Banprox Trojan – How Is It Spread
Similar to Banload Infostealer, this Trojan is mostly distributed via malicious macros in e-mail attachments and what is worse is that most users get caught while opening them. Since a user tends to trust documents with .docx, .doc, .pdf, .ppt and other Microsoft Office documents, they often lack the knowledge that such documents may have malicious macros. And often the emails may resemble an important subjects such as:
- Your PayPal receipt.
- Your Amazon gift card has arrived.
- The funds have been transferred to your eBay account.
After the document is opened and the user chooses the “Enable” editing option, the malicious macro may execute a script that may either directly deploy the payload of the Trojan or connect to a remote host and download the obfuscated payload.
Banprox Trojan – How Does It Work
The concept of banking Trojans is not a new thing when we are talking about cyber-security. Symantec researchers have reported that after it has been started, the Trojan immediately attacks the registry entries, creating several new ones in these locations:
→ `HKEY_ALL_USERS\S-1-5-21-3889344330-28187927-3519877804-1000\Software\Microsoft\Internet Explorer\Privacy\”CleanTIF” = “1”
HKEY_ALL_USERS\S-1-5-21-3889344330-28187927-3519877804-1000\Software\Microsoft\Internet Explorer\Privacy\”ClearBrowsingHistoryOnExit” = “1”
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\”AutoConfigUrl” = “[LOCATION OF CONFIGURATION SCRIPT]”
HKEY_ALL_USERS\S-1-5-21-3889344330-28187927-3519877804-1000\Software\Microsoft\Windows\CurrentVersion\Internet Settings\”AutoConfigURL” = “[LOCATION OF CONFIGURATION SCRIPT]”
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\”AutoConfigURL” = “[LOCATION OF CONFIGURATION SCRIPT]”`
The registry values that have the location of configuration scrips directly point out to keys configured to connect and transfer web traffic via custom created web links from two main hosts:
An example of a custom host may be the following:
These scripts of the hosts contain a list of websites that are set as parameters to collect data from and it is activated every time the user visits the website from that list. Here are several examples of websites the traffic to which may be redirected to another server and hence the user-entered information may be stolen:
Furthermore, this cyber-threat may also establish connection to a remote location. Locations that it may connect could be the following:
