Flash Report: Phishing Ads Target Password Managers
- Phishing ads aimed at stealing password vault credentials are the latest tactic used to target password managers.
- Recent targeting of password managers has involved security breaches and credential stuffing attacks.
- Threat actors’ level of sophistication with creating phishing pages continues to evolve.
- The identified phishing pages targeting the password managers have since been removed; however, this does not abate the threat of this type of activity.
In the wake of recent breaches targeting password managers, another headache has emerged—this time targeting Bitwarden and other password managers. Over the last several weeks, ZeroFox Intelligence has reported on password managers being exploited via a security breach and a credential stuffing attack. Password managers are once again being targeted utilizing another attack vector—Google Ads phishing campaigns. These campaigns are aimed at stealing users’ password vault credentials by creating phishing pages that look very similar to Bitwarden’s or other password managers’ login sites and then capturing the user’s credentials. Adding to their perceived authenticity is that once credentials are entered, users are redirected back to the legitimate login pages.
While some users claimed the phishing sites were relatively easy to spot, others indicated that they appeared to be legitimate and were challenging to identify. The phishing pages in question have been removed since being identified. However, depending on how successful the threat actors were in capturing credentials, they are likely to employ similar tactics in the future given the potentially high return on investment if password vaults can be accessed.
- Update current master and stored passwords utilized on any password management service; while this will not change any impacts of affected breached vaults, it is a best practice for getting ahead of potential future attacks.
- Do not share passwords, and do not reuse the same password on different websites and applications.
- Enable two-factor authentication for all organizational accounts to help mitigate phishing and credential-stuffing attacks.
- Remain vigilant against potential phishing attempts.
- Exercise caution when submitting credentials on websites, ensuring that they are legitimate sites.
- If not already enabled, engage with ZeroFox for ongoing compromised credential monitoring. Immediate password changes should be implemented for any affected account.
- ZeroFox recommends remaining vigilant and denying multifactor authentication (MFA) requests not specifically triggered by logging in or requesting device enrollment. These requests are typically immediate and should not randomly appear throughout the day.
