Background: The PPP provides small businesses with forgivable loans of up to $10 million per company (8 weeks of payroll). This program was launched on April 3, 2020; it is a forgivable loan program offered primarily to help businesses deal with the adverse consequences COVID- 19.
Point of view: Cybercrooks have been leveraging malicious macros hidden inside XML files to distribute the Dridex financial malware few years ago. But it was happened on 2015. Form my point of view, the incident happen this time have similarity.
Possibility: We can based on below feature and predict that attacker may relies of this feature design weakness to conduct the attack.
Accessing E-TranE-Tran Options •loan data file transfer in XML format (from a software vendor’s product or from a bank’s proprietary system) to the SBA’s E-Tran database •A Web page where lenders can enter loan information on individual loans
Wiki: Session Fixation is an attack that permits an attacker to hijack a valid user session. The attack explores a limitation in the way the web application manages the session ID, more specifically the vulnerable web application.
Comment: I am the eBayer since 2000. However I could not find the official announcement that eBay is going to scan my device. Perhaps I am not the only one has this unsatisfied feeling.
Preface: SmartBear ReadyAPI and SoapUI are automated testing tools that you can use to create functional and security tests for web service APIs. The easiest way to run ReadyAPI tests from Azure DevOps is to use the SoapUI Pro for Azure DevOps task.
Background: The ReadyAPI platform accelerates functional, security and load testing of RESTful, SOAP, GraphQL and other web services right inside the CI/CD pipeline. The DevOps team is no stranger.
Vulnerability details: The security expert found a possible way to conduct cyber attack. When a insider threat occurs. The threat prepatrator can be figure out the target license setup condition. If victim deployed remote floating license setup by ReadyAPI. They will exploit the design weakness for Licensing Server. Since the communications in between SmartAPI and license server is using Java RMI protocol on port 1099 but without transport security. Meanwhile, Java RMI, and the underlying JRMP protocol, relies on Java serialization to transport method arguments, return values and exception data intensively. And therefore the problem is that there’s no way to know what you’re deserializing before you’ve decoded it. So an attacker can serialize a bunch of malicious objects and send them to your application.
Remedy: Allow deserialization, but make it impossible for attackers to create instances of arbitrary classes. For instance: limit the input to a maximum of 10 embedded objects and 50 bytes of input. Besides, the official remedy solution not release yet.
Preface: What if your computer is slow? Perhaps it is a sign of malware infection. This scenario also apply to modern supercomputer. Perhaps it is powerful. So no one aware. This is only a assumption. However modern supercomputer will be infected by malware. Why? Because part of the modern supercomputer has deployed a Linux OS system.
Details: It is true. For instance, Cray has Cluster compatibility mode.It is a standard x86/Linux environment. Several affected labs said that only the login portal to the supercomputer were affected, said Swissinfo.ch. Because hacker will be more interested of scientific research result in this period of time. In this case, how the attacker tried to infect the supercomputer. Please refer to the attached drawing. As usual, the attack entry point is the login portal. But the attacker should infect the client workstation on the beginning phase. For example Cryptocurrency mining malware shell script will be saved as /bin/httpdns. A scheduled task is created to run /bin/httpdns every hour. But it need to take the right time to land the script.
Preface: High-level state-backed APT groups wreak havoc on cyber world. Does this attack only in short time or it will become a constant activities?
Security focus: Information technology professional will relies on DHS (US Homeland security) news update as a standard security alert indicator. For example, I am the follower. Found by tonight that the cyber security main page has changes. To be honest, my observation feedback to me that it is not normal. Regarding to the web page design, it shown that it do not use iFrame. However, the web site layout looks strange. I do not want to use the key term broken to describe. Because of this matter, I just take a look of the header information. It show to me that it is running Drupal.
Anyway it is recommend to remove this disclosure information. Perhaps the method is straight forward. The simplest method is to remove the header in a custom EventSubscriber. Please refer to diagram. The official information shown in follow URL. https://drupal.stackexchange.com/a/201297/47547
The problem now fixed by homeland security – 18th May 2020 – HKT
About the theme: Sound can tell, according to statistic provided by Microsoft. Cyber security attack is rapidly growth especially in education area within past 30 days. Perhaps Healthcare and pharmaceuticals area cyber attack volume not as high as education area. However the details found by Microsoft has similarity with security expert observe in past. There are more and more attacker focus to Linux environment.
Security focus: Backdoor code in the popular Bootstrap. To launch the action, the backdoor must be embedded in a “bootstrap” application (a dropper) that is written in C and called xxx.c. Once compiled and started, the dropper program must infect the first Linux ELF executable that it finds in the current directory. Then, when this newly infected file is executed, your virus code is supposed to run.
The myth said that Linux will be secure than Windows. It will be not correct anymore.
Preface: According to statistical data, most organizations store data in cloud platforms operating in Linux based environment. Statistics show that, compared with the Windows operating system, Linux coverage rate exceeds 75%.
Background: Linux system commonly using drive by downloads on an infected website. For instance you install program on Linux sometimes require specify library file (.so). Perhaps your sense of defensive will be downgrade during software installation because you aim to achieve completed the milestone and therefore unintended let the rootkit implant to you Linux system. The rootkit is considered to be a type of Trojan horse. Many Trojan horses exhibit the characteristics of a rootkit. The main difference is that rootkits actively conceal themselves in a system and also typically provide the hacker with administrator rights.
Kernel mode rootkits (Ring 0)
User mode rootkit (Ring 3)
What can we do now? Actively monitor web applications for unauthorized access, modification, or anomalous activities. But stay alert when you download the library file.
Preface: New Kaiji malware targets IoT devices via SSH brute-force.
Background: Gobot is a framework for robotics, drones, and the Internet of Things (IoT), written in the Go programming language.
Observation: Programmers usually choose Golang for building the communication layer within the IoT system. One of the biggest draws to Go is the fact that a single codebase may be compiled for all of the major operating system platforms.
What is codbase: A codebase is a source code repository or a set of repositories that share a common root. The single codebase for an application is used to produce any number of immutable releases that are destined for different environments.
Facts: So it benefits to attacker when he written a malware.
Prediction in regards to current situation: See attached diagram. My prediction is that hacker will be exploit the design weakness in Go language (Go programs primarily use the YMM registers to implement copying one memory buffer to another). So, the case is under observation.
The things you can do right now: Implement effective passwords on all IoT devices when possible.
Preface: Perhaps my alert late for 3 days, but the specify vulnerability hide himself in webLogic product for few years!
Vulnerability details: Alert users that a previously disclosed Oracle WebLogic Server remote code execution vulnerability (CVE-2020-2883) is being exploited in the wild. You can read the official announcement in following link – https://blogs.oracle.com/security/apply-april-2020-cpu
One of the exploit methods – The attacker can locate all of the objects by packet capture. For more details, please refer to attached diagram for reference. As a result, the attacker can replace these objects with his malicious payload. Since the server receives the data and unpacks (deserializes) without integrity check. And therefore it let attacker execute the malicious code on the underlying WebLogic core, allowing the attacker to take control over unpatched systems.
