Twitter warns about cyber attacks

Earlier this month, social media platform Twitter alerted a number of its users to the fact that their accounts may have been hacked into by something, or someone, known as a “state-sponsored actor.” While a warning of this kind is certainly not unprecedented – for some time now, both Facebook and Google have also been contacting any of their users who they think may have been targeted – it suggests that attacks of this type are becoming more widespread.

But how at risk actually are you from a state-sponsored cyber attack? Is your small or medium-sized business in danger of being targeted? And who is behind these hacking attempts? Well, going by the warnings recently issued by Twitter, reports so far suggest that people, companies or organizations connected to internet security and freedom of speech are currently most likely to be at risk. But ‘currently’ is somewhat ambiguous, for in the world of cybercrime things can happen at lightning speed, and someone who is a target today might be deemed out of danger tomorrow – and vice versa.

As always, the best form of protection is to be forewarned, and you can only do that by learning as much as you can about the latest threats, scams and attacks. If you are a Twitter user, be it personal or for business use, you may be wondering why you have not yet heard of these alerts. That’s because Twitter’s messages were only sent to a small, and mostly rather niche, group of users. The email informed these users that Twitter was contacting them as a precaution due to their accounts “possibly” having been hacked by the state-sponsored actors. The email also stated that they believed that the actors may (or may not) be associated with a government, and that those involved had been looking to obtain personal information such as email addresses, phone numbers and/or IP addresses. So far, so vague!

Twitter then goes on to say that, although they have no evidence that any accounts were compromised or any data was stolen, they are actively investigating. They also lamented the fact that they wished they could say more…but that they had no additional information at that time. The email goes on to attempt to reassure users that their accounts may not have been an intentional target, but admits that if a user tweets under a pseudonym, that Twitter understands they may have cause for concern. But with so many Twitter users tweeting under a different name – and perfectly innocently, at that – what’s the real cause for concern here?

The issue lies with the type of accounts that were mostly targeted. The majority of these belonged to people or organizations connected to, or concerned with, cyber security. In fact, Twitter even offered some handy advice on protecting your online identity, suggesting users read up on the subject at the Tor Project website. Somewhat coincidentally, one of the victims of the attempted Twitter account hack is an activist and writer who currently educates journalists about security and privacy – and who used to work for the Tor Project. Another is a Canada-based not-for-profit organization involved with freedom of speech, privacy and security issues, and one of its founders is a contractor for the Tor Project.

Other Twitter users who received the email are also involved in some way or another in cyber security, albeit as self-described “security researchers” or simply by way of following or engaging with the online security community. This might lead you to the conclusion that, if you’re not in the business of security and instead keep your tweets to sport, entertainment, and the latest must-have gadgets, you are not at risk. But we urge you not to be so hasty. That’s because, within that small group of people who were contacted by Twitter, a large proportion of them had nothing to do with activism, freedom of speech, calls for greater privacy, or anything of the sort.

This means that, far from brushing this latest round of cyber threats under the carpet, individuals and business owners – whatever industry they are in – do have at least some cause for concern. As yet Twitter has not released details of the state the “actors” are sponsored by, so for now we are none the wiser as to whether it’s a homegrown issue or one from further afar – say North Korea or China.

What does all this mean for you as a business owner or manager? It means that you should be taking your online security more seriously than ever. It’s no longer just your network that is at risk; now simply having an account on a social media site such as Facebook or Twitter could be providing less-than-desirable third parties with the portal they need to access your company’s private information.

Google and the art of safe mobile browsing

With the vast majority of end users turning to Google as their search engine or default browser of choice, it comes as no surprise to learn that the company takes security seriously. But in a perpetually changing landscape where anti-virus and anti-malware tools are constantly chasing their tails in order to stay up to date with the latest threats, there cannot be many small to medium-sized business owners who can afford to ignore the issues surrounding cyber security. So what exactly is the internet giant doing to keep your users – and your organization – safe?

With more than one billion people using Google’s search engine on their desktops, and over a billion more accessing it through mobile devices, it is clear that security is – or should be – paramount. Google already claims to protect desktop users with its Safe Browsing service, but what about its mobile users?

With cyber threats ranging from the annoying, such as adware, to the unsavory – hello spyware – and the downright terrifying (ransomware, we’re looking at you), mobile device users are increasingly demanding to know that they are being adequately protected when using Google’s products, tools and services. So in order to protect the mind-bogglingly large number of people who are using Google on their smartphones, laptops, notebooks and tablets, Google recently unveiled plans to extend its Safe Browsing service to mobile users – or at least to who are using Chrome on an Android device.

Whether you regard this as a blatant ploy to get users to switch to Android is something we’ll let you decide for yourself, but the fact is that Google is taking steps to protect its users. Back in August 2014, the company bolstered its Safe Browsing warnings with messages alerting users to unwanted software programs trying to sneak onto their computers by attaching themselves without warning to a legitimate download. In addition, both the Android platform and the Google Play Store have security measures in place to weed out potentially dangerous apps.

However, not every cyber security threat comes from an app or installation so, while Google is doing the right thing by guarding against threats in these areas, there are other issues that require a different means of protection. Enter social engineering, and phishing in particular, which can cause untold harm – such as data or identity theft – to a business or individual.

In order to protect against social engineering, an up-to-date list of malicious websites needs to be stored upon the device – this enables Google to send an alert to the user before they get ambushed. But there are problems with this which Google has had to overcome, not least of which is how to keep the list updated in the face of new threats. Compounding this issue further are factors that are unique to mobile browsing: mobile data speeds can be slow and connectivity patchy, depending where the user is. A fast, stable connection is crucial when the timing of an alert is paramount. Not only that, but using mobile data costs the end user money!

Bandwidth (and battery) limitations mean Google has had to find a way to ensure the data they send to users is as small as possible. Protecting their customers is crucial – but so too is not sapping battery life and data plans. Because this boils down to connectivity and speed factors, a device’s location is now taken into account. For example, if a known phishing scam is only affecting certain locations, only devices that are in that part of the world receive a warning.

Google also prioritizes data by sending information on a need-to-know basis – in other words, bigger threats take precedence over more minor issues. They have also designed the software to limit network traffic, and to be as light as possible on memory and processor usage.

Since its announcement in early December, Google is now protecting all Chrome users on Android devices as default, making Safe Browsing part of their Play services from Version 8.1 onwards. Chrome Version 46 is also the first app to initiate Safe Browsing.

How do you know whether you are protected by Safe Browsing mode? Go to your settings in Chrome, and check your Privacy menu. How do you know if your small or medium-sized business stands the best chance of survival in the face of a cyber attack or phishing scam? Talk to us today and we’ll be more than happy to share our up-to-date knowledge with you.
