VERY IMPORTANT

Malwarebytes has been closely monitoring the situation involving the continued attacks against users of the popular Electrum Bitcoin wallet. Initially, victims were being tricked to download a fraudulent update that stole their cryptocurrencies. Later on, the threat actors launched a series of Distributed Denial of Service (DDoS) attacks in response to Electrum developers trying to protect their users. Since their last blog, the amount of stolen funds has increased to USD $4.6 million, and the botnet that is flooding the Electrum infrastructure is rapidly growing. Case in point, on April 24, the number of infected machines in the botnet was just below 100,000 and the next day it reached its highest at 152,000, according to this online tracker. Since then, it has gone up and down and plateaued at around the 100,000 mark.
