Whether you are within the confines of your home, trapped in traffic while driving or on the road, many spend a lot of time listening to music through their headphones.
In Nigeria, the in-ear variety are commonly used as they are a cheaper option – you can get it as low as N200 from street vendors. Also, they are much more portable than full-size headphone and easier to carry around.

The in-ear headphones however require maintenance. Aside from the fact that it can transmit bacteria from person to person if shared, and in some cases can cause ear infections, it requires regular cleaning for it to function properly and last a long time.

The sealed design increases the heat in the ear canal and leads to more ear wax and oils accumulating on the bud. These earwax, dust and debris can get trapped in the earphone nozzles and impact the sound quality of your headphones negatively.

If you have noticed a drop in the sound level of your earphones and chances are you need to clean them. Obviously, you cannot just dunk them in soapy water and shake them around so Jovago.com, in this article, therefore highlights techniques on how to keep your earphones clean

Step 1:
Detach the earphones from the device. Ensure you do not clean your earbuds when they are still connected to your gadgets or device.

Step 2:
Separate the earphones. Most earbuds come with removable (and replaceable) silicone covers, it is important to take them apart and and clean them separately.

Step 3:
Make a mix of dishwashing detergent and warm water soap. Ensure the mix is light and not too soapy or too hot. Too much soap could leave a residue on your earbuds.

Step 4:
Use a gentle cloth with just a small amount of the soap mixture to clean the ear phones. A cotton bud stick would be preferable. Remember not to soak in too much water, as that may damage the ear phones.

Step 5:
For the metal part of the earphones, use a soft-bristled toothbrush with hydrogen peroxide (maximum concentration, 3%) to dislodge the dust and remove the wax. Do allow excess hydrogen peroxide to enter the open port on the earbud.

Step 6:
Once the headphones are cleaned, gently shake out any excess liquid and debris, and dry the earbud with a soft cloth, or allow them to air dry.  Once dry without any form of dampness, put the parts back together and it is ready to be used again.

Nigeria Mulls National Cybersecurity Council

Published

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.

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

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

Published

Kindly share this post

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.
