WannaCry: Kaspersky Records Over 45,000 Attacks in One Day

Barely a week ago, the world, saw the beginning of the Trojan encryptor WannaCry outbreak. It appears to be pandemic — a global epidemic.

“We counted more than 45,000 cases of the attack in just one day, but the true number is much higher,” Kaspersky writes in a blog post.

Recall several large organizations reported an infection simultaneously. Among them were several British hospitals that had to suspend their operations. According to data released by third parties, Kaspersky said that WannaCry has infected more than 200,000 computers. The sheer number of infections is a big part of the reason it has drawn so much attention.

The largest number of attacks occurred in Russia, but Ukraine, India, and Taiwan have suffered much damage from WannaCry as well. In just the first day of the attack, we found WannaCry in 74 countries.

The creators of WannaCry have taken advantage of the Windows exploit known as EternalBlue, which relies on a vulnerability that Microsoft patched in security update MS17-010, dated March 14 of this year. By using the exploit, the malefactors could gain remote access to computers and install the encryptor.

Generally, WannaCry comes in two parts. First, it’s an exploit whose purposes are infection and propagation. The second part is an encryptor that is downloaded to a computer after it has been infected.

“The first part is the main difference between WannaCry and the majority of encryptors. To infect a computer with a common encryptor, a user has to make a mistake, for example by clicking a suspicious link, allowing Word to run a malicious macro, or downloading a suspicious attachment from an e-mail message. A system can be infected with WannaCry without the user doing anything.

“If you have the update installed, then this vulnerability no longer exists for you, and attempts to hack the computer remotely through the vulnerability will fail. However, researchers from Kaspersky Lab’s GReAT (Global Research & Analysis Team) would like to emphasize that patching the vulnerability will not deter the encryptor entirely. Therefore, if you launch it somehow (see the above on making a mistake), then that patch will do you no good.

“After hacking a computer successfully, WannaCry attempts to spread itself over the local network onto other computers, in the manner of a computer worm. The encryptor scans other computers for the same vulnerability that can be exploited with the help of EternalBlue, and when WannaCry finds a vulnerable machine, it attacks the machine and encrypts files on it.

“Therefore, by infecting one computer, WannaCry can infect an entire local area network and encrypt all of the computers on the network. That’s why large companies suffered the most from the WannaCry attack — the more computers on the network, the greater the damage.

WannaCry
“As an encryptor, WannaCry (sometimes called WCrypt or, for no discernable reason, WannaCry Decryptor) behaves like any other encryptor; it encrypts files on a computer and demands ransom to decrypt them. It most closely resembles a variation of the infamous CryptXXX Trojan.

“WannaCry encrypts files of various types (the full list is here) including office documents, pictures, videos, archives, and other file formats that potentially contain critical user data. The extensions of the encrypted files are renamed .WCRY, and the files become completely inaccessible.

“After this, the Trojan changes the desktop wallpaper to a picture that contains information about the infection and actions that the user supposedly has to perform to recover the files. WannaCry spreads notifications as text files with the same information across folders on the computer to ensure that the user receives the message.

“As usual, the actions entail transferring a certain amount of money, in bitcoins, to the wallet of the perpetrators. After that, they say, they will decrypt all of the files. Initially, cybercriminals demanded $300 but then raised the stakes to $600”, the blog post reads.

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

Published

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

Published

on

Kindly share this post

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 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 Faces £1.7bn Cloud Lawsuit in UK Over Alleged Market Abuse

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.
