DragonForce ransomware group has been actively exploiting vulnerabilities in SimpleHelp, a remote monitoring and management (RMM) software, to target managed service providers (MSPs) and their customers. This attack serves as a stark reminder of the supply chain risks inherent in relying on third-party software, particularly RMM tools which, if compromised, can grant attackers widespread access to numerous client systems. Sophos researchers uncovered that the DragonForce operator chained three specific SimpleHelp flaws, identified as CVE-2024-57727, CVE-2024-57728, and CVE-2024-57726, to breach an MSP. This breach resulted in data theft and the subsequent deployment of ransomware across the MSP's customer endpoints, causing significant disruption and potential financial losses.
The vulnerabilities exploited by DragonForce allowed the attackers to perform several malicious actions. CVE-2024-57727 enabled unauthorized remote attackers to download arbitrary files, including server configuration files containing sensitive secrets and hashed user passwords. CVE-2024-57728 permitted admin users to upload arbitrary files, leading to potential arbitrary code execution on the host. Furthermore, CVE-2024-57726 allowed low-privilege technicians to create API keys with excessive permissions, potentially enabling them to escalate privileges to the server administrator role. All of these vulnerabilities were present in SimpleHelp's remote support software version 5.5.7 and earlier, highlighting the critical importance of promptly applying security patches. The DragonForce attack on the MSP via SimpleHelp illustrates a growing trend of cybercriminals targeting RMM and other remote tools to facilitate software supply chain attacks. By compromising a single MSP, attackers can gain access to a large number of downstream customers, amplifying the impact of their attacks. Security experts warn that MSPs must prioritize the security of their RMM software, including implementing robust patch management processes and closely monitoring for suspicious activity. This incident underscores the need for a proactive and vigilant approach to cybersecurity to mitigate the risk of ransomware and other threats exploiting channel vulnerabilities. Recommended read:

Marks & Spencer (M&S) has confirmed that customer data was stolen during a recent cyberattack, with the ransomware group DragonForce claiming responsibility. The retail giant has initiated a mandatory password reset for all customers as a precautionary measure following the breach. The attack, which has shaken the UK retail sector, also affected other major retailers including the Co-operative Group (Co-op) and Harrods.
The stolen data includes customer names, dates of birth, home and email addresses, phone numbers, household information, and online order histories. However, M&S assures customers that the compromised information does not include usable card or payment details, or account passwords. The company is working with external experts to secure its systems and has reported the incident to the relevant government authorities and law enforcement agencies. Initially reports linked Scattered Spider to the attack, it has now been claimed that DragonForce are responsible. DragonForce, a relatively new Ransomware-as-a-Service (RaaS) group, has emerged as a significant threat, initially framing itself as a pro-Palestinian hacktivist collective before shifting to profit-driven operations. They operate by leasing their ransomware to affiliates, who then carry out the attacks, with the developers taking a cut of the ransom payments. DragonForce has been targeting high-profile UK retailers, deploying ransomware to encrypt networks, disrupt online orders and payment systems, and threaten the public release of stolen data.

Scattered Spider, a sophisticated hacking collective known for its social engineering tactics, has allegedly breached Marks & Spencer by targeting the company's IT help desk. The cybercriminals reportedly duped an IT help desk employee into resetting a password, which then granted them access to internal networks. This breach is said to have disrupted M&S's online operations, leading to the temporary suspension of online orders, as reported between April and May 2025. Scattered Spider, also known as UNC3944, Octo Tempest, and Muddled Libra, has become prominent for using social engineering to exploit corporate service desks.
This attack on Marks & Spencer is part of a broader trend impacting UK retailers. The National Cyber Security Centre (NCSC) has issued warnings to organizations, urging them to be wary of phony IT helpdesk calls. Other retailers such as Co-op and Harrods have also been linked to attacks resulting in stolen member data and crippled payment systems. Any organization with a service desk is theoretically vulnerable to these low-tech, high-impact tactics employed by Scattered Spider and similar groups. Scattered Spider is believed to be composed of young US and UK citizens who are part of a collective known as "The Comm," an underground community of English-speaking criminals that communicates and coordinates using social media platforms like Discord or Telegram. While five users associated with Scattered Spider, including the alleged leader, were detained in the first half of 2024, the complete composition of the group remains undetermined. After a period of relative silence following these arrests, Scattered Spider has resurfaced with this latest string of attacks on UK retail brands, prompting renewed cybersecurity concerns.

UNC3944, a financially motivated cyber threat actor also known as Scattered Spider, has evolved from primarily conducting SIM swapping operations to focusing on ransomware and data extortion. Initially, UNC3944 targeted telecommunications organizations to facilitate SIM swaps, but since early 2023, they have shifted their focus to a broader range of industries, deploying ransomware and stealing data for extortion purposes. This transition marks a significant escalation in their tactics and impact, affecting sectors such as technology, financial services, business process outsourcing (BPO), gaming, hospitality, retail, and media & entertainment. The group has been observed conducting targeted waves of attacks against specific sectors, indicating a strategic and adaptable approach to their operations.
Despite law enforcement actions in 2024 that led to a temporary decline in UNC3944's activity, experts caution that their established connections within the cybercrime ecosystem suggest a strong potential for rapid recovery. This could involve forming new partnerships, adopting new tools to evade detection, or shifting strategies to circumvent security measures. Recent reports have indicated the use of tactics consistent with Scattered Spider in attacks against UK retail organizations, involving the deployment of DragonForce ransomware. Furthermore, the operators of DragonForce have reportedly taken control of RansomHub, a ransomware-as-a-service (RaaS) platform where UNC3944 was previously an affiliate after the shutdown of ALPHV (Blackcat) RaaS. The retail sector has emerged as an increasingly attractive target for threat actors like UNC3944. Data from tracked data leak sites (DLS) reveals that retail organizations accounted for 11% of DLS victims in 2025, a notable increase from 8.5% in 2024. This trend is attributed to the large quantities of personally identifiable information (PII) and financial data typically held by retail companies, combined with their susceptibility to business disruption. The potential for significant financial losses resulting from ransomware attacks further incentivizes these companies to pay ransom demands, making them lucrative targets for financially motivated cybercriminals.

The Co-op has confirmed a significant data breach following a cyberattack carried out by the ransomware group DragonForce. The attackers claim to have stolen sensitive data from current and former Co-op members, including names and contact details. While financial information and passwords were not compromised, the breach impacts a substantial number of individuals signed up for the Co-op's membership scheme, with DragonForce claiming access to the private information of around 20 million people. The NCSC is working with The Co-op to understand the full scope of the incident and provide expert advice.
DragonForce gained initial access to Co-op's IT networks by exploiting a vulnerability in internal communication systems, such as Microsoft Teams. They then exfiltrated large volumes of customer and employee data, using the stolen information to demand a ransom payment. Screenshots of extortion messages sent to Co-op's head of cyber security via an internal Microsoft Teams chat were shared with the BBC as proof of the breach. In response, the Co-op has implemented immediate security measures, including verifying meeting participants and requiring cameras to be turned on during calls. The attack on Co-op is believed to be part of a broader campaign targeting major UK retailers, with similar incidents recently affecting Marks & Spencer and Harrods. These attacks are linked to affiliates of the DragonForce ransomware group, believed to be part of the Scattered Spider cybercrime community. This group is known for employing aggressive extortion tactics and sophisticated entry methods such as SIM swapping and MFA fatigue. The Co-op is currently rebuilding its Windows domain controllers and strengthening its defenses in collaboration with Microsoft DART and KPMG. Recommended read:

UK retailers have been targeted by a series of cyberattacks, prompting a national alert from the National Cyber Security Centre (NCSC). These attacks involved ransomware tactics and social engineering, leading to system disruptions and data breaches at several high-profile retail chains. The NCSC has issued a wake-up call to organizations, urging them to bolster their cybersecurity posture amid the growing threats. Attackers have also been impersonating IT helpdesks, tricking employees into handing over login credentials and security codes to gain access to company systems.
Marks & Spencer, Co-op, and Harrods have all been targeted recently, with DragonForce, an infamous ransomware group, claiming responsibility for the disruptions. The initial breach occurred at M&S, followed by an attempted hack at Harrods just days after the Co-op breach. Co-op revealed that its recent breach was more serious than initially reported, with a significant amount of data from current and former customers stolen. Attackers stole names and contact information in the Co-op breach but did not access passwords, payment data, or transaction histories. M&S has suspended online orders and is working to restore affected systems. Mandiant has linked the DragonForce ransomware attacks on UK retailers to UNC3944 tactics, highlighting links to RansomHub. UNC3944, also known as Scattered Spider, is a financially motivated threat actor known for its persistent use of social engineering and bold interactions with victims. DragonForce operates under a ransomware-as-a-service (RaaS) model, where affiliates carry out the attacks, keeping most of the ransom, while the group provides the tools and hosts leak sites. The NCSC warns organizations to remain vigilant, with DragonForce hinting at more attacks in the near future. Recommended read:

Following a series of cyberattacks targeting major UK retailers including Marks & Spencer, Co-op, and Harrods, the National Cyber Security Centre (NCSC) has issued an urgent alert, urging organizations to bolster their defenses. The attacks, which involved ransomware and data theft, have caused significant operational disruptions and data breaches, highlighting the increasing risk faced by the retail sector. The NCSC anticipates that similar attacks are likely to escalate and emphasizes that preparation is key to ensuring business continuity and minimizing financial losses.
The NCSC advises businesses to take immediate and proactive measures to mitigate risks. A key recommendation is to isolate and contain threats quickly by severing internet connectivity immediately to prevent malware from spreading further across networks. It's equally important to ensure that backup servers remain isolated and unaffected by the attack, so they can be used for disaster recovery. The security agency is also calling on firms to review their password reset policies, and in particular how IT help desks authenticate workers when they make a reset request, especially in the case of senior employees with escalated privileges. To enhance cyber resilience, the NCSC stresses the importance of implementing multi-factor authentication (MFA) across the board. The agency also warns organizations to be constantly on the lookout for ‘risky logins’ within Microsoft Entra ID Protection, where sign-in attempts are flagged as potentially compromised due to suspicious activity or unusual behaviour. The Information Commissioner's Office (ICO) has similar advice warning organizations to make sure that accounts are protected by a strong password, and that passwords aren't being reused across multiple accounts. While attacks against UK retailers have rocked the industry in recent weeks, the NCSC's guidance aims to help businesses avoid falling victim to similar incidents. Recommended read:
