Dear readers,

One of the biggest threats that we currently fight with is ransomware. Although it  already had our attention, it recently got “very popular”.  Ransomware has become one of the most successful forms of cybercrime and the 2016 quickly became the year of ransomware. Despite our skills we can still fail and become victims of its attacks. While the whole cybersecurity community  attempts to educate users , the need for better technical support is very real and ever increasing.

Current predictions don’t see the ransomware epidemic slowing down anytime soon. The situation is likely to get far worse, as more cyber criminals move into developing and deploying ransomware.

There is no perfect solution for ransomware (yet), but we hope that with this issue of Hakin9 you will learn how ransomware has evolved so far, and, more importantly, better understand what it takes to minimize the likelihood it appears in your environment, because knowledge is key in protection and prevention.

Enjoy the issue,

Hakin9 Team

How does ransomware encrypt files?

by David Share

Ransomware. The very word strikes fear in the hearts and minds of CEOs, CSOs and IT security managers alike. So much trepidation over the word is caused by the fact that it is usually mentioned after an attack has struck. The majority of the time, companies do not even consider protecting their systems from a ransomware attack until it is too late.

Machine virtualization with Proxmox

by Braier Alves

Machine virtualization is undoubtedly a very important ally for technological environments and provides economics benefits, ranging from the purchase of hardware to less expense with electric power and physical space. The best use of the resources of some servers allocated in a single machine, for example, is also one of the factors of choice of this technology, not to mention that for an administrator, the centralization of several services makes day-to-day tasks much easier.

Ransomware: Why does this cyber threat keep growing?

by TSG

Let’s go back in time by 30 years, and picture a typical business environment: The office is amass with filing cabinets, all full to the brim with documents that have been carefully separated into reams of brown folders. Heavy, thick set typewriters adorn each large dark wood desk. The filing cabinets have impenetrable looking locks guarding every drawer. The keys to each drawer are different, and each key has its own box, which is also locked. Want to find a document? It’s like the Da Vinci Code of filing cabinets. And now?

Wrath Of Ransomware

by Sumit Kumar Soni

2016 can be called the year of Ransomware. In the last year, we have seen an increase of ransomware attacks and its variants. Not only do these malware use various techniques to attack the systems/organizations, they also evolve from mere hiding files to use various encryption techniques. They innovate on infiltration techniques, as well, including systems connected to databases. Security vendors and law enforcement agencies constantly struggled to protect assets from such attackers.

What you need to know about Ransomware

by Longinus Timochenco

I aim to share a little of my experience in Information Security, Forensics and Compliance and focus on the very sensitive and emerging issue that is affecting companies and individuals all over the world. For many decades, we believed in Information Security’s technical strength, underestimating our responsibilities as IT security specialists, entrepreneurs, users and even individuals. And now we are bitterly experiencing the horror of this simple / basic technique of "Hijacking Data- Ransomware”. Strengthening Information Security and Compliance today is "necessary" and in the near future will be a must for the business world and for the simple, daily users (people). The regulations and laws on attacks, cyber crimes, etc. will be indispensable and needed more than ever.
