Hancitor is a backdoor Trojan that downloads and installs other threats, such as backdoor Trojans and spyware. It often uses spam emails for compromising its targets after they open associated attachments and enable 'advanced content,' like a Word macro. Users can update their software and scan new downloads for in-advance protection, and an advanced anti-malware product should eliminate Hancitor infections safely.
A Download by Any Means Necessary
Trojan downloaders are an often-necessary go-between for greasing the wheels of Trojan distribution that cause crimes that range from file-locking extortion to hijacking bank accounts. Some residents of this classification, however, are more long-lived than others, and Hancitor is a notably seasoned case of such a Trojan. Throughout the years, it also provides the security industry with many demonstrations of the different exploits in use for infecting victims – but, usually, always starting from the same point.
Nearly all Hancitor attacks start with an e-mail message that includes either a link to a file or an attachment, which it misrepresents as being a Paypal invoice, a delivery notification, etc. The threat actor's goal isn't only getting victims to click the file, but to enable the additional content that contains exploits for loading Hancitor. Some of the techniques that malware experts are verifying include:
- Copying a native Windows DLL file and using it for generating a new process and 'hollowing' it by injecting Hancitor's code.
- Calling the Windows API of CallWindowProc and loading shell commands.
- Using a resource enumeration function for loading the same commands.
- Hiding segments of code in an embedded image's header.
Many of these strategical advantages focus on countering the PC security industry's wares and researchers. However, some techniques, such as having the fake document set its drive-by-download code's font size to 1, orient themselves at tricking imperceptive users.
Cutting Drive-by-Downloads Off at the Knees
None of the delivery methods for Hancitor change its intended payload, which, in most attacks, focuses on either data-exfiltrating spyware or backdoor Trojans that let threat actors control your computer. Both the Pony botnet's bots and Vawtrak banking Trojans will exploit Hancitor's downloading capabilities for loading themselves onto vulnerable PCs. Their consequential attacks can include keylogging, or recording your keyboard input, form-grabbing credentials like passwords, cryptocurrency mining, or man-in-the-browser attacks that redirect you to phishing sites.
Many of the above security issues will endanger your information and bank accounts directly. Correspondingly, victims of any Hancitor infection should speak with their bank and credit card companies for additional recommendation and be ready for changing all passwords, security questions, etc. Symptoms of Hancitor infections, or its related threats, may or may not be self-evident.
Anti-malware programs of most brands should provide coverage against the document-based exploits in use here. They also should delete Hancitor while scanning your PC, although updates may be necessary for counteracting the latest versions of the Trojan, presuming any new obfuscation.
Even if you don't know it, Hancitor gets onto your hard drive with your help. Without people opening things that they shouldn't, all of its technological trickery would be in vain.
