  • Fortinet's March Threatscape Report Shows Domination of Ransomware and Troublesome Zero-Day
    Fortinet's March Threatscape Report Shows Domination of Ransomware and Troublesome Zero-Day Rise of Ransomware Is Primarily Driven by Bredolab and Pushdo Botnets SUNNYVALE, CA, Apr 01, 2010 (MARKETWIRE via COMTEX News Network) -- Fortinet(R) (NASDAQ: FTNT) -- a leading network security provider and worldwide leader of unified threat management (UTM) solutions -- today announced its March 2010 Threatscape report showed domination of ransomware threats with nine of the detections in the malware top ten list resulting in either scareware or ransomware infesting the victim's PC. Fortinet observed the primary drivers behind these threats to be two of the most notorious botnet "loaders" -- Bredolab and Pushdo. Another important finding is the aggressive entrance of a new zero-day threat in FortiGuard's top ten attack list, MS.IE.Userdata.Behavior.Code.Execution, which accounted for 25 percent of the detected activity last month. Key threat activities for the month of March include: -- SMS-based Ransomware High Activity: A new ransomware threat -- W32/DigiPog.EP -- appeared in Fortinet's top ten malware list. DigiPog is an SMS blocker using Russian language, locking out a system and aggressively killing off popular applications like Internet Explorer and Firefox until an appropriate code is entered into a field provided to the user. To obtain the code, a user must send an SMS message to the provided number, receiving a code in return. Upon execution, DigiPog registers the user's MAC address with its server. It is the first time that SMS-based ransomware enters Fortinet's top ten list, showing that the rise of ransomware is well on its way.

  • PC Anti-Virus Protection 2011
    PC Anti-Virus Protection 2011 12 POPULAR ANTI-VIRUS PROGRAMS COMPARED FOR EFFECTIVENESS Dennis Technology Labs, 03/08/2010 www.DennisTechnologyLabs.com This test aims to compare the effectiveness of the most recent releases of popular anti-virus software1. The products include those from Kaspersky, McAfee, Microsoft, Norton (Symantec) and Trend Micro, as well as free versions from Avast, AVG and Avira. Other products include those from BitDefender, ESET, G-Data and K7. The tests were conducted between 07/07/2010 and 22/07/2010 using the most up to date versions of the software available. A total of 12 products were exposed to genuine internet threats that real customers could have encountered during the test period. Crucially, this exposure was carried out in a realistic way, reflecting a customer’s experience as closely as possible. For example, each test system visited real, infected websites that significant numbers of internet users were encountering at the time of the test. These results reflect what would have happened if those users were using one of the seven products tested. EXECUTIVE SUMMARY Q Products that block attacks early tended to protect the system more fully The nature of web-based attacks means that the longer malware has access to a system, the more chances it has of downloading and installing further threats. Products that blocked the malicious and infected websites from the start reduced the risk of compromise by secondary and further downloads. Q 100 per cent protection is rare This test recorded an average protection rate of 87.5 per cent. New threats appear online frequently and it is inevitable that there will be times when specific security products are unable to protect from some of these threats.

REPORT HIGHLIGHTS Spam – 89.4% in February (an increase of 5.5% since January) Viruses – One in 302.8 emails in February contained malware (an increase of 0.02% since January) Phishing – One in 456.3 emails comprised a phishing attack (an increase of 0.04% since January) Malicious websites – 4,998 websites blocked per day (an increase of 184% since January) 41.6% of all malicious domains blocked were new in February (a decrease of 0.1% since January) 13.3 of all web-based malware blocked was new in February (an increase of 1.2% since January) Grum and Rustock to Blame for February Spam Surge While Volume Grows, Spam File Size Shrinks Waledac Botnet Makes a Comeback before its Demise Olympics-Themed Targeted Malware Gumblar Update REPORT ANALYSIS Grum and Rustock to Blame for Surge in February Spam As expected this time of year, spammers launched a number of spam campaigns related to St. Valentine‟s Day, celebrated on February 14. Around this time, spammers often change their spam runs to include references to the special date. However, the 5.5% increase in spam this month cannot be completely blamed on St. Valentine‟s Day alone. Figure 1 highlights the most recent spam surges in February, and further analysis reveals the underlying cause of these increases.

    JR04-2010 KOOBFACE: Inside a Crimeware Network By NART VILLENEUVE with a foreword by Ron Deibert and Rafal Rohozinski November 12, 2010 WEB VERSION. Also found here: INFOWAR http://www.infowar-monitor.net/koobface MONITOR JR04-2010 Koobface: Inside a Crimeware Network - FOREWORD I Foreword There is an episode of Star Trek in which Captain Kirk and Spock are confronted by their evil doppelgängers who are identical in every way except for their more nefarious, diabolical character. The social networking community Facebook has just such an evil doppelgänger, and it is called Koobface. Ever since the Internet emerged from the world of academia and into the world-of-the-rest-of-us, its growth trajectory has been shadowed by the emergence of a grey economy that has thrived on the opportunities for enrichment that an open, globally connected infrastructure has made possible. In the early years, cybercrime was clumsy, consisting mostly of extortion rackets that leveraged blunt computer network attacks against online casinos or pornography sites to extract funds from frustrated owners. Over time, it has become more sophisticated, more precise: like muggings morphing into rare art theft. The tools of the trade have been increasingly refined, levering ingenuous and constantly evolving malicious software (or malware) with tens of thousands of silently infected computers to hide tracks and steal credentials, like credit card data and passwords, from millions of unsuspecting individuals. It has become one of the world economy’s largest growth sectors—Russian, Chinese, and Israeli gangs are now joined by upstarts from Brazil, Thailand, and Nigeria—all of whom recognize that in the globally connected world, cyberspace offers stealthy and instant means for enrichment.

  • Targeted Attacks and Operation Aurora
    1. Infrastructure Security Targeted Attacks and Operation Aurora In this report, we will explain incidents that occurred between January and March 2010, and also examine incidents similar to Gumblar that have been occurring since December last year, as well as targeted attacks on U.S. corporations. Additionally, we will take a look at IIJ's MITF anti-malware activities and the technology involved. 1.1 Introduction This report summarizes incidents to which IIJ responded, based on general information obtained by IIJ itself related to the stable operation of the Internet, information from observations of incidents, information acquired through our services, and information obtained from companies and organizations with which IIJ has cooperative relationships. This volume covers the period of time from January 1 through March 31, 2010. In this period incidents of Gumblar and similar malware designed to steal IDs and passwords that we examined in our last report continued to occur, and many website alterations related to these incidents have been reported. A series of vulnerabilities that affect Web browsers and servers were also discovered. Besides these there was also a hijacking incident in which DNS information was manipulated without authorization, and SEO poisoning incidents that took advantage of a natural disaster. Targeted attacks on a number of major U.S. corporations were also a major topic. As seen above, the Internet continues to experience many security-related incidents. 1.2 Incident Summary Here, we discuss the IIJ handling and response to incidents that occurred between January 1 and March 31, 2010. Figure 1 shows the distribution of incidents handled during this period*1.

  • Understanding Adversarial Strategies from Bot Recruitment to Scheduling
    Understanding Adversarial Strategies from Bot Recruitment to Scheduling 1 2(B) 1 1 Wentao Chang , Aziz Mohaisen ,AnWang, and Songqing Chen 1 George Mason University, Fairfax, USA {wchang7,awang10,sqchen}@gmu.edu 2 The University of Central Florida, Orlando, USA [email protected] Abstract. Today botnets are still one of the most prevalent and devas- tating attacking platforms that cyber criminals rely on to launch large scale Internet attacks. Botmasters behind the scenes are becoming more agile and discreet, and some new and sophisticated strategies are adopted to recruit bots and schedule their activities to evade detection more effectively. In this paper, we conduct a measurement study of 23 active botnet families to uncover some new botmaster strategies based on an operational dataset collected over a period of seven months. Our analysis shows that different from the common perception that bots are randomly recruited in a best-effort manner, bots recruitment has strong geograph- ical and organizational locality, offering defenses a direction and priority when attempting to shut down these botnets. Furthermore, our study to measure dynamics of botnet activity reveals that botmasters start to deliberately schedule their bots to hibernate and alternate in attacks so that the detection window becomes smaller and smaller. Keywords: Distributed denial of service · Botnets Behavioral analysis 1 Introduction Botnets are collections of networks of infected machines (aka bots) that are widely used to carry out a variety of malicious activities as instructed by a botmaster. As a result, botnets are notoriously known as one of the primary attack and threat vectors utilized against critical infrastructures and services in activities that include distributed denial of service (DDoS), spam distribution, phishing, scanning and network exploration, among others.
