cyber secuirity for hospitals
-BY ADITYA SINGH aditya043k@gmail.com
I choose this topic to write on
because no one knows about how hackers can exploit the hospitals through
cyberattacks in this blog I have tried to cover many topics on how hacker gain
access on medical appliances and machines. I hope that this topic is helpful
for hospital administration.
Gone forever are the days when a patient was treated by a single
physician. Today, a team of physicians and specialized medical technicians rely
on complex medical equipment to diagnose and treat patients. This collaboration
is made possible because electronic medical records (EMRs) securely store large
amounts of medical and clinical information, which is exchanged electronically
among healthcare entities by an industry-specific Medical-Grade Network (MGN).
This medical information is susceptible to being stolen or held for ransom and
malicious hackers can even take direct control of connected active and passive
medical devices over the internet and injure patients. The Health Information
Technology for Economic and Clinical Health (HITECH) Act of 2009 provided
financial incentives for Medicare and Medicaid providers who become “meaningful
users” of EMRs. Among non-federal acute care hospitals, 76 percent were using a
“basic” system by 2014. As of May 2015, more than 468,000 Medicare and Medicaid
providers (87 percent) have received payments through the HITECH Act, totaling
approximately $30.4 billion. as the implementation of the HITECH Act expanded,
so has the cost of data breaches at healthcare facilities in the United States.
Footprinting
Footprinting is how the hacker starts his analysis of the target
hospital network. The hacker sifts through open source material found on the
Internet to learn all he can about the hospital, including who works there,
which equipment is used there, and where the equipment is located. A hacker may
visit the hospital, sniff the wireless spectrum, look in dumpsters, and use
social engineering to assemble a very good picture of the hospital and its
active medical devices to determine where the vulnerabilities are. Once the
hacker knows who manufactured the device that he intends to attack, he finds a
copy of the operating
and maintenance manuals (many are available online). Unfortunately, those
manuals usually reveal the default
password set
at the factory. To make matters worse, some
manufacturers recommend that the healthcare facility keep the default password, because
this makes it easier for the manufacturer’s technician to test the equipment or
perform maintenance. This same glaring vulnerability makes hacking
the
device simple. The hacker launches an account-harvesting
attack to
collect all the user account names on a computer network. Account
harvesting involves using computer programs to search areas on the Internet to
gather lists
of email addresses from a number of sources, including chatrooms, domain names,
instant message
users,
message boards, newsgroups, online directories for web pages belonging to
professional societies, medical web pages, and other online destinations. A
sophisticated hacker uses data
mining to
analyze a vast amount
of information about a target hospital.
Many
hackers resort to social
engineering attacks. Social
engineering is the art and science of getting people
to do something that you want that they might not do in a normal course of
action. In addition to collecting
information by technical means, hackers apply various methods of social
engineerings, such as impersonating
individuals on the telephone or other persuasive means (e.g., tricking,
convincing, inducing,
enticing,
or provoking) to encourage someone to disclose valuable information.
Attackers
look for information about who the target does business with: suppliers and
customers. And they are particularly interested in IT support staff. They
gather this information to better understand staff roles and responsibilities.
They may use this information to pose as someone from one of their suppliers or
vendors. Attackers look for information, such as birthdays, who was recently
promoted, or who just had a
baby.
Hackers do not discount any information that they uncover. They even use bad
relationships between the IT department and other offices as a wedge to gain
information. Attackers send friend requests to hospital staff on Facebook,
Match.com, LinkedIn, and any other Internet sites where people divulge personal
information. Staff should never give away their GPS position, or location
links, or send updates divulging where they will be on vacation. When asked,
instead of saying “I’m going on vacation for two weeks,” I usually say, “I’m
having a staycation and plan to sit at home cleaning my guns.” Hackers often
use behavior-monitoring
hacksThis
involves observing the activities of hospital staff, MGN data traffic, and
processes; and measuring activities against hospital policies and rules,
baselines of normal activity, thresholds, and trends. Hackers have been known
to resort to shoulder
surfing,
or using direct observation techniques, such as looking over a nurse’s shoulder
to obtain personal access information (e.g., passwords, PINs, and security
codes).
The
hacker is not above dumpster
diving to
obtain passwords and the hospital’s directories by searching through discarded
trash bins (also referred to as skipping
).
Eavesdropping is
a low-tech technique that hackers use to listen in to a private conversation to
acquire information that can provide access to an MGN.
A
hacker may go so far as to install a screen
scraper virus
or physical device that logs and captures information sent to a hospital
staffer’s computer display. If a hacker cannot physically visit the hospital,
he could use PlaceRaider to create a virtual layout of the hospital’s interior.
This is a novel Trojan horse visual malware app surreptitiously installed on a
staffer’s smartphone. It allows a hacker to engage in remote reconnaissance to
obtain geolocation data and enlist its accelerometer to create a 3D map of the
phone’s surroundings. A hacker can download images of the physical space, study
the environment, and carefully construct a three-dimensional model of indoor
environments
to survey the staffer’s private home or workplace. PlaceRaider can be used to
photograph virtual objects in the environment, such as financial documents,
information on computer monitors, and personally identifiable patient
information
Scanning
After
hackers research the target hospital using open source websites, such as vendor
marketing materials,
awarded
contracts, medical conference attendee lists, and LinkedIn and Facebook pages,
the hacker
searches
the Shodan database of devices, which are accessible over the Internet. The
Shodan database
allows
a hacker to find IP addresses and begin port scanning to identify which
operating systems the hospital
uses
and then figure out how to access the hospital’s networks. If the target
hospital is accessible by Shodan
(it
should not be), Shodan reveals all services running on the hospital’s computers,
and allows hackers to
Share
this information with others
Other
common network-discovery hacking tools include the Google Hacking Diggity
Project, Nmap, Snort,
Kismet, Nessus, McAfee, Sophia, and Bandolier.
Once
the hacker knows which software applications are running on the target
hospital’s network, he can develop a specific set of tools to exploit known
vulnerabilities. For example, let’s say that the hacker learns that the
building controls system at the target hospital is running Siemens SIMATIC STEP
7 TIA (Portal). In February 2015, Siemens reported two vulnerabilities on that
software. One vulnerability allows a successful,
remote
man-in-the-middle attack. The other allows a hacker with local access to
reconstruct protection level passwords. Although a Siemens software update is
available, it is likely that it hasn’t been installed in many hospitals. A
hacker will probably launch an address
space probe attack when
he finds your hospital networks on
the
Shodan website and locates your IP address space. The hacker is looking for
security holes that might be exploited on the hospital’s network, such as
unpatched vulnerabilities. A hacker uses a passive technique called network sniffing to
monitor hospital network communication, decode protocols, and examine headers
and network traffic for information of interest. It is both a review technique
and target identification and analysis technique. The hacker may launch a probing attack to
attempt to connect to well-known services that may be running on the hospital
network to
see
which operating system exists and potentially identify the version of the software
that it is running. A smart hacker will attempt a few common usernames and
password combinations on several computers, resulting in failed login attempts.
This is called a doorknob-rattling
attack and
can go undetected unless the data
related
to login failures from all the hosts is collected and aggregated to check for
doorknob rattling from any remote destination. If the hacker is really
ambitious, he may resort to emanations
analysis,
or obtaining data by monitoring and resolving electronic signals emitted by
medical equipment that contains the data, but is not designed to communicate
the data.
Programs
that are frequently installed together may be described as parts of the same
spyware package, even if they function separately. The following are some
examples:
•CoolWebSearch (https://en.wikipedia.org/wiki/CoolWebSearch )is a group of
programs that takes advantage of Internet Explorer
vulnerabilities.
The package directs traffic to advertisements on websites, including
CoolWebSearch.com.
It displays pop-up ads, rewrites search engine results, and
alters
the infected computer’s hosts file to direct Domain Name System (DNS)
lookups
to these sites.
Internet
Optimizer,
also known as DyFuCa, redirects Internet Explorer error pages
to
advertising. When users follow a broken link or enter an erroneous URL, they
see
a
page of advertisements. However, because password-protected websites use the
same
mechanism as HTTP errors, Internet Optimizer makes it impossible for the
user
to access password-protected sites.
Network
Mapping
By
this point, the hacker can draw a very detailed layout of the hospital’s
network and visualize the total network environment. The hacker’s network map
is probably more current than your copy because he has found what’s actually
there.
How
Hackers Gain Access to a
Health
care Facility or Hospital
Network
THE MOST COMMON ATTACK THAT A HACKER CAN DO
IS
Email
Phishing AttacK
Email is the preferred method of gaining access to any network
that has Internet access. A hacker will send an email containing active content (carries out or triggers actions automatically without the
intervention of a user), such as a Remote Access Trojan (RAT), to a
hospital employee, such as a biomedical equipment technician (BMET) or a
building maintenance technician. According to a 2015 data breach investigations
report, 23 percent of recipients of phishing emails open them and
11 percent click an attachment. Typically, doctors, nurses, and building
maintenance personnel access their email using the only workstation on their
desk. I recommend that hospitals increase awareness of the importance of not
opening suspicious emails.
TABLE lists some email do’s and don’ts.
DO’S
|
DONT’S
|
Don’t open suspicious emails
|
Don’t use a preview pane for email, use plain text only
|
Don’t click links to websites in any emails
|
Don’t respond to the email that demands that you update
information and gives a link to click.
|
Don’t respond to emails that threaten dire consequences
|
Don’t open the email from strangers.
|
Always look for digital signatures.
|
Scan all attachments.

Appliance
Hacks
A
hacker can gain access to a hospital network through appliance hacks. With
the growth of the Internet of Things, even common appliances such as
dishwashers, coffee makers, clothes dryers, and nursery-room baby monitors
connect to the Internet and could be used as an access and pivot point.
Manufacturers use this capability to troubleshoot the performance of their
equipment, monitor usage, and improve the customer
“
experience .” Unfortunately, knowing when you use the appliance provides data
that could help hackers
learn
your habits and schedule, and geolocate your current position.
Password
Cracker
Hackers
have access to a wide range of tools to decrypt passwords that they find on a
hospital network. The last
resort
is a brute-force attack using
a program such as Zip Password Cracker Pro.
Cyber-Hygiene
Password Tips
Use
a strong password or passphrase. Change the password every 90 days.
Never
use a previous password again. Use lowercase and uppercase letters, numbers,
and special
characters
($, #, ?, %, &, etc.).
Do
not use a common phrase
(123thequickbrownfox,
etc.).
Don’t
write down the password and slip it in the top drawer
of
your desk.
Password
should be at least 14 characters. Don’t give anyone your password— ever
PRACTICAL
TIME
NOW
I WILL SHOW YOU HOW HACKERS GAIN THE ACCESS ON HOSPITALS CCTV CAMERAS
BY EXPLOITING ROUTER {note that:- for this practical your wifi
must have to monitor mode support }
os used:- Kali Linux
- first, you have to download routersploit git package on your system
- commands that you have to enter in the terminal
- cd Desktop/
- git clone https://github.com/threat9/routersploit
- cd rotersploit/
- ls
- pip3 install -r requirements.txt
- ./rsf.py
- show exploits
- show creds

- and open in the browser
- use any user name and password
AND IT’S DONE NOW THE HACKER CAN SEE THE LIVE CCTV RECORDING
IF YOU DON’T BELIEVE IT YOU CAN TRY IT YOURSELF :)
MORAL OF THIS PRACTICAL:-HOSPITAL ADMINISTRATION MUST
SCAN THEIR ROUTER EVERY MONTH FOR VULNERABILITIES AND FIX IT
AS SOON AS POSSIBLE.
IF THERE ARE ANY SPELLING OR GRAMMAR MISTAKES PLEASE IGNORE
IT BUT I DON’T THINK IT WILL COME BECAUSE I HAVE CHECKED IT THRICE WHILE
POSTING IT
