===================== = End-of-Day report = ===================== Timeframe: Montag 01-09-2025 18:00 − Dienstag 02-09-2025 18:00 Handler: Alexander Riepl Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ Zscaler data breach exposes customer info after Salesloft Drift compromise ∗∗∗ --------------------------------------------- In an advisory, Zscaler says that its Salesforce instance was impacted by this supply-chain attack, exposing customers' information. [..] This warning follows the compromise of Salesloft Drift, an AI chat agent that integrates with Salesforce, in which attackers stole OAuth and refresh tokens, enabling them to gain access to customer Salesforce environments and exfiltrate sensitive data. [..] The company stresses that the data breach only impacts its Salesforce instance and no Zscaler products, services, or infrastructure. --------------------------------------------- https://www.bleepingcomputer.com/news/security/zscaler-data-breach-exposes-… ∗∗∗ Stolen OAuth tokens expose Palo Alto customer data ∗∗∗ --------------------------------------------- Palo Alto Networks is writing to customers that may have had commercially sensitive data exposed after criminals used stolen OAuth credentials lifted from the Salesloft Drift break-in to gain entry to its Salesforce instance. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2025/09/02/stolen_oauth… ∗∗∗ No, Google did not warn 2.5 billion Gmail users to reset passwords ∗∗∗ --------------------------------------------- This is just the latest such story, which numerous news websites and cybersecurity companies have reported without verification in recent years. [..] However, as the company explained on a Monday blog post addressing these inaccurate stories, "Gmail's protections are strong and effective, and claims of a major Gmail security warning are false." --------------------------------------------- https://www.bleepingcomputer.com/news/technology/no-google-did-not-warn-25-… ∗∗∗ Badges, behavior, and BMS: Why the human perimeter matters in energy cybersecurity ∗∗∗ --------------------------------------------- Over the summer, a hacker brought a 158-year-old European technology company to its knees with a guessed password. By identifying a weak admin credential, the attacker gained access to internal systems and extracted sensitive information, laying the groundwork for a broader ransomware campaign. [..] Energy cybersecurity is not just about software protection —it’s also about managing human interaction and physical access to critical infrastructure. [..] Even the most secure system in the world won’t help if someone holds the door open for the wrong person. --------------------------------------------- https://blog.se.com/digital-transformation/cybersecurity/2025/09/01/badges-… ∗∗∗ Cookies and how to bake them: what they are for, associated risks, and what session hijacking has to do with it ∗∗∗ --------------------------------------------- Kaspersky experts explain the different types of cookies, how to configure them correctly, and how to protect yourself from session hijacking attacks. --------------------------------------------- https://securelist.com/cookies-and-session-hijacking/117390/ ∗∗∗ A quick look at sextortion at scale: 1,900 messages and 205 Bitcoin addresses spanning four years, (Tue, Sep 2nd) ∗∗∗ --------------------------------------------- What can almost 2,000 sextortion messages tell us about how threat actors operate and whether they are successful? [..] The use of specific cryptocurrency addresses in sextortion messages seems to be fairly short-lived. Approximately 46% of the addresses in the dataset were only used for a single day [..] the average requested amount was 1,716 USD, with a median of 1,370 USD [..] Of the 205 cryptocurrency addresses in our dataset, only 57 (~28%) didn’t receive any payment at all, while the remaining addresses did. --------------------------------------------- https://isc.sans.edu/diary/rss/32252 ∗∗∗ Ukrainian Network FDN3 Launches Massive Brute-Force Attacks on SSL VPN and RDP Devices ∗∗∗ --------------------------------------------- Cybersecurity researchers have flagged a Ukrainian IP network for engaging in massive brute-force and password spraying campaigns targeting SSL VPN and RDP devices between June and July 2025. The activity originated from a Ukraine-based autonomous system FDN3 (AS211736), per French cybersecurity company Intrinsec. --------------------------------------------- https://thehackernews.com/2025/09/ukrainian-network-fdn3-launches-massive.h… ∗∗∗ Achtung, Bitpanda-Phishing: Krypto-Guthaben in Gefahr! ∗∗∗ --------------------------------------------- Kriminelle versenden SMS-Nachrichten und warnen vor einem angeblichen Login auf das Bitpanda-Konto des Opfers. Sie liefern außerdem eine Telefonnummer mit, bei der man sich zur Klärung melden solle. Am anderen warten allerdings die Betrüger:innen – und die haben es auf Krypto-Assets abgesehen. --------------------------------------------- https://www.watchlist-internet.at/news/achtung-bitpanda-phishing-krypto/ ===================== = Vulnerabilities = ===================== ∗∗∗ Heimautomatisierung: ESPHome-Lücke erlaubt volle Kompromittierung ∗∗∗ --------------------------------------------- In der ESP-IDF-Plattform der ESPHome-Firmwarebasis führt eine nun entdeckte Sicherheitslücke dazu, dass Angreifer eine Authentifizierung umgehen können. Das ermöglicht ihnen sogar, eigene Firmware auf verwundbare Controller zu verfrachten. [..] Ein neuer Schwachstelleneintrag vom Montag dieser Woche erörtert die Sicherheitslücke in der Firmware. [..] (CVE-2025-57808 / noch kein EUVD, CVSS 8.1, Risiko "hoch") --------------------------------------------- https://www.heise.de/news/Heimautomatisierung-ESPHome-Luecke-erlaubt-volle-… ∗∗∗ Security updates for Tuesday ∗∗∗ --------------------------------------------- Security updates have been issued by AlmaLinux (kernel, mod_http2, postgresql, postgresql:15, and python39:3.9), Debian (libsndfile), Mageia (ceph, glibc, and golang), Oracle (postgresql and python39:3.9), Red Hat (aide, postgresql:12, postgresql:13, postgresql:15, and postgresql:16), SUSE (git, govulncheck-vulndb, jetty-minimal, nginx, python-future, and ruby2.5), and Ubuntu (imagemagick). --------------------------------------------- https://lwn.net/Articles/1036369/ ∗∗∗ TYPO3-EXT-SA-2025-011: Command Injection in extension "TYPO3 Backup Plus" (ns_backup) ∗∗∗ --------------------------------------------- https://typo3.org/security/advisory/typo3-ext-sa-2025-011 ∗∗∗ Delta Electronics EIP Builder ∗∗∗ --------------------------------------------- https://www.cisa.gov/news-events/ics-advisories/icsa-25-245-01 ∗∗∗ SunPower PVS6 ∗∗∗ --------------------------------------------- https://www.cisa.gov/news-events/ics-advisories/icsa-25-245-03 ∗∗∗ Fuji Electric FRENIC-Loader 4 ∗∗∗ --------------------------------------------- https://www.cisa.gov/news-events/ics-advisories/icsa-25-245-02 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/mailman3/postorius/lists/daily.lists.cert.at/
