Magento-Based Websites Hacked: Steal Credit Card Data and Install Mining Malware

I keep observe Magento platform so far. On Jan 2018, OnePlus Confirms Credit Card Breach Impacted Up to 40,000 Customers. A security expert found that Oneplus exploiting Magento eCommerce platform. Heard that over 1000 Magenoto stores as hacked this week (Apr 2018). It looks strange that only for 3 months another new cyber security accident happen again. Security experts observed there are three possible ways make the incident happen.

1. Insert malicious code in Magento core files.

2. Attackers deploy cryptojacking scripts that mine Monero on the computers of store visitors.

3. Adobe Flash Player update packages, which would infect users with the AZORult infostealers.

Oil refinery industry security alert! CVE-2018-4841

We heard in frequent that threat actors will be engaged APT attack to hostile country. The more percentage of cyber attack to the important public facilities most likely is the nuclear power facilities and power generator. As we know, a harden procedure has been built by nuclear power facilitates company. In order to avoid the unforeseen cyber incident happens, internet access function is prohibited in that area. However working with SCADA technologies market coverage not limit to nuclear power facilities. The oil refinery industry, natural gas and water supply facilities are relies on SCADA system. Today, a security alert is going to awake oil refinery, gas and water supply industries. Since a announcement by SCADA hardware manufacture Siemens, they inform that their product encountered vulnerability. The manufacture provides the workaround. However, the workaround only suggest to setup a preventive control.  To be honest, may be there are more spaces to do the remediation! Should you aware of this vulnerability. please refer below vendor announcement for reference.

Perhaps a medium vulnerability found on IT product not a shock. However the medium vulnerability co-exists with known critical vulnerabilities created multiple vulnerabilities are unable to foreseen what is the level of damage. Cisco IOS XE fundamental design integrate to open system. The severity of vulnerability CVE-2018-0196 is medium level. End user is allow to disable the http services to avoid the vulnerability. But the default state of the HTTP Server feature is version-dependent. A significant signal alert Cisco customer that corrective control is not enough. A efficient way is enhance your preventive and detective control. That is the implementation of managed security services. The critical vulnerabilities was posted last week. But the vulnerability of CVE-2018-0196 confirmed and therefore it summarized as below:

2018, cyber security incident news highlight, Under our observation

Bank Negara Malaysia (Bank) detected and foiled a cybersecurity incident involving attempted unauthorized fund transfers using falsified SWIFT messages.

3 Comments

Easter holiday make me lazy. Seen cyber incident alert posted by my friend Enoch yesterday. However I just ignore until awaken this evening. The details of this incident was that the crooks use falsified SWIFT Messages try to achieve their goal. The news told that they haven’t successful. As far as I remember, on February this year City Union Bank in India victim of cyber hack through SWIFT system. My speculation is that it is the flaw of MT202. A fundamental design limitation on original MT 202 message. Perhaps MT 202 COV doing the compensated control. But the MT 202 COV must not be used for any other interbank transfer. However MT 202 still valid and not end of life yet. A hints input of technical concerns shown on attach picture see whether this is root causes of this incident.

MT 202 design weakness lure financial crime

i. Suspicious activity monitoring on the underlying originator and beneficiary in the message would not be performed.

ii. The originating bank could be in a jurisdiction with different sanction watch lists and the technical capabilities of each bank’s sanction screening program could vary.

Mar 2018 – Apple Releases Multiple Security Updates

1 Comment

I spend a lot of time to study security update by Apple this week. It looks that core foundation vulnerability bring to my attention. As we know Objective-C is a general-purpose, object-oriented programming language used by Apple for the OS X and iOS operating systems. Retrospectively, vendor has urge developer that a good practices will be prevented memory-related problem. I am concerning about the race condition vulnerability found this time. There are two main kinds of problem that result from incorrect memory management. Freeing or overwriting data that is still in use. Not freeing data that is no longer in use causes memory leaks. This is the way to causes the vulnerability (race condition) happens.

Since there are plenty of vulnerabilities address this time. For more details, please refer to official url for reference.

Drupal core installation can serve as a simple Web site, a single- or multi-user blog, an Internet forum, or a community Web site providing for user-generated content. The risk calculator shown that it is highly critical according NIST Common Misuse Scoring System (NISTIR 7864). Two critical factors told us the following:

  • All data can be modified or deleted
  • All non-public data is accessible

It is indeed nightmare! Drupal user must do the patching immediately. Otherwise there is a new round of data leakage incident will be happened soon!

1 Comment

Hi Folks, homeland security urge computer users stay alert of web browser (FireFox) vulnerability. The design flaw could let the attacker execute a denial-of-service condition.  I review the vulnerability details. It state the following. A use-after-free vulnerability can occur in the compositor during certain graphics operations when a raw pointer is used instead of a reference counted one. This results in a potentially exploitable crash. But I have different imagination of this flaw. In short, please refer below diagram for reference.

To be or not to be? But it is better to conduct the security update now. For more details, please refer below url for reference.

CVE-2017-18225 – See whether does it affect Cisco jabber iPhone and Android client product?

12 Comments

IP telephony integration to IT infrastructure is a main trend in last decade.  Following the security best practice, the IP telephony system should be isolated and far away from data network. However there are end user function requirement which causes unified communications manager integrate with Active directory services. A useful function will be activated after active directory integration. For instance a track record will be shown individual communication history. Meanwhile it will enhance the monitor and control process (SOX 403 monitoring and control). Perhaps a pin does not have two points and therefore it is hard to avoid vulnerability happen. For example, Cisco IP telephone working with Microsoft TSAPI last decade. But most recently Android and iPhone growth rapidly. IP telephony vendor will be make use of open source unintentionally. An XMPP client is any software or application that enables you to connect to an XMPP for instant messaging with other people over the Internet. Cisco official announce that there is a vulnerability found on Jabber client from November 2017 (CVE-2017-12361). 

https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171129-jabber2

The jabber design flaw has been identified this month. The issue is that vulnerability might allow local users to gain privileges by leveraging access to this account and then waiting for root to execute one of these programs. In the meantime, we do not receive announcement release by Cisco (Jabber Security Vulnerabilities CVE-2017-18225). But we keep our eyes open, see whether does it affect Cisco jabber iPhone and Android client product?

Ransomware, Under our observation, Virus & Malware

Threat actor intend to stop your antivirus program – 2018

2 Comments

Just heard that there is a new attack method use by ransomware. The malware intend to stop and disable your workstation antivirus process. Since no antivirus protection, threat actor is free to do their task. Perhaps the defense vendor pay the focus on Ring 0 attack (kernel). Meanwhile new generation AV software implement behavioral detection analysis. So is there any space for threat actor?Yes, the ring 3 looks provides space to threat actor. They may find a way to evade the detection.

For instance:

  1. List all loaded DLL libraries in current process.
  2. Find entry-point address of every imported API function of each DLL library.
  3. Remove the injected hook JMP instruction by replacing it with the API’s original bytes.
