Also, every time a cryptocurrency transaction occurs, the blockchain must be time-stamped and updated to verify the authenticity of the information. Prevention is always better than cure, and there are a few things users can do to prevent their machines from succumbing to a cryptojacking incident.

Threat actors, like Mallory, are motived to carry out cryptojacking attacks because mining is expensive. As we saw earlier, it currently costs about $7,000-$8,000 to mine a single bitcoin.

What’s more, the value of bitcoin can fluctuate wildly, adding financial risk. Cryptocurrencies are produced by using CPU energy to solve complex mathematical puzzles, linked to blocks of validated transactions, that are part of a digital currency program.

Be Aware Of Cyber Security News

It can also result in much higher electricity bills for companies affected. According to security researchers at AT&T, such worms can also change their scripts to run in different computer architectures, such as x86, x86-64 and aarch64. Then a cron job ensures the script will have persistence on a device or kill off the script if it gets detected. Either way, code is not stored on the victim’s device; all it does is run complex mathematical problems and sends the results to a server under the cyber criminal’s control. The second method is to place a script on a website or an ad delivered to several websites. When a victim visits an affected website or clicks on an infected ad, the script automatically runs. Cryptocurrencies are digital currencies, so the hacker only needs malware and a victim’s device to mine them.
