The U.S. Department of Justice (DoJ) on Monday unsealed indictments against seven Chinese nationals for their involvement in a hacking group that targeted U.S. and foreign critics, journalists, businesses, and political officials for about 14 years. The defendants include Ni Gaobin (倪高彬), Weng Ming (翁明), Cheng Feng (程锋), Peng Yaowen (彭耀文), Sun Xiaohui (孙小辉), Xiong Wang (熊旺), and Zhao Guangzong (赵光宗).  The suspected cyber spies have been charged with conspiracy to commit computer intrusions and conspiracy to commit wire fraud in connection with a state-sponsored threat group tracked as  APT31 , which is also known as Altaire,  Bronze Vinewood , Judgement Panda, and Violet Typhoon (formerly Zirconium). The hacking collective has been  active since at least 2010 . Specifically, their responsibilities entail testing and exploiting the malware used to conduct the intrusions, managing the attack infrastructure, and conducting surveillance of specific U.S. entities, federal prosecutors no

Minecraft, with over 500 million registered users and 166 million monthly players, faces significant risks from distributed denial-of-service (DDoS) attacks, threatening server functionality, player experience, and the game's reputation. Despite the prevalence of DDoS attacks on the game, the majority of incidents go unreported, leaving a gap in awareness and protection. This article explains what happens to a Minecraft server during a DDoS attack and how to protect against such attacks. For an in-depth version of the article,  check out this white paper . When Creepers Breach: What Happens When an Attack Is Successful When a Minecraft server is hit with a DDoS attack, players may have problems with logging in to servers, loading worlds, navigating biomes, using tools, and chatting. They can also experience general lags, disconnections, timeouts, or server crashes. These in-game disruptions can ruin the gaming experience for players while causing financial and reputational losses to

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) sanctioned three cryptocurrency exchanges for offering services used to evade economic restrictions imposed on Russia following its invasion of Ukraine in early 2022. This includes Bitpapa IC FZC LLC, Crypto Explorer DMCC (AWEX), and Obshchestvo S Ogranichennoy Otvetstvennostyu Tsentr Obrabotki Elektronnykh Platezhey (TOEP). In all, the designations cover thirteen entities and two individuals operating in the Russian financial services and technology sectors. "Many of the individuals and entities designated today facilitated transactions or offered other services that helped OFAC-designated entities evade sanctions," the Treasury  said , adding the action seeks to "target companies servicing Russia's core financial infrastructure and curtail Russia's use of the international financial system to further its war against Ukraine." Bitpapa, which offers virtual currency excha

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday  placed  three security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities added are as follows - CVE-2023-48788  (CVSS score: 9.3) - Fortinet FortiClient EMS SQL Injection Vulnerability CVE-2021-44529  (CVSS score: 9.8) - Ivanti Endpoint Manager Cloud Service Appliance (EPM CSA) Code Injection Vulnerability CVE-2019-7256  (CVSS score: 10.0) - Nice Linear eMerge E3-Series OS Command Injection Vulnerability The shortcoming impacting Fortinet FortiClient EMS  came to light  earlier this month, with the company describing it as a flaw that could allow an unauthenticated attacker to execute unauthorized code or commands via specifically crafted requests. Fortinet has since revised its advisory to confirm that it has been exploited in the wild, although no other details regarding the nature of the attacks are currently available. CVE-20

Unidentified adversaries orchestrated a sophisticated attack campaign that has impacted several individual developers as well as the GitHub organization account associated with Top.gg, a Discord bot discovery site. "The threat actors used multiple TTPs in this attack, including account takeover via stolen browser cookies, contributing malicious code with verified commits, setting up a custom Python mirror, and publishing malicious packages to the PyPI registry," Checkmarx  said  in a technical report shared with The Hacker News. The software supply chain attack is said to have led to the theft of sensitive information, including passwords, credentials, and other valuable data. Some aspects of the campaign were  previously   disclosed  at the start of the month by an Egypt-based developer named Mohammed Dief. It chiefly entailed setting up a clever typosquat of the official PyPI domain known as "files. python hosted[.]org," giving it the name "files. pypi ho

In January 2024, Microsoft discovered they'd been the  victim of a hack  orchestrated by Russian-state hackers Midnight Blizzard (sometimes known as Nobelium). The concerning detail about this case is how easy it was to breach the software giant. It wasn't a highly technical hack that exploited a zero-day vulnerability – the hackers used a simple password spray attack to take control of an old, inactive account. This serves as a stark reminder of the importance of password security and why organizations need to protect every user account.  Password spraying: A simple yet effective attack The hackers gained entry by using a  password spray attack in November 2023 , Password spraying is a relatively simple brute force technique that involves trying the same password against multiple accounts. By bombarding user accounts with known weak and compromised passwords, the attackers were able to gain access to a legacy non-production test account within the Microsoft system which provided th

A new security shortcoming discovered in Apple M-series chips could be exploited to extract secret keys used during cryptographic operations. Dubbed  GoFetch , the vulnerability relates to a microarchitectural side-channel attack that takes advantage of a feature known as data memory-dependent prefetcher (DMP) to target constant-time cryptographic implementations and capture sensitive data from the CPU cache. Apple was made aware of the findings in December 2023. Prefetchers are a hardware optimization technique that predicts what memory addresses a currently running program will access in the near future and retrieve the data into the cache accordingly from the main memory. The goal of this approach is to reduce the program's memory access latency. DMP is a type of prefetcher that takes into account the contents of memory based on previously observed access patterns when determining what to prefetch. This behavior makes it ripe for cache-based attacks that trick the prefetche

The Iran-affiliated threat actor tracked as  MuddyWater  (aka Mango Sandstorm or TA450) has been linked to a new phishing campaign in March 2024 that aims to deliver a legitimate Remote Monitoring and Management (RMM) solution called Atera. The activity, which took place from March 7 through the week of March 11, targeted Israeli entities spanning global manufacturing, technology, and information security sectors, Proofpoint said. "TA450 sent emails with PDF attachments that contained malicious links," the enterprise security firm  said . "While this method is not foreign to TA450, the threat actor has more recently relied on including malicious links directly in email message bodies instead of adding in this extra step." MuddyWater has been attributed to attacks directed against Israeli organizations since late October 2023, with prior findings from Deep Instinct  uncovering  the threat actor's use of another remote administration tool from N-able. This i

The North Korea-linked threat actor known as  Kimsuky  (aka Black Banshee, Emerald Sleet, or Springtail) has been observed shifting its tactics, leveraging Compiled HTML Help (CHM) files as vectors to deliver malware for harvesting sensitive data. Kimsuky, active since at least 2012, is known to target entities located in South Korea as well as North America, Asia, and Europe. According to Rapid7, attack chains have leveraged weaponized Microsoft Office documents, ISO files, and Windows shortcut (LNK) files, with the group also employing CHM files to  deploy malware  on  compromised hosts . The cybersecurity firm has attributed the activity to Kimsuky with moderate confidence, citing similar tradecraft observed in the past. "While originally designed for help documentation, CHM files have also been exploited for malicious purposes, such as distributing malware, because they can execute JavaScript when opened," the company  said . The CHM file is propagated within an IS

German authorities have announced the takedown of an illicit underground marketplace called  Nemesis Market  that peddled narcotics, stolen data, and various cybercrime services. The Federal Criminal Police Office (aka Bundeskriminalamt or BKA) said it seized the digital infrastructure associated with the darknet service located in Germany and Lithuania and confiscated €94,000 ($102,107) in cryptocurrency assets. The operation, conducted in collaboration with law enforcement agencies from Germany, Lithuania, and the U.S., took place on March 20, 2024, following an extensive investigation that commenced in October 2022. Founded in 2021, Nemesis Market is estimated to have had more than 150,000 user accounts and 1,100 seller accounts from all over the world prior to its shutdown. Almost 20$ of the seller accounts were from Germany. "The range of goods available on the marketplace included narcotics, fraudulently obtained data and goods, as well as a selection of cybercrime serv

The WINELOADER backdoor used in recent cyber attacks targeting diplomatic entities with wine-tasting phishing lures has been attributed as the handiwork of a hacking group with links to Russia's Foreign Intelligence Service (SVR), which was responsible for  breaching SolarWinds and Microsoft . The findings come from Mandiant, which said  Midnight Blizzard  (aka APT29, BlueBravo, or Cozy Bear) used the malware to target German political parties with phishing emails bearing a logo from the Christian Democratic Union (CDU) around February 26, 2024. "This is the first time we have seen this APT29 cluster target political parties, indicating a possible area of emerging operational focus beyond the  typical   targeting  of  diplomatic missions ," researchers Luke Jenkins and Dan Black  said . WINELOADER was  first disclosed  by Zscaler ThreatLabz last month as part of a cyber espionage campaign that's believed to have been ongoing since at least July 2023. It attribute

Cybersecurity researchers have detected a new wave of phishing attacks that aim to deliver an ever-evolving information stealer referred to as  StrelaStealer . The campaigns impact more than 100 organizations in the E.U. and the U.S., Palo Alto Networks Unit 42 researchers said in a new report published today. "These campaigns come in the form of spam emails with attachments that eventually launch the StrelaStealer's DLL payload," researchers Benjamin Chang, Goutam Tripathy, Pranay Kumar Chhaparwal, Anmol Maurya, and Vishwa Thothathri said . "In an attempt to evade detection, attackers change the initial email attachment file format from one campaign to the next, to prevent detection from the previously generated signature or patterns." First disclosed in November 2022, StrelaStealer is  equipped  to siphon email login data from well-known email clients and exfiltrate them to an attacker-controlled server. Since then, two large-scale campaigns involving the ma

Cybersecurity researchers have shared details of a now-patched security vulnerability in Amazon Web Services (AWS) Managed Workflows for Apache Airflow ( MWAA ) that could be potentially exploited by a malicious actor to hijack victims' sessions and achieve remote code execution on underlying instances. The vulnerability, now addressed by AWS, has been codenamed  FlowFixation  by Tenable. "Upon taking over the victim's account, the attacker could have performed tasks such as reading connection strings, adding configurations and triggering directed acyclic graphs (DAGS)," senior security researcher Liv Matan  said  in a technical analysis. "Under certain circumstances such actions can result in RCE on the instance that underlies the MWAA, and in lateral movement to other services." The root cause of the vulnerability, per the cybersecurity firm, is a combination of  session fixation  on the web management panel of AWS MWAA and an AWS domain misconfigura

A China-linked threat cluster leveraged security flaws in Connectwise ScreenConnect and F5 BIG-IP software to deliver custom malware capable of delivering additional backdoors on compromised Linux hosts as part of an "aggressive" campaign. Google-owned Mandiant is  tracking  the activity under its uncategorized moniker  UNC5174  (aka Uteus or Uetus), describing it as a "former member of Chinese hacktivist collectives that has since shown indications of acting as a contractor for China's Ministry of State Security (MSS) focused on executing access operations." The threat actor is believed to have orchestrated widespread attacks against Southeast Asian and U.S. research and education institutions, Hong Kong businesses, charities and non-governmental organizations (NGOs), and U.S. and U.K. government organizations between October and November 2023, and again in February 2024 using the ScreenConnect bug. Initial access to target environments is facilitated by t
