The US Department of State has said it will issue a reward up to $10 million (£7.4 million) to any individual who can provide it with information leading to the identification or location of any senior member of the group behind the BlackMatter ransomware tool.
An additional reward of up to $5 million (£3.7 million) will also be given to anyone who can provide information leading to the arrest or conviction of anyone involved in the distribution, or attempted distribution, of the ransomware.
The Department of State announced the initiative on Thursday, stepping up its pursuit of those who may be involved in the cyber attack on Colonial Pipeline earlier this year.
DarkSide was the malware believed to be used in the attack, which forced the US to suspend 5,500 miles of pipeline between Texas and New York, wreaking havoc on the nation's fuel supplies and spiking oil prices.
As IT Pro reported earlier this week, the BlackMatter group had confirmed it was ceasing operation following 'mounting pressure from law enforcement' and is believed to be a rebrand of the group which distributed DarkSide in the US earlier this year.
The ransomware gang issued the statement to its ransomware-as-a-service (RaaS) portal, which is used by clients, past and present, to access their copy of BlackMatter.
Experts have said that due to BlackMatter's recent success, and the lucrative nature of the business, it's likely the group will re-emerge - most likely under a different alias.
The best defence against ransomware
How ransomware is evolving and how to defend against it
"In offering this reward, the United States demonstrates its commitment to protecting ransomware victims around the world from exploitation by cyber criminals," the department said in a statement. "The United States looks to nations who harbour ransomware criminals that are willing to bring justice for those victim businesses and organisations affected by ransomware."
Following the attack on Colonial Pipeline, its CEO confirmed the company paid a $4.4 million (£3.2 million) ransom to the hackers, $2.3 million (£1.7 million) of which was subsequently recovered by the Department of Justice.
The reward is being offered under the Department of State’s Transnational Organised Crime Rewards Program (TOCRP), which has led to the convictions of more than 75 transnational criminals. The TOCRP has paid more than $135 million (£100.4 million) in rewards to date.
The rewards programme is split into two branches: one is focused on the distribution of narcotics, and the other is for transnational organised crime. Both can issue rewards of up to $25 million (£18.5 million) for information leading to the arrest and/or conviction of members of significant transnational criminal organisations.
