The four issues, which have CVSS scores ranging from medium to critical, can all result in a denial of service (DoS). --------------------------------------------- https://blog.trailofbits.com/2023/01/12/wolfssl-vulnerabilities-tlspuffin-f… ∗∗∗ Bad things come in large packages: .pkg signature verification bypass on macOS ∗∗∗ --------------------------------------------- Besides signing applications, it is also possible to sign installer packages (.pkg files). During a short review of the xar source code, we found a vulnerability (CVE-2022-42841) that could be used to modify a signed installer package without invalidating its signature. This vulnerability could be abused to bypass Gatekeeper, SIP and under certain conditions elevate privileges to root. [..] This was fixed by Apple with a 2 character fix: changing uint32_t to uint64_t in macOS 13.1. --------------------------------------------- https://sector7.computest.nl/post/2023-01-xar/ ∗∗∗ Crassus Windows privilege escalation discovery tool ∗∗∗ --------------------------------------------- Accenture made a tool called Spartacus, which finds DLL hijacking opportunities on Windows. Using Spartacus as a starting point, we created Crassus to extend Windows privilege escalation finding capabilities beyond simply looking for missing files. The ACLs used by files and directories of privileged processes can find more than just looking for missing files to achieve the goal. --------------------------------------------- https://github.com/vullabs/Crassus ∗∗∗ Cyber-Attacken auf kritische Lücke in Control Web Panel ∗∗∗ --------------------------------------------- Cyberkriminelle greifen eine kritische Sicherheitslücke in CWP (Control Web Panel, ehemals CentOS Web Panel) an.

Der Shop hat insbesondere Kinderspielzeug, Brettspiele und Sportgeräte im Sortiment, bietet aber auch Gartenmöbel und Klettergerüste sowie Bettwäsche an. Bezahlt werden soll per Sofortüberweisung. Achtung: Die Daten werden nicht an den Zahlungsdienstleister weitergeleitet, sondern von den Kriminellen abgegriffen.

Gängiger Workaround scheint momentan zu sein, die entsprechenden Regeln auf "Audit" zu setzen. Microsoft hat die Regel wieder entfernt, es kann aber noch dauern, bis das global wirksam wird. Inzwischen wird empfohlen, im Admin Center auf SI MO497128 zu schauen. --------------------------------------------- https://cert.at/de/aktuelles/2023/1/microsoft-asrdefender-update-kann-deskt… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (cacti, cacti-spine, mbedtls, postgresql-jdbc, and rust), Oracle (.NET 6.0, dbus, expat, grub2, kernel, kernel-container, libtasn1, libtiff, sqlite, and usbguard), Red Hat (rh-postgresql10-postgresql), SUSE (php7), and Ubuntu (heimdal, linux, linux-aws, linux-aws-5.15, linux-azure, linux-azure-5.15, linux-gcp, linux-gcp-5.15, linux-hwe-5.15, linux-ibm, linux-kvm, linux-oracle, linux-raspi,, linux, linux-aws, linux-aws-hwe, linux-azure, [...] --------------------------------------------- https://lwn.net/Articles/919907/ ∗∗∗ IBM Security Bulletins 2023-01-13 ∗∗∗ --------------------------------------------- IBM Cloud Pak for Data, IBM Cloud Pak for Security, IBM Security Verify Access Appliance, IBM Watson Speech Services, IBM Watson Speech Services Cartridge for IBM Cloud Pak for Data, IBM Watson Text to Speech and Speech to Text (IBM Watson™ Speech Services 1.1), ICP Speech to Text and Text to Speech --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ ∗∗∗ CISA Releases Twelve Industrial Control Systems Advisories ∗∗∗ --------------------------------------------- https://us-cert.cisa.gov/ncas/current-activity/2023/01/12/cisa-releases-twe… ∗∗∗ Juniper Networks Releases Security Updates for Multiple Products ∗∗∗ --------------------------------------------- https://us-cert.cisa.gov/ncas/current-activity/2023/01/12/juniper-networks-… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

This meant that these data types could only be exfiltrated in single packets, rather than multiple, to avoid exceeding the MTU size. When asked about this finding, the NG-FW vendor acknowledged that "to determine which application is being used, and whether the session aligned with the protocol’s standard, the NG-FW must allow at least one packet to pass." --------------------------------------------- https://cymulate.com/blog/data-exfiltration-firewall/ ∗∗∗ Kritische Sicherheitslücke bedroht End-of-Life-Router von Cisco ∗∗∗ --------------------------------------------- Der Netzwerkausrüster Cisco hat wichtige Sicherheitsupdates für etwa verschiedene Router, IP-Telefone und Webex veröffentlicht. --------------------------------------------- https://heise.de/-7456480 ∗∗∗ AI-generated phishing attacks are becoming more convincing ∗∗∗ --------------------------------------------- Its time for you and your colleagues to become more skeptical about what you read.

This is something to take seriously. It might not be correct, but it’s not obviously wrong. We have long known from Shor’s algorithm that factoring with a quantum computer is easy. But it takes a big quantum computer, on the orders of millions of qbits, to factor anything resembling the key sizes we use today. What the researchers have done is combine classical lattice reduction factoring techniques with a quantum approximate optimization algorithm. --------------------------------------------- https://www.schneier.com/blog/archives/2023/01/breaking-rsa-with-a-quantum-… ∗∗∗ Androids First Security Updates for 2023 Patch 60 Vulnerabilities ∗∗∗ --------------------------------------------- Google announced on Tuesday the first Android security updates for 2023, which patch a total of 60 vulnerabilities. The first part of the update, which arrives on devices as the 2023-01-01 security patch level, addresses 19 security defects in the Framework and System components. --------------------------------------------- https://www.securityweek.com/androids-first-security-updates-2023-patch-60-… ∗∗∗ Ransomware predictions in 2023: more gov’t action and a pivot to data extortion ∗∗∗ --------------------------------------------- There were thousands of ransomware attacks in 2022, from breaches targeting militaries to incidents that brought entire governments to a standstill. Ransomware giants like Conti closed shop, while groups like LockBit and Hive took their place, attacking thousands of hospitals, governments, businesses and schools across the world. So what does 2023 have in store for us? --------------------------------------------- https://therecord.media/ransomware-predictions-in-2023-more-govt-action-and… ∗∗∗ DeTT&CT: Automate your detection coverage with dettectinator ∗∗∗ --------------------------------------------- Last year, I published an article on mapping detection to the MITRE ATT&CK framework using DeTT&CT. In the article, we introduced DeTT&CT and explored its features and usage. If you missed it, you can find the article here. Although, after writing that article, I encountered some challenges. For instance, I considered using DeTT&CT in a production environment but there were hundreds of existing detection rules to consider, and it would have been a tedious process to manually create the necessary YAML file for building a detection coverage layer. --------------------------------------------- https://blog.nviso.eu/2023/01/04/dettct-automate-your-detection-coverage-wi… ∗∗∗ Shc Linux Malware Installing CoinMiner ∗∗∗ --------------------------------------------- The ASEC analysis team recently discovered that a Linux malware developed with Shc has been installing a CoinMiner. It is presumed that after successful authentication through a dictionary attack on inadequately managed Linux SSH servers, various malware were installed on the target system. Among those installed were the Shc downloader, XMRig CoinMiner installed through the former, and DDoS IRC Bot, developed with Perl. --------------------------------------------- https://asec.ahnlab.com/en/45182/ ∗∗∗ Three easy steps to dramatically improve your AWS security posture: Step 1, set up IAM properly ∗∗∗ --------------------------------------------- Have you ever heard the saying that the greatest benefit of the cloud is that limitless resources can be spun-up with just a few clicks of the mouse? If so, you would be best served by forgetting that saying altogether. Just because cloud resources can be spun-up with a few clicks of the mouse does not mean that they should be. Rather, prior to launching anything in the cloud, careful consideration and planning are a necessity. --------------------------------------------- https://cybersecurity.att.com/blogs/security-essentials/three-easy-steps-to… ===================== = Vulnerabilities = ===================== ∗∗∗ January 2023 Vulnerability Advisories ∗∗∗ --------------------------------------------- FortiTester (CVSS Score: 7.6), FortiPortal (CVSS Score: 6.6), FortiWeb (CVSS Score: 5.3), FortiManager (CVSS Score: 6), FortiADC (CVSS Score: 8.6) --------------------------------------------- https://fortiguard.fortinet.com/psirt-monthly-advisory/january-2023-vulnera… ∗∗∗ Security updates for Wednesday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (xorg-x11-server-Xwayland), Red Hat (webkit2gtk3), SUSE (rmt-server), and Ubuntu (freeradius). --------------------------------------------- https://lwn.net/Articles/919051/ ∗∗∗ IBM Security Bulletins 2023-01-04 ∗∗∗ --------------------------------------------- IBM Common Licensings Administration And Reporting Tool (ART), IBM DataPower Gateway, IBM Global Mailbox, IBM Integration Bus, IBM MQ, IBM Security Verify Governance, IBM Sterling Global Mailbox, IBM WebSphere MQ, IBM WebSphere Message Broker, ITNM --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

NTP is lightweight and reasonably accurate in most use cases to synchronize time across the internet with millisecond accuracy [1]. Some protocols, like PTP, are more accurate but are designed for local networks and may require special hardware on the host [2]. Smaller systems with less stringent accuracy requirements sometimes use SNTP, a variant of NTP. --------------------------------------------- https://isc.sans.edu/diary/rss/29394 ∗∗∗ Raspberry Robin Worm Evolves to Attack Financial and Insurance Sectors in Europe ∗∗∗ --------------------------------------------- Financial and insurance sectors in Europe have been targeted by the Raspberry Robin worm, as the malware continues to evolve its post-exploitation capabilities while remaining under the radar. "What is unique about the malware is that it is heavily obfuscated and highly complex to statically disassemble," Security Joes said in a new report published Monday. --------------------------------------------- https://thehackernews.com/2023/01/raspberry-robin-worm-evolves-to-attack.ht… ∗∗∗ Cloud Metadata - AWS IAM Credential Abuse ∗∗∗ --------------------------------------------- [...] In this run through we have a vulnerable AWS EC2 instance configured to use IMDSv1 (Instance Metadata Service) which we will exploit, escalate our privileges and carry out post-compromise activities.
