Early Asacub Trojans steal all text messages and upload them to malicious servers. They receive and execute the following

In the previous article, we will introduce anti-simulation technologies commonly used by malware to readers. In this article, we will introduce various anti-Debugging techniques used by malware to impede reverse engineering, so as to help readers better understand these technologies, this enables more effective dynamic detection and analysis of malware. I. Anti-d

In the current network environment, applications have become the main carrier of the network, and more threats to network security come from the application layer, which puts forward higher requirements for network access control. How to precisely identify users and applications, block applications with security risks, ensure normal use of valid applications, and prevent port theft has become the focus of users on network security. The Web application protection system is also called the website

Recently, we have been talking about the usage of Ubuntu Dash and other different features, but all of them ignore the security. It does not mean that there is no Ubuntu SECURITY Article, but that security is not emphasized as the mainstream. In this article, Matt Hartley, author of Datamation, will describe how to protect Ubuntu security. Linux malware We all think that Linux is invincible, and all Linux versions are not threatened by

Secrets: malware toolbox for poser In the last two years, PoS malware has been widely used due to PoS attacks against Tajikistan, jard.com, and Kmart. With the arrival of the "Black Friday" shopping season, malicious software on the POS machine will certainly be noticed. PoS attackers do not rely solely on their own malware to attack and steal victim data. They w

After all the system security defenses are completed, I am afraid SQL injection, cross-site attacks, and other web Application Layer defenses are left behind. This is also the most troublesome thing for the majority of webmasters, A few days ago, I wrote "Security treasure architecture technology speculation and advanced network security defense" to explain the simplest high-performance defense method, which can be slightly modified based on my own situation, we can deal with most of the attacks

Waf xss bypass posture Due to the wide use of application firewalls, it is necessary to test WAF's ability to defend against xss attacks. Of course, all the experiments are to prove that the vendor must eliminate the vulnerability from the root cause, and cannot lie on the WAF without any worries.Some popular WAF such as F5 Big IP, Imperva Incapsula, AQTRONIX Web

Worrying: a large number of malware emerged after the release of Intel chip vulnerability PoC, worrying about poc Recently, security researchers found that more and more malware samples on the market are trying to develop variants using Intel's previously exposed CPU Security Vulnerabilities (Meltdown and Spectre. According to a survey by experts from many foreign security companies, 119 samples of PoC cod

Vulnerabilities in Cisco FirePower firewalls allow malware Bypass Detection Security Vulnerabilities in CISCO FirePower firewall devices allow malware to bypass the detection mechanism. Cisco is releasing security updates to a critical vulnerability (CVE-2016-1345) that affects FirePower firewall, one of Cisco's latest products. This vulnerability was first discovered by security researchers at Check Poin

In a VDI environment, administrators need to protect organizations against malware, but this process does not include antivirus software that may cause problems. There are no universally accepted standards for malware protection in virtual desktop infrastructure (VDI. Each VDI supplier uses its own method to implement the protection plan. Therefore, there is no clear and detailed tutorial in the VDI environ

Adversarial ROBOT: Build a WAF that combines front and back ends We have introduced some man-in-the-middle attack solutions that combine front and back ends. Due to the particularity of Web programs, the participation of front-end scripts can greatly make up for the shortcomings of the backend, so as to achieve the traditional hard-to-achieve effect. Since the attack can be used for attacks, similar ideas can also be used for defense. If we integra

Shortcuts have recently become a common communication carrier used to spread malware in targeted attacks. Symantec has found many shortcut files used to penetrate the network, as described in previous blog articles. I recently stumbled upon a case where such shortcuts bypass security protection software and successfully fool the recipient to execute malware in the attachment. In this case, the malicious pro
