An approach to an organization's risk factors (part 3)
In this third and final part of our article series about risk factors, we will examine Human attack factors and Physical factors.
An approach to an organization's risk factors (part 2)
The previous article discussed different procedures and systems that could be invoked in order to mitigate risk. In subsequent parts we will examine areas at risk, starting with Electronic factors.
An approach to an organization's risk factors (part 1)
The aim of this type of initial risk analysis is to identify potentially vulnerable points that may be exploited if they are not sufficiently secured.
Malicious images (codes)
The ease involved in creating QR codes that links to web pages implies that this will be a popular way to facilitate the propagation of malware for mobile devices.
BEAST (Browser Exploit Against SSL/TLS)
A successful attack is not particularly easy to carry out, as it depends on several prerequisites.
The importance of typing correctly
Computers do what they are told. This may result in consequences that are funny as well as dangerous.
Circumventing malware detection
Malware authors continue to pursue delivery mechanisms that can confuse different malware detection systems.
Combating fake antimalware
Coordinated efforts between experts/authorities against cybercriminals seem like the most efficient method for combating cybercriminals. Different experts and authorities are then able to focus on the part of the criminal chain that corresponds to their ability and expertise.
Diversification of attack vectors
Computer systems are becoming increasingly sophisticated and complex with components that are individually computerized. This increases the attack surface for cybercriminals, and represents a challenge for users and the security industry.
Mobile (in)security
The steps that private users and organizations can take to protect themselves, are quite similar in character to protection of traditional computers.
Targeted attacks: More "Bang for the Buck"
Since the cybercriminals seem to shift from randomly directed mass attacks to more focused attacks, the total volume of spam will decrease.
Plug mouse into the computer - be compromised
It is almost impossible to protect completely against a targeted cyberattack against an organization.
The profitable Pay-per-Install ecosystem
We shall in this article focus on the PPI ecosystem and how this is used for malware distribution.
The old dogs are still in learning mode
The web site (usually an infected site) that displays the message checks the browser visiting the site, and displays a warning message similar to the browser's real warning.
Dangerous images
Recent weeks have shown that images are used as a malware spreading technique; particularly images that appear after performing a Google image search.
The RTLO unicode hole - sequence manipulation as an attack vector
Do not rely on any file attachment or file on any device to be safe based on its file name.
Cybercriminals focus on new targets
Users of the operating system Mac OS X have so far been quite safe from malware infections compared to those who have chosen Windows as the operating system platform.
Microsoft's Coordinated Vulnerability Disclosure policy
As one of the largest companies in the software industry, Microsoft's policy will influence the way vulnerabilities are handled.
No access to your data unless...
Blocked access to important information - particularly if adequate backup routines are not in place - may be disastrous for the person who becomes the victim of ransomware.
The PlayStation 3 controversy - Anonymous enters the scene (UPDATED 2011-04-12)
Anonymous characterizes itself as a hive and a nest. One potential issue with such free structures is the potential for different actions that may conflict with each other.
Free music with an unwanted tune
Whenever malware authors find new vehicles to spread their malware, the probability for success increases immensely.
Spam botnet Rustock beheaded
Bots and botnets comprise one of the biggest threats to the Internet and its users. However, recent news report of a success story: beheading the spam botnet Rustock.
Shamelessly exploiting disasters
In previous security articles, we discussed the fact that cybercriminals use big events to spread malware. Not surprisingly - nevertheless disgusting - the recent events in Japan have inspired shameless exploitations by cybercriminals.
Malware targeting the finance sector's customers
In our security article last week, we discussed cybercriminals who targeted financial institutions in an indirect way. However, the major bulk of malware aimed at the finance sector puts the finance sector's customers at peril. One obvious reason is that the average end user's system presumably is less secure than the systems used by the financial sector.
PlayStation 3 security fully compromised
Sony's PlayStation 3 (PS3) has been viewed as one of the most secure gaming devices. Applications and games from other sources than Sony could not be installed and run on PS3, and a firmware update early in 2010 disallowed using other operating systems than the one set up by Sony. All this is now changed.
The year 2010 in a data security retrospective
December is the month to look back on the year that is coming to an end. We will attempt to sum up the situation seen from a security company's point of view. The most significant data security incidents to mention from the year are the sophisticated malware Stuxnet and incidents in the wake of WikiLeaks publication of U.S. embassy cables late November.
The ultimate surfing challenge: Avoiding web sites with malicious content
Some years ago it was an established "fact" that a computer could not be infected by malicious software by visiting a web page. But technology evolves quickly and some facts may change when new technology emerges. These days web pages are perhaps the most used propagation vector for malware.
Malicous cold calls with high success probability
According to a posting 15 November on the blog belonging to the UK based organization Get Safe Online, one in four UK web users have been targeted by so-called cold calls.
Communication consolidation or security nightmare
In recent months there have been lots of rumors about the upcoming email system closely integrated with Facebook. More detaileds about this have recently been disclosed by Facebook, and we will examine some aspects of the new offerings.
Safe crime
We have previously advocated the view that endpoint security is just one of several tools needed to accomplish secure environments. This article will examine one particular threat against the Internet community and discuss how it may be overcome.
Firesheep - an eye-opener or a tool for criminals
A little more than one week ago a new extension to the Firefox web browser was published. And it got attention for sure!
Hey, your computer is infected!
In a press release 25 October the Dutch High Tech Crime Team (THTC) of the National Crime Squad announced a successful takedown of a major botnet. 143 malicious computer servers were taken down from the internet resulting from collaboration with a Dutch hosting provider, the Dutch Forensic Institute (NFI), the internet security company Fox IT and GOVCERT.NL and the Dutch computer emergency response team.
Are security products losing the battle?
The product testing organization NSS Labs has recently published its test report for the 3rd quarter 2010 - test results for 11 antimalware products for consumers. The most interesting finding from this report is that the security products' performance have deteriorated compared to last year. In this security article we shall examine the implications of this.
Man-in-the-middle goes Mobile
The term Man-in-the-middle in a security context refers to an attack where someone/-thing is inserted between two endpoints and intercepts the communication between those. The intent is usually to obtain information and use this for illegitimate purposes. Recently the term Man-in-the-mobile, abbreviated as Mitmo, emerged.
A new generation of malware
Computer software evolves, and popular interpretation is to introduce new generations whenever fundamental changes arrive. If one looks at malware in the same manner, one may also classify different types into various generations.
DDoS war
Last week in our article "Ways to use botnets", we discussed among other issues, botnets for hire. One example we mentioned in our article was the company Aiplex Software, which was hired to try stop illegal distribution of copyrighted material.
Ways to use botnets
This article will not go in depth with regard to how the different botnets function technically. We shall rather examine some of the ways botnets may be used, study one successful method used for fighting this threat, and finally discuss the idea of botnets used for benign purposes.
Old dogs learn new tricks
Fake antimalware software has become an increasing problem for end users and corporations. The creators of these rogue applications are able to earn easy money and are constantly searching for new ways to exploit their victims. A new technique has recently been seen. We shall look at this in more detail in this security article, and attempt to point to some general considerations regarding this type of software and malware in general.
A plethora of malware for mobile phones to be expected soon (?)
In later years dangerous malicious software for mobile phones and other handheld devices has been predicted and expected by several analysts. Norman, however has traditionally been among those more reluctant in predicting that the explosion of if malicious software for mobile devices is imminent. In retrospective it seems safe to say that our view has proven correct (so far).
Exploits for .LNK vulnerability are growing fast (UPDATED 3 August)
Norman releases generic protection against the .LNK vulnerability for customers running NPRO 7.20. The automatic scanner will stop attempts to exploit the .LNK vulnerability, thus also proactively protect customers against both known and unknown malware. Customers running Norman Network Protection will also be protected against known malware using this exploit if executed from a network share.
Første halvår 2010 - oversikt over sikkerhetshendelser
Vi vil i denne rapporten om sikkerhetshendelser i første halvår 2010, gå gjennom en del forskjellige saker og trender. Vi vil fokusere på dem Norman ser som mest betydningsfulle i de siste seks måneder.
Utlevere informasjon om sårbarheter? Ja/Nei/Når?
Forrige uke offentliggjorde en forsker fra Google, Tavis Ormandy, informasjon om og utnyttelselsekode for en ny sårbarhet i Microsofts kundestøttesenter.
Reflections on the PDF vulnerability
Earlier this month we wrote about a vulnerability in the PDF specification that could be utilized to run malicious programs embedded in a PDF file. Proof-of-concept code was published, and it was expected that real-life malware that used this technique might appear soon.
Subscription to malware testing
The title may imply that this article is about subscription services for email checking, like Norman Online Protection. Rather not! This time we shall examine yet another way that criminal activity imitates legitimate business.
Scary technique utilizing functionality in the PDF specification
Exploitation of how applications handle files in the Portable Document Format (PDF) is one of the most used techniques to successfully create malicious software. Usually this is accomplished by utilizing vulnerabilities in the applications used to read PDF documents, like the very popular free program, Adobe Reader.
Cyber crime imitates legitimate business
We have earlier discussed the fact that cyber criminals are getting increasingly sophisticated in their attempts to succeed in obtaining illegitimate gain. We will now look into an example of how illegitimate businesses imitate legitimate.
Handling an infected computer as an infected human being
The RSA Conferences are among of the most important annual security conferences. This year's US conference was held in San Francisco 1 - 5 March. One of the speakers was Microsoft's Scott Charney, Corporate Vice President Trustworthy Computing. His speech covered several interesting topics, of which we will discuss one: the ability, usefulness and implications of treating infected computers in a similar manner as infected human beings.
Code injection
Code injection is a protection mechanism used by malware in order to avoid detection. The injector stores the malware as an encrypted resource, which it decrypts and injects into a running process. The injector may also contain various checks for virtual machines and system tools in order to hinder analysis.
W32/Zimuse
Zimuse is a family of worms that performs destructive overwrites of the Master Boot Record of disk drives on the infected system. If the current system date and time matches certain conditions, the worm overwrites the Master Boot Record of available drives with its own data. The worm will also try to delete some of the important files of the Windows Operating system. The file is run-time compressed using PECompact arrives on the system either as a standalone file (possibly from a malicious download or e-mail) or by infected removable devices (e.g., USB sticks).
Oppsummering av 2009 - spådommer for det kommende året
Desember er måneden for å se tilbake på året som nærmer seg slutt, og vi vil forsøke å oppsummere situasjonen sett fra et sikkerhetsselskaps perspektiv. Den mest betydningsfulle observasjonen hva gjelder aktivitetene til ondsinnet programvare (malware), er at forskjellige typer sosiale nettverk ble et hovedmål for forfatterne av ondsinnet programvare.
Holidays - preferred season for children and ...criminals
Major events, happenings and in general all kind of things that create much notice, also leave in their wake a stream of malicious software.
Plug-ins to applications - a ripened target for malware
In several security articles we have discussed the fact that new media and communication devices are successful vehicles for malware propagation. This time we will examine a type of application, which has not been focused upon - (presumably) neither by the malware authors yet, nor by commentators.
Malicious identity production
Identity theft is a term, which has become familiar during the latest years. More exotic - until recently - has been identity production with malicious intent. A new version of Koobface does exactly that - automatically.
Lots of free email accounts compromised
Earlier this month multiple tens of thousand passwords to free email accounts from Microsoft (Hotmail), Google (GMail) and Yahoo were compromised.
Developing malware using the open source approach
Open source development is an approach to the design, development, and distribution of software, offering practical accessibility to the software’s source code. The open source approach claims to have several benefits and advantages compared to a more closed approach to source development.
Dedicated servers as parts of a botnet
In the security article this week we will discuss using a particular type of computers - dedicated servers - as part of a botnet.
Hacker tool? Security application? Or both?
Nmap (Network Mapper) is perhaps the most famous and used hacker tool that exists. Since its introduction in autumn 1997, this tool written by the pseudonym Fyodor (real name Gordon Lyon), has helped numerous hackers gathering valuable information about their targets. This summer Nmap version 5 was released. According to Insecure.org, this is supposed to be "the most important Nmap release since 1997".
Compromised telephone conversations
Listening in to telephone conversations is traditionally associated with initiatives from national security agencies / police organizations with vast resources, or shady private detectives. This may not be the case any more if the person or persons under surveillance use a particular system for telephone calls.
Malware in applications - a special problem
Recently Norman's senior virus analyst Snorre Fagerland wrote about the malware W32/Induc.A in our security blog. This is a virus which infects the programming language Delphi. The result is that applications that are created with an infected Delphi environment are infected themselves. This has interesting implications as we shall see.
Another way to use Twitter
We have discussed Twitter in a few security articles this year. This time however, we shall focus on a new usage of this social network: Twitter as an element in a malicious setup.
Attack on major social network sites to stop ONE person
Last week the media was flooded by information about an attack on social networking sites like Twitter, LiveJournal and Facebook, allegedly with the intent to stop one Georgian blogger.

The short URL functionality obviously has its merits. However, there are shortcomings and security issues that make the system in itself less secure than desired.
Unlimited supply of money...
This security article's title may look like the intro to a fairytale told to by a criminal to her child. However, a family of malicious software (malware) that has appeared this year seems to make this fairytale come true for some…
The Internet's challenges recognized at highest level
Security organizations of different types have notified about perils involved for individuals as well as corporations, and the public sector in using the Internet. Unfortunately these warnings have often not been recognized with the sincerity they deserve. President Obama's speech is therefore a welcomed acknowledgement from the highest political level.
You're bad. No, I'm not!
The vendors of security software have the following simple task: Detect and remove as much malicious software as possible without erroneously defining benign software as malware. Unfortunately, this is not as simple as it seems.
Domain name registration - a malware spreading vector
Another use of web servers has been on the rise as malware spreaders. This approach exploits popular terms to trick users to visit web sites that are by intent malicious.
GhostNet - a real espionage network
This week started with significant media attention about a report, which showed that several computers owned by governments and international organizations were compromized. This includes several embassies world-wide and a NATO computer.
Hot stuff: Exploitable routers - a flash of the whole iceberg
A new type of malicious software has recently been getting some media attention. The most interesting part of this is the fact that the malware's targets are not traditional computers. Rather does this malware attack different types of devices, namely routers and modems.
Information about "most popular" threats - ATLAS
ATLAS views computer attacks from a global perspective and helps users predict future network attacks. It does this by analyzing data gathered from a variety of sensors.
Social engineering with a virtual twist
Social engineering in several forms has been discussed in numerous of our security articles. This time, we shall discuss it from a different angle - the traditional one, with a quite clever new twist.
A security issue? Oops - not!
Security organizations are in constant battle with malware authors, trying to protect end users from being infected by "bad stuff". As we shall see in this week's security article, some undesirable side effects unfortunately occur from time to time.
DOS events
The title of this week's security information does not refer to the celebration of an anniversary for the legacy PC operating system DOS. It is another of those neologisms that pop up continuously.
"We told you so" - hindsight is usually correct
The need to apply security patches to operating systems and applications has been discussed several times in our security articles. Recent events show that this is a caution that cannot be repeated too often.
Mobile phone threats - hype or (finally) truth?
So far there has been no really dangerous malicious software targeting mobile phones. The New Year 2009 started with a new, interesting threat to mobile phones, which may change this picture.
Christmas time - a season to enjoy AND fear
Major events, happenings and in general all kind of things that create much notice, also leave in their wake a stream of malicious software.
Program downloads from the Internet - a risky activity
The Internet offers a cornucopia of applications, movies, pictures, text - everything digital that can be imagined (and some not!). Navigating this is difficult and can even be hazardous in several ways.
Internet gaming - new opportunities for the (shady) visionary
The use of money involved in online gaming has traditionally been only as an entrance fee to buy the game itself (if it is not free). This no longer holds true.
Fighting malware on two ends
Recently we have seen that some of the major players on "the dark side" of the Internet community have been removed from the Internet. Malicious activity dropped instantly - and by an amazingly significant quantity.
Ghosts from the past resurface through USB sticks
The increasing use of USB sticks and their storage capacity constitute major security issues. Problems that were dominant with floppy disks resurface.
Security patches - an additional security issue
There are some issues with security patches that in fact may render certain users more vulnerable. This apparent contradiction will be examined in this article.
Facebook - an increasingly popular spreading vector for malware
Customized malware, which utilizes and targets the Facebook community, is emerging. Several reports about different types of malware are appearing, and more are certain to come.
Clickjacking - a new danger or an innovational new name?
A few weeks ago a new name started circulating in security writings - "clickjacking". Security organizations as well as web-based news agencies reported this as a major, new threat.
