The attacks of hackers targeting cryptomonas - a process called "mining" - have grown even in Romania, where more than 240 cases have been identified, according to Kaspersky Lab.
" Attacks on software to track cryptomonas are part of a trend that we have highlighted in our predictions this year. Thus, we expect hackers to take advantage of the growing popularity of cryptomonas in 2018 and steal money from users' digital wallets, or secretly install mining tools on devices, especially mobile devices, "says a
Kaspersky Lab's research shows that the number of those affected by such attacks has already exceeded two million in 2017.
On the other hand, "if the problem is properly managed and the user's consent, some cryptomonkey mining methods may become a legitimate form of monetization for sites and / or applications that will in the meantime replace advertisements ". In other words, "users could well provide their resources in return for accessing the content available on those sites," notes Kaspersky Lab.
Such attacks are possible due to the vulnerabilities of either the website or the hosting company and are easy to do, many sites being broken and the Coinhive code being injected into the source. "In the past 30 days, we have identified 241 sites in Romania that run Coinhive on visitor computers, but research continues and probably the final number will be higher," Kaspersky Lab says.
According to researchers, such attack "is not necessarily very dangerous for site visitors, but it has unpleasant effects because it uses the resources of the devices and slows down their operation."
"To protect themselves, we recommend that site administrators use complex security solutions that include server protection, and Internet users - to maintain their upgraded security programs so they can block such scripts. We also recommend browser extensions such as uBlock Origin, Noscript, or Adblock to combat attempts to use their resources without their knowledge or consent, "said Dan Demeter, Security Researcher at Kaspersky Lab
