What Is Dropper as a Service?
Dropper as a service (DaaS) refers to services offered by cyber criminals that assist with covertly distributing malware. DaaS providers enable malware developers to upload their malware, which is then installed on unsuspecting users' devices via social engineering methods and other techniques.
How Does Dropper as a Service Work?
A dropper is a type of malware program designed to install other malicious software onto a target computer. The dropper malware gains initial access, often using social engineering tactics, and then stealthily downloads additional malware payloads onto the infected device.
Dropper as a service platform provides these droppers to malware developers, sparing them the effort of creating their own stealthy installer programs. Here's how DaaS typically works:
A malware developer creates a malicious software payload they want to distribute, such as info-stealing malware, ransomware, or a remote access Trojan.
The developer uploads their malware payload to a DaaS provider.
The DaaS provider gives the developer access to their catalog of droppers - stealth installer programs designed not to raise suspicion.
The developer configures their desired dropper to covertly download and install their custom malware payload onto targets' devices.
The DaaS provider handles distributing the configured dropper through spam emails, compromised websites, fake software updates, and other infection vectors.
When unwitting users interact with the dropper, it infects their device and installs the developer's malware payload without the user's knowledge.
Why Is Dropper as a Service Used?
For malware developers, building or acquiring effective droppers requires expertise and resources. Leveraging DaaS allows them to focus their efforts on crafting the malicious payloads instead. It also provides an infrastructure for delivering the malware to victims.
Some benefits DaaS offers malware developers include:
Access to constantly updated droppers designed to evade security software
Variety of distribution methods for wide campaign reach
Dashboards for managing campaigns and tracking infection rates
Handling of infrastructure and operations for malware delivery
By making professional-grade malware delivery accessible, DaaS has lowered barriers for cybercriminals seeking to conduct effective malware campaigns with broad reach and high rates of infection.
