Although the price of coins is rising, users should also beware of phishing attacks

According to the Open DNS Labs blog owned by Cisco, the rise in Bitcoin prices has also increased the risk of phishing attacks on Bitcoin wallets. As in this summer, once the price of the currency rises, the number of attacks on users will also increase. Recently, Blockchain.info was attacked by phishing, and this blog lists several fake domain names generated during the attack.

Most attacks are initiated by phishing websites. However, more and more attackers are now choosing to hack into legitimate websites and modify the website settings to create the illusion of Bitcoin wallet hosting or other attacks.

Gmail accounts targeted

Some attackers have also targeted users’ Gmail accounts to obtain their Google Ads keywords, and then used SEO (search engine optimization) to place fake Blockchain.info accounts at the top of search results.

The article also gives several examples of WHOIS domain name registrants to illustrate this process in detail.

Open DNS Labs’ IP and domain classification system was able to detect these highly evasive attack schemes for the Blockchain.info wallet, blocking them before new phishing sites were created.

The following domain name is a typical phishing attack address targeting Blockchain.info wallet:

blockchain.info-login-verification-portal-sign-in.blockchain.info.update-com-blockchainupdate-login-attempt-come.dheekshapromoters.com

Phishing attacks continue

It is generally difficult to detect problems with this type of domain name. Those dedicated Bitcoin wallet phishing websites are even more typical. Therefore, phishing attacks against online wallets are difficult to be properly resolved for the time being.

A large number of phishing websites were exposed in dheekshapromoters.com.

Open DNS Labs can usually intercept phishing websites after they are launched or even before they are created through specific algorithms. However, for some new attack methods, any algorithmic defense is futile.

According to Open DNS Labs data analysis, once the Google keyword "how to buy Bitcoin" search volume increases, it is likely to cause currency price fluctuations, and ransomware and Bitcoin wallet phishing attacks will follow.

Negative effects of rising coin prices

Bitcoin's popularity, price, and phishing attacks are closely linked. That is, the higher the price of Bitcoin, the more likely it is to trigger an attack. Obviously, ransomware viruses have little to do with the price of the currency.

The number of ransomware depends on the delivery method, not the popularity of Bitcoin. Some analysts pointed out that even if phishing attacks and ransomware viruses eventually adopt the same architecture, the initiators of the two attacks will still be different. This also explains why false advertising keywords have become the main channel for phishing attacks.
