Solarwinds hack turns malicious domain into ‘Killswich’ – Crabs on Security

Network Monitoring Software Key malicious domain name used to control thousands of computer systems, possibly through months of breaches at software vendors Solarwinds Was commanded by security experts and used as a “killswich” designed to carry out sporadic cybercrime operations against itself, Krebson Security has learned.

Texas Stein, Texas-based Solarwinds announced this week that a compromise with its software update servers earlier this year could push malicious code to about 18,000 of its customers. Orion Platform. Many US federal agencies and Fortune 500 companies use (D) Orion to monitor the health of their IT networks.

Cyber ​​event response firm on 13 December Fire Published a detailed article on the warehousing infrastructure used in the Solarwinds settlement, presenting evidence that Orion software was first compromised back in March 2020. avsvmcloud[.]Community – The attackers set up one of several domains to control the affected systems.

According to the first report here on Tuesday, there have been signs in the last few days that control over the domain has shifted. Micro .ft. When asked about the change, Microsoft referred questions to Fire and GoDaddy, The current domain name registrar for the malicious site.

Today, FireA responded that the domain seizure was part of a collaborative effort to prevent the network from being affected by the compromised Solarwinds software software update, which communicated with the attackers. Further, the company said the domain was rearranged to act as a “killswich” that would prevent the maver from continuing under certain circumstances.

“Sunburst is a malware distributed by Solarwinds software,” Fire said in a statement shared with Krebs on Security. “As part of Sunburst’s FireEd analysis, we identified a killswitch that would prevent Sunburst from operating.”

The statement continues:

“When malware solves avsvmcloud it depends on the IP address[.]com, under certain conditions, the malware will terminate itself and prevent further execution. FireA collaborated with GoDaddy and Micros.ft to neutralize the sunburst infection. “

“This will affect new and previous sunburst infections by disabling Killswich sunburst deployments that still do not scare evasquillode.[.]Community. However, in the intrusions that FireA has seen, the actor quickly moved to install additional continuous mechanisms to access victim networks outside the Sunburst door door.

This murder switch will not remove the actor from the victim networks where they have installed other backdoor. However, this will make it more difficult for the actor to take advantage of earlier distributed versions of Sunburst. “

Given that given their visibility and control over the malicious domain, Micro .ft, FireAe, Godaddy and others now have a good idea that companies are still struggling with sunburst infection.

The revelations of the murder came as security investigators said Sunburst’s obscure communication methods progressed in decoding. Chinese cybersecurity firm Reddrip team Publishing his findings on Githob, he said that his decoder tool has identified about 100 suspected victims of Solarwinds / Orion breaches, including universities, governments and high-tech companies.

Meanwhile, the potential legal fallout for Solarwinds continues to worsen following this breach. W. Washington Post Top investors in SolarWinds sold millions of dollars in stock in the days before the intrusion was revealed, it was reported on Tuesday. Solarwinds’ share price has fallen more than 20 percent in the last few days. The post quoted ex-enforcement officers US Securities and Exchange Commission (SEC) said the sale is likely to investigate internal trade.
