Today Norman and the Shadowserver Foundation released a joint detailed report dubbed Operation Hangover, which relates to a recently released ESET blog about a targeted cyber/espionage attack that appears to be originating from India. Symantec released a brief blog around this incident last week and this Q&A will provide additional information relevant to Symantec around this group.

Q: Do Symantec and Norton products protect against threats used by this group?
Yes. Symantec confirms protection for attacks associated with Operation Hangover through our antivirus and IPS signatures, as well as STAR malware protection technologies...

Today, Trend Micro published a report about a targeted attack campaign they’re calling SafeNet (the campaign’s name is unrelated to the security company of the same name). The group behind this campaign is utilizing spear phishing emails with malicious attachments. These attachments are document files that exploit vulnerabilities in Microsoft Word. Some of the documents we’ve observed exploit the Microsoft Windows Common Controls ActiveX Control Remote Code Execution Vulnerability (CVE-2012-0158).

If exploitation is successful, the malicious documents drop the following files:

  • smcs.exe
  • SafeExt.dll
  • SafeExt.org
  • SafeCredential.DAT

SafeExt.dll contains most of the threat’s functionality while SafeCredential.DAT...

ESET recently blogged about a targeted cyber/espionage attack that appears to be originating from India. Multiple security vendors have been tracking this campaign. The attack appears to be no more than four years old and very broad in scope. Based on our telemetry (Figure 1), it appears that attackers are focusing on targets located in Pakistan, specifically government agencies.

The identified infection vector of this campaign is spear phishing emails with malicious files attached. We’ve observed malicious documents exploiting the Microsoft Windows Common Controls ActiveX Control Remote Code...

As the urban legend goes, the bank robber Willie Sutton was asked why he robbed banks. “Because that’s where the money is,” he is attributed as saying. While Sutton has long since distanced himself from the statement, the concept resonates with many people, to the extent that it’s been used to describe principles in accounting and even medicine.  

This principle also holds true in the world of Internet security. In the latest version of the Internet Security Threat Report we discussed the major trends in the spam world, where the percent of spam email continues to decline while more and more social networks are being targeted. Given the growth of social networking in recent years as a means to communicate, this...

Since the beginning of the year, a Japanese one-click fraud campaign has continued to wreak havoc on Google Play. The scammers have published approximately 700 apps in total since the end of January. The apps are published on a daily basis and the scammers have invested around US$4,000 in order to pay the US$25 developer fee to publish apps on Google Play.

Dealing with the fraudulent apps has really become a game of cat and mouse. Once the apps are removed from Google Play, the scammers simply publish more under new developer accounts. These are again removed shortly afterwards, but the scammers simply continue to publish more. Most of the apps are removed on the date of publication,...

In April 2013, Symantec was alerted to a series of sophisticated social-engineering attacks targeting a limited set of organizations in Europe. The most distinguishing feature of these attacks is that the victim will receive a phone call from the attacker who impersonates an employee or business associate of the organization. The caller spoke in French and asked the victim to process an invoice that they were to receive in an email.

Here is an example of an email that was received during one of the attacks. The email typically contains a malicious link or an attachment, which is actually a variant of W32.Shadesrat, a Remote Access Trojan (RAT).

In the last few months, we have witnessed a rise in the number of cases of modified Web servers that inject malicious redirections into every website that it hosts. One example was the malicious Apache module (Linux.Chapro and Trojan.Apmod) that we blogged about recently. A newer example is Linux.Cdorked, about which our friends at ESET also wrote.

With Linux.Cdorked, instead of adding a malicious Apache module to the configuration list, the attackers instead replaced the main httpd binary file...

Following on from recent concerted campaigns by Anonymous against Israel on April 7 and Facebook on April 5, the latest target for the online hacktivist collective is the USA and American online interests. Today, hackers and script kiddies of various affiliations are expected to begin a campaign of hack attacks and general online disruption against any target that is related to the USA. From previous activity of this sort, the attackers are generally opportunistic in nature and will aim for the low hanging fruit. Attacks may take various forms including the following:

  • DDoS attacks
  • Hack social media accounts and deface or post fake messages
  • Hack organization websites and deface or steal information and post it as “proof” of breach
  • Hack organization servers and attempt sabotage such as planting disk wiping malware
  • Less likely but plausible scenarios could include attacks against...

Microsoft has issued Security Advisory 2847140 in response to reports regarding public exploitation of a vulnerability affecting Internet Explorer 8. Other versions such as Internet Explorer 6, Internet Explorer 7, Internet Explorer 9, and Internet Explorer 10 are not affected. Initial reports indicate that a website associated with a department of the US government was compromised to host the exploit in what’s known as a watering hole attack. Upon visiting the site a vulnerable victim would have been redirected to download a back door as the payload.  Symantec products detect the exploit code on the vulnerable site as Trojan.Malscript, Bloodhound.Exploit.494, or...
