Characteristics of data-stealing malware

Does not leave traces of the event
  • The malware is typically stored in a cache that is routinely flushed
  • The malware may be installed via a drive-by-download process
  • The website hosting the malware as well as the malware is generally temporary or rogue
Frequently changes and extends its functions
  • It is difficult for antivirus software to detect final payload attributes due to the combinations of malware components
  • The malware uses multiple file encryption levels
Thwarts Intrusion Detection Systems (IDS) after successful installation
  • There are no perceivable network anomalies
  • The malware hides in web traffic
  • The malware is stealthier in terms of traffic and resource use
Thwarts disk encryption
  • Data is stolen during decryption and display
  • The malware can record keystrokes, passwords, and screenshots
Thwarts Data Loss Prevention (DLP)
  • Leakage protection hinges on metadata tagging, not everything is tagged
  • Miscreants can use encryption to port data

Examples of data-stealing malware

Vulnerability to malware

In this context, as throughout, it should be borne in mind that the “system” under attack may be of various types, e.g. a single computer and operating system, a network or an application.
Various factors make a system more vulnerable to malware:
  • Homogeneity – e.g. when all computers in a network run the same OS, upon exploiting one, one can exploit them all.
  • Defects – malware leveraging defects in the OS design.
  • Unconfirmed code – code from a floppy disk, CD-ROM or USB device may be executed without the user’s agreement.
  • Over-privileged users – some systems allow all users to modify their internal structures.
  • Over-privileged code – some systems allow code executed by a user to access all rights of that user.
An oft-cited cause of vulnerability of networks is homogeneity or software monoculture.[14] .For example, Microsoft Windows or Apple Mac have such a large share of the market that concentrating on either could enable a cracker to subvert a large number of systems, but any total monoculture is a problem.^ No, this is a clear example of a monopoly creating a market repairing broken Windows.

Instead, introducing inhomogeneity (diversity), purely for the sake of robustness, could increase short-term costs for training and maintenance. .However, having a few diverse nodes would deter total shutdown of the network, and allow those nodes to help with recovery of the infected nodes.^ Cronk I would recomend for the safety of your wallet to not allow the sons computer on your network period without a format and install of his computer.
  • Malware risk from Limewire music? - dslreports.com 28 January 2010 1:23 UTC www.dslreports.com [Source type: General]

Such separate, functional redundancy would avoid the cost of a total shutdown, would avoid homogeneity as the problem of "all eggs in one basket".
.Most systems contain bugs, or loopholes, which may be exploited by malware.^ Malware is not the same as defective software, that is, software which has a legitimate purpose but contains harmful bugs.

^ In most cases, the web sites that infect your system with malware are not intentionally doing so and are often unaware that their web servers have been compromised.

.A typical example is the buffer-overrun weakness, in which an interface designed to store data, in a small area of memory, allows the caller to supply more data than will fit.^ What SEO areas are you weak and strong in, and give examples of both.

This extra data then overwrites the interface's own executable structure (past the end of the buffer and other data). .In this manner, malware can force the system to execute malicious code, by replacing legitimate code with its own payload of instructions (or data values) copied into live memory, outside the buffer area.^ Malware is designed to execute on a system.

In the cryptoviral extortion attack, the virus hybrid encrypts plaintext data on the victim's machine using the randomly generated IV and SK. The IV+SK are then encrypted using the virus writer's public key. In theory the victim must negotiate with the virus writer to get the IV+SK back in order to decrypt the ciphertext (assuming there are no backups). .Analysis of the virus reveals the public key, not the IV and SK needed for decryption, or the private key needed to recover the IV and SK.

Melissa used word documents to shield itself, but had a weakness when it came to certain word programs such as Word 95. Mailing itself was also limited to Microsoft outlook 97/98 and was unable to achieve sending itself through Microsoft Outlook Express. It was the macros in word that maid the worm possible. When you receive the original worm through email this is what it shows you:
From: <name of the infected sender>
Subject: Important message from <name of sender>
To: <The recipients, from the 50 names>
Attachment: LIST.DOC
Body: Here is that document you asked for ... don't show anyone else ;-)
.From there it was changed to Melissa.I/Empirical, to Melissa.O, Melissa.U, Melissa.V, Melissa.W and lastly Melissa.AO. Most of them show differences between each other with the same basics, but Melissa.A (the original) and Melissa.W are believed to be the same.^ That way he'll be on his own network, you'll be in a different subnet, and there's no way for malware or any other exploit fo traverse the subnets.

Virus

Trojan horse

What’s a Trojan Horse virus?
A Trojan Horse is an email virus usually released by an email attachment. If opened, it will scour your hard drive for any personal and financial information such as your social security, account, and PIN numbers. Once it has collected your info, it is sent to a thief’s database.
The term comes from the a Greek story of the Trojan War, in which the Greeks give a giant wooden horse to their foes, the Trojans, ostensibly as a peace offering. But after the Trojans drag the horse inside their city walls, Greek soldiers sneak out of the horse's hollow belly and open the city gates, allowing their compatriots to pour in and capture Troy.
Types of Trojan horses
Trojan horses are almost always designed to do various harmful things, but could be harmless. They are broken down in classification based on how they breach systems and the damage they cause. The seven main types of Trojan horses are:
-Remote Access Trojans
-Data Sending Trojans
-Destructive Trojans
-Proxy Trojans
-FTP Trojans
-security software disabler Trojans
-denial-of-service attack (DoS) Trojans
.One thing you probably won't find a Trojan doing is scouring your hard drive for personal details, as the Visa description alleges.^ There is always a risk when allowing a computer you have not personally vetted access to your network.
