That’s why adware trojans, malware that downloaded and installed other software, and trojans capable of downloading and executing arbitrary code, were among the most common threats on Android. Banking trojans also posed a significant threat whilst their activity increased. Moreover, users often encountered various adware apps. --------------------------------------------- https://news.drweb.com/show/?i=14395&lng=en&c=9 ∗∗∗ Doctor Web’s annual virus activity review for 2021 ∗∗∗ --------------------------------------------- Among the most popular threats in 2021 were numerous malware. Among them were trojan droppers destined to distribute malicious malware, and trojan downloader modifications–they download and run executable files with various payloads on the victims computer. Besides that, cybercriminals were actively distributing backdoors. Among the email threats, the most popular were stealers and various backdoor modifications written in VB.NET. --------------------------------------------- https://news.drweb.com/show/?i=14393&lng=en&c=9 ∗∗∗ Spyware Blitzes Compromise, Cannibalize ICS Networks ∗∗∗ --------------------------------------------- The brief spearphishing campaigns spread malware and use compromised networks to steal credentials that can be sold or used to commit financial fraud. --------------------------------------------- https://threatpost.com/spyware-blitzes-compromise-cannibalize-ics-networks/… ∗∗∗ AccessPress Themes Hit With Targeted Supply Chain Attack ∗∗∗ --------------------------------------------- Security researchers at Automattic recently reported that the popular WordPress plugin and theme authors AccessPress were compromised and their software replaced with backdoored versions.

Process injection is a common attacker’s technique these days (for a long time already). The difference, in this case, is that the payload is delivered through FTP! It’s pretty unusual because FTP is today less and less used for multiple reasons (lack of encryption by default, complex to filter with those passive/active modes). --------------------------------------------- https://blog.rootshell.be/2022/01/20/sans-isc-redline-stealer-delivered-thr… ∗∗∗ Kritische Sicherheitslücke in Google Chrome geschlossen ∗∗∗ --------------------------------------------- In der aktualisierten Version von Google Chrome schließt das Unternehmen zahlreiche Schwachstellen.

However, a zero-click attack against the Windows Zoom client was recently revealed at Pwn2Own, showing that it does indeed have a fully remote attack surface.

Sie versprechen ihnen hohe Geldbeträge für anzügliche Fotos oder spielen vor, an der Finanzierung des Lifestyles der betroffenen Personen interessiert zu sein.

We recently set out to explore this topic and validate our theory that this type of “perfect crime” could be a new reality in cyber security. In this blog, we’ll explain how we were able to obtain large amounts of sensitive data using Google’s VirusTotal service in combination with other known malware services and hacker forums. --------------------------------------------- https://safebreach.com/blog/2022/the-perfect-cyber-crime/ ∗∗∗ CVE-2022-21661: Exposing Database Info via WordPress SQL Injection ∗∗∗ --------------------------------------------- In October of this year, we received a report from ngocnb and khuyenn from GiaoHangTietKiem JSC covering a SQL injection vulnerability in WordPress. The bug could allow an attacker to expose data stored in a connected database. This vulnerability was recently addressed as CVE-2022-21661 (ZDI-22-220).

In versions up to 4.00.3038 included, one of the suite’s programs is an executable named ListCheck.exe, which runs at logon with the highest privilege available and suffers from a phantom DLL hijacking.

[..] In einem Twitter-Beitrag, den er am Montag veröffentlichte, erklärte er auch, dass es sich bei dem Fehler nicht um eine Schwachstelle in der Infrastruktur von Tesla handelt. Es sei der Fehler der Besitzer*innen. Weiters schreibt Colombo, dass er das Problem an das Sicherheitsteam von Tesla gemeldet hat, das die Angelegenheit untersucht. --------------------------------------------- https://futurezone.at/digital-life/19-jaehriger-hacker-25-teslas-in-13-laen… ∗∗∗ Adobe Cloud Abused to Steal Office 365, Gmail Credentials ∗∗∗ --------------------------------------------- Threat actors are creating accounts within the Adobe Cloud suite and sending images and PDFs that appear legitimate to target Office 365 and Gmail users, researchers from Avanan discovered. --------------------------------------------- https://threatpost.com/adobe-cloud-steal-office-365-gmail-credentials/17762… ∗∗∗ Decrypting Qakbot’s Encrypted Registry Keys ∗∗∗ --------------------------------------------- One new skill is to insert encrypted data into the registry. One of the requests we received from Trustwave’s DFIR and Global Threats Operations teams is for us to decrypt the registry data that Qakbot created.

After several follow-ups a patched version of “Login/Signup Popup” was released on November 24, 2021, while patched versions of “Side Cart Woocommerce (Ajax)” and “Waitlist Woocommerce ( Back in stock notifier )” were released on December 17, 2021.

As far as real world goes, many servers do not, in fact, defend themselves against NTLM relay attacks. Since the vulnerability is present on all supported Windows versions as of today (as well as all unsupported versions which we had security-adopted), we decided to fix it ourselves. --------------------------------------------- https://blog.0patch.com/2022/01/free-micropatches-for-remotepotato0.html ∗∗∗ Code-Signatur-Prozesse sichern ∗∗∗ --------------------------------------------- DevOps steht unter Druck, wie unter anderem bei der Attacke auf SolarWinds offenkundig wurde.
