Snoops Offer Security Tips

Snoops Offer Security TipsIn one of the more ironic, notice I did not say tragic, turns in the post-Snowden era, the National Security Agency (NSA) has published a report with advice for companies on how to deal with malware attacks. FierceITSecurity says the report (PDF) boils down to “prevent, detect and contain.” To be more specific, the report recommends that IT security pros:

  • Segregate networksSegregate networks so that an attacker who breaches one section is blocked from accessing more sensitive areas of the network;
  • Protect and restrict administrative privileges, in particular high-level administrator accounts, so that the attacker cannot get control over the entire network;
  • Deploy, configure, and monitor application whitelisting to prevent malware from executing;
  • Restrict workstation-to-workstation communication to reduce the attack surface for attackers;
  • Deploy strong network boundary defenses such as perimeter and application firewalls, forward proxies, sandboxing and dynamic analysis filters (PDF) to catch the malware before it breaches the network;
  • Network monitringMaintain and monitor centralized host and network logging product after ensuring that all devices are logging enabled and their logs are collected to detect malicious activity and contain it as soon as possible;
  • Implement pass-the-hash mitigation to cut credential theft and reuse;
  • Deploy Microsoft (MSFT) Enhanced Mitigation Experience Toolkit (EMET) or other anti-exploitation capability for devices running non-Windows operating systems;
  • Employ anti-virus file reputation services (PDF) to catch known malware sooner than normal anti-virus software;
  • Implement host intrusion prevent systems to detect and prevent attack behaviors; and
  • Update and patch software in a timely manner so known vulnerabilities cannot be exploited.

The author quotes from the report;

I Luv your PCOnce a malicious actor achieves privileged control of an organization’s network, the actor has the ability to steal or destroy all the data that is on the network … While there may be some tools that can, in limited circumstances, prevent the wholesale destruction of data at that point, the better defense for both industry and government networks is to proactively prevent the actor from gaining that much control over the organization’s network.

For those who have not been following along, the TLA’s have been attacking and manipulating anti-virus software from Kasperskey.

SpyingWe also now know suspect that the TLA’s have compromised at least one and probably two hardware vendors. The Business Insider recalls, way back in 2013, as part of the Edward Snowden NSA spying revelations.German publication Spiegel wrote an article alleging that the NSA had done a similar thing — put code on Juniper Networks (JNPR) security products to enable the NSA to spy on users of the equipment. 

Over at Fortinet (FTNT) they had their own backdoor management console access issue that appeared in its FortiOS firewalls, FortiSwitch, FortiAnalyzer and FortiCache devices. These devices shipped with a secret hardcoded SSH logins with a secret passphrase.

The article seems like advertising for the TLA’s hacking program.

TLA Does Good?

TLA Does Good?ZDNet reports that in the last batch of Snowden documents, there may finally be some evidence that some TLA’s were doing some good. They spied on criminals too. Apparently one Snowden document boasts of how “criminals” can be found through a TLA program.

some TLA's spied on criminals and not citizensUsing this program TLAs can identify cyber attackers. ZDNet says that malicious users causing a “distributed denial-of-service” or DDoS attack, where a group of people overload a server or network with a flood of network traffic can be traced and identified. The TLA also used its program to troll online criminal forums.

Unfortunately, for law-abiding U.S. citizens, none of the Snowden documents to date have shown that the info collected on criminals was used to stop cyber attacks or was passed on to law enforcement to take action.

Data Breach Is No Monkey Business

ReData Breach Is No Monkey Businessports are emerging that zoo’s across the nation have fallen victim to a POS attack and data breach. MLive warns anyone who made a purchase with a credit card at gift shops at the Detroit Zoo between March 23 and June 25, 2015, might be in danger of having the credit card information stolen. The Detroit Zoo posted a notice which claims that the only systems hacked were those run by Denver-based Service Systems Associates, the third-party responsible for running the systems at the Detroit Zoo’s retail stands.

Detroit ZooSSA posted a notice on their site confirming a breach but no other details. Officials are investigating data breaches of the point-of-sale systems at nine or more U.S. zoos, including the Detroit Zoo. MLive reports that hackers gained access to card holders’ names, expiration dates, CVV security codes in addition to the credit and debit card numbers.

Sources claim the malware has been since identified and removed from the systems, though the case remains under investigation. In response, A separate credit card processing system was installed after the Zoo learned of the breach. Gerry VanAcker, Detroit Zoological Society chief operating officer, said in a release:

We are obviously concerned that the vendor’s system was compromised,” s “Transactions made since June 26 are not affected by the previous breach, and it is safe to use a credit or debit card at SSA’s retail locations.

Data thiefKrebs on Security reports that the attack is widespread. Mr. Krebs cites financial industry sources that say the breach likely involves SSA concession and gift shops at zoo locations in Alabama, Arizona, California, Florida, Hawaii, Idaho, Indiana, Minnesota, Ohio, Oklahoma. Pennsylvania, South Caroline, Texas, and Tennessee.

Systems used at the Detroit Zoo for tickets food sales and membership sales were not affected by the breach and remain secure. Anyone who made a purchase via credit or debit card at a Zoo gift shop should check their bank statements immediately.

Those who expect that their identity has been stolen are asked to contact one of the consumer reporting agencies and place a fraud alert on their credit report.

Why don’t these POS companies give a damn? I have covered POS data breaches a number of times from the Bach Seat. POS breaches have been the largest source of data disclosure for at least 3 years. Of course, we know the answer, follow the money.

FPOS systemirms like SSA have no accountability. There are no costs or fines or even a demerit on their permanent record when they get breached. It is less costly for companies like SSA to allow a breach to happen than it is to update their systems and stop the attackers.

Maybe that will change in the future. Beginning in October 2015 firms like SSA that have not yet installed card readers which accept more secure chip-based cards will assume responsibility for the cost of fraud from counterfeit cards.  – maybe.

The Enemy Within at School

The Enemy Within at SchoolNaked Security reports on a hack that combines two of our favorite things on the Bach Seat, Florida, and lax data security at school. The way the Sophos blog tells the story, a 14-year-old Florida boy is charged with being a hacker by trespassing on his school’s computer system.

Florida school hacker

The charges came after he shoulder-surfed a teacher typing in his password and used it without permission to trespass in the network. The student then tried to embarrass a teacher he doesn’t like by swapping his desktop wallpaper with an image of two men kissing.

an offense against a computer system and unauthorized accessA Tampa Bay Times article says that an eighth-grader was recently arrested for “an offense against a computer system and unauthorized access.” This is a felony in Fla. Sheriff Chris Nocco said that the teen logged onto the network of a Pasco County School District school using an administrative-level password without permission.

A spokesman for the Pasco County Sheriff’s Office told Network World that the student was not detained. Rather, he was questioned at the school before being released to his mother. His sentence remains to be seen, But at this point, it’s looking like the boy isn’t going to suffer much more than a 10-day school suspension. Sheriff’s detective Anthony Bossone says is likely to be “pretrial intervention” by a judge with regards to the felony charge, the Tampa Bay Times reports. Naked Security says this is the student’s second offense.

Old school securityWhen the newspaper interviewed the student, he said that he’s not the only one who uses that password. Other students commonly log into the administrative account to screen-share with their friends, he said. It’s a well-known trick, the student said. He claimed the password was a snap to remember, it’s just the teacher’s last name, which the boy says he learned by watching the teacher type it in.

The sheriff says that the student didn’t just access the teacher’s computer to pull his wallpaper prank. He also reportedly accessed a computer with sensitive data – the state’s standardized tests (now we know why he is in trouble – NCLB! – Common Core!!while logged in as an administrator. Those are files he well could have viewed or tampered with, though he denies having done so. Sheriff Nocco says that’s the reason why this can’t be dismissed as being just a bit of fun. Even though some might say this is just a teenage prank, who knows what this teenager might have done.

I logged out of that computer and logged into a different one and I logged into a teacher’s computer who I didn’t like and tried putting inappropriate pictures onto his computer to annoy him.

in typical HS-er logic, he told the newspaper:

If they’d have notified me it was illegal, I wouldn’t have done it in the first place. But all they said was ‘You shouldn’t be doing that.

Idaho school hacker

rented a cloud based botnet to launch a distributed denial of serviceAnother report from the other side of the continent comes from Engadget. They report that a teenager from Idaho took advantage of the latest trend in online criminal activity. He likely rented a cloud-based botnet to launch a distributed denial of service (DDos) against the largest school district in Idaho. The alleged DDoS took down the school district’s internet access according to media reports.

KTVB News reports that the 17-year-old student paid a third party to conduct a distributed denial-of-service attack/ The attack forced the entire West Ada school district offline. The act disrupted more than 50 schools, bringing everything from payroll to standardized tests (More high stakes testing – NCLB! Common Core!!) grinding to a halt. Unfortunate students undertaking the Idaho Standard Achievement test had to go through the process multiple times because the system kept losing their work and results.

State and Federal felony chargesThe report goes on to say that authorities have found the Eagle High student from their IP address. The students could now face State and Federal felony charges. If found guilty, the unnamed individual is likely to serve up to 180 days in jail, as well as being expelled from school. In addition, the suspect’s parents will be asked to pay for the financial losses suffered as a consequence of the attack.

Many school networks have bigger pipes than the business world. Some EDU networks I have worked on have had 10 GigE for years. In the rest of the online world, these incidents would serve as a wake-up call to network managers that hey, we might be at risk too, but not schools. Oh yeah – Passwords are Evil

Rightly or wrongly schools rely on the Intertubes for their core business – instruction, and NCLB high-stakes testing. However, they do not take steps to protect themselves. Administrators fight common tactics like periodic password changes, enforcing password complexity, or blacklisting common weak passwords. None bother with an anti-DDOS strategy let alone buying a tool to fight off a denial of service attack.

How Social Engineering Works

From where I sit in my Bach Seat, it isHow Social Engineering Works clear that cyber-attackers will try anything to penetrate your online security. They will even exploit human nature to get access to a firm’s digital assets. In the human world, people who exploit human nature are often called politicians, con-men, or grifters. In the digital domain, we call it social engineering. Most online attackers use some sort of social engineering to get users to do something risky.

Social engineering psychological tricks

Here is a list of 6 psychological tricks that social engineers use to trick staff.

1- Reciprocation – When people are provided with something, they tend to feel obligated and then repay the favor.

2 – Scarcity – People tend to comply when they believe something is in short supply. As an example, consider a spoof email claiming to be from a bank asking the user to comply with a request or else have their account disabled within 24 hours.

3 – Consistency –  Once targets have promised to do something, they usually stick to their promises because people do not wish to appear untrustworthy or unreliable. For example, a hacker posing as a company’s IT team could have an employee agree to abide by all security processes, then ask them to do a suspicious task supposedly in line with security requirements.

4 – Liking – Targets are more likely to comply when the social engineer is someone they like. A hacker could use charm via the phone or online to win over an unsuspecting victim.

stick to their promises5 – Authority – People tend to comply when a request comes from a figure of authority. So a targeted email to the finance team that appears to come from the CEO or company president will likely prove effective.

6 – Social validation – People tend to comply when others are doing the same thing. For example, a phishing email might look as if it’s sent to a group of employees, which makes each employee believe the message must be valid if other colleagues also received it.

Conditioned to click

An article at Help Net Security Proofpoint argues that humans are psychologically conditioned (rb- Remember Pavlov’s dogs from Pysch 101?to click on links. Cyber-criminals leverage this conditioning by designing phishing emails most likely to trigger your automatic click response.

Proofpoint says that social engineering emails are so convincing and compelling that they fool 10% of recipients into clicking on the malicious link. To put that into context a legitimate marketing department typically expects a <2% click rate on their advertising campaigns.

Steps to protect against social engineering

They offer the following suggestions to protect against social engineering phishing emails:

  1. Understand that you are not being targeted specifically, you and your machine are just collateral damage.
  2. Upgrade your computer from Windows XP (as Microsoft is no longer providing security updates to the OS) or disconnect it from the internet – it’s that dangerous.
  3. Don’t use simple predictable passwords that are easy to crack.

Businesses need to:

  1. Put in place layered security to provide an in-depth defense against the latest attacks and malware.
  2. Run awareness campaigns with your staff telling them not to click on links within social networking emails such as LinkedIn invitations. They should instead open their browser or app, log in, and manage their invites/messages from there.
  3. Deploy new technologies that combine big data security analytics with advanced malware analysis. These technologies provide predictive and click-time defense, end-to-end attack campaign insight. They also offer automated incident containment capabilities through connectors to your existing security layers.
