protection against ransomware

What is ransomware?

 
With this type of cyber attack, local files are encrypted so that the user no longer has access to important data or documents. Only after the payment of an individually fixed ransom amount, the affected persons have the possibility to get back their unencrypted data. Most of these payments are processed in the online currency Bitcoin. These persons and the perpetrators are very hard to trace through this method.
 
The advantage of ransomware is that entire enterprise networks can be torpedoed and paralyzed. Therefore attacks with polymorphic viruses pose a not to be underestimated threat. This applies in particular to the rapid spread of ransomware. In the following you will learn how to protect against ransomware.

How does ransomware work in practice?

Depending on the nature of the ransomware, the polymorphic viruses arrive at the target system via email. The email attachments can be camouflaged in various ways. In the case of Jaff, for example, the malware came as a supposed PDF invoice to the computers of the affected parties. Using the Java Script function, a DOC file was unpacked locally in a temporary folder. This Word file contained damaged macroviruses, through which the ransomware was downloaded to the respective systems and activated after the installation.

Why is the protection against ransomware problematic?

The challenge with polymorphic viruses goes hand in hand with the protection against ransomware. It can hit everyone – both private users, institutions and companies. The perception that mainly private users lack an adequate protection against ransomware, or the know how to protect against ransomware, is wrong. Companies are threatened by ransomware attacks, too . Even bankruptcy caused by ransomware have been seen.

 

Companies often lack an effective IT security concept that provides sufficient protection against ransomware. For a long time, the responsible persons simply underestimated the threat situation caused by ransomware, . Every second company in Germany has already been hit by a cyber attack such as espionage, data skimming or sabotage. A mature protection against ransomware is therefore reasonable, expecially to avoid extensive damage tot he company.

Ransomware Attacks – a worthwhile business model for cybercriminals

Easy to handle polymorphic viruses offer cyber criminals the possibility of automated generation of sales. Therefore some types of ransomware have been added in recent years. It is Jaff, Petya, WannaCry, Locky and Co. A business that has proved absolutely worthwhile for cybercriminals. This is due to the fact that the processing of the blackmail process can be arranged fairly simply via Bitcoin. This form of anonymous payment is very popular among cybercriminals.

 

The interaction between optimal monetization measures and the technically relatively simple implementation makes this scheme of the cyber gangsters so successful, so that they are enjoying increasing popularity. This is due not least to the lack of protection against ransomware. Because of this there still are companies that don’t have a suitable strategy for backing up their data. And even the updating of systems is not a regular task for a large number of companies. The resulting vulnerabilities ultimately lead to the tense threat situation in some companies, that are uncertain how they can protect themselves against ransomware.
