GhostPoster attacks hide malicious JavaScript in Firefox addon logos

A new campaign dubbed ‘GhostPoster’ is hiding JavaScript code in the image logo of malicious Firefox extensions with more than 50,000 downloads, to monitor browser activity and plant a backdoor.

The malicious code grants operators persistent high-privilege access to the browser, enabling them to hijack affiliate links, inject tracking code, and commit click and ad fraud.

The hidden script is acting as a loader that fetches the main payload from a remote server. To make the process more difficult to detect, the payload is intentionally retrieved only once in ten attempts.

A Planet 900 Light-Years Away Has Weather So Extreme “It Feels Like Science Fiction”. It’s 70,000 km/h Winds Carry Vaporized Iron and Even Titanium

Scientists have for the first time mapped the 3D structure of an exoplanet’s atmosphere, uncovering violent winds and bizarre weather patterns.

US develops method to spot illegal nuclear material origins in 30 mins

A simple instrument like mass spectrometer can revolutionize how unknown samples are investigated in the future.

A new method developed by researchers at the Los Alamos National Laboratory (LANL) can spot the origins of illegal nuclear material in just 30 minutes. Requiring only a relatively simple instrument, such as a mass spectrometer, the method can help identify the source of any nuclear material outside regulatory control.

According to the International Atomic Energy Agency (IAEA), theft or improper disposal can result in nuclear and radiological material falling out of regulatory control. In 2,024,124 such incidents were reported to the IAEA, of which at least three were linked to “trafficking or malicious use”

Earlier this year, a leader of a crime syndicate pleaded guilty to trafficking nuclear material in a New York court. The accused had discussed sale of yellowcake uranium with an undercover agent.

Intravascular immune surveillance against viremia requires spatiotemporal coordination between Kupffer cells and ILC1s

Zhang et al. reveal that hepatic ILC1s rapidly transition from intravascular patrolling to motility arrest upon encountering infected Kupffer cells (KCs) during viremia. This behavioral switch, driven by cell intrinsic type I IFN signaling and coupled to ILC1 activation, fortifies the antiviral function of KCs to restrict systemic viral dissemination.

Tiny particles ‘surf’ microcosmic waves to save energy in chaotic environments

Conditions can get rough in the micro- and nanoworld. For example, to ensure that nutrients can still be optimally transported within cells, the minuscule transporters involved need to respond to the fluctuating environment. Physicists at Heinrich Heine University Düsseldorf (HHU) and Tel Aviv University in Israel have used model calculations to examine how this can succeed. They have now published their results—which could also be relevant for future microscopic machines—in the journal Nature Communications.
