File Icons
File Icons
This section displays icon resources found within family samples. Malware often replicates icons commonly associated with legitimate software to mislead users into believing the malware is safe.
Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |
|---|---|---|
| AdTools, Inc. | AdTools, Inc. | Root Not Trusted |
| AdTools, Inc. | AdTools, Inc. | Hash Mismatch |
| AdTools, Inc. | VeriSign Class 3 Code Signing 2001-4 CA | Root Not Trusted |
| ThinkDesktop LLC | VeriSign Class 3 Code Signing 2004 CA | Root Not Trusted |

Registry Modifications
Registry Modifications
This section lists registry keys and values that were created, modified and/or deleted by samples in this family. Windows Registry activity can provide valuable insight into malware functionality. Additionally, malware often creates registry values to allow itself to automatically start and indefinitely persist after an initial infection has compromised the system.| Key::Value | Data | API Name |

Shell Command Execution
Shell Command Execution
This section lists Windows shell commands that are run by the samples in this family. Windows Shell commands are often leveraged by malware for nefarious purposes and can be used to elevate security privileges, download and launch other malware, exploit vulnerabilities, collect and exfiltrate data, and hide malicious activity.
