The thriving cybercrime underground marketplace has a lot to offer. From DIY botnet builders, DIY DDoS platforms, to platforms for executing clickjacking and likejacking campaigns, next to drive-by malware attacks, the ecosystem is always a step ahead of the industry established to fight back.
Continuing the “A peek inside…” series, in this post I will profile yet another freely available DIY Botnet building tool – the Umbra Malware Loader.
Aiming to ensure that their malware doesn’t end up in the hands of vendors and researchers, cybercriminals are actively experimenting with different quality assurance processes whose objective is to increase the probability of their campaigns successfully propagating in the wild without detection.
Some of these techniques include multiple offline antivirus scanning interfaces offering the cybercriminal a guarantee that their malicious program would remain undetected, before they launch their malicious campaign in the wild.
In the wild since 2006, Kim’s Multiple Antivirus Scanner is still actively used among cybercriminals wanting to ensure that their malicious software is pre-scanned against the signature-based scanning techniques offered by multile antivirus vendors.
Let’s review Kim’s Multiple Antivirus Scanner, and discuss when it’s an important tool in the arsenal of the malicious cybercriminal spreading malware for profit.

With the even decreasing prices of underground tools and services, thanks to the commoditization of these very same market items, the price for renting a botnet, or purchasing access to already infected hosts, is constantly decreasing.
Although the majority of cybercriminals are actively exploiting end and corporate users while using client-side vulnerabilities in outdated third-party applications and browser plugins, there’s a separate branch of cybercriminals who specialize in delivering their payload using nothing else but good old fashioned social engineering attacks.
Following my previous post Inside a clickjacking/likejacking scam distribution platform for Facebook, in this post I will profile AnonJDB – a Java based malware distribution platform for drive-by downloads.

How would you convert Facebook users into slaves participating in clickjacking and likejackings scams, next to using them to spamvertise your latest event promotion message?
Presumably by using one of the clickjacking/likejacking distribution platforms promising 100 slaves per day that I will profile in this post.

With DDoS extortion and DDoS for hire attacks proliferating, next to the ever decreasing price for renting a botnet, it shouldn’t come as a surprise that cybercriminals are constantly experimenting with new DDoS tools.
In this post, I’ll profile a newly released DDoS bot, namely v2 of the Cythosia DDoS bot.

Malicious attackers quickly adapt to emerging trends, and therefore constantly produce new malicious releases. One of these recently released underground tools, is the PickPocket Botnet, a web-based command and control interface for controlling a botnet.
Let’s review its core features, and find out just how easy it is to purchase it within the cybercrime ecosystem.

Just how easy is it to hack someone’s email nowadays? Very easy as the process is offered as a managed service within the cybercrime ecosystem.
Over the past couple of months, I have been monitoring an increase in managed email hacking services. These services basically offered everyone the ability to claim someone else’s email through email hacking performed on behalf of the vendor. Such services have been circulating in the wild since early 2008. Shall we take a peek at their latest market proposition?
Let’s profile a managed email hacking service offering to hack Gmail and Yahoo accounts.
