2016 Wrap-Up Cybercrime Tactics and Techniques
Cybercrime tactics and techniques 2016 wrap-up TABLE OF CONTENTS 01 Executive summary 02 Windows malware 05 Early 2017 Windows malware predictions 06 Mac malware 06 Early 2017 OS X malware predictions 07 Exploit kits 08 Early 2017 exploit kit predictions 09 Phishing and malspam 10 Early 2017 phishing and malspam predictions 11 Potentially Unwanted Programs 11 Early 2017 PUP predictions 12 Tech support scams 13 Early 2017 tech support scam predictions 14 Conclusion Introduction Last year was interesting for malware distribution and development. While we still experienced a flood of ransomware and immense distribution of malware using malspam/phishing/exploit kits, some major players, such as TeslaCrypt and Angler EK, vanished, while some new names dominated. In our first wrap-up of the threat landscape, we are going to cover the trends observed during the last few months of 2016, take an analyst’s view of the threats, and offer some predictions for the beginning of 2017. Moving forward, every quarter we will bring you a view of the threat landscape through the eyes of Malwarebytes researchers and analysts. Executive summary Ransomware dominated in 2016 and continued to do so However, it’s market share and capabilities are not quite into 2017. We expect to see very little variation in this at par with Angler, though this is likely going to change in early 2017, and if anything, it is getting worse. The as we expect to observe an increase in exploit kit most notable ransomware families of the end of 2016 activity by the middle of 2017. While late 2016 showed were Locky and Cerber, two very similar ransomware a decrease in the amount of malicious spam/phishing families that took the number one slot multiple times attacks targeting users in the wild, we are seeing greater during the last part of the year. -

Trust, trust dependency, high skill base criminals and opportunity zones were, and are, the hallmarks of white collar crime. The emerging paradigm of virtual collar crimes negates the requirement that perpetrators be highly skilled. Computer sagacity is no longer the sine qua non for cybercriminals - the phenomenon of 'Crime as a Service' has outsourced the skill requirement to third party providers of the required technological knowhow. Alongside the cascading down of such technical knowledge, twenty-first century society has driven headlong down the information superhighway, with hardly any area of human activity left unexposed to the effects of the ether. -
Using Dmarc to Improve Your Email Reputation Zink
USING DMARC TO IMPROVE YOUR EMAIL REPUTATION ZINK USING DMARC TO IMPROVE up with ways to mitigate this problem using two primary technologies. YOUR EMAIL REPUTATION Terry Zink 1.1 Terminology Microsoft, USA In email, people naturally thing that the sender of the message is the one in the From: fi eld – the one that they see in their email Email [email protected] client. For example, suppose that you are a travel enthusiast and you receive the email shown in Figure 3. You received the message ‘from’ [email protected], right? Wrong. ABSTRACT In email, there are two ‘From’ addresses: In 2012, the world of email fi ltering created a new tool to combat 1. The SMTP MAIL FROM, otherwise known as the RFC spam and phishing: DMARC [1, 2]. DMARC, or Domain-based 5321.MailFrom [3].

In order to do so, the report analyses from a technical point of view the core set of communication protocols and standards that support email communications in order to identify and understand the existing security and privacy vulnerabilities. On the basis of this analysis, the report identifies and analyses technical countermeasures, in the form of newer standards, protocols and tools, aimed at ensuring a better protection of the security and privacy of email communications. -
Cyber Frauds, Scams and Their Victims
4 ‘NOT A VICTIMLESS CRIME’ The impact of fraud upon victims Distribution Introduction1 for It is surprising to note that despite extensive research on crime victimisation there has only been a very small amount of research on fraud victims (Croall, 2001; Fraud Advisory Panel, 2006; Ganzini et al., 1990; Levi, 2001; Levi, 1999; Not Levi and Pithouse, 1992; Spalek, 1999). This literature highlights some of the devastating consequences and impacts of fraud on the victim. For some, such is the severity of the harm they experience, it has been likened to that of violent crime (Marsh, 2004). Further to this, there is evidence from some victims who express feelings in the aftermath of online fraud that they have been ‘mentally raped’ (Whitty and Buchanan, 2016: 180; see also Deem, 2000: 37). While the Francis: most obvious consequence is financial harm, it is important to recognise that the impacts of fraud go far beyond that of pure monetary losses. However, the & financial loss can be significant. For some victims, such is the loss that they are re- quired to sell assets (often their home), go back to work (if they were retired), or are unable to secure credit or sometimes in the worst case scenario they may even become bankrupt. This chapter will explore the impact of fraud on the victims, examining both the financial and non-financial harms experienced by these vic- Taylor tims, and in doing so it will draw upon some of the latest research from around the world. The chapter will start with an examination of the impact of crime in general, before exploring some of the specific impacts of fraud, which have been noted in the research. -

Cybercrime: an Overview of the Federal Computer Fraud and Abuse Statute and Related Federal Criminal Laws
Cybercrime: An Overview of the Federal Computer Fraud and Abuse Statute and Related Federal Criminal Laws Charles Doyle Senior Specialist in American Public Law October 15, 2014 Congressional Research Service 7-5700 www.crs.gov 97-1025 Cybercrime: An Overview of 18 U.S.C. 1030 and Related Federal Criminal Laws Summary The Computer Fraud and Abuse Act (CFAA), 18 U.S.C. 1030, outlaws conduct that victimizes computer systems. It is a cyber security law. It protects federal computers, bank computers, and computers connected to the Internet. It shields them from trespassing, threats, damage, espionage, and from being corruptly used as instruments of fraud. It is not a comprehensive provision, but instead it fills cracks and gaps in the protection afforded by other federal criminal laws. This is a brief sketch of CFAA and some of its federal statutory companions, including the amendments found in the Identity Theft Enforcement and Restitution Act, P.L. 110-326, 122 Stat. 3560 (2008). In their present form, the seven paragraphs of subsection 1030(a) outlaw • computer trespassing (e.g., hacking) in a government computer, 18 U.S.C. 1030(a)(3); • computer trespassing (e.g., hacking) resulting in exposure to certain governmental, credit, financial, or computer-housed information, 18 U.S.C. 1030(a)(2); • damaging a government computer, a bank computer, or a computer used in, or affecting, interstate or foreign commerce (e.g., a worm, computer virus, Trojan horse, time bomb, a denial of service attack, and other forms of cyber attack, cyber crime, or cyber terrorism), 18 U.S.C.
