Technical details for a critical Cisco IOS XE Wireless LAN Controller (WLC) vulnerability, tracked as CVE-2025-20188, have now been publicly disclosed. The flaw, which allows arbitrary file upload, poses a maximum severity risk to affected systems. Originally announced in early May 2025, this vulnerability impacts Cisco’s IOS XE-based WLC devices, widely used to manage enterprise Wi-Fi networks. By exploiting the flaw, attackers can upload malicious files to the controller, potentially leading to unauthorized code execution, network compromise, or disruption of wireless services. Cisco had issued an advisory urging users to apply available patches promptly. However, the recent public release of…

Cartier has become the latest high-end fashion house to fall victim to a data breach, joining a growing list of fashion brands grappling with digital threats. In breach notification letters sent to affected individuals (and now circulating on social media) Cartier confirmed that threat actors managed to breach its systems and access customer data. “We are writing to inform you that an unauthorized party gained temporary access to our system and obtained limited client information,” the company stated. While the incident was reportedly contained swiftly, the breach still exposed personal information including customer names, email addresses, and their countries of…

The cybercrime landscape has entered a new era, one where a $2 stolen password can trigger a multimillion-dollar breach. According to ReliaQuest’s latest report, The Infostealer Pipeline: How Russian Market Fuels Credential-Based Attacks, the underground economy of stolen credentials is thriving, industrialized, and alarmingly easy to access. For organizations today, this isn’t just a threat—it’s a crisis of compromise. A $2 Price Tag on Your Network? At the heart of this ecosystem sits Russian Market, a dark web Automated Vending Cart (AVC) where threat actors can buy infostealer logs for less than the cost of a coffee. These logs contain…

Cybersecurity researchers from Cybernews have uncovered two misconfigured Azure Blob Storage containers containing more than 1.6 million files, primarily shipping email confirmations. The vast majority of the leaked data appears to belong to American customers, though some affected individuals are located in Canada and Australia. The emails were linked to purchases from Etsy, TikTok shops, Poshmark, and a vendor called Embroly. Most exposed files were HTML versions of shipping confirmations, containing sensitive customer information such as full names, home addresses, email addresses, and shipping order details. While it’s unclear who owns the storage buckets, metadata suggests the orders originated from…

On 21 May, a major international law enforcement coalition, including Europol, the FBI, and Microsoft, announced a coordinated operation targeting the notorious Lumma infostealer, a malware-as-a-service platform responsible for widespread credential theft. The operation, which began on 15 May, confiscated a whopping 2,500 domains associated with Lumma and wiped its main server and backups through a vulnerability in Integrated Dell Remote Access Controller (iDRAC). Lumma, one of the most prolific infostealers, has been leveraged by both common cybercrooks and elite threat groups such as Scattered Spider, Angry Likho, and CoralRaider. The takedown’s immediate impact was evident as Lumma customers flooded…

Recent data breaches at luxury brands under LVMH, the world’s largest luxury conglomerate, have raised concerns over the group’s data security practices, particularly among consumers. The most recent incident involved Tiffany & Company, which revealed on 9 May that personal data from its Korea-based customers, including names, addresses, phone numbers, email addresses, and sales information, had been compromised. The breach happened on 8 April but wasn’t identified until a month later. The company has said no financial information, such as payment card details, was involved, but its response was limited to notifying affected individuals via email. Similar concerns have been…

A newly uncovered flaw in Microsoft’s OneDrive File Picker could be putting millions of users at risk of unintended data exposure, says new research from cybersecurity firm Oasis Security.   The issue allows websites to access an entire user’s OneDrive, rather than just the specific files selected for upload, due to a combination of excessive permissions and vague consent prompts. The flaw affects hundreds of popular applications that integrate with OneDrive File Picker, including widely used platforms like ChatGPT, Slack, Trello, and ClickUp. As a result, millions of users may have inadvertently granted these services full access to their cloud storage,…

A newly identified threat actor, Void Blizzard, is emerging as a major player in Russian-linked cyberespionage, according to a detailed report by Microsoft Threat Intelligence. Active since at least April 2024, Void Blizzard is now on the radar of global security agencies for its highly targeted campaigns against government, defense, healthcare, and media organizations, primarily in NATO member states and Ukraine. Backed by evidence and collaboration from the Netherlands’ General and Defence Intelligence and Security Services (AIVD and MIVD), as well as the FBI, the report describes Void Blizzard (also known as LAUNDRY BEAR) as a determined and opportunistic actor,…

A recent investigation by ReversingLabs (RL) has uncovered a new malicious attack method targeting machine learning (ML) models distributed via the Python Package Index (PyPI). This expands on earlier threats that abused the Pickle file format to distribute malware through ML models hosted on platforms like Hugging Face. Threat actors uploaded three malicious PyPI packages—aliyun-ai-labs-snippets-sdk, ai-labs-snippets-sdk, and aliyun-ai-labs-sdk—posing as Python SDKs for interacting with Alibaba AI Labs services. In reality, these packages had no legitimate functionality and were designed solely to exfiltrate reconnaissance information from infected systems. Once installed, the packages delivered an infostealer payload hidden inside a PyTorch model,…

Cellcom, a regional telecom provider that serves Michigan and Wisconsin has confirmed that a cyberattack was the cause of text and voice service outages that began last week. Calls between Cellcom customers and some SMS text services have since been restored, and the company confirmed that the incident was concentrated on a network where customer data is not held. As of yesterday, Cellcom could not say when services will be fully restored. The company’s CEO Brighid Riordan said in a brief video statement, that the company has been dealing with a cyber incident but “simply don’t have a lot of…
