Computer users are in big trouble, and the threat is faced by consumers and the business community alike, writes ARTHUR GOLDSTUCK.
Almost all users of online business sites and tools are potentially in big trouble – they just don’t know it.
When hackers broke into the most popular social network for professionals this year and the most popular file storage service a few years ago, they didn’t just make off with the passwords for their own use. They published their lists of stolen user names and passwords on hacker sites and on what is know as the Dark Web: an Internet underground that is accessed with specialised browsers.
The biggest problem is not so much that hackers managed to get to the passwords. The average person is simply not worth targeting by the hacker looking for a big payday.
There are two bigger issues, says Stefan Tanase, senior security researcher in Kaspersky Lab’s global research and analysis team. At Kaspersky’s annual Cyber Security Weekend in Malta last week, he offered a sobering perspective on just how easy the hackers have it.
First, he says, most people don’t change their passwords even when they have been compromised in this way – precisely because they feel these particular accounts wouldn’t interest anyone.
Second, once such details have been made available to others, there are armies of potential wrongdoers scouring these lists and testing accounts to exploit vulnerabilities. These can be as mundane as the opportunity to damage people’s reputation by posting vile content in their names.
But even if a password has been changed, a deeper threat remains.
“Since it is so difficult to keep track of one’s passwords across multiple sites, many people use the same standard password wherever they log on,” says Tanase. The sharp criminal mind – and there are many of those – uses publicly-posted stolen log-on credentials to try logging onto various other sites.
Sooner or later, they find their way into people’s Facebook, Twitter or Gmail accounts. Here they harvest profile information, combine it with the log-in credentials that have already proven fruitful, and proceed to break into anything from PayPal to online bank accounts. Where they have access to the victim’s email, it is a simple matter to alter security credentials, and begin transacting in that person’s name.
That is a worst-case scenario – but one that is all too real. There is a word for it: “pwned”. That’s hacker/youth/hipster slang for being “owned” by someone, or conquered.
Most of us have already been pnwed, but don’t know it. Visit the website https://haveibeenpwned.com and type in your email address. It will tell you exactly which stolen passwords lists include your details. If nothing comes up, you’ve kept your online registrations to a minimum. If something does come up, make sure you change your passwords on any sites mentioned – as well as on any other site where you use the same passwords.
“Whenever hackers publish a hacked database, the people at haveibeenpwned collect it and put it in a searchable database where the public can check for their email addresses,” says Tanase. “Don’t worry, it doesn’t make passwords available. But it includes an incredible number of accounts – from 152 leaked databases and 1,8-billion accounts ‘pwned’ by hackers.”
Tanase himself, an affable Romanian who has been analysing threats for Kaspersky Lab for much of this decade, admits he has been pwned.
“Even though I’m a security expert, and done everything right, I’ve been massively pwned. My information was leaked from at least five providers who were hacked.
“Even if you do everything right from a security standpoint, with two-factor authentication, complex passwords, don’t reuse passwords, don’t click on phishing links, you’re still vulnerable when a website gets compromised.”
There is little people can do to prevent one-off theft of passwords after an intrusion, but they can close the hole quickly by changing the password as soon as it has been compromised, If they don’t reuse passwords, then the blow to the ego of getting pwned will be the worst of the damage. If they do reuse passwords, then some serious maintenance suddenly becomes a priority.
For those who are deeply concerned about email and messaging privacy, Tanase has one simple piece of advice: “Crypto is your friend.” By this, he means that using encryption tools will generally safeguard you from personally targeted intrusions. “It is mathematics; it will never lie to you,” he says.
“There are tools you can use, you just need to know about them and also get your friends to use them because, if you’re the only one using it, its not encrypted.
“Let’s imagine every site you use is 100 per cent secure with 100 per cent customisable privacy controls, flawless platform with bulletproof protection. But what happens if one of your friends gets infected? They have access to your private emails sent to the friend, and access to all the information that contact has.
“I want to encourage people to explore the privacy and security settings that are available on all the big platforms, settings that were not available a few years ago, but you still need to enable them from your settings.
“Another important thing is two-factor authentication, where you need both a password and a device where you receive a one-time pin or password. It’s the easiest and quickest thing you can do to massively improve security of your online accounts, online banking security for your Facebook or email or Twitter account. It’s not available by default for simplicity sake, but if you really want security, look for it in the settings. The moment you do that, you make it twice as hard for hackers to access your account.
“Use a password manager to manage all your different passwords. And make sure you keep everything up to date to massively increase your level of security. If you want more security, you have to be okay with less convenience.”

Adobe: In October 2013, 153 million Adobe accounts were breached with each containing an internal ID, username, email, encrypted password and a password hint in plain text. The password cryptography was poorly done and many were quickly resolved back to plain text. The unencrypted hints also disclosed much about the passwords adding further to the risk that hundreds of millions of Adobe customers already faced.
Compromised data: Email addresses, Password hints, Passwords, Usernames
Dropbox: In mid-2012, Dropbox suffered a data breach which exposed the stored credentials of tens of millions of their customers. In August 2016, they forced password resets for customers they believed may be at risk. A large volume of data totalling over 68 million records was subsequently traded online and included email addresses and salted hashes of passwords (half of them SHA1, half of them bcrypt).
Compromised data: Email addresses, Passwords
Last.fm: In March 2012, the music website Last.fm was hacked and 43 million user accounts were exposed. Whilst Last.fm knew of an incident back in 2012, the scale of the hack was not known until the data was released publicly in September 2016. The breach included 37 million unique email addresses, usernames and passwords stored as unsalted MD5 hashes.
Compromised data: Email addresses, Passwords, Usernames, Website activity
LinkedIn: In May 2016, LinkedIn had 164 million email addresses and passwords exposed. Originally hacked in 2012, the data remained out of sight until being offered for sale on a dark market site 4 years later. The passwords in the breach were stored as SHA1 hashes without salt, the vast majority of which were quickly cracked in the days following the release of the data.

LG G7 arrives in SA
LG this week introduced South Africa to its latest premium smartphone, the LG G7 ThinQ, focused on bringing useful and convenient AI features to the smartphone experience.
Powered by the latest Qualcomm Snapdragon 845 Mobile Platform, the LG G7 ThinQ offers 4GB of RAM and 64GB of internal storage to run demanding tasks and apps with. It is equipped with a 6.1-inch Super Bright Display, but the LG G7 ThinQ remains compact enough to use with one hand.
Sporting a new design aesthetic for the G series, the polished metal rim gives the LG G7 ThinQ a sleeker, more refined look, complemented by Gorilla Glass 5 on both the front and the back for enhanced durability. Rated IP68 for dust and water resistance, the LG G7 ThinQ is also awarded MIL-STD 810 c certification, having been subjected to a range of extreme temperature and environment tests designed by the United States military.
The LG G7 ThinQ has an 8MP camera up front, rendering clear and natural selfies, with two 16MP cameras at the back that deliver higher resolution photos with more detail, as well as a Super Wide Angle configuration.
As with other leading brands, LG has evolved its signature camera by including AI functionality. The AI CAM offers 19 shooting modes for intelligence-optimised shots. Users can also improve their photos by choosing from an additional three effect options should the AI CAM recommendation not suit their taste.
The new Super Bright Camera captures images that are up to four times brighter than typical photos shot in dim light. Through the combination of pixel binning and software processing, the AI algorithm adjusts the camera settings automatically when shooting in low light.
Live Photo Mode records one second before and after the shutter is pressed for snippets of unexpected moments or expressions that would normally be missed. Stickers uses face recognition to generate fun 2D and 3D overlays, such as sunglasses and headbands, that can be viewed directly on the display.
New to the G series is Portrait Mode, which generates professional-looking shots with out-of-focus backgrounds. This effect can be generated using both front and rear standard lenses as well as the rear Super Wide Angle lens.
LG G7 ThinQ offers further AI functionality with the inclusion of Google Lens features. Google Lens is a new way to search using the AI and computer vision. Google Assistant and Google Photos allow users to access more information on objects such as landmarks, plants, animals, and books. It can identify text or visit websites, add business cards to contacts, events to the calendar or look up an item on a restaurant menu.
A button just below the volume keys launches the AI functionality. A single tap of this button launches the Google Assistant, while two quick taps launches Google Lens. Users can also hold down the button to start talking to the Google Assistant without the repetition of the OK Google command.
With Super Far Field Voice Recognition (SFFVR) and the highly-sensitive G7ThinQ microphone, the Google Assistant can recognise voice commands from up to five meters away. SFFVR is able to separate commands from background noise, making the LG G7 ThinQ an alternative to a home AI speaker, even when the TV is on. Commands for the Google Assistant have been increased in the LG G7 ThinQ so users can get more done with their voice alone.
“The LG G7 ThinQ is strongly focused on the fundamentals and its launch marks a new chapter for our company,” said Deon Prinsloo, General Manager for Mobile Communication, LG Electronics S.A Pty Ltd. “Through the combination of personalised and useful AI functionalities with meaningful smartphone features, this is LG’s most convenient and in the moment smartphone yet.”
