The Silent Theft of the Week: Attacks on Pulse Secure Devices
“The security of millions of devices connected to the internet are at risk from malware that has the ability to steal sensitive information or impersonate a computer or device — including the Sony PlayStation 4 and Apple iMac computers — without access to private data. ” “CISA is a collaboration between IT organisations from around the world to improve Internet security and protect the privacy of users. ” CISA warns that “malware capable of stealing sensitive information or impersonating a computer or device without user consent, is becoming increasingly stealthy and is causing serious inconvenience and security risks. ” CISA also adds the following to its advice: “CSA recommends that the industry be vigilant against using unauthorised software from unofficial repositories. Malware can remain active for years, sometimes undetected until users turn off internet connections and anti-malware software. It also can enter the unauthorised software by simply copying the malware onto a piece of malware capable of infecting a device, infecting a browser and sending a malicious link to a malicious website. ” “It also warns that CSA is also concerned by recent cases where compromised devices are used in attack schemes involving espionage. ” “Some of the attacks involved use of unauthorised malware in the form of browser redirections. The malicious code embedded in the redirects could be easily modified and downloaded by an attacker for a more advanced version that enables its complete replacement on target devices. ” CISA concludes “CISA strongly recommends that the industry be vigilant with internet connections and anti-malware software. ” “CISA is also concerned by recent cases where compromised devices were used in attack schemes involving espionage.
Computer Security magazine has a story about this that seems to refer to this article as “The Silent Theft of the Week”. The story is “The Silent Theft of the Week”, but the title is misleading or confusing (which is bad enough) because this article isn’t silent or thefty, it’s the usual kind of article that deals with a vulnerability. The article deals with vulnerabilities that are going to happen anyway as the vulnerabilities are exploitable.
CVE 2019-11510, 2020-8260, 2021-2289 : Attacks on Pulse Secure Devices
The following vulnerabilities affect Pulse Secure Devices, one of the world’s most popular and widely deployed network intrusion detection systems. Each vulnerability can be exploited to execute arbitrary code via the Pulse Secure Device’s operating system and/or applications. The vulnerabilities themselves have been independently and securely exploited by the same group. This article summarizes the vulnerabilities and their consequences. The vulnerabilities have been reviewed by a group of security researchers and by a trusted computer security consultant. The security researchers and consultants do not hold any privileged insight into the exploitation of these flaws.
CVE-2021-22893 and Pulse Secure System Files for Malicious Purposes modified
Scan all downloads of software before execution.
Scan all downloads of software before execution. The software download software is usually accompanied by software source code for creating, compiling, executing and running the software program. If any of the software software source code are altered by mistake before the download is executed, any security problems may occur. In order to solve this problems, we should scan all the downloaded binaries of software.

If any of the software software source code are altered by mistake before the download is executed, any security problems may occur. In order to solve this problems, we should scan all the downloaded binaries of software.
On the local computer, you may use a tool such as IDA, IDA Pro, IDA Pro Lite or any other tool to detect the software that is downloaded as a software package.
On the remote computer, you may use a tool such as a command-line analysis tool such as MSIL. exe or any other utility to analyze the downloading code and detect any security problem.
Use the software package.
Use the command-line analysis.
Use any other program.
Scan all the downloaded binaries of software as a manual method.
If the downloaded software is a binary executable program, you may use the tool provided by Microsoft to scan the downloaded executable file. For example, to scan all the downloaded executables of Microsoft Office, you use the Microsoft Office package and the Microsoft Office.
If the downloaded software is a source code of an application, you can use IDA to scan all the downloaded source code. For example, you need to use IDA to scan all the source code of Microsoft Office or Windows.
If the downloaded software is a source code of an executable program, you can use WinDbg to scan the source code.
Tips of the Day in Computer Security
Just when you think that security is not the biggest problem in the world (for instance, when you’re in your house and you find out that your computer has been hacked and your bank account is under the pump of thieves), the next one pops up.
No, seriously, it just does. It’s just the fact that we have to put some precautions in place.
And in today’s time we have to put them in place just like we had to put them in place before and keep them in place.
We can’t prevent all breaches.
