A sprawling online company based in Georgia that has made tens of millions of dollars purporting to sell access to jobs at the United States Postal Service (USPS) has exposed its internal IT operations and database of nearly 900,000 customers. The leaked records indicate the network’s chief technology officer in Pakistan has been hacked for the past year, and that the entire operation was created by the principals of a Tennessee-based telemarketing firm that has promoted USPS employment websites since 2016. The website FederalJobsCenter promises to get you a job at the USPS in 30 days or your money back. KrebsOnSecurity was recently contacted by a security researcher who said he found a huge tranche of full credit card records exposed online, and that at first glance the domain names…

Companies welcome input from industry participants and advocacy groups on a draft specification to alert users in the event of suspected unwanted tracking Location-tracking devices help users find personal items like their keys, purse, luggage, and more through crowdsourced finding networks. However, they can also be misused for unwanted tracking of individuals. Today Google and Apple jointly submitted a proposed industry specification to help combat the misuse of Bluetooth location-tracking devices for unwanted tracking. The first-of-its-kind specification will allow Bluetooth location-tracking devices to be compatible with unauthorized tracking detection and alerts across Android and iOS platforms. Samsung, Tile, Chipolo, eufy Security, and Pebblebee have expressed support for the draft specification, which offers best practices and instructions for manufacturers, should they choose to build these capabilities into their products. “Bluetooth trackers…

Posted by Rae Wang, Director of Product Management (Android Security and Privacy Team) Unlike other mobile OSes, Android is built with a transparent, open-source architecture. We firmly believe that our users and the mobile ecosystem at-large should be able to verify Android’s security and safety and not just take our word for it. We’ve demonstrated our deep belief in security transparency by investing in features that enable users to confirm that what they expect is happening on their device is actually happening. The Assurance of Android Protected Confirmation One of those features is Android Protected Confirmation, an API that enables developers to utilize Android hardware to provide users even more assurance that a critical action has been executed securely. Using a hardware-protected user interface, Android Protected Confirmation can help developers…

A shocking number of organizations — including banks and healthcare providers — are leaking private and sensitive information from their public Salesforce Community websites, KrebsOnSecurity has learned. The data exposures all stem from a misconfiguration in Salesforce Community that allows an unauthenticated user to access records that should only be available after logging in. A researcher found DC Health had five Salesforce Community sites exposing data. Salesforce Community is a widely-used cloud-based software product that makes it easy for organizations to quickly create websites. Customers can access a Salesforce Community website in two ways: Authenticated access (requiring login), and guest user access (no login required). The guest access feature allows unauthenticated users to view specific content and resources without needing to log in. However, sometimes Salesforce administrators mistakenly grant guest…

Posted by Anu Yamunan and Khawaja Shams (Android Security and Privacy Team), and Mohet Saxena (Compute Trust and Safety) Keeping Google Play safe for users and developers remains a top priority for Google. Google Play Protect continues to scan billions of installed apps each day across billions of Android devices to keep users safe from threats like malware and unwanted software. In 2022, we prevented 1.43 million policy-violating apps from being published on Google Play in part due to new and improved security features and policy enhancements — in combination with our continuous investments in machine learning systems and app review processes. We also continued to combat malicious developers and fraud rings, banning 173K bad accounts, and preventing over $2 billion in fraudulent and abusive transactions. We’ve raised the bar…

Bob Callaway, Staff Security Engineer, Google Open Source Security team Last week the Open Source Security Foundation (OpenSSF) announced the release of SLSA v1.0, a framework that helps secure the software supply chain. Ten years of using an internal version of SLSA at Google has shown that it’s crucial to warding off tampering and keeping software secure. It’s especially gratifying to see SLSA reaching v1.0 as an open source project—contributors have come together to produce solutions that will benefit everyone. SLSA for safer supply chains Developers and organizations that adopt SLSA will be protecting themselves against a variety of supply chain attacks, which have continued rising since Google first donated SLSA to OpenSSF in 2021. In that time, the industry has also seen a U.S. Executive Order on Cybersecurity and…

We learned some remarkable new details this week about the recent supply-chain attack on VoIP software provider 3CX. The lengthy, complex intrusion has all the makings of a cyberpunk spy novel: North Korean hackers using legions of fake executive accounts on LinkedIn to lure people into opening malware disguised as a job offer; malware targeting Mac and Linux users working at defense and cryptocurrency firms; and software supply-chain attacks nested within earlier supply chain attacks. Researchers at ESET say this job offer from a phony HSBC recruiter on LinkedIn was North Korean malware masquerading as a PDF file. In late March 2023, 3CX disclosed that its desktop applications for both Windows and macOS were compromised with malicious code that gave attackers the ability to download and run code on all machines…

For the past seven years, a malware-based proxy service known as “Faceless” has sold anonymity to countless cybercriminals. For less than a dollar per day, Faceless customers can route their malicious traffic through tens of thousands of compromised systems advertised on the service. In this post we’ll examine clues left behind over the past decade by the proprietor of Faceless, including some that may help put a face to the name. The proxy lookup page inside the malware-based anonymity service Faceless. Image: spur.us. Riley Kilmer is co-founder of Spur.us, a company that tracks thousands of VPN and proxy networks, and helps customers identify traffic coming through these anonymity services. Kilmer said Faceless has emerged as one of the underground’s most reliable malware-based proxy services, mainly because its proxy network has…

Posted by David Dworken, Information Security Engineer, Google Security Team Many web applications need to display user-controlled content. This can be as simple as serving user-uploaded images (e.g. profile photos), or as complex as rendering user-controlled HTML (e.g. a web development tutorial). This has always been difficult to do securely, so we’ve worked to find easy, but secure solutions that can be applied to most types of web applications. Classical Solutions for Isolating Untrusted Content The classic solution for securely serving user-controlled content is to use what are known as “sandbox domains”. The basic idea is that if your application's main domain is example.com, you could serve all untrusted content on exampleusercontent.com. Since these two domains are cross-site, any malicious content on exampleusercontent.com can’t impact example.com. This approach can be…
