Technology and hacking gave a new horizon to the science fiction movies. As hacking is getting common and every online thing is at risk whether it's 10% or 90%, not a system is 100% secure over the internet. Every day new security holes are getting discovered. So, now most of the sci-fi movies have the tech and hack stuff to grow awareness in everybody's mind about the online privacy and risk to their information. Here I am sharing top 10 hacking movies that worth a watch.

TOP 10 HACKING MOVIES

Here I have listed top 10 hacking movies that you should watch.

1. HACKERS (1995)

In Hackers, Angelina Jolie and Jonny Lee Miller portray two youthful and hip hackers. Miller portrays a hacker who got caught as a very young child at an age of 11 years after crashing thousands of computers and has been sentenced to zero computer access until his 18th birthday.

2. LIVE FREE OR DIE HARD (2007)

Live Free or Die Hard (also known as Die Hard 4 and released as Die Hard 4.0 outside North America) is a 2007 American action film, and the fourth in the Die Hard film series depicts a scenario where a hacker played by Timothy Olyphant (of Justified fame) takes down nearly the entire U.S. infrastructure in an attempt to transfer trillions of dollars from the Federal Reserve to his account. This movie gives a complete idea of how actually these blackhat hackers operate.

3. EAGLE EYE (2008)

In this movie, two people get a call from an unknown number by a woman. They get a task on the phone that if they don't follow the phone call they would die. This movie displays supercomputer hack on all networks and military networks. This is just an amazing movie on how artificial intelligence computer hacks our real life for bad motives.

4. ALGORITHM (2014)

The film 'Algorithm' tracks the travails of Will, who is the freelance computer hacker who hacks into a top-secret government contractor agency and downloads all their recently developed programs." You can see the full movie below

5. WARGAMES (1983)

The film features David Lightman (Broderick), a young high school student hacker who accidentally hacks into a military supercomputer and starts the countdown to World War III.

6. THE MATRIX (1999)

This is one of the greatest science fiction movies. In this movie, reality, as perceived by most humans, is actually a simulated reality called "the Matrix", created by machines to subdue the human population, while their bodies' heat and electrical activity are used as an energy source.

A character named "Neo", who is a computer Hacker, learns this truth and is drawn into a rebellion against the machines, which involves other people who have been freed from the "dream world". The Matrix franchise is a trilogy movie series.

7. TAKEDOWN (2000)

This movie is based on famous computer U.S. hacker Kevin David Mitnick. Based upon the book and written by his nemesis, Tsutomu Shimomura, the story tends to glorify Shimomura. Mitnick operated in the 1980s and '90s and eventually went to prison for a couple of years. Now, he is a highly paid IT security consultant, speaker, and writer.

8. BLACKHAT (2015)

Blackhat is newly released movie by Chris Hemsworth. In this movie, hackers hack the Chinese nuclear power plant to start a nuclear reaction. Simultaneously, they also hack the stock exchange and steal millions of dollars from the bank. This movie shows how a black hat hackers threaten governments.

9. THE ITALIAN JOB (2003)

Although the MINI Coopers are really the stars of The Italian Job (a remake of the 1969 film of the same name), Seth Green plays Lyle, a hacker among a group of elite thieves, who is able to manipulate traffic signals, among other devices, that make this grand theft possible.

10. UNTRACEABLE (2008)

This film involves a serial killer who rigs contraptions that kill his victims based on the number of hits received by a website KillWithMe.com that features a live streaming video of the victim. Millions of people log on, hastening the victims' deaths.

There may be more exciting hacking movies but I found these top 10 hacking movies that you should watch for once.

When the Kerberos elevation of privilege (CVE-2014-6324 / MS14-068) vulnerability has been made public, the remediation paragraph of the following blog post made some waves:
http://blogs.technet.com/b/srd/archive/2014/11/18/additional-information-about-cve-2014-6324.aspx

"The only way a domain compromise can be remediated with a high level of certainty is a complete rebuild of the domain."

Personally, I agree with this, but .... But whether this is the real solution, I'm not sure. And the same applies to compromised computers. When it has been identified that malware was able to run on the computer (e.g. scheduled scan found the malware), there is no easy way to determine with 100% certainty that there is no rootkit on the computer. Thus rebuilding the computer might be a good thing to consider. For paranoids, use new hardware ;)

But rebuilding a single workstation and rebuilding a whole domain is not on the same complexity level. Rebuilding a domain can take weeks or months (or years, which will never happen, as the business will close before that).

There are countless documented methods to backdoor a computer, but I have never seen a post where someone collects all the methods to backdoor a domain. In the following, I will refer to domain admin, but in reality, I mean Domain Admins, Enterprise Admins, and Schema Admins.

Ways to backdoor a domain

So here you go, an incomplete list to backdoor a domain:

Create a new domain admin user. Easy to do, easy to detect, easy to remediate
Dump password hashes. The attacker can either crack those or just pass-the-hash. Since KB2871997, pass-the-hash might be trickier (https://technet.microsoft.com/library/security/2871997), but not impossible. Easy to do, hard to detect, hard to remediate - just think about service user passwords. And during remediation, consider all passwords compromised, even strong ones.
Logon scripts - modify the logon scripts and add something malicious in it. Almost anything detailed in this post can be added :D
Use an already available account, and add domain admin privileges to that. Reset its password. Mess with current group memberships - e.g. http://www.exploit-db.com/papers/17167/
Backdoor any workstation where domain admins login. While remediating workstations, don't forget to clean the roaming profile. The type of backdoor can use different forms: malware, local admin, password (hidden admin with 500 RID), sticky keys, etc.
Backdoor any domain controller server. For advanced attacks, see Skeleton keys
Backdoor files on network shares which are commonly used by domain admins by adding malware to commonly used executables - Backdoor factory
Change ownership/permissions on AD partitions - if you have particular details on how to do this specifically, please comment
Create a new domain user. Hide admin privileges with SID history. Easy to do, hard to detect, easy to remediate - check Mimikatz experimental for addsid
Golden tickets - easy to do, hard to detect, medium remediation
Silver tickets - easy to do, hard to detect, medium/hard remediation
Backdoor workstations/servers via group policy

HKEY_LOCAL_MACHINE\ Software\ Microsoft\ Windows\ CurrentVersion\ RunOnce,
scheduled tasks (run task 2 years later),
sticky-keys with debug

Backdoor patch management tool, see slides here

[Update 2017.01.10]

Other tricks

The following list does not fit in the previous "instant admin" tips, but still, it can make the attackers life easier if their primary foothold has been disabled:

Backdoor recent backups - and when the backdoor is needed, destroy the files, so the files will be restored from the backdoored backup
Backdoor the Exchange server - get a copy of emails
Backdoor workstation/server golden image
Change permission of logon scripts to allow modification later
Place malicious symlinks to file shares, collect hashes via SMB auth tries on specified IP address, grab password hashes later
Backdoor remote admin management e.g. HP iLO - e.g. create new user or steal current password
Backdoor files e.g. on shares to use in SMB relay
Backdoor source code of in-house-developed software
Use any type of sniffed or reused passwords in new attacks, e.g. network admin, firewall admin, VPN admin, AV admin, etc.
Change the content of the proxy pac file (change browser configuration if necessary), including special exception(s) for a chosen domain(s) to use proxy on malicious IP. Redirect the traffic, enforce authentication, grab password hashes, ???, profit.
Create high privileged users in applications running with high privileges, e.g. MSSQL, Tomcat, and own the machine, impersonate users, grab their credentials, etc. The typical pentest path made easy.
Remove patches from servers, change patch policy not to install those patches.
Steal Windows root/intermediate CA keys
Weaken AD security by changing group policy (e.g. re-enabling LM-hashes)

Update [2015-09-27]: I found this great presentation from Jakob Heidelberg. It mentions (at least) the following techniques, it is worth to check these:

Microsoft Local Administrator Password Solution
Enroll virtual smart card certificates for domain admins

Forensics

If you have been chosen to remediate a network where attackers gained domain admin privileges, well, you have a lot of things to look for :)

I can recommend two tools which can help you during your investigation:

Lessons learned

But guess what, not all of these problems are solved by rebuilding the AD. One has to rebuild all the computers from scratch as well. Which seems quite impossible. When someone is creating a new AD, it is impossible not to migrate some configuration/data/files from the old domain. And whenever this happens, there is a risk that the new AD will be backdoored as well.

Ok, we are doomed, but what can we do? I recommend proper log analysis, analyze trends, and detect strange patterns in your network. Better spend money on these, than on the domain rebuild. And when you find something, do a proper incident response. And good luck!

Ps: Thanks to Andrew, EQ, and Tileo for adding new ideas to this post.
