Cybersecurity researchers warn of a new malicious software called Dslogdrat, which is installed after the exploitation of the already requested security lack of Ivanti Connect Secure (ICS).
The malicious software, along with the web-line, were “established using the vulnerability of the zero day at the time, CVE-2025-0282, during the attacks on the organization in Japan approximately December 2024,” “JPECT/CC Yuma Masubuchi Researcher – Note In a report published on Thursday.
Cve-2025-0282 Refers to a critical lack of security in the IS, which can allow unauthorized execution of the remote code. This was addressed to Ivani in early January 2025.
However, the deficiency was used as a zero day of the Chinese-NEXUS Cyber Spionage Group, dubbed the UNC5337 to deliver the spawning ecosystem of malware, as well as other tools such as Dryhook and Phasejam. The deployment of the last two malware has not been associated with any famous threat actor.
Ever since JPCERT/CC, and the US Cybersecurity Agency and US infrastructure (CISA) have discovered the same vulnerability to provide updated versions of Spyawn called Notification and Rebellion.
Earlier this month is also a Mandiant owned by Google disclosed What is another lack of security in the IS (CVE-2025-22457) was armed for spawning, malicious software attributed to another Chinese hacking group called Unc5221.
JPCERT/CC said it is currently unclear if the attacks using DSLOGDrat are part of the same company associated with the defecting malware managed by UNC5221.
The sequence of the attack set by the agency entails the operation of the CVE-2025-0282 to deploy the Perl shell, which then serves the pipes for deploying additional useful loads, including dslogdrat.
For its part, Dslogdrat initiates contact with the external server through the socket connection to send basic system information and waiting for additional instructions that allow you to execute Shell command commands, download/download files and use infected host as proxy.
Disclosure is going on as a Greynoise Intelligence Firm prevent With “9x Spike with suspicious scan activity” focused on ICS and Ivanti Pulse Secure (IPS) with more than 270 unique IP -Das Over the last 24 hours and more 1000 unique IP -Das In the last 90 days.
Of these 255 IP -Dases, they were assigned to malicious ones, and 643 were marked as suspicious. Malicious IPS was observed using the TOR departure nodes, and suspicious IPS is associated with less famous hosting suppliers. The United States, Germany and the Netherlands make up the top three sources.
“This surge can indicate a coherent intelligence and possible preparation for future operation,” the company said. “Although no specific Cves has not yet been associated with this scanning activity, spikes often preceded by active operation.”
