In their Carbis Bay communique, the G7 announced their intention to work collectively to deal with ransomware groups. Days later, US president Joe Biden met with Russian president Vladimir Putin, the place an extradition process to convey Russian cybercriminals to justice within the US was mentioned. Putin reportedly agreed in precept, however insisted that extradition be reciprocal. Time will inform if an extradition treaty will be reached. But whether it is, who precisely ought to extradited – and what for?

The downside for law enforcement is that ransomware – a kind of malware used to steal organizations’ information and maintain it to ransom – is a really slippery fish. Not solely is it a blended crime, together with totally different offenses throughout totally different our bodies of regulation, however it’s additionally a criminal offense that straddles the remit of different policing agencies and, in lots of circumstances, countries. And there isn’t a one key offender. Ransomware assaults contain a distributed community of totally different cybercriminals, typically unknown to one another to scale back the chance of arrest.

So it’s necessary to have a look at these assaults intimately to grasp how the US and the G7 would possibly go about tackling the increasing number of ransomware assaults we’ve seen throughout the pandemic, with a minimum of 128 publicly disclosed incidents happening globally in May 2021.

What we discover once we join the dots is an expert trade far faraway from the organized crime playbook, which seemingly takes its inspiration straight from the pages of a business studies manual.

The ransomware trade is chargeable for an enormous quantity of disruption in as we speak’s world. Not solely do these assaults have a crippling financial impact, costing billions of dollars in harm, however the stolen data acquired by attackers can proceed to cascade down by the crime chain and gasoline different cybercrimes.

Ransomware gangs are running riot – paying them off doesn’t help

Ransomware assaults are additionally altering. The legal trade’s enterprise mannequin has shifted in direction of offering ransomware as a service. This means operators present the malicious software program, handle the extortion and fee methods and handle the popularity of the “brand”. But to scale back their publicity to the chance of arrest, they recruit associates on beneficiant commissions to make use of their software program to launch assaults.

This has resulted in an in depth distribution of legal labor, the place the individuals who personal the malware are usually not essentially the identical as those that plan or execute ransomware assaults. To complicate issues additional, each are assisted in committing their crimes by companies provided by the broader cybercrime ecosystem.

How do ransomware assaults work?

There are several stages to a ransomware assault, which I’ve teased out after analysing over 4,000 assaults from between 2012 and 2021.

First, there’s the reconnaissance, the place criminals determine potential victims and entry factors to their networks. This is adopted by a hacker gaining “preliminary entry”, utilizing log-in credentials purchased on the darkish internet or obtained by deception.

Once preliminary entry is gained, attackers search to escalate their entry privileges, permitting them to seek for key organizational information that may trigger the sufferer essentially the most ache when stolen and held to ransom. This is why hospital medical records and police records are sometimes the goal of ransomware assaults. This key information is then extracted and saved by criminals – all earlier than any ransomware is put in and activated.

Next comes the sufferer group’s first signal that they’ve been attacked: the ransomware is deployed, locking organizations from their key information. The sufferer is shortly named and shamed by way of the ransomware gang’s leak web site, situated on the darkish internet. That “press launch” can also function threats to share stolen delicate information, with the purpose of scary the sufferer into paying the ransom demand.

Successful ransomware assaults see the ransom paid in cryptocurrency, which is tough to hint, and transformed and laundered into fiat forex. Cybercriminals typically make investments the proceeds to reinforce their capabilities – and to pay associates – in order that they don’t get caught.

The cybercrime ecosystem

While it’s possible {that a} suitably expert offender may carry out every of the features, it’s extremely unlikely. To cut back the chance of being caught, offender teams are inclined to develop and grasp specialist expertise for various levels of an assault. These teams profit from this inter-dependency, because it offsets legal legal responsibility at every stage.

And there are a lot of specialisations within the cybercrime underworld. There are spammers, who rent out spamware-as-a-service software program that phishers, scammers, and fraudsters use to steal individuals’s credentials, and databrokers who commerce these stolen particulars on the darkish internet.

They may be bought by “initial access brokers”, who specialise in gaining preliminary entry to laptop methods earlier than promoting on these entry particulars to would-be ransomware attackers. These attackers typically have interaction with crimeware-as-a-service brokers, who rent out ransomware-as-a-service software program in addition to different malicious malware.

To coordinate these teams, darkmarketeers present on-line markets the place criminals can overtly promote or commerce companies, normally by way of the Tor community on the darkish internet. Monetisers are there to launder cryptocurrency and switch it into fiat forex, whereas negotiators, representing each sufferer and offender, are employed to settle the ransom quantity.

This ecosystem is consistently evolving. For instance, a current improvement has been the emergence of the “ransomware consultant”, who collects a charge for advising offenders at key levels of an assault.

Arresting offenders

Governments and regulation enforcement companies look like ramping up their efforts to deal with ransomware offenders, following a yr blighted by their continued assaults. As the G7 met in Cornwall in June 2021, Ukrainian and South Korean police forces coordinated to arrest components of the notorious CL0P ransomware gang. In the identical week, Russian nationwide Oleg Koshkin was convicted by a US courtroom for operating a malware encryption service that legal teams use to carry out cyberattacks with out being detected by antivirus options.

While these developments are promising, ransomware assaults are a posh crime involving a distributed community of offenders. As the offenders have honed their strategies, regulation enforcers and cybersecurity specialists have tried to maintain tempo. But the relative inflexibility of policing preparations, and the shortage of a key offender (Mr or Mrs Big) to arrest, could all the time preserve them one step behind the cybercriminals – even when an extradition treaty is struck between the US and Russia.The Conversation
