On 7 May, an American oil pipeline system that originates in Texas and carries fuel to the Southeastern United States suffered a ransomware cyber attack that impacted computerised equipment managing the pipeline.
In response, the Colonial Pipeline Company was forced to halt all of the pipeline's operations to contain the attack, triggering fuel shortages and panic buying, and forcing fuel prices to their highest since 2014, reaching almost $3 (£2.14) a gallon.
The FBI were able to identify hacking group DarkSide as the party responsible for the largest cyber attack on an oil infrastructure target in the history of the United States, but just who are they?
Here is everything you need to know about it.
What is Darkside?
DarkSide is the hacking group believed to be behind the Colonial Pipeline cyberattack.
The group first made waves in late 2020, with the DarkSide ransomware attack that encrypted user data, and withdrew other information from compromised computer servers.
Ransomware works by restricting access to a computer system until a ransom is paid to the creator in order for the restriction to be removed.
However, keen to promote a ‘Robin Hood’ image, DarkSide announced it had not – unlike other ransomware – attacked hospitals, hospices, schools, universities, non-profit organisations, or government agencies.
"We only attack companies that can pay the requested amount, we do not want to kill your business,” it said in a statement of intent. “Before any attack, we carefully analyse your accountancy and determine how much you can pay based on your net income.”
Tellingly, the ransomware also did not go after computers on which the language detected was one used in Russia and former USSR countries.
The group deals in so-called “double extortion”, in which not only is a company’s data seized and held at ransom, they are also threatened with having it published publicly if the payment requirements are not met.
Are they like Robin Hood?
A couple of months later, DarkSide claimed they had been able to extort millions of dollars from companies.
The group said it would be working to “make the world a better place”, and posted two receipts, each for $10,000 worth (£7,125) of Bitcoin donated to two charities.
“No matter how bad you think our work is," the group said in a “press release” on the dark web, “we are pleased to know that we helped change someone’s life.”
One of the charities – Children International – said it would not be keeping the donation, and though The Water Project did not comment on what it would be doing, the fact that neither charity could know exactly who donated the money or where it was stolen from meant they had no way of refunding DarkSide.
But experts said people shouldn’t be fooled by DarkSide’s seemingly charitable nature. At the end of the day, they’re still a criminal hacking group.
Brian Higgins, a security specialist at Comparitech.com, told the Guardian, “$10,000 is a paltry sum in comparison to the vast amounts of money they’ve extorted from their victims over the years… it’s hardly a grand philanthropic gesture.”
"Secondly, no credible charity is ever going to accept donations which are demonstrably the proceeds of crime.”
Is the group Russian?
DarkSide is just one of a number of hacking groups that have sought to “professionalise” a criminal industry that has cost Western nations tens of billions of dollars in losses in the past three years.
Cyber security firm Cybereason told CNBC that DarkSide is “highly professional”, offering its services to would-be customers who want to take for-profit companies down a peg or two.
“[DarkSide runs] a help desk and call in phone number for victims, and has already published confidential data on more than 40 victims,” they said.
While it’s hard to say 100 per cent where DarkSide is based, given that the group is known to avoid targeting organisations in former Soviet bloc nations, the evidence suggests a Russian base.
Their actions are also typical of known Russian hacking groups.
Did Colonial pay the ransom?
Colonial has not said whether it has paid or was negotiating a ransom.
But DarkSide did not announce the attack on its own dark web site, a lack of acknowledgement which, according to Associated Press, “usually indicates a victim is either negotiating or has paid.”
