A previously undocumented backdoor named Msupedge has been put to use against a cyber attack targeting an unnamed university in Taiwan. "The most notable feature of this backdoor is that it communicates with a command-and-control server via DNS traffic," the Symantec Threat Hunter Team, part of Broadcom, said in a report shared with The Hacker News.

Browser extensions are a prime target for cybercriminals. This isn't just a consumer problem - it's a new frontier in enterprises' battle against shadow IT. Ultimately, more extension permissions result in potentially bigger attack surfaces.

The Russian government and IT organizations are the target of a new campaign that delivers a number of backdoors and trojans as part of a spear-phishing campaign codenamed EastWind. The attack chains are characterized by the use of RAR archive attachments containing a Windows shortcut file that, upon opening, activates the infection sequence, culminating in the deployment of malware such as GrewApacha, an updated version of the CloudSorcerer backdoor, and a previously undocumented implant dubbed PlugY. PlugY is "Downloaded through the CloudSorcerer backdoor, has an extensive set of commands and supports three different protocols for communicating with the command-and-control server," Russian cybersecurity company Kaspersky said.

An unnamed media organization in South Asia was targeted in November 20233 using a previously undocumented Go-based backdoor called GoGra. "GoGra is written in Go and uses the Microsoft Graph API...

Cybersecurity researchers have discovered a previously undocumented Windows backdoor that leverages a built-in feature called Background Intelligent Transfer Service as a command-and-control mechanism. The newly identified malware strain has been codenamed BITSLOTH by Elastic Security Labs, which made the discovery on June 25, 2024, in connection with a cyber attack targeting an unspecified Foreign Ministry of a South American government.

The Chinese hacking group tracked as 'Evasive Panda' was spotted using new versions of the Macma backdoor and the Nightdoor Windows malware. [...]

MuddyWater, an Iranian government-backed cyber espionage crew, has upgraded its malware with a custom backdoor, which it's used to target Israeli organizations. It's since moved on to phishing campaigns that deploy a new backdoor - dubbed BugSleep - according to Check Point Research.

Cybersecurity researchers have identified two malicious packages on the npm package registry that concealed backdoor code to execute malicious commands sent from a remote server. The packages in question - img-aws-s3-object-multipart-copy and legacyaws-s3-object-multipart-copy - have been downloaded 190 and 48 times each.

The Iranian nation-state actor known as MuddyWater has been observed using a never-before-seen backdoor as part of a recent attack campaign, shifting away from its well-known tactic of deploying legitimate remote monitoring and management software for maintaining persistent access. "Compared to previous campaigns, this time MuddyWater changed their infection chain and did not rely on the legitimate Atera remote monitoring and management tool as a validator," Sekoia said in a report shared with The Hacker News.
