WannaCry: Kaspersky Records Over 45,000 Attacks in One Day

Barely a week ago, the world, saw the beginning of the Trojan encryptor WannaCry outbreak. It appears to be pandemic — a global epidemic.

“We counted more than 45,000 cases of the attack in just one day, but the true number is much higher,” Kaspersky writes in a blog post.

Recall several large organizations reported an infection simultaneously. Among them were several British hospitals that had to suspend their operations. According to data released by third parties, Kaspersky said that WannaCry has infected more than 200,000 computers. The sheer number of infections is a big part of the reason it has drawn so much attention.

The largest number of attacks occurred in Russia, but Ukraine, India, and Taiwan have suffered much damage from WannaCry as well. In just the first day of the attack, we found WannaCry in 74 countries.

The creators of WannaCry have taken advantage of the Windows exploit known as EternalBlue, which relies on a vulnerability that Microsoft patched in security update MS17-010, dated March 14 of this year. By using the exploit, the malefactors could gain remote access to computers and install the encryptor.

Generally, WannaCry comes in two parts. First, it’s an exploit whose purposes are infection and propagation. The second part is an encryptor that is downloaded to a computer after it has been infected.

“The first part is the main difference between WannaCry and the majority of encryptors. To infect a computer with a common encryptor, a user has to make a mistake, for example by clicking a suspicious link, allowing Word to run a malicious macro, or downloading a suspicious attachment from an e-mail message. A system can be infected with WannaCry without the user doing anything.

“If you have the update installed, then this vulnerability no longer exists for you, and attempts to hack the computer remotely through the vulnerability will fail. However, researchers from Kaspersky Lab’s GReAT (Global Research & Analysis Team) would like to emphasize that patching the vulnerability will not deter the encryptor entirely. Therefore, if you launch it somehow (see the above on making a mistake), then that patch will do you no good.

“After hacking a computer successfully, WannaCry attempts to spread itself over the local network onto other computers, in the manner of a computer worm. The encryptor scans other computers for the same vulnerability that can be exploited with the help of EternalBlue, and when WannaCry finds a vulnerable machine, it attacks the machine and encrypts files on it.

“Therefore, by infecting one computer, WannaCry can infect an entire local area network and encrypt all of the computers on the network. That’s why large companies suffered the most from the WannaCry attack — the more computers on the network, the greater the damage.

WannaCry
“As an encryptor, WannaCry (sometimes called WCrypt or, for no discernable reason, WannaCry Decryptor) behaves like any other encryptor; it encrypts files on a computer and demands ransom to decrypt them. It most closely resembles a variation of the infamous CryptXXX Trojan.

“WannaCry encrypts files of various types (the full list is here) including office documents, pictures, videos, archives, and other file formats that potentially contain critical user data. The extensions of the encrypted files are renamed .WCRY, and the files become completely inaccessible.

“After this, the Trojan changes the desktop wallpaper to a picture that contains information about the infection and actions that the user supposedly has to perform to recover the files. WannaCry spreads notifications as text files with the same information across folders on the computer to ensure that the user receives the message.

“As usual, the actions entail transferring a certain amount of money, in bitcoins, to the wallet of the perpetrators. After that, they say, they will decrypt all of the files. Initially, cybercriminals demanded $300 but then raised the stakes to $600”, the blog post reads.

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

Published

Kindly share this post

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.

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.
