ESET Advises Nigerian Companies on ‘Jaff / WannaCryptor’ Ransomware

For any suspicious emails, ESET strongly advised “Do not open”, indicating the Company is aware of several ransomware outbreaks that stem from malicious emails that can be used to introduce threats to your system.
ESET identifies these threats as Filecoder.WannaCryptor and Filecoder.NLI (Jaff), and ESET detects and blocks these threats and their variants and advised readers to visit http://support.eset.com/kb59351/ for a list of best practices to stop these threats.
“There were reports from our offices across Europe on how fast the spread is and major hospitals, ISPs and Telecommunication companies have already fell victim of the attack. The malicious email campaign stems from the Necurs botnet and spreads the new ransomware at the rate of more than 5 million emails per hour and hitting computers across the globe,” Mr. Olufemi Ake, country manager, ESET Nigeria said in an email to Nigeria CommunicationsWeek at the weekend.
“Typically, once the victim is infected, their files are encrypted. Unlike the traditional ransomware which leaves a note of the amount required for payment, Jaff Filecoder would advise the victim to visit a payment portal via a Tor site to decrypt their valuable files, said Mr Ake.
ESET products can detect and block this malware.
As an existing ESET client, the Company strongly recommend that you follow the suggestions below to ensure the highest level of security on your computer:
Make sure that ESET Live Grid is enabled in your ESET product.
Make sure that your ESET software is upgraded to the latest version and has the latest Virus Signature Database updates.
Do not open attachments sent to you in emails from unknown senders. We also recommend that you avoid opening unsolicited email attachments from someone you know and trust.
Warn colleagues who frequently receive emails from external sources – for instance financial departments or Human Resources.
Regularly back up your data. In the event of infection, this will help you recover all data. Do not leave external storage used for backups connected to your computer to eliminate the risk of infecting your backups. If your system requires Windows Updates to receive the patch for this exploit, create new backups after applying the patch.
Disable or restrict Remote Desktop Protocol (RDP) access (see Remote Desktop Protocol best practices against attacks).
Disable macros in Microsoft Office.
If you are using Windows XP, disable SMBv1.

Kaspersky Discovers Vulnerability in Qualcomm Snapdragon Chips that can Lead to Data Loss & Device Compromise

Kaspersky ICS CERT discovered a hardware-level vulnerability affecting Qualcomm chipsets that are widely used in a range of consumer and industrial devices, including smartphones and tablets, car components, IoT devices and more.

The vulnerability resides in the BootROM – firmware embedded at the hardware level. Attackers could potentially get access to any data stored on the device or device sensors like camera and microphone, implement complicated attack scenarios and in some circumstances get full control of the device. The results of the research were presented at Black Hat Asia 2026.
The vulnerability affects Qualcomm MDM9x07, MDM9x45, MDM9x65, MSM8909, MSM8916, MSM8952 and SDX50 series and was reported to Qualcomm in March 2025. Qualcomm formally acknowledged the vulnerability in April 2025. It has been assigned a CVE-2026-25262. Other Qualcomm-based chips may be affected as well.
Kaspersky researchers explored the Sahara protocol, a low-level communication system used when a Qualcomm chip enters Emergency Download Mode (EDL) – a special recovery mode designed for repairing or restoring smartphones or other devices. Sahara acts as the first step that allows a computer to connect to the device and load software before the operating system on the device starts.
Kaspersky demonstrated that a security flaw in this process could allow an attacker with physical access to the target device to bypass key security protections in the chip, compromise the secure boot chain and, in some cases, deploy malicious applications and backdoors to the chip’s Application Processor, thus fully compromising the entire device.
For example, in cases when the target device is a smartphone or a tablet, the attacker can potentially get access to entered user passwords, and subsequently this opens further access to multiple types of sensitive user data, such as files, contacts, location, access to the devices’ camera and microphone, etc.
A potential attacker only needs a few minutes of physical access to a device to compromise it. Therefore, if a smartphone has been sent for repair or left unattended for a short time, one can no longer be sure it is not infected. Researchers warn that the threat extends beyond end-user scenarios to include potential compromise during the supply chain phase.
“Vulnerabilities like this may allow attackers to deploy malware that is difficult to detect and remove. In practice, this could enable covert data collection or influence device behaviour over extended periods of time.
“While a reboot might seem like an effective way to remove such malware, it cannot always be relied upon: compromised systems may simulate a reboot without actually resetting. In such cases, only a complete loss of power – including battery depletion – guarantees a clean restart,” comments Sergey Anufrienko, security expert at Kaspersky ICS CERT.
Kaspersky advises organisations and individual users to exercise strict physical security control over devices including at the supply, maintenance and decommissioning phases. A reboot of the device by cutting off the power supply to the affected chip (if available) or full battery discharge may help to get rid of the malware if it was installed.

Survey Shows Gaps in Cybersecurity Policies and Employee Commitment Leave Organisations Vulnerable

A recent Kaspersky survey entitled “Cybersecurity in the workplace: Employee knowledge and behaviour”, showed that 39% of professionals in the Middle East, Turkiye and Africa (META) region, consider cybersecurity rules in their company to be excessive or not fully appropriate.

While 7% noted that their organisations do not have cybersecurity rules or that they are not aware of them. These results show a disconnect between corporate cybersecurity policies and employee commitment to these rules, underscoring the risks associated with shadow IT and unmanaged device usage in the workplace.
Shadow IT is defined as the use of unauthorised software, devices, or services without IT oversight, and it has evolved into a critical business risk. While often driven by employee productivity needs, it creates blind spots for IT departments.
The rise of hybrid work environments, increased reliance on cloud-based tools and the spread of AI tools have accelerated this trend. Without robust cybersecurity management and oversight, organisations face heightened exposure to ransomware attacks, data leaks, and regulatory penalties.
19% of survey respondents in the META region said there are no policies regarding the use of non-corporate devices in their company. 35% of employees admitted that they can use their own devices to access business information, provided they have some type of cybersecurity protection, even consumer-grade software.
On the positive side, 21% said they can use their own device, but these must first pass more stringent corporate IT security checks; while 25% of respondents indicated that only devices provided by the IT function can be used for work purposes.
The situation is significantly better with permissions for employees to install software on corporate devices without IT department’s approval. 50% reported that only IT specialists in their company are allowed to install software, while in 31% of organisations only top management or designated users can do so. 11% of employees can install software that is approved by the IT team. However, 8% of respondents said that all users can install any software they need without IT agreement in their organisation.
At the same time 21% of professionals surveyed acknowledged that within the past year they installed software on their work devices without IT supervision. That highlights a persistent shadow IT challenge that continues to expose organisations to security vulnerabilities, compliance risks, and data breaches.
“Shadow IT is now a mainstream operational risk. When one in five employees installs software without IT oversight, it signals a policy gap. Many organisations already have security policies in place, but employee perception must also be considered.
Organisations should move beyond restrictive controls and instead implement intelligent, user-centric cybersecurity strategies that combine strategies that integrate technology with employee awareness and responsible use,” said Toufic Derbass, Managing Director for the META region at Kaspersky.

Microsoft Faces £1.7Bn Cloud Lawsuit in UK over Alleged Market Abuse

Microsoft is facing a £1.7 billion ($2.3 billion) class action lawsuit in the United Kingdom over allegations that it abused its dominant market position in cloud computing.

Microsoft
The case, filed before the Competition Appeal Tribunal, was brought by Maria Luisa Stasi on behalf of about 59,000 British businesses and organisations. It alleges that Microsoft unfairly imposed higher costs on customers running its Windows Server software on rival cloud platforms.
Stasi said the company’s practices have had a significant financial impact on both public and private sector organisations over several years.
In allowing the case to proceed, the tribunal ruled that it has a “reasonable prospect of success.” The judges noted that Microsoft is alleged to have abused its dominance in the paid server operating system market to undermine competition in the cloud services space.
If the claim succeeds, compensation for affected organisations is estimated to range between £1.7 billion and £2.1 billion.
Microsoft has rejected the allegations and confirmed it will appeal the ruling. A company spokesperson said the decision does not represent a final judgment on the claims and that it disputes the substance of the case.
The lawsuit comes as regulators in the UK and the European Union intensify scrutiny of Microsoft’s cloud business practices. UK authorities are currently assessing whether the company should be designated as having “strategic market status,” a move that would subject it to stricter competition rules.
