Hacking thoughts - Insecure ATM port
Warning: These are just random thoughts and with lot of presumptions; readers are advised that trying/doing similar activity would be a serious criminal offense and finally I am not a native speaker of English and may have used colloquial words hence no arguments on English usage.
I used an ATM today; this machine of a major Indian private bank was located on the premise of its branch. As I finished and turned to exit I noticed network patch cords connected to the ATM NIC were exposed; it shouldn’t be like this … someone could a) Take a picture (like I did) and shout at the bank about the lack of cable security
b) Yank out the cord and get the ATM out of order temporarily
c) Rig the I/O (network socket) by connecting a HUB & AP (power socket was inches away) and hack into the bank network Third is serious stuff, I wondered how one could accomplish this task? here is a possible way...Requirements:
- HUB & Pocket wireless AP, Laptop…
- Tools (NMAP, Cain and Abel, Wireshark,…)
- A quiet day, companion, crutches,…
1) Select a Sunday night
a) Not much of traffic b) Detection may happen only well into business hours on Monday.
2) Get into the ATM with a companion on crutches
He needs help and this takes care of the security guard.
3) Let the companion use the ATM (just fiddling around like operating) meanwhile do something like dropping papers on the floor and under the pretext of gathering them up; quickly connect the equipment (HUB, AP & power) move something inconspicuous like wastepaper bin (there is usually one) to hide them from normal view.
This takes care of the camera (you are out of the view and just picking up some papers) and the casual glance of anyone (wastepaper bin blocks the gear)
4) Sit in a parked car within range of the AP (I saw a good quiet lane across the road), and…
Idea of this post is just to look at the possibility hence kept simple; but this requires lot of skill (which I don’t have :-) ) and may turn out to be taken as FUD phenomenon. I plan to inform the bank about this weakness let me see how they view it.

Automated tool assisted vulnerability assessments
ISO27001 requirements 15.2.2: Technical compliance checking Control states - "Information systems shall be regularly checked for compliance with security implementation standards"
Code of practice ISO27002 states "Technical compliance checking should be performed either manually (supported by appropriate software tools, if necessary) by an experienced system engineer, and/or with the assistance of automated tools, which generate a technical report for subsequent interpretation by a technical specialist"
ISO27k certified companies need to conduct periodic vulnerability assessment and hence employ consultants for this. Mostly the scope is to run a series of predominantly automated tests using vulnerability scanners and provide a report & recommendations.
This makes them comply but Is this enough? NO
This post was triggered by thoughts after
> Reading Information Escapology, part five – Careful with That Proxy, Eugene... Will a standard vulnerability assessment address this? i guess no. It depends on who is doing? depth? methodology? etc.
> After hearing this from a consultant (someone i trust). It seems after a capability presentation session to a large company, the company's CISO asked him if they were the Authorized Scanning Vendor for the scanning tools & was the consulting company PCI DSS compliant... these were the only questions he had on the vulnerability assessment service process; nothing on things like what is the typical approach, methodology, depth, etc. Is it enough if your consultant is an ASV for a tool? Do you need to be PCI DSS compliant to do a vulnerability scan?
Conclusion: For most of them it looks like only compliance matters (or) they want a testing service that is so cookie cutter that the scope will be automatically limited to the basic scan-and-patch kind of findings

CISO and/with IT roles; few thoughts...
(a) The CISO should be seen as a strategic role.
(b) He must be at a leadership level.
(c) The CISO should be independent of IT
(d) He should report to a very senior person in the organization, who has strong hold within the organization”
While the points above are good in general; I believe point “c” is too idealistic and actually depends on the organization dynamics. The IT & CISO roles can conflict in certain scenarios but certainly not impossible to manage. “When a CISO becomes independent of IT, he comes out of his shell. According to the CISO of a leading Indian BPO, this widens the CISO's ability to think about security from an organizational perspective than just IT.”
One cannot presume that IT roles (I am talking about leadership roles) will so severely constrain views to the extent of being considered to be in a shell; any experienced IT pro will have the capability to avoid this state. “if a CISO is expected to limit himself only to day-to-day operational tasks, instead of assuming a larger responsibility for enterprise-wide coordination of security and risk management, he will not be able to usher in improvement”
I disagree on this; an organization having a CISO role in the ORG chart will have a reasonably mature management systems where roles are clearly defined. If a person here is doubling up for CISO role he/she will be at a level on which their involvement in the execution of day-to-day operational tasks/transactions will be nil or at the most minimal. Of course I am in agreement with the CISO being responsible for risk management and improvements. I play multiple roles; project management, service delivery, information security, etc… though I face tough conflicting situations regularly they are being managed effectively. Finally it all depends on the organization dynamics no standardizations can be applied. Well… though off-topic this article Let a Hundred Flowers Blossom has made me re-think about standardization. Right now I am thinking about the various standardizations present on our management systems.

DLP is not only the tool...
Lot of IT managers i meet think DLP is just a software that you deploy on the network this results in ineffective controls. SANS critical control 15 has a neat definition of DLP
"The phrase “Data Loss Prevention” (DLP) refers to a comprehensive approach covering people, processes, and systems that identify, monitor, and protect data in use (e.g., endpoint actions), data in motion (e.g., network actions), and data at rest (e.g., data storage) through deep content inspection and with a centralized management framework."

Few thoughts and links from the past few days (July 25 –27)
Remote IT support tool hijacks customer web server:
Couple of things I noticed Team viewer (or any remote support tool vendor) shouldn't be doing
a) Monitor http requests without specific disclosure of the details of the feature.
b) Start a web server and show an advertisement without providing any additional/alternate information about the main site being down (I would appreciate if they show a custom message maybe with ad's)
c) Not providing the workaround solution on receipt of the incident.

Exchange 2010 Archiving:
Microsoft Exchange 2010 has enhanced archival features that may reduce .pst management complexities; also Multi Mailbox Search & Legal Hold appear to be interesting features.
A potential downside i can think of is management of the secondary mailbox quota.

I found these points very important for any leader to ask himself…:
When a meeting feels flat and perfunctory, what’s going on? What’s on people minds that they are not saying?
What’s possible now that was not possible last year/month?
Of course others are also valid; see the source article : Ten questions every leader ought to be asking

A Managed network solution for SMB
Being from the frontline IT support i often receive calls from my friends, acquaintances, friends of friends, etc. asking technical advice; the recent one was from a small business owner (a friend of friend). They wanted to get their business ISO27001 certified and hired a consultant. The consultant did a preliminary assessment of their IT including technical areas and provided a report of gaps.
The owner checked around and called me; they were basically looking at a managed network where there were policies, procedures, Management/monitoring, controls like internet browsing restrictions, Firewall/IDS, system/network logs, etc. While the policy, procedures part were handled by the consultant he wanted advise on technical stuff.
And they wanted all these at the lowest possible cost.
About the Infrastructure; a switched network, broadband ISP, 2 servers, 45 desktops, 6 notebooks. All OS were windows, router was basic ISP provided, centrally managed antivirus running in all boxes, MS patches using WSUS, Other software patched manually on monthly basis; in total it was a averagely managed environment.
I said i will revert in a day and gave this list: Firewall = Cisco ASA 5505 Base with security plus bundle, Proxy = Squid, IDS = Snort with Aanval free license, S/NMS = Nagios, SYSLOG – Kiwi (now Solarwinds), Log analysis = Splunk:free version.
All the above are planned to be configured on a Dell Poweredge server running VMware ESXi. The real challenge is in the solution integration; so i also gave them few references (mentioning them here would be promotion) for implementation and management of these.
I shall of course follow-up and update if anything interesting comes up.

IT support friendly features in Windows 7…
Integrated Power shell
Unlike XP and Vista PowerShell 2.0 is built-in. After all systems administration is all about scripting and automation.
AppLocker
Software Restriction Policy is replaced by this. We can create rules to specify which files are allowed to run and unspecified files are not allowed to run by default. There is a log only option called “Audit mode” which allows unspecified apps to run but logs an event (there is an AppLocker event log).
Other features i liked would be Windows XP mode and native support for VHD's.
