Cyber Attacks Increasing In Middle East
Comments Off on Cyber Attacks Increasing In Middle East
Syria’s civil war and political strife in Egypt have given birth to new battlegrounds on the Web and driven a surge in cyber attacks in the Middle East, according to a leading Internet security company.
More than half of incidents in the Gulf this year were so-called “hacktivist” attacks – which account for only a quarter of cybercrime globally – as politically motivated programmers sabotaged opposing groups or institutions, executives from Intel Corp’s software security division McAfee said on Tuesday.
“It’s mostly bringing down websites and defacing them with political messages – there has been a huge increase in cyber attacks in the Middle East,” Christiaan Beek, McAfee director for incident response forensics in Europe, Middle East and Africa (EMEA), told Reuters.
He attributed the attacks to the conflict in Syria, political turmoil in Egypt and the activities of hacking collective Anonymous.
“It’s difficult for people to protest in the street in the Middle East and so defacing websites and denial of service (DOS) attacks are a way to protest instead,” said Beek.
DOS attacks flood an organization’s website causing it to crash, but usually do little lasting damage.
The Syrian Electronic Army (SEA), a hacking group loyal to the government of President Bashar al-Assad, defaced an Internet recruiting site for the U.S. Marine Corps on Monday and recently targeted the New York Times website and Twitter, as well other websites within the Middle East.
Beek described SEA as similar to Anonymous.
“There’s a group leading operations, with a support group of other people that can help,” said Beek.
McAfee opened a centre in Dubai on Monday to deal with the rising threat of Internet sabotage in the region, the most serious of which are attacks to extract proprietary information from companies or governments or those that cause lasting damage to critical infrastructure.
Cyber attacks are mostly focused on Saudi Arabia, the world’s largest oil exporter, Qatar, the top liquefied natural gas supplier, and Dubai, which is the region’s financial, commercial and aviation hub, said Gert-Jan Schenk, McAfee president for EMEA.
“It’s where the wealth and critical infrastructure is concentrated,” he said.
The “Shamoon” virus last year targeted Saudi Aramco, the world’s largest oil company, damaging about 30,000 computers in what may have been the most destructive attack against the private sector.
“Ten years ago, it was all about trying to infect as many people as possible,” added Schenk. “Today we see more and more attacks being focused on very small groups of people. Sometimes malware is developed for a specific department in a specific company.”
Collaborating Viruses Showing Up
Two computer viruses are collaborating to defeat clean-up operations. Microsoft researcher Hyun Choi has found that the pair of viruses foil removal by regularly downloading updated versions of their malware partner.
It is the first time that such a defense plan has been noticed before. Choi said that the Vobfus and Beebone viruses, were regularly found together. Vobfus was the first to arrive on a machine, he said, and used different tactics to infect victims. Vobfus could be installed via booby-trapped links on websites, travel via network links to other machines or lurk on USB drives and infect machines they are plugged into.
Once installed, Vobfus downloaded Beebone which enrolled the machine into a botnet. After this the two start to work together to regularly download new versions of each other. If Vobfus was detected and remediated, it could have downloaded an undetected Beebone which can in turn download an undetected variant of Vobfus.
Vobfus become a persistent problem since 2009 when it first appeared.

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.
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.
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.”
Microsoft’s Vista Infection Rates Climb
Microsoft said last week that an uptick in more security exploits on Windows Vista can be attributed to the demise of support for the operating system’s first service pack.
Data from the company’s newest security intelligence report showed that in the second half of 2011, Vista Service Pack 1 (SP1) was 17% more likely to be infected by malware than Windows XP SP3, the final upgrade to the nearly-11-year-old operating system.
That’s counter to the usual trend, which holds that newer editions of Windows are more secure, and thus exploited at a lower rate, than older versions like XP. Some editions of Windows 7, for example, boast an infection rate half that of XP.
Tim Rains, the director of Microsoft’s Trustworthy Computing group, attributed the rise of successful attacks on Vista SP1 to the edition’s retirement from security support.
“This means that Windows Vista SP1-based systems no longer automatically receive security updates and helps explain why there [was] a sudden and sharp increase in the malware infection rate on that specific platform,” said Rains in a blog post last week.
AES Encryption Cracked
CRYPTOGRAPHY RESEARCHERS have identified a weakness in the Advanced Encryption Standard (AES) security algorithm that can crack secret keys faster than before.
The crack is the work of a trio of researchers at universities and Microsoft, and involved a lot of cryptanalysis – which is somewhat reassuring – and still does not present much of a real security threat.
Andrey Bogdanov, from K.U.Leuven (Katholieke Universiteit Leuven), Dmitry Khovratovich, who is full time at Microsoft Research, and Christian Rechberger at ENS Paris were the researchers.
Although there have been other attacks on the key based AES security system none have really come close, according to the researchers. But this new attack does and can be used against all versions of AES.
This is not to say that anyone is in immediate danger and, according to Bogdanov, although it is four times easier to carry out it is still something of an involved procedure.
Recovering a key is no five minute job and despite being four times easier than other methods the number of steps required to crack AES-128 is an 8 followed by 37 zeroes.
“To put this into perspective: on a trillion machines, that each could test a billion keys per second, it would take more than two billion years to recover an AES-128 key,” the Leuven University researcher added. “Because of these huge complexities, the attack has no practical implications on the security of user data.” Andrey Bogdanov told The INQUIRER that a “practical” AES crack is still far off but added that the work uncovered more about the standard than was known before.
“Indeed, we are even not close to a practical break of AES at the moment. However, our results do shed some light into the internal structure of AES and indicate where some limits of the AES design are,” he said.
He added that the advance is still significant, and is a notable progression over other work in the area.
“The result is the first theoretical break of the Advanced Encryption Standard – the de facto worldwide encryption standard,” he explained. “Cryptologists have been working hard on this challenge but with only limited progress so far: 7 out of 10 for AES-128 as well as 8 out of 12 for AES-192 and 8 out of 14 rounds for AES-256 were previously attacked. So our attack is the first result on the full AES algorithm.”
“TDL-4″ Botnet Is Practically Indestructible
Comments Off on “TDL-4″ Botnet Is Practically Indestructible
A new and improved botnet that has infected more than four million computers is “practically indestructible,” software security experts say.
“TDL-4,” the name for both the bot Trojan that infects PCs and the ensuing collection of compromised computers, is “the most sophisticated threat today,” said Kaspersky Labs researcher Sergey Golovanov in a detailed analysis Monday.
“[TDL-4] is practically indestructible,” Golovanov said and others agree.
“I wouldn’t say it’s perfectly indestructible, but it is pretty much indestructible,” said Joe Stewart, director of malware research at Dell SecureWorks and an internationally-known botnet expert, in an interview today. “It does a very good job of maintaining itself.”
Golovanov and Stewart based their assessments on a variety of TDL-4′s traits, all which make it an extremely tough character to detect, delete, suppress or eradicate.
Because TDL-4 installs its rootkit on the Master Boot Record (MBR), it is invisible to both the operating system and more, importantly, security software designed to sniff out malicious code.
Further,what makes the botnet indestructible is the combination of its advanced encryption and the use of a public peer-to-peer (P2P) network for the instructions issued to the malware by command-and-control (C&C) servers.
“The way peer-to-peer is used for TDL-4 will make it extremely hard to take down this botnet,” said Roel Schouwenberg, senior malware researcher at Kaspersky, ”The TDL guys are doing their utmost not to become the next gang to lose their botnet.”
Microsoft Delivers Massive Security Updates
Comments Off on Microsoft Delivers Massive Security Updates
Microsoft today patched a whopping 64 vulnerabilities in Windows, Office, Internet Explorer (IE), and other software, including 30 bugs in the Windows kernel device driver and one in IE that was exploited at the Pwn2Own hacking contest last month.
The company also delivered a long-discussed “backport” to Office 2003 and Office 2007 that brings one of the newer security features in Office 2010 to the older editions.
The 17 updates, which Microsoft dubs “bulletins,” tied a record set late last year, but easily beat the October 2010 mark for the total number of flaws they fixed. Altogether, today’s updates patched 64 vulnerabilities, 15 more than in October and 24 more than in the former second-place collection of December 2010.
Nine of the 17 bulletins were pegged “critical,” Microsoft’s highest threat ranking, while the remainder were marked “important,” the next-most-serious label.
Microsoft and virtually every security expert pegged several updates that users should download and install immediately.
“There are three we think are top priorities,” said Jerry Bryant, group manager with the Microsoft Security Response Center (MSRC), in an interview earlier today. Bryant tagged MS11-018, MS11-019 and MS11-020 as the ASAP updates.
