5 Steps to Protect Yourself from Cyberattacks While Working Remotely during Summer 2023 – Sophos
With the arrival of summer, teleworking becomes the priority option for many workers, but it is necessary to take into account the risks and threats involved in moving the workspace to a new location.
Before the pandemic, cybersecurity started to be considered as a fundamental area in a company. But it’s really after the implementation of teleworking during confinement and the cyberattacks that many companies suffered, due to the exposure of their devices, that IT teams are increasingly focused on raising awareness among their workers. The objective is clear, shield each access point to the business network and monitor it to avoid active threats, making remote work a secure and flexible option.
“At the time the health emergency arose, companies had to apply various measures to continue operating from home, but, although the crisis passed and companies returned to normality, teleworking has remained in many cases. In the first instance, it is the companies that are taking measures to increase their levels of cyber protection, but in addition to that, users can also take measures that accompany them and that allow them to telework from wherever they want while maintaining protection”, explains Chester Wisniewski, Field Sophos CTO.
Flexibility or family reconciliation are some of the advantages offered by this modality, so it is not surprising that it is an option that many workers choose for the summer season. Although at an operational level changing workplaces seems simple, it is important to take into account a protocol for prior actions. Cybersecurity experts at Sophos, a global leader in innovation and delivery of cybersecurity as a service, offer five steps to take to avoid risk and concern in what should be a happy and pleasant time:
1. Previous preparation. Just as you must prepare your devices and materials to establish your office in the new destination, you cannot forget to condition them internally, for this, check that your devices have the appropriate security software installed and that they comply with the compliance policies and security of your organization. solutions are patched and protected.
2. Training. Most cyberattacks start with a vulnerability in the weakest link in the chain, that is, the users. Workers can be the gateway used by attackers to access the rest of the company’s devices. This makes it necessary that, as a worker, it is important to acquire basic knowledge to know how current and identify in time if you are being attacked, either by your company or by your own account.
3. Double check. If you receive an unexpected communication from a coworker or business that seems out of the ordinary, don’t respond directly, rather contact the person or organization using another communications method like phone or SMS to ensure they are who they say they are.
4. Apply updates as soon as they are available. This is easiest on our phones and computers as we are usually prompted to update them, but don’t forget your internet router and smart home things. It is a good practice to check them all for available updates at least once a quarter.
5. Don’t forget to keep the “essentials”. Finally, despite carrying out all the previous steps, we must not forget the most basic protection measures that represent the entry barrier. First, set unique passwords for all your accounts and use a password manager to help keep them long and secure. Ideally, use multi-factor or “two-step” authentication wherever available to provide additional protection.
“Today most devices are used when connected to the internet, so you have to maintain a mindset where devices are considered to be in a hostile environment at all times. The idea that the safe space is inside offices and the insecure one outside is outdated. Now, anywhere you can suffer an attack, but it is true that sometimes when we move along with our workplace we do not take the necessary tools with us, so it is important to be vigilant”, adds Chester Wisniewski.
WhatsApp is launching three new ad features in a global roll-out across the messaging app.
The Meta-owned platform said the new ads will not be shown in the same place as people’s private chats, nor will the contents of their messages – which are encrypted – be used to decide which ads to display.
WhatsApp will instead use the country, city and language of the user, as well as how they interact with other ads and which channels they follow, to drive suggested content.
But people who have chosen to link their WhatsApp account to Facebook or Instagram will see more personalised ads.
The new ad features will appear in a section called Updates, which is a separate tab at the bottom of the app.
WhatsApp claims to have 1.5 billion users globally.
Businesses with channels will be able to choose to promote ads in the Updates section to attract new followers, and also charge a subscription to access extra content.
WhatsApp will eventually take a 10% commission of that fee, and there may also be extra costs on top of that taken at the app store level depending on the size of the business.
Firms will also be able to advertise in the form of a status update, which looks similar to an Instagram story and will link through to start a chat if clicked on.
Social media expert Matt Navarra told reporter that Meta is “laying the foundation for WhatsApp to finally become a monetisable platform at scale”.
But “monetising the periphery” of WhatsApp, while keeping personal chats private, would not be without risk for the company, he added.
This could particularly be the case in markets like the UK and Europe, he said, where the app is viewed primarily as a messaging tool with less appetite for content feeds or adverts.
“Any perception that the app is becoming noisy or Facebook-ified will spark backlash,” he said.
How does WhatsApp make money?
‘Natural extension’
It’s no coincidence that the new features bring WhatsApp more in line with Meta’s other platforms Facebook and Instagram.
“Obviously there’s overlap,” said WhatsApp boss Will Cathcart.
“We have stories on Instagram and stories on WhatsApp, and we now have a way for businesses to promote themselves in both, and we think that’s a good thing.”
He said he believed the move was a “natural extension of messaging services” and not dissimilar to features of rival apps such as Snapchat and Telegram.
For Mr Navarra, it also reflects a wider shift in the social media landscape.
“The feed is dying, public sharing is down, people are retreating into DMs and Stories in small groups,” he said.
“Meta’s trying to turn WhatsApp into a platform without users realising it and if they move too fast or it starts to feel like another ad network, people might disengage or maybe worse, distrust the app.”

The Association of Licensed Telecom Operators of Nigeria (ALTON) wishes to inform the public and all mobile subscribers that the migration to the End-User Billing (EUB) model for Unstructured Supplementary Service Data (USSD) services will take effect from Wednesday, 18th June 2025.
This transition marks a significant milestone in the evolution of Nigeria’s digital financial ecosystem and is being implemented per the Determination of USSD Pricing and Services issued by the Nigerian Communications Commission (NCC).
The Determination was developed in collaboration with the Central Bank of Nigeria (CBN) and other key stakeholders to ensure a sustainable, transparent, and customer-friendly framework for USSD service delivery.
USSD services play a vital role in expanding access to financial services, particularly for unbanked and underbanked populations. However, the previous corporate billing model—where banks were billed by telecom operators—led to prolonged disputes over unpaid charges, service interruptions, and uncertainty for customers.
To address these challenges, the NCC’s 2025 Determination introduced the End-User Billing model, which allows mobile network operators to charge customers directly for USSD sessions.
To achieve the implementation of the EUB model, the CBN and NCC have stipulated that only banks that meet certain regulatory and operational conditions are permitted to migrate. One of which is the notification to customers of the billing change in advance, and to ensure that customers are fully aware of the new airtime-based charges and how they will be applied.
Accordingly, under the new billing model, USSD charges will be deducted directly from the customer’s airtime balance, not from their bank account, and each USSD session will attract a charge of ₦6.98 per 120 seconds. To enjoy the service, customers will receive a prompt to opt in and approve the charge before any deduction is made, and there will be no double billing as billing will only occur for successful sessions via airtime deductions.
ALTON wishes to reiterate that this change does not affect the availability or functionality of USSD banking services, as customers can continue to use their bank’s USSD codes as usual, provided they have sufficient airtime.
To ensure a smooth transition, ALTON advises customers to follow these support guidelines:
–For access issues (e.g., inability to dial USSD codes), contact your mobile network operator.
– For transaction-related issues (e.g., failed transfers or service errors), contact your bank’s customer service.
– Both banks and mobile network operators are required to provide responsive support and mensure that customers can access and use USSD services without disruption.
Alternative digital banking channels such as mobile apps, internet banking, and ATMs remain fully operational and available for customer convenience.
ALTON reiterates its commitment to working closely with the NCC, CBN, financial institutions, and other stakeholders to ensure that this transition is seamless, equitable, and beneficial to all parties, especially the end users.
We remain dedicated to promoting transparency, operational efficiency, and consumer protection across Nigeria’s telecommunications and digital finance sectors.
