The cryptocurrency exchange service ChangeNOW has announced the launch of NOW AI, a dedicated protection lab aimed at raising the security standard across all of its products, following the discovery and resolution of a vulnerability affecting one of the integrations used on its website.

The company said the flaw was found on October 15 with the help of independent security researchers and has since been fixed. While there is currently no evidence that anyone exploited the vulnerability, ChangeNOW said it cannot assume the researchers who reported it were the only ones to discover it. For that reason, the team is examining possible scenarios and warning clients about information that could have been exposed, which may include email addresses and transaction details.

ChangeNOW stressed that the vulnerability did not affect its transaction infrastructure and that customer funds were never at risk. The episode illustrates why a security response does not end with a patch: with the possibility of exposed client data left open, a fixed flaw became a public warning.

ChangeNOW Warns Users About Phishing Messages and Fake Support Emails

The company said clients should now watch out for suspicious or fraudulent messages, noting that a phony message could reference real transactions or support interactions to appear legitimate. Anyone who receives an unexpected message appearing to come from ChangeNOW is advised to verify the sender before responding, clicking any links, or providing any information.

ChangeNOW said it contacts clients exclusively via support@changenow.io and will never ask for a private key, seed phrase, or any password via email. Users are also urged to avoid downloading unexpected files or attachments and not to share verification codes with unknown contacts.

Messages that create a sense of urgency or threaten account restrictions should be verified with ChangeNOW's official support team, the company said, which also asked users to report suspicious communications so it can investigate potential impersonation attempts and protect other users from similar scams.

"People contact our support and compliance teams because they trust us with information would not share publicly," ChangeNOW said. "We also understand the responsibility that comes with that. We have no indication this vulnerability was exploited. However, we believe it is important to warn of potential risks rather than wait until there is absolute certainty."

NOW AI to Strengthen Security Across ChangeNOW Products

The company said its clients are at the center of what it does and that it continues to upgrade the protection of its products. NOW AI is intended to apply AI technology to the defensive side, spotting danger earlier and baking stronger security into ChangeNOW's offerings, especially as AI makes malicious actions easier to automate and scale.

"Today's case only made the need to move faster more obvious, and it accelerated the launch of NOW AI," the company said. The initiative reflects ChangeNOW's broader focus on proactive threat detection, faster security responses, and stronger safeguards across its services.

By implementing AI-driven defensive tools, the team aims to identify emerging risks earlier and reduce the opportunities available to attackers as malicious techniques become more sophisticated.

ChangeNOW said it will publish more details on its plans, what NOW AI covers, and how it will be used across the company's products on a dedicated page on its website soon. That page will be the first public checkpoint for what the lab covers in practice and how the rollout progresses.
