OSDP attack tool (and the Elvish word for friend)
OSDP supports, but doesn't strictly require, encryption. So your connection might not even be encrypted at all. Attack #1 is just to passively listen and see if you can read the card numbers on the wire.
Just because the controller and reader support encryption doesn't mean they're configured to require it be used. An attacker can modify the reader's capability reply message (osdp_PDCAP) to advertise that it doesn't support encryption. When this happens, some controllers will barrel ahead without encryption.
OSDP has a quasi-official “install mode” that applies to both readers and controllers. As the name suggests, it’s supposed to be used when first setting up a reader. What it does is essentially allow readers to ask the controller for what the base encryption key (the SCBK) is. If the controller is configured to be persistently in install-mode, then an attacker can show up on the wire and request the SCBK.
OSDP sample code often comes with hardcoded encryption keys. Clearly these are meant to be samples, where the user is supposed to generate keys in a secure way on their own. But this is not explained or made simple for the user, however. And anyone who’s been in security long enough knows that whatever’s the default is likely to be there in production.
So as an attack vector, when the link between reader and controller is encrypted, it’s worth a shot to enumerate some common weak keys. Now these are 128-bit AES keys, so we’re not going to be able to enumerate them all. Or even a meaningful portion of them. But what we can do is hit some common patterns that you see when someone hardcodes a key:
OSDP has no in-band mechansim for key exchange. What this means is that an attacker can:
You'll find proof-of-concept code for each of these attacks in attack_osdp.py. Checkout the --help command for more details on usage. This is a Python script, meant to be run from a laptop with USB<-->RS485 adapters like one of these. So you'll probably want to pick some of those up. Doesn't have to be that model, though.
If you have a controller you want to test, then great. Use that. If you don't, then we have an intentionally-vulnerable OSDP controller that you can use here: vulnserver.py.
Some of the attacks in attack_osdp.py will expect to be as a full MitM between a functioning reader and controller. To test these, you might need three USB<-->RS485 adapters, hooked together with a breadboard.
These issues are not, in isolation, exploitable but nonetheless represent a weakening of the protocol, implementation, or overall system.
Monkey in the middle, the beloved playground staple, extends beyond schoolyards into corporate networks, home desktops, and personal mobile devices in a not-so-fun way. Known as a monkey-in-the-middle or man-in-the-middle attack (MiTM), it’s a type of cybercrime that can happen to anyone.
Here’s everything you need to know about MiTM schemes specifically, how to identify when your device is experiencing one, and how to protect your personally identifiable information (PII) and your device from cybercriminals.
A man-in-the-middle attack, or MiTM attack, is a scheme where a cybercriminal intercepts someone’s online activity and impersonates a trusted person or organization. From there, the criminal may ask personal questions or attempt to get financial information; however, since the device owner thinks they’re communicating with someone with good intentions, they give up these details freely.
MiTM is an umbrella term that includes several cybercrime tactics, such as:
Cybercriminals gain access to devices to carry out MiTM attacks through three main methods: Wi-Fi eavesdropping, malware, or phishing.
The most common giveaway of a MiTM attack is a spotty internet connection. If a cybercriminal has a hold on your device, they may disconnect you from the internet so they can take your place in sessions or steal your username and password combination.
If your device is overheating or the battery life is much shorter than normal, it could indicate that it is running malware in the background.
If you can identify the signs of a MiTM attack, that’s a great first step in protecting your device. Awareness of your digital surroundings is another way to keep your device and PII safe. Steer clear of websites that look sloppy, and do not stream or download content from unofficial sites. Malware is often hidden in links on dubious sites. Try your best to stick to sites that have URLs beginning with “https.” The “s” stands for “secure.” Though not all “https” sites are guaranteed secure, they are generally more trustworthy than plain “http” sites.
To safeguard your Wi-Fi connection, protect your home router with a strong password or passphrase. When connecting to public Wi-Fi, confirm with the hotel or café’s staff their official Wi-Fi network name. Then, make sure to connect to a virtual private network (VPN). A VPN encrypts your online activity, which makes it impossible for someone to digitally eavesdrop. Never access your personal information when on an unprotected public Wi-Fi network. Leave your online banking and shopping for when you’re back on a locked network or VPN you can trust.
Finally, a comprehensive antivirus software can clean up your device of malicious programs it might have contracted.
McAfee+ Ultimate includes unlimited VPN and antivirus, plus a whole lot more to keep all your devices safe. It also includes web protection that alerts you to suspicious websites, identity monitoring, and monthly credit reports to help you browse safely and keep on top of any threats to your identity or credit.
A cybercriminal’s prize for winning a digital scheme of monkey in the middle is your personal information. With preparation and excellent digital protection tools on your team, you can make sure you emerge victorious and safe.
