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

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

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

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

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,

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

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 means of a relay attack. G

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 as  cyberterrorism, 2, 3  Th

Ukraine's biggest telecom operator Kyivstar has  become  the victim of a " powerful hacker attack ," disrupting customer access to mobile and internet services. "The cyberattack on Ukraine's #Kyivstar telecoms operator has impacted all regions of the country with high impact to the capital, metrics show, with knock-on impacts reported to air raid alert network and banking sector as work continues to restore connectivity," NetBlocks  said  in a series of posts on X (formerly Twitter). Kyivstar, which is owned by Dutch-domiciled multinational telecommunication services company VEON,  serves  nearly 25 million mobile subscribers and more than 1 million home internet customers. The company said the attack was "a result of" the war with Russia and that it has notified law enforcement and special state services. While Kyivstar is working to restore the services, the internet watchdog noted that the telco is largely offline. That said, Kyivstar has yet t

The U.S. Department of the Treasury imposed sanctions against a 37-year-old Russian woman for taking part in the laundering of virtual currency for the country's elites and cybercriminal crews, including the Ryuk ransomware group. Ekaterina Zhdanova, per the department, is said to have facilitated large cross border transactions to assist Russian individuals to gain access to Western financial markets and circumvent international sanctions. "Zhdanova utilizes entities that lack Anti-Money Laundering/Combatting the Financing of Terrorism (AML/CFT) controls, such as OFAC-designated Russian cryptocurrency exchange Garantex Europe OU (Garantex)," the treasury department  said  last week.  "Zhdanova relies on multiple methods of value transfer to move funds internationally. This includes the use of cash and leveraging connections to other international money laundering associates and organizations." It's worth noting that Garantex was  previously sanctioned

Cyber criminals and hacktivist groups are increasingly using the Telegram messaging app to coordinate their activities, leak data, and spread disinformation, as the Russia-Ukraine conflict enters its eighth day. A new analysis by Israeli cybersecurity company Check Point Research has  found  that "user volume grew a hundred folds daily on Telegram related groups, peaking at 200,000 per group." Prominent among the groups are anti-Russian cyber attack groups, including the Ukraine government-backed IT Army, which has urged its more 270,000 members to conduct distributed denial-of-service (DDoS) attacks against Russian entities. Other hacktivist-oriented Telegram groups used to coordinate the attacks on Russian targets via DDoS, SMS or call-based attacks are Anna_ and Mark_, Check Point researchers noted. That said, there may be more to these attacks than meets the eye. "It seems that many of the hacktivist groups are more focused on building self-reputation and recei
