#Cybersecurity #Frontier & #Ransomware

bitcoin ransomware

Ransomware has gained increasing attention due to the increased interest in blockchain technology.

CCN looks at How CTB-Locker Ransomware Uses #Bitcoin And #Blockchain (Read Article

"Unlike false anti-viruses that were mostly harmless and made people pay to remove non-existing threats, ransomware is a more serious challenge since it disables the computer unless a ransom is paid.

Ransomware schemes were not available five to eight years ago. #Ransomware could not accept PayPal or credit cards since those transactions are traceable. Cryptocurrencies were not an option since they were not established. Even after bitcoin emerged in 2009, it took a few years for it to build an ecosystem and achieve the adoption that made using them worthwhile.

Mass adoption of bitcoin has brought new types of criminal schemes.

Hackers are currently expanding ransomware from local computers to websites. Things like #DDoSattacks that encrypt websites and extort bitcoins as ransom have become more common."


According to TheMerkle With all of the recent focus on cyber security on the enterprise level, it is not unlikely internet criminals will start taking their attacks to the next level. Satellites present a high profile target for hackers and spreaders of malware, mainly because a satellite is usually managed remotely.

Although it is very unlikely crypto-ransomware will make an appearance in space anytime soon, it is of the utmost importance to step up cyber security as far as satellites are concerned. Nearly every country in the world relies on these machines for communication, navigations, and even the Internet. (Read Article>>)


Citing the Wired Article there seem to be two plausible scenarios when an internet criminal attacks a satellite. Either they will flood the signal to disrupt mobile phone networks – or spoof a current signal with a fake one – or they will take physical control of the satellite.

There are limits on how far commercial satellite operators can secure their communications, because telemetry #datalinks generally employ local networks, but encryption is an essential and cost-effective procedure that every operator ought to be able to use. 

It is important to establish common international standards on #cybersecurity in space now, as was done with space debris, and to share best practices to reduce cyberthreats.

Well..... Lets look back to last year "MIT's Enigma"

"Enigma’s technique works by mimicking a few of the features of bitcoin’s decentralized network architecture: It encrypts data by splitting it up into pieces and randomly distributing indecipherable chunks of it to hundreds of computers in the Enigma network known as “nodes.” Each node performs calculations on its discrete chunk of information before the user recombines the results to derive an unencrypted answer. Thanks to some mathematical tricks the Enigma creators implemented, the nodes are able to collectively perform every kind of computation that computers normally do, but without accessing any other portion of the data except the tiny chunk they were assigned."

Even more recently with DARPA looking at the potential of blockchain to securely send and receive transmissions.

#BlockchainTechnology may provide an answer to combating the very same elements who use it for extortion.
