Anatomy of a Targeted Attack Attackers Move Methodically to GainPersistent & Ongoing Access to Their Targets • Net use commands • Reverse shell access • Backdoor variants • VPN subversion • Sleeper malware MaintainPresence MoveLaterally Initial Compromise Establish Foothold Escalate Privileges Internal Recon Complete Mission • Custom malware • Command and control • 3rd party application exploitation • Credential theft • Password cracking • “Pass-the-hash” • Critical system recon • System, active directory & user enumeration • Staging servers • Data consolidation • Data theft • Social engineering • Spear phishing e-mail with custom malware At organizations where Mandiant responded to a targeted attack in the last year, the typical attacker went undetected for 273 days.
Visibility is critical MaintainPresence MoveLaterally Initial Compromise Establish Foothold Escalate Privileges Internal Recon Complete Mission Unauthorized Use of Valid Accounts Known & Unknown Malware Command & Control Activity Suspicious Network Traffic Files Accessed by Attackers Valid Programs Used for Evil Purposes Trace Evidence & Partial Files EVIDENCE OF COMPROMISE Of all of the compromised machines Mandiantidentified in 2011, only 54% had malware on them.
Background • Monday, February 18, 2013 Mandiant released intelligence report on threat group: APT1 • Linked APT1 to PLA unit 61398 • Provided hard evidence • Released 3000+ immediately actionable indicators of compromise • OpenIOC format • Malware reports • IPs/domain names • MD5s • SSL Certificates • 5 minute video showing footage of the attacker in action • Set the bar for actionable intelligence sharing
The People • ~30 core people worked on actual report • Threat Intelligence • IOCs • M-Labs • Marketing, legal, execs… • Significant effort to validate and consolidate data (and conduct open source research) under tight deadline • Though the “surge” was intense, it was made possible by 7 years of previous research
Why? • Prolific • Volume of data stolen • Comprehensive understanding of tools, tactics, and procedures • Example of actionable information sharing • The timing felt right • Traffic Light Protocol (TLP): Green indicator disclosure • Not as intel-sensitive as other groups
Criticisms • We’ve received lots of it! • Why do you always pick on China?! • Focusing on the country of origin is the wrong issue • Don’t focus on the attacker, focus on your defenses • Mandiant disclosed sensitive intel and ruined intelligence operations • Publicity stunt
Accuracy • CNN video shows military chasing CNN vehicle near the building while filming https://www.youtube.com/watch?v=yG2ezzLHSD0 • Sen. Feinstein, Chairman Senate Intelligence Committee: • “I read the Mandiant report. I've also read other reports, classified out of Intelligence, and I think the Mandiant report, which is now unclassified, it's public, is essentially correct,” http://thehill.com/blogs/global-affairs/terrorism/284721-intel-chairwoman-report-on-chinas-cyber-war-unit-essentially-correct
Accuracy – Netizen Research • DOTA phone number discovered used in 2009 for apartment rental – 600 feet from unit 61398. • SuperHard_M (aka Mei Qiang) likely studied at famous PLA Information Engineering University in 2005. • 2004 recruitment notice on Zhejiang University website advertising for “Unit 61398 of China’s PLA (located in Pudong District, Shanghai) seeks to recruit 2003-class computer science graduate students.” • LA Times found blog of possible 61398 worker: http://lat.ms/12OATUY https://www.mandiant.com/blog/netizen-research-bolsters-apt1-attribution
APT1 – Reaction after a week • Monday 2/18 – Business as usual • Report is released at 10 PM EST – 11 AM CST • Tuesday 2/19 – Clear signs of action plan being invoked • Domains getting parked • WHOIS registry getting changed • Backdoor/tools removed • Staging/working directories cleared • New backdoors implanted (leverage public communications channels – hotmail/gmail/MSN) • MACROMAIL malware from APT1 report • Today: many indicators changed, but otherwise business as usual
APT1 vs. APT12 • NY Times disclosed internal name APT12 • Tools: • APT1 – WEBC2, public communication channels, noisy • APT12 – DNS calc, cmdline backdoors, more stealthy • Data theft: • APT1 – everything • APT12 - discriminating • Skill: • APT1 – good enough, large range of skillsets • APT12 – more skilled • Industries targeted: • APT1 – everything • APT12 – satellite, crypto, media
Trend #1 – Outside In • When targeted organizations increase their prevention and detection capability, weaker service providers and partners become targets • Mandiant investigated several organizations that had been compromised through 3rd party connections • 15% of victims in 2012 were notified by a service provider
Trend #2 – ‘X’ Marks the Spot • Attacks are becoming more surgical in nature: immediately targeting administrators for network diagrams, sensitive asset lists • Change from historical reliance on internal network reconnaissance • One victim had followed all the necessary precautions to protect their financial information, yet attacks against system administrators yielded necessary data to breach the environment
Trend #3 – Once a Target, Always a Target • Though long known anecdotally, Mandiant measured repeat victimization in 2012 • 38% of victims were re-compromised within the year • Reminder that persistence means constant attempts at re-compromise until mission is accomplished
Trend #4 – Strategic Web Compromise • Mandiant observed frequent use of strategic web compromises, or “watering hole attacks” over the last year • Financial institutions attacked via Java exploits on local news web sites • Energy companies compromised through an industry portal • Significant collateral damage
