smartphone security

We increasingly live in a mobile dominated world in which Smartphone sales have skyrocketed whilst traditional PC sales have stalled. With portable devices likely to be the future of many people’s IT use – we’ve put together a few of the main smartphone security threats you need to be aware of.

• Mobile Phishing & Fake Apps

Phishing websites which pretend to be your bank in order to get your personal or financial details have been around for many years, but for few people imagine that this is also a big risk on their smartphone.

Fake apps are the most obvious modern incarnation of this scam. IT security specialist ESET recently showed that a popular app like Prisma spawns multiple fakes online, downloaded unwittingly over 1.5 million times before being pulled from Google Play, with many containing harmful malware which attempt to steal personal information.

Don’t attempt to download an anticipated app before it’s official release date, as it’s likely you’ll be downloading a fake. Avoid downloading apps from unknown third-party websites, check the comments for warnings from other users, and invest in mobile antivirus to intercept downloaded threats to your smartphone security.

• Old-fashioned Theft

In addition to fitting in your pocket, your phone contains a staggering amount of personal information about you which makes theft a real danger – everything including your personal details and those of friends/family, your emails, GPS coordinates of places you regularly visit and more: all stored on the device.

Home Office research suggests iPhones are the device most likely to be stolen – perhaps reflecting the Apple smartphone’s high value, quality and distinctive branding.

In addition to setting numeric pin codes on every device to prevent the danger of theft, tracking and lifesaving wiping tools like are strongly advised.

• Public Wi-Fi Networks

With the proliferation of portable devices, many businesses, particularly in retail, offer public Wi-Fi hotspots to customers.

The problem with this is that you’re sharing a network with… whom? Terrifying free tools like [Redacted – obviously] and [Redacted] allow anyone on a shared public network to view insecure websites you visit, and snoop on any keystroke you type.

Not every public Wi-Fi network is a security nightmare, but it’s sensible to avoid using public Wi-Fi to do anything sensitive, such as online banking. A 4G data connection or simple telephone banking is the easiest alternative if you’re on a mobile phone, and likely to be more secure than a public Wi-Fi Network.

It should probably go without saying that you shouldn’t connect to entirely unrecognised, unsecured or unknown Wi-Fi networks either. For obvious reasons.

• Being Personally Targeted

The problem with the wider shift to portable devices is that we carry our workplace into the outside world. Many of us expect complete access to our business data on our smartphone (as we would on our PC) wherever we are.

But carrying your work phone outside work means you’re also outside the protection of in-house IT security software and firewalls.

A simple phishing email can easily be targeted to you outside working hours when you’re ‘off-guard’, and the potential loss of confidential company data could be devastating.

Of course, many of the best IT security software providers now offer Android & iOS smartphone versions of their antivirus software – so why not extend your business’ IT security to your smartphone?

fake invoices

This week’s IT security alert from Lineal – fake invoices which ask users to run a dangerous piece of code.

The example above comes from a fake Word document emailed with a typical text line, such as ‘Please check this invoice’ or ‘Double check my numbers for me’, to an unsuspecting user.

Upon opening, the document appears to load a popup from Office 2016 prompting the user to ‘Enable Content’ for compatibility purposes, before they can view the detail of the ‘invoice.’

In fact, the display is just an image within the word file, and the ‘Enable Content’ content button instead runs a piece of Visual Basic code downloading unknown malware from the internet.

The scam relies on users’ curiosity at the unusual $1999.00 charge, and upon reaching a user still running an outdated version of Microsoft Office.

Several measures can be taken to prevent this kind of attack:

• Don’t click any popup that doesn’t visibly pop ‘open’ in Microsoft and don’t ‘Enable Content’ you can’t see in a document.

• Consider an email filtering service like Barracuda – in the above example, Barracuda had recognised this email as malicious and stripped the code from the document before placing it in the correct email inbox for the intended recipient.

• Invest in a high-quality antivirus and IT security software like ESET – using sophisticated heuristics and live scanning ESET can block this kind of threat, and advanced versions operate a comprehensive watchlist of fake ‘phishing’ scams which might try to imitate legitimate companies online.

• Move to Microsoft Office 365 – Microsoft’s cloud subscription model now ensures that you’ll always have the most up-to-date version of Microsoft Office, and therefore that if a document gives you this kind of message, it may be a scam.

Zepto

Yesterday Lineal’s team successfully rescued a client from a new ‘zero-day’ Cryptolocker Virus which nearly destroyed many of their files.

The dangerous variation of the ‘Zepto’ cryptolocker, only identified online during the last 24 hours, is believed to be a brand new threat originally derived from ‘Locky’ ransomware.

An employee at one of Lineal’s IT support clients recently opened an email containing an infected file – a malicious piece of obfuscated code written in Visual Basic scripting language. The installed Zepto cryptolocker began encrypting the company’s files, readying to demand a heavy ransom.

In a coordinated attack, an outside user also forced access to our client’s server, instructing it to begin sending fake Barclays ‘phishing’ emails, attempting to criminally capture banking details.

Our team caught both threats early, forcefully locking out the intruder in mid-session, identifying the employee who introduced the threat, and quarantining the infection with ESET’s business endpoint security. 

Lineal then notified ESET about Zepto to help with future identification, having avoided the need to restore all the clients files from backup at great disruption.

The landscape of online security threats is rapidly changing, and Cryptolocker variants have spread quickly in recent months.

In this case Lineal’s rapidly responding team and professional security software helped our client dodge the huge potential losses from the security breach – and highlighted how vital it is that organisations of all sizes take proactive steps to protect their IT from hostile intrusion.

Hundreds of people have received new types of phishing emails which knows the individual’s home address.

Clicking the link in the dangerous email, which as a appears very authentic request to pay an overdue invoice, installs devastating cryptolocker ‘ransomware’ on the user’s computer.

The virus then begins encrypting files, demanding a ransom be paid to unlock the user’s data.

According to the BBC the unconnected company cited in the email, cotton fabric manufacturer British Millerain Co Ltd, have received more than 150 phone calls from individuals concerned that they owe money.

Phishing emails and websites, which typically mimic official bank or company communications to trick vulnerable users into making payments to criminals, are becoming increasingly sophisticated.

The use of an individual’s personal address, and higher quality written English, suggests the original creator of the email has gone to greater lengths to make the email look convincing and to avoid detection.

It is also likely that the matching address originates from stolen, legitimate customer data, accounting for users’ recognition of the way they write their own home contact details.

New threats are constantly developing, and Lineal recommend installing an antivirus software with a strong record of catching emerging online threats – such as ESET.

Always follow some simple rules:

• Never click a link or open an attachment from any suspicious email whose origins you do not recognise.

• Banks and similar will NEVER request your private passwords, pin numbers or other confidential information. Do not disclose these to anyone.

• If hit by cryptolocker style ransomware, every second counts – seek professional technical support immediately.

• Always keep a regular, separate backup of your files.

• Invest in reliable Antivirus software like ESET to protect your device(s).

Smartphone banking app malware hacks SMS codes

A dangerous new banking app malware has successfully bypassed smartphone security used by some of the world’s biggest banks.

Customers of Australia’s four biggest banks, and numerous New Zealand Banks, have all been declared at risk from the malware which activates when using a banking app, copying details from login screens.

Most worryingly, the malware can also divert two-factor authentication codes sent to a given smartphone by SMS – and pass the code to criminals, breaking a tried and trusted system used by many online financial apps around the world.

ESET security systems (commonly deployed by commercial clients for server and endpoint security) recently detected the extremely sophisticated malware, which downloads via fake Adobe Flash windows on video streaming websites.

On Android, personal users can uninstall the malware manually via Settings > Apps > Flayer > Uninstall, and are advised to only accept approved downloads from trusted public sources such as Google Play.

Commercial clients should take similar precautions against banking app malware and similar, protecting company devices behind specialist security systems.
