The apparent downfall of REvil, one amongst essentially the most prolific and harmful ransomware gangs of most up-to-date years, following a bunch of raids by Russian authorities has naturally been welcomed within the safety neighborhood. But this sense of reduction ought to be tempered with the almost obvious recordsdata that the takedown would not point out the ransomware threat is any closer to passing, or that the public narrative in regards to the waste of REvil is totally as it seems to be.
What we are in a position to teach for sure is that the killing blow in opposition to REvil became once struck on Friday 14 January 2022, when brokers of Russia’s FSB assert safety carrier, working alongside the Investigations Department of Russia’s Ministry of Inner Affairs, conducted raids in Moscow, St Petersburg, and Lipetsk – a small metropolis about 420 kilometres south of Moscow.
The FSB stated the muse for the activities became once the “charm of the competent US authorities” which had shared with it particulars of REvil’s chief and his involvement in ransomware attacks.
The agency stated it had established the “plump composition” of the REvil gang and totally documented the extent of its activities. It accused them of having developed malicious instrument, organised the theft of funds from bank accounts exterior Russia, and cashing out their features.
The FSB raided 25 addresses linked to 14 members of the REvil gang and recovered extra than 426 million rubles, in conjunction with $600,000 and €500,000 in cryptocurrency, linked crypto wallets, computing instruments, and – as has turn out to be commonplace in such raids – a name of luxurious vehicles.
Therefore, eight of these arrested had been charged with crimes below Fragment 2 of Article 187 of Russia’s Prison Code, which relates to the illegal circulation of formulation of price. Russian news agency TASS named two of these contributors as Roman Muromsky and Andrey Bessonov. Per Reuters, Muromsky became once identified as an online page developer specialising in small industry sites.
Greedy goofball guys
Ziv Mador, vice-president of safety learn at Trustwave Spiderlabs, spends his working days exploring the darkish web, which he describes as a “window into the soul” of the cyber prison neighborhood. He says that within the times for the reason that “unparalleled” FSB action, Russia-primarily based cyber criminals earn turn out to be terrified that time is up and there is nowhere left for them to cloak.
On the waste of 2021, Mador printed learn that pointed to a stage of situation already taking shield among some Russia-primarily based cyber criminals, who were shy that the Russian authorities were actively searching them down. This has now escalated into fright.
“We’ve considered different responses on their boards since Friday, and so that they’re very sad,” Mador tells Computer Weekly. “A pair of of them are vexed. That sense of safety they extinct to earn from working in Russia – which became once regarded as as a roughly exact haven for them – not anymore.”
In the previous, Mador explains, many cyber criminals working out of Russia had managed to wriggle out of any correct grief they’d well perchance moreover want turn out to be embroiled in – by paying bribes, as an instance – but given the FSB acted on the muse of US requests, it is miles now sure to them that the action in opposition to REvil became once signed off at the very top stage – that’s to teach, by Vladimir Putin.
In varied words, says Mador, Russian cyber criminals are working out of alternatives and hope. Some are suggesting destroying the proof of their heists, paper trails, chat logs and plenty of others. Others are talking in regards to the different of getting out of Russia altogether, with seemingly exact havens in conjunction with China, India, countries within the Heart East and even, for reasons mystifying to anyone with a passing figuring out of the cyber safety industry, Israel.

“In a single amongst the feedback, one amongst them reminds everyone how hard stipulations in Russian prisons are, he even stated it’s better to be in a US jail than a Russian jail. So they know that if they tear to detention center, it’s going to be truly hard, and it scares them,” says Mador.
There is also madden directed at REvil itself, with one infected darkish web dialogue board user calling them “greedy goofball guys” who attacked “indiscriminately without figuring out”. One other stated: “It became once needed to think sooner than hiking and encrypting multibillion-buck corporations, colleges, states. With whom did they dare to compete?”. A third dialogue board poster mused: “Being a movie basic particular person in our industry is a extremely terrible belief.”
“A pair of of them are criticising the REvil team because they earn they went too excessive profile and focused very highly effective corporations. Must it is seemingly you’ll well moreover earn got this kind of colossal affect, you map your self a goal, which is precisely what came about,” says Mador.
Tickled days are right here again
The collaboration between the US and Russia on bringing REvil to heel is, in the beginning look, welcome after years of hostility between the 2 powers on cyber and varied matters, but it’s potentially too early to teach whether or not the arrests establish a precedent for future cooperation, as Bert Steppé, senior researcher at F-Steady’s Tactical Defence unit, aspects out.
Steppé foresees two eventualities – one where the arrests were a one-off, and the many where they enact herald the muse of a longer-term cooperation between the US and Russia on cyber disorders. “I’m hoping it’s the latter, since I mediate it’s the completely formulation to take care of well-organised cyber crime gangs,” he says.
Both formulation, it’s potentially most efficient not to shield your breath for peace to ruin out. “Arrests by the Russian assert for perpetrators of global cyber crime is largely unparalleled,” says Toby Lewis, head of threat analysis at Darktrace. “While this might occasionally well perchance moreover counsel a landmark turning point in global effort to counter ransomware…it would perchance perchance be too early to keep in mind this the start up of better cooperation, comparatively than momentary political manoeuvring.”
ThycoticCentrify’s chief safety scientist and advisory CISO, Joseph Carson, is hasty to position the boot into talk of a virus of peace and cooperation between Russia and the US. “We’re in a cyber frigid battle correct now. That’s a reality. Cyber is a weapon that has been extinct,” he says.
Wwith the regional geopolitical situation in Japanese Europe final highly unsafe and unstable in regards to ongoing Russian aggression in opposition to Ukraine, some commentators earn speculated on a link between the FSB’s actions and the fractious negotiations between Moscow and Washington DC.
Present that the previous week has also considered concerted Russia-backed cyber attacks in opposition to key Ukrainian authorities targets, even supposing these actions are not linked to any identified ransomware gangs.
So would perchance well perchance the REvil arrests be an strive to sweeten the American citizens over Ukraine, or distract from the disaster? Carson concedes that while the timing would perchance well perchance moreover raise an eyebrow, it’s almost absolutely one thing else.
“Must you’ve got this kind of political situation correct now in Ukraine, alongside with focused cyber attacks in opposition to Ukraine, after which around the same time the takedown of a well-identified, notorious ransomware gang, it is seemingly you’ll well’t support but map assumptions that the timing is hooked up [and] barely plenty of oldsters are making an strive to map connections. But I’m not sure it is miles hooked up,” he says.
Carson draws on the identified connections between excessive-profile cyber crime gangs and assert-backed APT groups, which earn within the previous grew to turn out to be out to be carefully linked, to counsel that what truly motivated the FSB action became once truly an strive to raise Russia’s contain cyber mercenary forces below control.
“It’s not that they [Russia] are taking a stance on ransomware – it’s that they’re showing the many ransomware groups that they must end in line. Operate, but don’t earn caught, don’t earn your excessive infrastructure hacked, don’t tag excessive data about connections and associations,” he says.
A blow to ransomware gangs
That isn’t the waste of excessive-profile ransomware gangs, even supposing we would perchance well perchance moreover tentatively phrase forward to a duration of retrenchment as cyber criminals figure out what to enact next.
F-Steady’s Steppé says: “I believe that these gangs are going to be extra cautious about their targets, and [will] refrain from attacking anything that would perchance well perchance potentially establish off a colossal affect, as an instance Colonial Pipeline, or entice many of media attention, as an instance Kaseya, till it’s sure whether the REvil arrests are a one-time element or not. So, sure, I feel it’s too early to inform what the longer-term affect will more than seemingly be.”
Lewis at Darktrace says: “Arrests we earn considered beforehand earn had a tight tactical affect in opposition to particular person groups, however the thriving market for prison products and services, and an ever-growing checklist of groups enticing in ransomware, formulation that the affect via arrest is on the total completely a momentary respite.”

“I don’t think it’s a celebrated victory. There are many of further prison groups available,” provides ThycoticCentrify’s Carson, who aspects to the choice of cyber prison groups that earn emerged within the previous 12 months on my own, which has outpaced, by some margin, the number that had been taken down. “I don’t think we’re lowering the choice of gangs available, even supposing we are in a position to be creating different smaller ones.”
One fascinating predicament for victims is the possibility that the FSB has seized and ought to begin a grasp decryption key – this kind of key is already available from Bitdefender, but isn’t going to work for every sufferer.
Lewis says the existence of this kind of key, or who has it, is aloof an unknown quantity. “Cyber safety mavens and victims of REvil alike will more than seemingly be eagerly expecting whether the FSB were ready to rob the grasp key pair which would perchance perchance gain a method to decrypting your complete recordsdata REvil earn beforehand stolen,” he says. “It’ll even be a inquire of which contemporary victims who would perchance well perchance moreover want been in negotiations with REvil at the time of their arrests will more than seemingly be fervent to earn answered.”
One element is for obvious, these ransomware gangs that haven’t been vexed straight will swiftly phrase to replace up their ways, ways and procedures (TTPs).
“For the safety mavens available, the reality is the subsequent criminals are waiting to pounce. The next attackers are available and so that they’re going to earn extra effective ways and further winning ransomware instrument,” says Carson. “Prison groups be taught from the mistakes of the previous and so that they evolve to ensure that they’re winning at some point soon.”
In the arriving months, Carson highlights a name of eventualities that will pan out within the prison underground consistent with the REvil takedown, one being that ransomware gangs – wary of involving the penalties of REvil’s colossal heists – will look extra control over who their companions and pals goal. It’ll spur the continuing building of the ransomware-as-a-carrier subscription model, with original lines that would perchance well perchance even embody ‘allow’ and ‘inform’ lists of targets of their code.
For CISOs and their groups, the core advice for now remains to point of interest on resilience within the face of the anticipated evolution of ransomware, and notably deploy match-for-motive backup suggestions which would perchance moreover be examined and prepared for ransomware attacks, in dispute that a situation where it is seemingly you’ll well moreover earn got to keep in mind paying a ransom is shunned, and which is able to enhance recordsdata swiftly and successfully.
While this would not resolve the double extortion situation of data leakage, it’s a step within the categorical direction and ought to point out the inequity between a minor anxiousness and a basic incident.
