Background for this topic.
A backdoor is a hidden method within software or hardware that allows bypassing normal authentication to access a system or network. These can be intentionally created by developers for maintenance or debugging but are frequently exploited or implanted by attackers to maintain unauthorized, persistent access. Backdoors often appear as undocumented commands, hidden user accounts, or covert network services designed to evade detection.
In cybersecurity, backdoors enable attackers to circumvent security controls, increasing the risk of prolonged system compromise and data exposure. Detecting backdoors requires careful code review, monitoring for unusual system behavior, and verifying integrity through trusted baselines. Identifying backdoor indicators in malware or attacker infrastructure is critical for limiting unauthorized access and reducing attacker dwell time within networks. Defensive measures focus on eliminating hidden access points and strengthening authentication mechanisms.
North Korean hackers are using trojanized versions of the PuTTY SSH client to deploy backdoors on targets' devices as part of a fake Amazon job assessment. [...]
Researchers link the APT to an attack on a Hong Kong university, which compromised multiple key servers using advanced Linux malware.
Eset also said the same university was targeted during student protests in May 2020
State-backed Chinese hackers have developed a Linux variant for the SideWalk backdoor used against Windows systems belonging to targets in the academic sector. [...]

A Linux variant of a backdoor known as SideWalk was used to target a Hong Kong university in February 2021, underscoring the cross-platform abilities of the implant. Slovak cybersecurity firm ESET, which detected the malware in the university's network, attributed the backdoor to a nation-state actor dubbed SparklingGoblin. The unnamed university is said to have been already targeted by the
