Threema messenger says DDoS attacks disrupted its service for two days

Threema experienced significant disruptions due to large-scale DDoS attacks, rendering the service inaccessible for several hours on Tuesday and causing intermittent outages on Wednesday morning. The attacks targeted both Threema and its Swiss colocation partner, Nine, with service being unavailable from 7:30 p.m. to 11:30 p.m. CEST on Tuesday. By 12:23 p.m. on Wednesday, normal operations were restored. The security of Threema's systems and user data remained intact despite the service availability issues. The nature of the attacks made mitigation challenging, as attackers modified their methods rapidly. Threema's status page faced issues during the outage, and communication was conducted via email and social media. In response, Threema is implementing specialized upstream DDoS protection and plans to enhance its status page to provide monitoring for future disruptions.

Databricks acquires Electric to give every AI agent its own Postgres database

Databricks has acquired Electric, a startup known for its WASM-based Postgres project, PGlite, and the Electric sync engine. The Electric team will integrate with Neon, a serverless Postgres company acquired by Databricks for approximately billion last year. PGlite is a full Postgres database implemented in WebAssembly, capable of running in various environments and supporting dynamic extension loading, including pgvector. PGlite's weekly downloads increased from 1 million to 13 million over the past year. The Electric sync engine allows near real-time synchronization of a central Postgres database across platforms, similar to collaborative tools like Figma and Google Docs. Electric's founders have assured that all previously open-sourced components will remain accessible, while the hosted service, Electric Cloud, will be phased out. Databricks has noted that agents are now responsible for creating four times more databases than human users on Lakebase, with the average lifespan of a database compute instance being less than 10 seconds. The architecture of Lakebase separates storage from compute, facilitating cost-effective operations. PGlite originated from an experiment by Stas Kelvich, co-founder of Neon, who compiled Postgres to WASM, which Electric later developed into a production project.

Your favorite Android apps might be leaking your location

A report from the Electronic Frontier Foundation (EFF) highlights concerns about third-party software development kits (SDKs) in mobile applications collecting and sharing user location data with advertising companies, often without user consent. Many developers use these advertising SDKs for monetization, but their default settings allow for location data collection. This data is sent to advertising companies and location data brokers, which can misuse it in sensitive contexts. Users may unknowingly expose their location data when granting permissions to apps, as third-party SDKs can access this information without clear user awareness. The EFF identified several advertising SDKs, including InMobi, BidMachine, Verve’s HyBid, and Huawei’s Petal Ads, that collect and share location data by default. Developers are encouraged to review SDK settings to protect user privacy, and the EFF calls for regulatory scrutiny of data harvesting practices.

Developers: Beware of Ad Libraries that Betray Your Users’ Location

Advertising companies provide software development kits (SDKs) for mobile app monetization, which often automatically transmit users' location data to ad systems and location data brokers, raising privacy concerns. Many developers and users may be unaware of this data sharing. When developers allow SDKs to collect location data, it poses risks beyond targeted ads, including potential misuse by agencies like ICE and global surveillance. Location data brokers harvest precise movements of individuals, often without their consent, through mobile applications. Some apps directly collaborate with data brokers, while others leak data through advertising SDKs during real-time bidding (RTB) auctions. An incident in 2025 revealed that many apps unknowingly contributed to a location data broker's database. Developers must understand their SDKs' location-sharing practices to mitigate risks. Advertising SDKs can collect location data automatically once users grant permission, without specific permissions for the SDKs themselves. Precise location data can be collected when apps have location permissions, leading to potential privacy violations. Several SDKs have been identified as collecting location data by default, increasing the risk of unintentional data leaks. The Electronic Frontier Foundation (EFF) found that four advertising SDKs collect users' location data by default when location permissions are granted. InMobi encourages location sharing for higher revenue, while BidMachine updated its documentation after EFF's inquiry, confirming precise location data collection. Verve's SDK also collects location data by default but presents a cautious narrative in its Play Store guidance. Huawei's SDK recommends obtaining location permissions to enhance revenue, with default location sharing occurring if permissions are granted. Location data can be shared without users' knowledge or meaningful consent, complicating informed consent issues. The focus on four SDKs does not imply that others adequately protect location data, as many have faced criticism for similar practices. Studies indicate that SDKs often encourage increased data collection through design and documentation, leading to minimal control for developers over data transmission. The EFF's analysis highlights that advertising SDKs incentivize location data sharing through default settings and unclear documentation. Developers should assess third-party SDKs and disable unnecessary data collection. Regulators must hold developers accountable for unlawful data sharing, while legislators should enact laws to protect location privacy and address online behavioral advertising, which drives data tracking.

Tor launches Snowflake Android app to help users bypass censorship

The Tor Project has launched Snowflake Volunteer, an Android app that allows users to share their internet bandwidth to help others bypass online censorship. Snowflake functions as a Tor pluggable transport, disguising user traffic as video calls and routing it through temporary proxies managed by volunteers, making detection by censors more difficult. The app was developed by Bloco, a Portuguese studio, in collaboration with Tor’s anti-censorship team and is designed to be user-friendly while minimizing battery consumption. Users can configure the app to operate on unmetered networks and limit connections. Snowflake Volunteer is available on Google Play and F-Droid, with its source code also accessible for independent use. Volunteers are advised to consider their data limits and device impact before using the app.

DoubleVerify finds dozens of Android apps a month showing ads after calls

A recent analysis by DoubleVerify engineers has identified a trend in mobile advertising known as AfterCall ads, where applications display advertisements immediately after a phone call ends. This practice generates hundreds of millions of impressions monthly and raises concerns about user experience and brand integrity. AfterCall applications operate using three components: a misleading permission, a Broadcast Receiver to capture end-of-call events, and an Activity to display ads. The SYSTEMALERTWINDOW permission allows these apps to show content over others, often granted under false pretenses. They utilize Android's telephony system to trigger ads post-call and employ tactics to obscure their presence, such as removing themselves from the recent apps list and using innocuous icons. Detection is challenging due to the lack of shared codebases and the obfuscation techniques used. The scale of the issue is significant, with numerous AfterCall applications identified monthly, negatively impacting user experience and raising concerns for advertisers.
