There are a lot of reports regarding various vulnerabilities, ransomwares and malwares which are used by hackers to somehow acquire and mine cryptocurrency. Imperva Incapsula has been inspecting the attacks, and reportedly came across the “Kitty” malware, which is an advanced Monero cryptocurrency miner, utilizing a “webminerpool”, an open source mining software for browsers.

According to the information published on Imperva Incapsula, when the Kitty bash script is executed, a PHP file named “kdrupal.php” is written to the infected server disc.

The attacker reinforces their foothold in the infected server and guarantees dominance using a backdoor independent of the Drupal vulnerability. Next, the script registers a time-based job scheduler (“cronjob”) which periodically re-downloads and executes a bash script from a remote host, every minute, giving the attacker the ability to re-infect the server or quickly change or push updates to the infected servers under their control.

Argo to Report on Mining Profitability Increase in Q2

It was also reported that by the end of June, company owns about £ 3 million in crypto assets, which is 7.7% higher than expected

The British mining company Argo Blockchain published a financial report for the second quarter of 2019, according to which its revenues increased significantly in the second quarter, exceeding its own expectations.

So, in comparison with the previous report, published in early June, the income from mining Argo Blockchain increased by 24%. The increase in profitability from mining at the same time turned out to be proportional to the increase in the Bitcoin price observed during the recent period.

The Company now expects to generate 161 BTC, or GBP1.38m of cryptoassets, in June based on a BTC price of $10,817.16 USD as of 30 June 2019. This is an increase of approximately 101% from the Company's May mining results and represents a mining margin of roughly 81%. The Company considers that this demonstrates that the Company is one of the most efficient miners in the market.

Argo Blockchain also said that as of the end of June, the company owns about £ 3 million in cryptocurrency assets, which is 7.7% higher than expected.

Also Argo Blockchain intends to expand its activities. In particular, the company plans to deploy another 2500 miners in Quebec by the end of the third quarter, which is also expected to significantly increase revenues.

Our better-than-expected mining performance reflects both improving industry conditions as well as Argo's business strategy, which has enabled it to rapidly ramp up operations and thereby take full advantage of the upturn. As a result, we enter the third quarter with a strong momentum to deliver further growth and improving mining efficiency.
