This yr was rife with ransomware. 2021 witnessed the assault on IT software program firm Kaseya that knocked 1,500 organizations offline, the CD Projekt Crimson hack that noticed menace actors make off with supply code for video games together with Cyberpunk 2077 and The Witcher 3, and several other high-profile assaults focusing on big-name tech firms, from Olympus to Fujitsu and Panasonic.
It was additionally the yr that hackers seized world consideration by focusing on essential infrastructure, hacking American oil pipeline system Colonial Pipeline, meat-processing large JBS and Iowa New Cooperative, an alliance of farmers that sells corn and soy, to call only a few.
After the assaults led to extended shutdowns, inflated oil costs and ran the chance of meals shortages, the U.S. authorities started to take discover — after years of inaction — and scored some uncommon wins in what as soon as appeared like an unwinnable battle in opposition to the ransomware epidemic.
It started in April when the Division of Justice fashioned the Ransomware and Digital Extortion Activity Pressure. The transfer, which adopted what the DOJ described because the “worst yr” for ransomware assaults, aimed to prioritize the “disruption, investigation, and prosecution of ransomware and digital extortion exercise.” The duty drive declared its first victory two months later when the DOJ introduced it had arrested 55-year-old Latvian nationwide Alla Witte and charged her for her position in “a transnational cybercrime group” that was behind TrickBot, some of the well-known and broadly used banking trojans and ransomware instruments.
A fair larger win got here simply days later when the DOJ introduced it had seized $2.3 million in bitcoin that Colonial Pipeline paid to the DarkSide ransomware gang to reclaim its information. Since then, the U.S. authorities has supplied a reward of as much as $10 million for info that helps establish or observe down leaders of the infamous ransomware group.
On the identical time, the Treasury Division introduced sanctions in opposition to the Chatex cryptocurrency alternate for facilitating ransom transactions, simply weeks after taking related motion in opposition to the Suex crypto alternate.
The most important win for the Activity Pressure got here in October with its disruption of the infamous REvil ransomware gang. Prosecutors introduced they’d charged a 22-year-old Ukrainian nationwide linked to the gang that orchestrated the July ransomware assault in opposition to Kaseya, and mentioned it had seized greater than $6 million in ransom tied to a different member of the infamous ransomware group.
The U.S. authorities’s efforts to focus on ransomware teams this yr had been applauded by many, significantly for its tactic of following the cash. Chainalysis, a supplier of blockchain transaction evaluation software program, lauded the Treasury’s motion in opposition to Suex as a “massive win” in opposition to ransomware operators, telling TechCrunch that dismantling the mechanisms for ransomware teams to money out their cryptocurrency could be very important in slowing them down. Morgan Wright, chief safety advisor at SentinelOne, mentioned that with out eradicating the primary incentive — monetary achieve — ransomware gangs will proceed to function and broaden.
“Attackers will at all times have the benefit as a result of they don’t should comply with the foundations or the legislation. Nevertheless, there are two approaches that would critically affect the power of transitional ransomware gangs to realize their objectives — eradicating the power to make use of cryptocurrency for ransoms and machine pace responses to machine pace assaults,” mentioned Wright.
The U.S. authorities additionally supplied rewards for info on ransomware techniques, just like the $10 million bounty for info on DarkSide, and the following reward for intel on REvil. “With rewards this huge, there’s a considerable incentive for these criminals to activate each other. This motion undermines belief throughout the ransomware as a service affiliate mannequin,” Jake Williams, CTO at BreachQuest, instructed TechCrunch.
However some imagine that whereas the federal government’s actions have undoubtedly scared off some, it’s unlikely to disincentive ransomware gangs that proceed to reap the monetary rewards.
“Whereas I applaud legislation enforcement efforts to deliver these answerable for ransomware assaults to justice, the chance of apprehension and jail time merely doesn’t outweigh the big sums of cash being made by these prison teams,” mentioned Jonathan Trull at Qualys, an IT safety firm. “Sadly, the battle in opposition to ransomware is an uneven one, that means there merely just isn’t sufficient legislation enforcement assets globally to take care of the volumes and complexity of investigations wanted.”
Wright agreed, and was lower than impressed by the U.S. authorities’s exercise to date: “Arresting two folks and recovering just a few million {dollars} isn’t a victory over ransomware. That is extra of a political assertion to ’present’ one thing is being carried out about ransomware. $2.3 million isn’t even worthy of a rounding error if you have a look at the billions of {dollars} already misplaced.”
Equally, many imagine that these techniques will unlikely be sufficient to fend off the rising menace of ransomware as we enter the brand new yr, significantly as menace actors adapt their very own. Specialists imagine that the ransomware-as-a-service (RaaS) mannequin — through which operators lease out their ransomware infrastructure to others in return for a share of the ransom proceeds — will proceed to thrive in 2022, making it tougher for legislation enforcement to trace down operators.
Others count on multi-staged assault chains — the breaches that begin with a phish and result in information theft and ultimately ransomware — to turn into extra prevalent, which might allow hackers to infiltrate even essentially the most well-protected community infrastructures.
The latter will probably result in the U.S. authorities collaborating extra intently with the personal sector in 2022, in line with Trull. “Regulation enforcement alone just isn’t going to show the tide, in my view. It would should be a mixture of enforcement actions paired with devoted efforts to harden programs, develop, and operationalize backups of key information and programs, and efficient response from the personal sector.”
Whereas it’s clear that extra motion is required, the U.S. authorities is making progress. Whereas a handful of prosecutions has been mocked by some, it’s clearly had an affect — significantly on ransomware teams’ potential to promote and recruit potential companions. Within the wake of this undesirable consideration, ransomware was banned from a number of common hacking boards, resulting in one hacking group organising a faux firm to lure unwitting IT specialists into supporting its continued growth into the profitable ransomware trade.
“Ransomware gangs are much less welcome on sure cybercrime boards than they as soon as had been,” mentioned Brett Callow, a ransomware skilled and menace analyst at Emsisoft.
