Browser-based cryptojacking is back as attacks spike 163%

The crypto value surge since March has been accompanied by a wave of cryptojacking attacks in line with new analysis printed by cybersecurity agency Symantec.

According to the company there was a 163% improve in browser-based cryptojacking exercise within the second quarter of 2020. Cryptojacking had beforehand been in a steep decline from March 2019 as a result of shutdown of the mining script maker, CoinHive.

Symantec factors out the rise within the final quarter coincided with a surge within the worth of Bitcoin (BTC) and Monero (XMR), two cryptocurrencies usually mined by the risk actors that depend on browser-based cryptojacking malware.

Cryptojacking noticed a excessive exercise interval from September 2017 to March 2019, changing into one of the crucial prevalent types of cyber-attacks at the moment. But in 2019, the CoinHive challenge reportedly turned economically inviable. Per the announcement, the mining service stopped its operations on March 8, 2019.
