You may think that political parties understand the need for good security, but back in 2016 the DNC suffered a major hack due to phishing emails.

Thanks to a sustained attack, Russian hackers were able to infiltrate email accounts of those involved within Hilary Clinton’s campaign to become president of the United States. And, as you know, the rest is history. However, not many people are aware of exactly how the DNC got hacked so extensively that highly sensitive information was obtained and then leaked to the public.

Although not every single detail has been revealed, we know enough that the hack was, in relative terms, a fairly simple execution. Naturally, you’re unlikely to be targeted by the same people who are involved in political attacks, but their methods are likely to be similar. Therefore, we’re going to take a look at how the DNC was hacked by phishing emails, so you can understand how to avoid it.

Phishing for DNC Secrets

The hack began on March 10th, 2016 and involved a batch of heavily disguised emails, which appeared to be sent by Google, being sent to key members of Hilary Clinton’s campaign team. These emails purported to be advising the recipients that their passwords needed changing in order to strengthen their security. However, the links contained within these emails sent users to a malicious website where strengthening security was the last thing on their mind. With these email accounts compromised, the hackers were then able to access private contact lists held within them.

Within a day, the hackers had access to confidential email addresses for key targets within the DNC campaign. And, almost immediately, the hackers began to send phishing emails to these email addresses in order to work their way higher up the chain of command. Despite the presence of two-factor authentication, the hackers’ persistence paid off as they eventually managed to breach the defenses of John Podesta, chairman of the DNC’s campaign. This email account, alone, provided access to 50,000 confidential emails.

This assault is believed to have been organized and orchestrated by the Russian cyber-espionage organization known as Fancy Bear. Despite accessing such a huge amount of emails from Podestra, Fancy Bear intensified their hacking campaign and this led to security experts becoming suspicious of methods being employed to dupe Google’s spam filter into accepting malicious emails into the inboxes of DNC targets. The clean-up operation, however, was too late and Podestra’s breached emails were soon published on Wikileaks.

Be Clever, Don’t Get Phished

The 2016 attack on the DNC is probably the most famous, and damaging, phishing attack in cyber-history. Simply due to a few members of staff clicking malicious links, an entire election campaign was brought to its knees. Reinforcing good email security, therefore, remains a crucial practice for any organization in modern business. Even with millions of dollars of security in place, the DNC fell victim to a simple phishing scam and, next time, it could easily be your organization.

What Should You Do When You Receive a Phishing Email?

Phishing emails are the scourge of our inboxes and there seem to be more and more each week, so what should you do when you receive a phishing email?

The aim of phishing emails is for the sender of said emails to obtain sensitive information from the recipient. This goal is realized by cleverly disguising the email to make it look as genuine as possible and, therefore, gain the recipient’s trust. Data targeted by phishing emails usually relates to sensitive details including login details and passwords. And this data leakage can cause serious harm to businesses with the average cost of a phishing attack on a medium sized business costing around $1.6 million.

No organization that wants to remain productive and competitive wants to deal with the chaos of a phishing attack, so we’re going to take a look at what you should do when you receive a phishing email.

Do Not Open Phishing Emails

The best way to avoid the dangers of phishing emails is very simple: Don’t open them! This, of course, is easier said than done as phishing emails have become incredibly sophisticated over the years e.g. spoofing email addresses. However, if for any reason whatsoever you do not recognize an email address or there’s something unusual about the email subject then it’s always best to err on the side of the caution. Instead, move the cursor away and get your IT team to investigate it before going any further.

Leave Links Well Alone

Opening a phishing email isn’t enough, on its own, to activate the malicious payload, but it’s very simple to do so. Phishing emails often contain links which, once clicked, send the user to malicious websites where malware is automatically downloaded to the user’s PC. This malware is usually very discreet and is able to run silently in the background where it is able to log keystrokes or even take control of the user’s PC. So, remember: if you don’t recognize the sender of an email, it’s crucial that you never click their links.

Don’t Respond

Phishing emails will often try to gain your trust by establishing a connection, so you need to be mindful of these deceptive tactics. By hitting the reply button, for example, you’re demonstrating to the hacker that not only is your email account active, but that you’re willing to engage. And, if a phone number is provided, never ever ring it as it will involve further social engineering and potentially a very high phone charge to a premium member. It may be tempting to respond, but always say no and move away from engaging.

Report the Email

Any form of hacking represents a serious threat to the security of your organization, so it should be every employee’s duty to report a phishing email as soon as possible. This allows your IT team to analyze the email and its contents before taking action. This could be as simple as deleting it securely or telling you that, actually, it’s safe to open. Ultimately, shared knowledge allows your entire organization to stay on top of phishing emails, so, even if you’ve clicked something you shouldn’t have, report it immediately.

4 Questions You Should Ask Before Clicking an Email Link

Aug 2018

We receive so many emails in business now that they’re a keen target for hackers. As a result, your organization needs to be more wary than ever with email.

The most common way for a hacker to take advantage of emails is by loading them with malicious links. These can be used to extract personal information, activate ransomware or send users to dangerous websites. And these emails are more than likely hitting your organization every day. Whilst the majority of emails with links embedded in them are genuine, it only takes one rogue email to cause severe problems.

To help you avoid the wrath of hackers, we’ve put together four questions you should ask before clicking an email link.

  1. Do You Recognize the Sender?

Trust is crucial when it comes to dealing with links contained within emails. If you don’t recognize the sender then the link should definitely be treated with caution as it could easily be a malicious link. Emails from work colleagues should be more trustworthy, but it’s always possible that their email account has been hijacked. So, even if you recognize the sender, there are still plenty of questions you need to ask.

  1. Does the Link Look Genuine?

If you received an email advising you to visit the Ophtek website then it would look something like www.ophtek.com or ophtek.com. However, if a hacker is trying to trick you into visiting a malicious website then the link may read slightly different e.g. ophtek.org or ophteksupport.com. If you’re ever unsure about the URL listed in a link then try Googling the URL and see whether it brings up a genuine website.

The other factor to look out for is whether the link written in the email is genuine. While the link could say www.ophtek.com the actual destination contained within the link could be completely different. Thankfully, you can double check this by hovering your cursor over any email link to display a popup window that lists the genuine destination.

  1. Do You Even Need to Click the Link?

A high number of malicious links prey on our worries, so, for example, emails that claim your bank account has been hacked are very common. The email will usually contain a link that promises to start an authentication process to secure your account, but these links are never genuine. More often than not, the email will reference a bank that you don’t even have an account with, so there’s absolutely no need to click any links inside it.

  1. Why is it a Shortened Link?

Shortened links may save space in emails, but there’s no reason why they should be used in business emails. More importantly, shortened links – provided by platforms such as Bit.ly and Goo.gl – are yet another way that hackers can disguise the destination of a link. Shortened links are particularly difficult to judge as, even if you hover your cursor over them, it’s impossible to tell where they will send you. Help is at hand, though, from platforms such as CheckShortURL which can expand shortened links to show their true destination.

Hide ‘N Seek Botnet Threatens the Internet of Things

Mar 2018

The Internet of Things (IoT) has a new security threat and this time it uses peer-to-peer communication to spread, infect and compromise devices.

In January 2018, security researchers working for Bit-defender discovered a new botnet which, although not related, has similarities to the Reaper botnet. Originally infecting just 12 IoT devices, the Hide ‘N Seek botnet had soon amassed over 32,000 IoT devices by the end of the month. With the ability to steal data, take control of the device and run malicious code, Hide ‘N Seek represents a serious threat.

Understanding new and emerging threats to IoT devices is crucial if you want to protect your organization’s network, so it’s time to investigate Hide ‘N Seek a little closer.

Hide ‘N Seek is No Game

A brand of IP camera manufactured in South Korea appears to be the initial infection source for Hide ‘N Seek, but the botnet is actively attacking other IoT devices. Using randomly generated IP addresses, Hide ‘N Seek attempts to connect to any devices listed against these addresses. If the botnet succeeds in connecting then it either uses default login/password combinations to gain access or performs a brute force attack using a dictionary list to crack the login credentials.

With access obtained, Hide ‘N Seek analyses the device to discover any potential vulnerabilities such as the ability to download malware or launch DDoS attacks. The remote botnet hacker also has the option of executing any command they wish on the infected device; this option provides them with the chance to steal any files they wish. The capabilities of Hide ‘N Seek are clearly advanced and innovative, but what’s even cleverer is that it appears to be constantly redesigning itself to minimize detection.

Communication between the infected devices is made possible by the peer-to-peer network at the heart of Hide ‘N Seek. Using peer-to-peer software for hacking is nothing new, but previous methods have always involved modifying existing torrent software. Hide ‘N Seek is taking hacking to a new level by using completely custom built peer-to-peer software which has no central command unit; therefore, closing this network down is virtually impossible.

Combating Hide ‘N Seek

The advanced design of Hide ‘N Seek is proof that it’s the work of highly skilled hackers, but, once again, the vulnerability being exploited is the use of default passwords. Let’s face it, giving a hacker a key to a locked door is the worst form of security you can imagine, but this is exactly what default passwords are. And this is why password security remains the number one priority for any devices within your network, whether they’re connected to the IoT or otherwise.

By changing these default passwords while devices are on isolated networks, your organization can seriously increase the strength of their defenses. Otherwise, you’re leaving your networks at the mercy of malicious botnets such as Hide ‘N Seek. And, believe me, just as Reaper wasn’t the last IoT botnet, neither will Hide ‘N Seek be the final word in hacking in this new IoT landscape.

Feb 2018

If you want to keep the IoT (Internet of Things) secure in 2018 then you’re going to have your work cut out due to the number of threats on the horizon.

Significant progress has been made in the last couple of years when it comes to understanding the security concerns presented by IoT devices, but this is only encouraging hackers to become more innovative. And 2018 is going to deliver more IoT security threats than ever before, so you’re going to need to be ready for this surge in activity and the new hacking methods employed.

Let’s take a look at the most pressing IoT security concerns coming in 2018.

  1. IoT Attacks Being Undetectable

Many IoT attacks take place on a micro scale compared to large scale attacks such as Distributed Denial of Service Attacks. The problem with micro attacks is that conventional security systems are unlikely to recognize them as a threat, whereas major attacks are likely to ring alarm bells very quickly. Therefore, investing in highly sensitive security systems and manual monitoring may become vital to any organization using IoT devices.

  1. Automation Will Become More Important

Some organizations can have thousands of IoT devices operating on their network at any one time, so manually monitoring this activity is virtually impossible. And that’s why automation and artificial intelligence could prove highly popular in 2018 when it comes to providing a front line defence against IoT attacks e.g. installing crucial firmware upgrades immediately.

  1. The Irresistible Allure of Cryptocurrency

You only have to take a quick look at the financial headlines to understand just how valuable cryptocurrencies are at the moment. And, to a hacker, the financial rewards on offer are hard to resist. The Satori botnet, for example, takes control of IoT devices and also allows the hackers to exploit Bitcoin mining software. So, if your organization is involved with cryptocurrencies in any capacity, it’s going to pay to monitor your activity very closely.

  1. More and More Devices Will Be Targeted

Automobiles, security cameras and baby monitors are just a small selection of the IoT devices which have been hacked in the last couple of years, but this is set to increase further in 2018. In particular, devices which come with weak passwords (or even no password) are constantly being scouted by hackers. And, when they discover one, this can easily be leaked online, so the need to enforce a strong password culture remains essential.

  1. Privacy Concerns

Trusting IoT devices to transmit and receive personal and sensitive data is going to come under serious scrutiny in 2018. Due to the recent IoT attacks which have exploited weak passwords and poor security protocols in IoT devices, the public concern is growing over how their data is handled. Naturally, hackers are excited by the prospect of being given a free run at such a huge number of vulnerable devices without adequate security frameworks in place. 2018, therefore, is going to find organizations having to soothe customer concerns by only working with secure hardware and software.
