One of the world’s largest grocery retail groups has confirmed a major cyber incident that compromised sensitive information belonging to more than 2.2 million individuals across its U.S. operations.
The company, known for running supermarket chains like Food Lion, Giant Food, and Stop & Shop, revealed that a ransomware attack last November led to unauthorized access to internal systems. This breach primarily exposed employment-related data of current and former workers, according to a recent report filed with the Maine Attorney General’s office.
What Information Was Exposed?
While not everyone affected had the same type of data compromised, the company stated that hackers may have accessed a combination of the following:
• Full names and contact details
• Birth dates
• Government-issued ID numbers
• Bank account details
• Health and workers’ compensation records
• Job-related documents
The breach does not appear to involve customer information, according to the company’s internal review. In Maine alone, over 95,000 individuals were impacted, triggering formal notification procedures as required by law.
Company’s Response and Next Steps
Following the discovery of the breach on November 6, 2024, Ahold Delhaize immediately launched an investigation and worked to contain the attack. Temporary service disruptions were reported, including issues with pharmacies and delivery services.
To assist those affected, the company is offering two years of free credit and identity monitoring through a third-party provider. It has also engaged external cybersecurity experts to further review and enhance its systems.
Ransomware Group Possibly Involved
Although Ahold Delhaize has not officially identified the group behind the attack, a ransomware operation known as INC Ransom reportedly claimed responsibility earlier this year. Files believed to be taken from the company were published on the group’s leak site in April.
Cybersecurity professionals say the exposed information could be used for identity theft and financial fraud. Experts have advised affected individuals to monitor their credit reports and, where possible, lock their credit files as a precautionary measure.
A Growing Concern for the Sector
Cyberattacks on retail and food service companies are becoming more frequent and severe. According to researchers, this incident stands out due to the unusually high number of records affected. The average breach in this sector usually involves far fewer data points.
Security specialists say such events highlight the urgent need for stronger protection strategies, including multi-factor authentication, network segmentation, and stealth technologies that reduce exposure to cyber threats.
Ahold Delhaize at a Glance
Headquartered in the Netherlands and Belgium, Ahold Delhaize operates more than 9,400 stores worldwide and serves roughly 60 million customers each week. In 2024, the company recorded over $100 billion in global sales.
As the investigation continues, the company has pledged to strengthen its data safeguards and remain vigilant against future threats.
A major online platform for collectible items, Collectibles.com, has accidentally exposed the private information of nearly a million users. This security flaw could put many people at risk of identity theft, fraud, and online scams, according to cybersecurity experts.
How the Data Was Leaked
Cybersecurity researchers from Cybernews discovered that the website had an unprotected database, meaning anyone could access it without a password. This database contained 300GB of data and over 870,000 records, each linked to a different user. The leaked information included full names, email addresses, profile pictures, account details, records of collectible card sales, and other transaction history.
Experts warn that such leaks can be dangerous because cybercriminals might use this data for fraudulent activities, such as identity theft or phishing scams. Phishing is when scammers send fake emails or messages pretending to be from a trusted company to trick users into revealing passwords or financial information.
What Is Collectibles.com?
Previously known as Cardbase, Collectibles.com is an online marketplace where users can buy, sell, and track trading cards, comics, and memorabilia. In 2024, the company announced it had around 300,000 users. However, this data leak suggests the number of affected users might be much higher.
Company’s Response and Security Concerns
Cybernews contacted Collectibles.com to inform them about the security issue. However, aside from an automated response, the company did not take immediate action. It took ten days for the exposed database to be secured, but it remains unclear how long the data was accessible before it was discovered.
There is also uncertainty about whether hackers accessed the information before Cybernews reported it. If cybercriminals obtained this data, they could already be using it for scams or fraud.
Why Do These Leaks Happen?
One of the main reasons for data leaks is unsecured cloud databases. Many companies store customer information online but do not always follow proper security practices. Some businesses assume that cloud providers are fully responsible for security, but in reality, companies must also take steps to protect their data.
Cybercriminals and researchers alike use tools to search the internet for unprotected databases. Once found, these databases can be exploited in different ways, from selling private information to launching scams.
How Users Can Protect Themselves
If you have an account on Collectibles.com, consider taking the following steps:
1. Change your password immediately to ensure your account remains secure.
2. Enable two-factor authentication (2FA) to add an extra layer of protection.
3. Be cautious of phishing emails that may try to trick you into revealing personal details.
4. Monitor your accounts for suspicious activity and report anything unusual.
Cybersecurity experts emphasize that companies must take data security seriously to prevent such leaks. At the same time, users should remain cautious and take steps to protect their personal information online.
A significant data exposure incident involving the Chicago-based financial technology firm Willow has left the personal details of more than 240,000 customers vulnerable. Willow, which offers a service to pay customer bills upfront and allows repayment in installments, reportedly left a large volume of sensitive data accessible online without password protection. The discovery was made by cybersecurity researcher Jeremiah Fowler, who uncovered an unsecured database containing approximately 241,970 files.
The exposed data included customer names, email addresses, phone numbers, transaction details, and partial banking information. Alarmingly, receipts uploaded to the database revealed additional sensitive details, such as partial credit card numbers and home addresses. Fowler also found a T-Mobile bill containing call and text message records, underscoring the severity of the breach. One particularly concerning file contained data on 56,864 individuals categorized as prospects, active customers, or former customers barred from using Willow’s services.
The scale of the exposure raises significant concerns about the risk of identity theft and financial fraud. While there is no evidence yet that the leaked data has been exploited, the breach highlights the potential for phishing scams and social engineering attacks. Fraudsters could use the exposed information to craft convincing schemes, such as fraudulent billing requests or identity verification scams, targeting affected individuals.
Fowler immediately attempted to notify Willow of the breach, but his outreach went unanswered. Shortly thereafter, the database was secured and removed from public access. However, it remains unclear whether the database was managed directly by Willow or a third-party contractor. The duration of the exposure also remains unknown, raising concerns about whether unauthorized parties may have accessed the data before it was secured.
Experts recommend that affected customers take proactive measures to protect themselves. These include closely monitoring financial accounts for unusual activity, changing passwords linked to Willow, and remaining vigilant against phishing attempts. Customers should be cautious of unsolicited communications requesting personal or financial information, as scammers may leverage the exposed data to appear legitimate.
Willow has yet to publicly address the breach or outline measures to prevent future incidents. This lack of transparency underscores the importance of stringent data protection protocols. Cybersecurity experts stress that companies handling sensitive financial information must regularly audit their systems to identify and mitigate vulnerabilities.
Until Willow provides clarity, customers must rely on their own vigilance to safeguard against potential misuse of their information. This incident serves as a stark reminder of the growing need for robust data security practices in today’s digital landscape.
Earlier this year, a hacker successfully breached OpenAI's internal messaging systems, obtaining sensitive details about the company's AI technologies. The incident, initially kept under wraps by OpenAI, was not reported to authorities as it was not considered a threat to national security. The breach was revealed through sources cited by The New York Times, which highlighted that the hacker accessed discussions in an online forum used by OpenAI employees to discuss their latest technologies.
The breach was disclosed to OpenAI employees during an April 2023 meeting at their San Francisco office, and the board of directors was also informed. According to sources, the hacker did not penetrate the systems where OpenAI develops and stores its artificial intelligence. Consequently, OpenAI executives decided against making the breach public, as no customer or partner information was compromised.
Despite the decision to withhold the information from the public and authorities, the breach sparked concerns among some employees about the potential risks posed by foreign adversaries, particularly China, gaining access to AI technology that could threaten U.S. national security. The incident also brought to light internal disagreements over OpenAI's security measures and the broader implications of their AI technology.
In the aftermath of the breach, Leopold Aschenbrenner, a technical program manager at OpenAI, sent a memo to the company's board of directors. In his memo, Aschenbrenner criticised OpenAI's security measures, arguing that the company was not doing enough to protect its secrets from foreign adversaries. He emphasised the need for stronger security to prevent the theft of crucial AI technologies.
Aschenbrenner later claimed that he was dismissed from OpenAI in the spring for leaking information outside the company, which he argued was a politically motivated decision. He hinted at the breach during a recent podcast, but the specific details had not been previously reported.
In response to Aschenbrenner's allegations, OpenAI spokeswoman Liz Bourgeois acknowledged his contributions and concerns but refuted his claims regarding the company's security practices. Bourgeois stated that OpenAI addressed the incident and shared the details with the board before Aschenbrenner joined the company. She emphasised that Aschenbrenner's separation from the company was unrelated to the concerns he raised about security.
While the company deemed the incident not to be a national security threat, the internal debate it sparked highlights the ongoing challenges in safeguarding advanced technological developments from potential threats.
In today’s rapidly advancing digital world, how organisations store their data is crucial to their cybersecurity strategies. Whether protecting sensitive customer information, securing intellectual property, or ensuring smooth business operations, effective data storage methods can prominently impact an organisation's defence against cyber threats.
Modern businesses are experiencing a massive increase in data generation. This surge is driven by technological innovation, growing customer interactions, and expanding business operations. As data continues to grow at an exponential rate, organisations must find ways to fully utilise this data while also ensuring its security and availability.
Cyberattacks are becoming more frequent and sophisticated, making data protection a top priority for businesses. Ransomware attacks, in particular, are a major concern. These attacks involve cybercriminals encrypting an organisation’s data and demanding a ransom for its release. According to the Verizon 2023 Data Breach Investigations report, ransomware is involved in over 62% of incidents linked to organised crime and 59% of financially motivated incidents. The consequences of such attacks are severe, with businesses taking an average of 9.9 days to return to normal operations after a ransomware incident. Additionally, 1 in 31 companies worldwide faces weekly ransomware attacks, underscoring the urgent need for robust data protection measures.
Immutable data storage has become a key strategy in bolstering cybersecurity defences. Unlike traditional storage methods, which allow data to be modified or deleted, immutable storage ensures that once data is written, it cannot be altered or erased. This feature is crucial for maintaining data integrity and protecting critical information from tampering and unauthorised changes.
By adopting immutable storage solutions, organisations can significantly reduce the risks associated with cyberattacks, particularly ransomware. Even if attackers manage to penetrate the network, the immutable data remains unchanged and intact, rendering ransom demands ineffective. This approach not only protects sensitive information but also helps maintain business continuity during and after an attack.
As businesses continue to face the growing threat of cybercrime, adopting advanced data storage solutions like immutable storage is essential. By ensuring that data cannot be altered or deleted, organisations can better protect themselves from the devastating impacts of cyberattacks, safeguard critical information, and maintain operations without interruption. In an age where data is both a valuable asset and a prime target, robust storage strategies are indispensable to a comprehensive cybersecurity strategy.
A new attack, dubbed TunnelVision, has materialised as a threat to the security of virtual private network (VPN) applications, potentially compromising their ability to protect user data. Researchers have detected vulnerabilities affecting nearly all VPN apps, which could allow attackers to intercept, manipulate, or divert traffic outside of the encrypted tunnel, undermining the fundamental purpose of VPNs.
How TunnelVision Works
TunnelVision exploits a flaw in the Dynamic Host Configuration Protocol (DHCP) server, the system responsible for assigning IP addresses on a network. By manipulating a specific setting called option 121, attackers can divert VPN traffic through the DHCP server, bypassing the encrypted tunnel meant to secure the data. This manipulation allows attackers to intercept, read, drop, or modify the traffic, compromising the user's privacy and the integrity of the VPN connection.
Implications for VPN Users
The consequences of TunnelVision are severe. Despite users trusting that their data is securely transmitted through the VPN, the reality is that some or all of the traffic may be routed outside of the protected connection. This means that sensitive information, such as passwords, financial details, or personal communications, could be exposed to interception or manipulation by unauthorized parties.
The vulnerability affects a wide range of operating systems and devices, with the exception of Android, which does not implement option 121 in its DHCP server. For other operating systems, including Linux, there are no complete fixes available. Even with mitigations in place, such as minimising the effects on Linux, TunnelVision can still exploit side channels to compromise security.
While there is no foolproof solution to the TunnelVision attack, certain measures can reduce the risk. Running the VPN inside a virtual machine or connecting through a cellular device's Wi-Fi network can enhance security by isolating the VPN connection from potential attacks. However, these solutions may not be accessible or practical for all users, highlighting the need for further research and development in VPN security.
TunnelVision represents a harrowing threat to the integrity of VPNs, undermining their ability to protect user data from interception and manipulation. With the potential for widespread exploitation, it is essential for VPN providers and users to be aware of the risks and take appropriate measures to steer clear of potential attacks.
Cybersecurity incidents have become increasingly common in the mortgage industry, with multiple lenders and servicers experiencing data breaches that compromised sensitive customer information. Carrington Mortgage Services is the latest player to be impacted, as a ransomware attack at its vendor Alvaria compromised the information of its customers, including partial Social Security numbers.
In this blog post, we'll take a closer look at the details of this breach, as well as other recent cybersecurity incidents in the mortgage industry.
Last week, Carrington Mortgage Services announced that a technology company it uses, Alvaria, experienced a ransomware attack in March. As a result, the personal information of some of Carrington's customers, including partial Social Security numbers, was compromised.
Although neither Carrington nor Alvaria disclosed the total number of affected clients, a letter to state attorneys general indicated that at least 4,167 residents of Massachusetts were impacted. This is the most recent hack of a mortgage player, following a series of incidents across the industry last year.
Alvaria responded to the attack by restoring its operations through backups and securing its networks. According to the Lowa letter, “the unauthorized actor obtained some data associated with the company maintained in the technical system log and temp files.” “While Alvaria performed its forensic investigation, the company completed its analysis of the affected data on April 4, 2023
According to Carrington Mortgage Services, compromised data due to the breach at Alvaria includes clients' names, mailing addresses, telephone numbers, loan numbers and balances, and the last four digits of their Social Security numbers.
However, when asked about Alvaria's reported data breach, Carrington's attorney declined to comment, while Alvaria's general counsel deferred to a company spokesperson. Alvaria did notify the FBI and took additional security measures following the breach, although the details of these measures were not disclosed.
In an effort to mitigate the effects of the breach, Carrington is offering customers 24 months of free credit monitoring and fraud consultation from Experian. In a letter to the Iowa Attorney General, Carrington defended its information security diligence and stated that it had received positive reviews from state and federal regulators, rating agencies, and banking counterparts.
The letter signed by the attorney for Carrington said: “Nevertheless, in light of this event, the company has begun an additional assessment of Alvaria's technical security measures to ensure that Alvaria has been providing and will continue to provide the security measures promised to the company and to help ensure this type of incident does not happen again.”
Carrington Mortgage Services has been actively involved in the mortgage servicing rights market and purchased $62.3 billion in 2020, making it one of the top 25 services in the country. In total, it holds $122.1 billion in MSRs from 682,000 borrowers. This incident is the second data breach at Alvaria within four months, with the previous attack being disclosed in February and impacting 4,695 customers.
The Hive Ransomware group was responsible for this attack, and in November, the group released corporate records on the dark web, though no customer data was included. It's unclear whether the November breach affected mortgage customer data. In 2021 alone, various mortgage lenders have disclosed cybersecurity incidents that impacted 191,000 customers.
These attacks have ranged in severity, from incidents affecting as few as 600 customers to a third-party breach that impacted 139,493 customers of Hatch Bank in California. Several class action complaints against impacted companies remain pending in federal courts, including those against servicers such as Key Bank, Lower, and Overby-Seawell Company.
