Global events in spam
Spam emails that mention the hottest topics in the world news agenda are a permanent feature of junk traffic. This trend has been observed for several years and is unlikely to change any time soon. Natural disasters in 2017 (hurricanes Irma and Harvey, the earthquake in Mexico) were a gift to fraudsters. “Nigerian” scammers bombarded mailboxes with messages asking for assistance in obtaining the inheritance of deceased relatives and donations for disaster victims, etc. Natural disasters were also a common theme in advertising spam and emails offering jobs and loans.
Sporting events are another favorite topic of spammers. The most popular — and most mentioned in fake giveaway messages — are major soccer competitions and the Olympics. Back in 2016 we picked up emails citing the FIFA 2018 World Cup, and the following year their number increased, with the format and content unchanged. Typically, such emails say that during such-and-such lottery, supposedly held by a well-known organization, the recipient was randomly selected among a million others as the winner of a huge cash prize. Besides money, scammers sometimes promise tickets to competitions. The details are usually outlined in file attachments using official competition and sponsor logos.
Cryptocurrencies in spam
Throughout the year we wrote that cryptocurrencies had gained a foothold in advertising spam and fraudulent mailings: all the numerous “Earn from home” schemes, financial pyramids, fake lottery wins, and phishing scams, etc., seem to have been updated and given a cryptocurrency makeover. Let’s try to systematize the various types of cryptocurrency-related spam.
As major conferences and seminars are held on blockchain technology, spammers are making increasing use of this topic for their own purposes. The seminars advertised in their mailings don’t overload users with technical details, but promise to teach them how to extract eye-watering profits from cryptocurrencies. Such mailings are relatives of “traditional” spam on the topic “How to make a killing on the stock exchange.”
A specific type of cryptocurrency fraud relates to fake “cloud mining” services. Such services hire out the mining power of their own specialized data centers. Fake sites offer similar services, but on paying up, the user receives neither mining power nor their money back. The crypto version of the classic pyramid scam warrants a special mention: the user “receives” mining income until they enlist other victims (for which there is also a reward). But sooner or later the cash flow stops, and the original investment is not repaid.
Sites masquerading as cryptocurrency trading platforms operate in a similar manner. The crucial difference between them and real exchanges is that money can only be invested, not withdrawn. Revenue usually “grows” very quickly, stimulating the user to invest more funds.
More subtle are binary options brokers (and their fake counterparts).
Another type of cryptocurrency fraud is fake services offering to exchange one currency for another, or convert it into “real” money. Scammers lure victims with favorable exchange rates, and then make off with the cash.
