Cobalt Strike | Breaking Cybersecurity News | The Hacker News

Researchers on Monday took the wraps off a newly discovered Linux and Windows re-implementation of  Cobalt Strike Beacon  that's actively set its sights on government, telecommunications, information technology, and financial institutions in the wild. The as-yet undetected version of the penetration testing tool — codenamed "Vermilion Strike" — marks one of the  rare Linux ports , which has been traditionally a Windows-based red team tool heavily repurposed by adversaries to mount an array of targeted attacks. Cobalt Strike bills itself as a " threat emulation software ," with Beacon being the payload engineered to model an advanced actor and duplicate their post-exploitation actions. "The stealthy sample uses Cobalt Strike's command-and-control (C2) protocol when communicating to the C2 server and has remote access capabilities such as uploading files, running shell commands and writing to files," Intezer researchers said in a report publishe...

Organizations' cybersecurity capabilities have improved over the past decade, mostly out of necessity. As their defenses get better, so do the methods, tactics, and techniques malicious actors devise to penetrate their environments. Instead of the standard virus or trojan, attackers today will deploy a variety of tools and methods to infiltrate an organization's environment and attack it from the inside. In an interesting twist of fate, one of the tools organizations have used to audit and improve their defenses has also become a popular tool attackers use to infiltrate. Cobalt Strike is an Adversary Simulation and Red Team Operations tool that allows organizations to simulate advanced attacks and test their security stacks in a close-to-real-world simulation. A new research webinar from XDR provider Cynet ( register here ) offers a better look at Cobalt Strike. The webinar, led by Cyber Operations Analyst for the Cynet MDR Team Yuval Fischer, will take a deep dive into the thr...

Security researchers have tracked down activities of a new group of financially-motivated hackers that are targeting several businesses and organizations in Germany, Italy, and the United States in an attempt to infect them with backdoor, banking Trojan, or ransomware malware. Though the new malware campaigns are not customized for each organization, the threat actors appear to be more interested in businesses, IT services, manufacturing, and healthcare industries who possess critical data and can likely afford high ransom payouts. According to a report ProofPoint shared with The Hacker News, the newly discovered threat actors are sending out low-volume emails impersonating finance-related government entities with tax assessment and refund lured emails to targeted organizations. "Tax-themed Email Campaigns Target 2019 Filers, finance-related lures have been used seasonally with upticks in tax-related malware and phishing campaigns leading up to the annual tax filing deadlines in...

Three members of one of the world's largest cybercrime organizations that stole over a billion euros from banks across the world over the last five years have been indicted and charged with 26 felony counts, the Justice Department announced on Wednesday. The three suspects are believed to be members of the organized Russian cybercrime group known as FIN7 , the hackers group behind Carbanak and Cobalt malware and were arrested last year in Europe between January and June. The suspects—Dmytro Fedorov, 44, Fedir Hladyr, 33, and Andrii Kopakov, 30—are all from Ukraine and accused of targeting 120 companies based in the United States, as well as U.S. individuals. The victims include Chipotle Mexican Grill, Jason's Deli, Red Robin Gourmet Burgers, Sonic Drive-in, Taco John's, Chili's, Arby's, and Emerald Queen Hotel and Casino in Washington state. Carbanak (FIN7) Group Charged for Stealing 15 Million Credit Cards According to the press release published ...

Spanish Police has arrested the alleged leader of an organised Russian cybercrime gang behind the Carbanak and Cobalt malware attacks, which stole over a billion euros from banks worldwide since 2013. In a coordinated operation with law enforcement agencies across the globe, including the FBI and Europol, Police detained the suspected leader of Carbanak hacking group in Alicante, Spain. Carbanak hacking group started its activities almost five years ago by launching a series of malware attack campaigns such as Anunak and Carbanak to compromise banks and ATM networks, from which they swiped millions of credit card details from US-based retailers. According to the Europol, the group later developed a sophisticated heist-ready banking malware known as Cobalt, based on the Cobalt Strike penetration testing software, which was in use until 2016. "The magnitude of the losses is significant: the Cobalt malware alone allowed criminals to steal up to EUR 10 million per heist,...

A recently disclosed severe 17-year-old vulnerability in Microsoft Office that lets hackers install malware on targeted computers without user interaction is now being exploited in the wild to distribute a backdoor malware. First spotted by researchers at security firm Fortinet , the malware has been dubbed Cobalt because it uses a component from a powerful and legitimate penetration testing tool, called Cobalt Strike . Cobalt Strike is a form of software developed for Red Team Operations and Adversary Simulations for accessing covert channels of a system. The vulnerability (CVE-2017-11882) that Cobalt malware utilizes to deliver the backdoor is a memory-corruption issue that allows unauthenticated, remote attackers to execute malicious code on the targeted system when opened a malicious file and potentially take full control over it. This vulnerability impacts all versions of Microsoft Office and Windows operating system, though Microsoft has already released a patch upda...

What if you could easily host malicious websites, send phishing emails, and manage compromised hosts across diverse internet addresses? This week's Cobalt Strike adds the ability to manage multiple attack servers at once. Here's how it works: When you connect to two or more servers, Cobalt Strike will show a switch bar with buttons for each server at the bottom of your window. Click a button to make that server active. It's a lot like using tabs to switch between pages in a web browser. To make use of multiple servers, designate a role for each one. Assign names to each server's button to easily remember its role. Dumbly connecting to multiple servers isn't very exciting. The fun comes when you seamlessly use Cobalt Strike features between servers. For example: Designate one server for phishing and another for reconnaissance. Go to the reconnaissance server, setup the system profiler website. Use the phishing tool to deliver the reconnaissa...
