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?
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.
