At the Black Hat conference in Las Vegas next month Ragan and Salazar plan to reveal how they built a botnet using only free trials and freemium accounts on online application-hosting services—the kind coders use for development and testing to avoid having to buy their own servers and storage. The hacker duo used an automated process to generate unique email addresses and sign up for those free accounts en masse, assembling a cloud-based botnet of around a thousand computers.
That online zombie horde was capable of launching coordinated cyberattacks, cracking passwords, or mining hundreds of dollars a day worth of cryptocurrency. And by assembling that botnet from cloud accounts rather than hijacked computers, Ragan and Salazar believe their creation may have even been legal. Companies like Google, Heroku, Cloud Foundry, CloudBees, and many more offer developers the ability to host their applications on servers in faraway data centers, often reselling computing resources owned by companies like Amazon and Rackspace.
Ragan and Salazar tested the account creation process for more than of those services. Choosing among the easy two-thirds, they targeted about 15 services that let them sign up for a free account or a free trial. Other than mining Cryptocoins this distributed super computer could easily be used for other more nefarious purposes such as password cracking, DDoSing or doing any other large scale parallel task.
All you have to deal with is an exchange, and withdrawing your money. Ragan and Salazar created their automated rapid-fire signup and confirmation process with the email service Mandrill and their own program running on Google App Engine. A service called FreeDNS. Then they used Python Fabric, a tool that lets developers manage multiple Python scripts, to control the hundreds of computers over which they had taken possession. Usually, only the computer speed was harmed by the threat.
The Lecpetex Botnet was so sophisticated that Facebook experts alone were not able to prevent its distribution and had to request help from the police. As the authorities were striving to disable the network, the culprits were mocking them by uploading messages on several Command and Control servers. Eventually, the two Greek hackers, responsible for the crime, were apprehended and now are about to face charges.
Lecpetex is a proof that when criminals invest enough efforts in their corrupted programs, they may successfully evade detection by the traditional anti-virus programs. The only way to prevent such risks is by a specially designed anti-malware program that focuses entirely on eradicating high-level threats. It is a common sense not to open suspicious attachments or messages.
However, even experienced Internet users may be deceived by an aggressive social engineering like receiving a message from a friend with seemingly innocent picture. In such cases, a good security program would be the only difference between a completely safe computer and a remotely controlled source of income for third parties. Name required.

The EnigmaSoft Threat Scorecard is an assessment report that is given to every malware threat that has been collected and analyzed through our Malware Research Center.
The EnigmaSoft Threat Scorecard evaluates and ranks each threat by using several metrics such as trends, incidents and severity over time. In addition to the effective scoring for each threat, we are able to interpret anonymous geographic data to list the top three countries infected with a particular threat. The data used for the EnigmaSoft Threat Scorecard is updated daily and displayed based on trends for a day period.
The EnigmaSoft Threat Scorecard is a useful tool for a wide array of computer users from end users seeking a solution to remove a particular threat or security experts pursuing analysis and research data on emerging threats. Each of the fields listed on the EnigmaSoft Threat Scorecard, containing a specific value, are as follows:.
Ranking: The current ranking of a particular threat among all the other threats found on our malware research database. Threat Level: The level of threat a particular computer threat could have on an infected computer. We rate the threat level as low, medium or high. Lecpetex Botnet.
