It’s no kiddie joke: You’ve been pwned

Published

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.

Legion gets a pro makeover

Lenovo’s latest Legion gaming laptop, the Y530, pulls out all the stops to deliver a sleek looking computer at a lower price point, writes BRYAN TURNER

Published

Gaming laptops have become synonymous with thick bodies, loud fans, and rainbow lights. Lenovo’s latest gaming laptop is here to change that.

The unit we reviewed housed an Intel Core i7-8750H, with an Nvidia GeForce GTX 1060 GPU. It featured dual storage, one bay fitted with a Samsung 256GB NVMe SSD and the other with a 1TB HDD.

The latest addition to the Legion lineup has become far more professional-looking, compared to the previous generation Y520. This trend is becoming more prevalent in the gaming laptop market and appeals to those who want to use a single device for work and play. Instead of sporting flashy colours, Lenovo has opted for an all-black computer body and a monochromatic, white light scheme. 

The laptop features an all-metal body with sharp edges and comes in at just under 24mm thick. Lenovo opted to make the Y530’s screen lid a little shorter than the bottom half of the laptop, which allowed for more goodies to be packed in the unit while still keeping it thin. The lid of the laptop features Legion branding that’s subtly engraved in the metal and aligned to the side. It also features a white light in the O of Legion that glows when the computer is in use.

The extra bit of the laptop body facilitates better cooling. Lenovo has upgraded its Legion fan system from the previous generation. For passive cooling, a type of cooling that relies on the body’s build instead of the fans, it handles regular office use without starting up the fans. A gaming laptop with good passive cooling is rare to find and Lenovo has shown that it can be achieved with a good build.

The internal fans start when gaming, as one would expect. They are about as loud as other gaming laptops, but this won’t be a problem for gamers who use headsets.

Serious about security? Time to talk ISO 20000

Published

on

By EDWARD CARBUTT, executive director at Marval Africa

The looming Protection of Personal Information (PoPI) Act in South Africa and the introduction of the General Data Protection Regulation (GDPR) in the European Union (EU) have brought information security to the fore for many organisations. This in addition to the ISO 27001 standard that needs to be adhered to in order to assist the protection of information has caused organisations to scramble and ensure their information security measures are in line with regulatory requirements.

However, few businesses know or realise that if they are already ISO 20000 certified and follow Information Technology Infrastructure Library’s (ITIL) best practices they are effectively positioning themselves with other regulatory standards such as ISO 27001. In doing so, organisations are able to decrease the effort and time taken to adhere to the policies of this security standard.

ISO 20000, ITSM and ITIL – Where does ISO 27001 fit in?

ISO 20000 is the international standard for IT service management (ITSM) and reflects a business’s ability to adhere to best practice guidelines contained within the ITIL frameworks. 

ISO 20000 is process-based, it tackles many of the same topics as ISO 27001, such as incident management, problem management, change control and risk management. It’s therefore clear that if security forms part of ITSM’s outcomes, it should already be taken care of… So, why aren’t more businesses looking towards ISO 20000 to assist them in becoming ISO 27001 compliant?

The link to information security compliance

Information security management is a process that runs across the ITIL service life cycle interacting with all other processes in the framework. It is one of the key aspects of the ‘warranty of the service’, managed within the Service Level Agreement (SLA). The focus is ensuring that the quality of services produces the desired business value.

So, how are these standards different?

Even though ISO 20000 and ISO 27001 have many similarities and elements in common, there are still many differences. Organisations should take cognisance that ISO 20000 considers risk as one of the building elements of ITSM, but the standard is still service-based. Conversely, ISO 27001 is completely risk management-based and has risk management at its foundation whereas ISO 20000 encompasses much more

Why ISO 20000?

Organisations should ask themselves how they will derive value from ISO 20000. In Short, the ISO 20000 certification gives ITIL ‘teeth’. ITIL is not prescriptive, it is difficult to maintain momentum without adequate governance controls, however – ISO 20000 is.  ITIL does not insist on continual service improvement – ISO 20000 does. In addition, ITIL does not insist on evidence to prove quality and progress – ISO 20000 does.  ITIL is not being demanded by business – governance controls, auditability & agility are. This certification verifies an organisation’s ability to deliver ITSM within ITIL standards.

Ensuring ISO 20000 compliance provides peace of mind and shortens the journey to achieving other certifications, such as ISO 27001 compliance.
