Unpatched Systems, Software’s Exposes Business to Cyber Threats

Remember when Qantas, Australia’s flagship airline confirmed a cyberattack exposing data from its frequent flyer program and customer accounts. The data was upto 6 million, which is staggering in number. This means any kind of exploits are malicious programs designed to take advantage of bugs or vulnerabilities in unpatched software or operating systems to gain unauthorised access. When left unpatched, these weak points act as open doors for cybercriminals.

Kaspersky research shows that the share of exploits targeting critical vulnerabilities in operating systems reached 64% in Q2 2025 (up from 48% in Q1 2025), with third-party apps (29%) and browsers (7%) following.

Unpatched Systems, Software’s exposes Business to Cyber Threats

The breach originated from a third-party customer service platform, proving that even indirect systems can expose millions of records we all knew. This was a clear case how unpatched software’s but Qantas denied any of its service platform was vulnerable and there was no sign the platform was compromised.

Similarly 1.5 billion records across 760 global companies record exposed to data breach when Salesforce was hit and the hacking group claimed to have breached Salesforce through compromised integrations with third-party tools like Drift and SalesLoft, stealing huge amounts of CRM data. And as recent Salesloft Drift cyberattack may have also compromised some Google Workspace accounts.

The above case are all about software vulnerabilities when left unpatched. Latest data from cybersecurity and privacy company Kaspersky revealed that existing vulnerabilities in business networks continue to leave Malaysian enterprises exposed to cyberattacks.

Globally, in Q2 2025, the most common exploits targeted vulnerable Microsoft Office products with unpatched security flaws, according to Kaspersky’s findings. Its solutions detected the most exploits on the Windows platform for the following vulnerabilities:

  • CVE-2018-0802: Remote code execution vulnerability in the Equation Editor component
  • CVE-2017-11882: Another remote code execution vulnerability in Equation Editor
  • CVE-2017-0199: Vulnerability in Microsoft Office and WordPad allowing attackers to gain control of the system

The report also revealed that the top 10 most exploited vulnerabilities included both new zero-day flaws and older unpatched issues that organisations continue to overlook. A zero-day vulnerability is a software flaw discovered by attackers before the vendor is aware of it. As no patch exists at the time, zero-day attacks often succeed.

Key findings from Kaspersky reports to secure your unpatched systems

  • Increased Exploitation: In the first half of 2025, more Windows and Linux users encountered vulnerability exploits compared to the previous year.
  • Targeted Vulnerabilities: Common exploits in Q2 2025 targeted Microsoft Office products with unpatched security flaws, such as those in the Equation Editor (CVE-2018-0802 and CVE-2017-11882).
  • End of Support: The end of free support for Windows 10 means millions of users will no longer receive critical security patches, leaving their systems vulnerable to new threats.
  • High volume of attacks: Kaspersky solutions blocked over 700,000 exploits targeting Indian organizations in the first half of 2025, averaging more than 4,000 per day

Attackers increasingly use methods to escalate privileges and exploit weaknesses in digital systems. As the number of vulnerabilities continues to grow, it is very important to constantly prioritize patching known vulnerabilities and use software that can mitigate post-exploitation actions. CISOs should counter the consequences of exploitation by searching for and neutralizing command and control implants that can be used by attackers on a compromised system,” says Alexander Kolesnikov, a security expert at Kaspersky.

What Businesses can do to remain Secure from Cyber threats when systems are unpatched?

For legacy systems and applications there is a lack ongoing vendor support, leaving remote code execution vulnerabilities open for exploitation. These attacks enable full system control with little user interaction.

How to Fix:

Apply host-based intrusion prevention and patch virtualization and replace or containerize legacy apps. It is important to isolate critical workloads in secure enclaves as being in legacy catagory they are prone to any kind of cyber threats and intrusion.

Kaspersky reveals SharePoint ToolShell vulnerabilities stem from incomplete 2020 fix.

Kaspersky’s Global Research and Analysis Team (GReAT) discovered that the recently exploited ToolShell vulnerabilities in Microsoft SharePoint originate from an incomplete fix for CVE-2020-1147, first reported in 2020.

IntruceptLabs have published the security advisory https://intruceptlabs.com/2025/07/toolshell-zero-day-exploits-in-microsoft-sharepoint-enable-full-remote-takeover/ on 21st July 2025.

The SharePoint vulnerabilities have emerged as a major cybersecurity threat this year amid active exploitation. Kaspersky Security Network showed exploitation attempts worldwide, including in Egypt, Jordan, Russia, Vietnam and Zambia.

The attacks target organizations across government, finance, manufacturing, forestry and agriculture sectors. 

Two newly discovered zero-day vulnerabilities (CVE-2025-53770 and CVE-2025-53771) in Microsoft SharePoint Server are being actively exploited in the wild.

There is currently no patch available to plug this security hole, but Microsoft says that customers running on-premises SharePoint Servers can stop attackers from exploiting the vulnerability by configuring Antimalware Scan Interface (AMSI) integration in SharePoint and deploying Defender AV on all SharePoint servers.

Share point Vulnerabilities a major cyber threat

The SharePoint vulnerabilities have emerged as a major cybersecurity threat this year amid
active exploitation. Kaspersky Security Network showed exploitation attempts worldwide,
including in Egypt, Jordan, Russia, Vietnam and Zambia.

The attacks target organizations across government, finance, manufacturing, forestry and agriculture sectors. Kaspersky solutions proactively detected and blocked ToolShell attacks before the vulnerabilities were publicly disclosed.

Kaspersky GReAT researchers analyzed the published ToolShell exploit and found it alarmingly similar to the 2020 CVE-2020-1147 exploit.

This suggests that the CVE-2025- 53770 patch is, in fact, an effective fix for the vulnerability that CVE-2020-1147 attempted to address five years ago.
The connection to CVE-2020-1147 became evident following the discovery of CVE-2025- 49704 and CVE-2025-49706, patched on July 8. However, these fixes could be bypassed by adding a single forward slash to the exploit payload.

Once Microsoft learned of active exploitation of these vulnerabilities, they responded with comprehensive patches that addressed potential bypass methods, designating the vulnerabilities as CVE-2025-53770 and CVE-2025-53771.

The surge in attacks against SharePoint servers worldwide occurred during the window between initial exploitation and full patch deployment. Despite patches now being available for the ToolShell vulnerabilities, Kaspersky expects attackers will continue exploiting this chain for years to come.

“Many high-profile vulnerabilities remain actively exploited years after discovery —
ProxyLogon, PrintNightmare and EternalBlue still compromise unpatched systems today.

We expect ToolShell to follow the same pattern: its ease of exploitation means the public exploit
will soon appear in popular penetration testing tools, ensuring prolonged use by attackers,”
said Boris Larin, principal security researcher at Kaspersky GReAT.

Hackers Weaponizing AI Extension to steal Crypto Assets Through Malicious Packages

The amount of crypto  malware has doubled in the first quarter of 2025 as per research.

Kaspersky GReAT (Global Research and Analysis Team) experts have discovered open-source packages that download the Quasar backdoor and a stealer designed to exfiltrate cryptocurrency. The malicious packages are intended for the Cursor AI development environment, which is based on Visual Studio Code — a tool used for AI-assisted coding.

The fake extension, published under the name “Solidity Language,” had accumulated 54,000 downloads before being detected and removed.

What makes this attack particularly insidious is its exploitation of search ranking algorithms to position the malicious extension above legitimate alternatives.

How the Threat actors deceive the developers

During an incident response, a blockchain developer from Russia reached out to Kaspersky after installing one of these fake extensions on his computer, which allowed attackers to steal approximately $500,000 worth of crypto assets.

The threat actor behind these packages managed to deceive the developer by making the malicious package rank higher than the legitimate one. The attacker achieved this by artificially inflating the malicious package’s downloads count to 54,000.

After the malicious extension downloaded by the developer was discovered and removed from the repository, the threat actor republished it and artificially inflated its installation count to a higher number – 2 million, compared to 61,000 for the legitimate package.

The extension was removed from the platform following a request from Kaspersky.

The attackers leveraged the Open VSX registry’s relevance-based ranking system, which considers factors including recency of updates, download counts, and ratings. The attack infrastructure reveals a well-organized operation extending beyond this single incident.

In 2025, threat actors are actively publishing clones of legitimate software packages that, once installed, execute harmful payloads ranging from cryptocurrency theft to full codebase deletion.

The discovery leads us to think how cyber criminals take advantage of the trust inherent in open-source environments by embedding harmful code. All third-party code should be treated as untrusted until proven.

The threat actor behind these packages managed to deceive the developer by making the malicious package rank higher than the legitimate one. The attacker achieved this by artificially inflating the malicious package’s downloads count to 54,000.

After installation, the victim gained no actual functionality from the extension. Instead, malicious ScreenConnect software was installed on the computer, granting threat actors remote access to the infected device.

Using this access, they deployed the open-source Quasar backdoor along with a stealer that collects data from browsers, email clients, and crypto wallets. With these tools, the threat actors were able to obtain the developer’s wallet seed phrases and subsequently steal cryptocurrency from the accounts.
