3rd Oct 2018 – Do you think they are APT 38?

The cyber attack hot topic we focus retail payment system (Fastcash campaign) and adobe product vulnerabilities this week. However an additional cyber security alert announced by DHS. Yes, it is a APT cyber attack activities.
APT processes require a high degree of covertness over a long period of time. If you habit to observe the online real time cyber attack statis map. It looks that cyber attack vector in north korea not in high volume. As far as we know, an APT usually targets either private organizations, states or both for business or political motives. Do you experience below malware actvities?

Can Hijack All Windows Versions
1. Target a legitimate x86 PE (Portable Executable)
2. Create a Windows Registry key with the name same as application he wants to hijack.
3. Provide custom DLL for inject into a legitimate process of application (legitimate x86 PE).
4. Once the custom DLL has been injected, windows OS will be compromised.

Whether we can blame Microsoft fifteen years old undocumented legitimate feature?

2nd Oct 2018 – Homeland security alert (Retail payment system security advisory)

US Homeland security urge banking industry especially payment gateway services provider staying alert of new round of malicious cyber attack of their system. Similar of cyber attack was happened in Taiwan. The heist draw the cash equal to $2.6m (£2.1m). Homeland security reveal how the technique let ATM machine like human vomiting. But this is the bank note. You and me like it.

The key item of this attack is prioritize to compromise the switching application server.  Then malicious applications generate a counterfeit response message using GenerateResponseTransaction1() or GenerateResponseTransaction2() function to response to the acquire with a counterfeit response message and drops the request before the payment switch application processes the message. As a result it fool the issuer with no knowledge of the transaction. Should you have interest of above details, please refer to below URL:


Honeywell Mobile Computers with Android Operating Systems – CVE-2018-14825

Port of Barcelona and Port of San Diego suffers cyber attack on September 2018. The San Diego port indicated the ransomware attack is mainly an administrative problem and the port is open and operating as usual. Cyber attacker conducting cyber attack to logistic industry not new. Honeywell one of the Industrial Control Systems leading manufacturer. They found that a vulnerability occurs in their android mobile computer devices. Since the headline news last week did not mentioned about the vulnerability details. In order to avoid hacker trigger the attack and vendor not going to provide the vulnerabiity details. My observation is that Android has dangerous permission group which allow user to execute in special circumustances.

The details are shown on attach diagram. Should you have interest, please refer to diagram.

Adobe Releases Security Updates – Oct 2018

Many years ago adobe has two main modules Adam and Eve. Now use….. It looks that adobe products hard to manage memory space. So the critical vulnerabilities happens again. It looks that the software patching hit rate in demanding today. It is better to consider virtual patching now.

An attack on media platform causes exposed nearly 50 million user informations – Sep 2018

In 80’s our daily life without any electronic type social media involves. But we understood that we are avoid to talk to the stranger. As time goes by, internet social media fine tune our mind. As a result we make friend and relies on this communication platform.

Since this is a popular open platform. It is hard to avoid scam activities. As a result, the risk factor will growth in such circumstances. Even though you have security awareness . But who can garantee the threat actor only focus to attack the indiviual instead of the social media vendor.

Back in October 2016, the memcached developers fixed three remote code execution vulnerabilities (CVE-2016-8704, CVE-2016-8705 and CVE-2016-8706). The flaws affected memcached’s binary protocol for storing and retrieving data and one of them was in the Simple Authentication and Security Layer (SASL) implementation.

Remark: CVE-2016-8704 – An integer overflow in the process_bin_append_prepend function in Memcached, which is responsible for processing multiple commands of Memcached binary protocol, can be abused to cause heap overflow and lead to remote code execution.

Do you think the data breaches announced by Facebook yesterday whether it happen earlier last year but nobody know?

XSS attack has different ways. For instance XSS callback,…etc

PHP has confirmed the vulnerability and released software updates.


Cisco Releases Security Updates for Multiple Products – September 26, 2018


IOS XE built on Linux and provides a distributed software architecture that moves many operating system responsibilities out of the IOS process and has a copy of IOS running as a separate process.

Since it runs a copy of IOS, all CLI commands are the same between Cisco IOS and IOS XE, in contrast to IOS XR which has a completely different code base and its developers implemented quite a different CLI command set.

IOS XE look like a docker container component.

Cisco has released several updates to address vulnerabilities affecting multiple products. An attacker could exploit some of these vulnerabilities to take control of an affected system.

Cisco IOS and IOS XE Software OSPFv3 Denial of Service Vulnerability(buffer overflow)

The vulnerability is due to incorrect handling of specific OSPFv3 packets. An attacker could exploit this vulnerability by sending crafted OSPFv3 Link-State Advertisements (LSA) to an affected device. An exploit could allow the attacker to cause an affected device to reload, leading to a denial of service (DoS) condition.

Cisco IOS and IOS XE Software SM-1T3/E3 Service Module Denial of Service Vulnerability
Cause the ISR G2 Router or the SM-1T3/E3 module on the ISR4451-X to reload, resulting in a denial of service (DoS) condition on an affected device.

Cisco IOS XE Software NAT Session Initiation Protocol Application Layer Gateway Denial of Service Vulnerability
Improper processing of SIP packets in transit while NAT is performed on an affected device.

Cisco IOS Software Precision Time Protocol Denial of Service Vulnerability
The vulnerability is due to insufficient processing of PTP packets. An attacker could exploit this vulnerability by sending a custom PTP packet to, or through, an affected device.

Cisco IOS and IOS XE Software IPv6 Hop-by-Hop Options Denial of Service Vulnerability
The vulnerability is due to incorrect handling of specific IPv6 hop-by-hop options. An attacker could exploit this vulnerability by sending a malicious IPv6 packet to or through the affected device.

Cisco IOS XE Software Command Injection Vulnerabilities
The vulnerabilities exist because the affected software improperly sanitizes command arguments, failing to prevent access to certain internal data structures on an affected device.

Cisco IOS XE Software Errdisable Denial of Service Vulnerability
The vulnerability is due to a race condition that occurs when the VLAN and port enter an errdisabled state, resulting in an incorrect state in the software. An attacker could exploit this vulnerability by sending frames that trigger the errdisable condition. A successful exploit could allow the attacker to cause the affected device to crash, leading to a DoS condition.

Cisco IOS and IOS XE Software Cluster Management Protocol Denial of Service Vulnerability
The vulnerability is due to improper input validation when handling Cluster Management Protocol (CMP) messages. An attacker could exploit this vulnerability by sending a malicious CMP message to an affected device.

Cisco IOS XE Software Cisco Discovery Protocol Memory Leak Vulnerability
The vulnerability is due to incorrect processing of certain CDP packets. An attacker could exploit this vulnerability by sending certain CDP packets to an affected device.

Cisco Webex Meetings Client for Windows Privilege Escalation Vulnerability
The vulnerability is due to folder permissions that grant a user the permission to read, write, and execute files in the Webex folders. An attacker could exploit this vulnerability to write malicious files to the Webex client directory, affecting all other users of the targeted device. A successful exploit could allow a user to execute commands with elevated privileges.
