Cybersecurity researchers have flagged a "critical" security vulnerability in Microsoft's multi-factor authentication (MFA) implementation that allows an attacker to trivially sidestep the protection and gain unauthorized access to a victim's account. "The bypass was simple: it took around an hour to execute, required no user interaction and did not generate any notification or provide the account holder with any indication of trouble," Oasis Security researchers Elad Luz and Tal Hason said in a report shared with The Hacker News. Following responsible disclosure, the issue – codenamed AuthQuake – was addressed by Microsoft in October 2024. While the Windows maker supports various ways to authenticate users via MFA, one method involves entering a six-digit code from an authenticator app after supplying the credentials. Up to 10 consequent failed attempts are permitted for a single session. The vulnerability identified by Oasis, at its core, concerns...

Microsoft closed out its Patch Tuesday updates for 2024 with fixes for a total of 72 security flaws spanning its software portfolio, including one that it said has been exploited in the wild. Of the 72 flaws, 17 are rated Critical, 54 are rated Important, and one is rated Moderate in severity. Thirty-one of the vulnerabilities are remote code execution flaws, and 27 of them allow for the elevation of privileges. This is in addition to 13 vulnerabilities the company has addressed in its Chromium-based Edge browser since the release of last month's security update . In total, Microsoft has resolved as many as 1,088 vulnerabilities in 2024 alone, per Fortra. The vulnerability that Microsoft has acknowledged as having been actively exploited is CVE-2024-49138 (CVSS score: 7.8), a privilege escalation flaw in the Windows Common Log File System (CLFS) Driver. "An attacker who successfully exploited this vulnerability could gain SYSTEM privileges," the company said in an...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

The Russia-linked advanced persistent threat (APT) group known as Turla has been linked to a previously undocumented campaign that involved infiltrating the command-and-control (C2) servers of a Pakistan-based hacking group named Storm-0156 to conduct its own operations since 2022. The activity, first observed in December 2022, is the latest instance of the nation-state adversary "embedding themselves" in another group's malicious operations to further their own objectives and cloud attribution efforts, Lumen Technologies Black Lotus Labs said. "In December 2022, Secret Blizzard initially gained access to a Storm-0156 C2 server and by mid-2023 had expanded their control to a number of C2s associated with the Storm-0156 actor," the company said in a report shared with The Hacker News. By leveraging their access to these servers, Turla has been found to take advantage of the intrusions already orchestrated by Storm-0156 to deploy custom malware families refe...

Cybersecurity researchers are warning about malicious email campaigns leveraging a phishing-as-a-service ( PhaaS ) toolkit called Rockstar 2FA with an aim to steal Microsoft 365 account credentials. "This campaign employs an AitM [adversary-in-the-middle] attack, allowing attackers to intercept user credentials and session cookies, which means that even users with multi-factor authentication (MFA) enabled can still be vulnerable," Trustwave researchers Diana Solomon and John Kevin Adriano said . Rockstar 2FA is assessed to be an updated version of the DadSec (aka Phoenix) phishing kit. Microsoft is tracking the developers and distributors of the Dadsec PhaaS platform under the moniker Storm-1575 . Like its predecessors, the phishing kit is advertised via services like ICQ, Telegram, and Mail.ru under a subscription model for $200 for two weeks (or $350 for a month), allowing cyber criminals with little-to-no technical expertise to mount campaigns at scale. Some of the...

Microsoft has addressed four security flaws impacting its artificial intelligence (AI), cloud, enterprise resource planning, and Partner Center offerings, including one that it said has been exploited in the wild. The vulnerability that has been tagged with an "Exploitation Detected" assessment is CVE-2024-49035 (CVSS score: 8.7), a privilege escalation flaw in partner.microsoft[.]com. "An improper access control vulnerability in partner.microsoft[.]com allows an unauthenticated attacker to elevate privileges over a network," the tech giant said in an advisory released this week. Microsoft credited Gautam Peri, Apoorv Wadhwa, and an anonymous researcher for reporting the flaw, but did not reveal any specifics on how it's being exploited in real-world attacks. Fixes for the shortcomings are being rolled out automatically as part of updates to the online version of Microsoft Power Apps. Also addressed by Redmond are three other vulnerabilities, two of which...

The Russia-aligned threat actor known as RomCom has been linked to the zero-day exploitation of two security flaws, one in Mozilla Firefox and the other in Microsoft Windows, as part of attacks designed to deliver the eponymous backdoor on victim systems. "In a successful attack, if a victim browses a web page containing the exploit, an adversary can run arbitrary code – without any user interaction required (zero click) – which in this case led to the installation of RomCom's backdoor on the victim's computer," ESET said in a report shared with The Hacker News. The vulnerabilities in question are listed below - CVE-2024-9680 (CVSS score: 9.8) - A use-after-free vulnerability in Firefox's Animation component (Patched by Mozilla in October 2024)  CVE-2024-49039 (CVSS score: 8.8) - A privilege escalation vulnerability in Windows Task Scheduler (Patched by Microsoft in November 2024) RomCom , also known as Storm-0978, Tropical Scorpius, UAC-0180, UNC2596, and...

Dive into the evolution of phishing and malware evasion techniques and understand how attackers are using increasingly sophisticated methods to bypass security measures. The Evolution of Phishing Attacks "I really like the saying that 'This is out of scope' said no hacker ever. Whether it's tricks, techniques or technologies, hackers will do anything to evade detection and make sure their attack is successful," says Etay Maor, Chief Security Strategist at Cato Networks and member of Cato CTRL . Phishing attacks have transformed significantly over the years. 15-20 years ago, simple phishing sites were sufficient for capturing the crown jewels of the time - credit card details. Today, attacks and defense methods have become much more sophisticated, as we'll detail below. "This is also the time where the "cat-and-mouse" attack-defense game began," says Tal Darsan, Security Manager and member of Cato CTRL. At the time, a major defense technique against credit card phishing sites inv...

Government agencies and non-governmental organizations in the United States have become the target of a nascent China state threat actor known as Storm-2077. The adversary, believed to be active since at least January 2024, has also conducted cyber attacks against the Defense Industrial Base (DIB), aviation, telecommunications, and financial and legal services across the world, Microsoft said . The activity cluster, the company added, overlaps with a threat group that Recorded Future's Insikt Group is tracking as TAG-100 . Attack chains have involved targeting various internet-facing edge devices using publicly available exploits to gain initial access and drop Cobalt Strike as well as open-source malware such as Pantegana and Spark RAT, the cybersecurity company noted back in July. "Over the past decade, following numerous government indictments and the public disclosure of threat actors' activities, tracking and attributing cyber operations originating from China has b...

The North Korea-linked threat actor known as Sapphire Sleet is estimated to have stolen more than $10 million worth of cryptocurrency as part of social engineering campaigns orchestrated over a six-month period. These findings come from Microsoft, which said that multiple threat activity clusters with ties to the country have been observed creating fake profiles on LinkedIn, posing as both recruiters and job seekers to generate illicit revenue for the sanction-hit nation. Sapphire Sleet, which is known to be active since at least 2020, overlaps with hacking groups tracked as APT38 and BlueNoroff. In November 2023, the tech giant revealed that the threat actor had established infrastructure that impersonated skills assessment portals to carry out its social engineering campaigns. One of the main methods adopted by the group for over a year is to pose as a venture capitalist, deceptively claiming an interest in a target user's company in order to set up an online meeting. Targ...

Meta Platforms, Microsoft, and the U.S. Department of Justice (DoJ) have announced independent actions to tackle cybercrime and disrupt services that enable scams, fraud, and phishing attacks. To that end, Microsoft's Digital Crimes Unit (DCU) said it seized 240 fraudulent websites associated with an Egypt-based cybercrime facilitator named Abanoub Nady (aka MRxC0DER and mrxc0derii), who advertised for sale a phishing kit called ONNX. Nady's criminal operation is said to date as far back as 2017. "Numerous cybercriminal and online threat actors purchased these kits and used them in widespread phishing campaigns to bypass additional security measures and break into Microsoft customer accounts," Microsoft DCU's Steven Masada said . "While all sectors are at risk, the financial services industry has been heavily targeted given the sensitive data and transactions they handle. In these instances, a successful phish can have devastating real-world consequences...

Microsoft has announced a new Windows Resiliency Initiative as a way to improve security and reliability, as well as ensure that system integrity is not compromised. The idea, the tech giant said, is to avoid incidents like that of CrowdStrike's earlier this July, enable more apps and users to be run without admin privileges, add controls surrounding the use of unsafe apps and drivers, and offer options to encrypt personal data. One of the most important features is Quick Machine Recovery that's expected to be available to the Windows Insider Program community in early 2025. "This feature will enable IT administrators to execute targeted fixes from Windows Update on PCs, even when machines are unable to boot, without needing physical access to the PC," David Weston, vice president of enterprise and OS security at Microsoft, said . "This remote recovery will unblock your employees from broad issues much faster than what has been possible in the past." ...

A newly patched security flaw impacting Windows NT LAN Manager (NTLM) was exploited as a zero-day by a suspected Russia-linked actor as part of cyber attacks targeting Ukraine. The vulnerability in question, CVE-2024-43451 (CVSS score: 6.5), refers to an NTLM hash disclosure spoofing vulnerability that could be exploited to steal a user's NTLMv2 hash. It was patched by Microsoft earlier this week. "Minimal interaction with a malicious file by a user such as selecting (single-click), inspecting (right-click), or performing an action other than opening or executing could trigger this vulnerability," Microsoft revealed in its advisory. Israeli cybersecurity company ClearSky, which discovered the zero-day exploitation of the flaw in June 2024, said it's been abused as part of an attack chain that delivers the open-source Spark RAT malware. "The vulnerability activates URL files, leading to malicious activity," the company said, adding the malicious file...
