“Individuals who play important roles in our democracy are an attractive target for cyber actors seeking to disrupt or otherwise undermine our open and free society. That’s why the NCSC has ramped up our support for people at higher risk of being targeted online to ensure they can better protect their accounts and devices from attacks,” Ellison said.Ahead of the major election year where more than 50 countries around the world cast their vote, Ellison urged individuals eligible for the Personal Internet Protection services to sign up and to follow their guidance to bolster defenses against various cyber threats. The initiative also extends support to civil society groups facing a heightened risk of cyber threats. A new guide, "Mitigating Cyber Threats with Limited Resources: Guidance for Civil Society," which offers practical advice for individuals such as elected officials, journalists, activists, academics, lawyers and dissidents was released on Tuesday. This guide, developed by the U.S. Cybersecurity and Infrastructure Security Agency in collaboration with international partners, aims to empower high-risk civil society communities with limited resources to combat cyber threats effectively. These include customized risk assessment tools, helplines for digital emergencies and free or discounted cybersecurity services tailored to the needs of civil society organizations. The launch of the Personal Internet Protection service and the release of the guidance for civil society mark significant steps in bolstering the cybersecurity posture of individuals and organizations critical to the democratic process. By enhancing protection against cyber threats, the UK aims to safeguard the integrity of its democracy and promote collective resilience against global threats to democracy.

The Change Healthcare ransomware attack has taken a third cruel twist. A new ransomware group, RansomHub, has listed the organisation as a victim on its dark web leak site, saying it has 4 TB of “highly selective data,” which relates to “all Change Health clients that have sensitive data being processed by the company.”
The announcement follows a series of events that require some unpacking.
Change Healthcare is one of the largest healthcare technology companies in the USA, responsible for the flow of payments between payers, providers, and patients. It was attacked on Wednesday February 21, 2024, by a criminal “affiliate” working with the ALPHV ransomware group, which led to huge disruptions in healthcare payments. Patients were left facing enormous pharmacy bills, small medical providers teetered on the edge of insolvency, and the government scrambled to keep the money flowing and the lights on.
American Hospital Association (AHA) President and CEO Rick Pollack described the attack as “the most significant and consequential incident of its kind against the US health care system in history.”
The notorious ALPHV ransomware group claimed responsibility, chalking up Change Healthcare as one of a raft of healthcare victims in what looked like a deliberate campaign against the sector at the start of 2024.
ALPHV used the ransomware-as-a-service (RaaS) business model, selling the software and infrastructure used to carry out ransomware attacks to criminal gangs known as affiliates, in return for a share of the ransoms they extorted.
On March 3, a user on the RAMP dark web forum claimed they were the affiliate behind the attack, and that ALPHV had stolen the entirety of a $22 million ransom paid by Change Healthcare. Shortly after, the ALPHV group disappeared in an unconvincing exit scam designed to make it look as if the group’s website had been seized by the FBI.
ALPHV’s exit left Change Healthcare with nothing to show for its $22 million payment, a disgruntled affiliate looking for a ransom, and very possibly two different criminal gangs—ALPHV and its affiliate—in possession of a huge trove of stolen data.
Now, a month later, a newcomer ransomware group, RansomHub has listed Change Healthcare as a victim on its website.
While some have speculated that Change Healthcare has suffered a second attack, the RansomHub site itself makes the connection to the events surrounding February 21 quite clear:
As an introduction we will give everyone a fast update on what happened previously and on the current situation.
ALPHV stole the ransom payment (22 Million USD) that Change Healthcare and United Health payed in order to restore their systems and prevent the data leak.
HOWEVER we have the data and not ALPHV.
RansomHub first appeared in late February and its arrival dovetails neatly with ALPHV’s disappearance in very early March, leading some to think they are the same group under two different names.
The statement also pours water on the idea that RansomHub is a rebrand of the ALPHV group with its suggestion that “we have the data and not ALPHV.” However, any public statement like this has to be tempered by the fact that ransomware groups are prolific liars.
It’s not uncommon for affiliates to work with multiple RaaS providers, so the most likely explanation is that having lost its money to ALPHV, the affiliate that ransacked Change Healthcare has paired up with a different ransomware group.
Whatever the reason, there is no comfort in it for Change Healthcare. Having apparently already paid a ransom thirty times greater than the average demand, it now has to decide whether it’s going to pay out again.
For everyone else, it’s a lesson in how devastating ransomware can be, and how badly things can go even when you pay a ransom.

In 2023, the CL0P ransomware gang broke the scalability barrier and shook the security world with a series of short, automated campaigns, hitting hundreds of unsuspecting targets simultaneously with attacks based on zero-day exploits. The gang’s novel approach challenged a bottleneck that makes it hard to scale ransomware attacks, and other gangs may try to replicate its approach in 2024.
Big game ransomware attacks are devastating but relatively rare compared to other forms of cyberattack. There were about 4,500 known ransomware attacks in 2023, although the true figure is probably twice that. These attacks extorted more than $1 billion in ransoms in 2023, according to blockchain data platform Chainalysis.
The potential riches are enormous and there’s no other form of cybercrime that’s so lucrative, so why aren’t we seeing more attacks? It doesn’t seem to be a lack of targets, in fact the evidence suggests that the gangs are picky about who they attack. The most likely reason is that each attack takes a lot of work. Broadly speaking, an attack requires a team of people that: Breaks in to an internet-connected computer, researches the target to see if they’re worth the effort of an attack, explores their network, elevates their privileges until they’re an all-conquering administrator, steals and stores terabytes of data, attacks security software and backups, positions ransomware, runs it, and then conducts negotiations.
Doing all of this efficiently requires people, tools, infrastructure, expertise, and experience, and that seems to make it a difficult business model to scale up. The number of known ransomware attacks a year is increasing steadily, by tens of percentage points rather than exploding by thousands. This suggests that most of the people who are drawn to this life of crime are probably already doing it, and there isn’t a vast pool of untapped criminal talent waiting in the wings.
Before 2023, cybercrime’s best answer to this scalability problem was Ransomware-as-a-Service (RaaS), which splits the work between vendors that provide the malware and infrastructure, and affiliates that carry out the attacks.
CL0P found another way. It weaponised zero-day vulnerabilities in file transfer software, notably GoAnywhere MFT and MOVEit Transfer, and created automated attacks that plundered data from them. Hundreds of unsuspecting victims were attacked in a pair of short, sharp campaigns lasting a few days, leaving Cl0P as the third most active gang of the year, beating ransomware groups that were active in every month of 2023.
It remains to be seen if other gangs can or will follow CL0P’s lead. The repeated use of zero-days signaled a new level of sophistication for a ransomware gang and it may take a while for its rivals to catch up. However, the likes of LockBit—the most prolific group of them all—don’t want for resources so this is probably a matter of time and will, rather than a fundamental barrier.
There is also a question mark about how successful the attacks were. While automation allowed CL0P to increase its reach, it’s reported that a much lower percentage of victims paid a ransom than normal. However, ransomware incident response firm Coveware believes the group managed to compensate by demanding higher ransoms, earning the gang as much as $100 million.
Because of CL0P’s actions, the shape of ransomware in 2024 is in flux and organisations need to be ready. To learn more about how big game ransomware is evolving, the threat of zero-day ransomware, and how to protect against them, read our 2024 State of Malware report.
