∗∗∗ FIN8 Group Using Modified Sardonic Backdoor for BlackCat Ransomware Attacks ∗∗∗
---------------------------------------------
The financially motivated threat actor known as FIN8 has been observed using a "revamped" version of a backdoor called Sardonic to deliver the BlackCat ransomware. According to the Symantec Threat Hunter Team, part of Broadcom, the development is an attempt on the part of the e-crime group to diversify its focus and maximize profits from infected entities.

∗∗∗ Uncovering drIBAN fraud operations. Chapter 3: Exploring the drIBAN web inject kit ∗∗∗
---------------------------------------------
So far, we have discussed the malspam campaign that started spreading sLoad. Then, we discovered that sLoad is a dropper for Ramnit [..] After that, we also described Ramnit’s capabilities, focusing mainly on its injection and persistence techniques. As a final step, we will discuss drIBAN, a sophisticated and modular web-inject kit that can hide resources, masquerade its presence, and perform large-scale ATS attacks.

Sie verkaufen etwas auf Shpock. Sofort meldet sich jemand und möchte es kaufen. Zeitgleich erhalten Sie ein E-Mail von „TeamShpock“ mit der Information, dass die Ware bezahlt wurde und Sie das Geld anfordern können. Sie werden auf eine "Auszahlungsseite" verlinkt. Vorsicht, diese Vorgehensweise ist Betrug. Wir zeigen Ihnen, wie die Betrugsmasche abläuft und wie Sie sicher auf Shpock verkaufen!

∗∗∗ Role-based Access Control and Privilege Management in OpenEdge Management (OEM) and in OpenEdge Explorer (OEE) (CVE-2023-34203) ∗∗∗
---------------------------------------------
Using a local or remote admin service, a logged-in OpenEdge Management (OEM) or OpenEdge Explorer (OEE) user could perform a URL injection attack to change identity or role membership. Only users that are already authorized members of OEM or OEE user roles were able to perform this exploit. Non-admin role members were able to obtain unauthorized escalation to admin role privileges where unrestricted OEM and OEE capabilities were available to the user.

∗∗∗ Bad.Build: A Critical Privilege Escalation Design Flaw in Google Cloud Build Enables a Supply Chain Attack ∗∗∗
---------------------------------------------
The flaw presents a significant supply chain risk since it allows attackers to maliciously tamper with application images, which can then infect users and customers when they install the application. [..] Orca Security immediately reported the findings to the Google Security Team, who investigated the issue and deployed a partial fix. However, Google’s fix doesn’t revoke the discovered Privilege Escalation (PE) vector. It only limits it – turning it into a design flaw that still leaves organizations vulnerable to the larger supply chain risk.
