What happens when you open an email and allow it to display embedded images and pixels? You may expect the sender to learn that you’ve read the email, and which device you used to read it. But in a new paper we find that privacy risks of email tracking extend far beyond senders knowing when emails are viewed. Opening an email can trigger requests to tens of third parties, and many of these requests contain your email address. This allows those third parties to track you across the web and connect your online activities to your email address, rather than just to a pseudonymous cookie.

How it works. Email tracking is possible because modern graphical email clients allow rendering a subset of HTML. JavaScript is invariably stripped, but embedded images and stylesheets are allowed. These are downloaded and rendered by the email client when the user views the email.[2] Crucially, many email clients, and almost all web browsers, in the case of webmail, send third-party cookies with these requests. The email address is leaked by being encoded as a parameter into these third-party URLs.

You may know that most websites have third-party analytics scripts that record which pages you visit and the searches you make. But lately, more and more sites use “session replay” scripts. These scripts record your keystrokes, mouse movements, and scrolling behavior, along with the entire contents of the pages you visit, and send them to third-party servers. Unlike typical analytics services that provide aggregate statistics, these scripts are intended for the recording and playback of individual browsing sessions, as if someone is looking over your shoulder.

Over 400 of the World’s Most Popular Websites Record Your Every Keystroke

Prominent companies who use the scripts include men’s retailer Bonobos.com, Walgreens.com, and the financial investment firm Fidelity.com. It’s also worth noting that 482 might be a low estimate. It’s likely that the scripts don’t record every user that visits a site, the researchers told me. So when they were testing, they likely did not detect some scripts because they were not activated. You can see all the popular websites that utilize session replay scripts documented by the researchers here.

The Walgreen’s example runs afoul of HIPPA in, oh, so many ways.

List of sites discovered (I bet many, many more are doing it)

https://webtransparency.cs.princeton.edu/no_boundaries/session_replay_sites.html

Disable all scripting. Disable images. Hell, I’m almost at the point of disabling stylesheets, that’ll be the next tracker if they aint doing it already.

I guess, just use surfraw and parse the output. Or go oldschool and lynx/links.

bookmark_borderRussia Attempts to Hack Electric Grid

by Membrane Domain Cybersecurity

Malware associated with a Russian hacking operation, Grizzly Steppe, was found on a Burlington Electric computer. It appears as though Russia was trying to access the power grid; however, the infected computer was not connected to the network.

“Vermonters and all Americans should be both alarmed and outraged that one of the world’s leading thugs, Vladimir Putin, has been attempting to hack our electric grid, which we rely upon to support our quality-of-life, economy, health, and safety,” Vermont Governor Shumlin said in a statement. “This episode should highlight the urgent need for our federal government to vigorously pursue and put an end to this sort of Russian meddling.”

Senator Patrick J. Leahy said, “This is beyond hackers having electronic joy rides — this is now about trying to access utilities to potentially manipulate the grid and shut it down in the middle of winter,” Leahy said in a statement. “That is a direct threat to Vermont and we do not take it lightly.”

Representative Peter Welch said, “It’s systemic, relentless, predatory.They will hack everywhere, even Vermont, in pursuit of opportunities to disrupt our country. We must remain vigilant, which is why I support President Obama’s sanctions against Russia and its attacks on our country and what it stands for.”

According to the Department of Homeland Security:

GRIZZLY STEPPE: Russian Malicious Cyber Activity

Russia’s civilian and military intelligence services engaged in aggressive and sophisticated cyber-enabled operations targeting the U.S. government and its citizens. The U.S. Government refers to this activity as GRIZZLY STEPPE. These cyber operations included spearphishing campaigns targeting government organizations, critical infrastructure entities, think tanks, universities, political organizations, and corporations, and theft of information from these organizations. This stolen information was later publicly released by third parties.

In operations targeting other countries, including U.S. allies and partners, Russian intelligence services (RIS) have undertaken damaging or disruptive cyber-attacks, including on critical infrastructure—in some cases masquerading as third parties or hiding behind false online personas designed to cause the victim to misattribute the source of the attack.

How Do Russian Intelligence Services Operate in Cyberspace?

RIS often uses spearphishing to gain access to targeted systems (see Figure 1 below). In one 2015–16 operation (detailed in our Joint Analysis Report (JAR)), Russian cyber actors conducted a spearphishing campaign to establish presence and persistence on a target network, obtain higher-level privileges, and steal (or “exfiltrate”) information.

These actors tricked recipients into changing their passwords through a fake website that was designed by the Russians cyber actors to appear legitimate. The actors then used those credentials—the username and password—to access the network as if they were legitimate users. They installed other malicious files, moved freely throughout the target network, gathered data and information, and exfiltrated it from the target network. Russian cyber actors continue to conduct spearphishing campaigns, including one launched as recently as November 2016, just days after the U.S. election.

What is the U.S. Government Doing?

The Department of Homeland Security (DHS) and Federal Bureau of Investigation (FBI) released a Joint Analysis Report (JAR), which provides details of the tools and infrastructure used by Russian intelligence services (RIS) to compromise and exploit networks and infrastructure associated with the recent U.S. election, as well as a range of U.S. government, political, and private sector entities. The JAR also arms network defenders with the tools they need to identify, detect, and disrupt Russia’s global campaign of malicious cyber activity. We urge users and administrators to use this information to better protect your networks.

What Is Spearphishing?

Spearphishing is the use of forged emails, texts, and other messages to manipulate users into opening malware or malicious software or clicking on malicious links.

Spearphishing attacks can lead to credential theft (e.g., passwords) or may act as an entry point for threat actors into an organization to steal or manipulate data and disrupt operations.

What Information is in the JAR?

The JAR includes information on computers, servers, and other devices around the world that RIS uses to conduct command-and-control activity between compromised devices, send spearphishing emails, and steal credentials. The JAR identifies these devices by each one’s Internet Protocol (IP) address, which is a set of numbers that serves as an “address” for each computer and is used to transmit data between computers. Because RIS is using other people’s networks without their owners’ knowledge to hide their malicious activity, the computers at these IP addresses typically also host legitimate websites or other Internet services. In some cases, the cybersecurity community was aware of this infrastructure. In other cases, this information has been newly declassified by the U.S. government. The map in Figure 3 shows the 60 countries in which newly declassified IP addresses are located. The JAR also includes information on how RIS typically conducts their activities. This information can help network defenders understand how this adversary operates and can help identify new activity or disrupt ongoing intrusions by RIS.

Declassified IP Addresses by Country of Registration. United States: 47. Canada, Mexico, India, Iraq, Egypt, Turkey, Greece, Russia, Kazakhstan, Mongolia, Thailand, Cambodia, Malaysia, Indonesia, Vitenam, South Korea, Japan, Taiwan, Ukraine, Sweden, Finaldn, Poland, Slove, UK, Spaine, Italy, Austria, Poland, and Ghana: Less than 10. France: 12. Germany: 14. Netherlands: 20. China: 45.

How You Can Protect Yourself and Your Networks

A commitment to good cybersecurity and best practices is critical to protecting networks and systems. Here are some questions you may want to ask of your organization to help prevent and mitigate against attacks.

  • Backups: Do we backup all critical information? Are the backups stored offline? Have we tested our ability to revert to backups during an incident?
  • Risk Analysis: Have we conducted a cybersecurity risk analysis of the organization?
  • Staff Training: Have we trained staff on cybersecurity best practices?
  • Vulnerability Scanning and Patching: Have we implemented regular scans of our networks and systems? Do we appropriately patch known system vulnerabilities?
  • Application Whitelisting: Do we allow only approved programs to run on our networks?
  • Incident Response: Do we have an incident response plan? Have we practiced it?
  • Business Continuity: Are we able to sustain business operations without access to certain systems? For how long?
  • Penetration Testing: Have we attempted to hack into our own systems to test the security of our systems and our ability to defend against attacks?

What to Do If You See Signs of Malicious Cyber Activity

If you find signs of malicious cyber activity, we encourage you report it to DHS’s National Cybersecurity and Communications Integration Center (NCCICCustomerService@hq.dhs.gov or 888-282-0870) or the FBI through your local field office or the FBI’s Cyber Division (cywatch@ic.fbi.gov or 855-292-3937).

bookmark_borderYahoo Hacked

by Membrane Domain Cybersecurity

In September, Yahoo disclosed that 500 million user accounts had been hacked. In December 2016, Yahoo announced that an additional one billion accounts had been hacked.

“What’s most troubling is that this occurred so long ago, in August 2013, and no one saw any indication of a breach occurring until law enforcement came forward,” said Jay Kaplan, the chief executive of Synack, a security company. “Yahoo has a long way to go to catch up to these threats.”

In what could be the biggest hack ever, the Yahoo user accounts included passwords, phone numbers, birth dates, and security questions.

Verizon is in the process of buying-out Yahoo. Verizon is also known for its lackadaisical cybersecurity and has had breeches of their customer data, as well.
