Microsoft is calling attention to a Morocco-based cybercrime group dubbed  Storm-0539  that's behind gift card fraud and theft through highly sophisticated email and SMS phishing attacks. "Their primary motivation is to steal gift cards and profit by selling them online at a discounted rate," the company  said  in its latest Cyber Signals report. "We've seen some examples where the threat actor has stolen up to $100,000 a day at certain companies." Storm-0539 was  first spotlighted  by Microsoft in mid-December 2023, linking it to social engineering campaigns ahead of the year-end holiday season to steal victims' credentials and session tokens via adversary-in-the-middle ( AitM ) phishing pages. The gang, also called Atlas Lion and active since at least late 2021, is known to then abuse the initial access to register their own devices to bypass authentication and obtain persistent access, gain elevated privileges, and compromise gift card-related ser...

Intro: Why hack in when you can log in? SaaS applications are the backbone of modern organizations, powering productivity and operational efficiency. But every new app introduces critical security risks through app integrations and multiple users, creating easy access points for threat actors. As a result, SaaS breaches have increased, and according to a May 2024 XM Cyber report, identity and credential misconfigurations caused 80% of security exposures. Subtle signs of a compromise get lost in the noise, and then multi-stage attacks unfold undetected due to siloed solutions. Think of an account takeover in Entra ID, then privilege escalation in GitHub, along with data exfiltration from Slack. Each seems unrelated when viewed in isolation, but in a connected timeline of events, it's a dangerous breach. Wing Security's SaaS platform is a multi-layered solution that combines posture management with real-time identity threat detection and response. This allows organizations to get a ...

Researchers have discovered a new security vulnerability stemming from a design flaw in the IEEE 802.11 Wi-Fi standard that tricks victims into connecting to a less secure wireless network and eavesdrop on their network traffic. The  SSID Confusion attack , tracked as CVE-2023-52424, impacts all operating systems and Wi-Fi clients, including home and mesh networks that are based on WEP, WPA3, 802.11X/EAP, and AMPE protocols. The method "involves downgrading victims to a less secure network by spoofing a trusted network name (SSID) so they can intercept their traffic or carry out further attacks," Top10VPN  said , which collaborated with KU Leuven professor and researcher Mathy Vanhoef. "A successful SSID Confusion attack also causes any VPN with the functionality to auto-disable on trusted networks to turn itself off, leaving the victim's traffic exposed." The issue underpinning the attack is the fact that the Wi-Fi standard does not require the network na...

Researchers have detailed a Virtual Private Network (VPN) bypass technique dubbed  TunnelVision  that allows threat actors to snoop on victim's network traffic by just being on the same local network. The "decloaking"  method  has been assigned the CVE identifier  CVE-2024-3661  (CVSS score: 7.6). It impacts all operating systems that implement a DHCP client and has support for DHCP option 121 routes. At its core, TunnelVision involves the routing of traffic without encryption through a VPN by means of an attacker-configured DHCP server using the  classless static route option 121  to set a route on the VPN user's  routing table . It also stems from the fact the DHCP protocol, by design, does not authenticate such option messages, thus exposing them to manipulation. DHCP is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as ...

Several security vulnerabilities disclosed in Brocade SANnav storage area network (SAN) management application could be exploited to compromise susceptible appliances. The 18 flaws  impact  all versions up to and including 2.3.0, according to independent security researcher Pierre Barre, who discovered and reported them. The issues range from incorrect firewall rules, insecure root access, and Docker misconfigurations to lack of authentication and encryption, thus allowing an attacker to intercept credentials, overwrite arbitrary files, and completely breach the device. Some of the most severe flaws are listed below - CVE-2024-2859  (CVSS score: 8.8) - A vulnerability that could allow an unauthenticated, remote attacker to log in to an affected device using the root account and execute arbitrary commands CVE-2024-29960  (CVSS score: 7.5) - The use of hard-coded SSH keys in the OVA image, which could be exploited by an attacker ...

A new malware campaign has been exploiting the updating mechanism of the eScan antivirus software to distribute backdoors and cryptocurrency miners like XMRig through a long-standing threat codenamed GuptiMiner targeting large corporate networks. Cybersecurity firm Avast said the activity is the work of a threat actor with possible connections to a North Korean hacking group dubbed  Kimsuky , which is also known as Black Banshee, Emerald Sleet, and TA427. "GuptiMiner is a highly sophisticated threat that uses an interesting infection chain along with a couple of techniques that include performing DNS requests to the attacker's DNS servers, performing sideloading, extracting payloads from innocent-looking images, signing its payloads with a custom trusted root anchor certification authority, among others," Avast  said . The intricate and elaborate infection chain, at its core, leverages a security shortcoming in the update mechanism of Indian antivi...

When it comes to access security, one recommendation stands out above the rest: multi-factor authentication (MFA). With passwords alone being simple work for hackers, MFA provides an essential layer of protection against breaches. However, it's important to remember that MFA isn't foolproof. It can be bypassed, and it often is.  If a password is compromised, there are several options available to hackers looking to circumvent the added protection of MFA. We'll explore four social engineering tactics hackers successfully use to breach MFA and emphasize the importance of having a strong password as part of a layered defense.  1. Adversary-in-the-middle (AITM) attacks AITM attacks involve deceiving users into believing they're logging into a genuine network, application, or website. But really, they're giving up their information to a fraudulent lookalike. This lets hackers intercept passwords and manipulate security measures, including MFA prompts. For instance, a spear-phis...

A new research has uncovered multiple vulnerabilities that could be exploited to bypass  Windows Hello authentication  on Dell Inspiron 15, Lenovo ThinkPad T14, and Microsoft Surface Pro X laptops. The flaws were discovered by researchers at hardware and software product security and offensive research firm Blackwing Intelligence, who found the weaknesses in the fingerprint sensors from Goodix, Synaptics, and ELAN that are embedded into the devices. A prerequisite for the fingerprint reader exploits is that the users of the targeted laptops have fingerprint authentication already set up. All the three fingerprint sensors are a type of sensor called "match on chip" ( MoC ), which integrates the matching and other biometric management functions directly into the sensor's integrated circuit. "While MoC prevents replaying stored fingerprint data to the host for matching, it does not, in itself, prevent a malicious sensor from spoofing a legitimate sensor's commu...

Malaysian law enforcement authorities have  announced  the takedown of a phishing-as-a-service (PhaaS) operation called  BulletProofLink . The Royal Malaysia Police said the effort, which was carried out with assistance from the Australian Federal Police (AFP) and the U.S. Federal Bureau of Investigation (FBI) on November 6, 2023, was based on information that the threat actors behind the platform were based out of the country. To that end, eight individuals aged between 29 and 56, including the syndicate's mastermind, have been arrested across different locations in Sabah, Selangor, Perak, and Kuala Lumpur, New Straits Times  reported . Along with the arrests, authorities confiscated servers, computers, jewelry, vehicles, and cryptocurrency wallets containing approximately $213,000. BulletProofLink , also called BulletProftLink, is known for offering ready-to-use phishing templates on a subscription basis to other actors for conducting credential harvesting ca...

A new  malvertising campaign  has been found to employ fake sites that masquerade as legitimate Windows news portal to propagate a malicious installer for a popular system profiling tool called CPU-Z. "This incident is a part of a larger malvertising campaign that targets other utilities like Notepad++, Citrix, and VNC Viewer as seen in its infrastructure (domain names) and cloaking templates used to avoid detection," Malwarebytes' Jérôme Segura  said . While malvertising campaigns are known to set up replica sites advertising widely-used software, the latest activity marks a deviation in that the website mimics WindowsReport[.]com. The goal is to trick unsuspecting users searching for CPU-Z on search engines like Google by serving malicious ads that, when clicked, redirect them to the fake portal (workspace-app[.]online). At the same time, users who are not the intended victims of the campaign are served an innocuous blog with different articles, a technique known a...

Senior executives working in U.S.-based organizations are being targeted by a new phishing campaign that leverages a popular adversary-in-the-middle (AiTM) phishing toolkit named  EvilProxy  to conduct credential harvesting and account takeover attacks. Menlo Security said the activity started in July 2023, primarily singling out banking and financial services, insurance, property management and real estate, and manufacturing sectors. "The threat actors leveraged an open redirection vulnerability on the job search platform 'indeed.com,'redirecting victims to malicious phishing pages impersonating Microsoft," security researcher Ravisankar Ramprasad  said  in a report published last week. EvilProxy , first documented by Resecurity in September 2022, functions as a reverse proxy that's set up between the target and a legitimate login page to intercept credentials, two-factor authentication (2FA) codes, and session cookies to hijack accounts of interest. The th...

Microsoft is warning of an increase in adversary-in-the-middle ( AiTM ) phishing techniques, which are being propagated as part of the phishing-as-a-service (PhaaS) cybercrime model. In addition to an uptick in AiTM-capable PhaaS platforms, the tech giant noted that existing phishing services like PerSwaysion are incorporating AiTM capabilities. "This development in the PhaaS ecosystem enables attackers to conduct high-volume phishing campaigns that attempt to circumvent MFA protections at scale," the Microsoft Threat Intelligence team  said  in a series of posts on X (formerly Twitter). Phishing kits with AiTM capabilities work in two ways, one of which concerns the use of reverse proxy servers (i.e., the phishing page) to relay traffic to and from the client and legitimate website and stealthily capture user credentials, two-factor authentication codes, and session cookies. A second method involves synchronous relay servers. "In AiTM through synchronous relay s...

Threat actors are increasingly using a phishing-as-a-service (PhaaS) toolkit dubbed EvilProxy to pull off account takeover attacks aimed at high-ranking executives at prominent companies. According to Proofpoint, an ongoing hybrid campaign has leveraged the service to target thousands of Microsoft 365 user accounts, sending approximately 120,000 phishing emails to hundreds of organizations worldwide between March and June 2023. Nearly 39% of the hundreds of compromised users are said to be C-level executives, including CEOs (9%) and CFOs (17%). The attacks have also singled out personnel with access to financial assets or sensitive information. At least 35% of all compromised users had additional account protections enabled. The campaigns are seen as a response to the increased adoption of multi-factor authentication (MFA) in enterprises, prompting threat actors to evolve their tactics to bypass new security layers by incorporating adversary-in-the-middle ( AitM ) phishing kits to ...

"Dozens" of organizations across the world have been targeted as part of a broad business email compromise ( BEC ) campaign that involved the use of adversary-in-the-middle ( AitM ) techniques to carry out the attacks. "Following a successful phishing attempt, the threat actor gained initial access to one of the victim employee's account and executed an 'adversary-in-the-middle' attack to bypass Office 365 authentication and gain persistence access to that account," Sygnia researchers  said  in a report shared with The Hacker News. "Once gaining persistence, the threat actor exfiltrated data from the compromised account and used his access to spread the phishing attacks against other victim's employees along with several external targeted organizations." The findings come less than a week after Microsoft  detailed  a similar combination of an AitM phishing and a BEC attack aimed at banking and financial services organizations. Sygnia t...

Banking and financial services organizations are the targets of a new multi-stage adversary-in-the-middle ( AitM ) phishing and business email compromise (BEC) attack, Microsoft has revealed. "The attack originated from a compromised trusted vendor and transitioned into a series of AiTM attacks and follow-on BEC activity spanning multiple organizations," the tech giant  disclosed  in a Thursday report. Microsoft, which is tracking the cluster under its emerging moniker  Storm-1167 , called out the group's use of indirect proxy to pull off the attack. This enabled the attackers to flexibly tailor the phishing pages to their targets and carry out session cookie theft, underscoring the continued sophistication of AitM attacks. The modus operandi is unlike other AitM campaigns where the decoy pages act as a  reverse proxy  to harvest credentials and time-based one-time passwords (TOTPs) entered by the victims. "The attacker presented targets with a website th...

The  NuGet  repository is the target of a new "sophisticated and highly-malicious attack" aiming to infect .NET developer systems with cryptocurrency stealer malware. The 13 rogue packages, which were downloaded more than 160,000 times over the past month, have since been taken down. "The packages contained a PowerShell script that would execute upon installation and trigger a download of a 'second stage' payload, which could be remotely executed," JFrog researchers Natan Nehorai and Brian Moussalli  said . While NuGet packages have been in the past found to  contain vulnerabilities  and be abused to  propagate phishing links , the development marks the first-ever discovery of packages with malicious code. Three of the most downloaded packages – Coinbase.Core, Anarchy.Wrapper.Net, and DiscordRichPresence.API – alone accounted for 166,000 downloads, although it's also possible that the threat actors artificially inflated the download counts using bo...
