PANews reported on February 27 that Mask Network founder Suji Yan tweeted, “6 hours ago, I turned 29, and about 3 hours ago, a public wallet carried on my mobile phone was hacked and more than $4 million in assets were stolen. All stolen transactions appear to be manual and lasted for more than 11 minutes. So either the private key was leaked on my birthday, or it could be an offline attack. I was at a private party with a dozen friends, and my phone was away for a few minutes while I went to the bathroom, etc. I believe my friends, but this is a nightmare for anyone. I have contacted SlowMist and @zachxbt, and they are assisting in the investigation and are working with relevant agencies and law enforcement. I will not make any further comments until these experts come to a conclusion. If this is really an offline attack - I hope you can face me. Cryptocurrency is not a dark forest, and I will not let it become a dark forest.”
