Hackers Target Ukrainian Software Company Using GoMet Backdoor

July 21, 2022
Ukrainian Software Company

A huge software application growth business whose software application is made use of by various state entities in Ukraine went to the obtaining end of an “unusual” item of malware, brand-new research study has actually discovered.

The malware, very first observed on the early morning of Might 19, 2022, is a custom-made version of the open resource backdoor referred to as GoMet and also is created for preserving consistent accessibility to the network.

” This gain access to might be leveraged in a range of means consisting of much deeper gain access to or to release extra assaults, consisting of the possibility for software application supply chain concession,” Cisco Talos said in a record shown to The Cyberpunk Information.


Although there are no concrete signs connecting the assault to a solitary star or team, the cybersecurity company’s evaluation indicate Russian nation-state task.

Public reporting right into making use of GoMet in real-world assaults has actually thus far discovered just 2 recorded instances to day: one in 2020, accompanying the disclosure of CVE-2020-5902, an essential remote code implementation imperfection in F5’s BIG-IP networking tools.

The 2nd circumstances required the effective exploitation of CVE-2022-1040, a remote code implementation susceptability in Sophos Firewall program, by an unrevealed innovative consistent risk (APT) team previously this year.

” We have not seen GoMet released throughout the various other companies we have actually been functioning very closely with and also keeping track of to make sure that indicates it is targeted somehow however might be being used versus extra targets we do not have presence right into,” Nick Biasini, head of outreach for Cisco Talos, informed The Cyberpunk Information.

” We have actually additionally performed reasonably extensive historical evaluation and also see extremely little use GoMet traditionally which better suggests that it is being made use of in extremely targeted means.”

GoMet, as the name indicates, is created in Go and also includes attributes that permit the aggressor to from another location commandeer the endangered system, consisting of posting and also downloading and install data, running approximate commands, and also making use of the first grip to circulate to various other networks and also systems through what’s called a daisy chain.


One more noteworthy function of the dental implant is its capacity to run scheduled tasks making use ofcron While the initial code is set up to carry out cron tasks as soon as every hr, the changed variation of the backdoor made use of in the assault is developed to run every 2 secs and also identify if the malware is attached to a command-and-control web server.

” Most of the assaults we have actually been seeing recently relate to gain access to, either straight or via credential purchase,” Biasini stated. “This is one more instance of that with GoMet being released as a backdoor.”

” When the gain access to has actually been developed, extra reconnaissance and also even more extensive procedures can comply with. We’re functioning to eliminate the assaults prior to they reach this phase so it’s challenging to anticipate the sorts of follow-on assaults.”

The searchings for come as the united state Cyber Command on Wednesday shared the signs of concession (IoCs) referring to various sorts of malware such as GrimPlant, GraphSteel, Cobalt Strike Sign, and also MicroBackdoor targeting Ukrainian networks in current months.

Cybersecurity company Mandiant has considering that attributed the phishing assaults to 2 reconnaissance stars tracked as UNC1151 (also known as Ghostwriter) and also UNC2589, the latter of which is believed to “act on behalf of Russian federal government rate of interest and also has actually been carrying out considerable reconnaissance collection in Ukraine.”
