Every use of Internet service is associated with risks. But almost nowhere can this have such drastic consequences as with online banking. Even the smallest security mistake could put your login data - or even your TANs - into the wrong hands and your account could be emptied from anywhere in the world.
In this article, we will tell you how online banking attacks work and how you can
protect your hard-earned money from them.
How Do Attacks Online Banking Work?
The most common form of attack is to steal your credentials and then withdraw funds from
your account or shop online. The exact procedure is always different, but
usually malicious software, manipulation tactics, or a combination of both are
used. Here are some of the most common attack vectors:
Phishing
Phishing is and will
remain one of the most popular approaches. In this type of attack, the
criminals send fake e-mails that resemble security messages from reputable
banks. The link often contained in it leads to a fake website that is
almost indistinguishable from the original. Enter your login data here and
serve the attackers your confidential information on a silver platter. Sometimes
the email may have an attachment that is supposed to be an important document. Then,
once you open it, malicious software will be installed on your computer.
Man-In-The-Middle Attacks
“Man-in-the-middle”
(MITM for short, literally translated “man in the middle”) means that
communication between two interlocutors (or their devices) is intercepted. In
this way, cybercriminals can pass themselves off as the other interlocutor -
in this case you and your bank - and not only “eavesdrop” on your communication
but also manipulate it for their own obscure purposes. So while you
believe that you are communicating with your bank through a private connection,
your messages are actually being received and sent by the attackers. With
the modified version of the “man-in-the-browser”, the whole thing takes place,
as the name suggests, directly in the browser. The SSL encryption, which
is actually supposed to protect you from conventional man-in-the-middle
attacks are ineffective.
Malware
Malware
such as banking Trojans and Infostealers are supposed to steal bank data, for
which purpose they usually infiltrate running browser processes. This
gives you full control over which pages you visit and what exactly you do on
those pages. The banking malware can then also record all entered user
data and passwords. Also, it can manipulate the websites displayed
without you noticing.
In this
way, for example, transfers can be modified and redirected to other accounts. It
also happens that existing forms on the bank websites are changed to
request multiple TANs. Together with the copied login data, the attackers
can then use these TANs to gain access to your account. Some notorious
examples of banking malware include:
·
Zeus: The Trojan integrates the infected devices
into a gigantic botnet and uses website monitoring and
keylogging (recording of keystrokes) to steal bank access data.
·
Qakbot: The malware developed by the
hacking group Mealybug spreads like a worm and is also designed to collect bank
access data.
·
Ramnit: This is a file infector that is
distributed via removable media. It collects various login data, including
those for online banking
How Can You Protect Your Account?
1. Don't Blindly Trust Email.
Phishing
is such a powerful attack method because it exploits the weaknesses of human
nature. The best way to counteract this is to remain vigilant about your
email. Double-check each link in your email. Only open attachments if
absolutely necessary. It is also important to remember that a reputable bank
will never ask you to provide access data such as your full password, PIN or
TANs.
2. Use Two-Step Authentication.
Two-factor
authentication offers an additional layer of protection by requiring a unique
code to be entered in addition to the user name and password. Many banks
provide you with a small device that generates a new code every time you log
in. Please note that sending the code as a text message is not entirely
secure because it is relatively easy to intercept.
3. Keep Your Software Up To Date.
Many
attacks take advantage of vulnerabilities in software. To close these
security gaps and make their applications more secure, developers publish
updates. Always install these so that the risk of an attack remains as low
as possible. The easiest way to do this is to activate automatic updates.
4. Never Enter Sensitive Information on
A Public Wi-Fi Network.
In recent
years there has been an increasing number of public WLAN access. Unfortunately,
you can't necessarily trust them. Many of these public networks are
unencrypted and have no security precautions. Anyone who connects their
device to it is easy prey for man-in-the-middle attacks. Plus, you can
never be sure if it's not a honey pot hotspot. These are public and free
WLAN access points set up by criminals to gain access to confidential data. So
never enter your bank access data in a public WLAN. Better wait until you
are back home and surf your private network. If that isn't possible, use
your cellular data or invest in a commercial VPN service.
5. Enable Account Notifications.
Many banks
offer you the option to activate notifications so that you are informed of
certain activities in your account. For example, you can have messages
sent to you when a certain amount of money is withdrawn or the credit reaches a
certain value. These notifications cannot prevent attacks, but you will be
informed immediately of any suspicious activity and you can take
countermeasures as soon as possible.
6. Use Strong Passwords.
Sometimes passwords are
not stolen but simply guessed by so-called brute force or dictionary attacks. Minimize
the risk of such threats by choosing a long, unique, and random password. You

more information.
7. Be Careful on Mobile Devices Too.
Too often it is
forgotten that mobile devices can also fall victim to banking malware or other
malicious software. So always use your bank's app, as it is usually more
secure than the mobile browser. Mobile devices are also much easier to
steal than a computer. It is therefore essential to protect it with a
password, a PIN, or your fingerprint to make it more difficult for thieves to
access your data. For additional protection, it is also worth investing in proven mobile security software.
8. Get Reliable Anti-Malware Software.
Also, one of the
safest precautions you can take to protect your account from digital attacks is
to buy reliable antivirus and anti-malware software. A good solution
detects and blocks potential threats before the malware can make changes to
your system that could compromise your bank credentials and other sensitive
information. If you are looking for a resource-saving solution that offers
