SophosLabs Research Warns “Designer Cyber Threats on the Rise”

Sophos, a global leader in network and endpoint security, today revealed SophosLabs research that indicates a growing trend among cybercriminals to target and even filter out specific countries when designing ransomware and other malicious cyberattacks.

The research includes information from millions of endpoints worldwide and is analyzed by the team at SophosLabs.

To lure more victims with their attacks, cybercriminals are now crafting customized spam to carry threats using regional vernacular, brands and payment methods for better cultural compatibility, according to Sophos.

Ransomware cleverly disguised as authentic email notifications, complete with counterfeit local logos, is more believable, highly clickable and therefore more financially rewarding to the criminal.

To be as effective as possible, these scam emails now impersonate local postal companies, tax and law enforcement agencies and utility firms, including phony shipping notices, refunds, speeding tickets and electricity bills.

SophosLabs has seen a rise in spam where the grammar is more often properly written and perfectly punctuated.

“You have to look harder to spot fake emails from real ones,” said Chester Wisniewski, senior security advisor at Sophos. “Being aware of the tactics used in your region is becoming an important aspect of security.”

Researchers also saw historic trends of different ransomware strains that targeted specific locations. Versions of CryptoWall predominantly hit victims in the U.S., U.K., Canada, Australia, Germany and France, TorrentLocker attacked primarily the U.K., Italy, Australia and Spain and TeslaCrypt honed in on the U.K., U.S., Canada, Singapore and Thailand.

The analysis also shows Threat Exposure Rates[1] (TER) for countries during the first three months of 2016. Although Western economies are more highly targeted, they typically have a lower TER. Nations ranked with the lowest TER include France at 5.2 percent, Canada at 4.6 percent, Australia at 4.1 percent, the U.S. at 3 percent, and the U.K. at 2.8 percent..

The African countries were at an average level, Tanzania – 11.1 percent Kenya – 11.5 percent South Africa – 11.6 percent Egypt – 12.4 percent Angola – 15.7 percent Nigeria – 15.7 percent Tunisia – 16.4 percent Morocco – 16.6 percent Uganda – 24.9 percent Ghana – 25.5 percent Mozambique – 28.3 percent Algeria – 30.7 percent Zambia – 35.5 percent and Malawi – 39.4 percent.

Algeria at 30.7 percent, Bolivia at 20.3 percent, Pakistan at 19.9 percent, China at 18.5 percent and India at 16.9 percent are among countries with the highest percentage of endpoints exposed to a malware attack

“Even money laundering is localized to be more lucrative. Credit card processing can be risky for criminals, so they started using anonymous Internet payment methods to extort money from ransomware victims,” said Wisniewski. “We have seen cybercrooks using local online cash-equivalent cards and purchasing locations, such as prepaid Green Dot MoneyPak cards from Walgreens in the U.S. and Ukash, which is now paysafecard, from various retail outlets in the U.K.”

Tweet This: “Designer” cyber threats on the rise with localized logos, language and payment methods, according to Sophos.

The concept of filtering out specific countries has also emerged as a trend.

“Cybercriminals are programming attacks to avoid certain countries or keyboards with a particular language,” said Wisniewski. “This could be happening for many reasons. Maybe the crooks don’t want attacks anywhere near their launch point to better avoid detection. It could be national pride or perhaps there’s a conspiratorial undertone to create suspicion about a country by omitting it from an attack.”

Banking is an example of how cybercriminals are using location-based malware to be more prosperous. Sophos research reveals historically how Trojans and malware used to infiltrate banks and financial institutions converges on specific regions:

Brazilian banker Trojans and variants pinpoint Brazil
Dridex is predominant in the U.S. and Germany
Trustezeb is most prevalent in German speaking counties
Yebot is popular in Hong Kong and Japan
Zbot is wider spread, but mostly in the U.S., U.K., Canada, Germany, Australia, Italy, Spain and Japan

“There is an entire cottage industry of uniquely-crafted Trojans just targeting banks in Brazil,” said Wisniewski.

With cybercriminals having a deliberate hand in creating threats that look authentic and are specifically targeted, it is more difficult to recognize malicious spam.

Home computer users are often a target of these attacks and should protect their systems from sophisticated malware threats. Free enterprise-grade security software that can detect threats and protect both Mac and PC for the home user is available from Sophos Home.

This research and analysis is from SophosLabs, a network of security experts across the world who detect and track all types of Internet breaches 24/7/365 worldwide, including computer viruses, advanced malware and Trojans, spam, web threats, hack attacks and more.

SophosLabs receives and investigates millions of emails, URLs, files and other data points daily and leverages its extensive expertise within the group to develop new definitions that detect entire classes of threats and new variants.

With facilities strategically located in Australia, Hungary, U.K. and Canada, SophosLabs experts also monitor and determine threat trends and maintain malware, spam and web threat dashboards in real time.

More than 100 million users in 150 countries rely on Sophos’ complete security solutions as the best protection against complex threats and data loss.

Simple to deploy, manage, and use, Sophos’ award-winning encryption, endpoint security, web, email, mobile and network security solutions are backed by SophosLabs – a global network of threat intelligence centers.

Chams Holding Company Plc, (Chams Holdco), digital payments and verification firm, has created a new subsidiary which is expected to strengthen the push for Africa’s digital transformation.

Chams Carves Out Subsidiary to Support Africa’s Digital Transformation

The creation of the new subsidiary, ChamsCorp Plc, which took effect from February 1, was made known in a filing to the Nigerian Exchange Limited , according to an announcement.

Chams said that the new subsidiary, which is its 5th, will give a new dimension to its more than 40 years of work in building the digital ecosystem not only in Nigeria, but across the continent and the rest of the world.

The newly created company will focus on three major aspects, namely the manufacturing of digital devices and development of digital infrastructure and services; data center design, construction and operations, and the development and implementation of AI infrastructure and intelligent systems.

It will also contribute to its parent company’s digital ID, digital verification, and trust services offering.

“For nearly four decades, we’ve enabled trust in transactions and identity. Now, we go furthe”

Chams is expanding into AI, data centre infrastructure, and intelligent systems, building the backbone for Africa’s digital transformation,” the company wrote in a LinkedIn post.

“We are not just participating in the future. We are engineering it,” the message added.

According to the Chams announcement, a decision of its Board of Directors appointed members of the pioneer board of ChamsCorp Plc, with renowned banker Mohammed Bashir Yunusa designated as Chairman.

He is described as a well-known finance expert who specializes in deal structuring, corporate and retail finance, business strategy, digital transformation, and Islamic Finance and Banking.

With more than 10 years of experience in the financial services industry, Yunusa currently serves as head of Consumer and Digital Banking for Non-Interest Banking Retail at Sterling Bank Nigeria, and will also serve as a non-executive director on the board.

“Chamscorp is designed to take our most ambitious ideas to market at speed and scale. As Africa’s digital economy evolves, we are focused on delivering transformative solutions that empower governments, businesses, and citizens alike,” Femi Oyenuga, CEO, Chams, commented on the development.

Chams has over the years played a major role in contributing to Nigeria’s digital ID ecosystem development to facilitate access to financial services.

In 2023, the company Group Chairman publicly stated that in providing such digital services to the Nigerian government, it had incurred debts estimated at $100 million and were planning to change their business model as a result.

Nigeria, South Africa Drive Stablecoin Spending in Africa

Published

Kindly share this post

Africa has emerged as the global frontrunner in stablecoin adoption, with Nigeria and South Africa leading the charge with the fastest adoption rate, as transactions surge across the continent.

This is according to the Stablecoin Utility Report, compiled by YouGov on behalf of fintech firm BVNK.

The study, conducted in partnership with Coinbase and Artemis, surveyed over 4 600 early adopters and crypto-natives in 15 countries across five continents.

It shows people are turning to stablecoins to move money more quickly, securely and affordably – and how this shift in behaviour is becoming a worldwide trend beyond its roots in the Global South.

Stablecoin adoption is accelerating particularly rapidly across Africa in 2026, driven by currency volatility, high inflation and the need for cheaper, faster cross-border payments, it finds.

The Stablecoin Utility Report shows that 79% of African respondents hold stablecoins − the highest ownership rate globally − while 76% say they intend to acquire them in the near future.

Nigeria and SA lead the continent in everyday stablecoin spending, highlighting a shift from holding digital dollars as a store of value, to actively using them for commerce.

The appetite to be paid in stablecoins is even stronger: 95% expressed interest in receiving income via dollar-pegged digital assets, whether for salaries, freelance work or cross-border services, according to the study.

Anthony Yim, co-founder and CEO of crypto research firm Artemis, explains: “We’re experiencing a significant behavioural shift in the way people are using stablecoins.

“Crypto natives and early adopters are fully on board with stablecoins, using them to pay and be paid. This is driving mainstream, global adoption – stablecoin supply has increased 500% over the past five years. Alongside the passage of multiple legislation initiatives in numerous countries, it’s clear we’re experiencing a tipping point.”

From hedge to household spending

Unlike in some developed markets where stablecoins are viewed primarily as a payments upgrade, African users are deploying them as practical financial tools. Key use cases include hedging against inflation, facilitating remittances and funding day-to-day purchases.

The report finds that 92% of African respondents say the condition of their national economy directly affects their stablecoin usage − a reflection of currency volatility, capital controls and high remittance costs across several markets.

Africa also recorded the highest likelihood globally (89%) of users adopting stablecoin-linked debit cards, signalling demand for tighter integration between digital assets and traditional payments.

Infrastructure, not ideology

Taken together, the findings reinforce a broader thesis: stablecoins are evolving beyond a payment method into payments infrastructure, states the report.

For individuals, this means receiving income faster and at lower cost. For businesses, it enables borderless treasury operations and supplier payments. For financial platforms, it opens opportunities to embed stablecoin wallets, debit cards and cross-border settlement into core offerings.

This demand for institutional-grade integration is evident globally, with 77% of survey respondents saying they would open a stablecoin wallet if offered by their primary bank or fintech provider.

As adoption deepens in Africa and regulatory frameworks mature in developed markets, the data suggests stablecoins are no longer a niche crypto product − but a structural layer in the future of global money movement, notes BVNK.

Kaspersky Reports 15% Growth in Malicious email Attacks in 2025

Published

on

Kindly share this post

According to Kaspersky telemetry, almost every second email – 44.99% of global traffic – was spam in 2025. Spam consists not only of unsolicited emails, but can also include various email threats such as scam, phishing and malware.

In 2025, individuals and corporate users encountered over 144 million malicious and potentially unwanted email attachments, representing a 15% increase compared to the previous year figures.

In 2025, APAC had the largest share of email antivirus detections: it reached 30%, followed by Europe with 21%. Next came Latin America (16%) and the Middle East (15%), Russia and CIS (12%) and Africa (6%). As for individual countries, China had the highest rate of malicious and potentially unwanted email attachments, with the share of email antivirus detections of 14%. Russia ranked second (11%), followed by Mexico (8%), Spain (8%) and Turkey (5%).

Email antivirus detections peaked moderately in June, July and November.

Key trends in email spam and phishing

Kaspersky’s annual analysis has also identified several persistent trends in the email spam and phishing threat landscape that are expected to continue into 2026:

  • Combination of various communication channels. Attackers lure email users into switching to messengers or calling fraudulent phone numbers. For instance, scam investment mailings may redirect victims to fake websites, where they are asked to provide their contact information, and then cybercriminals will follow up with a phone call.
  • Usage of diverse evasion techniques in phishing and malicious emails. Threat actors frequently try to disguise phishing URLs, for example, with the help of link protection services and QR codes. These QR codes are often embedded directly in email bodies or within PDF attachments, which not only conceals phishing links but also encourages users to scan them on mobile devices, potentially exploiting weaker security measures than corporate PCs.
  • Mailings exploiting diverse legitimate platforms. For example, Kaspersky experts discovered a fraudulent tactic that abuses OpenAI’s organisation creation and team invitation features to send spam emails from legitimate OpenAI addresses, potentially tricking users into clicking scam links or dialing fraudulent phone numbers. Additionally, a calendar-based phishing scheme, which originated in the late 2010s, resurfaced last year with a focus on corporate users.
  • Refining tactics in business email compromise (BEC) attacks. In 2025 attackers attempted to become even more persuasive by incorporating fake forwarded emails into their correspondence. These emails lacked thread-index headers or other headers, making it difficult to verify their legitimacy within an email conversation. 

“Email phishing shouldn’t be underestimated. Our report reveals that one in ten business attacks starts with phishing, with a significant proportion being Advanced Persistent Threats (APTs). In 2025, we saw an increase in the sophistication of targeted email attacks. Even the smallest details are meticulously crafted in these malicious campaigns, including the composition of sender addresses and the tailoring of content to real corporate events and processes.

“The commodification of generative AI has significantly amplified this threat, enabling attackers to craft convincing, personalised phishing messages at scale with minimal effort, automatically adapting tone, language and context to specific targets,” comments Roman Dedenok, anti-spam expert at Kaspersky.
