Comments Off on Malware Infections On Android Rising
An increasing number of Android phones are infected with mobile malware programs that are capable of turning the handsets into spying devices, according to a report from Kindsight Security Labs, a subsidiary of telecommunications equipment vendor Alcatel-Lucent.
The vast majority of mobile devices infected with malware are running the Android operating system and a third of the top 20 malware threats for Android by infection rate fall into the spyware category, Kindsight said in a report released Tuesday that covers the second quarter of 2013.
The Alcatel-Lucent subsidiary sells security appliances to ISPs (Internet service providers) and mobile network operators that can identify known malware threats and infected devices by analyzing the network traffic.
Data collected from its product deployments allows the company to compile statistics about how many devices connected to mobile or broadband networks are infected with malware and determine what are the most commonly detected threats.
The malware infection rate for devices connected to mobile networks is fairly low, averaging at 0.52%, Kindsight said in its report. These infected devices include mobile phones as well as Windows laptops that use a mobile connection through a phone, a 3G USB modem or a mobile hotspot device.
In January the number of infected mobile phones accounted for slightly more than 30% of all infected devices connected to mobile networks, but by June they grew to more than 50%.
The vast majority of infected mobile phones run Android. Those running BlackBerry, iOS and other operating systems represent less than 1% of infected mobile devices, Kindsight said.
When calculated separately, on average more than 1% of Android devices on mobile networks are infected with malware, Kindsight said in its report.
The malware threat most commonly seen on Android devices was an adware Trojan program called Uapush.A that sends SMS messages and steals information, Kindsight said. Uapush.A was responsible for around 53% of the total number of infections detected on Android devices.
Phishing Attacks Increasing
Security researchers at Kaspersky Lab have reported significant growth in phishing attacks over the last year.
In a study entitled “The Evolution of Phishing Attacks”, Kaspersky said it found 37.3 million out of its 50 million customers running its security products that were at risk of being phished from 2012 to the present, an 87 percent increase over the same period between 2011 and 2012.
“The nature of phishing attacks is such that the simplest types can be launched without any major infrastructure investments or in-depth technological research,” Kaspersky said in the report.
“This situation has led to its own form of ‘commercialization’ of these types of attacks, and phishing is now being almost industrialized, both by cybercriminals with professional technological skills and IT dilettantes.”
The security firm explained that overall, the effectiveness of phishing, combined with its profitability for criminals and how simple the process is to undertake has led to a steadily rising number of these types of incidents.
Kaspersky noted that most of the victims in 2012-2013 were located in just ten countries, that is, Russia, the US, India, Germany, Vietnam, the UK, France, Italy, China and Ukraine. These 10 countries were home to 64 percent of all phishing attack victims during this time.
In addition to a rise in the number of users attacked, the number of servers involved in phishing attacks also increased, Kaspersky said, without giving any exact numbers. Though the firm did reveal that internet giants like Yahoo, Google, Facebook and Amazon are the top targets of malicious users.
“Online game services, online payment systems, and the websites of banks and other credit and financial organizations are also common targets,” the firm added, warning users to stay vigilant when entering personal data.
McAffee See Sure In Spam
The first three months of 2013 have seen a surge in spam volume, as well as a growing number of samples of the Koobface social networking worm and master boot record (MBR) infecting malware, according to antivirus vendor McAfee.
After remaining relatively stable throughout 2012, spam levels rose during the first quarter of 2013, reaching the highest volume seen in the past two years, McAfee said in a report released Monday.
The amount of spam originating from some countries rose dramatically, McAfee said. Spam from Belarus increased by 540% while spam originating in Kazakhstan grew 150%.
Cutwail, also known as Pushdo, was the most prevalent spam-sending botnet during the first quarter, McAfee said.
The increased Pushdo activity has recently been observed by other security companies as well. Last month, researchers from security firm Damballa found a new variant of the Pushdo malware that’s more resilient to coordinated takedown efforts.
On the malware front, McAfee has also seen a surge in the number of Koobface samples, which reached previously unseen levels during the first quarter of 2013. First discovered in 2008, Koobface is a worm that spreads via social networking sites, especially through Facebook, by hijacking user accounts.
The number of malware samples designed to infect a computer’s master boot record (MBR) also reached a record high during the first three months of 2013, after increasing during the last quarter of 2012 as well, McAfee said.
The MBR is a special section on a hard disk drive that contains information about its partitions and is used during the system startup operation. “Compromising the MBR offers an attacker a wide variety of control, persistence, and deep penetration,” the McAfee researchers said in the report.
The MBR attacks seen during the first quarter involved malware like StealthMBR, also known as Mebroot; Tidserv, also known as Alureon, TDSS and TDL; Cidox and Shamoon, they said.
Twitter’s Authentication Has Vulnerabilities

Comments Off on Twitter’s Authentication Has Vulnerabilities
Twitter’s SMS-based, two-factor authentication feature could be abused to lock users who have not enabled it for their accounts if attackers gain access to their log-in credentials, according to researchers from Finnish antivirus vendor F-Secure.
Twitter introduced two-factor authentication last week as an optional security feature in order to make it harder for attackers to hijack users’ accounts even if they manage to steal their usernames and passwords. If enabled, the feature introduces a second authentication factor in the form of secret codes sent via SMS.
According to Sean Sullivan, a security advisor at F-Secure, attackers could actually abuse this feature in order to prolong their unauthorized access to those accounts that don’t have two-factor authentication enabled. The researcher first described the issue Friday in a blog post.
An attacker who steals someone’s log-in credentials, via phishing or some other method, could associate a prepaid phone number with that person’s account and then turn on two-factor authentication, Sullivan said Monday. If that happens, the real owner won’t be able to recover the account by simply performing a password reset, and will have to contact Twitter support, he said.
This is possible because Twitter doesn’t use any additional method to verify that whoever has access to an account via Twitter’s website is also authorized to enable two-factor authentication.
When the two-factor authentication option called “Account Security” is first enabled on the account settings page, the site asks users if they successfully received a test message sent to their phone. Users can simply click “yes,” even if they didn’t receive the message, Sullivan said.
Instead, Twitter should send a confirmation link to the email address associated with the account for the account owner to click in order to confirm that two-factor authentication should be enabled, Sullivan said.
As it is, the researcher is concerned that this feature could be abused by determined attackers like the Syrian Electronic Army, a hacker group that recently hijacked the Twitter accounts of several news organizations, in order to prolong their unauthorized access to compromised accounts.
Some security researchers already expressed their belief that Twitter’s two-factor authentication feature in its current implementation is impractical for news organizations and companies with geographically dispersed social media teams, where different employees have access to the same Twitter account and cannot share a single phone number for authentication.
Twitter did not immediately respond to a request for comment regarding the issue described by Sullivan.
Anonymous Goes After North Korea
Anonymous has restarted its attack against North Korea and once again is using a North Korean Twitter account to announce website scalps.
The Twitter account @uriminzok was the scene of announcements about the hacked websites during the last stage of Op North Korea, and reports have tipped up there again.
The first wave of attacks saw a stream of websites defaced or altered with messages or images that were very much not in favour of the latest North Korean hereditary leader, Kim Jong-un.
They were supported by a Pastebin message signed by Anonymous that called for some calming of relations between North Korea and the US, and warned of cyber attacks in retaliation.
“Citizens of North Korea, South Korea, USA, and the world. Don’t allow your governments to separate you. We are all one. We are the people. Our enemies are the dictators and regimes, our goals are freedom and peace and democracy,” read the statement. “United as one, divided by zero, we can never be defeated!”
Before the attacks restarted, the last Twitter message promised that more was to come. It said, “OpNorthKorea is still to come. Another round of attack on N.Korea will begin soon.” Anonymous began delivering on that threat in the early hours this morning.
More of North Korean websites are in our hand. They will be brought down.

We’ve counted nine websites downed, defacements and hacks, and judging by the stream of confirmations they happened over a two hour period. No new statement has been released other than the above.

Downed websites include the glorious uriminzokkiri.com, a North Korean news destination. However, when we tried it we had intermittent access.
Last time around the Anonymous hackers had taken control of North Korea’s Flickr account. This week we found the message, “This member is no longer active on Flickr.”
Passwords Continue As The Weakest Link
Comments Off on Passwords Continue As The Weakest Link
Passwords aren’t the only failure point in many recent widely publicized intrusions by hackers.
But passwords played a part in the perfect storm of users, service providers and technology failures that can result in epic network disasters. Password-based security mechanisms — which can be cracked, reset and socially engineered — no longer suffice in the era of cloud computing.
The problem is this: The more complex a password is, the harder it is to guess and the more secure it is. But the more complex a password is, the more likely it is to be written down or otherwise stored in an easily accessible location, and therefore the less secure it is. And the killer corollary: If a password is stolen, its relative simplicity or complexity becomes irrelevant.
Password security is the common cold of our technological age, a persistent problem that we can’t seem to solve. The technologies that promised to reduce our dependence on passwords — biometrics, smart cards, key fobs, tokens — have all thus far fallen short in terms of cost, reliability or other attributes. And yet, as ongoing news reports about password breaches show, password management is now more important than ever.
All of which makes password management a nightmare for IT shops. “IT faces competing interests,” says Forrester analyst Eve Maler. “They want to be compliant and secure, but they also want to be fast and expedient when it comes to synchronizing user accounts.”
Windows 7 Infection Rate Soaring
Windows 7′s malware infection rate soared by as much as 182% this year, Microsoft said on Tuesday.
But even with that dramatic increase, Windows 7 remained two to three times less likely to fall to hacker attack than the aged Windows XP.
Data from Microsoft’s newest twice-yearly security report showed that in the second quarter of 2012, Windows 7 was between 33% and 182% more likely to be infected by malware than in the second quarter of 2011.
The infection rate for Windows RTM, or “release to manufacturing,” the original version launched in Oct. 2009, was 33% higher this year for the 32-bit edition (x86), 59% higher for the 64-bit (x64) OS.
Windows 7 Service Pack 1 (SP1) — the upgrade that shipped in Feb. 2011 — saw even larger infection increases: 172% for x86, 182% for x64.
Microsoft blamed several factors for the boost in successful malware attacks, including less savvy users.
“This may be caused in part by increasing acceptance and usage of the newest consumer version of Windows,” said Microsoft in its latest Security Intelligence Report. “Early adopters are often technology enthusiasts who have a higher level of technical expertise than the mainstream computing population. As the Windows 7 install base has grown, new users are likely to possess a lower degree of security awareness than the early adopters and be less aware of safe online practices.”
Kaspersky Finds New Malware
Kaspersky Lab has discovered three Flame spyware related malware threats that it said use “sophisticated encryption methods”.
Kaspersky claims that it uncovered the three new hostile programs while analysing a number of Command and Control (C&C) servers used by Flame’s creators.
“Sophisticated encryption methods were utilised so that no one, but the attackers, could obtain the data uploaded from infected machines,” the firm’s statement read.
“The analysis of the scripts used to handle data transmissions to the victims revealed four communication protocols, and only one of them was compatible with Flame.
“It means that at least three other types of malware used these Command and Control servers. There is enough evidence to prove that at least one Flame-related malware is operating in the wild.”
The discovery of the three programs indicates that Flame’s Command and Control platform was being developed in 2006, four years earlier than first thought.
Flame was originally uncovered in May targeting Iranian computer systems. The malware drew widespread concerns within the security industry regarding its advanced espionage capabilities.
The full scale of Flame and its overarching implications remain unknown, despite the ongoing joint research campaign being mounted by Kaspersky, IMPACT, CERT-Bund/BSI and Symantec.
“It was problematic for us to estimate the amount of data stolen by Flame, even after the analysis of its Command and Control servers,” said Kaspersky’s chief security expert, Alexander Gostev.
Following the discovery of the three new related programs, Kaspersky’s chief malware expert Vitaly Kamluk told The INQUIRER that Flame is not the only one in this big family.
“There are others and they aren’t just other known malwares such as Stuxnet, Gauss or Duqu,” he said. “They stay in the shadows and no one has published anything about them yet. Others were probably used for different campaigns.”
Kamluk added that it is “very possible” there are more than the three listed in Kaspersky’s report.
“They started building RedProtocol, yet another ‘language’ for unknown malware. No known client types are using that one, which means that there is even more malware out there,” he added.
Microsoft Gives Money To Hackers
Microsoft has given out more than $250,000 in prize money to Black Hat hackers who found ways to protect its software. Redmond’s first Blue Hat prize were unveiled at a hip club at a mobbed party complete with dancers, high-energy DJ, and explosions of shimmering confetti.
The top prize of $200,000 went to doctoral student Vasilis Pappas. Pappas came up with a method to countering “the most popular attack technique” that Redmond is seeing at the moment. This is called Return-Oriented Programming which is a hacker technique that is often used to disable or circumvent a program’s computer security controls. Pappas came up with something called kBouncer which blocks anything that looks like an ROP attack from running.
Microsoft security response center senior director Mike Reavey said that Redmond posed a challenge to the researcher community and asked them to shift their focus from solely identifying and reporting individual vulnerabilities to investing in new lines of defensive research that could mitigate entire classes of attacks.
Windows Malware Hides In iOS App
Windows malware slipped past Apple’s eye and has been found tucked into software available on the company’s iOS App Store.
Although the malware, labeled a worm by Microsoft and tagged as “Win32/VB.CB” by the company, is harmless against Apple’s iOS and OS X operating systems, it may pose a threat to iTunes customers who download iPhone and iPad apps to their Windows PCs before syncing to their mobile devices.
A user reported Win32/VB.CB to Apple’s support forum around 10:30 a.m. ET Tuesday. The user, identified only as ”deesto,” said that his or her OS X antivirus warned that “Instaquotes-Quotes Cards for Instagram” was infected.
