Recently, AURORA Mobile Limited (NASDAQ: JG) (“Aurora” or the “Company”) has been made aware of fraudulent activities conducted by malicious actors through a fake website impersonating the official EngageLab platform (fake URL: https://01k4gnpj9arn3wc3kmedz474n3.engagelabonkings.com/h5/). These criminals have been posting recruitment information on social media platforms (such as Facebook) to carry out scams, which have unfortunately resulted in financial losses for multiple users. We hereby issue the following official statement:

The only official website of EngageLab, a subsidiary of Aurora Mobile, is:
https://www.engagelab.com

Any other websites claiming to be associated with EngageLab are fraudulent and have no affiliation with our company. All content on such sites is unauthorized and invalid.

Please also note that the only official business email address for EngageLab is:
sales@engagelab.com

We strongly advise all users to carefully verify the source of any email claiming to be from EngageLab. Do not trust emails from other domains or unverified addresses.

We have reported this matter to the relevant law enforcement authorities, and an investigation is currently underway.

We strongly advise the public to remain vigilant and exercise caution to avoid potential risks. If you encounter any suspicious websites or activities, please verify information through our official channels and report any fraudulent behavior to local law enforcement authorities immediately.
