FacexWorm spam campaign is similar to two other Facebook Messenger spam campaigns, one that took place in late August 2017 and another in December 2017.

 

How FacexWorm spreads and infects users?


The FacexWorm infection usually infects the users through Facebook Messenger. The users receive a spam link via Facebook Messenger as the attackers spread the malicious link to all friends of the victim.

 

When the users click the spam URL, the URL redirects the user to a fake Youtube page, which tricks the user into installing a fake YouTube-themed Chrome browser extension.

 

It asks the users to play the video on the fake Youtube page which will then request permission to access and change data on the opened website.

 

In order to spread, FacexWorm establishes communication with C&C to check the propagation function. If the propagation function is activated, it performs various queries to obtain user’s Facebook account’s friends list. It then sends fake YouTube video links to the friends who are online or in idle status.

 

FacexWorm also shows up on websites whose URLs also include terms such as "eth" "ethereum" or "blockchain".

Harmful Effects of FacexWorm


The numerous malicious functions of FacexWorm are:


  1. The extension injects malicious mining codes on the webpage.
  2. It redirects users to the attacker's referral link for cryptocurrency-related referral programs.
  3. It downloads and installs malicious JavaScript from the command and control server.
  4. It adds code to Chrome browser of the users to steal login credentials from login forms. The collected credentials are sent to the servers of the FacexWorm gang.
  5. The rogue extension automatically redirects users to scam pages carrying out a cryptocurrency scam. It asks users to send a small amount of money to verify their account. This redirection occurs only when users attempt to access cryptocurrency-related websites.
  6. The extension inserts a cryptojacking mining script in the web browser.
  7. FacexWorm can also steal cryptocurrency
  8. It switches the recipient’s address to one of the address of FacexWorm extension creators for cryptocurrency transactions on trading platforms such as Poloniex, Bitfinex, HitBTC, Ethfinex, Binance, etc. This way it steals cryptocurrency.
  9. When the users try to access certain websites, FacexWorm redirects users to referral URLs. This is another way through which the malware creators are earning money via their infected hosts. The referral URL redirection has been identified for sites such as HashFlare, Binance, FreeBitco.in, DigitalOcean, and FreeDoge.co.in.
  10. It hijacks transactions in trading platforms and web wallets.
  11. It steals the victim’s account credentials for Coinhive, Google and MyMonero. Once FacexWorm discovers that the target website’s login page is loaded, it will inject a malicious function. This function sends the credentials to its C&C server when the form is completely filled and the login button is clicked.
  12. When FacexWorm notices that the user is using keywords such as “eth-”, “ethereum” or “blockchain” in the URL, or if the user is accessing any of the 52 targeted cryptocurrency trading platforms, the FacexWorm extension will redirect the users to a scam webpage and carry out a cryptocurrency scam.
  13. When the user opens the transaction page on a cryptocurrency-related website, the malicious extension locates the address typed in by the victim. It then replaces the address with another one which is specified by the attacker. This way it hijacks cryptocurrency-related transactions.
