Hackers demand R1-billion after mass extortion attack – SA firms targeted

hacker security 2156 1120 1 - Hackers demand R1-billion after mass extortion attack – SA firms targetedHackers suspected to be behind a mass extortion attack that affected hundreds of companies worldwide late on Sunday demanded US$70-million (R1-billion) to restore the data they are holding ransom, according to a posting on the dark Web.

The demand was posted on a blog typically used by the REvil cybercrime gang, a Russia-linked group that is counted among the cybercriminal world’s most prolific extortionists.

The gang has an affiliate structure, occasionally making it difficult to determine who speaks on the hackers’ behalf, but Allan Liska of cybersecurity firm Recorded Future said the message “almost certainly” came from REvil’s core leadership. The group has not responded to an attempt to reach it for comment.

REvil’s ransomware attack, which the group executed on Friday, was among the most dramatic in a series of increasingly attention-grabbing hacks.

The gang broke into Kaseya, a Miami-based information technology firm, and used their access to breach some of its clients’ clients, setting off a chain reaction that quickly paralysed the computers of hundreds of firms worldwide.

An executive at Kaseya said the company was aware of the ransom demand but did not immediately return further messages seeking comment.


About a dozen countries were affected, including South Africa, according to research published by cybersecurity firm ESET.

In at least one case, the disruption spilled out into the public domain when Swedish Coop grocery store chain had to close hundreds of stores on Saturday because its cash registers had been knocked offline as a consequence of the attack..

Earlier on Sunday, the White House said it was reaching out to victims of the outbreak “to provide assistance based upon an assessment of national risk”.

Those hit included schools, small public-sector bodies, travel and leisure organisations, credit unions and accountants, said Ross McKerchar, chief information security officer at Sophos Group.

McKerchar’s company was one of several that had blamed REvil for the attack, but Sunday’s statement was the group’s first public acknowledgement that it was behind the campaign.

Ransom-seeking hackers have tended to favour more focused shakedowns against single, high-value targets like Brazilian meatpacker JBS, whose production was disrupted last month when REvil attacked its systems. JBS said it ended up paying the hackers $11-million.

Liska said he believed the hackers had bitten off more than they could chew by scrambling the data of hundreds of companies at a time and that the $70-million demand was an effort to make the best of an awkward situation.

“For all of their big talk on their blog, I think this got way out of hand,” he said.  — Reported by Raphael Satter, (c) 2021 Reuters
