Hacking Crisis Internet has grown very fast and security has lagged behind It can be hard to trace a perpetrator of cyber attacks because most are able to camouflage their identities Large scale failures on the internet can have a catastrophic impact on: the economy which relies heavily on electronic transactions human life, when hospitals or government agencies, such as first responders are targeted What is Hacking? The Process of attempting to gain or successfully gaining, unauthorized access to computer resources Who is a Hacker? In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. History of Hacking Began as early as 1903: Magician and inventor Nevil Maskelyne disrupts John Ambrose Fleming's public demonstration of Guglielmo Marconi's purportedly secure wireless telegraphy technology, sending insulting Morse code messages through the auditorium's projector The term “Hacker” originated in the 1960’s at MIT A network known as ARPANET was founded by the Department of Defense as a means to link government offices. In time, ARPANET evolved into what is today known as the Internet. -
Jeffrey Heim, Marcel Hernandez, Maria Nunez,& Matthias Katerna Morris Worm on November 2, 1988, Robert Tappan Morris Releas
Jeffrey Heim, Marcel Hernandez, Maria Nunez,& Matthias Katerna Morris Worm On November 2, 1988, Robert Tappan Morris released a worm into the internet. The experimental worm was the first of its kind. It replicated itself and programmed itself, so it ended up spreading much faster than Morris expected. It self-programmed and self-replicated at an exponential rate in a manner that had never been seen before. Morris knew this worm was not necessarily ethical, for he released it out of MIT instead of his own Cornell University. In due course, many computers across the United States had crashed because of Morris. Once he discovered how much damage the worm had been causing, he reached out to a friend at Harvard looking for a solution to stop it. They attempted in sending an anonymous message to the network with directions that could kill the worm, but the message came through too late since they system was clogged. Many significant computers at colleges, businesses and the military became infected. The cost to fix each computer ranged from $200 to over $53,000. The worm exploited vulnerabilities in computer systems and in the UNIX email software. Within 24 hours of releasing the worm, thousands of people were aware something was unusual. Eventually, it would infect ten percent of all computers using the internet. The Morris Worm was the largest malware case ever to reach this percentage. However, the percentage was so high due to the fact that the number of computers was much less than today. The computers it impacted included significant systems, such as Stanford’s, Berkley’s and NASA’s. -

Secure by Design, Secure by Default: Requirements and Guidance
Biometrics and Surveillance Camera Commissioner Secure by Design, Secure by Default Video Surveillance Products Introduction This guidance is for any organisation manufacturing Video Surveillance Systems (VSS), or manufacturing or assembling components intended to be utilised as part of a VSS. It is intended to layout the Biometrics and Surveillance Camera Commissioners (BSCC) minimum requirements to ensure such systems are designed and manufactured in a manner that assures they are Secure by Design. It also contains certain component requirements that will ensure a configuration that is Secure by Default when the component is shipped, thereby making it more likely that the system will be installed and left in a secure state. This guidance forms part of a wider suite of documentation being developed as part of the SCC Strategy, in support of the SCC Code of Practice. Background and Context The nature of the Internet means that connected devices can be subjected to a cyber attack from anywhere in the world. Widespread attacks on connected products is a current and real threat, and a number of highly publicised attacks have already occurred. The Mirai malware targeted devices such as internet-enabled cameras (IP cameras). Mirai was successful because it exploited the use of common default credentials (such as a username and password being set by the manufacturer as ‘admin’) and poor security configuration of devices. Ultimately, this facilitated attacks on a range of commercial and social media services and included an outage of streaming services such as Netflix. An evolution of Mirai, called Reaper, has also been discovered. Reaper used publicly and easily available exploits that remained unfixed (patched) and highlighted the problem around non patching of known security vulnerabilities, allowing attackers to utilise them to cause harm. -
Trojans and Malware on the Internet an Update
Attitude Adjustment: Trojans and Malware on the Internet An Update Sarah Gordon and David Chess IBM Thomas J. Watson Research Center Yorktown Heights, NY Abstract This paper continues our examination of Trojan horses on the Internet; their prevalence, technical structure and impact. It explores the type and scope of threats encountered on the Internet - throughout history until today. It examines user attitudes and considers ways in which those attitudes can actively affect your organization’s vulnerability to Trojanizations of various types. It discusses the status of hostile active content on the Internet, including threats from Java and ActiveX, and re-examines the impact of these types of threats to Internet users in the real world. Observations related to the role of the antivirus industry in solving the problem are considered. Throughout the paper, technical and policy based strategies for minimizing the risk of damage from various types of Trojan horses on the Internet are presented This paper represents an update and summary of our research from Where There's Smoke There's Mirrors: The Truth About Trojan Horses on the Internet, presented at the Eighth International Virus Bulletin Conference in Munich Germany, October 1998, and Attitude Adjustment: Trojans and Malware on the Internet, presented at the European Institute for Computer Antivirus Research in Aalborg, Denmark, March 1999.

8 Ways to Protect Your Network Against Ransomware
8 ways to protect your network against ransomware Steps to prevent ransomware attacks and save your money The ransomware threat Sometimes old becomes new again. Such is the case with ransomware attacks, which have become popular once more. First released in 1989, ransomware infects a system and “locks out” the user from accessing the device or files on it. Only when the victim agrees to pay a ransom, usually in the form of bitcoins, can the system be unlocked and accessed again. The following e-book provides eight ways you can protect your network against ransomware attacks and avoid giving your money to cybercriminals. Ransom amounts vary, but are often in the $200-$400 range.1 1. Educate your employees User education and awareness are critical when it comes to defeating ransomware. Treat suspicious emails with caution. Look at the domain name that sent the email. Check for spelling mistakes, review the signature and the legitimacy of the request. Hover over links to check where they lead to. 2. Use a multi-layered approach to network security Protection from ransomware and other forms of malware doesn’t begin and end at the gateway. Extending security through the use of anti-virus, anti-spyware, intrusion prevention and other technologies on devices at the network perimeter is critical. Adopt a layered approach to stop ransomware by avoiding a single point of failure in your security architecture. 2 3. Back up your files regularly Another safeguard against having to pay ransom is a robust backup and recovery strategy. Depending on how quickly the compromise is detected, how widely it has spread and the level of data loss that is acceptable, recovery from a backup could be a good option. -

Controlling Security Risk and Fraud in Payment Systems
Controlling Security Risk and Fraud in Payment Systems By Richard J. Sullivan n late 2013, a breach of the cashier system at a major retailer ex- posed information on 40 million debit and credit cards. That Ifraudsters can use the payment card numbers harvested in this breach to create fraudulent payments underscores one of many security weaknesses that can lead to payment fraud. The direct cost of fraud on automated clearinghouse (ACH), debit card, and credit card payments reached $6.1 billion in 2012. Investments and ongoing expenses for preventing, detecting, monitoring, and responding to payment fraud add considerably to direct costs. Fraud and security weaknesses in pay- ments can have an indirect cost as well if they cause concerned con- sumers and businesses to choose less efficient forms of payment. More broadly, the public’s loss of confidence in payments has had significant negative economic consequences in the past. A constant stream of news reports on data breaches, phishing attacks, spoofed websites, payment card skimmers, fraudulent ATM withdrawals, computer malware, and infiltrated retail point-of-sale systems should concern policymakers be- cause it indicates weak payment security and undermines confidence in payments. Richard J. Sullivan is a senior economist at the Federal Reserve Bank of Kansas City. Emily Cuddy and Joshua Hanson, research associates at the bank, helped prepare this article. This article is on the bank’s website at www.KansasCityFed.org. 47 48 FEDERAL RESERVE BANK OF KANSAS CITY Payment participants—end-users who make payments, financial institutions and nonbanks that provide payment services, and networks and service providers that process payments—all have considerable in- centive to secure payments and deter fraud. -
