REDTIGER MALWARE STEALS DATA, DISCORD TOKENS, AND EVEN WEBCAM IMAGES

RedTiger, an open-source Python-based infostealer repurposed by cybercriminals, targets Discord gamers (especially French-speaking users) to steal authentication tokens, payment information, browser credentials, cryptocurrency wallets, and webcam images while modifying Discord to maintain persistent access even after password changes. The malware evades detection by shutting down when it detects security tools, employs "mass file and process spamming" (creating 100 random files and launching 400 programs to hinder forensic analysis), and exfiltrates stolen data via GoFile with Discord webhook notifications to attackers. Security professionals should implement multi-factor authentication on Discord accounts, avoid downloading software from unverified sources, and recognize that legitimate security testing tools are increasingly weaponized for credential theft campaigns.

AN ALZHEIMER'S PILL APPEARS TO PROTECT SOME IN A HIGH-RISK POPULATION

An experimental drug called valiltramiprosate (ALZ-801) slowed cognitive decline by 52% in people with mild cognitive impairment in a study of more than 300 people aged 50 or older who were genetically predisposed to Alzheimer's disease. Participants who received the drug experienced about 18% less atrophy in the hippocampus compared to those who received a placebo. ALZ-801 is a twice-daily pill that can be taken at home. It works by preventing amyloid proteins from clumping and forming plaques.
