New Ymir Ransomware Exploits Memory for Stealthy Attacks; Targets Corporate Networks

New Ymir Ransomware Exploits Memory for Stealthy Attacks; Targets Corporate Networks

Nov 12, 2024 Cyber Attack / Cybercrime
Cybersecurity researchers have flagged a new ransomware family called Ymir that was deployed in an attack two days after systems were compromised by a stealer malware called RustyStealer. "Ymir ransomware introduces a unique combination of technical features and tactics that enhance its effectiveness," Russian cybersecurity vendor Kaspersky said . "Threat actors leveraged an unconventional blend of memory management functions – malloc, memmove, and memcmp – to execute malicious code directly in the memory. This approach deviates from the typical sequential execution flow seen in widespread ransomware types, enhancing its stealth capabilities." Kaspersky said it observed the ransomware used in a cyber attack targeting an unnamed organization in Colombia, with the threat actors previously delivering the RustyStealer malware to gather corporate credentials. It's believed that the stolen credentials were used to gain unauthorized access to the company's n...
Inside Iran’s Cyber Playbook: AI, Fake Hosting, and Psychological Warfare

Inside Iran's Cyber Playbook: AI, Fake Hosting, and Psychological Warfare

Nov 01, 2024 Cyber Warfare / Hacktivism
U.S. and Israeli cybersecurity agencies have published a new advisory attributing an Iranian cyber group to targeting the 2024 Summer Olympics and compromising a French commercial dynamic display provider to show messages denouncing Israel's participation in the sporting event. The activity has been pinned on an entity that's known as Emennet Pasargad , which the agencies said has been operating under the cover name Aria Sepehr Ayandehsazan (ASA) since mid-2024. It's tracked by the broader cybersecurity community as Cotton Sandstorm, Haywire Kitten, and Marnanbridge. "The group exhibited new tradecraft in its efforts to conduct cyber-enabled information operations into mid-2024 using a myriad of cover personas, including multiple cyber operations that occurred during and targeting the 2024 Summer Olympics – including the compromise of a French commercial dynamic display provider," according to the advisory . ASA, the U.S. Federal Bureau of Investigation (FBI),...
7 PAM Best Practices to Secure Hybrid and Multi-Cloud Environments

7 PAM Best Practices to Secure Hybrid and Multi-Cloud Environments

Dec 04, 2024Risk Management / Zero Trust
Are you using the cloud or thinking about transitioning? Undoubtedly, multi-cloud and hybrid environments offer numerous benefits for organizations. However, the cloud's flexibility, scalability, and efficiency come with significant risk — an expanded attack surface. The decentralization that comes with utilizing multi-cloud environments can also lead to limited visibility into user activity and poor access management.  Privileged accounts with access to your critical systems and sensitive data are among the most vulnerable elements in cloud setups. When mismanaged, these accounts open the doors to unauthorized access, potential malicious activity, and data breaches. That's why strong privileged access management (PAM) is indispensable. PAM plays an essential role in addressing the security challenges of complex infrastructures by enforcing strict access controls and managing the life cycle of privileged accounts. By employing PAM in hybrid and cloud environments, you're not...
U.S. Charges Two Sudanese Brothers for Record 35,000 DDoS Attacks

U.S. Charges Two Sudanese Brothers for Record 35,000 DDoS Attacks

Oct 17, 2024 Cyber Crime / Hacktivism
Federal prosecutors in the U.S. have charged two Sudanese brothers with running a distributed denial-of-service (DDoS) botnet for hire that conducted a record 35,000 DDoS attacks in a single year, including those that targeted Microsoft's services in June 2023. The attacks, which were facilitated by Anonymous Sudan's "powerful DDoS tool," singled out critical infrastructure, corporate networks, and government agencies in the United States and around the world, the U.S. Department of Justice (DoJ) said. Ahmed Salah Yousif Omer, 22, and Alaa Salah Yusuuf Omer, 27, have been charged with one count of conspiracy to damage protected computers. Ahmed Salah has also been charged with three counts of damaging protected computers. If convicted on all charges, Ahmed Salah faces a statutory maximum sentence of life in federal prison, while Alaa Salah faces a maximum sentence of five years in federal prison. The DDoS tool is said to have been disabled in March 2024, the same...

Cloudflare Thwarts Largest-Ever 3.8 Tbps DDoS Attack Targeting Global Sectors

Cloudflare Thwarts Largest-Ever 3.8 Tbps DDoS Attack Targeting Global Sectors

Oct 04, 2024 DDoS Attack / Botnet
Cloudflare has disclosed that it mitigated a record-breaking distributed denial-of-service (DDoS) attack that peaked at 3.8 terabits per second (Tbps) and lasted 65 seconds. The web infrastructure and security company said it fended off "over one hundred hyper-volumetric L3/4 DDoS attacks throughout last month, with many exceeding 2 billion packets per second (Bpps) and 3 terabits per second (Tbps)." The hyper-volumetric L3/4 DDoS attacks have been ongoing since early September 2024, it noted, adding they targeted multiple customers in the financial services, Internet, and telecommunication industries. The activity has not been attributed to any specific threat actor. The previous record for the largest volumetric DDoS attack hit a peak throughput of 3.47 Tbps in November 2021 , targeting an unnamed Microsoft Azure customer in Asia. The attacks leverage the User Datagram Protocol (UDP) protocol on a fixed port, with the flood of packets originating from Vietnam, Russi...
Hacktivist Group Twelve Targets Russian Entities with Destructive Cyber Attacks

Hacktivist Group Twelve Targets Russian Entities with Destructive Cyber Attacks

Sep 21, 2024 Cyber Warfare / Threat Intelligence
A hacktivist group known as Twelve has been observed using an arsenal of publicly available tools to conduct destructive cyber attacks against Russian targets. "Rather than demand a ransom for decrypting data, Twelve prefers to encrypt victims' data and then destroy their infrastructure with a wiper to prevent recovery," Kaspersky said in a Friday analysis. "The approach is indicative of a desire to cause maximum damage to target organizations without deriving direct financial benefit." The hacking group, believed to have been formed in April 2023 following the onset of the Russo-Ukrainian war, has a track record of mounting cyber attacks that aim to cripple victim networks and disrupt business operations. It has also been observed conducting hack-and-leak operations that exfiltrate sensitive information, which is then shared on its Telegram channel. Kaspersky said Twelve shares infrastructural and tactical overlaps with a ransomware group called DARKSTA...
Malware Attackers Using MacroPack to Deliver Havoc, Brute Ratel, and PhantomCore

Malware Attackers Using MacroPack to Deliver Havoc, Brute Ratel, and PhantomCore

Sep 05, 2024 Cyber Threat / Malware
Threat actors are likely employing a tool designated for red teaming exercises to serve malware, according to new findings from Cisco Talos. The program in question is a payload generation framework called MacroPack , which is used to generate Office documents, Visual Basic scripts, Windows shortcuts, and other formats for penetration testing and social engineering assessments. It was developed by French developer Emeric Nasi. The cybersecurity company said it found artifacts uploaded to VirusTotal from China, Pakistan, Russia, and the U.S. that were all generated by MacroPack and used to deliver various payloads such as Havoc, Brute Ratel , and a new variant of PhantomCore , a remote access trojan (RAT) attributed to a hacktivist group named Head Mare. "A common feature in all the malicious documents we dissected that caught our attention is the existence of four non-malicious VBA subroutines," Talos researcher Vanja Svajcer said . "These subroutines appeared...
Hacktivists Exploits WinRAR Vulnerability in Attacks Against Russia and Belarus

Hacktivists Exploits WinRAR Vulnerability in Attacks Against Russia and Belarus

Sep 03, 2024 Ransomware / Malware
A hacktivist group known as Head Mare has been linked to cyber attacks that exclusively target organizations located in Russia and Belarus. "Head Mare uses more up-to-date methods for obtaining initial access," Kaspersky said in a Monday analysis of the group's tactics and tools. "For instance, the attackers took advantage of the relatively recent CVE-2023-38831 vulnerability in WinRAR, which allows the attacker to execute arbitrary code on the system via a specially prepared archive. This approach allows the group to deliver and disguise the malicious payload more effectively." Head Mare, active since 2023, is one of the hacktivist groups attacking Russian organizations in the context of the Russo-Ukrainian conflict that began a year before. It also maintains a presence on X , where it has leaked sensitive information and internal documentation from victims. Targets of the group's attacks include governments, transportation, energy, manufacturing, ...
Unpacking Slack Hacks: 6 Ways to Protect Sensitive Data with Secure Collaboration

Unpacking Slack Hacks: 6 Ways to Protect Sensitive Data with Secure Collaboration

Aug 26, 2024 Data Security / Compliance
Nowadays, sensitive and critical data is traveling in everyday business channels that offer only the basic level of security and encryption, and companies are often oblivious to the risk. A case in point: Disney suffered a devastating data leak by a hacktivist group known as NullBulge that got hold of over 1.2 terabytes of data from Disney's internal Slack messaging channels. The breach exposed sensitive information, including: details about unreleased projects, computer code, login details and passwords, and Intellectual Property (IP) and corporate secrets. Slack breaches have also impacted companies like Uber, Rockstar, and Electronic Arts (EA). Cisco Webex used by the German Bundeswehr leaked data from hundreds of meetings, some classified. Outlook was breached by Chinese hackers last year. We have nothing against any of the tools above. They are all great collaboration tools. However, just like companies don't allow developers to use just any old tool to push code to p...

Microsoft Outlook Flaw Exploited by Russia's APT28 to Hack Czech, German Entities

May 04, 2024 Cyber Espionage / Network Security
Czechia and Germany on Friday revealed that they were the target of a long-term cyber espionage campaign conducted by the Russia-linked nation-state actor known as  APT28 , drawing condemnation from the European Union (E.U.), the North Atlantic Treaty Organization (NATO), the U.K., and the U.S. The Czech Republic's Ministry of Foreign Affairs (MFA), in a statement, said some unnamed entities in the country have been attacked using a security flaw in Microsoft Outlook that came to light early last year. "Cyber attacks targeting political entities, state institutions and critical infrastructure are not only a threat to national security, but also disrupt the democratic processes on which our free society is based," the MFA  said . The security flaw in question is  CVE-2023-23397 , a now-patched critical privilege escalation bug in Outlook that could allow an adversary to access Net-NTLMv2 hashes and then use them to authenticate themselves by me...
A New Age of Hacktivism

A New Age of Hacktivism

Feb 22, 2024 Hacktivism / Information Warfare
In the past 2 years, we have observed a significant surge in hacktivism activity due to ongoing wars and geopolitical conflicts in various regions. Since the war against Ukraine began, we have witnessed a notable mobilization of non-state and state-backed actors alike, forming new groups or joining existing hacker collectives.  We understand hacktivism as a form of computer hacking that is done to further the goals of political or social  activism 1 . While  activism  describes a normal, non-disruptive use of the Internet in order to support a specific cause (online petitions, fundraising, coordinating activities),  hacktivism  includes operations that use hacking techniques with the intent to disrupt but not to cause serious harm (e.g., data theft, website defacements, redirects, Denial-of-Service attacks). Cyber operations that inherit a willingness or intent to cause harm to physical property, severe economic damage or loss of life would be referred to...
