Attackers used the original Tor code almost unchanged, disabling only updates and some extensions. Therefore, the victims do not notice that they installed fake software.

A fake anonymous browser replaces bitcoin addresses when a user tries to replenish an account.

ESET specialists discovered three cryptocurrencyWallet allegedly associated with fake Tor. The transaction amounts since 2017 on them are relatively small - only 4.8 BTC (about $ 38 thousand at the current rate). But the loss of victims of hackers can be much greater, because the browser also replaces QIWI wallets.
