Indeed it is. The blockchain platform may be more solid and secure, but other elements of the "crypto service" (wallet, exchanges, mining pools, mining rigs, nodes, ICO web pages, etc ... ) are open to "traditional" Internet type of hacking.
Everything can be hacked. In crptoworld, nothing is totally secure 
There are currently many hackers who want your money so do not be fooled. First of all, focus on protection and good protection of the wallet because this is the biggest problem for users.
