Comments Off on Will The FBI Ditch Blackberry?
Samsung Electronics Co Ltd is close to signing a deal to sell its popular line of Galaxy devices to the U.S. Federal Bureau of Investigation, sources familiar with the situation said late last Friday.
The deal would be a boost for Samsung, which is increasingly seeking to cater to the needs of government agencies, a niche long dominated by Canadian smartphone maker BlackBerry Ltd.
The FBI, with more than 35,000 employees, at present uses mainly BlackBerry devices. It is unclear whether the agency plans to replace all BlackBerry equipment with Galaxy models or whether it will use hardware from both companies.
A spokeswoman for the FBI declined to comment on the matter, saying that the selection of its new smartphones is part of an active acquisition process and any current discussions are proprietary to the government.
The imminent deal was initially reported by the Wall Street Journal late on Thursday. The WSJ also said Samsung is close to signing a smaller order for its devices with the U.S. Navy, citing people familiar with the matter.
Representatives of BlackBerry and Samsung declined to comment. BlackBerry emphasized, however, that it regards its operating system as the best in the market in terms of security features.
“The security of mobile devices is more important now than it has ever been before,” BlackBerry’s chief legal officer, Steve Zipperstein, said in an interview. “It is fair to ask why in this context anyone would consider moving from the gold standard in security, which is the BlackBerry platform.”
In May, the U.S. Pentagon cleared Samsung’s Android mobile devices and a new line of BlackBerry devices powered by the BB10 operating system for use on Defense Department networks.
Samsung has been pushing hard to convince government agencies and corporate clients that its Galaxy devices, powered by Google Inc’s Android operating system, can meet their stringent security needs.
The South Korean company hopes that the Pentagon clearance and the imminent deal with the FBI will help boost sales to security-conscious clients including banks and law firms.
Some analysts remain skeptical about whether Android can meet all security requirements of such clients, and note that the FBI itself has highlighted some vulnerabilities of the platform.
“The Android operating system hasn’t been secured properly,” said Rob Enderle, principal analyst with Enderle Group, noting that Samsung has layered technology on top of the operating system in an attempt to make its Galaxy devices safer.
DDoS Attacks Rising
One in five UK businesses experienced a DDoS attack last year according to a new survey.
Analytics firm Neustar said that while the percentage is significantly lower than that experienced by their US equivalents it is still fairly high. More than 22 percent of the 381 organisations participating in the annual trends study reported DDoS attacks, compared to 35 percent experiencing the same in a separate study carried out among US firms in 2012.
Neustar set out to measure revenue ‘risk per hour’ which is a measure of what it might cost a business in a particular sector to experience DdoS downtime. They found that the majority of organisations reckoned this at less than $1,500 per hour.
Most of the rest put it somewhere between $1,500 and $15,000 although one in four financial services firms put the number at $250,000 per hour. This cost included brand damage and unexpected customer service calls.
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.
Are CCTV Cameras Hackable?

Comments Off on Are CCTV Cameras Hackable?
When the nosy British bought CCTV cameras, worried citizens were told that they could not be hacked.
Now a US security expert says he has identified ways to remotely attack high-end surveillance cameras used by industrial plants, prisons, banks and the military. Craig Heffner, said he discovered the previously unreported bugs in digital video surveillance equipment from firms including Cisco, D-Link and TRENDnet.
They could use it as a pivot point, an initial foothold, to get into the network and start attacking internal systems. Heffner said that it was a significant threat as somebody could potentially access a camera and view it. Or they could also use it as a pivot point, an initial foothold, to get into the network and start attacking internal systems.
He will show how to exploit these bugs at the Black Hat hacking conference, which starts on July 31 in Las Vegas. Heffner said he has discovered hundreds of thousands of surveillance cameras that can be accessed via the public internet.
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.
Google Updates It’s SSL Certificate
Google has announced plans to upgrade its Secure Sockets Layer (SSL) certificates to 2048-bit keys by the end of 2013 to strengthen its SSL implementation.
Announcing the news on a blog post today, Google’s director of information security engineering Stephen McHenry said it will begin switching to the new 2048-bit certificates on 1 August to ensure adequate time for a careful rollout before the end of the year.
“We’re also going to change the root certificate that signs all of our SSL certificates because it has a 1024-bit key,” McHenry said.
“Most client software won’t have any problems with either of these changes, but we know that some configurations will require some extra steps to avoid complications. This is more often true of client software embedded in devices such as certain types of phones, printers, set-top boxes, gaming consoles, and cameras.”
McHenry advised that for a smooth upgrade, client software that makes SSL connections to Google, for example, HTTPS must: “perform normal validation of the certificate chain; include a properly extensive set of root certificates contained […]; and support Subject Alternative Names (SANs)”.
He also recommended that clients support the Server Name Indication (SNI) extension because they might need to make an extra API call to set the hostname on an SSL connection.
He pointed out some of the problems that the change might trigger, and pointed to a FAQ addressing certificate changes, as well as instructions for developers on how to adapt to certificate changes.
F-secure’s security researcher Sean Sullivan advised, “By updating its SSL standards, Google will make it easier to spot forged certificates.
“Certificate authorities have been abused and/or hacked in the past. I imagine it will be more difficult to forge one of these upgraded certs. Therefore, users can have more confidence.”
Adobe Reader Security Issue Found
McAfee has discovered a vulnerability in Adobe’s Reader program that allows people to track the usage of a PDF file.
“Recently, we detected some unusual PDF samples,” McAfee’s Haifei Li said in a blog post. “After some investigation, we successfully identified that the samples are exploiting an unpatched security issue in every version of Adobe Reader.”
The affected versions of Adobe Reader also include the latest “sandboxed” Reader XI (11.0.2).
McAfee said that the issue is not a “serious problem” because it doesn’t enable code execution, however it does permit the sender to see when and where a PDF file has been opened.
This vulnerability could only be dangerous if hackers exploited it to collect sensitive information such as IP address, internet service provider (ISP), or even the victim’s computing routine to eventually launch an advanced persistent threat (APT).
McAfee said that it is unsure who is exploiting this issue or why, but have found the PDFs to be delivered by an “email tracking service” provider.
The vulnerability works when a specific PDF JavaScript API is called with the first parameter having a UNC-located resource.
“Adobe Reader will access that UNC resource. However, this action is normally blocked and creates a warning dialog,” Li said. “The danger is that if the second parameter is provided with a special value, it changes the API’s behavior. In this situation, if the UNC resource exists, we see the warning dialog.
“However, if the UNC resource does not exist, the warning dialog will not appear even though the TCP traffic has already gone.”
McAfee said that it has reported the issue to Adobe and is waiting for their confirmation and a future patch. Adobe wasn’t immediately available for comment at the time of writing.
“In addition, our analysis suggests that more information could be collected by calling various PDF Javascript APIs. For example, the document’s location on the system could be obtained by calling the Javascript “this.path” value,” Li added.
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.”
3G And 4G Modems Pose Security Threats
Researchers Nikita Tarakanov and Oleg Kupreev analyzed the security of 3G/4G USB modems obtained from Russian operators for the past several months. Their findings were presented Thursday at the Black Hat Europe 2013 security conference in Amsterdam.
Most 3G/4G modems used in Russia, Europe, and probably elsewhere in the world, are made by Chinese hardware manufacturers Huawei and ZTE, and are branded with the mobile operators’ logos and trademarks, Tarakanov said. Because of this, even if the research was done primarily on Huawei modems from Russian operators, the results should be relevant in other parts of the world as well, he said.
Tarakanov said that they weren’t able to test baseband attacks against the Qualcomm chips found inside the modems because it’s illegal in Russia to operate your own GSM base station if you’re not an intelligence agency or a telecom operator. “We’ll probably have to move to another country for a few months to do it,” he said.
There’s still a lot to investigate in terms of the hardware’s security. For example, the SoC (system on a chip) used in many modems has Bluetooth capability that is disabled from the firmware, but it might be possible to enable it, the researcher said.
For now, the researchers tested the software preloaded on the modems and found multiple ways to attack it or to use it in attacks.
For one, it’s easy to make an image of the USB modem’s file system, modify it and write it on the modem again. There’s a tool available from Huawei to do modem backup and restore, but there are also free tools that support modems from other manufacturers, Tarakanov said.
Malware running on the computer could detect the model and version of the active 3G modem and could write an image with malicious customizations to it using such tools. That modem would then compromise any computer it’s used on.
The researchers also found a possible mass attack vector. Once installed on a computer, the modem application — at least the one from Huawei — checks periodically for updates from a single server, Tarakanov said. Software branded for a specific operator searchers for updates in a server directory specific to that operator.
An attacker who manages to compromise this update server, can launch mass attacks against users from many operators, Tarakanov said. Huawei 3G modems from several different Russian operators used the same server, but there might be other update servers for other countries, he said.
Research in this area is just at the beginning and there’s more to investigate, Tarakanov said. Someone has to do it because many new laptops come with 3G/4G modems directly built in and people should know if they’re a security threat.
Is Android Safer Than iOS?
The general consensus is that iOS apps tend to be somewhat safer than their Android counterparts. Apple goes to great lengths to have apps vetted and as a result far fewer iOS apps end up with malware or security issues.
However, a new report fresh out of Appthority claims iOS apps have their fair share of issues and in some respects then can pose an even greater security risk than Android apps. The report covered the top 50 apps from the Apple App Store and Google Play and found that iOS apps exhibited riskier behaviour.
“The majority of iOS apps track for location (60%), share data with advertising or analytics networks (60%) and have access to the user’s contact list (54%). A small percentage of iOS apps also had access to the user’s calendar (14%),” the report found.
However, Android fans shouldn’t be too happy since their platform is not far behind. Half of them share data with ad networks or analytics companies, while 42 percent tracked location. Slightly better, but nothing to be proud about.
One of the most worrying findings is that both Android and iOS apps don’t do much to prevent personal data from leaking from our devices. Not a single iOS app analyzed in the study used encryption to send and receive data, and neither did 92 percent of Android apps.
So while it might seem that Android is a somewhat better platform for users with privacy concerns, both Google and Apple are pants at that sort of thing.
