Cyber139- Protect, Prevent Cybercrime

Cyber crime costs small businesses the most

December 29, 2016 By Cyber SecurityNo Comments

New research has found that cyber crime is disproportionately effecting small businesses the most.

The Federation of Small Businesses (FSB) has found that small firms are unfairly carrying the cost of cyber crime in an increasingly vulnerable digital economy.

The report Cyber Crime: How to protect small firms in the digital economy suggests smaller firms are collectively attacked seven million times per year, costing the UK economy an estimated £5.26 billion.

Despite the vast majority of small firms (93%) taking steps to protect their business from digital threats, two thirds (66%) have been a victim of cyber crime in the last two years. Over that period, those affected have been victims on four occasions on average, costing each business almost £3000 in total.

Cyber crime costs small businesses disproportionately more than big businesses when adjusted for organisational size.

Currently the responsibility largely falls on small businesses to protect themselves. FSB is calling for more support to be given to those smaller firms least able to bear the burden of the increasing global cyber threat.

Almost all (99%) of the UK’s 5.4 million small firms rate the internet as being highly important to their business, with two in three (66%) offering, or planning to offer, goods and services online. Without intervention, the growing sophistication of cyber attacks could stifle small business growth and in the worst cases close them down.

Mike Cherry, FSB National Chairman, said: “The digital economy is vital to small businesses – presenting a huge opportunity to reach new markets and customers – but these benefits are matched by the risk of opportunities for criminals to attack businesses.

“Small firms take their cyber security responsibility very seriously but often they are the least able to bear the cost of doing so. Smaller businesses have limited resources, time and expertise to deal with ever-evolving and increasing digital attacks. We’re calling on Government, larger businesses, individuals and providers to take part in a joint effort to tackle cyber crime and improve business resilience.”

The types of cyber crime most commonly affecting small businesses are phishing emails (49%), spear phishing emails (37%), and malware attacks (29%).

Small firms are also concerned about hacking and fraud when the card is not present, with the average information breach setting them back 2.2 days.

To combat this, four in five small firms (80%) use computer securing software, and well over half (53%) perform regular updates of their IT systems.

The FSB report also found room for small firms to improve security.

Currently just a quarter of smaller businesses (24%) have a strict password policy, four per cent have a written plan of what to do if attacked online, and just two per cent have a recognised security standard such as ISO27001 or the Government’s Cyber Essentials scheme.

Mike Cherry added: “Small firms are understandably focussed on building their businesses and creating the jobs which drive economic growth. The vulnerabilities of the digital world affects everyone and the responsibility for improving resilience should not be left to the group with least resource to do something about it.

Yahoo confirms one billion users have had data hacked

December 15, 2016 By Cyber SecurityNo Comments

Bob Lord, chief information security officer at Yahoo, admits details of the breach in a blog post.

“We believe an unauthorised third party, in August 2013, stole data associated with more than one billion user accounts. We have not been able to identify the intrusion associated with this theft,” he said.

Speaking to Computer Weekly, Jonathan Care, a research director at market watcher Gartner, said Yahoo’s lack of clarity on this point was troubling.

“The implication is that Yahoo has overly focused on deploying protective technologies, and has not put in place effective analytics, detection and response systems and processes,” he said.

“From what we do know, the attackers made use of cookie masquerading, pass-the-hash and a state-sponsored actor. This gives strength to the importance of a strong detection plan.”

The incident came to light after US law enforcers shared files with the company that a third-party claimed contained Yahoo user data.

“We analysed this data with the assistance of outside forensic experts and found that it appears to be Yahoo user data,” said Lord.

Yahoo admits that staff knew about the data breach two years before it was confirmed publicly, and that the incident could affect the $4.83bn sale deal with Verizon.

“For potentially affected accounts, the stolen user account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (using MD5) and, in some cases, encrypted or unencrypted security questions and answers.”

“We are notifying potentially affected users and have taken steps to secure their accounts, including requiring users to change their passwords,” he said. “We have also invalidated unencrypted security questions and answers so that they cannot be used to access an account.”

Which suggests that many personal questions have been hacked as well.

This latest breach comes several months after Yahoo revealed details of another historic attack on its systems, dating back to 2014, which led to the personal details of at least 500 million users becoming exposed.

At the time, the incident was reported to be the largest publicly reported breach of its kind, but the August 2013 one is understood to be considerably bigger.

After news of the 2014 hack broke, Yahoo confirmed some staff knew about it several years before details were publicly disclosed, and acknowledged that it could lead to Verizon withdrawing its $4.83bn bid to acquire the company.

In light of its latest disclosure, questions are now being raised about how the news may affect the deal, given Verizon went on record in October 2016 to say the previous breach could pave the way for it to drop its bid.

“It also emphasises the importance of purchasers understanding the security risks of target businesses and building in contractual mechanisms to adjust the price, or even allow them to walk away from the deal if breaches like these come to light before completion.”

“Clearly, the upshot of this is that we need to realise that it’s no longer a case of ‘if we’re targeted or unlucky’, but that we are all targets.”

Camelot’s National Lottery accounts are hacked

November 30, 2016 By Cyber SecurityNo Comments

It could be you- as tens of thousands of online lottery Camelot players’ accounts are hacked.

National Lottery operator Camelot says the login details of thousands of people who do the lottery online have been stolen.

There are 9.5 million national lottery players registered online, but Camelot said only around 26,500 accounts were accessed. It added that fewer than 50 accounts have had suspicious activity, such as personal details being changed, since the breach.

The company said it unearthed “suspicious activity on a very small proportion of our players’ online National Lottery Accounts” during its online security monitoring on 28 November 2016.

It added that there has been no unauthorised access to core systems. “In addition, no money has been deposited or withdrawn from affected player accounts,” said Camelot.

“However, we do believe that this attack may have resulted in some of the personal information that the affected players hold in their online account being accessed.”

The company said it is now trying to find out what happened, but it believes that “the email address and password used on the National Lottery website may have been stolen from another website where affected players use the same details”.

The affected accounts have been suspended and Camelot will contact the account holders to re-activate them. Camelot added that it is working with the National Cyber Security Centre on the incident.

Are you an online lottery player?

If so, just crossing your fingers is not enough. To mitigate risks in the short term, account holders should update passwords and avoid using the same password across multiple sites.

Why are businesses ignoring cybercrime and cyber risks?

November 21, 2016 By Cyber SecurityNo Comments

How can cyber security professionals help businesses to understand the cyber risks?

Business owners don’t like spending money on anything that doesn’t make them more money. Even insurance is a grudge purchase. I’m never fond of paying a high premium, but if there’s a risk that I could lose my livelihood and house if I fail to get the right insurance cover, then I accept that.

Mitigating cyber risk is exactly the same. If companies don’t do it, then they could go out of business.

But there’s definitely over-confidence in the space, and I often hear “well, it will never happen to us, we’ve just installed anti-virus on all of our laptops”.

So exactly how do you give the business that niggling feeling that encourages them to mitigate security risks? The reactive approach definitely isn’t the right way, demanding cash after something has happened to plug a hole.

The sales led approach isn’t the right way, where security suppliers force silver bullets down your throat and you end up buying something to help them meet their sales targets, regardless of how nice it makes your treasured server rack look.

It’s about taking a proactive stance, and dealing with cyber security before something happens; and being prepared to tell security suppliers where to stick their hardware if it doesn’t fit into your security programme.

I’ve never seen a business turn down a carefully prepared cyber security risk mitigation programme that fits the business. Fortunately, creating one is remarkably simple. Define scope. Carry out a security audit on said scope. Conduct a gap analysis, work out three costed options with pros and cons to address each gap, and present to the business.

But that still doesn’t mean the business will buy in. We’re missing that niggling feeling. Much as I dislike scare tactics, now would probably be a good time to think about them, with a short, sharp exercise that demonstrates to the business exactly what could go wrong in their cyber world.

Simulate a phishing email. It’s easy enough. Put an EICAR (European expert group for IT-security) malware test file on your CEO’s laptop. Take your CFO’s laptop away for an hour and simulate critical hardware theft. Leave a suspicious package in the mail room. Simulate a web server hack.

These exercises would take less than an hour of the board’s time and, while they won’t get the cheque book out, they will raise awareness over time. Throw in a few fire drills to keep their minds off cyber for a bit. Simulate a flood. The point being, over time, your business can become cyber-aware; and ultimately this loosens the purse strings and gets you that next hire and support for implementing change.

UK organisations are still not taking ransomware seriously enough

November 2, 2016 By Cyber SecurityNo Comments

UK organisations are still not taking ransomware seriously enough, and continue to fall prey to this method of low cost, low risk cyber extortion.

Businesses still get caught by ransomware, even though straightforward avoidance methods exist.The CryptoLocker ransomware caught many enterprises off guard, but there is a defence strategy that works.

Another factor promoting the popularity of ransomware among attackers, is that unlike many other forms of malware, ransomware does not require any special user rights.

“If your system gets infected by a keylogger, it has to escalate privileges to become an administrator on the system so it can survive a reboot, but all ransomware needs is access to the files the infected user can access,” said chief research officer at F-Secure Mikko Hypponen.

“This makes them a unique problem because you can’t fight ransomware by locking down systems, restricting user access or removing administrator privileges from users.

“I fully support this approach to security. Only give users access to what they need, take away admin privileges, but none of these things will protect against ransomware.”

The most effective way to counter ransomware, said Hypponen, is to backup all critical data, but many organisations are failing in this.

“They may be backing up data, but they are typically not doing it often enough. They are not backing up all the information they really need because files are not being saved to the right folders, and they are not testing their backups regularly. Even if they have backed up the information, they are often unable to restore it to a usable form,” he said.

“In addition to regularly tested backups, organisations should also ensure they would be able to detect and respond to a live ransomware Trojan on their network before it has succeeded in locking up all the data,” said Hypponen.

One way of approaching this is to plant dummy “canary” files throughout the network. These should never be touched by legitimate users and act as alarms. If these files are touched, it points to malicious activity on the network.

Ransomware is also popular, he said, because its developers are able to outsource the risk to partners whose role is infect computers in return for a share in the money extorted from victims.

In addition to ransomware, another new business model for cyber criminals is circumventing the fingerprint locks on iPhones.

“Once fingerprint readers were added to iPhones, users were able to lock and unlock them quickly and easily. This meant that if the phone was stolen, it was useless and could be only sold for spares, which did not yield very much,” said Hypponen.

But researchers are now starting to see criminal organisations that are able to trick victims of mobile phone theft into revealing their iCloud credentials.

“Victims typically receive an email message a few days after their phone is stolen to say it has been located using the ‘track my iPhone’ facility, telling them to click the link embedded in the message,” said Hypponen.

“But the link takes them to a phishing site that asks them to log into their iCloud account, and once they have done that, the criminals have the information to reset the stolen phone and sell it as a fully working device.”

The second lesson learned in 25 years of cyber security, said Hypponen, is that people will never learn, and that user education is a waste of time.

“It doesn’t matter how many times you tell them, they will always double click on every executable. They will always follow every link, they will always type their password and credit card number into any online form that asks for that information, and they will always post their credit card picture and even CVV numbers on Twitter,” he said.

Admitting this may be overly pessimistic, Hypponen said that instead of trying to “patch” people by educating them, the responsibility should be shifted to those better equipped to handle it.

“We should be thinking about where we really want the responsibility to be,” he added. “Do we really want people to be responsible for security when most of them can’t handle it, or should we be thinking about taking the responsibility away from the user and giving it to operating system developers, security companies, and internet service providers and mobile operating firms that provide the connectivity that causes the problems in the first place?”

No final fix for cyber security

October 31, 2016 By Cyber SecurityNo Comments

There really is no final fix solution endgame when it comes to cyber security.

The claim was made by security industry veteran and chief research officer at F-Secure Mikko Hypponen and two of the most valuable lessons in cyber security are to know your enemy and not to rely on users to be secure.

“We will always have cyber security problems because we will always have bad people, which means job security in security is likely to continue for ever,” he told the Wired Security conference in London.

Cyber attackers are continually evolving their techniques and capabilities to steal and monetise data in new ways, which means the goalposts are continually moving.

“If we were still fighting the enemy of 10 years ago, we would be in great shape,” he said, alluding to the security tools that have been developed since then, as well as the security improvements in software.

“Attackers will always have the upper hand because they have the luxury of time to study our defences, while defenders do not have that luxury, so it is an unfair contest – a never-ending race.”

Reflecting on lessons learned over his 25 year career in information security, Hypponen said the most important thing is to understand the adversary.

However, he said the days of being able to do that easily are long gone, with most organisations finding themselves faced with a whole range of attackers.

They are all looking to gain something, said Hypponen, whether they are hacktivists supporting a cause, nation state actors or criminals.

“But for most organisations, criminals are the most likely to be attacking them,” he said, noting that of the 350,000 to 450,000 new malware samples that F-Secure sees on a daily basis, 95% comes from organised cyber crime groups.

“It is different when you get targeted by foreign intelligence agencies, because they are really bad, but most organisations are not targeted by foreign spies because most organisations are of no interest to them,” he said.

Although these cyber criminals like to portray themselves as Mafiosi, Hypponen said most are just “geeks” looking to make money from selling things such as hacked PayPal accounts and credit card details along with step-by-step guides on how to use them to make money.

Ransomware most popular form of cyber crime

Ransomware that encrypts victims’ data and demands payment in return for restoring it is fast becoming the most popular way for cyber criminals to make money.

“This is a simple business model based on the principle of selling data to the highest bidder, which is often the person or organisation that owns the data in the first place,” said Hypponen.

F-Security is currently tracking more than 110 different ransomware groups operating around the world and competing for market share.

“Ransomware has become very competitive, with the result of some groups seeking to expand into new markets by translating ransomware campaigns into 26 different languages,” said Hypponen.

Another evolution of ransomware attacks is the shift away from consumers to target enterprises.

“As soon as an infected computer is connected to the corporate network, the attackers enumerate and mount all the file shares the user can access and dynamically set the ransom based on how many files they manage to encrypt on the network,” said Hypponen.

The biggest concern about ransomware for enterprises is that it will stop business operations. With continuity in mind, some enterprises are even setting up bitcoin wallets to be able to pay ransoms quickly and minimise the impact on business continuity.

“This idea of continuity is really backwards, because it does not address the problem,” said Hypponen. “The more enterprises pay these ransoms, the greater and more entrenched this problem will become.”

EDPR and customers data protection

October 20, 2016 By Cyber SecurityNo Comments

We follow on from our Cyber Security Force’s post yesterday about 96% of firms being unprepared for tougher data protection laws.

While businesses grapple to become compliant, they remain out of touch with consumer expectations when it comes to data privacy and security.

Nearly three quarters of businesses do not think an organisation’s privacy track record is a top three consideration for customers when choosing who to do business with, despite customers asking about data security in more than a third of transactions.

Equally concerning, the report said, is the finding that 35% of respondents do not believe their organisation takes an ethical approach to securing and protecting data.

These results show there is a significant disconnect with consumer priorities, the report said, with 88% of European consumers regarding data security as the most important factor when choosing a company with which to do business. In fact, 86% consider it more important than product quality.

Unsurprisingly, the study found that 55% of businesses are not confident they completely meet customers’ data security expectations.

The study also found many businesses have not started working out the necessary organisational and cultural changes they need to make ahead of May 2018.

Some 9% of businesses admitted that all employees are able to access customers’ personal information, while 6% admitted that all staff can access customers’ payment details. Only 14% believe everyone in the organisation has a responsibility to ensure data is protected.

With such wide reaching access to people’s personal information, businesses are underestimating the challenges they will face in managing this in line with the GDPR, the report said.

Under half of those surveyed said managing data ethically is a top priority for their organisation, and less than half again said they would be increasing security training. Only 27% of businesses polled said they are planning to overhaul their approach to security in response to the GDPR.
Technical readiness

The majority of respondents (91%) have concerns about the ability of their organisation to comply with the GDPR, due to factors such as the complexity of processing data correctly in time and costs involved.

Only 28% of IT and business decision makers realise the right to be forgotten is part of GDPR, while 90% of businesses say customers requesting their data be deleted will be a challenge for their organisation.

Only 9% of respondents have already received requests to be forgotten, but 81% believe their customers would exercise their right for data to be deleted, and 60% of businesses do not currently have a system in place that enables them to respond to these requests.

With less than two years before the EU data protection rules come into force, there are 10 key areas businesses need to focus on to ensure they will be compliant.

The European Parliament’s official publication of the General Data Protection Regulation means it will become enforceable on 25 May 2018.

Companies that fail to start planning to deal with the EU’s data protection requirements are in for a real shock, warns the International Association of Information Technology Asset Managers.
The GDPR is about enabling organisations to realise the benefits of the digital era, but it is serious about enforcement for those that do not play in the rules, says UK information commissioner.

Nearly all European businesses unprepared for new data protection laws

October 19, 2016 By Cyber SecurityNo Comments

96% of companies still do not fully understand the European General Data Protection Regulation (GDPR), a survey has revealed.

Lack of consumer and regulatory understanding, combined with low technical and cultural preparedness, represents a major threat to revenue and brand value, according to a Symantec state of privacy report

As a result, 91% of 900 businesses and IT decision makers polled in the UK, France and Germany have concerns about their ability to become compliant by the time the GDPR comes into force on 25 May 2018, according to Symantec’s State of Privacy Report.

The report coincides with a call by the Payment Card Industry Security Standards Council (PCI SSC) for firms to act now to avoid exponentially increased penalties under new European Union (EU) data protection regulations.

UK businesses could face up to £122 billion in penalties for data breaches when new EU legislation comes into effect, the PCI SSC has warned.

The Symantec study also revealed only 22% of businesses consider compliance a top priority in the next two years, despite only 26% of respondents believing their organisation is fully prepared for the GDPR.

Nearly a quarter of those polled said their organisation will not be compliant at all, or will be only partly compliant, by 2018.

Of this group, only a fifth believe it is even possible to become fully compliant with the GDPR, with nearly half believing that while some company departments will be able to comply, but others will not.

This stark lack of confidence in meeting the May 2018 deadline leaves businesses at risk of incurring significant fines, the report said.

These findings show businesses are not only underprepared for the GDPR, they are under preparing,” said Kevin Isaac, senior vice-president, Symantec.

“There is a significant disconnect between how important privacy and security is for consumers, and its priority for businesses. The good news is there’s still time to remedy the situation, but only if firms take immediate action,” he said.

National Cyber Security Centre (NCSC) launched today

October 4, 2016 By Cyber SecurityNo Comments

The National Cyber Security Centre (NCSC) is officially launched and open for business today 4 October 2016.

The government outlined what the NCSC would do, how it would work and who it would work for in May this year, but had not given a precise date for the official opening of the centre until now.

The NCSC will be led by CEO Ciaran Martin, formerly director general of government and industry cyber security at intelligence agency GCHQ, and the technical director will be Ian Levy, formerly technical director of cyber security at GCHQ.

The NCSC will be run from new offices in London as well as from offices near Cheltenham, Gloucestershire.

The primary goal of the NCSC is to simplify the complicated cyber security picture across government that made it difficult for organisations to know who to talk to.

It brings together all the key organisations under a single organisational umbrella to provide better support and bridge the gaps between government, industry and critical national infrastructure.

There were four main goals for the NCSC, which began preparatory work and conducted trials and pilot studies over the summer:

These are to reduce cyber security risk to the UK;
To respond effectively to cyber incidents and reduce the harm they cause to the UK;
To understand the cyber security environment, share knowledge and address systemic vulnerabilities and;
To build the UK’s cyber security capability, providing leadership on key national cyber security issues.

The NCSC has five areas of focus: engagement, strategy and communications, incident management, operations, and technical research and innovation.

In the next six months, the NCSC will test its strategic plan and refine it further based on feedback received.

Yahoo hack effects Sky and BT emails as well

September 26, 2016 By Cyber SecurityNo Comments

The world’s largest hacking of Yahoo also effects BT and Sky email users.

Yahoo wasn’t the tech giant in Silicon Valley that it used to be, but the news that half a billion user details were stolen from it over two years ago in 2014 should still concern everyone.

It now transpires that both BT and Sky used Yahoo’s email system and labelled it as their own. Which is particularly ironic given that Sky’s parent company Fox has had to pay out hundreds of millions to people it had itself hacked it’s customers.

What is even more worrying is customer inertia- that’s because stubborn user behavior and the economics of darknet markets mean the chances of a serious breach at another major internet service increase dramatically with each hack.

The user behavior part is that people like to reuse their passwords—a lot.

One estimate, from Cambridge University’s Security Group, puts password reuse as high as 49%.

That is, we use the same password for every two accounts that require a log-in.

When a big cache of hacked passwords ends up traded on darknet markets, it often gets added to password databases. These databases can be used by corporations to ensure their users don’t use previously published, insecure passwords—or more maliciously by hackers, who will try to find passwords reused on other services.

It’s the equivalent of trying millions of different keys on a particular door, except it’s all automated and can be done in days, as the password cracker Jeremi Gosney has detailed for Ars Technica.

Password reuse and marketplaces for stolen data mean that password databases grow larger and more robust with each major breach. For example, LinkedIn was hacked in 2012 for more than 100 million user accounts. Parts of those stolen credentials wound up in darknet data dumps.

One of those log-ins belonged to a Dropbox employee, who apparently reused a password, allowing a hacker to enter the file-sharing platform’s corporate network. This led to the theft of 70 million Dropbox user passwords, which the company confirmed in August. One massive hack leads to another, forming a daisy-chain of insecurity.

The Yahoo breach is five times the size of the LinkedIn theft. That’s a lot more data to add to password-cracking lists.

The only thing we internet users have going for us now is to hope the “state-sponsored actor” that Yahoo says is behind the hack doesn’t dump the data in public, or sell it for profit. When that happens, we’re due for a password reset.
