20-Year-Old Exploit Finds New Life as ROBOT

There is no shortage of threats on the Internet, from situational issues to deliberate attacks meant to damage your company or steal your valuable data. While new threats pop up almost every day, some have been around for some time–so long, that many seem to not consider them as viable threats.
This can be seen in many considerably-sized Internet companies, including the likes of Facebook and PayPal, which recently tested positive for a vulnerability discovered in 1998 that enabled encrypted data to be decrypted.
When it was first discovered by researcher Daniel Bleichenbacher, this exploit was found in the secure sockets layer, or SSL, encryptions that protected (and still protect) many web platforms and websites. The algorithm that powers the RSA encryption has a flaw that permits a hacker to decrypt ciphertext without the key. The error messages that the encryption presents give hackers enough information to crack it.
As it would happen, instead of eliminating and reworking the flawed RSA algorithm, the SSL architects at the time simply created workarounds to limit the error messages.
This crypto-vulnerability, codenamed “Oracle,” provides “yes” and “no” answers to queries. This means that cybercriminals can phrase their queries specifically enough to ultimately retrieve enough information to form a detailed picture of the encrypted contents. This method is referred to as an adaptive chosen-ciphertext attack.
Recently, researchers have discovered that this vulnerability can be found on over a quarter of the 200 most-visited websites on the Internet, and on around 2.8% of the top million. Naturally, this includes Facebook and PayPal.
Researchers explained the oversight of what is now being called ROBOT, or Return Of Bleichenbacher’s Oracle Threat, as the result of too much focus being directed towards new threats, and the older ones being neglected as a result. As they said in a blog post:
“The surprising fact is that our research was very straightforward. We used minor variations of the original attack and were successful. This issue was hiding in plain sight. This means neither the vendors of the affected products nor security researchers have investigated this before, although it’s a very classic and well-known attack.”
These researchers sent their findings to vulnerable sites before going public so that a patch could be created.

With Great Power Comes a Greater Security Risk, Study Finds

Every user on your network adds an additional level of risk, whether it be risk of user error, making a mistake that causes a data breach, or worse. One would assume that a company’s biggest risk would come from an untrained employee that disregards security policies, but surprisingly, that’s not always the case. Research has shown that a company’s CEO along with the rest of its C-level executives are the greatest security risk.
There are multiple factors that go into this. Take for instance the sheer amount of sensitive data that a CEO has access to. Whereas an average employee may just have access to data pertaining to their job or their department, a CEO generally has carte blanche to access any data they desire.
Then there’s the fact that CEOs typically have a poor work-life balance. This means that they put in way more hours than the average employee. You don’t have to be an expert in risk assessment to understand that a user accessing a company’s network 60, 70, or even 80 hours each week is a far greater risk than a user that only accesses the network 40 hours per week.
Both of these factors contribute to another reason why CEOs make for such a large security risk: the mobile devices they carry. In an effort to always be connected to the office, a CEO’s mobile device may have unfettered access to company records and sensitive information–more so than an average employee’s personal device.
In the case of an employee that has separate mobile devices for their work and personal life (often a luxury that CEOs can’t enjoy), the risk of data leakage or a breach resulting from the device getting lost or stolen goes down dramatically. Alternatively, CEOs aren’t restricted to the office and this mobility increases the risk of being hacked outside the office, especially when it comes to using their mobile devices in venues that offer public Wi-Fi, like coffee shops, cafés, conference centers, airports, etc. Hackers know this and they go to great lengths to make public Wi-Fi hotspots traps for unsuspecting users. This is why CEOs should be wary about accessing public Wi-Fi, and why it’s preferable that CEOs even avoid public Wi-Fi altogether (unless you are using a secure VPN to access all of your data).
A 2017 security report by iPass confirms this risk of cyber-attacks at popular Wi-Fi hotspots. The report ranks the riskiest public venues as follows.
- Coffee shops and cafés, 42 percent.
- Airports, 30 percent.
- Hotels, 16 percent.
- Exhibition centers, 7 percent.
- Airplanes, 4 percent.
How much time do your company’s C-level executives spend doing business from these locations? The more business that’s done using Wi-Fi at these locations, the more of a risk an executive or even a mobile employee is to your organization.
Finally, CEOs are in a category unto themselves when it comes to another risk: CEO whaling scams. This is where scammers spend time researching the lives and motivations of CEOs so they can specifically target them with scams from a variety of sources, including email, phone calls, traditional paper mailings, and whatever other means they can use to get in contact with a CEO. This is an extremely dangerous scam because, unlike traditional scams like spam messages where the same message gets sent to thousands of people (and it’s often easy to recognize that it’s a scam), a CEO whaling correspondence is personalized to play on a CEO’s deepest fears and desires. For the scammers that go after CEOs like this, the effort is worth the time investment, due to the simple fact that CEOs make for such lucrative targets.
So, there you have it. CEOs are one of a company’s biggest security risks. For your business, this means you’ve got to take additional measures to ensure the protection of your C-level executives. Generally speaking, the same security plan and policies that work for the average employee won’t cut it for an executive, which is something you need to take into account when coming up with your company’s security and BYOD policy.
