Some websites received threatening emails saying the group will flood their website with an enormous amount of bot-generated web traffic and thousands of IP's in rotation with 100% bounce ratio which will make Google block their Adsence account permanently. This came as a warning from cybercriminals who demand worth $5,000 of BTC to stop the attack.
The targeted user who reported the scam to KerbsOnSecurity informed that they had detected an unusually increased invalid traffic on their recent AdSense traffic statistics. Google called the threat, a traditional way to trigger an enforcement activity against the owner by sending a massive amount of invalid traffic to their website.
The news came in the wake of Google's new policy which enstated that the AdSense team will stop displaying ads even before the invalid clicks. Google explained that according to the new policy, Google would identify high-risk activities and invalid traffic even before it happens. It will allow Google to limit ad serving in order to protect its users and advertisers further.
Taking a hard line on decentralization and cryptocurrency, last year in June, Google announced to ban all the crypto-related ads from its website. Again this year, another prominent example of hostility from Google occurred when it blacklisted the use of keywords mentioning Ethereum on its Google Ads platform. Google announced that Ethereum had been blacklisted as a keyword from Google despite the nature of service it is promoting.
