TL;DRResidential proxies are intermediaries that allow an Internet connection to appear as coming from another host; This method allows a user to hide the real origin and get an enhanced privacy or an access to geo-restricted content; Residential proxies represent a growing threat in cyberspace, frequently used by attacker groups to hide among legitimate traffic, but also in a legitimate way; The ecosystem of these proxies is characterised by a fragmented and deregulated offering in legitimate and cybercrime webmarkets; To obtain an infrastructure up to several million hosts, residential proxies providers use techniques that can mislead users who install third-party software; With millions of IP addresses available, they represent a massive challenge to be detected by contemporary security solutions; Defending against this threat requires increased vigilance over the origin of traffic, which may not be what it seems, underlining the importance of a cautious and informed approach to managing network traffic; This joint report is built on extensive research from Sekoia.io…Microsoft 365 (formerly Office 365) is Microsoft’s cloud-based suite of productivity tools, which includes email, collaboration platforms, and office applications. All are integrated with Entra ID (referred to as Azure AD in this post) for identity and access management. M365’s centralized storage of organizational data, combined with its ubiquity and widespread adoption, make it a common target of threat actors.…

Successful exploitation of these vulnerabilities allowed adversaries to gain unauthorized access and control over affected systems. The exploitation of these vulnerabilities was named “SlashAndGrab” by Huntress, due to the simplicity of adding a single forward slash character to the end of the address of a vulnerable ScreenConnect installation.…
ESET researchers discovered a cyberespionage campaign that, since at least September 2023, has been victimizing Tibetans through a targeted watering hole (also known as a strategic web compromise), and a supply-chain compromise to deliver trojanized installers of Tibetan language translation software. The attackers aimed to deploy malicious downloaders for Windows and macOS to compromise website visitors with MgBot and a backdoor that, to the best of our knowledge, has not been publicly documented yet; we have named it Nightdoor.…
Recent discussion around an emerging information-stealing trojan project reinforces the continual need to track intelligence on capabilities adversaries rely on for the collection of sensitive information from victims.
