In a significant crackdown against online cybercriminals, German authorities have successfully dismantled a network of fraudulent cryptocurrency investment sites that has targeted millions of unsuspecting people across Europe.

According to a press release by BaFin (Germany's financial regulatory authority), 1,406 bogus trading platforms were seized on October 3, 2025, in an operation co-ordinated with other German agencies, Europol and Bulgarian law enforcement.

Within ten days of the takedown, BaFin says that approximately 866,000 attempts to access the seized website domains were recorded - with would-be victims now greeted by a warning banner instead of the professional-looking trading platform they expected to find.

In short, a lot of people have most likely just learnt that they either have been, or have closely avoided becoming, victims of sophisticated scammers.

Criminals lure their unsuspecting victims to professional-looking fake trading platforms that promise lucrative returns on investments in cryptocurrency, stocks, and other commodities.

When victims deposit money in the online platform, they will be shown apparent profits that they have made, but the truth is that no actual trading occurs. The entire site, which may appear slick and highly-professional, is just pretending to be a trading platform - but in truth it is simply a means for the criminals to extract funds from their prey.

In tandem, scammers at call centres pressure those who engage with the fraudulent investment sites to make further "investments". Months may pass before victims eventually realise the stomach-churning truth that they have been scammed. By the time victims realise that they have fallen foul of fraudsters, their money has been laundered and is beyond reach.

In the case of the domains seized by Operation Heracles, the sites specifically targeted German-speaking individuals.

BaFin warns that the online trading fraud sites are particular dangerous because of their professional execution. It is believed that the fraudsters are using artificial intelligence to mass-produce websites with sophisticated user interfaces, detailed market data, convincing customer testimonials, and even mobile apps.

Operation Heracles follows a similar initiative in June, when authorities blocked approximately 900 domains. Since then, according to the authorities, there have been some 5.6 million attempts by users to access the blocked sites. That sobering statistic underlines just how widespread and pernicious online investment fraud has become.

Anyone considering making an online investment would be wise to look out for the following "red flags":

• Returns that seem too good to be true
• High-pressure sales tactics which demand quick decisions
• Requests for increasingly larger deposits
• Difficulty withdrawing funds

Once again internet users would be wise to remember the old adage - if something sounds too good to be true, it probably is.
