Latest Study Suggests Computers Remain Infected Far Longer Than Previously Suggested

Contrary to previous security reports suggesting compromised machines remain infected for 6 weeks, experts at Trend Micro say these estimates are far from accurate. In its recent blog post the company said: "During the analysis of approximately 100 million compromised IP addresses, we identified that half of all IP addresses were infected for at least 300 days. That percentage rises to eighty percent if the minimum time is reduced to a month." Additionally the study also indicates that while three quarter of the IP addresses were linked to consumer users, the remaining quarter belonged to enterprise users. more

Phishing Attack Attempts to Steal Consumer Data via Bogus Live-Chat Support

Security experts at RSA Research Lab have reported the discovery of a new type of phishing attack targeted against online banking customers that combines a typical phishing website with a live change session initiated by fraudsters. The technique dubbed "Chat-in-the-Middle" not only attempts to trick customers into entering their usernames and passwords into a phishing site but obtains further sensitive information (such as answers to secret questions used by banks to authenticate customers). According to the report, this attack is currently targeting a single U.S.-based financial institution, however operators of all online banking websites are cautioned. more

Major Organizations Overlooking High Priority Security Risks, Too Much Focus on OS

According to a new security report released today by SANS Institute, TippingPoint and Qualys, the number of vulnerabilities found in applications in the last few years is far greater than the number of vulnerabilities discovered in operating systems. "On average, major organizations take at least twice as long to patch client-side vulnerabilities as they take to patch operating system vulnerabilities. In other words the highest priority risk is getting less attention than the lower priority risk." more

Glaring Weaknesses in Prosecuting International Cyber Crime

I have to tell you -- I'm not really happy about the fact that the majority of serious cyber crime on the Internet happens without any legal prosecution. I spend an enormous amount of time -- far beyond my "day job" and exceeding what some might consider my professional capacity -- tracking cyber crime. I also work closely with law enforcement (both in the U.S. and abroad) to assist in the intelligence gathering process, putting the pieces of the puzzles together, connecting the dots, and so forth. And most of the major criminal organizations are still operating (pretty much) in the open, with fear of retribution or criminal prosecution, for a number of reasons. more

Latvian ISP Closure Dents Cutwail Botnet ...for a Whole 48 Hours

From MessageLabs' latest report: "Real Host, an ISP based in Riga, Latvia was alleged to be linked to command-and-control servers for infected botnet computers, as well as being linked to malicious websites, phishing websites and 'rogue' anti-virus products. Real Host was disconnected by its upstream providers on 1 August 2009. The impact was immediately felt, where spam volumes dropped briefly by as much as 38% in the subsequent 48-hour period. Much of this spam was linked to the Cutwail botnet, currently one of the largest botnets and responsible for approximately 15-20% of all spam. Its activity levels fell by as much as 90% when Real Host was taken offline, but quickly recovered in a matter of days." more

Apparently Legitimate Estonian ISP Operating as Large Cybercrime Hub Since 2005

An apparently legitimate ISP in Tartu, Estonian is reported to have been serving as the operational headquarters of a large cybercrime network since 2005 according to TrendWatch, the security research arm of TrendMicro. "An Estonian company is actively administering a huge number of servers in numerous datacenters, which together form a network to commit cybercrime. It appears that the company from Tartu, Estonia controls everything from trying to lure Internet users to installing DNS changer Trojans by promising them special video content, and finally to exploiting victims' machines for fraud with the help of ads and fake virus infection warnings..." more

Are Phishing and Malware Separate Threats?

Phishing is when bad guys try to impersonate a trusted organization, so they can steal your credentials. Typically they'll send you a fake e-mail that appears to be from a bank, with a link to a fake website that also looks like the bank. Malware offers another more insidious way to steal your credentials, by running unwanted code on your computer... I like VeriSign's characterization of this kind of malware as an insecure endpoint, the PC which is the endpoint of the conversation with the bank isn't actually under the control of the person who's using it. more

Twitter, DDoS and the Motivations Behind the Attack

As we all know by now, last week, on Thursday, August 7, Twitter was hit with a denial-of-service attack that took it down for several hours. Other social networking sites like Facebook, LiveJournal, Youtube and Blogger were also hit. They managed to repel the attack although Facebook was not quite as successful as the other larger players. The theory floating about at the moment is that this was a politically oriented play designed to target one guy: a blogger. We are nearing the 1-year anniversary of a the Russian/Georgian 2008 war. There is a pro-Georgian blogger by the username of "Cyxymu" who had accounts on all of these services. more

One Third of Companies Employing Staff to Monitor Content of Outbound Email, According to Survey

A recent survey of US companies conducted by Proofpoint has found companies increasingly concerned over data leaks via emplyee misuse of email, blogs, social networks, multimedia channels and text messages. From the report: "[A]s more US companies reported their business was impacted by the exposure of sensitive or embarrassing information (34 percent, up from 23 percent in 2008), an increasing number say they employ staff to read or otherwise analyze the contents of outbound email (38 percent, up from 29 percent in 2008). The pain of data leakage has become so acute in 2009 that more US companies report they employ staff whose primary or exclusive job is to monitor the content of outbound email (33 percent, up from 15 percent in 2008)." more

Afilias and Neustar to Collaborate With ISC on DNS Security Initiative

Internet Systems Consortium (ISC) has announced that it is working with Afilias and Neustar, Inc. in the effort to support ISC's DNSSEC Look-aside Validation (DLV) registry by providing secondary DNS service for the DLV zone. DLV is a mechanism that provides many of the benefits of DNSSEC (short for DNS Security Extensions), enabling domain holders to secure their domain information today in advance of broader DNSSEC deployment and adoption. "Adding Afilias and Neustar as secondary DNS providers for the DLV zone demonstrates our collective understanding that DLV is a vitally important production service bigger than any single provider in the same way that there are 13 root server operators, not just one." more

Dozens of US House of Representatives Websites Hacked

US House officials have confirmed hackers breaching several websites belonging to House of Representatives members in the past week. Portions of the websites were replaced by digital graffiti which began earlier this month, according to zone-h. Brian Krebs of the Washington Post reports: "Rep. Spencer Bachus has sent a letter to the House's chief administrative officer, requesting more information about the attacks. Bachus cites information provided to him by Gary Warner, director of research in computer forensics at the University of Alabama at Birmingham. Warner suggested that the break-ins at the House sites were caused not by password guessing [as reported initially], but by 'SQL injection,' an attack that exploits security weaknesses in Web server configurations." more

Twitter Taken Down by DDoS Attack, Company Confirms

The Twitter micro-blogging service was knocked offline this morning for several hours as a result of a denial of service attack (DDoS). Twitter has confirmed and reported the attack in a post on its official blog earlier today: "We are defending against this [DDos] attack now and will continue to update our status blog as we continue to defend and later investigate." The company later reported that the service as been resumed but they are still continuing to defend against and recover from this attack. No further updates have been provided yet. more

OpenDNSSEC Launched to Help Drive Adoption of DNSSEC

A team of developers including .SE (The Internet Infrastructure Foundation), LNetLabs, Nominet, Kirei, SURFnet, SIDN and John Dickinson have come together to create open source software, called OpenDNSSEC, to make it easier to deploy DNSSEC. Patrik Wallström, responsible for DNSSEC at .SE comments: "In order to spread the use of DNSSEC to an increased number of domain names, the management surrounding this technology must be simplified. Together with a number of collaborators, we're developing OpenDNSSEC. Leveraging our deployment experience, we will produce a well-packaged, easy-to-use and flexible DNSSEC tool that eliminates all manual procedures. Those in charge of name servers no longer need detailed knowledge about the protocol in order to use it." more

Survey Suggests Strained Budgets Causing Security Cutbacks on Known Threats

A recent survey of security professionals by RSA Conference with regards to critical security threats and infrastructure issues currently faced, revealed budgetary constrains as the top challenge currently faced. According to reports, the study suggests that even though practitioners are most concerned about email phishing and securing mobile devices, technologies addressing these needs are at risk of being cut from IT budgets. 72% percent of respondents indicated a rise in email-borne malware and phishing attempts since Fall 2008, with 57% stating they have seen an increase in Web-borne malware. Concerns about zero-day attacks and rogue employees as a result of layoffs were cited by 28% and 26% of survey respondents, respectively. more

Nuclear Command and Control Structures Vulnerable to Cyber Terrorism

A research paper commissioned by the International Commission on Nuclear Non-proliferation and Disarmament (ICNND) suggests that nuclear command and control systems are vulnerable to cyber terrorism. "Despite claims that nuclear launch orders can only come from the highest authorities, numerous examples point towards an ability to sidestep the chain of command and insert orders at lower levels," says the report. more
