A new phishing kit has been identified that is being used to target employees of the U.S. Federal Communications Commission (FCC) and the cryptocurrency platforms Binance and Coinbase, as well as users of cryptocurrency platforms such as Binance, Coinbase, Caleb & Brown, Gemini, Kraken, ShakePay, and Trezor.

A phishing kit is a set of tools and templates that allows threat actors to conduct effective phishing campaigns. These kits are marketed on the dark web to hackers and allow them to conduct phishing campaigns without having to invest time and money into setting up their own infrastructure. Phishing kits range from simple kits that provide phishing templates and cloned login pages, to more advanced kits that are capable of adversary-in-the-middle attacks that can defeat multifactor authentication. These kits significantly lower the entry barrier for conducting phishing campaigns as they require little technical expertise. Pay a relatively small fee and sophisticated phishing campaigns can be conducted in a matter of minutes.

The new phishing kit is called CryptoChameleon and allows users to create carbon copies of the single sign-on (SSO) pages that are used by the targeted businesses. Employees are used to authenticating through a single solution, through which they authenticate with many business applications. The kit also includes templates for phishing pages to harvest the credentials of cryptocurrency platform users and employees, including pages that impersonate Okta, iCloud, Gmail, Outlook, Yahoo, AOL, and Twitter.

The phishing operation was discovered by researchers at Lookout and more than 100 high-value victims of this campaign have been identified to date. Threat actors using the kit have been contacting users via SMS, email, and phone calls to trick them into visiting a malicious site where their credentials are harvested. Users are redirected to a phishing site but before the content is displayed, they are required to pass an hCAPTCHA check. This helps with the credibility of the campaign, but most importantly it prevents automated analysis tools and security solutions from identifying the phishing site.

In the campaign targeting FCC employees, after passing the hCAPTCHA check, the user is presented with a login page that is a carbon copy of the FCC Okta page. The domain on which the page is hosted – fcc-okta[.com] – differs only slightly (1 character) from the legitimate FCC Okta login page. Login credentials alone are not normally enough to gain access to accounts as many are now protected by MFA. The captured login credentials are used to log in to the real account in real time, and the victim is then directed to the appropriate page where additional information is collected to pass the MFA checks. This could be a page that requests their SMS-based token or the MFA token from their authenticator app. Once the MFA check has been passed and the account has been accessed by the threat actor, the victim can be redirected anywhere. For instance, they could be shown a message that the login has been unsuccessful and they must try again later.

To target cryptocurrency platform users, messages are sent about security alerts such as warnings that their account has been accessed. These messages are likely to attract a rapid response due to the risk of substantial financial losses. In the campaign targeting Coinbase, the user is told they can secure their account and if they log in they can terminate suspicious devices. A similar process is used to obtain the credentials and MFA codes needed to access the account as the FCC campaign.

This is just one of many phishing kits offered on the dark web. Protecting against these phishing kits requires a combination of measures including an advanced spam filter, web filter, and security awareness training.
