CBS's 60 Minutes aired a special report last night investigating how hackers can get into the computer systems that run crucial elements of the world's infrastructure, such as the power grids, water works or even a nation's military arsenal. From the report: "At the Sandia National Laboratories, Department of Energy security specialists like John Mulder try to hack into computer systems of power and water companies, and other sensitive targets in order to figure out the best way to sabotage them. It's all done with the companies' permission in order to identify vulnerabilities. In one test, they simulated how they could have destroyed an oil refinery by sending out code that caused a crucial component to overheat." more
Anti-Phishing Working Group (APWG) released its latest Phishing Activity Trends Report today warning that the number of unique phishing websites detected in June rose to 49,084, the highest since April, 2007's record of 55,643, and the second-highest recorded since APWG began reporting this measurement. "The number of hijacked brands ascended to an all-time high of 310 in March and remained, in historical context, at an elevated level to the close of the half in June," says the report. more
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
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
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
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
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
Security researches report seeing as much unique malware in the first half of 2009 as seen in all of 2008. "This is quite something when you consider that in 2008 we saw the greatest ever growth in malware," says David Marcus of McAfee Avert Labs. More specifically, Marcus in a blog post writes that the numbers add up to an average of 200,000 unique pieces malware monthly or more than 6,000 a day. "Bear in mind these are malware we consider unique (something we had to write a driver for) and does not count all the other malware we detect generically or heuristically... When you add in the generic and heuristic detections the number becomes truly mind boggling," writes Marucs. more
According to reports by German software security company G Data, since the beginning of summer, the malware community appears to have been scaling back its activities. This considerable reduction is, according to the estimates of G Data security expert Ralf Benzmüller, not solely due to the forthcoming holiday season. The global recession appears to have also hit the eCrime economy. "This phenomenon emerges every year as something new. At the start of the holiday season, the number of malware programs falls. One reason for this is the worldwide onset of the travel season, which, based on experience, causes a drop in the number of active Internet users. However, this does not explain a collapse of more than 30 percent," says Ralf Benzmüller. more
The Anti-Phishing Working Group (APWG) recently reported that the number of sites infecting PCs with password-stealing crimeware reached an all time high of 31,173 in December 2008 - an 827 percent increase from January. And according to a report just released by Trend Micro's Focus Report, 93 percent of data-stealing malware have been identified as Trojans in the first quarter of 2009. more
While scanning its index, Google in the last two months reports to have found more than 4,000 different websites suspected of distributing malware by massively compromising popular websites. "Of these domains more than 1,400 were hosted in the .cn TLD. Several contained plays on the name of Google such as goooogleadsence.biz, etc.," says Google's security team member, Niels Provos, in a blog post today. more
In a speech today from the White House, President Obama declared that the United States' computers and digital networks are strategic national assets and that he will personally appoint a cybersecurity coordinator to oversee the effort to protect this critical infrastructure. more
As you may know, there are two laws currently being discussed in Canadian legislative assemblies: Senate Bill S-220, a private member’s bill with private right of action and criminal remedies; Parliamentary Bill C-27, tabled by the government, with private right of action, coordination between various enforcement agencies... more
A recent study suggests Rustock and Xarvester malware provided the most efficient spambot code, enabling individual zombie computers to send 600,000 spam messages each over a 24 hour period. "Over the past few years, botnets have revolutionized the spam industry and pushed spam volumes to epidemic proportions despite the best efforts of law enforcement and the computer security industry. Our intention was to better understand the origins of spam, and the malware that drives it," said Phil Hay, senior threat analyst, TRACElabs (a research arm of security company Marshal8e6)... more
Mike Hammer's thoughtful article, A Few Thoughts on the Future of Email Authentication, should trigger thoughtfulness in the rest of us. Email abuse has been around a long time. Anti-abuse efforts have too. Yet global abuse traffic has grown into the 90+% range, with no hint of trending downward. The best we hear about current effectiveness is for last-hop filtering, if you have the money, staff and skills to apply to the problem... more
