<div>In our recent Daily Diaries, we covered lots of cybercrime gangs operating in the malware-as-a-service business model. Today we are going to cover PrivateLoader, a malware service that charges based on PPI (Pay-Per-Install) model, that is gaining popularity
delivering lots of other malware. PrivateLoader was first disclosed in 2021. Written in C++, it provides an administrative panel for cybercriminals to handle their campaigns. The platform allows attackers to configure the payload links, add geolocation locks
for the campaigns and encrypting the payloads.</div>
<div><br>
</div>
<div>The PrivateLoader malware is a Downloader that can be spread through social engineer campaigns, like spammed in phishing e-mails. When executed, it downloads the configured payload in the machine, decrypts it, and starts the next step in the attack chain.
Besides encrypting the payload, PrivateLoader contains other anti-analysis techniques, encrypting strings and obfuscating integer constants in the code.</div>
<div><br>
</div>
<div>PrivateLoader samples have been found delivering a variety of malware, such as Vidar (covered in our Daily Diary #478), RedLine Stealer (mentioned in our Daily Diary #455), SmokeLoader (also mentioned in our Daily Diary #455), LockBit (covered in our Daily
Diary #325, #339, and #440), TrickBot (covered in our Daily Diary #472), and Agent Tesla (covered in our Daily Diary #288).</div>
<div><br>
</div>
This malware is yet another example of the expansion of cybercrime malware-as-a-service business. With the evolution of those techniques, more gangs will begin to develop their own malware as a service, specializing in a single piece of the attack.
