  • January 26, 2019 - LocalBitcoins Bitcoin Exchange 8 BTC or more

    Per the post-mortem, the still-anonymous attacker was able to breach a third-party software used by LocalBitcoins, but was quickly shut down. Interestingly, Vera claimed that six cases have been all but confirmed, contradicting the five incoming transactions on the suspicious address. This discrepancy wasn’t addressed, so it can be assumed that the hacker managed to siphon funds into another address.

    @LocalBitcoins has apparently been compromised. Users are claiming its forums were redirecting them to a login page that was a phishing website.

    An address shared on social media already has $28,000 worth of #BTC in it after tricking 5 victims. Forums are now diabled. #bitcoin pic.twitter.com/iKLyMQ0Unf

  • December 21, 2018 - Electrum wallet 200 BTC

    A scary scheme by hackers recently successfully lifted Bitcoin from Electrum wallet owners to the tune of approximately $750,000.

    The attackers added anywhere between 33 and 50 malicious servers to the Eletrum wallet network. When legitimate owners of Electrum Bitcoin wallets initiated a Bitcoin transaction after December 21, 2018, if the transaction was routed through a malicious server, the user received an error message surging the user to download a wallet app update coming from an unauthorized GitHub depository. Once they download the malicious update, the app asks the user for a two-factor authentication code, which is then used by the thief to steal the user’s funds and transfer the funds to the hacker’s Bitcoin address.

    The attacks were reportedly successful because the server messages were delivered as rich-formatted texts, which made the popup alert look authentic and conveniently provided a link for users to click on to apply the update. Following discovery of the heist, Electrum reportedly updated the Electrum wallet app so the messages urging users to download the update no longer appear in rich HTML text. Still, one of the issues with cryptocurrency is the fact that it is not protected by the government and it is unclear what, if anything, these Electrum wallet users can do to get their stolen Bitcoin back.

Of the 6.7 billion stolen yen, 2.2 billion yen — 32 percent — were Zaif funds, while 4.5 billion yen were customer funds. Zaif plans to secure a 5 billion yen loan to pay back affected customers.
