For years, the DIY (do-it-yourself) trend has been evident across the entire cybercrime ecosystem.

From the early exploits generating DIY tools that set the foundations for the upcoming “malicious economies of scale” trend to emerge, to the ongoing leaks of DIY botnet and malware generating tools that were once only available to advanced attackers, it’s never been easier to enter the world of cybercrime.

In this post, I’ll profile a novice cybercriminal’s approach to entering the profitable world of ransomware.

Email hacking for hire going mainstream – part three

Email hacking for hire going mainstream – part three

Just as we anticipated on two occasions in 2012, managed email hacking for hire services continue popping-up at publicly accessible cybercrime-friendly communities, a trend that’s largely driven by the demand for such services by unethical competition, “friends”, or current/ex-spouses.

Often pitched as “forgotten password recovery” services, they rely on social engineering, brute-forcing, and spear phishing campaigns, often leading to a successful compromise of a targeted account. Based on the number of positive vouches, the services continue receiving a steady stream off satisfied and verified customers.

In this post, I’ll profile one of the most recently advertised email hacking for hire services, specializing in hacking GMail and Yahoo! accounts, as well as email accounts using popular free Russian email service providers. How much does it cost to hack a Gmail or Yahoo! account? What about corporate email?

Let’s find out.

Cybercriminals release automatic CAPTCHA-solving bogus Youtube account generating tool

Cybercriminals release automatic CAPTCHA-solving bogus Youtube account generating tool

For years, thanks to the currently mature human-driven ecosystem offering CAPTCHA-solving as a service, cybercriminals have been persistently and automatically abusing major Web properties by undermining the “chain of trust” that these properties rely on so extensively.

Still living in a world supposedly dominated by malware-infected bots, this myopia has resulted in the rise of these managed services, rendering any recent CAPTCHA “innovations” useless since they continue relying on humans – the very species that CAPTCHA is supposed to be recognizable by in the first place.

Just how easy is it to automatically register tens of thousands of bogus accounts at, let’s say, YouTube? In this post I’ll profile a recently released tool that’s relying on API keys offered by a CAPTCHA-solving services, automating the account registration process in combination with the use of malware-infected hosts as proxies.
