#backdoor

A China-aligned advanced persistent threat actor known as TA413 weaponized recently disclosed flaws in Sophos Firewall and Microsoft Office to deploy a never-before-seen backdoor called LOWZERO as part of an espionage campaign aimed at Tibetan entities. Targets primarily consisted of organizations associated with the Tibetan community, including enterprises associated with the Tibetan

By Deeba Ahmed According to Microsoft 365 Defender Research Team, in an incident they analyzed, malicious OAuth applications were deployed on compromised cloud tenants, and eventually, attackers took over Exchange servers to carry out spam campaigns. This is a post from HackRead.com Read the original post: New Spam Attack Abusing OAuth Apps to Target Microsoft Exchange Servers

Cybercriminals took control of enterprise Exchange Servers to spread large amounts of spam aimed at signing people up for bogus subscriptions.

Researchers from SentinelLabs laid out what they know about the attackers and implored the researcher community for help in learning more about the shadowy group.

The tactic is just one in a constantly expanding bag of tricks that attackers are using to get users to click on links and open malicious documents.

An attacker can exploit this vulnerability to elevate privileges from ring 0 to ring -2, execute arbitrary code in System Management Mode - an environment more privileged than operating system (OS) and completely isolated from it. Running arbitrary code in SMM additionally bypasses SMM-based SPI flash protections against modifications, which can help an attacker to install a firmware backdoor/implant into BIOS. Such a malicious firmware code in BIOS could persist across operating system re-installs. Additionally, this vulnerability potentially could be used by malicious actors to bypass security mechanisms provided by UEFI firmware (for example, Secure Boot and some types of memory isolation for hypervisors).
