Hackers’ new target: Sweden’s Riksbank

Hacktivist network Anonymous followed through on threats to direct a cyber attack against Sweden’s Riksbank on Wednesday night in retaliation for Monday's raid on PRQ - previous hosts to The Pirate Bay and WikiLeaks.

Hackers' new target: Sweden's Riksbank

“It’s come to our attention that Swedish government raided PRQ servers in order to shut down numerous file sharing and torrent websites,” wrote the Anonymous group on English-language image board website 4chan on Wednesday.

“This has gone too far. This is unacceptable. Anonymous says this stops right now. You don’t fuck with The Internet… Today we hit their wallets hard.”

The message continued by explaining that at 10pm on Wednesday the group will carry out a Distributed Denial of Service (DDOS) attack on Sweden’s Riksbank website.

During a DDOS attack, a website is bombarded with communication requests so that the servers become overloaded and the site crashes, and late Wednesday night the Riksbank’s website was inaccessible.

“We’ve been hit by a DDOS attack,” Riksbank spokesperson Fredrik Andersson told the TT news agency around 10.30pm on Wednesday.

A spokesperson for the Swedish Civil Contingencies Agency (Myndigheten för samhällsskydd och beredskap – MSB) told the Nyheter24.se news website that several other government related websites were hit including the Courts Administration (Domstolverket), the Armed Forces, the Riksdag, security service Säpo and the website of the government offices.

Earlier in the day, the Riksbank indicated it was taking the threat seriously:

“We recognize this as a public threat against websites and we are always trying to keep the web as safe as possible. We have people who are responsible for taking care of the web and IT security,” said Charlotta Edler, spokesperson of the Riksbank to the Svenska Dagbladet newspaper (SvD).

Police are also looking into the matter.

“We’re taking this threat as seriously as we did those previous. It’s hard to judge which are most serious, but anyone handling IT should ensure that the systems can withstand threats,” said Anders Ahlqvist, an IT crimes expert with the Swedish police.

Throughout Wednesday, many university sites around the world were also hacked, including Sweden’s Uppsala and Lund universities.

Over 100 universities were hacked worldwide, according to Sweden’s national broadcaster Sveriges Television (SVT), including Cambridge in the UK and Harvard, Princeton and Stanford in the US.

The warning for Wednesday night’s attack came soon after the official website of Sweden’s National Board of Health and Welfare (Socialstyrelsen) went down on Tuesday night, although no one has so far claimed responsibility for this.

Websites for the Swedish government offices and for the Riksdag, Sweden’s parliament, were rendered inaccessible as well on Wednesday night

Major Swedish supermarket chain hit by cyberattack

One of Sweden's biggest supermarket chains said Saturday it had to temporarily close around 800 stores nationwide after a cyberattack blocked access to its checkouts.

“One of our subcontractors was hit by a digital attack, and that’s why our checkouts aren’t working any more,” Coop Sweden, which accounts for around 20 percent of the sector, said in a statement.

“We regret the situation and will do all we can to reopen swiftly,” the cooperative added.

Coop Sweden did not name the subcontractor or reveal the hacking method used against it beginning on Friday evening.

But the Swedish subsidiary of the Visma software group said the problem was linked to a mayor cyber attack on US IT company Kaseya on Friday.

Kaseya has urged customers to shut down servers running its VSA platform after dozens were hit with ransomware attacks.

A wave of ransomware attacks has struck worldwide recently, especially in the United States.

Ransomware attacks typically involve locking away data in systems using encryption, making companies pay to regain access.

Last year, hackers extorted at least $18 billion using such software, according to security firm Emsisoft.

In recent weeks, such attacks have hit oil pipelines, health services and major firms, and made it onto the agenda of US President Joe Biden’s June meeting with Russian counterpart Vladimir Putin.
