    Sairaala saastui haittaohjelmasta – syyksi paljastui pieni huomaamaton uhka https://www.is.fi/digitoday/tietoturva/art-2000009733643.html

    Terveydenhuollon asiantuntija matkusti Aasiaan konferenssiin. Siellä hän jakoi esityksensä muille kytkemällä usb-tikkunsa heidän kannettaviin tietokoneisiinsa. Yksi näistä koneista sisälsi HopperTick-haittaohjelman, joka saastutti usb-tikun. Asiantuntijan palatessa kotiinsa, hän tuli saastuttaneeksi eurooppalaisen sairaalan haittaohjelmalla.

    Tietoturvayhtiö Check Pointin kuvaama todellisen elämän tapaus alkuvuodelta on tärkeä muistutus usb-tikkujen avulla tehtävistä hyökkäyksistä

    VirusTotal apologizes for data leak affecting 5,600 customers https://www.bleepingcomputer.com/news/security/virustotal-apologizes-for-data-leak-affecting-5-600-customers/

    VirusTotal apologized on Friday for leaking the information of over 5,600 customers after an employee mistakenly uploaded a CSV file containing their info to the platform last month.

    The data leak impacted only Premium account customers, with the uploaded file containing their names and corporate email addresses.

    Emiliano Martines, the online malware scanning service’s head of product management, also assured impacted customers that the incident was caused by human error and was not the result of a cyber-attack or any vulnerability with VirusTotal.

    https://arstechnica.com/security/2023/07/ddos-botnets-are-still-feeding-on-zyxel-devices-with-vulnerable-critical-flaw/

    Organizations that have yet to patch a 9.8-severity vulnerability in network devices made by Zyxel have emerged as public nuisance No. 1 as a sizable number of them continue to be exploited and wrangled into botnets that wage DDoS attacks.

    Zyxel patched the flaw on April 25. Five weeks later, Shadowserver, an organization that monitors Internet threats in real time, warned that many Zyxel firewalls and VPN servers had been compromised in attacks that showed no signs of stopping. The Shadowserver assessment at the time was: “If you have a vulnerable device exposed, assume compromise.”

    Kyberhyökkäys Norjaa vastaan – 12 eri ministeriötä kohteena https://www.tivi.fi/uutiset/tv/74cbc42b-6a66-495d-86a4-b08d5991d33a

    Kahteentoista Norjan ministeriöön on kohdistunut kyberhyökkäys, maan hallitus kertoi maanantaina.

    ”Havaitsimme haavoittuvuuden erään toimittajamme alustassa. Tämä haavoittuvuus on nyt korjattu”, kertoi Norjan hallituksen palveluista vastaavan Departementenes sikkerhets- og serviceorganisasjon -viraston (DSS) johtaja Erik Hope lehdistötilaisuudessa.

    Hopen mukaan hyökkäykset havaittiin 12. heinäkuuta epätavallisen verkkoliikenteen johdosta. Hänen mukaansa on vielä liian aikaista sanoa, mikä taho on hyökkäyksen takana ja miten laaja hyökkäys on ollut. Hän ei myöskään kertonut lisätietoja haavoittuvuuden luonteesta, alustasta tai sen toimittajasta.

    Clop now leaks data stolen in MOVEit attacks on clearweb sites https://www.bleepingcomputer.com/news/security/clop-now-leaks-data-stolen-in-moveit-attacks-on-clearweb-sites/

    The Clop ransomware gang is copying an ALPHV ransomware gang extortion tactic by creating Internet-accessible websites dedicated to specific victims, making it easier to leak stolen data and further pressuring victims into paying a ransom.

    When a ransomware gang attacks a corporate target, they first steal data from the network and then encrypt files. This stolen data is used as leverage in double-extortion attacks, warning victims that the data will be leaked if a ransom is not paid.

    North Korea Leverages SaaS Provider in a Targeted Supply Chain Attack https://www.mandiant.com/resources/blog/north-korea-supply-chain

    In July 2023, Mandiant Consulting responded to a supply chain compromise affecting a US-based software solutions entity. We believe the compromise ultimately began as a result of a sophisticated spear phishing campaign aimed at JumpCloud, a zero-trust directory platform service used for identity and access management.

    JumpCloud reported this unauthorized access impacted fewer than five customers and less than 10 devices.The details in this blog post are based on Mandiant’s investigation into the attack against one of JumpCloud’s impacted customers.

    Code Execution Vulnerability Impacts 900k MikroTik Devices

    Over 900,000 devices are impacted by an arbitrary code execution vulnerability in MikroTik RouterOS.

    https://www.securityweek.com/code-execution-vulnerability-impacts-900k-mikrotik-devices/

    More than 900,000 MikroTik devices are impacted by a RouterOS vulnerability leading to arbitrary code execution, vulnerability intelligence provider VulnCheck reports.

    Tracked as CVE-2023-30799 (CVSS score of 9.1), the issue is described as a privilege escalation bug impacting RouterOS versions before 6.49.7 and RouterOS long-term versions through 6.48.6.

    “A remote and authenticated attacker can escalate privileges from admin to super-admin on the Winbox or HTTP interface. The attacker can abuse this vulnerability to execute arbitrary code on the system,” a NIST advisory reads.

    The vulnerability was initially disclosed in June 2022, at the REcon conference, but no CVE identifier was assigned to it. Proof-of-concept (PoC) code demonstrating how a root shell can be obtained on a RouterOS x86 virtual machine was also published at the time.

    MikroTik patched the bug in RouterOS stable 6.49.7 in October 2022, without detailing it, VulnCheck says. Patches were released for the RouterOS long-term version as well.
