Experts Identify New Ransomware Using BitLocker to Encrypt Corporate Data

Kaspersky has identified ransomware attacks using Microsoft’s BitLocker to attempt encryption of corporate files.

The threat actors remove the recovery options to prevent the files from being restored and use a malicious script with a new feature: it can detect specific Windows versions and enable the BitLocker according to the Windows version.
The incidents with this ransomware, dubbed “ShrinkLocker”, and its variants were observed in Mexico, Indonesia, and Jordan. The perpetrators targeted companies in steel and vaccine manufacturing, and a government entity.
The threat actors are using VBScript – a programming language used to automate tasks on Windows computers – to create a malicious script with previously unreported features to maximise the damage of the attack, Kaspersky Global Emergency Response team reports.
The novelty is that the script checks the current version of Windows installed on the system and enables the BitLocker features accordingly. In this way, the script is believed to be able to infect new and legacy systems back to Windows Server 2008.
In case the OS version is suitable for the attack, the script alters the boot settings and attempts to encrypt the whole drives using BitLocker.
It establishes a new boot partition, essentially setting up a separate section on the computer’s drive containing the files for booting the operating system.
This action is aimed at locking the victim out at a later stage. The attackers also deleted the protectors used to secure BitLocker’s encryption key so that the victim can’t recover them.
The malicious script then sends information about the system and the encryption key generated on the compromised computer to the server controlled by the threat actor. Afterward, it covers its tracks by deleting logs and various files that serve as a hint and help to investigate an attack.
As a final step, malware forces the shutdown of the system – a capability facilitated by the creation and reinstallation of files in a separate boot partition. The victim sees the BitLocker screen with the message: “There are no more BitLocker recovery options on your PC”.
Kaspersky dubbed the script “ShrinkLocker” as this name highlights the critical procedure of partition resizing, which was essential for the attacker to ensure the system booted correctly with the encrypted files.
“What is particularly concerning about this case is that BitLocker, originally designed to mitigate the risks of data theft or exposure, has been repurposed by adversaries for malicious ends.
“It’s a cruel irony that a security measure has been weaponised in this way. For companies using BitLocker, it’s crucial to ensure strong passwords and secure storage of recovery keys. Regular backups, kept offline and tested, are also essential safeguards,” explains Cristian Souza, Incident Response Specialist at Kaspersky Global Emergency Response Team.

Nigeria Targeted with 4,622 Cyber-attacks Per Week in December 2025

In December 2025, organisations globally faced sustained cyber pressure, as the average number of cyber-attacks per organisation per week reached 2 027, a 1% increase from the previous month and a 9% increase from December 2024.

This is according to December 2025 Global Cyber Attack Statistics by Check Point Research, the threat intelligence arm of Check Point Software Technologies.
According to the statistics, Latin America was the hardest hit, with companies experiencing an average of 3 065 cyber-attacks per week, a 26% year-over-year increase.
In contrast, Africa saw a decline in attacks, with Nigeria (4 622 attacks per week) and Angola (4 002 attacks per week) being the most targeted countries on the continent.
The report’s findings highlight the evolving cyber threat landscape, with ransomware and GenAI-driven data risks posing significant challenges to companies worldwide.
Ransomware attacks jumped 60% year over year, with 945 publicly reported incidents in December. Qilin was the most active ransomware operator, responsible for 18% of publicly disclosed attacks.
“Ransomware continues to scale through industrialised operations, while unmanaged GenAI usage is creating widespread data exposure at enterprise level,” said Omer Dembinsky, data research manager at Check Point Research.
The report noted the education sector was the most targeted industry globally, with 4 349 cyber attacks per week; followed by government (2 666 attacks per week); and associations and non-profits (2 509 attacks per week).
The widespread adoption of GenAI tools has introduced new cyber security risks, with one in 27 GenAI prompts posing a high risk of sensitive data leakage.
Experts warn that companies must prioritise prevention-first security, real-time AI threat intelligence and strong governance over AI tools to mitigate these risks.
Hendrik de Bruin, head of security consulting at Check Point Software, added: “Strengthening ransomware resilience, deploying AI-powered prevention and enforcing clear GenAI governance will be critical to reducing cyber risk in the year ahead.”

Half of Global Companies Build SOCs to Enhance Cybersecurity, with a Focus on Human Expertise

Among the primary reasons for establishing a Security Operations Center (SOC) are strengthening cybersecurity posture, enabling faster detection and response and gaining a competitive edge.

Interestingly, despite the increasing demand for automated cybersecurity solutions, businesses rely on skilled security professionals to make key decisions, as human expertise remains essential for effective security management.
A Security Operations Center (SOC) is a dedicated organisational unit responsible for continuous monitoring and safeguarding of a company’s IT infrastructure. Its core mission is to proactively detect, analyse and respond to cybersecurity threats.
To identify the main drivers, strategic priorities, and potential challenges in SOC planning and implementation, Kaspersky has conducted a comprehensive global study involving senior IT security specialists, managers and directors from companies with 500 or more employees.
All participants operate without a SOC but have plans to establish one in the near future. The study spans 16 countries across APAC, META, LATAM, Europe, and Russia, providing valuable insights into the emerging trends and best practices in SOC development worldwide.
The findings of the research reveal that 50% of companies intend to establish SOCs to strengthen their cybersecurity posture, and 45% are motivated by the need to address increasingly sophisticated and dangerous threats.
Other drivers include budget optimisation, the necessity for faster detection and response, and the expansion of software, endpoints and user devices – factors that demand more comprehensive and layered security measures.
These are cited by 41% of organisations. Additionally, 40% seek better protection of confidential information, 39% aim to meet regulatory requirements and one-third (33%) expect SOC capabilities to provide a competitive edge. Larger enterprises tend to cite each of these reasons more often, reflecting the broader operational and regulatory pressures they experience.
Continuous monitoring becomes the leading SOC requirement
Among the key functions organisations plan to delegate, 24/7 security monitoring leads at 54%. This around-the-clock vigilance enables early detection of anomalies, prevents escalation and sustains cyber resilience in real-time. This demand highlights a strategic requirement for proactive risk management, as organisations aim to defend against persistent threats that can strike at any moment.
Companies intending to fully outsource SOC operations show a stronger interest in applying “lessons learned” methodologies, whereas those developing internal SOCs focus more on access management to maintain tighter control.
Human expertise drives SOC technology choices
While SOCs use advanced technology, the choices made by organisations show that human analysts are very important. Among the solutions that organisations plan to include in SOC are – Threat Intelligence Platforms (48%), Endpoint Detection and Response (42%) and Security Information and Event Management systems (40%) – sophisticated solutions that automate data collection and reduce operational load, however, they depend heavily on skilled security professionals who provide critical context, interpret complex findings and make final decisions when guiding appropriate responses.
Other solutions chosen include Extended Detection and Response (38%), Network Detection and Response (37%) and Managed Detection and Response (33%). Large enterprises tend to adopt more technologies (5.5 per SOC on average), while smaller ones integrate fewer (3.8).
“To successfully build a SOC, companies must prioritise not only the right mix of technology but also the careful planning of processes, clear goal-setting and effective resource distribution.
“Well-defined workflows and continuous improvement are essential to ensure that human analysts can focus on critical tasks, making the SOC a proactive and adaptable component of their cybersecurity strategy,” comments Roman Nazarov, Head of SOC Consulting at Kaspersky.

Nigerian Terra Industries Secures $11.8m for Expansion

Terra Industries, a Nigerian defence technology startup, has raised $11.75 million to expand its development of defensive systems that protect critical facilities across Africa.

The fundraising round was led by Silicon Valley venture firm 8VC, which was founded by Palantir co-founder Joe Lonsdale.
Other investors in the round include Valour Equity Partners, Lux Capital, SV Angel, and Nova Global, as well as African-focused funds Tofino Capital, Kaleo Ventures, and DFS Lab.
Terra Industries, founded in Abuja by Nathan Nwachuku and Maxwell Maduka, provides multi-domain security solutions for both air and land. Its solutions are intended to detect and respond to threats including terrorism, sabotage, and armed attacks on infrastructure.
The company’s product portfolio includes surveillance drones, ground-based robotic systems, and fixed monitoring towers deployed around sensitive locations.
Co-founder and CEO Nathan Nwachuku said the company has now fully embraced its identity as a defence-focused startup, citing the growing urgency of security challenges across Africa.
He said safeguarding critical infrastructure from terrorist threats has become unavoidable.
Nwachuku argues that protecting Africa’s infrastructure requires a different approach, one that combines local manufacturing, end-to-end system control, and software capable of independently identifying and responding to threats over large areas.
The company aims to position itself as a defence prime, similar to the role played by firms such as Anduril Industries and Palantir in the United States.
Nwachuku also disclosed that the company had earlier raised $800,000 in pre-seed funding.
With the new funding, Terra plans to increase manufacturing capacity within Africa, establish additional defence production facilities, and expand its artificial intelligence and software teams.
While software offices are planned for San Francisco and London, the company said manufacturing operations will remain on the continent.
