CISA decides weekly vulnerability bulletin isn't necessary anymore
CISA will discontinue its weekly vulnerability bulletin on September 28, pushing users toward KEV, alerts, and CVE data under risk-based prioritization.
CISA announced its weekly vulnerability bulletin will stop on Monday, September 28, as part of a shift from static CVSS severity scores to a modern, risk-based approach detailed in a June Binding Operational Directive. The directive prioritizes federal remediation based on exposure, exploitation evidence, control granted by exploitation, and whether exploitation can be automated. CISA directs bulletin subscribers to rely instead on its Known Exploited Vulnerabilities catalog, cybersecurity alerts and advisories, and the CVE catalog, requiring users to enable those subscriptions in GovDelivery or Granicus to avoid missing critical notices.

Three Ukrainians to face charges for alleged hack of 610,000 Roblox accounts
Ukrainian prosecutors charged three men for stealing session tokens from over 610,000 Roblox accounts and selling them for an estimated $480,000.
Prosecutors in Ukraine's Lviv region said a 19-year-old organizer from Drohobych and two 22-year-old associates operated from May 2025 to April 2026, harvesting Roblox session tokens via infostealer malware disguised as game cheats and bonus software. They used software to validate stolen cookies and inventory virtual currency and rare items, then sold accounts via Russian platforms for as little as $0.80 each, advertising through Telegram channels and receiving crypto payments. All three are in custody facing charges of theft, money laundering, unauthorized computer interference, and illegal sale of restricted information, carrying up to 12 years in prison.

Russian data centers face new security requirements amid Ukraine's drone threats
A new Russian decree tightens critical-infrastructure security requirements, forcing data center operators to boost physical and digital defenses amid Ukrainian drone attacks.
A decree signed by President Putin in late August lets the Russian government temporarily take control of critical infrastructure, including data centers, if operators fail to protect facilities from drone attacks. Russia hosts 181 data centers, many concentrated around Moscow and St. Petersburg, areas increasingly exposed to Ukrainian long-range drone operations. Operators report higher capital expenditures for physical defenses and cybersecurity, costs likely passed to customers. Ukraine has also struck data centers in Kyiv, and Russia has expanded anti-drone measures such as netting and metal barriers.

A 52-year-old Ukrainian software developer went on trial at Zurich District Court over alleged involvement in ransomware attacks using LockerGoga, MegaCortex and Nefilim, with victims including Stadler Rail, Crealogix and Meier Tobler.

Brazil orders Discord to suspend livestreaming after teen suicide
Brazil's data protection authority orders Discord to disable its Go Live livestreaming feature nationwide until child-safety safeguards are demonstrated.
Brazil's National Data Protection Authority (ANPD) found robust evidence that Discord failed to protect children from harmful content and ordered the Go Live feature suspended until effective safeguards are shown, following the July death of a 13-year-old girl during a roughly 45-minute livestream; five teenagers were arrested. Discord has three business days to implement the suspension and could face fines of up to 50 million reais (about $10 million) per violation. Regulators criticized the March addition of end-to-end encryption to Go Live for limiting real-time content detection, and are also investigating Discord's age-verification and content-removal practices, while a parallel probe tied neo-Nazi recruitment communities to Telegram.
