Log4Shell ,  ProxyShell ,  ProxyLogon ,  ZeroLogon , and flaws in  Zoho ManageEngine AD SelfService Plus ,  Atlassian Confluence , and  VMware vSphere Client  emerged as some of the top exploited security vulnerabilities in 2021. That's according to a " Top Routinely Exploited Vulnerabilities " report released by cybersecurity authorities from the Five Eyes nations Australia, Canada, New Zealand, the U.K., and the U.S. Other frequently weaponized flaws included a remote code execution bug in Microsoft Exchange Server ( CVE-2020-0688 ), an arbitrary file read vulnerability in Pulse Secure Pulse Connect Secure ( CVE-2019-11510 ), and a path traversal defect in Fortinet FortiOS and FortiProxy ( CVE-2018-13379 ). Nine of the top 15 routinely exploited flaws were remote code execution vulnerabilities, followed by two privilege escalation weaknesses, and one each of security feature bypass, arbitrary code execution, arbitrary file read, and path traver...

Cloudflare on Wednesday disclosed that it acted to mitigate a 15.3 million request-per-second (RPS) distributed denial-of-service (DDoS) attack. The web infrastructure and website security company called it one of the "largest HTTPS DDoS attacks on record."  "HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection," Cloudflare's Omer Yoachimik and Julien Desgats  said . "Therefore it costs the attacker more to launch the attack, and for the victim to mitigate it." The volumetric DDoS attack is said to have lasted less than 15 seconds and targeted an unnamed Cloudflare customer operating a crypto launchpad.  Volumetric DDoS attacks are designed to overwhelm a target network/service with significantly high volumes of malicious traffic, which typically originate from a botnet under a threat actor's control. Cloudflare said the latest attack w...

Network-attached storage (NAS) appliance maker QNAP on Wednesday  said  it's working on updating its QTS and QuTS operating systems after Netatalk last month released patches to contain seven security flaws in its software. Netatalk  is an open-source implementation of the Apple Filing Protocol ( AFP ), allowing Unix-like operating systems to serve as file servers for Apple macOS computers. On March 22, 2022, its maintainers released  version 3.1.13  of the software to resolve major security issues — CVE-2021-31439 ,  CVE-2022-23121 ,  CVE-2022-23122 ,  CVE-2022-23123 ,  CVE-2022-23124 ,  CVE-2022-23125 , and  CVE-2022-0194  — that could be exploited to achieve arbitrary code execution. "This vulnerability [CVE-2022-23121] can be exploited remotely and does not need authentication," NCC Group researchers  noted  last month. "It allows an attacker to get remote code execution as the 'nobody' user on the NAS. This...

Bad actors continuously evolve their tactics and are becoming more sophisticated. Within the past couple of years, we’ve seen supply chain attacks that quickly create widespread damage throughout entire industries. But the attackers aren’t just focusing their efforts on supply chains. For example, businesses are becoming increasingly more reliant on SaaS apps and the cloud – creating a new avenue for attackers to steal critical data and assets. The looming threat of ransomware attacks, phishing scams, and destructive BEC campaigns has businesses wondering: do I need to increase my security? As a result, many managed service providers (MSP) are fielding questions about the level of security they can provide for their customers. In this new environment, MSPs are finding they can no longer avoid offering cybersecurity services. Fortunately,  there’s an eBook  for MSPs who are expanding into the security space as managed security service providers (MSSP).  It’s vital for M...

A China-linked government-sponsored threat actor observed striking European diplomatic entities in March may have been targeting Russian government officials with an updated version of a remote access trojan called  PlugX . Secureworks attributed the attempted intrusions to a threat actor it tracks as Bronze President, and by the wider cybersecurity community under the monikers Mustang Panda, TA416, HoneyMyte, RedDelta, and PKPLUG. "The war in Ukraine has prompted many countries to deploy their cyber capabilities to gain insight about global events, political machinations, and motivations," the cybersecurity firm  said  in a report shared with The Hacker News. "This desire for situational awareness often extends to collecting intelligence from allies and 'friends.'" Bronze President, active since at least July 2018, has a history of conducting espionage operations by leveraging custom and publicly available tools to compromise, maintain long-term access,...

Google on Tuesday officially began rolling out a new "Data safety" section for Android apps on the Play Store to highlight the type of data being collected and shared with third-parties. "Users want to know for what purpose their data is being collected and whether the developer is sharing user data with third parties," Suzanne Frey, Vice President of product for Android security and privacy,  said . "In addition, users want to understand how app developers are securing user data after an app is downloaded." The transparency measure, which is built along the lines of Apple's " Privacy Nutrition Labels ," was  first announced  by Google nearly a year ago in May 2021. The Data safety section, which will show up against every app listing on the digital storefront, presents a unified view of what data is being collected, for what purpose it's being used, and how it's handled, while also highlighting what data is being shared with thi...

The U.S. government on Tuesday  announced  up to $10 million in rewards for information on six hackers associated with the Russian military intelligence service. "These individuals participated in malicious cyber activities on behalf of the Russian government against U.S. critical infrastructure in violation of the Computer Fraud and Abuse Act," the State Department's Rewards for Justice Program  said . All the six Russian officers are members of an advanced persistent threat group called Sandworm (aka Voodoo Bear or Iron Viking), which is known to be operating since at least 2008 with a specific focus on targeting entities in Ukraine with the goal of establishing an illicit, long-term presence in order to mine highly sensitive data. The hackers, who are officers of the Main Intelligence Directorate of the General Staff of the Armed Forces of the Russian Federation ( GRU ), are as follows - Artem Valeryevich Ochichenko , who has been linked to technical reconnaissa...

A "logical flaw" has been disclosed in NPM, the default package manager for the Node.js JavaScript runtime environment, that enables malicious actors to pass off rogue libraries as legitimate and trick unsuspecting developers into installing them. The supply chain threat has been dubbed "Package Planting" by researchers from cloud security firm Aqua. Following responsible disclosure on February 10, the underlying issue was remediated by NPM on April 26. "Up until recently, NPM allowed adding anyone as a maintainer of the package without notifying these users or getting their consent," Aqua's Yakir Kadkoda  said  in a report published Tuesday. This effectively meant that an adversary could create malware-laced packages and assign them to trusted, popular maintainers without their knowledge. The idea here is to add credible owners associated with other popular NPM libraries to the attacker-controlled poisoned package in hopes that doing so would a...

Microsoft on Tuesday disclosed a set of two privilege escalation vulnerabilities in the Linux operating system that could potentially allow threat actors to carry out an array of nefarious activities. Collectively called " Nimbuspwn ," the flaws "can be chained together to gain root privileges on Linux systems, allowing attackers to deploy payloads, like a root backdoor, and perform other malicious actions via arbitrary root code execution," Jonathan Bar Or of the Microsoft 365 Defender Research Team  said  in a report. On top of that, the defects — tracked as  CVE-2022-29799 and CVE-2022-29800  — could also be weaponized as a vector for root access to deploy more sophisticated threats such as ransomware. The vulnerabilities are rooted in a  systemd  component called  networkd-dispatcher , a  daemon program  for the network manager system service that's designed to dispatch network status changes. Specifically, they relate to a combina...

The threat actor behind the prolific Emotet botnet is testing new attack methods on a small scale before co-opting them into their larger volume malspam campaigns, potentially in response to Microsoft's move to disable Visual Basic for Applications (VBA) macros by default across its products. Calling the new activity a "departure" from the group's typical behavior, Proofpoint alternatively  raised the possibility  that the latest set of phishing emails distributing the malware show that the operators are now "engaged in more selective and limited attacks in parallel to the typical massive scale email campaigns." Emotet, the handiwork of a cybercrime group tracked as  TA542  (aka Mummy Spider or  Gold Crestwood ), staged a  revival of sorts  late last year after a 10-month-long hiatus following a coordinated law enforcement operation to take down its attack infrastructure. Since then, Emotet  campaigns  have targeted thousands of custome...

The infamous ransomware group known as Conti has  continued  its onslaught against entities despite suffering a massive data leak of its own earlier this year, according to new research. Conti, attributed to a Russia-based threat actor known as Gold Ulrick , is the second most prevalent malware strain in the ransomware landscape, accounting for  19% of all attacks  during the three-month-period between October and December 2021. One of the most prolific ransomware groups of the last year along the likes of LockBit 2.0, PYSA, and Hive, Conti has locked the networks of hospitals, businesses, and government agencies, while receiving a ransom payment in exchange for sharing the decryption key as part of its name-and-shame scheme. But after the cybercriminal cartel came out in support of Russia over its invasion of Ukraine in February, an anonymous Ukrainian security researcher under the Twitter handle  ContiLeaks  began leaking the source code as well as pr...

A state-backed threat actor with ties to the Democratic People's Republic of Korea (DRPK) has been attributed to a spear-phishing campaign targeting journalists covering the country with the ultimate goal of deploying a backdoor on infected Windows systems. The intrusions, said to be the work of Ricochet Chollima, resulted in the deployment of a novel malware strain called GOLDBACKDOOR, an artifact that shares technical overlaps with another malware named BLUELIGHT, which has been previously linked to the group. "Journalists are high-value targets for hostile governments," cybersecurity firm Stairwell  said  in a report published last week. "Compromising a journalist can provide access to highly-sensitive information and enable additional attacks against their sources." Ricochet Chollima, also known as  APT37 , InkySquid, and ScarCruft, is a North Korean-nexus targeted intrusion adversary that has been involved in espionage attacks since at least 2016. The ...

An Iranian-linked threat actor known as  Rocket Kitten  has been observed actively exploiting a recently patched VMware vulnerability to gain initial access and deploy the Core Impact penetration testing tool on vulnerable systems. Tracked as  CVE-2022-22954  (CVSS score: 9.8), the critical issue concerns a case of remote code execution (RCE) vulnerability affecting VMware Workspace ONE Access and Identity Manager. While the issue was patched by the virtualization services provider on April 6, 2022, the company  cautioned users  of confirmed exploitation of the flaw occurring in the wild a week later. "A malicious actor exploiting this RCE vulnerability potentially gains an unlimited attack surface," researchers from Morphisec Labs  said  in a new report. "This means highest privileged access into any components of the virtualized host and guest environment." Attack chains exploiting the flaw involve the distribution of a PowerShell-based s...

Security researchers have disclosed a security issue that could have allowed attackers to weaponize the VirusTotal platform as a conduit to achieve remote code execution (RCE) on unpatched third-party sandboxing machines employed antivirus engines. The flaw, now patched, made it possible to "execute commands remotely within [through] VirusTotal platform and gain access to its various scans capabilities," Cysource researchers Shai Alfasi and Marlon Fabiano da Silva said in a report exclusively shared with The Hacker News. VirusTotal , part of Google's Chronicle security subsidiary, is a malware-scanning service that analyzes suspicious files and URLs and checks for viruses using more than 70 third-party antivirus products. The attack method involved uploading a DjVu file via the platform's web user interface that when passed to multiple third-party malware scanning engines could trigger an exploit for a high-severity remote code execution flaw in ExifTool , an op...

A security vulnerability has been disclosed in the web version of the Ever Surf wallet that, if successfully weaponized, could allow an attacker to gain full control over a victim's wallet. "By exploiting the vulnerability, it's possible to decrypt the private keys and seed phrases that are stored in the browser's local storage," Israeli cybersecurity company Check Point said in a report shared with The Hacker News. "In other words, attackers could gain full control over the victim's wallets." Ever Surf  is a cryptocurrency wallet for the Everscale (formerly FreeTON) blockchain that also doubles up as a cross-platform messenger and allows users to access decentralized apps as well as send and receive non-fungible tokens (NFTs). It's said to have an  estimated  669,700 accounts across the world. By means of different attack vectors like malicious browser extensions or phishing links, the flaw makes it possible to obtain a wallet's encr...

A new variant of an IoT botnet called BotenaGo has emerged in the wild, specifically singling out Lilin security camera DVR devices to infect them with Mirai malware. Dubbed " Lilin Scanner " by Nozomi Networks, the  latest version  is designed to exploit a two-year-old critical  command injection vulnerability  in the DVR firmware that was patched by the Taiwanese company in February 2020. BotenaGo , first documented in November 2021 by AT&T Alien Labs, is written in Golang and features over 30 exploits for known vulnerabilities in web servers, routers and other kinds of IoT devices. The botnet's source code has since been uploaded to GitHub, making it ripe for abuse by other criminal actors. "With only 2,891 lines of code, BotenaGo has the potential to be the starting point for many new variants and new malware families using its source code," the researchers  said  this year. The new BotenaGo malware is the  latest  to exploit vulnera...

The U.S. Federal Bureau of Investigation (FBI) is sounding the alarm on the BlackCat ransomware-as-a-service (RaaS), which it said victimized at least 60 entities worldwide between as of March 2022 since its emergence last November. Also called ALPHV and  Noberus , the malware is notable for being the first-ever ransomware written in the Rust programming language, which is known to be memory safe and offer improved performance. "Many of the developers and money launderers for BlackCat/ALPHV are linked to  DarkSide / BlackMatter , indicating they have extensive networks and experience with ransomware operations," the FBI said in an  advisory  published last week. The disclosure comes weeks after twin reports from  Cisco Talos  and  Kasperksy  uncovered links between BlackCat and BlackMatter ransomware families, including the use of a modified version of a data exfiltration tool dubbed Fendr that's been previously only observed in BlackMatter-r...

Telecom company T-Mobile on Friday confirmed that it was the victim of a security breach in March after the LAPSUS$ mercenary gang managed to gain access to its networks. The acknowledgment came after investigative journalist Brian Krebs  shared  internal chats belonging to the core members of the group indicating that LAPSUS$ breached the company several times in March  prior to the arrest  of its seven members. T-Mobile, in a statement, said that the incident occurred "several weeks ago, with the "bad actor" using stolen credentials to access internal systems. "The systems accessed contained no customer or government information or other similarly sensitive information, and we have no evidence that the intruder was able to obtain anything of value," it added. The VPN credentials for initial access are said to have been obtained from illicit websites like Russian Market with the goal of gaining control of T-Mobile employee accounts, ultimately allowing ...

Atlassian has published a security advisory warning of a critical vulnerability in its Jira software that could be abused by a remote, unauthenticated attacker to circumvent authentication protections. Tracked as  CVE-2022-0540 , the flaw is rated 9.9 out of 10 on the CVSS scoring system and resides in Jira's authentication framework, Jira Seraph. Khoadha of Viettel Cyber Security has been credited with discovering and reporting the security weakness. "A remote, unauthenticated attacker could exploit this by sending a specially crafted HTTP request to bypass authentication and authorization requirements in WebWork actions using an affected configuration," Atlassian  noted . The flaw affects the following Jira products - Jira Core Server, Jira Software Server and Jira Software Data Center: All versions before 8.13.18, 8.14.x, 8.15.x, 8.16.x, 8.17.x, 8.18.x, 8.19.x, 8.20.x before 8.20.6, and 8.21.x Jira Service Management Server and Jira Service Management Data Cent...

A proof-of-concept (PoC) code demonstrating a newly disclosed digital signature bypass vulnerability in Java has been shared online.  The  high-severity flaw  in question,  CVE-2022-21449  (CVSS score: 7.5), impacts the following versions of Java SE and Oracle GraalVM Enterprise Edition - Oracle Java SE: 7u331, 8u321, 11.0.14, 17.0.2, 18 Oracle GraalVM Enterprise Edition: 20.3.5, 21.3.1, 22.0.0.2 The issue resides in Java's implementation of the Elliptic Curve Digital Signature Algorithm ( ECDSA ), a  cryptographic mechanism  to  digitally sign  messages and data for verifying the authenticity and the integrity of the contents. In a nutshell, the cryptographic blunder — dubbed Psychic Signatures in Java — makes it possible to present a totally blank signature, which would still be perceived as valid by the vulnerable implementation. Successful exploitation of the flaw could permit an attacker to forge signatures and bypass authenti...
