Cybercrime industry has a fervent creativity and new products are daily offered in the underground. I desire to close this week with a look to the offer on the black market speaking of brute-forcing applications and related efficiency. I discussed in past articles the need of Internet users, government and private entities, to protect their assets in the cyberspace adopting strong authentication processes, unfortunately users continue to use weak defense mechanisms and passwords easy to discover and shared across multiple Web services. These wrong habits expose the users to various categories of attacks such as brute force and social engineering. The underground market continues to release tools to advantage and automate these cybercriminal offensives.
Brute-forcing attack technique is still considered one of powerful options for attackers, it is an efficient and effective tactic to compromise web services and resources exposed on the internet. Recently services providers CloudFlare and HostGator published an alert of a massive attack being launched against WordPress blogs all over the Internet, the warning is related to a massive brute-force dictionary-based attack that could expose the password for the ‘admin’ account of every WordPress site. The strength of these attacks is in the computational capabilities recruited by cyber criminals thanks to the control of huge botnets.
But a cyber attack for a criminal is an investment for maximize the profits and botnet recruiting could be also an expensive activity that’s why criminals are looking with interest to the possibility to rent them for a limited period of time paying to other cyber criminals for the services used, we have called this model MaaS (Malware as a Service).
It must be considered that the offer of cybercriminals on the black market provides valid alternatives to these tactics. The brute.forcing tactic is getting largely replaced by other, more efficient, evasive and cost-effective approaches to compromise as many Web sites as possible
Dancho Danchev profiled a recently released a WordPress/Joomla brute-forcing and account verification tool, following some sample screenshots of the Web-based tool:
“This tool is just the tip of the iceberg on an ever-green market segment within the cybercrime ecosystem that continues to push new releases capable of launching brute-forcing attacks against any given Web property ” said Danchev.
The Web-based tool is able to use 200 simultaneous connection attempts and it can test up to password combination per second.
Has highlighted by Danchev in the underground the offer of similar tools is very articulate, brute-forcing tools are very diffused especially among the small gang of criminals and IT professionals that use them for testing purposes.
Despite the sold of new tools is the demonstration of the interest in brute-forcing attacks of cyber criminals there are various considerations that must be made when we discuss on the efficiency of the brute force tools, the factors that will probably cause the demise brute force tools are:
Brute-forcing techniques are one of the numerous weapons in the arsenal of cyber criminals but many other sophisticated and efficient tools are conquering the scene.
