Online Tool Tracks Insecticide Resistance in Mosquitoes
IR Mapper, an interactive website, has made history as the first online mapping tool to track insecticide resistance in mosquitoes that cause malaria.
The interactive website identifies locations in more than 50 malaria-endemic countries where mosquitoes have developed resistance to the insecticides used in bed nets and indoor residual sprays.
IR Mapper incorporates the just-released World Health Organization (WHO) revised criteria for reporting insecticide resistance which is designed to detect it earlier.
With the most comprehensive and up-to-date information, the IR Mapper helps direct which vector control tools should be deployed in areas of high resistance.
Malaria is a deadly disease transmitted to people through infected mosquitoes. It kills a child every 60 seconds yet it is preventable and curable.
Progress has been made against the disease due largely to wide scale use of insecticide-treated bed nets and indoor residual spraying (IRS).
But the rapid spread of resistance in malaria-carrying mosquitoes to insecticides used in bed nets and sprays threatens current malaria control efforts.
Resistance among Anopheles malaria vectors has been reported in 64 countries, with parts of Sub-Saharan Africa and India of greatest concern.
“Deployment of the most appropriate insecticide based vector control interventions including nets and IRS needs to be informed by up-to-date data on insecticide resistance in the malaria vector species,” said Dr. Nabie Bayoh, an entomologist at KEMRI/CDC in Kisumu, Kenya.
“Until now, data has been scattered throughout different databases and has come from a variety of sources. This has made prompt decision-making difficult. IR Mapper has helped to address this” he added.
IR Mapper consolidates published data on insecticide susceptibility and resistance mechanisms from 1959 to 2012.
It includes reports from the President’s Malaria Initiative, National Malaria Control Programmes and other reputable institutes.
Resistance is usually measured by putting mosquitoes in a tube lined with insecticide-treated paper. Mosquitoes land on the paper and absorb the insecticide – some may die and some may survive. A population is considered susceptible if almost all die.
Until recently, resistance was confirmed by survival of more than 20 percent in this test.
The new guidelines from WHO reduced this threshold value to 10 percent, meaning that resistance will be reported earlier. This change is an indication of the concern insecticide resistance is causing globally.
IR Mapper data aligned with the new WHO thresholds is presented in a user-friendly format on interactive maps.
The mapping function allows filtering and projection of data based on a set of user-directed criteria. For instance, users can examine the resistance status of single or multiple Anopheles species to one or more insecticides within their region of interest.
This can be the basis for a “go” or “no go” decision on a particular insecticide for deployment on nets or in sprays. Data can also be viewed for specified time periods, to identify any existing trends in resistance over time.
Data consolidation for IR Mapper was conducted by Vestergaard Frandsen and KEMRI/CDC.

Nigeria Mulls National Cybersecurity Council

Federal Government has unveiled plans to establish a National Cybersecurity Coordination Council, signaling a shift toward a more unified, intelligence-driven approach to defending the country’s rapidly expanding digital economy.

Conceived as a non-statutory, multi-stakeholder body, the proposed Council will enhance coordination, enable trusted information sharing, and guide government strategy on cybersecurity, risk management, and national response amid increasingly complex cyber threats.
The initiative, championed by Bosun Tijani, minister of communications, innovation and digital economy, is designed to bring together government institutions, private sector players and technical experts into a single collaborative platform to strengthen the country’s cyber resilience.
Tijani noted that this initiative comes in response to a wave of recent cyber incidents that have disrupted operations across key private institutions and public sector.
In recent times, Nigeria’s financial system has faced mounting cyber pressure, reflecting global trends as cybercrime is projected to cost the world over $10.5 trillion annually, according to Cybersecurity Ventures.
Analysts say these attacks are increasingly coordinated and sophisticated, prompting the government to recognise that fragmented, institution-specific approaches can no longer manage systemic cyber risks effectively.
Under the new framework, the government aims to promote a “collective defence” model, an approach widely adopted in advanced digital economies where threat intelligence is shared in real time across institutions.
The Council is expected to include chief information security officers, cybersecurity associations, the Nigerian Computer Society, global technology providers, researchers, law enforcement agencies and civil society groups, ensuring a broad-based and technically grounded response architecture.
Key priorities will include developing national threat intelligence-sharing systems, harmonised cyber defence protocols, and coordinated incident response, while strengthening capacity to close Nigeria’s cybersecurity talent gap.

Oracle Sacks 12,000 in India, Begins Shift to AI

Oracle, US-based technology giant, has initiated a sweeping round of layoffs affecting thousands of employees globally, with India among the worst-hit regions, according to multiple reports.

The job cuts, which began on March 31, are part of a broader restructuring exercise that could impact between 20,000 and 30,000 employees worldwide, making it one of the largest workforce reductions in the company’s history.
While the exact number remains unconfirmed, multiple reports suggest that around 12,000 employees in India have been affected,
Employees across several geographies, including India, the United States, Canada, and Mexico, reported receiving termination emails early in the morning, informing them that their roles had been eliminated with immediate effect.
“Today is your last working day,” the email stated, citing “organisational change” as the reason for the decision. Access to company systems, including email and internal platforms, was revoked shortly thereafter.
The communication, according to Business Insider, described the move as part of a broader “reduction in force and other terminations,” and said affected employees would be eligible for severance benefits subject to company policy.
The email also instructed employees to share personal contact details to receive separation documents.
In India, impacted employees have reportedly been offered severance packages that include 15 days’ salary for each completed year of service, notice period pay, leave encashment, gratuity where applicable, and an additional two-month salary top-up in cases of voluntary separation.
The layoffs are linked to Oracle’s strategic shift towards artificial intelligence (AI) and cloud infrastructure.
The company has announced plans to invest approximately USD 50 billion in AI infrastructure and has reportedly raised an equivalent amount in debt to fund its expansion.
In a recent regulatory filing, Oracle said it expects restructuring costs for fiscal 2026 to reach up to USD 2.1 billion, largely driven by severance payouts and related expenses.
The move comes as Oracle looks to strengthen its position against global cloud competitors such as Amazon and Alphabet.
Uncertainty continues to loom over employees, with reports indicating that another round of layoffs could follow in the coming weeks. Employees who were affected described the layoffs as abrupt, with little prior indication.
Some former staff members have taken to social media to share their experiences.
Tricia S Marsh, a former Senior Principal at Oracle, said the layoffs marked the end of an important chapter in her career while urging affected colleagues to remain hopeful.
As of May 2025, Oracle had around 162,000 full-time employees globally.

Cybersecurity Firm Uncovers CrystalX RAT which Steals Data, Mocks its Victims

Kaspersky Global Research & Analysis Team (GReAT) has uncovered an active malicious campaign distributing a previously undocumented RAT with a very broad feature set. Beyond the standard remote access trojan functionality, it combines stealer, keylogger, clipper, and spyware capabilities.

Cybercriminals are selling it to third parties as MaaS (malware-as-a-service) promoting it on YouTube and Telegram, increasing the likelihood of its use across a wider range of actors, including less-skilled operators.
Due to its stealer functionality, the malware can collect a wide range of data about its victim: it gathers system information, extracts credentials for Steam, Discord and Telegram, and also harvests data from web browsers. It also poses a threat to cryptocurrency users, as it includes a browser-based clipper that replaces crypto wallet addresses.
Beyond data theft, CrystalX RAT is capable of full-scale surveillance, with the ability to take screenshots, record audio from the microphone, and capture video from both the webcam and the victim’s screen.
Particularly notable is the CrystalX RAT “playful” Prankware feature set, which is actively promoted by the developers. These capabilities allow operators to visibly interfere with the victim’s system by shaking the mouse cursor, setting wallpapers on the victim’s screen, changing screen orientation, hiding desktop icons, forcing system shut downs, and even delivering real-time pop-up notifications and messages to the victim.
While seemingly trivial, these features introduce a disruptive and psychological dimension to the attack, making the attack both visible and distressing for the victim.
Kaspersky reports attacks targeting users in Russia, but the trojan has the potential to spread to other countries due to its sales and distribution model.
“Such a diverse feature set effectively enables a 360-degree compromise of the victim and a complete loss of privacy. Beyond gaining access to account credentials, the stolen data could potentially be used for blackmail.
“At the moment, the initial infection vector is not precisely known, but it is already affecting dozens of victims. Our telemetry is already detecting new versions of the implants, indicating that this malware is still actively developed and maintained.
“We expect the number of victims to grow significantly and its geographic spread to expand in the near future,” says Leonid Bezvershenko, senior security researcher at Kaspersky GReAT.
