Kaspersky detected and blocked 45,562 cyberattacks on Internet of Things (IoT) devices in Kenya and 30,089 cyberattacks on IoT devices in Nigeria.

In South Africa this figure is 221,695. All these attacks were blocked on Kaspersky honeypots – decoy devices used to attract the attention of cybercriminals and analyse their activities.

IoT devices include wearables, smart home appliances, smart city systems, self-driving cars, automated retail checkouts, and other smart devices for home and business use.

These devices can collect and transfer data over a wireless network without human input. Cybercriminals use networks of infected smart devices to conduct DDoS attacks or as a proxy for other types of malicious actions.

The number of attacks on IoT devices has been increasing exponentially over the last years. This is related both to the activity of criminal actors and to the increasing number of IoT devices that are in use.

According to open research, in 2020 there were 42,4 million IoT devices operating in Sub-Saharan Africa. By 2030, the number is expected to triple and reach 264 million¹. Capitalising on weak security of IoT devices, cybercriminals are intensifying their attacks.

A brute force attack uses trial-and-error to guess login and password info or encryption keys, with hackers working through all possible combinations to guess correctly.

In the African region throughout 2022 there were over 93,000 attempts to brute force logins and passwords to IoT devices using only the most popular combinations (examples are provided in the table below); the total number of brute force attempts is even higher.

“As the number of IoT devices grows and attacks intensify, cybercriminals use both advanced and simple tactics to infiltrate smart devices. One of these tactics is using simple password and login combinations – our research showed that on hundreds of thousands of IoT devices the most common login-password combinations are admin-admin, guest-guest, or other variants that come as default on different kinds of equipment,” commented Vladimir Dashchenko, security expert at Kaspersky ICS CERT². “It is easy to change the default password, so we urge everyone to take this simple step towards securing your smart devices.

Speaking of more thorough protection, IoT vendors should consider implementing the next generation cybersecurity approach in their products – where devices would feature innate, built-in protection that would make them Cyber Immune.

Such technology is already available on the market, including offers from Kaspersky. For instance, Kaspersky IoT Secure Gateway system is designed to serve as a secure gateway for the Internet of Things on an enterprise network.”

Given the diversity of IoT devices and their related cybersecurity risks, the need for their protection is clear, especially when it comes to smart cities or critical infrastructure. Traditional measures are not sufficient for IoT protection, making it crucial that specialised security solutions are implemented.

To keep your devices safe, Kaspersky recommends users:

  • Install updates for the firmware you use as soon as possible. Once a vulnerability is found, it can be fixed through patches within updates.
  • Periodic rebooting will help get rid of malware already installed (although in most cases the risk of reinfection will remain).
  • Change the factory passwords at initial setup, use complex passwords at least 8 characters long, including upper and lower-case letters, numerals, and special characters.
  • Use a strict access policy, network segmentation and a zero-trust model. This will help minimise the spread of an attack and protect the most sensitive parts of the infrastructure.

Kaspersky Discovers New Phishing Campaign Exploiting Google Tasks Notifications to Steal Corporate Credentials

Published

Kindly share this post

Kaspersky has uncovered a new phishing scheme that abuses legitimate Google Tasks notifications to trick corporate users into revealing corporate login credentials.

By leveraging Google’s trusted @google.com email domain and notification system, attackers bypass traditional email security filters and exploit users’ trust in familiar services.

In this campaign, victims receive an authentic-looking notification from Google Tasks with the subject line “You have a new task.” The message creates the illusion that the recipient’s company has adopted Google’s task management tool, pressuring them to act quickly. The notification often includes elements of urgency, such as a high-priority flag and a tight deadline, to prompt the victim’s immediate response.

Upon clicking the embedded link, users are directed to a fraudulent form disguised as an “employee verification” page, where they are asked to enter their corporate credentials under the pretense of confirming their status. These stolen credentials can then be used for unauthorised access to company systems, data theft, or further attacks.

“Google’s vast ecosystem of services gets exploited by scammers. The scheme with Google Tasks is part of a broader trend observed before and continuing into 2026, where cybercriminals misuse legitimate platforms to distribute scams and phishing.

Notifications originating from legitimate domains naturally evade many spam and phishing filters, while the social engineering aspect – making it seem like an internal company process – lowers the victim’s guard,” comments Roman Dedenok, Anti-Spam Expert at Kaspersky.

esentry 2025 Report Shows Healthcare, Financial Services and Telecoms as Staging Grounds for Increased Cyberattacks in Africa

Published

Kindly share this post

Cyber adversaries targeting African organisations are increasingly shifting away from opportunistic attacks toward deliberate, sector-specific campaigns aimed at the continent’s most critical digital infrastructures, according to the esentry 2025 Annual Report released by esentry, Lagos-based Africa’s leading indigenous Managed Security Service Provider (MSSP).

The report identifies healthcare, financial services, and telecommunications as the primary staging grounds for high-velocity cyberattacks, reflecting a growing focus on sectors that underpin economic stability, public welfare, and digital connectivity across Africa.

The findings are drawn from one of the largest cybersecurity datasets analysed in the region. Over the course of 2025, esentry processed more than 31 billion security events, generating 3.5 million alerts and successfully blocking over 15,000 malicious attempts. This monitoring scale shows that, while traditional financial institutions remain a core target, the threat landscape has expanded to include digital lending platforms, healthcare systems that store sensitive personal data, and telecom operators responsible for national and regional connectivity.

Within the healthcare sector, the report highlights ransomware as the most acute risk, with attackers frequently exploiting exposed Remote Desktop Protocol (RDP) services to compromise patient data and disrupt essential medical operations. In financial services, organisations are facing a surge in credential abuse, insider-related threats, and info-stealer malware designed to enable fraud and unauthorised access. Telecommunications providers are increasingly targeted by highly tailored phishing campaigns and attacks on exposed web services, which aim to harvest credentials and compromise customer data.

Commenting on the findings, Gbolabo Awelewa, Chief Business Officer at esentry, said the nature of cyber threats across Africa has evolved significantly. “The threats we are seeing today are deliberate, informed, and carefully tailored to local enterprises. Attackers are exploiting trusted access and moving quietly within networks, which makes early detection critical. Our coordinated cybersecurity model, spanning Defence, Intelligence, Offence, and Security Engineering, allows us to combine scale, speed, and deep contextual insight to detect and neutralise threats before they escalate,” Awelewa said.

A defining trend identified in the report is the shift from overt system exploitation to the abuse of legitimate access. By leveraging compromised credentials and ‘living-off-the-land’ techniques, attackers can blend into routine enterprise operations and significantly delay detection. This approach has compressed the attack lifecycle, enabling adversaries to move from initial access to full operational impact in fewer than 15 days.

To counter this acceleration, the report emphasises the importance of early detection and automated response. esentry says it currently contains low-complexity incidents in under 90 seconds, using a combination of structured threat hunting and centralised telemetry to anticipate and absorb attacker pressure rather than reacting after damage has occurred.

As African organisations continue to digitise, the esentry 2025 Annual Report positions itself as a critical reference point for understanding the continent’s evolving cyber threat environment. The report concludes that protecting Africa’s digital trust will require a shift away from fragmented security tools toward disciplined, coordinated defence frameworks, what esentry describes as a unified Phalanx formation.
