2026 Start of the Year, the crypto community has experienced two consecutive security storms, pushing users' anxiety levels to the peak. First, the backup vulnerability incident involving the longstanding wallet ImToken sparked widespread discussion, followed by reports of a serious vulnerability in the iOS system that allows user privacy data to be read at will. As an industry insider who has long been concerned with crypto security, I want to honestly say: this is not an accident, but rather a reflection that the overall security awareness of the user base is still at a beginner level.

Let's first look at the ImToken backup controversy. After the incident was exposed, many users began to panic: "I'm also using this wallet, could I have been affected too?" Actually, there's no need to worry excessively. The core issue here is not the wallet software itself, but users' usage habits.

Many people, for the sake of convenience, directly use the phone's built-in backup function to save wallet data. But this backup method is a full backup; if the phone is professionally forensically examined or lost, these backup data become keys in someone else's hands. Here's a practical suggestion: never rely on the phone's system backup for your core wallets, and definitely don't think about cloud backups. The safest approach is to manually record your private keys or seed phrases, then adopt a "sharding storage" strategy—split the seed phrase into 2 to 3 parts and store them separately, such as one part in a home safe, and the other parts entrusted to trusted family or friends for safekeeping.

Regarding the iOS vulnerability incident, it serves as a wake-up call for all crypto users: no system is absolutely secure. All we can do is improve our own defense levels and not completely shift the responsibility of security onto software developers.
