The U.S. Department of Justice (DoJ) on Tuesday disclosed that a court-authorized operation allowed the Federal Bureau of Investigation (FBI) to delete PlugX malware from over 4,250 infected computers as part of a "multi-month law enforcement operation." PlugX, also known as Korplug, is a remote access trojan (RAT) widely used by threat actors associated with the People's Republic of China (PRC), allowing for information theft and remote control of compromised devices. An affidavit filed by the FBI noted that the identified PlugX variant is linked to a state-sponsored hacking group called Mustang Panda , which is also referred to as BASIN, Bronze President, Camaro Dragon, Earth Preta, HoneyMyte, RedDelta, Red Lich, Stately Taurus, TA416, and Twill Typhoon. "Since at least 2014, Mustang Panda hackers then infiltrated thousands of computer systems in campaigns targeting U.S. victims, as well as European and Asian governments and businesses, and Chinese dissident...

Microsoft kicked off 2025 with a new set of patches for a total of 161 security vulnerabilities across its software portfolio, including three zero-days that have been actively exploited in attacks. Of the 161 flaws, 11 are rated Critical and 149 are rated Important in severity. One other flaw, a non-Microsoft CVE related to a Windows Secure Boot bypass ( CVE-2024-7344 , CVSS score: 6.7), has not been assigned any severity. According to the Zero Day Initiative , the update marks the largest number of CVEs addressed in a single month since at least 2017. The fixes are in addition to seven vulnerabilities the Windows maker addressed in its Chromium-based Edge browser since the release of December 2024 Patch Tuesday updates. Prominent among the patches released by Microsoft is a trio of flaws in Windows Hyper-V NT Kernel Integration VSP ( CVE-2025-21333 , CVE-2025-21334 , and CVE-2025-21335 , CVSS scores: 7.8) that the company said has come under active exploitation in the wild. ...

Cybersecurity researchers have disclosed multiple security flaws in SimpleHelp remote access software that could lead to information disclosure, privilege escalation, and remote code execution. Horizon3.ai researcher Naveen Sunkavally, in a technical report detailing the findings, said the "vulnerabilities are trivial to reverse and exploit." The list of identified flaws is as follows - CVE-2024-57727 (CVSS score: 7.5) - An unauthenticated path traversal vulnerability that allows an attacker to download arbitrary files from the SimpleHelp server, including the serverconfig.xml file that contains hashed passwords for the SimpleHelpAdmin account and other local technician accounts CVE-2024-57728 (CVSS score: 7.2) - An arbitrary file upload vulnerability that allows an attacker with SimpleHelpAdmin privileges (or as a technician with admin privileges) to upload arbitrary files anywhere on the SimpleServer host, potentially leading to remote code execution CVE-2024-5772...

Microsoft has shed light on a now-patched security flaw impacting Apple macOS that, if successfully exploited, could have allowed an attacker running as "root" to bypass the operating system's System Integrity Protection ( SIP ) and install malicious kernel drivers by loading third-party kernel extensions. The vulnerability in question is CVE-2024-44243 (CVSS score: 5.5), a medium-severity bug that was addressed by Apple as part of macOS Sequoia 15.2 released last month. The iPhone maker described it as a "configuration issue" that could permit a malicious app to modify protected parts of the file system. "Bypassing SIP could lead to serious consequences, such as increasing the potential for attackers and malware authors to successfully install rootkits, create persistent malware, bypass Transparency, Consent and Control (TCC), and expand the attack surface for additional techniques and exploits," Jonathan Bar Or of the Microsoft Threat Intelligen...

New research has pulled back the curtain on a "deficiency" in Google's "Sign in with Google" authentication flow that exploits a quirk in domain ownership to gain access to sensitive data. "Google's OAuth login doesn't protect against someone purchasing a failed startup's domain and using it to re-create email accounts for former employees," Truffle Security co-founder and CEO Dylan Ayrey said in a Monday report.  "And while you can't access old email data, you can use those accounts to log into all the different SaaS products that the organization used." The San Francisco-based company said the issue has the potential to put millions of American users' data at risk simply by purchasing a defunct domain associated with a failed startup and gaining unauthorized access to old employee accounts related to various applications like OpenAI ChatGPT, Slack, Notion, Zoom, and even HR systems. "The most sensitive accou...

What do identity risks, data security risks and third-party risks all have in common? They are all made much worse by SaaS sprawl. Every new SaaS account adds a new identity to secure, a new place where sensitive data can end up, and a new source of third party risk. Learn how you can protect this sprawling attack surface in 2025. What do identity risks, data security risks and third-party risks all have in common? They are all made much worse by SaaS sprawl. Every new SaaS account adds a new identity to secure, a new place where sensitive data can end up, and a new source of third-party risk. And, this growing attack surface, much of which is unknown or unmanaged in most orgs, has become an attractive target for attackers. So, why should you prioritize securing your SaaS attack surface in 2025? Here are 4 reasons. ‍ 1. Modern work runs on SaaS. When's the last time you used something other than a cloud-based app to do your work? Can't remember? You're not alone.  Outside of ...

The Telegram-based online marketplace known as HuiOne Guarantee and its vendors have cumulatively received at least $24 billion in cryptocurrency, dwarfing the now-defunct Hydra to become the largest online illicit marketplace to have ever operated. The figures, released by blockchain analytics firm Elliptic, show that monthly inflows have increased by 51% since July 2024. Huione Guarantee, part of the HuiOne Group of companies, came under spotlight mid-last year when it was exposed as a hub for online fraudsters, advertising money laundering services, stolen data, and even electrified shackles meant for use against people who are trafficked into scam compounds under the pretext of high paying jobs to conduct romance baiting scams . The development led to cryptocurrency company Tether freezing $29.62 million of its stablecoin connected to the marketplace. Established in 2021 ostensibly to facilitate the sale of cars and real estate, it's said to have strong links with Camb...

Threat hunters are calling attention to a new campaign that has targeted Fortinet FortiGate firewall devices with management interfaces exposed on the public internet. "The campaign involved unauthorized administrative logins on management interfaces of firewalls, creation of new accounts, SSL VPN authentication through those accounts, and various other configuration changes," cybersecurity firm Arctic Wolf said in an analysis published last week. The malicious activity is believed to have commenced in mid-November 2024, with unknown threat actors gaining unauthorized access to management interfaces on affected firewalls to alter configurations and extract credentials using DCSync . The exact initial access vector is currently not known, although it has been assessed with "high confidence" that it's likely driven by the exploitation of a zero-day vulnerability given the "compressed timeline across affected organizations as well as firmware versions af...

Russia-linked threat actors have been attributed to an ongoing cyber espionage campaign targeting Kazakhstan as part of the Kremlin's efforts to gather economic and political intelligence in Central Asia. The campaign has been assessed to be the work of an intrusion set dubbed UAC-0063 , which likely shares overlap with APT28, a nation-state group affiliated with Russia's General Staff Main Intelligence Directorate (GRU). It's also known as Blue Athena, BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard, FROZENLAKE, Iron Twilight, ITG05, Pawn Storm, Sednit, Sofacy, and TA422. UAC-0063 was first documented by the Computer Emergency Response Team of Ukraine (CERT-UA) in early 2023, detailing its attacks on government entities using malware families tracked as HATVIBE, CHERRYSPY, and STILLARCH (aka DownEx). It's worth pointing out that the use of these malware strains has been exclusive to this group. Subsequent campaigns have been observed setting their sights o...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a second security flaw impacting BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) products to the Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The vulnerability in question is CVE-2024-12686 (CVSS score: 6.6), a medium-severity bug that could allow an attacker with existing administrative privileges to inject commands and run as a site user. "BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) contain an OS command injection vulnerability that can be exploited by an attacker with existing administrative privileges to upload a malicious file," CISA said. "Successful exploitation of this vulnerability can allow a remote attacker to execute underlying operating system commands within the context of the site user." The addition of CVE-2024-12686 to the KEV catalog comes nearly a month after it a...

A recently disclosed critical security flaw impacting the Aviatrix Controller cloud networking platform has come under active exploitation in the wild to deploy backdoors and cryptocurrency miners. Cloud security firm Wiz said it's currently responding to "multiple incidents" involving the weaponization of CVE-2024-50603 (CVSS score: 10.0), a maximum severity bug that could result in unauthenticated remote code execution. Put differently, a successful exploitation of the flaw could permit an attacker to inject malicious operating system commands owing to the fact that certain API endpoints do not adequately sanitize user-supplied input. The vulnerability has been addressed in versions 7.1.4191 and 7.2.4996. Jakub Korepta, a security researcher at Polish cybersecurity company Securing, has been credited with discovering and reporting the shortcoming. A proof-of-concept (PoC) exploit has since been made publicly available . Data gathered by the cybersecurity company...
