Trader loses over $200K from two SIGMA Telegram bot wallets in apparent private-key leak
On 11 May 2026 a crypto trader lost over $200,000 across Ethereum, Base and BSC from two wallets created by the SIGMA Telegram trading bot; the largest losses were about $125,000 in POD on Base and $21,000 in FHE on BSC. An on-chain analyst said the drain used the private keys directly, with no token approval involved, while the victim's other wallets were untouched. The cause is unconfirmed; suggestions include fake CAPTCHA bots in Telegram, infostealer malware or a device compromise. Users of bot-generated wallets should keep balances small and never run 'verification' steps a Telegram bot asks for.
