Russian Hackers Linked to 'Largest Ever Cyber Attack' on Danish Critical Infrastructure

Russian Hackers Linked to 'Largest Ever Cyber Attack' on Danish Critical Infrastructure

Nov 16, 2023 Cyber Warfare / Threat Intelligence
Russian threat actors have been possibly linked to what's been described as the "largest cyber attack against Danish critical infrastructure," in which 22 companies associated with the operation of the country's energy sector were targeted in May 2023.  "22 simultaneous, successful cyberattacks against Danish critical infrastructure are not commonplace," Denmark's SektorCERT  said  [PDF]. "The attackers knew in advance who they were going to target and got it right every time. Not once did a shot miss the target." The agency said it found evidence connecting one or more attacks to Russia's GRU military intelligence agency, which is also tracked under the name  Sandworm  and has a track record of orchestrating disruptive cyber assaults on industrial control systems. This assessment is based on artifacts communicating with IP addresses that have been traced to the hacking crew. The unprecedented and coordinated cyber attacks took place on
Russian Hackers Sandworm Cause Power Outage in Ukraine Amidst Missile Strikes

Russian Hackers Sandworm Cause Power Outage in Ukraine Amidst Missile Strikes

Nov 10, 2023 Cyber Warfare / Network Security
The notorious Russian hackers known as  Sandworm  targeted an electrical substation in Ukraine last year, causing a brief power outage in October 2022. The findings come from Google's Mandiant, which described the hack as a "multi-event cyber attack" leveraging a novel technique for impacting industrial control systems (ICS). "The actor first used OT-level living-off-the-land ( LotL ) techniques to likely trip the victim's substation circuit breakers, causing an unplanned power outage that coincided with mass missile strikes on critical infrastructure across Ukraine," the company  said . "Sandworm later conducted a second disruptive event by deploying a new variant of  CaddyWiper  in the victim's IT environment." The threat intelligence firm did not reveal the location of the targeted energy facility, the duration of the blackout, and the number of people who were impacted by the incident. The development marks Sandworm's  continuous
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a

Russian Sandworm Hackers Impersonate Ukrainian Telecoms to Distribute Malware

Sep 20, 2022
A threat cluster linked to the Russian nation-state actor tracked as Sandworm has continued its targeting of Ukraine with commodity malware by masquerading as telecom providers, new findings show. Recorded Future said it discovered new infrastructure belonging to UAC-0113 that mimics operators like Datagroup and EuroTransTelecom to deliver payloads such as  Colibri loader  and  Warzone RAT . The attacks are said to be an expansion of the  same campaign  that previously distributed  DCRat  (or DarkCrystal RAT) using phishing emails with legal aid-themed lures against providers of telecommunications in Ukraine. Sandworm is a  destructive Russian threat group  that's best known for carrying out attacks such as the 2015 and 2016 targeting of Ukrainian electrical grid and 2017's NotPetya attacks. It's confirmed to be Unit 74455 of Russia's GRU military intelligence agency. The adversarial collective, also known as Voodoo Bear, sought to damage high-voltage electrical s

Russian Hackers Tried Attacking Ukraine's Power Grid with Industroyer2 Malware

Russian Hackers Tried Attacking Ukraine's Power Grid with Industroyer2 Malware

Apr 13, 2022
The Computer Emergency Response Team of Ukraine (CERT-UA) on Tuesday  disclosed  that it thwarted a cyberattack by Sandworm , a hacking group affiliated with Russia's military intelligence, to sabotage the operations of an unnamed energy provider in the country. "The attackers attempted to take down several infrastructure components of their target, namely: Electrical substations, Windows-operated computing systems, Linux-operated server equipment, [and] active network equipment," the State Service of Special Communications and Information Protection of Ukraine (SSSCIP)  said  in a statement. Slovak cybersecurity firm ESET, which collaborated with CERT-UA to analyze the attack, said the attempted intrusion involved the use of ICS-capable malware and regular disk wipers, with the adversary unleashing an updated variant of the  Industroyer  malware, which was first deployed in a 2016 assault on Ukraine's power grid. "The Sandworm attackers made an attempt to d
