Cybercriminals are exploiting a vulnerability in a Microsoft-signed driver developed by Paragon Software, known as BioNTdrv.sys, to carry out ransomware attacks. This driver, part of Paragon Partition Manager, is typically used to manage hard drive space, but hackers have found a way to misuse it for malicious purposes.
How the Attack Works
The vulnerability, identified as CVE-2025-0289, allows attackers to use a technique called "bring your own vulnerable driver" (BYOVD). This means they introduce the legitimate but flawed driver into a system and exploit it to gain high-level access. Once they obtain SYSTEM-level privileges, they can execute ransomware, steal data, or disable security software without being detected.
The alarming part is that the vulnerability can be exploited even on devices that do not have Paragon Partition Manager installed, as long as the driver exists on the system.
Other Vulnerabilities
Researchers also found four additional flaws in the driver:
1. CVE-2025-0288: Allows access to kernel memory, helping attackers gain control.
2. CVE-2025-0287: Can crash the system using a null pointer error.
3. CVE-2025-0286: Enables attackers to execute malicious code in kernel memory.
4. CVE-2025-0285: Allows manipulation of kernel memory, escalating control.
Response from Microsoft and Paragon
Microsoft confirmed that hackers are already using this flaw to spread ransomware and has responded by blocking the vulnerable driver through its Vulnerable Driver Blocklist. Meanwhile, Paragon Software has released a security patch and advised users to update their drivers immediately to avoid potential risks.
How to Stay Safe
To protect your system from these attacks:
1. Update your drivers from Paragon Software to the latest version.
2. Install Windows security updates regularly.
3. Use reliable antivirus software to detect suspicious activities.
4. Monitor your system for unexpected crashes or slow performance.
While Microsoft and Paragon Software have taken steps to contain the damage, users must stay proactive in securing their systems through regular updates and vigilant monitoring.
Poland’s space agency, POLSA, has reported a cyberattack on its systems, prompting an ongoing investigation. In response to the breach, the agency quickly disconnected its network from the internet to prevent further damage. As of Monday, its official website was still offline.
Government and Cybersecurity Teams Take Action
Poland’s Minister of Digital Affairs, Krzysztof Gawkowski, confirmed that cybersecurity experts detected unauthorized access to POLSA’s systems. Security specialists have since secured the affected infrastructure and are now working to determine who was behind the attack. However, officials have not yet shared whether the hackers were financially motivated cybercriminals or politically driven groups. The method used to infiltrate the agency’s network also remains undisclosed.
Why Hackers Target Space Agencies
Organizations involved in space research and technology are often appealing targets for cybercriminals. Many of these agencies collaborate with defense and intelligence sectors, making them vulnerable to attacks that could expose confidential projects, satellite communications, and security-related data. A cyberattack on such an agency could disrupt critical operations, leak classified research, or even interfere with national security.
Poland Faces a Surge in Cyberattacks
Poland has become one of the most frequently targeted countries in the European Union when it comes to cyber threats. Earlier this year, Gawkowski stated that the country experiences more cyber incidents than any other EU nation, with most attacks believed to be linked to Russian actors. Poland’s strong support for Ukraine, both in military assistance and humanitarian aid, has likely contributed to this rise in cyber threats.
The number of cyberattacks against Poland has increased drastically in recent years. Reports indicate that attacks doubled in 2023 compared to previous years, with over 400,000 cybersecurity incidents recorded in just the first half of the year. In response, the Polish government introduced a cybersecurity initiative in June, allocating $760 million to strengthen the country’s digital defenses.
Other Space Agencies Have Also Been Targeted
This is not the first time a space agency has fallen victim to cyberattacks. Japan’s space agency, JAXA, has faced multiple breaches in the past. In 2016, reports suggested that JAXA was among 200 Japanese organizations targeted by suspected Chinese military hackers. In 2023, unknown attackers infiltrated the agency’s network, raising concerns that sensitive communications with private companies, such as Toyota, may have been exposed.
As space technology continues to advance, protecting space agencies from cyber threats has become more crucial than ever. These organizations handle valuable and often classified information, making them prime targets for espionage, sabotage, and financial cybercrime. If hackers manage to breach their systems, the consequences could be severe, ranging from stolen research data to disruptions in satellite operations and defense communications.
POLSA’s ongoing investigation will likely uncover more details about the cyberattack in the coming weeks. For now, the incident highlights the increasing need for governments and space organizations to invest in stronger cybersecurity measures to protect critical infrastructure.
Users in Russia faced an internet outage in a targeted DDoS attack on Russian telecom company Beeline. This is the second major attack on the Moscow-based company in recent weeks; the provider has over 44 million subscribers.
After several user complaints and reports from outage-tracking services, Beeline confirmed the attack to local media.
According to Record Media, internet monitoring service Downdetector’s data suggests “most Beeline users in Russia faced difficulties accessing the company’s mobile app, while some also reported website outages, notification failures and internet disruptions.”
Beeline informed about the attack on its Telegram channel, stressing that the hacker did not gain unauthorized access to consumer data. Currently, the internet provider is restoring all impacted systems and improving its cybersecurity policies to avoid future attacks. Mobile services are active, but users have cited issues using a few online services and account management features.
The targeted attack on Beeline is part of a wider trend of cyberattacks in Russia; in September 2024, VTB, Russia’s second-largest bank, faced similar issues due to an attack on its infrastructure.
These attacks highlight the rising threats posed by cyberattacks cherry-picking critical infrastructures in Russia and worldwide.
Experts have been warning about the rise in intensity and advanced techniques of such cyberattacks, damaging not only critical businesses but also essential industries that support millions of Russian citizens.
How Beeline responds to the attack and recovers will be closely observed by both the telecom industry and regulators. The Beeline incident is similar to the attack on Russian telecom giant Megafon, another large-scale DDoS attack happened earlier this year.
According to a cybersecurity source reported by Forbes Russia, the Beeline attack in February and the Megafon incident in January are the top hacktivist cyberattacks aiming at telecom sectors in 2025.
According to the conversation with Forbes, the source said, “Both attacks were multi-vector and large-scale. The volume of malicious traffic was identical, but MegaFon faced an attack from 3,300 IP addresses, while Beeline was targeted via 1,600, resulting in a higher load per IP address.”
Ransomware remains a major problem for businesses, and a new cybercriminal group is expanding at an alarming rate. Security researchers at ReliaQuest have identified BlackLock as the fastest-growing ransomware operation today, with its activity increasing by 1,425% since late 2024. Although it is currently the seventh most active ransomware group, experts predict it could become the biggest threat in 2025.
Despite law enforcement cracking down on major ransomware gangs like LockBit in 2024, the number of cyberattacks continues to grow. A report from January 31 suggested ransomware incidents had risen by 15% compared to the previous year. However, a February 20 study by Symantec showed a slower increase of just 3%. No matter the rate, the takeaway is the same, ransomware remains a serious risk.
How BlackLock Ransomware Operates
BlackLock ransomware is designed to infect Windows, Linux, and VMware ESXi systems, making it a versatile and dangerous threat. Cybercriminals behind this operation have developed unique methods to pressure victims into paying ransom quickly.
1. Blocking access to stolen data
2. Recruiting criminals to assist with attacks
Steps to Protect Your Systems
Security experts recommend taking immediate action to strengthen defenses, especially for companies using VMware ESXi servers. Here are some key steps:
1. Turn off unnecessary services
2. Strengthen security restrictions
3. Limit network access
Additional recommendations include:
1. Activating multi-factor authentication (MFA) to prevent unauthorized logins.
2. Disabling Remote Desktop Protocol (RDP) on systems that do not need remote access.
The rapid rise of BlackLock ransomware shows that cybercriminals ar constantly developing new strategies to pressure victims and avoid detection. Organizations must take proactive steps to secure their networks and stay informed about emerging threats. Implementing strong security controls today can prevent costly cyberattacks in the future.
A cybercriminal group known as Fog Ransomware has claimed responsibility for a cyberattack on the University of Notre Dame in Perth, Australia. According to reports, the group has allegedly stolen 62.2GB of sensitive data, including student medical records, staff and student contact information, and confidential documents.
The university was first alerted to a cybersecurity breach in January 2025. Recently, technology news sources revealed that Fog Ransomware had posted details of the attack on its dark web leak site. The group claimed to have accessed and stolen a large amount of private and institutional information.
As of now, the hackers have not made any ransom demands or issued a deadline for payment. Cybersecurity experts believe that this group has a history of targeting educational and recreational institutions worldwide.
The cyberattack has disrupted essential university operations, making it difficult for students and staff to access key services. Some of the areas impacted include:
1. Payroll and leave management – Employees have been unable to process payments and leave applications as usual. Temporary manual processes have been put in place.
2. Student enrolments and timetables – Many students have struggled to access their class schedules and register for courses.
3. Communication services – Internet and email systems have also been affected, causing delays in official university communication.
University official Patrick Hampton, who is both the Deputy Head of Education and President of the National Tertiary Education Union WA Notre Dame branch, stated that the attack had disrupted critical functions necessary for the university’s daily operations. He also emphasized that staff and students need additional support to cope with these challenges.
At this stage, the university has not been able to confirm exactly what data has been stolen. A spokesperson explained that while primary systems handling student records, finance, and human resources appear secure, some separately stored data might have been compromised.
To assess the situation, the university has engaged international cybersecurity experts and is working to determine the extent of the breach. Officials have assured that if any personal data is found to be affected, the university will notify those impacted as soon as possible.
The incident has been reported to the Australian Cyber Security Centre (ACSC), and the university is taking necessary precautions to strengthen its security measures. Despite the ongoing challenges, the university has confirmed that classes for the 2025 academic year will begin as scheduled.
Meanwhile, the staff union is pushing for greater transparency from the university administration. They are demanding that university leadership keep staff and students fully informed about what data has been compromised and provide assurances about data protection measures moving forward.
This attack is a reminder of the increasing cybersecurity threats faced by educational institutions. Universities hold vast amounts of sensitive student and staff data, making them prime targets for cybercriminals.
A dangerous security flaw has been discovered in Exim, a widely used email server software. The vulnerability, officially tracked as CVE-2025-26794, allows hackers to inject harmful commands into the system, potentially leading to data theft or even complete control over the email server. This issue affects Exim version 4.98 when used with a specific database system called SQLite. Experts warn that this is one of the biggest email security threats of 2025.
How This Vulnerability Works
The problem occurs because of the way Exim handles database queries under certain settings. It mainly affects systems that:
1. Use SQLite for storing email-related data – This happens when Exim is set up with a special feature called `USE_SQLITE`.
2. Enable the ETRN command – This is a function that allows users to request email deliveries, but it can be misused if not properly restricted.
3. Have weak protections against command execution – Some default settings make it easier for attackers to sneak in harmful database commands.
If all these conditions are met, a hacker can send specially designed emails to the server, tricking it into running unauthorized commands. This could allow them to access sensitive information, modify system settings, or even take control of the entire email system.
How Attackers Can Use This Flaw
For this security risk to be exploited, three things need to be true:
1. The system must be running Exim 4.98 with SQLite enabled.
2. The ETRN command must be set to "accept" instead of the safer "deny" mode.
3. A specific security setting, smtp_etrn_serialize, must be left at its default value, which can create a loophole for hackers.
Even though Exim’s default settings provide some level of security, many organizations adjust them to work with older systems, unknowingly making their servers more vulnerable.
Steps to Stay Safe
To protect email systems from this issue, cybersecurity experts recommend taking the following steps immediately:
1. Check which version of Exim is installed using the command `exim -bV`.
2. Disable SQLite integration if it’s not necessary.
3. Modify ETRN settings to prevent unauthorized use.
4. Update to the latest Exim version (4.98.1), which includes a fix for this problem.
For organizations that must continue using SQLite, additional security measures should be in place, such as filtering out risky commands and monitoring unusual activity in the database.
How Exim Developers Responded
The Exim development team acted quickly by releasing a patched version within 72 hours after confirming the issue. The flaw was originally reported by cybersecurity researcher Oscar Bataille, who followed responsible disclosure guidelines. This allowed Exim’s developers to fix the problem before it became public, reducing the chances of widespread attacks.
Why This Matters
Exim is used by over 60% of email servers on the internet, meaning this flaw could have affected millions of systems worldwide. This incident is a reminder that even well-established software can have hidden weaknesses, especially when newer features interact with older components.
To stay safe, organizations must regularly update their email software, follow security best practices, and stay informed about new threats. The faster vulnerabilities like this are addressed, the lower the risk of cyberattacks.
