Is Automation the Key to Lower Incident Response Times?

This year’s SANS Endpoint Security Survey report is loaded with interesting statistics such as:

  • 42% of IT professionals acknowledged they had suffered a breach on their endpoints.
  • 20% said they did not know if they had been breached.
  • 82% of those that knew of a breach said it had involved a desktop.
  • 69% cited corporate laptops.
  • 42% cited employee-owned laptops.
  • 47% of antivirus capabilities detected threats.
  • 26% of breaches were detected by endpoint detection and response (EDR) capabilities.

It was this last response that was of particular interest, so we took a deeper dive.

Endpoints Up Response Times Down

One of the challenges facing security professionals is the seemingly ever expanding number of endpoints that need to be monitored. It’s akin to having an ever expanding fence line that needs to be patrolled and maintained by a rancher to prevent loss of livestock to predators.

 

Interestingly enough, despite the growth in endpoints this year’s report showed that incident response times are actually decreasing. One of the primary reasons for this is automated endpoint detections and response capabilities (EDR).

Are you Automated?

 

If you have purchased and fully implanted a next-gen EDR solution you can consider yourself and your organization firmly ahead of the curve.  As SANS Analyst and survey author Lee Neely states in the report:

 

“The diversity and quantity of endpoints in the modern enterprise are driving the need for more automation and predictive capabilities. While [organizations] are purchasing solutions to keep ahead of the emerging cyber threats, they appear to fall short on implementing the key purchased capabilities needed to protect and monitor the endpoint.”

In fact, to be more specific:

“Of the IT professionals that had acquired next-gen endpoint security solutions, 37% haven’t implemented their full capabilities”.

Let Konsultek Help You Automate

The SANS Incident Response Survey shows that the largest number of respondents had a “time to detect” between 6-24 hours, “time to contain” of 2-7 days and  finally a “time to remediate” of 2-7 days.  As security professionals looking to secure an ever more complex end-point “fence line” how do we accelerate the incident response time? The obvious answer is to use machine based automation.

Curious as to how that might work in your organization’s network? We’d be happy to explain! Just give us a call to discuss how a Konsultek custom security solution can take your organization to a whole new level of security.

 

22Line Code “Scalpel” to Removes British Airways Customer Data

A couple weeks ago British Airways confirmed that the personal data of 380,000 customers had been stolen.

Magecart Again. Still?

On September 11th the simplicity of this surgical strike was revealed by RiskIQ and the details are pretty amazing. According to RiskIQ the incident, which lasted 15 days, was very similar to the breach of Ticket Master UK earlier in the year. That similarity combined with crawl data allowed them to quickly confirm that the threat actors were one in the same, Magecart.

Magecart is a group of criminals that specialize in web based credit card skimmers. RiskIQ actively monitors 2 billion pages of the world wide web for Magecart activity and Magecart is so active that RiskIQ gets hourly notifications of sites being hacked!

The 22 Line Scalpel

In the case of the British Airways hack, Magecart slightly modified their code so it went unnoticed by the RiskIQ automated crawlers and only after the fact could RiskIQ manually identify their handiwork. It turned out that the 22 lines of javascript shown below is what excised the personal data of 380,000 customers.

The same code also appears to have affected the British Airways mobile app for the same period of time. This is because the app was developed as an empty shell that simply pulled in functionality from the desktop site. While past Magecart attacks grabbed form data indiscriminately, these 22 lines were highly targeted, extracting payment information and sending it off to their own servers.

While WannaCry is Making Headlines Docusign Breach Quietly Endangers Users

Rather than write the 1000th post about WannaCry (although our Partners at Proofpoint, their Engineer Darien Huss and a fellow called MalwareTech deserve a serious shout-out from the world for stopping WannaCry) I decided to cover something with potentially huge financial implications that has virtually gone under the radar by comparison.

While WannaCry was grabbing the cybersecurity headlines for the week, it turns out that online signature giant DocuSign was more quietly and in a rather methodical fashion, publicly disclosing the details of a significant and serious cyberbreach themselves.

Here’s an abbreviated timeline of what we know so far from DocuSign themselves.

Update 5/9/2017 – Malicious Email Campaign

DocuSign is tracking a malicious email campaign where the subject reads: “Completed: docusign.com – Wire Transfer Instructions for recipient-name Document Ready for Signature”.

The email contains a link to a downloadable Word Document which is designed to trick the recipient into running what’s known as macro-enabled-malware.

Update 5/15/2017 – Malicious Email Campaign

DocuSign is tracking a malicious email campaign where the subject reads: Completed *company name* – Accounting Invoice *number* Document Ready for Signature;The email contains a link to a downloadable Word Document which is designed to trick the recipient into running what’s known as macro-enabled-malware.

These emails are not associated with DocuSign. They originate from a malicious third-party using DocuSign branding in the headers and body of the email. The emails are sent from non-DocuSign-related domains including dse@docus.com. Legitimate DocuSign signing emails come from @docusign.com or @docusign.net email addresses.

Update 5/15/2017 – Latest update on malicious email campaign

Last week and again this morning, DocuSign detected an increase in phishing emails sent to some of our customers and users – and we posted alerts here on the DocuSign Trust Site and in social media. The emails “spoofed” the DocuSign brand in an attempt to trick recipients into opening an attached Word document that, when clicked, installs malicious software. As part of our process in response to phishing incidents, we confirmed that DocuSign’s core eSignature service, envelopes and customer documents remain secure.

However, as part of our ongoing investigation, today we confirmed that a malicious third party had gained temporary access to a separate, non-core communication system used for service-related announcements that contained a list of email addresses. A complete forensic analysis has confirmed that only email addresses were accessed; no names, physical addresses, passwords, social security numbers, credit card data or other information was accessed. No content or any customer documents sent through DocuSign’s eSignature system was accessed; and DocuSign’s core eSignature service, envelopes and customer documents and data remain secure.

Update 5/16/2017 @ 8:55 Pacific Time – Key Update on Malicious Campaign

Q: Have the email addresses of my employees, customers or customers’ customers been exposed as part of this incident?
A: As part of our ongoing investigation, we can now confirm that no signers were on the list of email addresses that was accessed maliciously unless they had signed up for a DocuSign account. That could include direct DocuSign customers; someone who signed a document and elected to open a DocuSign account; or someone who signed up for a DocuSign freemium account – via docusign.com, through a partner integration, or via the DocuSign mobile client.

Update 5/17/2017 @ 1:02 PM Pacific Time – New Phishing Campaign Discovered Today

DocuSign has observed a new phishing campaign that began the morning of May 16 (Pacific Time). The email comes from “dse@dousign.com” with the subject “Legal acknowledgement for <person> Document is Ready for Signature” and it contains a link to a malicious, macro-enabled Word document. We suggest you do not open this email, but rather delete it immediately.

The Ultimate Phishing Scam?

This may very well be the ultimate spear phishing campaign. While the number of email addresses compromised has not been disclosed, we can assume it is A LOT and a considerable portion of those affected routinely use DocuSign multiple times a month, if not weekly or daily. Since DocuSign emails are both expected and “trusted” we can only further assume that these phishing campaigns are being effective. No official report on just how effective, so far, but perhaps we’ll get an update further details emerge.

It seems likely that this scam will continue for a very long time given that DocuSign reportedly has 100 million users.

The Lesson You Can Learn

“However, as part of our ongoing investigation, today we confirmed that a malicious third party had gained temporary access to a separate, non-core communication system used for service-related announcements that contained a list of email addresses.” (Emphasis added)

The lesson to be learned here is that in today’s world no part of your network can be considered “non-core” when it comes to security. If the data is worth saving within your network, it is worth protecting!

2017 Cisco Annual Cybersecurity Report Insights

The 2017 Cisco Annual Cybersecurity report was just published. Weighing in at 110 pages and filled with detailed analysis, this is a report that should be downloaded and reviewed by anyone with an interest in the ever changing cybersecurity landscape.

Here are some of the major findings outlined in the report:

● The top constraints to adopting advanced security products and solutions, according to the benchmark study, are budget (cited by 35 percent of the respondents), product compatibility (28 percent), certification (25 percent), and talent (25 percent).

● The Cisco 2017 Security Capabilities Benchmark Study found that, due to various constraints, organizations can investigate only 56 percent of the security alerts they receive on a given day. Half of the investigated alerts (28 percent) are deemed legitimate; less than half (46 percent) of legitimate alerts are remediated. In addition, 44 percent of security operations managers see more than 5000 security alerts per day.

● Twenty-seven percent of connected third-party cloud applications introduced by employees into enterprise environments in 2016 posed a high security risk. Open authentication (OAuth) connections touch the corporate infrastructure and can communicate freely with corporate cloud and software-as-a-service (SaaS) platforms after users grant access.  See our previous post on private vs. public cloud

● According to the Security Capabilities Benchmark Study, organizations that have not yet suffered a security breach may believe their networks are safe. This confidence is probably misplaced, considering that 49 percent of the security professionals surveyed said their organizations have had to manage public scrutiny following a security breach. 6 Executive Summary and Major Findings Cisco 2017 Annual Cybersecurity Report

● The Cisco 2017 Security Capabilities Benchmark Study also found that nearly a quarter of the organizations that have suffered an attack lost business opportunities. Four in 10 said those losses are substantial. One in five organizations lost customers due to an attack, and nearly 30 percent lost revenue.

● When breaches occur, operations and finance were the functions most likely to be affected (36 percent and 30 percent, respectively), followed by brand reputation and customer retention (both at 26 percent), according to respondents to the benchmark study.

● Network outages that are caused by security breaches can often have a long-lasting impact. According to the benchmark study, 45 percent of the outages lasted from 1 to 8 hours; 15 percent lasted 9 to 16 hours, and 11 percent lasted 17 to 24 hours. Fortyone percent (see page 55) of these outages affected between 11 percent and 30 percent of systems. See our recent post on Business Continuity

● The 2017 Security Capabilities Benchmark Study found that most organizations rely on third-party vendors for at least 20 percent of their security, and those who rely most heavily on these resources are most likely to expand their use in the future. Review Konsultek’s Managed Security Services
