Preventing, Mitigating Ransomware with Cyber Situational Awareness
If you’re familiar with mafia movies then you’re familiar with extortion – the practice of obtaining something, especially money, through force or threats.
Extortion has been around for centuries – well before “The Godfather” or “Goodfellas.” Even cyber extortion, which extends this criminal activity into the digital world, isn’t new.
What is new, however, is the wide variety of methods that are used by the bad guys to get their money.
Three main tactics are behind cyber extortion: the threat of distributed denial of service (DDoS), the threat of data compromise and ransomware.
DDoS attacks are one of the most popular means to facilitate extortion. These types of attacks typically target business-critical websites in order to increase the likelihood of payment, usually via Bitcoin (BTC), and can have crippling effects on organizations.
In certain cases, such as when targeting hosting providers, the threat actor may add more pressure to pay by using the negative publicity associated with service downtime as a threat.
A second method of extortion involves the potential release of compromised data. This method is dependent on the fact that the target’s data has already been compromised.
The threat of its release to the public domain is used as blackmail in order to extort money from the affected entity.
A third type of extortion, and the one most often in the news as of late, is ransomware – malicious software (malware) that restricts access to the computer system it has infected.
The malware demands that a ransom be paid before restoring access to affected resources.
Ransomware can prevent access to many features of a victim’s machine, including files, applications and the operating system itself.
Because ransomware is an ever-evolving threat that can be more challenging to address than other cyber extortion tactics, let’s take a closer look at how it works and how to prevent and mitigate it.
At a high-level, the ransomware process is fairly standard. Files are encrypted and the attackers, who hold the decryption key, will only allow the target to decrypt the files after the required BTC ransom is paid. Specific details of the attack, however, will depend on the variant.
Until recently ransomware has been delivered most commonly via drive-by-downloads from exploit kits, or through spam emails that either contain malicious attachments or encourage recipients to visit websites hosting malicious content.
But we see that starting to change with threat actors using more targeted methods to achieve their objective, such as spear-phishing emails purporting to be from a job applicant or including the name, job title and job-relevant information of the recipient.
The disclosure that some organizations are paying the fee to unencrypt data likely provides further motivation for these types of attacks. In fact, when the actor estimates there’s a high likelihood of payment of the ransom fee they invest in more reconnaissance which can further increase the likelihood of infection.
As ransomware becomes big business, research on the dark web reveals a number of services being advertised to make it easy for beginners with low technical understanding to execute ransomware attacks with success.
Everything they need is available on a USB stick for $1,200 or they can take advantage of a hosted service in return for 5 percent commission on the ransom payments received.
So how can you combat cyber extortion? Cyber situational awareness can give you greater insights into the tools and processes used by actors that employ DDoS-based extortion and compromised data release extortion.
Advanced knowledge of the typical demands of a threat actor and their capabilities can help you make difficult decisions if presented with such a scenario and help you prevent future attacks.
Mitigating ransomware threats is more complex. It requires a combination of technical and process controls and company-wide engagement – from employees, to executives, to IT security teams. Cyber situational awareness can help you understand the infection vectors of the malware and apply the appropriate security controls to mitigate the risk of infection.
This includes insights you can use to raise staff awareness of how ransomware attacks occur and help you devise technical and procedural controls to prevent infection and to develop ransomware response procedures in the case of infection.
Of course ensuring that backups are maintained and are separate from the network can increase resilience to such attacks. In addition, several decryption tools have been released but, in the cat and mouse game between ransomware and such tools, their effectiveness tends to be short-lived; ransomware developers are continuously developing encryption methods to evade them.
As defenders, staying up-to-date with the latest trends and innovation can be hard, but it is essential in order to effectively prevent and mitigate the effects of extortion on your business.
With cyber situational awareness you can learn about the actors involved in extortion and their tactics, tools and motivations. With this knowledge you can more effectively align your defenses and make better decisions in the face of an attack.

National Information Technology Development Agency (NITDA), in partnership with the Advocacy for Policy and Innovation (API), has convened a one-day workshop in Abuja to advance dialogue on the draft Online Harm Protection (OHP) Bill to confront harmful online content.
The bill, a rights-based, locally rooted, and multi-stakeholder initiative, is aimed at addressing the challenges of the digital age.
The event, which held yesterday, brought together government officials, civil society, academics, digital platforms, and legal experts to shape a policy framework designed to combat online ills such as cyberbullying, disinformation, hate speech, digital exploitation, and gender-based violence, while safeguarding democratic freedoms and digital inclusion.
In his keynote remarks, Kashifu Inuwa, director general, NITDA urged a paradigm shift in the way society engages with digital technologies.
“For almost two decades, we have viewed digital technology through a consumer lens. But these technologies are not just products and services. They are transforming how we live, work, and interact. They shape our politics, our society, and our democracy,” he said.
Warning against unaccountable digital power in the hands of private corporations, the DG likened the digital journey to the tale of Alice in Wonderland, where initial fascination with innovation has given way to deeper concerns about privacy, autonomy, and manipulation by big tech platforms.
“We thought we were using Google, but now we realise Google is using us. Social media, once a tool of expression, has become a tool of surveillance and influence,” Inuwa noted.
He, therefore, emphasised the urgency of developing a democratic and accountable framework. He explained that following the 2021 Twitter ban, NITDA facilitated dialogue between the government and platform operators, leading to a Code of Practice that stressed Nigeria’s sovereignty and legal standards.
According to him, the same process birthed the multi-stakeholder steering committee and the OHP White Paper in December 2024, laying the foundation for the current legislative push.
Earlier in her opening remarks, Victoria Manya, co-founder, API, observed the moral and civic necessity of the bill.
Her words: “The internet did not break society, it merely revealed its unfiltered version. Every day, Nigerians are exposed to harassment, disinformation, exploitation, and even algorithmic violence. The OHP Bill is not a war on the Internet. It is a peace offering to its users, a social contract for a digital future that is safe, inclusive, and democratic.
“We cannot answer the question of algorithmic power with unchecked state control. We must answer it with shared, rights-based governance. This bill must not be written for the people, but with them.”
These days, people rely heavily on their mobile phones for talking, texting, banking, social media, and storing important personal information. Because of this, scammers and spammers often target phone users.
Mobile fraud, like fake SMS messages and scams, is becoming more common and putting millions at risk of losing money or having their private details stolen.
Airtel’s new AI-powered Spam Alert Service offers a smart and timely way to fight back, marking a major step forward in protecting mobile users in Africa.
A brief look at mobile fraud and spam
Mobile fraud and spam are problems around the world, but they hit harder in places where mobile phone use is growing fast, and safety measures haven’t caught up.
A 2024 report from GSMA Mobile Economy shows that more than 20% of mobile users globally have experienced some kind of mobile fraud, with spam texts being one of the most common.
In Nigeria, the Nigerian Communications Commission (NCC) has noted a sharp rise in scam messages and fake calls, leading to yearly losses in the hundreds of millions of dollars.
These spam texts often include fake links, harmful ads, or tricks to steal personal details. Many people get caught without knowing, which can lead to stolen bank money, identity theft, or damaged devices.
Older spam blockers only work on certain phones or apps, leaving many people, especially those using basic phones, without protection.
Why Airtel’s AI Spam Alert Service stands out
Airtel, a top telecom company in Africa, has launched a new and free service called the AI Spam Alert Service. It’s the first of its kind in Africa and aims to protect mobile users from spam text messages as they come in.
What makes this service different is that it doesn’t read or check the actual message content. Instead, it uses advanced artificial intelligence to quickly study the sender’s behaviour using over 250 signs or patterns, all within a fraction of a second.
Some of those parameters, according to Airtel, includes:
- How frequently the sender changes SIM cards.
- The volume and frequency of messages sent by the message initiator to different recipients.
- The geographical spread of the recipient numbers, whether messages are targeted locally or dispersed nationwide.
- Whether the sender receives replies or only sends messages.
- A cross-reference of numbers previously reported for spam activity.
The AI completes this analysis in just 2 milliseconds, faster than the blink of an eye, allowing real-time alerts to subscribers as suspected spam messages arrive.
How Airtel’s Spam Alert Service improves mobile safety and trust
Airtel’s new AI-powered spam alert system is set to make a big difference in mobile security across Nigeria and the rest of Africa. Instead of depending on users to block spam themselves, the service works directly through the network to stop suspicious messages before they reach people’s phones.
This kind of technology helps users feel safer and more confident using mobile networks—especially as more people rely on their phones for banking and other money-related services.
A 2025 report by McKinsey Digital shows that many Africans worry about mobile security when using digital financial tools. By reducing the risk of spam and fraud, Airtel is not only protecting its users but also helping to build a safer digital space where more people can take part in the growing mobile economy.
According to Airtel, within two months of its launch, the spam alert service system has identified 9,667,008 messages as potential spam.
Why this is a game changer
By building a service that is first-of-its-kind in Africa, Airtel is leading the way in offering spam alerts, powered by AI directly on its network, for over 150 million subscribers across the continent.
In addition, the service is quick, spotting suspicious sender activity in just milliseconds without reading users’ messages.
Finally, the service is free and requires no app downloads or extra setup. Airtel says the turns on automatically, making it easy for everyone to stay protected, even those using basic phones.
By sending signals to users before problems happen, Airtel boosts trust and encourages more people to safely use mobile money and other digital services.
Scammers are always finding new ways to trick consumers through the ubiquitous mobile phones, so increased demand for security improvements is, understandably, shifting to telecom companies.
Airtel’s AI Spam Alert Service is a strong and timely move toward better, smarter protection for users. As more people start using the service, it should help cut down fraud, keep personal information safe, and make mobile use more enjoyable.
As African economies continue to grow more digital, users of telecom services will need more secure and reliable ways to communicate, and Airtel is leading the way towards that safe future.
A widespread cyberattack targeting Microsoft’s (MSFT.O) server software used by thousands of government agencies and businesses for internal document sharing was likely orchestrated by a single actor, a cybersecurity researcher said on Monday.
Microsoft issued an alert on Saturday warning of “active attacks” on on-premise SharePoint servers.
The company clarified that SharePoint Online, part of the Microsoft 365 cloud suite, was not affected by the exploit, which is considered a “zero-day” vulnerability due to its previously undiscovered nature.
“Based on the consistency of the tradecraft seen across observed attacks, the campaign launched on Friday appears to be a single actor. However, it’s possible that this will quickly change,” Rafe Pilling, director of Threat Intelligence at Sophos, a British cybersecurity firm.
That tradecraft included the sending of the same digital payload to multiple targets, Pilling added.
Microsoft said it had “provided security updates and encourages customers to install them,” a company spokesperson said in an emailed statement.
It was not clear who was behind the ongoing hack. The FBI said on Sunday it was aware of the attacks and was working closely with its federal and private-sector partners, but offered no other details.
Britain’s National Cyber Security Centre did not immediately respond to a request for comment.
The Washington Post said unidentified actors in the past few days had exploited a flaw to launch an attack that targeted U.S. and international agencies and businesses.
According to data from Shodan, a search engine that helps to identify internet-linked equipment, over 8,000 servers online could theoretically have already been compromised by hackers.
Those servers include major industrial firms, banks, auditors, healthcare companies, and several U.S. state-level and international government entities.
“The SharePoint incident appears to have created a broad level of compromise across a range of servers globally,” said Daniel Card of British cybersecurity consultancy, PwnDefend.
“Taking an assumed breach approach is wise, and it’s also important to understand that just applying the patch isn’t all that is required here.”
