Qbot, April 2023’s Most Wanted Malware Launches Substantial Malspam Campaign

Check Point® Software Technologies, a leading provider of cybersecurity solutions globally, has published its Global Threat Index for April 2023.
Last month, researchers uncovered a substantial Qbot malspam campaign distributed through malicious PDF files attached to emails seen in multiple languages. Meanwhile, Internet-of-Things (IoT) malware Mirai made the list for the first time in a year after exploiting a new vulnerability in TP-Link routers, and Healthcare moved up to become the second most exploited industry.
The Qbot campaign seen last month involves a new delivery method in which targets are sent an email with an attachment that contains protected PDF files. Once these are downloaded, the Qbot malware is installed on the device. Researchers found instances of the malspam being sent in multiple different languages, which means organizations can be targeted worldwide.
Last month also saw the return of Mirai, one of the most popular IoT malwares. Researchers discovered it was exploiting a new zero-day vulnerability CVE-2023-1380 to attack TP-Link routers and add them to its botnet, which has been used to facilitate some of the most disruptive distributed DDoS attacks on record. This latest campaign follows an extensive report published by Check Point Research (CPR) on the prevalence of IOT attacks.
There was also a change in impacted industries, with healthcare overtaking government as the second most exploited sector in April. Attacks on healthcare institutions have been well documented and some countries continue to face constant assaults.
For example, cybercriminal group Medusa recently launched attacks on cancer facilities in Australia. The industry remains a lucrative target for hackers as it gives them potential access to confidential patient data and payment information. It could have implications for pharmaceutical companies as it could lead to leaks regarding clinical trials or new medical drugs and devices.
“Cybercriminals are constantly working on new methods to bypass restrictions and these campaigns are further proof of how malware adapts to survive. With Qbot on the offensive again, it acts as another reminder of the importance of having comprehensive cybersecurity in place, and due diligence when it comes to trusting the origins and intent of an email.” said Maya Horowitz, VP Research at Check Point Software.
CPR also revealed that “Web Servers Malicious URL Directory Traversal” was the most exploited vulnerability, impacting 48% of organizations globally, followed by “Apache Log4j Remote Code Execution” with 44% and “HTTP Headers Remote Code Execution” with a global impact of 43%.

NIPOST Partners KLM on Global Mail Delivery

Nigerian Postal Service (NIPOST) has signed an international mail partnership with KLM Royal Dutch Airlines for improved delivery access to over 200 countries without middlemen.
Tolani Odeyemi, postmaster-general and chief executive officer of NIPOST, described the deal as a “major milestone” for the country’s logistics and postal sector.
In a statement on X on Monday, Odeyemi explained that the new agreement marks NIPOST’s first direct international airline partnership for several years.
“For a long time, NIPOST operated without any direct partnerships with international airlines, relying heavily on multiple third-party handlers,” the Postmaster-General stated. This often resulted in delays, higher costs, and uncertainty around the delivery of packages.”
She explained that under the new arrangement, KLM will directly handle all outbound international mail from Nigeria, eliminating the need for intermediaries.
“This translates to faster and more reliable delivery, reduced risk of loss or damage, lower handling charges, and access to over 200 countries through KLM’s global network,” the Postmaster-General stressed.
According to Odeyemi, NIPOST’s breakthrough came after it began settling long-standing debts owed to international carriers, a step she said was key to “rebuilding global trust” in Nigeria’s postal system.
She revealed that talks were also ongoing with Ethiopian Airlines to bolster regional and continental logistics, particularly on African and Eastern routes.
“Our goal is clear and unwavering: to connect Nigeria regionally and globally, efficiently, securely, and affordably,” Odeyemi asserted.
The NIPOST CEO described the development as a significant win for Nigerian businesses and small and medium-scale enterprises that rely on international shipping, stating, “You now benefit from quicker, more affordable international shipping, greater peace of mind with improved reliability, and new potential to reach and grow in global markets.”
Odeyemi commended the teams behind the scenes and pledged continued improvements in service delivery, adding that the deal signals a turning point for the agency.

Why Even the Most Experienced can Fall Victim of AI Phishing Attacks

The evolution of AI is not only affecting various industries, but it has also transformed cybercriminals’ tactics. One alarming trend is the use of AI to enhance phishing scams, refining them, targeting specific individuals, and making these attacks almost impossible to recognise.
Kaspersky reviews how AI is changing phishing techniques and why even the most cyber-aware employees may fall for these scams.
According to a recent Kaspersky study, the number of cyberattacks experienced by organisations in the last 12-months is reported to have increased by nearly half (48%) in the Middle East, Turkiye and Africa (META) region.
The most ubiquitous threat came from phishing attacks, with 51% of those questioned in the META region reporting this type of incident. With AI becoming a more prevalent enabler for cybercriminals, over half of the respondents in META (53%) anticipate significant growth in the number of phishing attacks. In this text, Kaspersky examine how AI is used in phishing and why experience alone is sometimes not enough to avoid becoming a victim.
Personalisation through AI
Previously, phishing attacks relied on a generic mass message sent to thousands, hoping some of the recipients would fall for the bait. AI has changed this into scripting highly personalised phishing emails in large numbers. Using publicly available information like that on social media, job boards, and companies’ websites, these AI-powered tools can generate emails tailored to an individual’s role, interests, and communication style.
For example, a CFO might receive a fraudulent email that mirrors the tone and formatting of their CEO’s messages, including accurate references to recent company events. This level of customisation makes it exceptionally challenging for employees to distinguish between legitimate and malicious communications.
Deepfake technology
AI has also introduced deepfakes into the phishing arsenal. These are increasingly being leveraged by cybercriminals to create fake but highly accurate audio and video messages, crafted to reflect the voice and appearance of the executives they seek to impersonate.
For example, in one reported case, attackers used a deepfake to impersonate multiple members of staff during a video conference, convincing the employee to transfer approximately $25.6 million. As deepfake technology continues to advance, it is expected that such attacks will become more frequent and harder to detect.
Bypassing traditional defenses
Cybercriminals can manipulate the script of traditional e-mail filtering systems with the use of AI. By analysing and mimicking legitimate email patterns, AI-generated phishing emails can bypass security software detection. Machine learning algorithms can test and refine phishing campaigns in real time, enhancing their success rates and making them increasingly sophisticated.
Why experience is not enough
Even experienced employees are falling victim to these advanced phishing attacks. The level of realism and personalisation that AI can achieve may override the skepticism that keeps experienced professionals cautious. Moreover, AI-generated attacks often exploit human psychology, such as urgency, fear, or authority, pressuring employees into acting without double-checking the authenticity of the request.
Combatting AI-hyped phishing
To defend against AI-driven phishing attacks, organisations must adopt a proactive and multi-layered approach that emphasises comprehensive cybersecurity. Regular, up-to-date AI-focused cybersecurity awareness training is critical for employees, helping them identify the subtle signs of phishing and other malicious tactics.
Kaspersky Automated Security Awareness Platform can help with such training. Alongside this, businesses should implement robust security tools, such as Kaspersky Next and Kaspersky Security for Mail Server, capable of detecting anomalies in emails, such as unusual writing patterns or suspicious metadata.
A zero-trust security model also plays a vital role in minimising the potential damage of a successful attack. By restricting access to sensitive data and systems, this approach ensures that even if attackers breach one layer of security, they cannot compromise the entire network. Together, these measures create a comprehensive defense strategy, combining advanced technology with vigilant human oversight.

10 Percent of Nigerians Affected by Data Breaches since 2004

At least 10 out of every 100 Nigerians have fallen victim to data breaches since 2004, according to a new report by global cybersecurity firm Surfshark, raising serious concerns about the country’s long-standing vulnerability to cyber threats.
Surfshark’s research is based on data gathered from 29,000 publicly available databases.
Each unique breached email address is treated as a separate user account, and breaches often include additional personal data such as passwords, phone numbers, IP addresses, and postal codes.
The data was anonymised before analysis, and countries with populations under one million were excluded from the study.
Findings of the report revealed that a staggering 23.2 million Nigerian user accounts have been compromised in the past two decades, an alarming figure in a country with an estimated population of over 230 million.
This includes 7.3 million unique email addresses and 13 million passwords leaked into the public domain.
“Cyberattacks remain a persistent and growing threat globally, and Nigeria is no exception,” Surfshark stated in its analysis.
Despite a significant 85 per cent drop in new data breaches in the first quarter of 2025, falling from the previous quarter’s numbers—Nigeria still recorded over 119,000 breached accounts during the period. This places the country 34th worldwide in total breach volume.
Even with the recent decline, the scale and depth of past breaches remain troubling.
According to the report, 56 percent of Nigerian users affected by breaches are at heightened risk of identity theft, extortion, and unauthorised access to their online accounts.
“In Q1 2025 alone, an estimated one Nigerian account was breached every minute,” Surfshark noted.
The global picture also shows a dramatic shift: the number of leaked accounts dropped 93 percent year-on-year—from nearly 974 million in Q1 2024 to just 68.3 million in Q1 2025.
Countries with the highest number of breaches include the United States (16.9 million), Russia (4.4 million), and India (4.2 million).
However, when adjusted for population, smaller nations like South Sudan, Spain, and Slovenia reported the highest breach density, with South Sudan recording 61 breached accounts per 1,000 residents.
Luís Costa, Surfshark’s research lead, warned that the downturn in breach numbers should not lead to a false sense of security.
“Cyberthreats are constantly evolving, and attackers are adapting their tactics. Strong security practices, frequent password updates, and enabling two-factor authentication remain essential,” Costa stated.
The report underscores the urgent need for improved cybersecurity infrastructure and public awareness in Nigeria, as millions remain exposed to potential exploitation due to past breaches.
