We are aware that several individuals recently received phone calls or voicemail messages that appeared to be from an SEC phone number. The calls and messages raised purported concerns about unauthorized transactions or other suspicious activity in the recipients’ checking or cryptocurrency accounts. These phone calls and voicemail messages are in no way connected to the SEC. If you receive a communication that appears to be from the SEC, do not provide any personal information unless you have verified that you are dealing with the SEC. The SEC does not seek money from any person or entity as a penalty or disgorgement for alleged wrongdoing outside of its formal Enforcement process.
