The most online generation is also the least protected: over half of Gen Z have already faced a cyberattack – Adaderana Biz English

New research from Kaspersky surveyed 7,200 respondents globally and found that Generation Z spends 57% of their time online, primarily using smartphones (67% identify them as their main device). While 59% of Gen Z feel confident in navigating the digital landscape, only 28% consider their digital skills advanced. Alarmingly, only 27% use antivirus software on their mobile devices, and over half (52%) have encountered attacks on their devices or accounts. Significant data, such as personal photographs (38%) and passwords (30%), is stored on smartphones, yet only 28% regularly back up important data. Kaspersky recommends integrating cybersecurity into daily routines and has introduced an interactive game, “Case 404,” to educate Gen Z on recognizing digital threats.

Why Antivirus Alone No Longer Protects Small Businesses

Many small businesses have historically relied on antivirus software for computer security, which was effective against identifiable malware. However, the current cyber threat landscape includes sophisticated attacks such as phishing, credential theft, and ransomware that traditional antivirus solutions may not adequately address. Factors driving increased cyber threats in Kenya include phishing, weak authentication practices, delayed software updates, and the use of artificial intelligence by malicious actors. While antivirus software can detect known malware and block common threats, it falls short against tactics like stolen credentials and social engineering. The Communications Authority recommends complementing antivirus with multi-factor authentication, regular software updates, secure configurations, and user training. Endpoint Detection and Response (EDR) solutions enhance visibility into attacks by monitoring endpoint activity for suspicious behaviors, allowing for prompt investigation and response. A layered security strategy that integrates multiple protective measures is essential for effective cybersecurity, and many modern security platforms offer unified solutions to simplify management for smaller organizations. The Kaspersky SMB Cybersecurity Guide provides insights into modern attack methods and the role of endpoint protection in improving a business's cybersecurity posture.

Telegram vs Jio: Messaging app founder alleges cyberattack, Reliance responds

Pavel Durov, the founder of Telegram, has raised concerns about accessibility issues on his platform, attributing them to a technique called "BGP hijacking," which redirects internet traffic. He alleges that these disruptions affect users beyond India, including in the UAE, and suggests that Reliance Jio, an Indian telecom operator partly owned by Meta, may be involved in sabotaging access to Telegram. Reliance Jio has denied these allegations, stating they operate in accordance with global internet routing best practices. BGP hijacking occurs when a network falsely claims to be the preferred route, causing disruptions in internet traffic. There are indications that the network in question may be linked to Reliance Communications rather than Reliance Jio. The situation is complicated by a temporary block on Telegram in India due to the platform allegedly being used for leaking examination materials.

Hackers Can Hide Malware Inside Images to Hack Windows

Researchers at Cyfirma have identified a cyberattack campaign named Operation SilentCanvas that targets Windows systems using deceptive JPEG files to infiltrate devices. The attack begins with victims receiving a file named sysupdate.jpeg, which contains a PowerShell script instead of an image. This script establishes staging environments and downloads additional malicious components while avoiding detection. The malware reconstructs command strings at runtime and downloads a secondary payload called access.jpeg, executed in memory. It exploits Microsoft's .NET compiler to create a custom launcher named uds.exe on infected machines. The malware takes control of a registry key to create a hidden desktop environment for undetected execution of malicious tools and installs a persistent Windows service, OneDriveServers, to maintain activity after reboots. Additionally, it can intercept usernames and passwords at the Windows login screen and create hidden local administrator accounts for long-term access. Security teams are advised to monitor the execution of commonly abused Windows binaries like csc.exe and ComputerDefaults.exe to mitigate risks.

Binance’s Android app is quietly running TikTok and WeChat SDKs alongside 13 other trackers

Security researchers have found that the Binance Android app includes SDKs from ByteDance and Tencent, along with 13 additional third-party trackers. This raises privacy concerns for users, as the TikTok SDK collects device fingerprints, behavioral signals, and potentially clipboard data, while the WeChat SDK adds functionalities not necessary for a financial trading platform. The incorporation of these SDKs could expose sensitive financial information. Under EU GDPR and FTC regulations, undisclosed telemetry in financial apps may be considered deceptive trade practices, potentially leading to regulatory repercussions for Binance. Users are advised to revoke permissions from the app or switch to the browser-based platform. The situation could prompt regulatory scrutiny and audits of cryptocurrency asset management apps.

WhatsApp Malware Campaign Uses VBS to Hijack Windows

Microsoft has identified a cyberattack campaign that uses WhatsApp messages to distribute malicious Visual Basic Script (VBS) files targeting Windows systems. First detected in late February 2026, the campaign employs social engineering to trick users into executing the VBS files, which then create hidden directories and disguise themselves as legitimate Windows utilities. The malware downloads additional payloads from cloud platforms like AWS, Tencent Cloud, and Backblaze B2 to establish persistence and escalate privileges. It can bypass User Account Control (UAC), alter registry settings, and install malicious MSI packages, including remote access tools like AnyDesk, to maintain continuous access for attackers.

ClickFix Lures Power LeakNet’s Growing Ransomware Attack Chain

The ransomware group LeakNet has evolved its tactics, increasing its average targets from three per month and shifting from purchasing stolen network access to launching its own campaigns. They now use deceptive error screens and a new tool that executes malicious code in a computer's memory. Their strategy includes ClickFix lures, which compromise legitimate websites to display fake security checks, tricking users into executing malicious commands. This method broadens their victim reach and reduces costs. The Deno loader, part of this strategy, collects machine information and retrieves additional malicious code without leaving standard files, making detection difficult. After infiltrating a network, LeakNet checks for active user credentials and uses PsExec for lateral movement, employing Amazon S3 buckets for payload staging and data exfiltration. Defenders are advised to monitor for suspicious behavior rather than just known malicious files, focusing on unusual web commands and unexpected cloud storage connections.

NordVPN Stopped Most Phishing Emails in Third-Party Testing, Study Says

NordVPN's Threat Protection Pro blocked 92% of phishing websites in an independent lab test conducted by AV-Comparatives, which evaluated 15 products against 250 verified phishing URLs. The test took place between January 7 and January 19, using Google Chrome for assessments. NordVPN's product ranked fourth, while the top three performers were Avast Free Antivirus and Norton Antivirus Plus (both at 95%) and Webroot SecureAnywhere Internet Security Plus (93%). The software provides protection against phishing attempts and malware infections, even when not connected to a VPN. Phishing attacks have surged by 4,151% since the introduction of ChatGPT in 2022, with companies facing significant financial losses per breach. AI is being used to enhance phishing tactics, including deepfake videos and voice impersonations. Despite its effectiveness, NordVPN's Threat Protection Pro cannot remove existing malware on devices.

Global Group ransomware gang running new campaign using Windows shortcut files

The Global Group ransomware operates entirely in silent mode, executing all activities locally on the compromised system without relying on a command and control server. It generates the encryption key directly on the host machine, resulting in no actual data exfiltration despite claims in its ransom note. This approach allows for quicker attacks, targeting a broader range of victims while reducing detection risk. The act of encryption alone can compel payment due to significant operational downtime for affected organizations.
