Ransomware Group FIN12 Aggressively Going After Healthcare Targets

Ransomware Group FIN12 Aggressively Going After Healthcare Targets

October 08, 2021Ravie Lakshmanan
An "aggressive" financially motivated threat actor has been identified as linked to a string of RYUK ransomware attacks since October 2018, while maintaining close partnerships with TrickBot-affiliated threat actors and using a publicly available arsenal of tools such as Cobalt Strike Beacon payloads to interact with victim networks. Cybersecurity firm Mandiant attributed the intrusions to a Russian-speaking hacker group rechristened as FIN12, and previously tracked under the name  UNC1878 , with a disproportionate focus on healthcare organizations with more than $300 million in revenue, among others, including education, financial, manufacturing, and technology sectors, located in North America, Europe, and the Asia Pacific. The designation marks the first time a ransomware affiliate group has been promoted to the status of a distinct threat actor. "FIN12 relies on partners to obtain initial access to victim environments," Mandiant researchers  said . "Not

Experts Shed Light On New Russian Malware-as-a-Service Written in Rust

August 12, 2021Ravie Lakshmanan
A nascent information-stealing malware sold and distributed on underground Russian underground forums has been written in Rust, signalling a new trend where threat actors are increasingly adopting  exotic programming languages  to bypass security protections, evade analysis, and hamper reverse engineering efforts. Dubbed " Ficker Stealer ," it's notable for being propagated via Trojanized web links and compromised websites, luring in victims to scam landing pages purportedly offering free downloads of  legitimate paid services  like Spotify Music, YouTube Premium, and other Microsoft Store applications. "Ficker is sold and distributed as Malware-as-a-Service (MaaS), via underground Russian online forums," BlackBerry's research and intelligence team said in a report published today. "Its creator, whose alias is @ficker, offers several paid packages, with different levels of subscription fees to use their malicious program." First seen in the wi

Hackers Exploit IT Monitoring Tool Centreon to Target Several French Entities

February 15, 2021Ravie Lakshmanan
Russia-linked state-sponsored threat actor known as Sandworm has been linked to a three-year-long stealthy operation to hack targets by exploiting an IT monitoring tool called Centreon . The intrusion campaign — which breached "several French entities" — is said to have started in late 2017 and lasted until 2020, with the attacks particularly impacting web-hosting providers, said the French information security agency ANSSI in an advisory. "On compromised systems, ANSSI discovered the presence of a backdoor in the form of a webshell dropped on several Centreon servers exposed to the internet," the agency  said  on Monday. "This backdoor was identified as being the PAS webshell, version number 3.1.4. On the same servers, ANSSI found another backdoor identical to one described by ESET and named Exaramel." The Russian hacker group (also called APT28, TeleBots, Voodoo Bear, or Iron Viking) is said to be behind some of the most devastating cyberattacks in p
Researchers Find Links Between Sunburst and Russian Kazuar Malware

Researchers Find Links Between Sunburst and Russian Kazuar Malware

January 11, 2021Ravie Lakshmanan
Cybersecurity researchers, for the first time, may have found a potential connection between the backdoor used in  the SolarWinds hack  to a previously known malware strain. In new  research  published by Kaspersky researchers today, the cybersecurity firm said it discovered several features that overlap with another backdoor known as  Kazuar , a .NET-based malware first documented by Palo Alto Networks in 2017. Disclosed early last month, the  espionage campaign  was notable for its scale and stealth, with the attackers leveraging the trust associated with SolarWinds Orion software to infiltrate government agencies and other companies so as to deploy a custom malware codenamed "Sunburst." Shared Features Between Sunburst and Kazuar Attribution for the SolarWinds supply-chain compromise has been difficult in part due to little-to-no clues linking the attack infrastructure to previous campaigns or other well-known threat groups. But Kaspersky's latest analysis of th

Experts Uncover 'Crutch' Russian Malware Used in APT Attacks for 5 Years

Cybersecurity researchers today took the wraps off a previously undocumented backdoor and document stealer that has been deployed against specific targets from 2015 to early 2020. Codenamed " Crutch " by ESET researchers, the malware has been attributed to  Turla  (aka Venomous Bear or Snake), a Russia-based advanced hacker group known for its extensive attacks against governments, embassies, and military organizations through various watering hole and spear-phishing campaigns. "These tools were designed to exfiltrate sensitive documents and other files to Dropbox accounts controlled by Turla operators," the cybersecurity firm said in an analysis shared with The Hacker News. The backdoor implants were secretly installed on several machines belonging to the Ministry of Foreign Affairs in an unnamed country of the European Union. Besides identifying strong links between a Crutch sample from 2016 and Turla's yet another second-stage backdoor called  Gazer , t

A Russian hacker who was found guilty of  hacking LinkedIn ,  Dropbox , and Formspring over eight years ago has finally been  sentenced  to 88 months in United States prison, that's more than seven years by a federal court in San Francisco this week. Yevgeniy Aleksandrovich Nikulin , 32, of Moscow hacked into servers belonging to three American social media firms, including LinkedIn, Dropbox, and now-defunct social-networking firm Formspring, and stole data on over 200 million users. Between March and July 2012, Nikulin hacked into the computers of LinkedIn,  Dropbox, and Formspring , and installed malware on them, which allowed him to remotely download user databases of over  117 Million LinkedIn  users and more than  68 Million Dropbox  users. According to the prosecutor, Nikulin also worked with unnamed co-conspirators of a Russian-speaking cybercriminal forum to sell customer data he stole as a result of his hacks. Besides hacking into the three social media firms, Nikulin
