A novel hardware attack dubbed  PACMAN  has been demonstrated against Apple's M1 processor chipsets, potentially arming a malicious actor with the capability to gain arbitrary code execution on macOS systems. It leverages "speculative execution attacks to bypass an important memory protection mechanism, ARM Pointer Authentication, a security feature that is used to enforce pointer integrity," MIT researchers Joseph Ravichandran, Weon Taek Na, Jay Lang, and Mengjia Yan  said  in a new paper. What's more concerning is that "while the hardware mechanisms used by PACMAN cannot be patched with software features, memory corruption bugs can be," the researchers added. The vulnerability is rooted in pointer authentication codes ( PACs ), a line of defense introduced in arm64e architecture that aims to detect and secure against unexpected changes to  pointers  — objects that reference an address location in memory. PACs aim to solve a common problem in software

Cybercriminals are impersonating popular crypto platforms such as Binance, Celo, and Trust Wallet with spoofed emails and fake login pages in an attempt to steal login details and deceptively transfer virtual funds. "As cryptocurrency and non-fungible tokens (NFTs) become more mainstream, and capture headlines for their volatility, there is a greater likelihood of more individuals falling victim to fraud attempting to exploit people for digital currencies," Proofpoint  said  in a new report. "The rise and proliferation of cryptocurrency has also provided attackers with a new method of financial extraction." The targeting of sensitive cryptocurrency data by threat actors was recently echoed by the Microsoft 365 Defender Research Team, which warned about the emerging threat of  cryware  wherein private keys, seed phrases, and wallet addresses are plundered with the goal of siphoning virtual currencies by means of fraudulent transfers. The  swift popularity of We

To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning

As many as four zero-day security vulnerabilities have been disclosed in the HID Mercury access controller system that's used widely in healthcare, education, transportation, and government facilities. "The vulnerabilities uncovered allowed us to demonstrate the ability to remotely unlock and lock doors, subvert alarms and undermine logging and notification systems," Trellix security researchers Steve Povolny and Sam Quinn said in a report shared with The Hacker News. The issues, in a nutshell, could be weaponized by a malicious actor to gain full system control, including the ability to manipulate door locks. One of the bugs (CVE-2022-31481) includes an unauthenticated remote execution flaw that's rated 10 out of 10 for severity on the CVSS scoring system. HID Mercury controllers, which feature highly flexible configurations, are utilized by over 20 OEM (original equipment manufacturer) partners to design and deploy a broad range of access control systems, with

Cybersecurity researchers have taken the wraps off what they call a "nearly-impossible-to-detect" Linux malware that could be weaponized to backdoor infected systems. Dubbed  Symbiote  by threat intelligence firms BlackBerry and Intezer, the stealthy malware is so named for its ability to conceal itself within running processes and network traffic and drain a victim's resources like a  parasite . The operators behind Symbiote are believed to have commenced development on the malware in November 2021, with the threat actor predominantly using it to target the financial sector in Latin America, including banks like Banco do Brasil and Caixa, based on the domain names used. "Symbiote's main objective is to capture credentials and to facilitate backdoor access to a victim's machine," researchers Joakim Kennedy and Ismael Valenzuela said in a report shared with The Hacker News. "What makes Symbiote different from other Linux malware is that it infec

A previously undocumented Chinese-speaking advanced persistent threat (APT) actor dubbed  Aoqin Dragon  has been linked to a string of espionage-oriented attacks aimed at government, education, and telecom entities chiefly in Southeast Asia and Australia dating as far back as 2013. "Aoqin Dragon seeks initial access primarily through document exploits and the use of fake removable devices," SentinelOne researcher Joey Chen  said  in a report shared with The Hacker News. "Other techniques the attacker has been observed using include DLL hijacking,  Themida-packed files , and DNS tunneling to evade post-compromise detection." The group is said to have some level of tactical association with another threat actor known as  Naikon  (aka Override Panda), with the campaigns primarily directed against targets in Australia, Cambodia, Hong Kong, Singapore, and Vietnam. Infections chains mounted by Aoqin Dragon have banked on Asia-Pacific political affairs and pornographi

U.S. cybersecurity and intelligence agencies have  warned  about China-based state-sponsored cyber actors leveraging network vulnerabilities to exploit public and private sector organizations since at least 2020. The widespread intrusion campaigns aim to exploit publicly identified security flaws in network devices such as Small Office/Home Office (SOHO) routers and Network Attached Storage (NAS) devices with the goal of gaining deeper access to victim networks. In addition, the actors used these compromised devices as route command-and-control (C2) traffic to break into other targets at scale, the U.S. National Security Agency (NSA), the Cybersecurity and Infrastructure Security Agency (CISA), and the Federal Bureau of Investigation (FBI)  said  in a joint advisory. The perpetrators, besides shifting their tactics in response to public disclosures, are known to employ a mix of open-source and custom tools for reconnaissance and vulnerability scanning as well as to obscure and ble

An illicit online marketplace known as SSNDOB was taken down in operation led by U.S. law enforcement agencies, the Department of Justice (DoJ) announced Tuesday. SSNDOB trafficked in personal information such as names, dates of birth, credit card numbers, and Social Security numbers of about 24 million individuals in the U.S., generating its operators $19 million in sales revenue. The action saw the seizure of several domains associated with the marketplace — ssndob.ws, ssndob.vip, ssndob.club, and blackjob.biz — in cooperation with authorities from Cyprus and Latvia. According to blockchain analytics firm  Chainalysis , SSNDOB's Bitcoin payment processing system has received nearly $22 million worth of Bitcoin across over 100,000 transactions since April 2015. Furthermore, bitcoin transfers to the tune of more than $100,000 have been unearthed between SSNDOB and  Joker's Stash , another darknet market that specialized in stolen credit card information and voluntarily c

The threat cluster dubbed UNC2165, which shares numerous overlaps with a Russia-based cybercrime group known as Evil Corp, has been linked to multiple LockBit ransomware intrusions in what's seen as an attempt by the latter to get around  sanctions  imposed by the U.S. Treasury in December 2019. "These actors have shifted away from using exclusive ransomware variants to LockBit — a well-known ransomware as a service (RaaS) — in their operations, likely to hinder attribution efforts in order to evade sanctions," threat intelligence firm Mandiant  noted  in an analysis last week. Active since 2019, UNC2165 is known to obtain initial access to victim networks via stolen credentials and a JavaScript-based downloader malware called  FakeUpdates  (aka SocGholish), leveraging it to previously deploy  Hades  ransomware. Hades is the work of a financially motivated hacking group named Evil Corp, which is also called by the monikers Gold Drake and Indrik Spider and has been at

Enforcing the "double-extortion" technique aka pay-now-or-get-breached emerged as a head-turner last year.  May 6th, 2022 is a recent example. The State Department said the Conti strain of ransomware was the most costly in terms of payments made by victims as of January . Conti, a ransomware-as-a-service (RaaS) program, is one of the most notorious ransomware groups and has been responsible for infecting hundreds of servers with malware to gain corporate data or digital damage systems, essentially spreading misery to individuals and hospitals, businesses, government agencies and more all over the world. So, how different is a  ransomware attack  like Conti from the infamous "WannaCry" or "NotPetya"? While other Ransomware variants can spread fast and encrypt files within short time frames, Conti ransomware has demonstrated unmatched speed by which it can access victims' systems. Given the recent spate of data breaches, it is extremely challengin

A new wave of phishing campaigns has been observed spreading a previously documented malware called SVCReady . "The malware is notable for the unusual way it is delivered to target PCs — using shellcode hidden in the properties of Microsoft Office documents," Patrick Schläpfer, a threat analyst at HP,  said  in a technical write-up. SVCReady is said to be in its early stage of development, with the authors iteratively updating the malware several times last month. First signs of activity date back to April 22, 2022. Infection chains involve sending Microsoft Word document attachments to targets via email that contain VBA macros to activate the deployment of malicious payloads. But where this campaign stands apart is that instead of employing PowerShell or MSHTA to retrieve next-stage executables from a remote server, the macro runs shellcode stored in the  document properties , which subsequently drops the SVCReady malware. In addition to achieving persistence on the i

Cybersecurity researchers have disclosed  two unpatched security vulnerabilities  in the open-source U-Boot boot loader. The issues, which were uncovered in the  IP defragmentation  algorithm implemented in U-Boot by NCC Group, could be abused to achieve arbitrary out-of-bounds write and denial-of-service (DoS). U-Boot is a  boot loader  used in Linux-based embedded systems such as ChromeOS as well as ebook readers such as Amazon Kindle and Kobo eReader. The issues are summarized below - CVE-2022-30790  (CVSS score: 9.6) - Hole Descriptor overwrite in U-Boot IP packet defragmentation leads to an arbitrary out-of-bounds write primitive. CVE-2022-30552  (CVSS score: 7.1) - Large buffer overflow leads to DoS in U-Boot IP packet defragmentation code It's worth noting that both the flaws are exploitable only from the local network. But doing so can enable an attacker to root the devices and lead to a DoS by crafting a malformed packet. The shortcomings are expected to be addr

Atlassian on Friday rolled out fixes to address a  critical security flaw  affecting its Confluence Server and Data Center products that have come under active exploitation by threat actors to achieve remote code execution. Tracked as  CVE-2022-26134 , the issue is similar to  CVE-2021-26084  — another security flaw the Australian software company patched in August 2021. Both relate to a case of Object-Graph Navigation Language ( OGNL ) injection that could be exploited to achieve arbitrary code execution on a Confluence Server or Data Center instance. The newly discovered shortcoming impacts all supported versions of Confluence Server and Data Center, with every version after 1.3.0 also affected. It's been resolved in the following versions - 7.4.17 7.13.7 7.14.3 7.15.2 7.16.4 7.17.4 7.18.1 According to stats from internet asset discovery platform  Censys , there are about 9,325 services across 8,347 distinct hosts running a vulnerable version of Atlassian Confluenc

GitLab has moved to address a critical security flaw in its service that, if successfully exploited, could result in an account takeover. Tracked as  CVE-2022-1680 , the issue has a CVSS severity score of 9.9 and was discovered internally by the company. The security flaw affects all versions of GitLab Enterprise Edition (EE) starting from 11.10 before 14.9.5, all versions starting from 14.10 before 14.10.4, and all versions starting from 15.0 before 15.0.1. "When group SAML SSO is configured, the SCIM feature (available only on Premium+ subscriptions) may allow any owner of a Premium group to invite arbitrary users through their username and email, then change those users' email addresses via SCIM to an attacker controlled email address and thus — in the absence of 2FA — take over those accounts," GitLab  said . Having achieved this, a malicious actor can also change the display name and username of the targeted account, the DevOps platform provider cautioned in its

The Parrot traffic direction system (TDS) that came to light earlier this year has had a larger impact than previously thought, according to new research. Sucuri, which has been tracking the same campaign since February 2019 under the name "NDSW/NDSX," said that "the malware was one of the top infections" detected in 2021, accounting for more than 61,000 websites. Parrot TDS was  documented  in April 2022 by Czech cybersecurity company Avast, noting that the PHP script had ensnared web servers hosting more than 16,500 websites to act as a gateway for further attack campaigns. This involves appending a piece of malicious code to all JavaScript files on compromised web servers hosting content management systems (CMS) such as WordPress that are in turn said to be breached by taking advantage of weak login credentials and vulnerable plugins. Besides using different obfuscation tactics to conceal the code, the "injected JavaScript may also be found well indent

An analysis of  leaked chats  from the notorious  Conti ransomware group  earlier this year has revealed that the syndicate has been working on a set of firmware attack techniques that could offer a path to accessing privileged code on compromised devices. "Control over firmware gives attackers virtually unmatched powers both to directly cause damage and to enable other long-term strategic goals," firmware and hardware security firm Eclypsium  said  in a report shared with The Hacker News. "Such level of access would allow an adversary to cause irreparable damage to a system or to establish ongoing persistence that is virtually invisible to the operating system." Specifically, this includes attacks aimed at embedded microcontrollers such as the Intel  Management Engine  ( ME ), a privileged component that's part of the company's processor chipsets and which can completely bypass the operating system. It's worth noting that the reason for this evolv

As ransomware infections have evolved from purely encrypting data to schemes such as double and triple extortion, a new attack vector is likely to set the stage for future campaigns. Called Ransomware for IoT or  R4IoT  by Forescout, it's a "novel, proof-of-concept ransomware that exploits an IoT device to gain access and move laterally in an IT [information technology] network and impact the OT [operational technology] network." This potential pivot is based on the rapid growth in the number of IoT devices as well as the convergence of IT and OT networks in organizations. The ultimate goal of R4IoT is to leverage exposed and vulnerable IoT devices such as IP cameras to gain an initial foothold, followed by deploying ransomware in the IT network and taking advantage of poor operational security practices to hold mission-critical processes hostage. "By compromising IoT, IT, and OT assets, R4IoT goes beyond the usual encryption and data exfiltration to cause phys

A critical security flaw has been uncovered in UNISOC's smartphone chipset that could be potentially weaponized to disrupt a smartphone's radio communications through a malformed packet. "Left unpatched, a hacker or a military unit can leverage such a vulnerability to neutralize communications in a specific location," Israeli cybersecurity company Check Point said in a report shared with The Hacker News. "The vulnerability is in the modem firmware, not in the Android OS itself." UNISOC, a semiconductor company based in Shanghai, is the world's fourth-largest mobile processor manufacturer after Mediatek, Qualcomm, and Apple, accounting for 10% of all SoC shipments in Q3 2021, according to  Counterpoint Research . The now-patched issue has been assigned the identifier CVE-2022-20210 and is rated 9.4 out of 10 for severity on the CVSS vulnerability scoring system. In a nutshell, the vulnerability — discovered following a reverse-engineering of UNISOC

The threat actor known as SideWinder has added a new custom tool to its arsenal of malware that's being used in phishing attacks against Pakistani public and private sector entities. "Phishing links in emails or posts that mimic legitimate notifications and services of government agencies and organizations in Pakistan are primary attack vectors of the gang," Singapore-headquartered cybersecurity company Group-IB  said  in a Wednesday report. SideWinder, also tracked under the monikers Hardcore Nationalist, Rattlesnake, Razor Tiger, and T-APT-04, has been active since at least 2012 with a primary focus on Pakistan and other Central Asian countries like Afghanistan, Bangladesh, Nepal, Singapore, and Sri Lanka. Last month, Kaspersky  attributed  to this group over 1,000 cyber attacks that took place in the past two years, while calling out its persistence and sophisticated obfuscation techniques. The threat actor's modus operandi involves the use of spear-phishing

The U.S. Department of Justice (DoJ) on Wednesday  announced  the seizure of three domains used by cybercriminals to trade stolen personal information and facilitate distributed denial-of-service (DDoS) attacks for hire. This includes weleakinfo[.]to, ipstress[.]in, and ovh-booter[.]com, the first of which allowed its users to traffic hacked personal data and offered a searchable database containing illegally amassed information obtained from over 10,000 data breaches. The database consisted of seven billion indexed records featuring names, email addresses, usernames, phone numbers, and passwords for online accounts that could be accessed through different subscription tiers. The shutdown of weleakinfo[.]to comes more than two years after a related internet domain named weleakinfo[.]com was  confiscated in January 2020 , with law enforcement officials arresting 21 individuals in connection to the operation later that year. Last May, one of its operators was  sentenced  to two year
