Google Gemini flaw hijacks email summaries for phishing

Google Gemini for Workspace can be exploited to generate email summaries that appear legitimate but include malicious instructions or warnings that direct users to phishing sites without using attachments or direct links.

Such an attack leverages indirect prompt injections that are hidden inside an email and obeyed by Gemini when generating the message summary.

Despite similar prompt attacks being reported since 2024 and safeguards being implemented to block misleading responses, the technique remains successful.

Interlock ransomware adopts FileFix method to deliver malware

Hackers have adopted the new technique called ‘FileFix’ in Interlock ransomware attacks to drop a remote access trojan (RAT) on targeted systems.

Interlock ransomware operations have increased over the past months as the threat actor started using the KongTuke web injector (aka ‘LandUpdate808’) to deliver payloads through compromised websites.

This shift in modus operandi was observed by researchers at The DFIR Report and Proofpoint since May. Back then, visitors of compromised sites were prompted to pass a fake CAPTCHA + verification, and then paste into a Run dialog content automatically saved to the clipboard, a tactic consistent with ClickFix attacks.

Gigabyte motherboards vulnerable to UEFI malware bypassing Secure Boot

Dozens of Gigabyte motherboard models run on UEFI firmware vulnerable to security issues that allow planting bootkit malware that is invisible to the operating system and can survive reinstalls.

The vulnerabilities could allow attackers with local or remote admin permissions to execute arbitrary code in System Management Mode (SMM), an environment isolated from the operating system (OS) and with more privileges on the machine.

Mechanisms running code below the OS have low-level hardware access and initiate at boot time. Because of this, malware in these environments can bypass traditional security defenses on the system.

Researchers grow 400+ brain cell types—a leap for Alzheimer’s and Parkinson’s research

Scientists at ETH Zurich have broken new ground by generating over 400 types of nerve cells from stem cells in the lab, far surpassing previous efforts that produced only a few dozen. By systematically experimenting with combinations of morphogens and gene regulators, the researchers replicated the vast diversity of neurons found in the human brain. This breakthrough holds major promise for studying neurological diseases like Alzheimer’s and Parkinson’s, creating more accurate models for drug testing, and eventually even enabling neuron replacement therapies.

“These Colossal Structures Defy Imagination”: Astronomers Confirm Quipu’s Staggering 1.3-Billion-Light-Year Width, Making It the Largest Known Entity in the Universe

IN A NUTSHELL 🌌 The Quipu superstructure, spanning over 1.3 billion light-years, is the largest known entity in the universe. 🔭 Astronomers utilize X-ray galaxy clusters to map and analyze these massive cosmic formations. 📊 The immense size of superstructures like Quipu can distort critical cosmological measurements, affecting our understanding of the universe’s expansion. ⏳

Mysterious New Structure Discovered Hiding Inside Human Cells

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our health has just been added to the anatomy books.

The membrane-bound organelle appears to play a huge role in helping cells sort, discard, and recycle their contents. It’s called a hemifusome, and a team of scientists says it could shed new light on disease.

“This is like discovering a new recycling center inside the cell,” said biophysicist Seham Ebrahim of the University of Virginia. “We think the hemifusome helps manage how cells package and process material, and when this goes wrong, it may contribute to diseases that affect many systems in the body.”

SRS Lessens Rate of Neurologic Death vs WBRT in SCLC and Brain Metastases

In all patients, the median overall survival (OS) was 10.2 months (95% CI, 8.5−12.2); there was a total of 20 neurologic deaths compared with 64 non-neurologic deaths. Between the 2 reviewers, agreement was 98% regarding neurologic death and non-neurologic death, with disagreement requiring a tie occurring in 2%.

The 1-year and 2-year neurologic death incidence was 11.0% (95% CI, 5.8%-18.1%) and 20.3% (95% CI, 12.7%-29.1%), respectively. The trial investigators noted that the historical incidence of neurologic death with WBRT was 17.5% at 1 year and 35.2% at 2 years. The 1-year and 2-year incidence of non-neurologic death was 48.0% (95% CI, 37.9%-57.4%) and 61.7% (95% CI, 50.8%-70.8%).

Via the Fine and Gray regression analysis, age, number of brain metastases, size of largest brain metastases, presence of neurologic symptoms, presence of distant extracranial metastases, and employment of neurological resection before enrollment were not associated with neurological death (P .05 in all cases).

New brain metastases were developed by 61.0% of patients, with a 1-year estimate of 59.0% (95% CI, 48.6%-68.0%); at least 1 course of salvage stereotactic radiation was received by 39.0% of patients, with a 1-year estimate of 37.0% (95% CI, 27.5%-46.5%); WBRT was received by 22.0%, with a 1-year estimate of 21.0% (95% CI, 13.6%-29.5%); and leptomeningeal disease was observed in 9.0%, with a 1-year estimate of 7.0% (95% CI, 3.1%-13.1%).

Overall, systemic disease progression occurred in 65.0% of patients, with a 1-year estimate of 58% (95% CI, 47.6%-67.0%).

Additionally, in aggregate, at least 1 local recurrence in a metastasis treated in the study was experienced by 13.0%, with a 1-year estimate of 15.0% (95% CI, 8.8%-22.7%); the respective per-patient rates of radiographic and symptomatic necrosis were 9.0% and 5.0% in total, with 1-year estimates of 6.0% (95% CI, 2.4%-11.9%) and 3.0% (95% CI, 0.8%-7.9%), respectively.

“Despite being the historical standard, whole brain radiation might not be necessary for all patients,” stated first study author Ayal Aizer, MD, MHS, director of Central Nervous System Radiation Oncology at Brigham and Women’s Hospital, and a founding member of the Mass General Brigham healthcare system, in a press release on the study.2 “Our findings demonstrate that targeted, brain-directed radiation may be a viable treatment for patients with limited brain metastases from SCLC and potentially spare them from the [adverse] effects of whole brain radiation.”
