It was the first known case of native English-speaking hackers in the United States and Britain teaming up with ransomware gangs based in Russia. But that made-for-Hollywood narrative has eclipsed a far more hideous trend: Many of these young, Western cybercriminals are also members of fast-growing online groups that exist solely to bully, stalk, harass and extort vulnerable teens into physically harming themselves and others. --------------------------------------------- https://krebsonsecurity.com/2024/09/the-dark-nexus-between-harm-groups-and-… ∗∗∗ Woo Skimmer Uses Style Tags and Image Extension to Steal Card Details ∗∗∗ --------------------------------------------- This post starts the same way many others do on this blog, and it will be familiar to those who keep up with website security: A client came to us having been notified by their payment processor that credit cards were being stolen from the checkout page of their eCommerce website. The question of course was how? During this investigation we uncovered a very interesting (and in fact, creative) way that threat actors were pilfering credit card details from this compromised website. --------------------------------------------- https://blog.sucuri.net/2024/09/woo-skimmer-uses-style-tags-and-image-exten… ∗∗∗ We can try to bridge the cybersecurity skills gap, but that doesn’t necessarily mean more jobs for defenders ∗∗∗ --------------------------------------------- I have written about the dreaded “cybersecurity skills gap” more times than I can remember in this newsletter, but I feel like it’s time to revisit this topic again. --------------------------------------------- https://blog.talosintelligence.com/threat-source-newsletter-sept-12-2024/ ∗∗∗ FBI and CISA Release Joint PSA, Just So You Know: False Claims of Hacked Voter Information Likely Intended to Sow Distrust of U.S. Elections ∗∗∗ --------------------------------------------- As observed through multiple election cycles, foreign actors and cybercriminals continue to spread false information through various platforms to manipulate public opinion, discredit the electoral process, and undermine confidence in U.S. democratic institutions. The FBI and CISA continue to work closely with federal, state, local, and territorial election partners and provide services and information to safeguard U.S. voting processes and maintain the resilience of the U.S. elections. --------------------------------------------- https://www.cisa.gov/news-events/news/fbi-and-cisa-release-joint-psa-just-s… ===================== = Vulnerabilities = ===================== NTR -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

Exploitation is facilitated by bypassing previous patches. [..] Based on our analysis, three of these vulnerabilities are, essentially, the same vulnerability with the same root cause.

Im ersten Fall kann ein entfernter Angreifer ohne Anmeldung aufgrund von statischen Admin-Zugangsdaten auf Instanzen zugreifen. Mit den Adminrechten des Accounts erlangt ein Angreifer die volle Kontrolle.
