Participants in the dynamic cybercrime underground ecosystem are constantly working on new cybercrime-friendly releases in the form of malware bots, Remote Access Tools (RATs) and malware loaders.

Continuing the “A peek inside…” series, in this post I will profile yet another DIY (do-it-yourself) malware bot, available at the disposal of cybercriminals at selected cybercrime-friendly online communities.

Description of the malware bot:

“µBOT, originally named “WEBNET”, is a stable HTTP bot created for the use of herding and is perfect for collecting hundereds, and thousands of bots at an affordable price. The simple to use interface and reliable bot allows you to control your botnet with confidence, knowing your bots are safe and stable is what botnet masters need most, and this is what we provide to you with µBOT.The “µ” within in our name represents simplicity and small size, which is directly in relation with our bot itself, with a tiny size of 9kb compressed with the control from the easy-to-use control panel.”

uBot’s malware bot features include:

The AJAX- based bot is coded in VB6, meaning there are no .NET Framework dependencies. Next to the small size — ~10kb compressed, 36kb uncompressed — the malware bot offers an easy to use web-based command and control interface, positioning it as the perfect tool in the arsenal of the malicious attacker.

Webroot’s Security Team is currently in the process of analyzing the malware bot, to ensure that Webroot SecureAnywhere customers are protected for its variants.
