FBI Issues Flash Alert on Actively Exploited FatPipe VPN Zero-Day Bug

FBI Issues Flash Alert on Actively Exploited FatPipe VPN Zero-Day Bug

November 19, 2021Ravie Lakshmanan
The U.S. Federal Bureau of Investigation (FBI) has disclosed that an unidentified threat actor has been exploiting a previously unknown weakness in the FatPipe MPVPN networking devices at least since May 2021 to obtain an initial foothold and maintain persistent access into vulnerable networks, making it the latest company to join the likes of Cisco, Fortinet, Citrix, Pulse Secure that have had their systems exploited in the wild. "The vulnerability allowed APT actors to gain access to an unrestricted file upload function to drop a web shell for exploitation activity with root access, leading to elevated privileges and potential follow-on activity," the agency  said  in an alert published this week. "Exploitation of this vulnerability then served as a jumping off point into other infrastructure for the APT actors." In other words, the zero-day vulnerability enables a remote attacker to upload a file to any location on the filesystem on an affected device. The se

A Simple 5-Step Framework to Minimize the Risk of a Data Breach

November 19, 2021The Hacker News
Today's businesses run on data. They collect it from customers at every interaction, and they use it to improve efficiency, increase their agility, and provide higher levels of service. But it's becoming painfully obvious that all of that data businesses collect has also made them an enticing target for cybercriminals. With each passing day, the evidence of that grows. In the last few months, we've witnessed massive data breaches that targeted  Neiman Marcus ,  Facebook , and the  Robinhood  stock trading app. And they're hardly alone. In recent years, the number of data breaches worldwide has averaged  close to three per day . That statistic suggests that the average business has a target on its back and is running out of time to mount a defense of its data. And doing so doesn't have to be difficult. To help, here's a simple 5-step framework businesses of all sizes can use to protect their customer data. Step One: Review and Adapt Data Collection Standards
Experts Expose Secrets of Conti Ransomware Group That Made 25 Million from Victims

Experts Expose Secrets of Conti Ransomware Group That Made 25 Million from Victims

The clearnet and dark web payment portals operated by the  Conti  ransomware group have gone down in what appears to be an attempt to shift to new infrastructure after details about the gang's inner workings and its members were made public. According to  MalwareHunterTeam , "while both the clearweb and Tor domains of the leak site of the Conti ransomware gang is online and working, both their clearweb and Tor domains for the payment site (which is obviously more important than the leak) is down." It's not clear what prompted the shutdown, but the development comes as Swiss cybersecurity firm PRODAFT  offered  an unprecedented look into the group's ransomware-as-a-service (RaaS) model, wherein the developers sell or lease their ransomware technology to affiliates hired from darknet forums, who then carry out attacks on their behalf while also netting about 70% of each ransom payment extorted from the victims. The result? Three members of the Conti team have b
New Side Channel Attacks Re-Enable Serious DNS Cache Poisoning Attacks

New Side Channel Attacks Re-Enable Serious DNS Cache Poisoning Attacks

November 18, 2021Ravie Lakshmanan
Researchers have demonstrated yet another variant of the SAD DNS cache poisoning attack that leaves about 38% of the domain name resolvers vulnerable, enabling attackers to redirect traffic originally destined to legitimate websites to a server under their control. "The  attack  allows an off-path attacker to inject a malicious DNS record into a DNS cache," University of California researchers Keyu Man, Xin'an Zhou, and Zhiyun Qian  said . "SAD DNS attack allows an attacker to redirect any traffic (originally destined to a specific domain) to his own server and then become a man-in-the-middle (MITM) attacker, allowing eavesdropping and tampering of the communication." The latest flaw affects Linux kernels as well as popular DNS software, including BIND, Unbound, and dnsmasq running on top of Linux, but not when run on other operating systems FreeBSD or Windows. From Kaminsky Attack to SAD DNS DNS cache poisoning, also called DNS spoofing, is a  technique  i

Critical Root RCE Bug Affects Multiple Netgear SOHO Router Models

November 18, 2021Ravie Lakshmanan
Networking equipment company Netgear has  released  yet  another round  of  patches  to remediate a high-severity remote code execution vulnerability affecting multiple routers that could be exploited by remote attackers to take control of an affected system. Tracked as  CVE-2021-34991  (CVSS score: 8.8), the pre-authentication buffer overflow flaw in small office and home office (SOHO) routers can lead to code execution with the highest privileges by taking advantage of an issue residing in the Universal Plug and Play ( UPnP ) feature that allows devices to discover each other's presence on the same local network and open ports needed to connect to the public Internet. Because of its ubiquitous nature, UPnP is used by a wide variety of devices, including personal computers, networking equipment, video game consoles and internet of things (IoT) devices. Specifically, the vulnerability stems from the fact that the UPnP daemon accepts unauthenticated HTTP SUBSCRIBE and UNSUBSCRI

How to Build a Security Awareness Training Program that Yields Measurable Results

November 18, 2021The Hacker News
Organizations have been worrying about cyber security since the advent of the technological age. Today, digital transformation coupled with the rise of remote work has made the need for security awareness all the more critical. Cyber security professionals are continuously thinking about how to prevent cyber security breaches from happening, with employees and contractors often proving to be the most significant risk factor for causing cyber security incidents. Proactive cyber security professionals will find that an effective security awareness training program can significantly reduce their risk of getting exposed to a cyber incident. For a security awareness training program to be successful, it must be measurable and yield positive, actionable results over time.  The following looks at what good security awareness looks like and how vital  phishing simulations and awareness training  is in devising effective  cyber security programs.  The essentials of a cyber security awarene
Microsoft Warns about 6 Iranian Hacking Groups Turning to Ransomware

Microsoft Warns about 6 Iranian Hacking Groups Turning to Ransomware

November 17, 2021Ravie Lakshmanan
Nation-state operators with nexus to Iran are increasingly turning to ransomware as a means of generating revenue and intentionally sabotaging their targets, while also engaging in patient and persistent social engineering campaigns and aggressive brute force attacks. No less than six threat actors affiliated with the West Asian country have been discovered deploying ransomware to achieve their strategic objectives, researchers from Microsoft Threat Intelligence Center (MSTIC)  revealed , adding "these ransomware deployments were launched in waves every six to eight weeks on average." Of note is a threat actor tracked as  Phosphorus  (aka Charming Kitten or APT35), which has been found scanning IP addresses on the internet for unpatched Fortinet FortiOS SSL VPN and on-premises Exchange Servers to gain initial access and persistence on vulnerable networks, before moving to deploy additional payloads that enable the actors to pivot to other machines and deploy ransomware.
