The Instagram account of Australian fashion blogger Rozalia Russian was hijacked by an American hacker, who extorted $5,000 (£3,500) from her before handing back her credentials, according to a report in the Sydney Morning Herald.

Russian, who has more than 181,000 combined followers on her @rozalia_russian Instagram page and her Instagram online store page, knew something was amiss when fake followers started posting ads on her page, the report explains. Meanwhile, legit followers were un-following her after receiving irritating spam. Russian attempted to log in, but someone had changed her credentials.

Russian said her own IT expert traced the attack to a college student in the US, who demanded the US$5,000 (£3,500) payment when Russian called him directly. Russian said she and a travel blogger friend who was also hacked paid the ransom together.
