Can OSX Make Macs Vulnerable To Rootkits?

Comments Off on Can OSX Make Macs Vulnerable To Rootkits?

The software genii at Apple have redesigned their OSX software to allow malware makers to make designer micro-software that can infect Macs with rootkits.

Obviously the feature is one that Apple software experts designed specifically for malware writers, perhaps seeing them as an untapped market.

The bug in the latest version of Apple’s OS X allows attackers root user privileges with a micro code which could be packed into a message.

Security researcher Stefan Esser said that this was the security hole attackers regularly exploit to bypass security protections built into modern operating systems and applications.

The OS X privilege-escalation flaw stems from new error-logging features that Apple added to OS X 10.10. Plainly the software genii did not believe that standard safeguards involving additions to the OS X dynamic linker dyld applied to them because they were protected from harm by Steve Job’s ghost.

This means that attackers to open or create files with root privileges that can reside anywhere in the OS X file system.

“This is obviously a problem, because it allows the creation or opening (for writing) of any file in the filesystem. And because the log file is never closed by dyld and the file is not opened with the close on exec flag the opened file descriptor is inherited by child processes of SUID binaries. This can be easily exploited for privilege-escalation,” Esser said.

The vulnerability is present in both the current 10.10.4 (Yosemite) version of OS X and the current beta version of 10.10.5. Importantly, the current beta version of 10.11 is free of the flaw, an indication that Apple developers may already be aware of the vulnerability.

An Apple spokesman said that engineers are aware of Esser’s post of course they did not say they would do anything about it. They will have to go through the extensional crisis involved in realising that their product was not secure or perfect. Then the security team will have to issue orders, signed in triplicate, sent in, sent back, queried, lost, found, subjected to an internal inquiry, lost again, and finally bury it in soft peat for three months and recycled as firelighters.

Is Unity Up to Something Big?

Comments Off on Is Unity Up to Something Big?

Earlier today Unity Technologies caused quite a stir in the games industry with the announcement that former Electronic Arts chief exec John Riccitiello would be taking over the CEO job for David Helgason. While EA struggled to make shareholders happy, Unity has been seeing tremendous growth, becoming a favorite toolset for large and small publishers and especially indies. In fact, the company serves over 600,000 monthly developers. But what does Unity really have up its sleeve? Is the hiring of a notable leader like Riccitiello a sign that the company is indeed being groomed for a buyout or public offering?

“John Riccitiello’s corporate moves will rightfully inspire speculation about major changes in the companies involved and as Unity is the dominant independent development platform, what happens next could affect most developers and publishers outside of the top ten,” remarked independent analyst Billy Pidgeon. “An acquisition is very possible although Unity CTO Joachim Ante has denied this. Unity needs to be independent and available to all to retain and grow its value, so a sale to a major publisher or developer would sharply decrease the company’s revenue flow. But a buyer outside the industry could allow Unity to remain somewhat independent, although clients might be wary of doing business with Unity’s new owner.”

EEDAR’s Patrick Walker, head of insights and analytics, largely agreed with Pidgeon, commenting, “While the stature of Riccitiello as a hire and his interest in helming the Unity ship suggest that there are big plans in the works for the company, it is unlikely that these plans are focused on the short term, such as preparation for a near-term buyout. A buyout has been rumored for a while, and the Unity executive team, including founder David Helgason and CTO Joachim Ante, has been consistent in their messaging statement focusing on the company mission rather than pursuit of a buyout. More likely, Riccitiello is being brought on board to spur growth for a longer-term play, such as an eventual IPO or larger-scale buyout.”

Regardless of whether a longer-term buyout is in the cards, Riccitiello has the experience to help accelerate Unity’s growth in the next few years, most believe.

“Unity is a well-positioned company with several paths to increase growth. While game publishing is one route to spur growth, there is also an opportunity for the company to leverage the strengths, such as cross-platform flexibility, that have given it such broad penetration in the indie market to increase penetration in other development verticals,” Walker continued. “Riccitiello has an ideal background, having led major companies both inside and outside the games industry and having served on the Unity board for the past year, to drive partnerships that will help grow Unity as a major development platform across the full spectrum of publishers and developers.”

Wedbush Securities’ Michael Pachter added, “He is certainly capable of leading them, and also well equipped to sell the company. [But] I don’t know the reason for the change.”

Perhaps one major reason for the change is to offload some of the business responsibility from Helgason who may wish to focus more on product development.

“Unity has been growing quickly for several years. The company now has over 300 employees and its technology is being used by hundreds of thousands of developers on practically every platform out there. I suspect that Dave recognized some time ago that the company had to get an experienced business manager at the helm or risk flying off the rails at some point, and that’s exactly what JR is,” observed Lewis Ward, IDC’s gaming research director.

“Some people just aren’t cut out to be CEOs of big businesses – just look at Notch. I suspect that Dave is going to be happier staying focused on the core product strategy and building relationships with studios and indie developers. From JR’s perspective, it’s a great opportunity to ride the beast that has been Unity growth over the past 3+ years. It’s a remarkable story, and I think John is probably going to enjoy the role and stepping back into an important spotlight in the industry.”

Is Epic Turla Exploiting Windows XP?

Comments Off on Is Epic Turla Exploiting Windows XP?

Kaspersky Lab has discovered an espionage network that successfully attacked government institutions, intelligence agencies and European companies.

The firm has dubbed the spy operation Epic Turla, and said that it is in no doubt about its capabilities.

“Over the last 10 months, Kaspersky Lab researchers have analyzed a massive cyber-espionage operation which we call ‘Epic Turla’,” it said.

“The attackers behind Epic Turla have infected several hundred computers in more than 45 countries, including government institutions, embassies, military, education, research and pharmaceutical companies.”

Kaspersky said that Epic Turla used two zero-day exploits that affected Adobe and Microsoft software, along with some backdoor and social engineering tricks.

In particular, Kaspersky said a vulnerability in Windows XP and Windows 2003 – CVE-2013-5065 – termed a “privilege escalation vulnerability” is being used. “The CVE-2013-5065 exploit allows the backdoor to achieve administrator privileges on the system and run unrestricted. This exploit only works on unpatched Microsoft Windows XP systems.”

The use of this Windows XP flaw underlines the risk that the unsupported Windows XP OS poses. Kaspersky went on to explain that, once inside, attackers install their own rootkits and other malware tools and begin their surveillance.

“Once the attackers obtain the necessary credentials without the victim noticing, they deploy the rootkit and other extreme persistence mechanisms,” it said. “The attacks are still ongoing as of July 2014, actively targeting users in Europe and the Middle East.”

The attacks are just the latest in a long line of incidents that businesses need to be aware of as cyber attacks continue at an alarming rate.

In June the security firm Crowdstrike alerted the industry to Putter Panda, a cute-sounding but nasty piece of malware. That firm pointed an accusatory finger at China and charged it with espionage on the US and Europe.

Crowdstrike CEO George Kurtz said at the time, “China’s decade-long economic espionage campaign is massive and unrelenting. Through widespread espionage campaigns, Chinese threat actors are targeting companies and governments in every part of the globe.” Chinese authorities disputed this.

The report comes in the same week Hold Security reported uncovering a huge trove of 1.2 billion web passwords and login details that have been gathered by Russian cyber criminals.

Is Malware Wreaking Havoc On XP?

Comments Off on Is Malware Wreaking Havoc On XP?

One of the top three malware programs affecting businesses in the second quarter is a worm that takes advantage of the large number of companies still using Windows XP, Trend Micro has warned.

The worm, dubbed DOWNAD, also known as Conficker, can infect an entire network via a malicious URL, spam email, or removable drive. Windows XP is particularly susceptible to this threat because it is known to exploit the MS08-067 Server service vulnerability in order to execute arbitrary code.

DOWNAD also has its own domain generation algorithm (DGA) that allows it to create randomly-generated URLs. It then connects to these created URLs to download files to the system. Trend Micro said that around 175 IP addresses are found to be related to the DOWNAD worm and that these IP addresses use various ports and are randomly generated via the DGA capability of DOWNAD.

“During our monitoring of the spam landscape, we observed that in Q2, more than 40 percent of malware related spam mails are delivered by machines infected by DOWNAD worm,” said Trend Micro anti-spam research engineer Maria Manly in a blog post.

“A number of machines are still infected by this threat and leveraged to send the spammed messages to further increase the number of infected systems. And with Microsoft ending the support for Windows XP this year, we can expect that systems with this OS can be infected by threats like DOWNAD.”

The security company warned that spam campaigns delivering FAREIT, MYTOB, and LOVGATE payloads in email attachments are attributed to DOWNAD infected machines. FAREIT is a malware family of information stealers that download variants of the Zeus Trojan, while MYTOB is an old family of worms known for sending a copy of itself in spam attachments.

The other top sources of spam with malware are the CUTWAIL botnet, together with Gameover ZeuS (GoZ). Manly said CUTWAIL was actually previously used to download GoZ malware but now a malware called UPATRE employs GoZ malware or variants of ZBOT which have peer-to-peer functionality.

“In the last few weeks we have reported various spam runs that abused Dropbox links to host malware like UPATRE,” Manly said. “We also spotted a spammed message in the guise of voice mail that contains a Cryptolocker variant. The latest we have seen is a spam campaign with links that leveraged CUBBY, a file storage service, this time carrying a banking malware detected as TSPY_BANKER.WSTA.”

According to Manly, cybercriminals and threat actors are probably abusing file storage platforms to mask their malicious activities and go undetected in the system and network.

“As spam with malware attachment continues to proliferate, so is spam with links carrying malicious files. The continuous abuse of file hosting services to spread malware appears to have become a favoured infection vector of cyber criminals most likely because this makes it more effective given that the URLs are legitimate thereby increasing the chance of bypassing anti-spam filters,” she added.

Can Malwarebytes Protect XP?

Comments Off on Can Malwarebytes Protect XP?

Malwarebytes has launched anti-exploit services to protect Windows users from hacking attacks on vulnerabilities in popular targets including Microsoft Office, Adobe software products and Java, a service which even offers protection for Windows XP users.

Consumer, Premium and Corporate versions of the service are available, and are designed to pre-emptively stop hackers from infecting Windows machines with malware.

“An exploit will typically first corrupt the memory of an application process, take control, then execute code,” said Malwarebytes director of special projects Pedro Bustamante.

“From the shell code it executes a payload that tells the exploit what to do and that in turn usually downloads malware from the internet and executes it. The final stage is usually where antivirus kicks in, when it’s being downloaded from the internet, and starts doing things like behavioural analysis to see if it’s malicious.

“We don’t care about that, what we do comes before then. We just look for exploit-like behaviour and block anything that looks like it at the shellcode or payload stages. We come into play before the malware even appears on the scene.”

The Consumer version of the anti-exploit service is free and offers basic browser and Java protection.

The Premium version costs $37.00  per user and adds Office and Adobe protection services as well as the ability to add custom shields to other internet-facing applications, like Messenger or Netflix.

The Corporate version costs$40.00 person user and offers complete anti-exploit protection and comes with Malwarebytes’ Anti-malware service and a toolkit for IT managers.

Bustamante explained that the technology is designed to help businesses and general web users defend against the new wave of exploit-based cyber attacks.

“Traditional security can’t deal with exploits. Every day we see people getting infected, even if they have the latest up-to-date antivirus readers, because of exploits,” he said. “This is why we care about the applications you run – Firefox, Chrome, Internet Explorer, Java, Acrobat [and Microsoft] Word, Excel [and] Powerpoint.”

Bustamante added that the service is doubly important for Windows XP users since Microsoft officially ceased support for the OS in April.

“We’re still seeing over 25 percent of our users running XP. For them this product is even more important,” he said.

“We see new zero-days if not every week, every month, and for XP users who are not getting any more patches from Microsoft this product will be essential.

“Every month Microsoft will be releasing security patches for newer versions of Windows. Every time Microsoft does this it’ll be a treasure map for hackers to find exploits on Windows XP.

“It’ll show them exactly where the vulnerabilities are, so every month will see an influx of new exploits targeting Windows XP.”
