Bitdefender Data Breach FTC Malicious actor Tech Firm Zero Day exploit

Organizations Struggle with Data Breach Disclosure

A recent survey conducted by cybersecurity firm Bitdefender highlights the ongoing struggle of organizations to handle data breaches and cybersecurity challenges. The survey revealed that a third of organizations have admitted to covering up data breaches, while 42% of IT leaders were instructed to maintain breach confidentiality. This trend of hiding data breaches is alarming as it puts customers' personal information at risk and undermines their trust in the organization.

The survey also highlighted the top cybersecurity concerns for businesses globally, with the most significant challenge being phishing attacks, followed by ransomware and zero-day exploits. These attacks are increasingly sophisticated and can cause significant financial and reputational damage to organizations.

According to Bogdan Botezatu, director of threat research and reporting at Bitdefender, "There is a significant gap between businesses' perceptions of their cybersecurity preparedness and the reality of their protection measures." The survey shows that while organizations are aware of the risks and the importance of cybersecurity, many are not taking sufficient measures to protect their systems and data.

It is essential for organizations to be transparent about data breaches and take necessary precautions to prevent them. They need to prioritize cybersecurity measures and invest in the latest technologies to protect their data from threats. As Botezatu emphasized, "By underestimating their exposure, businesses are not only putting themselves at risk but also their customers."

According to the poll, firms must act quickly to prevent cybersecurity problems and data breaches. In addition to making ensuring companies have sufficient security measures in place, they must be open about any security-related events. Only by implementing these measures can businesses keep the confidence of their customers and safeguard their data from online threats.

Christmas Eve Hack Targets Arnold Clark

Hackers launched a notorious Christmas Eve cyberattack against Arnold Clark, a car dealership. The network issue that has affected computer and telephone services has caused customers who had appointments this week for maintenance and repairs to be rescheduled.

Uncertainty surrounds the issue's timing as the vehicle manufacturer operates two dealerships in the town both on Annan Road. This incident is just one indication of how susceptible businesses can be to online crime, especially over the holidays when many firms are less watchful of security precautions than they typically would be.

The company's IT security staff confirmed that, as of right now, there is no proof of client data being compromised when the system fault first surfaced on Christmas Eve.

On Wednesday, an official told the newspaper: "Over the Christmas holiday, we experienced a network issue that had an impact on both our computer and phone systems. Through their investigations so far, our IT security team has verified that there is no proof that any customer data has been hacked. We want to take this chance to express our gratitude to our clients for their understanding and our regret for any trouble this may have caused."

The attack's origin is still an enigma, but it might have been brought on by various factors. It is possible that an employee unintentionally clicked a harmful link or attachment in an email, allowing hackers to access the company's networks. Another theory is that the attack occurred via a zero-day exploit, which refers to a software flaw previously unknown and used by hackers to enter networks before it is too late.

If sufficient cybersecurity precautions are not taken, cyberattacks such as the one Arnold Clark experienced can occur at any moment and cause significant harm. Businesses must ensure they have sufficient safeguards in place, including multi-factor authentication and frequent system updates, as well as educate their personnel on fundamental cybersecurity concepts like avoiding clicking links from unknown sources and maintaining passwords safe and secure.

Google Patched the Eighth Actively Abused Chrome Zero Day This Year

 

The eighth zero-day vulnerability affecting the Chrome browser on Windows, Mac, Linux, and Android platforms has been acknowledged by Google. You can force-update your browser right away, but an urgent remedy for this one problem is currently being rolled out. There will shortly be upgrades for other Chromium-powered browser clients as well. 

When a Google Chrome update fixed a single security issue, it used to happen very infrequently and only when a vulnerability was actively being utilized by attackers in the wild before a fix was ready. Updates covering a total of eight of these zero days were released in 2022. 

The most recent is CVE-2022-4135, a high-severity heap buffer overflow flaw in the Chromium GPU. The National Institute of Standards and Technology (NIST) national vulnerability database entry states that the zero-day, which was disclosed by Clement Lecigne of Google's own Threat Analysis Group, could allow an attacker to circumvent the security sandbox (using a malicious HTML website). 

The zero-day has not received any additional information from Google. This is not uncommon with such a vulnerability so as to enable a majority of users to install the update and gain protection before other attackers try their hands. All Google has said is that it is "aware that an exploit for CVE-2022-4135 exists in the wild." 

Update Your Google Chrome Browser Immediately 

Google has already started rolling out security updates will continue in the coming days. However, users are recommended to force the update process, given that malicious hackers are known to have exploited code already. This is particularly important for those users who maintain large numbers of open tabs and rarely restart the browser, as the update is only effective following a restart. 

Head for settings in the chrome browser and scan if you have the latest version and if not, then a download and installation will start automatically. The security update takes Chrome to version 107.0.5304.121 or.122 for Windows, version 107.0.5304.121 for Mac and Linux, and version 107.0.5304.141 for Android.

Miami Hacking Contest Vulnerabilities and Exploits Zero Day exploit

ICS Exploits Earn Hackers $400,000 at Pwn2Own Miami Hacking Contest

 

Pwn2Own Miami 2022 has come to an end, and Zero Day Initiative says the competitors earned $400,000 for 26 zero-day exploits (and multiple vulnerability collisions) targeting ICS and SCADA products exhibited during the contest held last week. 

The contest, organized by Trend Micro’s Zero Day Initiative (ZDI), saw 11 participants targeting multiple production categories: Control Server, OPC Unified Architecture (OPC UA) Server, Data Gateway, and Human Machine Interface (HMI). 

"Thanks again to all of the competitors who participated. We couldn’t have a contest without them," Trend Micro's Zero Day Initiative (ZDI) said today. “Thanks also to the participating vendors for their cooperation and for providing fixes for the bugs disclosed throughout the contest.”

After the safety vulnerabilities abused throughout Pwn2Own are reported, distributors are given 120 days to launch patches till ZDI publicly discloses them. 

The highest payout went to Computest Sector 7 researchers Daan Keuper (@daankeuper) and Thijs Alkemade (@xnyhps). During day one, they earned $20,000 after executing code on the Inductive Automation Ignition SCADA control server solution using a missing authentication vulnerability. 

The same day they used an uncontrolled search path bug to secure remote code execution (RCE) in AVEVA Edge HMI/SCADA software and were awarded $20,000 for their efforts. The next day, Computest Sector 7 exploited an infinite loop condition to trigger a DoS state against the Unified Automation C++ Demo Server and earned $5,000.

Last but not least, on day two of Pwn2Own Miami 2022, the Computest Sector 7 team earned $40,000 for successfully bypassing the trusted application check on the OPC UA .NET standard. This was the maximum amount that Pwn2Own participants could earn for a single exploit, and Computest’s attempt involved what ZDI described as one of the most interesting bugs ever seen at Pwn2Own. In fact, the Computest team earned the most points and a total of $90,000. 

This year's Pwn2Own Miami took place at the S4 conference in Miami South Beach in person and also allowed remote participation. In 2020, in the first edition of Pwn2Own on ICS, participants won a total of $ 280,000. This event did not take place in 2021 due to the COVID-19 pandemic.

Adobe Adobe Experience Manager CMS Vulnerabilities and Exploits Zero Day exploit

Zero-day Exploit Detected in Adobe Experience Manager

 

A zero-day vulnerability in a prominent content management solution used by high-profile firms such as Deloitte, Dell, and Microsoft has been found. 

The flaw in Adobe Experience Manager (AEM) was detected by two members of Detectify's ethical hacking community.

Adobe Experience Manager (AEM) is a popular content management system for developing digital customer experiences like websites, mobile apps, and forms. AEM has become the primary Content Management System (CMS) for many high-profile businesses due to its comprehensiveness and ease of use. 

The flaw allows hackers to bypass authentication and obtain access to CRX Package Manager, making applications vulnerable to Remote code execution attacks. It affects CR package endpoints and can be fixed by denying public access to the CRX consoles. 

Detectify spokesperson stated, "With access to the CRX Package Manager, an attacker could upload a malicious package in Adobe Experience Manager to leverage it to an RCE and gain full control of the application." 

Ai Ho and Bao Bui, members of Detectify Crowdsource, initially detected the vulnerability in an instance of AEM used by Sony Interactive Entertainment's PlayStation subsidiary in December 2020. Three months later, the AEM CRX bypass was discovered within various Mastercard subdomains. The issues were reported to Sony and Mastercard at the time. 

Mastercard, LinkedIn, PlayStation, and McAfee were among the prominent companies affected by the flaw, according to the members of Detectify. 

A Detectify spokesperson explained: "The CRX Package Manager is accessed by bypassing authentication in Dispatcher, Adobe Experience Manager’s caching and/or load balancing tool. Dispatcher checks user’s access permissions for a page before delivering the cached page and is an essential part of most – if not all – AEM installations. It can be bypassed by adding a lot of special characters in combination in the request." 

Bao Bui, a security researcher and former CTF player of the Meepwn CTF Team, began hunting bug bounties around a year ago. Ai Ho, a security engineer, and developer, has been involved in the bug bounty industry for two years, developing and releasing his own bug-catching tools on GitHub. 

Adobe was notified of the zero-day problem and quickly issued a patch. 

On Detectify's platform, the AEM CRX Bypass zero-day was then implemented as a security test module. "Since it went live in May 2021, around 30 instances of the AEM CRX Bypass vulnerability have been in customers’ web applications," added a Detectify spokesperson. 

So far, Detectify's scans for over 80 specific AEM vulnerabilities have produced over 160,000 hits.
