Round-up: Top posts of 2015

2015 is almost over and we have been pleased and delighted to welcome many new followers and contributors to the Advent IM Holistic Security blog. It’s hard to wade through all the content but we thought it would be nice to present you with a list of some of our most popular posts this year, by month. (This is based upon what people read and not necessarily when they were published.)

jAN 2015In January, we warned you to watch out for phishing emails if you had nice shiny new devices for Christmas. We were recognised as Cyber Security Solution Suppliers to Her Majesty’s Government and we enjoyed a visit from The Right Honourable Francis Maude to talk all things CyberSec.

 

In FFEB 2015ebruary, we had a visit from James Morrison MP to talk about how cyber attacks affect local and national businesses, we launched Whitepaper on CCTV in schools and discussed the key ‘watch-outs’ in off-shoring data in relation to Data Protection

 

MAR 2015In March, we were exhibiting and speaking at the Security & Policing Event at Farnborough (we will be at the next one too, watch this space for details!) Mike Gillespie’s quote in The Sunday Times, talking about SMEs and Cyber Security back in 2014 suddenly shot back up the blog statistics, as people explored some of our older posts.

 

april 2015In April, law firms were in the sights of the ICO and we blogged about it and people looking for Senior Information Risk Owner Training found their way to the blog. Of course, if you do want to book training you need to go via the website

mAY 2015

In May, Ransomware was on everyone’s radar, including ours.  A lot of readers also sought out an old post on mapping the control changes in ISO 27001 2005 vs. 2013 and we were glad they found our tool to help them with this. We think that more businesses will want to think about this standard in 2016 as security awareness continues to grow and the common sense reveals the huge commercial benefits.

JUN 2015In June, the changes to EU Data Protection regulations had a lot of people talking. Dale Penn gave a no nonsense post, explaining what it meant and it was very well received. We had a Risk Assessment methodology post from Del Brazil, talking, Attack Trees. A post that was also very well read came from Julia McCarron who discussed the risk in continuing to run Windows XP

JUL 2015In July, Social Engineering was a key topic and one of our blog posts was very well visited, The Best Attack Exploit by Dale Penn is still receiving visits. Dale also wrote about hacking Planes, Trains and Automobiles, with clarity, as well as the coverage this kind of hacking was receiving.

AUG 2015In August, we heard about Hacking Team being hacked and it revealed some very risky security behaviour. Dale Penn wrote about this event and other security specialists being targeted. In August, a very old blog post started to get some traffic again as people wanted to read about secure destruction of hard drives and a guest post from Malcolm Charnock got hoisted back into the charts.

SEP 2015In September, TOR was in the press sometimes as a hero, but usually as a villain…well perhaps not a villain but certainly suspicious. We tried to throw some light on what TOR is for the uninitiated and explain why and how it is deployed by a variety of users. It came courtesy of Del Brazil. Another very old post on USBs also got raised from the archive – The Ubiquitous Security Breach.

OCT 2015In October, traffic to the blog doubled and we welcomed many more new readers. All of the posts mentioned here were read but far and away the winner was Crime of Our Generation from Chris Cope, talking about TalkTalk’s disastrous breach.  Marks and Spencers were discussed by Julia McCarron in light of their own security failure. Attack of the Drones discussed a variety of drone-related areas, uses and unintended consequences. A nuclear power plant worker was found researching bomb making on a laptop at work and the EU Safe Harbour agreement melted away. It was a very busy month…

NOV 2015In November, The Bank Of England expressed some firm opinion on cyber security requirements in the Financial sector. Morrisons staff took to the courts to sue over the data breach that exposed their personal information. Australia jailed a former junior bureaucrat who leaked defense material onto the notorious 4Chan website. The previous posts on TalkTalk, M&S, BoE, Safe Harbout and EU DP Regulations were also extensively read in November.

dEC 2015And finally, December…Well the Advent Advent Calendar has been a festive fixture for three years now so we had to make sure it was included and it has, as always,  been well trampled and shared. We also added a new festive bit of fun in the form of the 12 Days of a Phishy Christmas and some Security Predictions from the team for 2016. Why would anyone hack the weather? was a look at how attacks can be intended for other parts of a supply chain. Finally TalkTalk popped up in the news and a conversation again, as it emerged that Police had advised the firm not to discuss their breach.

TalkTalk advised not to talktalk about their breach?

According the International Business Times, the Metropolitan Police advised TalkTalk not to discuss their breach. (you can read the article here)

Here, in conversation on the topic , is Advent IM Directors, Julia McCarron and Mike Gillespie and Security Consultant, Chris Cope.

“This is interesting as it shows the 2 different priorities at work.  For the police, the key aim is to catch the perpetrator.  This often means allowing an attacker to continue so they can be monitored on the network and their activities logged and traced without causing them to suspect that they are being monitored in such a way.  The Cuckoos Egg details how the Lawrence Berkeley Lab famously did just this in response to a hack of their system.  However, TalkTalk have a duty of care to their customers.  If personal information could be used to steal money, then they must weigh up the advice from the police, along with the potential impact of not publicising this attack on ordinary people. Its easy to see how a CEO can be caught in between trying to help the police, but also attempting to limit the damage to their customers.  Ultimately it’s a difficult decision, but one that could be made easier with correct forensic planning, i.e. working out how to preserve evidence of an attack, which can be provided to the police, whilst ensuring that normal services continue and customers are warned.  Making these decisions during an actual incident will only make a stressful time even more so; far better to plan ahead.”

Julia McCarron

Julia McCarron

“Totally agree … something to add…

This is a classic case of being stuck between a rock and a hard place. As Chris quite rightly says two different objectives were at play here and each had its merits. Ultimately it was a difficult decision to make but you can’t knock TalkTalk for once, as it appears to have been an informed one.

Whilst I also agree with Chris on the forensics front, experience has shown us that staff need to be aware of what to do ‘forensically’ in the event of an incident and this is often where the process falls down. Because such incidents are usually rare, the chain of evidence is often corrupted unintentionally because no-one knows what to do, or it’s no longer available due to the time lag in occurrence and detection.

Intrusion detection systems along with other technological measures will be an asset in reducing that time lag but key to success is scenario training. In the same way as we are seeing Phishing tests becoming the norm, especially in customer facing organisations like TalkTalk, is there a place for forensic readiness testing to ensure staff know what to do when a security attack occurs? Then vital evidence is at hand when hacks like this occur and the force awakens.”

Mike Gillespie

“Totally agree, Chris. It’s a tough balance but the protection of the consumer should always come first in my opinion.

Forensic readiness planning is key and continues to be a weak area for many organisations – linking this with an effective communication plan is vital – and as with any plan it needs to be properly tested and exercised…….as do all aspects of cyber response…..using appropriate scenario based exercises.

All of this should be designed to drive continual improvement and to ensure our cyber response evolves to meet emerging threats.”

Security Predictions for 2016

As 2015 draws to a close, we asked the Advent IM Staff to ponder the challenges for next year. 2015 saw some huge data and security fumbles and millions of people had their personal information exposed as hack after hack revealed not only how much this activity is on the increase, but also how  the security posture of some businesses is clearly unfit for purpose.

Over to the team…

Dale Penn – I predict that with the recent introduction of Apple Pay and Google’s Android Pay we will see a large upswing in mobile device targeted attacks trying to get at our bank accounts.

Del Brazil – Attacks will be pushing in from the Siberian peninsular coupled with additional attacks from the orient- this will bring a chill to the spines of organisations.  These attacks are likely to be followed by sweeping phishing scams from the African continent.  There is also the likelihood that attacks towards HMG assets from Middle Eastern warm fronts will further identify/expose weaknesses within organisations. Closer to home is the ever increasing cold chill developing within organisations as the realisation that the threat from insiders is on the rise. In summary it’s going to be a mixed bag of events for a number of wide ranging organisations. However on the whole, as long as organisations grab their security blanket they will be best placed to ward off the majority of attacks.

Chris Cope – If 2015 saw a significant number of high profile information security breaches, then expect 2016 to be more of the same.  Attackers are getting cleverer at exploiting weaknesses; most notably those presented by people.  I confidently predict that a significant number of incidents in 2016 will feature poor security decisions made by employees.  I also predict a significant challenge for many organisation which hold personal data.  The forthcoming EU regulation on data protection will provide significant challenges on the protection of personal information of EU citizens.  With a significant increase in financial sanctions highly likely, the importance of safeguarding personal data has increased dramatically for any organisation, even those who were not challenged by the penalties previously awarded by the Information Commissioners Office (ICO).  Could this be the start of a wider regulatory drive to improve information security – probably not, at least not yet. Finally, with continuing uncertainty across key areas of the globe, particularly the Middle East, we will also see more examples of ‘cyber warfare’ as this nascent capability continues to be exploited.  This will lead to a flurry of reports on how cyber war is about to doom us all or is irrelevant (depending on one’s viewpoint); surely an opportunity to educate the wider populace, and key decision makers, on what information security, and its potential consequences, could actually mean?

Mark Jones – I predict…

  • Cloud security becomes even more important as more and more businesses move services there – more demand for ISO27017
  • Related to the above, more Data Centre Security certifications due to contractor (customer) requirements
  • More BYOD-related security incidents with more mobile malware found on all platforms with China the main source – mobile payments being a prime target
  • Cyber Essentials leads to more demand for ISO27001 certifications from SMEs
  • Privileged insider remains the main Threat Source & Actor
  • More incidents relating to online cyber-extortion / ransomware
  • With increasing demand for infosec specialists and/or DPOs organisations will find it more difficult to recruit than ever
  • More incidents relating to the Internet of Things – smart devices such as drones falling out of the sky causing harm; more car computers hacked resulting in more car theft

Ellie Hurst – Media, and Marcomms Manager – I predict the growth of ransomware  in business.  Ransomware, is mainly (though not exclusively) spread by phishing and given the success of phishing as an attack vector and that one in four UK employees don’t even know what it is (OnePoll for PhishMe), I think it will continue to be the most likely form of ransomware proliferation. Of course, it can also be spread by use of inappropriate websites and so businesses that do not have, or enforce a policy or exercise restrictions in this area, will also find themselves victims of this cynical exploit.

A word from our Directors…

Julia McCarron

Julia McCarron – Advent IM Operations Director – I predict a RIOT – Risks from Information Orientated Threats.

Mike Gillespie – Advent IM Managing Director – I predict an escalation in the number and severity of data breach in the coming year. Recent failures, such as TalkTalk, VTech and Wetherspoons highlight that many businesses still do not appreciate the value of the information assets they hold and manage. Business needs to increase self-awareness and looking at the Wetherspoons breach, ask the difficult question, “Should we still be holding this data?”

I think the buzz phrase for 2016 will be Information Asset Owners and if you want to know more about that, then you will have to keep an eye on what Advent IM is doing in 2016!

Why would anyone want to hack the weather?

A review of the news of the BoM attack  from Security Consultant, Chris Cope.

Or more precisely, why would anyone want to hack the Australian met office?  Well, its happened and officials are quick to announce that the damage will take millions of dollars to fix and that China was responsible for the hack.  Its not the first time that allegations have been made against Chinese hackers and, with the information available, it is pure speculation for non-official sources to speculate on how accurate the Australian allegation is.  But what is interesting is the close links between the Australian met office and the Ministry of Defence.  The nature of the links aren’t specified, but for an attacker looking to infiltrate the Australian Ministry of Defence, the obvious ways in are more than likely to be heavily protected.  But what about subsidiaries?  Could the Australian met office represent a weak link?  In this case, perhaps not as the intrusion was detected but there remains a lesson here for all companies.  Increasingly, outsourcing is becoming more common.  Services that organisations don’t want to deliver themselves are passed on to a service provider.  So, whilst we might be content that the security measures in place for our company are robust, can we say the same about those third parties that we connect to?  What assurances have been carried out, do contracts cover security consideration, are those connections monitored and is there a joined up incident reporting procedure?  All of these are valid questions and ones that are increasingly important in our interconnected world.  If you don’t know the answers to these questions, perhaps its time to find out, before a trusted partner becomes your Achilles Heel.

Trident vulnerable to hacking?

By Julia McCarron with contribution from Chris Cope.

There have been a number of press stories in the last few days that could have us searching for our 3 pronged spears to protect these shores because, if the news is to be believed, the missile version of Trident could be rendered useless or obsolete from a cyber-hack.

I don’t know about you but I viewed these articles with some skepticism as I can’t believe that the MOD and Government haven’t thought to test the technical vulnerabilities of such a critical system before now, especially one with such far reaching consequences if it were breached?

As I understand it from those who have knowledge of MOD workings, all military systems, including Trident and its associated communications networks, are assured via the Defence Information Assurance Services (DIAS) Accreditors.  This assurance process takes into account the likely threats and resulting risks that apply to those systems, including hacking and other forms of cyber-attack.  There is a stringent policy of assessment and review for all major systems, and Trident will be one of the most assured systems due to its importance.  Clearly, though details of this assurance are highly unlikely to ever be released into the public domain; information on risks and counter measures taken against them will be very closely guarded. And I would hope so too!

The MOD will employ a number of safeguards to protect its most important systems.  Many of these will be familiar to the wider information security field and it’s no surprise that ISO27001 features heavily.  The greater the risks to the system, and the more critical it is, the more stringent the controls in place. Many high level MOD systems are effectively air-gapped and have no connection to the internet, even via a controlled gateway. That means they are effectively isolated from other communications networks, even the authorised users are heavily constrained in what they can and cannot do; use of mobile media for example is highly regulated.  Given Trident’s role as a potential counter-strike weapon, the communications to the deployed vessels receive very careful attention.  Not only will there be good level of assurance against the normal range of attacks, but there will be significant redundancy in place, just in case one fails.  Trident is carried by the Vanguard class submarine, which is designed to operate virtually undetected.  Commanders of these vessels have clear direction from the Prime Minister on what to do if there is evidence of a nuclear attack and all communication from the political leadership in the UK fails.

The comments made by a former Defence Secretary about potential vulnerabilities around the Trident system make interesting reading in light of recent concerns over cyber-attack, but the timing of these comments is telling. The House of Commons is due to vote on the future of the UK’s nuclear deterrent … there I go being skeptical again but as my hero Leroy Jethro Gibbs often says, Rule 39# There’s no such thing as a coincidence…

Email Insecurity

At Symbol

This time of year, there is an upsurge in phishing and other malicious emails for us to contend with. From phony delivery notices to hoax PayPal problem emails, our inboxes are awash with attempts to invade, defraud and otherwise cause us chaos or loss. So the news that people are not taking the threat from email seriously after all the years of phish and spam, is worrying to say the least. Advent IM Security Consultant, Dale Penn, takes a look at the facts.

For far too many people, email security isn’t an issue until it suddenly is. Often, people won’t take threats against email seriously, believing that data breaches only happen to large companies as these are the only breaches that are reported in the news.

Alternatively, companies tend assume that email security is just something that’s already being taken care of as they have purchased the most up to date  technical defences such as anti-virus firewalls, Data loss prevention software etc etc, and it’s true that these can help in a layered approach however one large piece missing from the puzzle is education and awareness.

SC magazine reports that 70% of Brits don’t think that email is a potential cyber threat. And almost half admit opening non work related or personal emails at work.

Corporate Email Vulnerabilities

Bring Your Own Device (BYOD)

This refers to the practice of employees to bringing personally owned mobile devices (laptops, tablets, and smart phones) to their workplace, and to using those devices to access privileged company information and applications.  This corporate ‘bring your own device’ trend is on the rise, according to a new study.

Ovum’s 2013 Multi-Market BYOD Employee Survey found that nearly 70% of employees who own a smartphone or tablet choose to use it to access corporate data.

The study surveyed 4,371 consumers from 19 different countries who were employed full-time in an organisation with over 50 employees.

Computer bugs red greyThe study has discovered that 68.8% of smartphone-owning employees bring their own smartphone to work, and 15.4% of these do so without the IT department’s knowledge. Furthermore, 20.9% do so in-spite of a BYOD policy.

These statistics are quite alarming as uncontrolled devices accessing corporate information represent a significant vulnerability.

Uploading to Personal Email account or Cloud Account

It doesn’t matter how strong your security standards are, or how much money you’ve dumped into the fanciest, most secure cloud storage systems, often employees won’t use them preferring to bypass red tape and send the information to uncontrolled home accounts therefore bypassing any company security.

Risk - Profit and LossWe’d all like to think that those that hold upper management positions in our businesses have higher standards, especially when it comes to security, but the statistics don’t lie. In a Stroz Friedberg survey, almost three-quarters of office workers admitted to uploading their business files to personal accounts and senior managers were even worse, with 87% of them failing to use their company’s servers to store sensitive company documents.

Conclusion

The fact of the matter is that the general security culture of the UK is not as it should be. The public in general (and many organisations) are unaware of, or not interested in applying, the most basic security principles to protect their personal information

Recognising this culture is the first step in treating it. Individuals still treat cyber-attacks with a degree of separation and the view that “it will never happen to them”.  Few people realise that a cyber-attack could potentially be as invasive and disruptive as a physical home invasion. Few people leave their house without taking appropriate security steps. We need to introduce awareness to the masses and embed the culture that has them locking there cyber door as well as the ones at home.

Top email Security tips

  1. Share your e-mail address with only trusted sources.
  2. Be careful when opening attachments and downloading files from friends and family or accepting unknown e-mails.
  3. Be smart when using Instant Messaging (IM) programs. Never accept stranger into your IM groups and never transmit personal information
  4. Watch out for phishing scams. Never click on active links unless you know the source of the email is legitimate.
  5. Do not reply to spam e-mail.
  6. Create a complex e-mail address as they are harder for hackers to auto generate.
  7. Create smart and strong passwords using more than 6 characters, upper and lower case, numbers and special characters i.e. £Ma1l5af3

CRIME OF OUR GENERATION – A Look at the TalkTalk Breach

A review from Advent IM Security Consultant, Chris Cope.

TalkTalkThe TalkTalk hack has left another major UK business reeling from a cyber attack and customers angry as, once again, there is a possibility that sensitive information is now in the public domain.  The telecommunications company decided to take its own website offline on Wednesday following the presence of unusual traffic, with a ‘Russian Islamist’ hacking group taking responsibility and the Metropolitan Police’s Cyber Crime unit now investigating. Detail on precisely how the attack took place are not yet publicly available, but there are some points that are immediately apparent.

Customer security.  The BBC is reporting that personal information and bank account details may have been stored in an unencrypted format and are now available to hacker groups.  Some TalkTalk customers have complained about hoax communications already; it is likely that this is just the start. Customers will need to rely on Talk Talk to identify precisely which customers are affected, but in the interim they must monitor their bank accounts closely.  Any suspicious activity must be reported to their bank immediately as potential fraud.  When the Talk Talk website becomes accessible again, customers should immediately change their passwords, taking care to avoid passwords which are easily guessable.

Undoubtedly this is the crime of our generation as more and more cyber attacks are reported.  But organisations should not despair, it is perfectly possible to reduce the risk from cyber attack by following the basic security precautions contained with ISO27001.  These can be applied to any organisation, large or small.  From what we know of the attack already, there are some specific controls from that standard which become immediately apparent:

  • Use of encryption. Many networks are designed to be hard on the outside, but soft on the inside.  Once an attacker gain access into the network, they can wreak havoc.  The use of encryption is not the solution to all threats, but encrypting sensitive information is an important consideration.  This will not prevent the initial attack, but the impact of a breach is hugely reduced.  Its also a practical option that the Information Commissioners Office would deem as reasonable, and its absence may be difficult to justify during any follow on investigation.  A good standard of encryption will make personal data unreadable to an attacker and at the very least will buy time for customers to make any changes to their account information they deem necessary.
  • In February of this year, TalkTalk reported that a third-party contractor, based in India, that had legitimate access to its customer accounts had been involved in a data breach.  The use of suppliers is wide spread and many organisations now off-shore certain practices for sound business reasons.  But, devolving the process does not devolve the responsibility and organisations must make sure that their suppliers follow a suitable set of security controls that is consistent with their own.  Included in this suit of controls relating to suppliers is the right to audit supplier activities and a linked up incident management reporting structure.  As further details on this incident emerge, it will be intriguing to discover how much Talk Talk knew of that incident and what steps they took to prevent follow on attacks against their own network.  No matter how secure a network may be, authorised connections from trusted third parties remain a very attractive exploit and they must be managed accordingly.
  • The use of defensive monitoring will not prevent an attack, but it can help to radically reduce the impact.  TalkTalk took the decision to take their services off line following the detection of unusual behaviour within their network. This is a brave call and how much that will cost them in terms of financial or reputational impact is yet to be established.  However, just how much worse could it have been without such monitoring?  What if the first indication of the attack was when personal information was being publicly sold, and exploited?  There is a cost to effective defensive monitoring, but it is a cost often worth paying in order to lessen the eventual impact of a breach.

As the list of cyber attacks in 2015 grows again, and shows no sign of tailing off any time soon, organisations must look to their own defenses.  The threat is varied and very real.  Cyber Crime is here to stay, but why make it easy for criminals to succeed?  There are steps that can be taken to reduce the risks of compromise and the impact following an incident.  Customers are now expecting higher levels of cyber security, if organisations wish to maintain their reputation, they should look to deliver it.
