A Guidebook About Bitcoin Ransom

DDoS extortion is absolutely not a new hint by the hacker community, however there have been a number of new improvements to it. Notable among them is the use of Bitcoin as a method of payment. DD4BC (DDoS for Bitcoin) is a hacker (or hacker group) who has been found to extort victims with DdoS attacks, demanding payment via Bitcoin. DD4BC appears to focus on the gambling and payment processing industries which use Bitcoin.
In November 2014, reports emerged of this group having delivered a note into the Bitalo Bitcoin exchange requiring 1 Bitcoin in return for helping the site improve its protection from DDoS attacks. At the exact same time, DD4BC implemented a small-scale attack to demonstrate the exchange vulnerability to this method of disturbance. Bitalo ultimately refused to pay the ransom, however. Instead, the website publicly accused the group of blackmail and extortion as well as created a bounty of over USD $25,000 for information regarding the identities of those supporting DD4BC.
The plots have a lot of common features. During these extortion functions, the hacker:
Launches a first DDoS attack (ranging from a few minutes to a few hours) to demonstrate the hacker is able to undermine the web site of the victim.
Demands payment via Bitcoin while suggesting they are actually helping the Website by pointing out their exposure to DdoS
Threatens more virulent attacks in the future
Threatens a higher ransom as the strikes progress (cover now or pay more later)
Unprotected websites can be taken down by these strikes. A recent analysis by Arbor Networks reasoned that a vast majority of DD4BCs real attacks have been UDP Amplification attacks, exploiting exposed UDP Protocols like NTP and SSDP. From the spectrum of cyber-attacks, UDP flood through botnet is a comparatively easy, blunt assault that simply overwhelms a community with undesirable UDP traffic. These attacks are not technically complex and are made simpler with leased bones, booters, and scripts.
The most normal pattern for the DD4BC gang is to launch DDoS attacks targeting layer 3 and 4, but if this does not have the desired result, they will/can move it to layer 7, with various types of loopback strikes with post/get requests. The initial attack typically lies on a scale between 10-20GBps. This is rather massive, but often not even near the real threat.
If a business fails to meet their requests, and if that company does not migrate this attack through different anti-DDoS services, the group will typically move on after 24 hours of a continuing assault. However, you should not count on this routine to manage your cyber security strategies.
