New TunnelVision Attack Allows Hijacking of VPN Traffic via DHCP Manipulation

New TunnelVision Attack Allows Hijacking of VPN Traffic via DHCP Manipulation

May 09, 2024 Encryption / Data Privacy
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 the subnet mask and default gateway 
Kremlin-Backed APT28 Targets Polish Institutions in Large-Scale Malware Campaign

Kremlin-Backed APT28 Targets Polish Institutions in Large-Scale Malware Campaign

May 09, 2024 Mobile Security / Cyber Attack
Polish government institutions have been targeted as part of a large-scale malware campaign orchestrated by a Russia-linked nation-state actor called  APT28 . "The campaign sent emails with content intended to arouse the recipient's interest and persuade him to click on the link," the computer emergency response team, CERT Polska,  said  in a Wednesday bulletin. Clicking on the link redirects the victim to the domain run.mocky[.]io, which, in turn, is used to redirect to another legitimate site named webhook[.]site, a  free service  that allows developers to inspect data that's being sent via a webhook, in an effort to evade detection. The step step involves the download of a ZIP archive file from webhook[.]site, which contains the Windows Calculator binary that masquerades as a JPG image file ("IMG-238279780.jpg.exe"), a hidden batch script file, and another hidden DLL file ("WindowsCodecs.dll"). Should a victim run the application, the malic

Mirai Botnet Exploits Ivanti Connect Secure Flaws for Malicious Payload Delivery

Mirai Botnet Exploits Ivanti Connect Secure Flaws for Malicious Payload Delivery

May 09, 2024 Network Security / Botnet
Two recently disclosed security flaws in Ivanti Connect Secure (ICS) devices are being exploited to deploy the infamous  Mirai botnet . That's according to  findings  from Juniper Threat Labs, which said the vulnerabilities  CVE-2023-46805 and CVE-2024-21887  have been leveraged to deliver the botnet payload. While CVE-2023-46805 is an authentication bypass flaw, CVE-2024-21887 is a command injection vulnerability, thereby allowing an attacker to chain the two into an exploit chain to execute arbitrary code and take over susceptible instances. In the attack chain observed by the network security company, CVE-2023-46805 is exploited to gain access to the "/api/v1/license/key-status/;" endpoint, which is vulnerable to command injection, and inject the payload. As  previously outlined  by Assetnote in their technical deep dive of the CVE-2024-21887, the exploit is triggered by means of a request to "/api/v1/totp/user-backup-code/" to deploy the malware. &quo

Critical F5 Central Manager Vulnerabilities Allow Enable Full Device Takeover

May 09, 2024 Firewall / Network Security
Two security vulnerabilities have been discovered in F5 Next Central Manager that could be exploited by a threat actor to seize control of the devices and create hidden rogue administrator accounts for persistence. The remotely exploitable flaws "can give attackers full administrative control of the device, and subsequently allow attackers to create accounts on any F5 assets managed by the Next Central Manager," security firm Eclypsium  said  in a new report. A description of the two issues is as follows - CVE-2024-21793  (CVSS score: 7.5) - An OData injection vulnerability that could allow an unauthenticated attacker to execute malicious SQL statements through the BIG-IP NEXT Central Manager API CVE-2024-26026  (CVSS score: 7.5) - An SQL injection vulnerability that could allow an unauthenticated attacker to execute malicious SQL statements through the BIG-IP Next Central Manager API Both the flaws impact Next Central Manager versions from 20.0.1 to 20.1.0. The sho

A SaaS Security Challenge: Getting Permissions All in One Place 

May 08, 2024 Attack Surface / SaaS Security
Permissions in SaaS platforms like Salesforce, Workday, and Microsoft 365 are remarkably precise. They spell out exactly which users have access to which data sets. The terminology differs between apps, but each user's base permission is determined by their role, while additional permissions may be granted based on tasks or projects they are involved with. Layered on top of that are custom permissions required by an individual user.  For example, look at a sales rep who is involved in a tiger team investigating churn while also training two new employees. The sales rep's role would grant her one set of permissions to access prospect data, while the tiger team project would grant access to existing customer data. Meanwhile, special permissions are set up, providing the sales rep with visibility into the accounts of the two new employees. While these permissions are precise, however, they are also very complex. Application admins don't have a single screen within these applications th
New Spectre-Style 'Pathfinder' Attack Targets Intel CPU, Leak Encryption Keys and Data

New Spectre-Style 'Pathfinder' Attack Targets Intel CPU, Leak Encryption Keys and Data

May 08, 2024 Data Encryption / Hardware Security
Researchers have discovered two novel attack methods targeting high-performance Intel CPUs that could be exploited to stage a key recovery attack against the Advanced Encryption Standard (AES) algorithm. The techniques have been collectively dubbed  Pathfinder  by a group of academics from the University of California San Diego, Purdue University, UNC Chapel Hill, Georgia Institute of Technology, and Google. "Pathfinder allows attackers to read and manipulate key components of the branch predictor, enabling two main types of attacks: reconstructing program control flow history and launching high-resolution Spectre attacks," Hosein Yavarzadeh, the lead author of the  paper , said in a statement shared with The Hacker News. "This includes extracting secret images from libraries like libjpeg and recovering encryption keys from AES through intermediate value extraction." Spectre is the name given to a  class of side-channel attacks  that exploit  branch prediction
The Fundamentals of Cloud Security Stress Testing

The Fundamentals of Cloud Security Stress Testing

May 08, 2024 Penetration Testing / Cloud Security
״Defenders think in lists, attackers think in graphs," said John Lambert from Microsoft, distilling the fundamental difference in mindset between those who defend IT systems and those who try to compromise them. The traditional approach for defenders is to list security gaps directly related to their assets in the network and eliminate as many as possible, starting with the most critical. Adversaries, in contrast, start with the end goal in mind and focus on charting the path toward a breach. They will generally look for the weakest link in the security chain to break in and progress the attack from there all the way to the crown jewels. Security teams must embrace the attacker's perspective to ensure their organization's cybersecurity defenses are adequate. Drawing an analogy to a daily life example, the standard way to defend our house from intrusion is to ensure all the doors are locked. But to validate that your house is protected requires testing your security like a burgla

Hijack Loader Malware Employs Process Hollowing, UAC Bypass in Latest Version

May 08, 2024 Encryption / Information Stealer
A newer version of a malware loader called  Hijack Loader  has been observed incorporating an updated set of anti-analysis techniques to fly under the radar. "These enhancements aim to increase the malware's stealthiness, thereby remaining undetected for longer periods of time," Zscaler ThreatLabz researcher Muhammed Irfan V A  said  in a technical report. "Hijack Loader now includes modules to add an exclusion for Windows Defender Antivirus, bypass User Account Control (UAC), evade inline API hooking that is often used by security software for detection, and employ process hollowing." Hijack Loader, also called IDAT Loader, is a malware loader that was  first documented  by the cybersecurity company in September 2023. In the intervening months, the tool has been used as a conduit to deliver various malware families. This includes Amadey, Lumma Stealer (aka LummaC2), Meta Stealer, Racoon Stealer V2, Remcos RAT, and Rhadamanthys. What makes the latest vers
