It looks like there’s another wave of incoming calls from unknown numbers from abroad, in this case from the Ascension Islands. If anyone tries to call them back, they will end up with a huge bill.

According to PROGET, one of its employees has noticed a call attempt from these islands. The calls are made in such a way that the recipient has no chance to answer the call because caller hangs up after a second. PROGET warns that if the potential victim does not verify the number and calls back it might cost from a couple up to a several hundred USD. In the case of PROGET, the situation is especially dangerous because employees of the company may try to call back to the unknown numbers from their company phones, thinking that a potential client has attempted to contact them.

According to Dziennik Internautów Bezpieczeństwo, the most expensive and thus the most popular contact attempts originate from the numbers beginning with +53 (Cuba), +675 (Papua New Guinea) and +225 (Cote d’Ivoire).
