ATHENS — The Greek police cybercrime unit tracked down and arrested a 23-year-old hacker in the capital, charging him with unlawfully accessing information systems of foreign companies with the help of accomplices still unknown, said Kathimerini.

The man, who was not identified, was said to have gotten into the phones of employees of companies based abroad through a SIM card swap, gaining access to their emails as well as other personal accounts and online platforms.

He was caught after police were informed by foreign authorities that he had hacked the accounts of at least seven foreign companies operating on the Internet, causing them some 1 million euros ($1.12 million) in damage although it wasn’t said if he had stolen that much.

In 2018, the police cybercrime team reported a 29.6 percent increase in the number of cases being investigated, mostly for fraudulent activities but with a number finding child pornography suspects.

The unit’s director Giorgos Papaprodromou told 104.9 FM that, “Most cases relate to the purchase of products such as cellphones or medicines, which are potentially dangerous and could put our fellow citizens at risk,” he said at the time.
