Pearson, the global education and publishing giant, has confirmed it suffered a cyberattack resulting in the theft of corporate data and customer information. The breach was discovered by BleepingComputer, who reported that the attackers gained unauthorized access to Pearson's systems. Pearson, a UK-based company, is a major player in academic publishing, digital learning tools, and standardized assessments, serving schools, universities, and individuals across over 70 countries.
Pearson stated that after discovering the unauthorized access, they acted to stop the breach, investigate the incident, and ascertain what data was affected with forensics experts. They also supported law enforcements investigation. Furthermore, Pearson said they've taken steps to deploy additional security measures onto their systems, including enhanced security monitoring and authentication. BleepingComputer was tipped off that someone used an exposed GitLab Personal Access token to compromise Pearson’s development environment in January 2025. The token was found in a public .git/config file, with the attackers using this access to find even more login credentials, hardcoded in the source code, which they then used to infiltrate the company’s network and steal corporate and customer information. The company downplayed the significance of the breach, suggesting the stolen data was largely outdated, referring to it as "legacy data." Pearson has not disclosed the number of individuals affected, nor the specific types of information exposed. There was no employee information among the stolen files, it was confirmed.

The ransomware landscape is experiencing significant shifts in April 2025, with groups like Qilin taking center stage. Despite a general decline in ransomware attacks from 564 in March to 450 in April, the lowest level since November 2024, Qilin has surged to the top of the ransomware rankings. This rise is attributed to the realignment of cybercriminal groups within the chaotic Ransomware-as-a-Service (RaaS) ecosystem. Qilin is reportedly leveraging sophisticated tools and techniques, contributing to their increased success in recent months.
Qilin's success is partly due to the adoption of advanced tactics, techniques, and procedures (TTPs). Threat actors associated with Qilin have been observed utilizing malware such as SmokeLoader, along with a previously undocumented .NET compiled loader called NETXLOADER, in campaigns dating back to November 2024. NETXLOADER is a highly obfuscated loader designed to deploy additional malicious payloads and bypass traditional detection mechanisms, making it difficult to analyze. This loader plays a critical role in Qilin's stealthy malware delivery method. The surge in activity is reflected in the doubling of disclosures on Qilin's data leak site since February 2025, making it the top ransomware group in April. The emergence of new actors like DragonForce is reshaping the threat landscape. The group is built for the gig economy. Its features include a 20% revenue share, white-label ransomware kits, pre-built infrastructure. DragonForce quickly moved to absorb affiliates following the April 2025 disappearance of RansomHub, pitching itself as an agile alternative to collapsed legacy operators. A historic surge in ransomware activity is occurring. A total of 2,289 publicly named ransomware victims were reported in just Q1 a 126% year-over-year increase, setting an all-time high. 74 distinct ransomware groups are now operating concurrently, highlighting an explosion of new actors and affiliate-driven threats.

The LockBit ransomware group, a major player in the Ransomware-as-a-Service (RaaS) sector, has suffered a significant data breach. On May 7, 2025, the group's dark web affiliate panels were defaced, revealing a link to a MySQL database dump containing sensitive operational information. This exposed data includes Bitcoin addresses, private communications with victim organizations, user credentials, and other details related to LockBit's illicit activities. The defacement message, "Don't do crime CRIME IS BAD xoxo from Prague," accompanied the data leak, suggesting a possible motive of disrupting or discrediting the ransomware operation.
The exposed data from LockBit's affiliate panel is extensive, including nearly 60,000 unique Bitcoin wallet addresses and over 4,400 victim negotiation messages spanning from December 2024 through April 2025. Security researchers have confirmed the authenticity of the leaked data, highlighting the severity of the breach. The LockBit operator, known as "LockBitSupp," acknowledged the breach but claimed that no private keys were compromised. Despite previous setbacks, such as the "Operation Cronos" law enforcement action in February 2024, LockBit had managed to rebuild its operations, making this recent breach a significant blow to their infrastructure. Analysis of the leaked information has uncovered a list of 20 critical Common Vulnerabilities and Exposures (CVEs) frequently exploited by LockBit in their attacks. These vulnerabilities span multiple vendors and technologies, including Citrix, PaperCut, Microsoft, VMware, Apache, F5 Networks, SonicWall, Fortinet, Ivanti, Fortra, and Potix. Additionally, the leaked negotiations revealed LockBit’s preference for Monero (XMR) cryptocurrency, offering discounts to victims who paid ransoms using this privacy-focused digital currency. Ransom demands typically ranged from $4,000 to $150,000, depending on the scale of the attack. Recommended read:

In December 2024, PowerSchool, a major provider of K-12 software serving 60 million students across North America, experienced a significant data breach. Hackers gained access to sensitive student and teacher data, including personally identifiable information such as Social Security numbers and health data, through a single stolen credential. The company, believing it was the best course of action, paid an undisclosed ransom to the threat actor to prevent the data from being made public, however this has proven to be unsuccessful.
Months later, it has been revealed that the threat actors are now directly targeting individual school districts with extortion demands, using the stolen data from the initial breach. The Toronto District School Board (TDSB), along with other schools in North America, has confirmed receiving ransom demands from the attackers. The exposed information includes names, contact details, birth dates, Social Security numbers, and even some medical alert data. PowerSchool has confirmed that these extortion attempts are related to the original breach and is working with law enforcement. Cybersecurity experts have warned against paying ransoms, as there is no guarantee that hackers will delete the stolen data. This case exemplifies the risk of paying extortion demands, as the threat actors have resurfaced to revictimize affected individuals and institutions with additional demands. PowerSchool is offering two years of free identity protection to affected individuals, however there will be pressure for them to improve its security and reassure stakeholders that it can prevent similar incidents in the future.

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:

A hacker has successfully breached TeleMessage, an Israeli company that provides modified versions of secure messaging apps such as Signal, WhatsApp and Telegram to the U.S. government. The breach resulted in the exfiltration of sensitive data, including archived messages from these modified apps. TeleMessage has suspended all services and is currently investigating the incident. The breach highlights the vulnerabilities associated with modifying secure messaging applications, especially concerning the preservation of end-to-end encryption.
The compromised data includes the contents of direct messages and group chats, as well as contact information for government officials. 404 Media reported that the hack exposed data related to U.S. Customs and Border Protection (CBP), the cryptocurrency exchange Coinbase, and several other financial institutions. The hacker claimed the entire process of accessing TeleMessage’s systems took only 15-20 minutes, underscoring the ease with which the security was circumvented. Despite the breach, there are reports that messages from top US government officials and cabinet members were not compromised. TeleMessage, which was recently in the spotlight after former U.S. National Security Advisor Mike Waltz was seen using their modified version of Signal, offers archiving services for messages. However, the hack revealed that the archived chat logs were not end-to-end encrypted between the modified app and the ultimate archive destination controlled by the TeleMessage customer. Smarsh, the parent company of TeleMessage, has engaged an external cybersecurity firm to support the investigation and has temporarily suspended all TeleMessage services as a precaution. A Coinbase spokesperson stated that the company is closely monitoring the situation, but has not found any evidence of sensitive customer information being accessed or accounts being at risk.

Ryan Kramer, a 25-year-old from California, has pleaded guilty to two criminal charges related to a significant data breach at Disney. Kramer, operating under the alias "NullBulge," admitted to illegally accessing Disney's internal Slack channels and stealing over 1.1 terabytes of confidential data. The stolen data included internal communications, sensitive information, images, source code, and credentials. The breach led Disney to switch from Slack to Microsoft Teams following the incident, which impacted over 10,000 Slack channels.
He distributed a malicious program, disguised as an AI-powered image generation tool, on platforms like GitHub. This program contained a backdoor that allowed him to access the computers of those who downloaded and executed it. According to prosecutors, a Disney employee fell victim to this poisoned project between April and May of 2024, inadvertently granting Kramer access to their network and online credentials. This initial breach then allowed Kramer to move laterally within Disney's systems, compromising various platforms and confidential data storage areas. Armed with the stolen data, Kramer, falsely claiming affiliation with the Russian hacking group NullBulge, attempted to extort the victim. When the victim did not respond, Kramer proceeded to release their personal information, including bank, medical, and other sensitive details, across multiple platforms. While Kramer awaits sentencing, he faces a maximum of five years in federal prison for each felony count of accessing a computer to obtain information and threatening to damage a protected computer. The FBI is also investigating the extent to which data from at least two other victims who downloaded Kramer's malicious GitHub project may have been compromised. 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:
