Yandex.Browser is now able to prevent cryptojackers from concealed exploitation of its user’s devices for cryptocurrency mining purposes, as reported by Yandex to “Commersant” outlet. In order to do so, the browser will monitor and analyze user’s processor load and block malicious cryptocurrency mining scripts.
As explained by Yandex representatives, this inbuilt firewall is designed to track processor load fluctuations in the process of website browsing. Drastic load increase might be an indication of this or that website being infested with concealed cryptocurrency mining scripts. The subsequent check will determine the presence of the latter and block them while leaving website itself accessible by the users.
“Oftentimes, such kind of mining may cause negative influence on a user’s system operability. Potentially it may be capable of subduing up to 100 percent of each core’s processing power,” – the Head of desktop “Yandex.Browser” team Roman Ivanov notes.
New anti-cryptojacking firewall is compatible with all the platforms including PCs, iOS and Android mobile devices.
There may be some cases, however, when processor load cannot be a reliable indicator of cryptojacking.
“Firstly, mining scripts are capable of limiting the added load in order to be less suspicious. Secondly, false alarms are possible at the websites that use the increased processor load for legal purposes. Then, if a PC itself is outdated enough, even playing stream video way trigger false alarm,” – Alexey Malanov, firewall expert at Kaspersky Lab specified.
According to statistics provided by Kaspersky Lab, 2 700 000 Internet users fell victims to cryptojacking in 2017 worldwide, that is, 50 percent more than in 2016. The second half of 2017 alone saw cybercriminals getting away with several million dollars’ worth of cryptocurrency this way.
