child processes, or the program itself is larger, etc. Users will experience a speed increase when compiling programs or editing files with some specific large software.
5. Added Memory Detection. It detects malware that uses the following technologies:

Reflective Dll Injection,
Process Hollowing,
Manually PE loading (Exe and Dll),
DotnetToJS, Sharpshooter, Net code in PowerShell.
Process Doppelgänging
Process Reimaging
As well as remote threads in system processes.
Since many advanced attacks currently use the above method, it is foreseeable that our Memory Detection will greatly help users to keep from advanced threats.
6. Added protection against ransomware using RIPlace technique, while Document Protection also protects against ransomware using this technique.
7. The Behavior Detecion has been improved in multiple detection links, such as injecting other programs, stealing system credentials, loading hidden locations, using WMI, etc.
8. The Behavior Detection added a program protection feature to protect system programs that are easily used by some advanced attack techniques, for example, RegAsm.exe, msbuild.exe, rundll32.exe, powershell, etc.. Our Behavior Detection will protect the PowerShell process from being injected by other programs, and other programs cannot be injected into PowerShell.
9. Improved usability: The tray right-click menu is easier to use. Meanwhile, we have redesigned the main malware report name to make it more friendly to users skilled in PC. They can learn the behavior of malicious programs from the main malware name.
10. Fixed multiple bugs.
