Circle, a digital asset platform that powers a leading dollar-based stablecoin, USDC, has reported an information breach via a third-party service provider – Hubspot.
According to an email distributed by Circle, HubSpot has “confirmed that an unauthorized bad actor accessed certain client data from several companies, including Circle, housed on their platform after a HubSpot employee account was compromised.”
Circle notes that their internal systems were not impacted and personal information like a social security number or government ID information was not accessed. Circle adds that KYC and financial information were not stolen either.
Circle tells prospective users:
“We are notifying you so that you can take actions to protect yourself. We encourage you to monitor your accounts on a regular basis, use strong passwords and remain vigilant against phishing attempts and other suspicious activity. Phishing may be done using email, phone calls, voicemail, or text messages. In each case, the goal is to lure you into revealing confidential information such as bank account numbers, credit card information, Social Security numbers or passwords.”
