Firing Back with Vengeance: the NSA Weapons

from you tube.

The strike on IDT, a conglomerate,… was similar to WannaCry in one way: Hackers locked up IDT data and demanded a ransom to unlock it.  But the ransom demand was just a smoke screen for a far more invasive attack that stole employee credentials. With those credentials in hand, hackers could have run free through the company’s computer network, taking confidential information or destroying machines….Were it not for a digital black box that recorded everything on IDT’s network, …the attack might have gone unnoticed.

Scans for the two hacking tools used against IDT indicate that the company is not alone. In fact, tens of thousands of computer systems all over the world have been “backdoored” by the same N.S.A. weapons. Mr. Ben-Oni and other security researchers worry that many of those other infected computers are connected to transportation networks, hospitals, water treatment plants and other utilities…

Both WannaCry and the IDT attack used a hacking tool the agency had code-named EternalBlue. The tool took advantage of unpatched Microsoft servers to automatically spread malware from one server to another, so that within 24 hours… hackers had spread their ransomware to more than 200,000 servers around the globe. The attack on IDT went a step further with another stolen N.S.A. cyberweapon, called DoublePulsar. The N.S.A. used DoublePulsar to penetrate computer systems without tripping security alarms. It allowed N.S.A. spies to inject their tools into the nerve center of a target’s computer system, called the kernel, which manages communications between a computer’s hardware and its software.

In the pecking order of a computer system, the kernel is at the very top, allowing anyone with secret access to it to take full control of a machine. It is also a dangerous blind spot for most security software, allowing attackers to do what they want and go unnoticed. In IDT’s case, attackers used DoublePulsar to steal an IDT contractor’s credentials. Then they deployed ransomware in what appears to be a cover for their real motive: broader access to IDT’s businesses…

But the attack struck Mr. Ben-Oni as unique. For one thing, it was timed perfectly to the Sabbath. Attackers entered IDT’s network at 6 p.m. on Saturday on the dot, two and a half hours before the Sabbath would end and when most of IDT’s employees — 40 percent of whom identify as Orthodox Jews — would be off the clock. For another, the attackers compromised the contractor’s computer through her home modem — strange.

The black box of sorts, a network recording device made by the Israeli security company Secdo, shows that the ransomware was installed after the attackers had made off with the contractor’s credentials. And they managed to bypass every major security detection mechanism along the way. Finally, before they left, they encrypted her computer with ransomware, demanding $130 to unlock it, to cover up the more invasive attack on her computer.

A month earlier, Microsoft had issued a software patch to defend against the N.S.A. hacking tools — suggesting that the agency tipped the company off to what was coming. Microsoft regularly credits those who point out vulnerabilities in its products, but in this case the company made no mention of the tipster. Later, when the WannaCry attack hit hundreds of thousands of Microsoft customers, Microsoft’s president, Brad Smith, slammed the government in a blog post for hoarding and stockpiling security vulnerabilities.  For his part, Mr. Ben-Oni said he had rolled out Microsoft’s patches as soon as they became available, but attackers still managed to get in through the IDT contractor’s home modem.

There are now YouTube videos showing criminals how to attack systems using the very same N.S.A. tools used against IDT, and Metasploit, an automated hacking tool, now allows anyone to carry out these attacks with the click of a button….

“Once DoublePulsar is on the machine, there’s nothing stopping anyone else from coming along and using the back door,” Mr. Dillon said.More distressing, Mr. Dillon tested all the major antivirus products against the DoublePulsar infection and a demoralizing 99 percent failed to detect it.  “We’ve seen the same computers infected with DoublePulsar for two months and there is no telling how much malware is on those systems,” Mr. Dillon said. “Right now we have no idea what’s gotten into these organizations.”..

Could that attack be coming? The Shadow Brokers resurfaced last month, promising a fresh load of N.S.A. attack tools, even offering to supply them for monthly paying subscribers — like a wine-of-the-month club for cyberweapon enthusiasts.

Needles and Haystack and Beyond: DARPA

From DARPA pdf document available at  FedBizOpps. Gov Enhanced Attribution
Solicitation Number: DARPA-BAA-16-34

Malicious actors in cyberspace currently operate with little fear of being caught due to the fact that it is extremely difficult, in some cases perhaps even impossible, to reliably and confidently attribute actions in cyberspace to individuals. The reason cyber attribution is difficult stems at least in part from a lack of end-to-end accountability in the current Internet infrastructure…..The identities of malicious cyber operators are largely obstructed by the use of multiple layers of indirection… The lack of detailed information about the actions and identities of the adversary cyber operators inhibits policymaker considerations and decisions for both cyber and non-cyber response options (e.g., economic sanctions under EO-13694).

The DARPA’s Enhanced Attribution program aims to make currently opaque malicious cyber adversary actions and individual cyber operator attribution transparent by providing high-fidelity visibility into all aspects of malicious cyber operator actions and to increase the Government’s ability to publicly reveal the actions of individual malicious cyber operators without damaging sources and methods….

The program seeks to develop:

–technologies to extract behavioral and physical biometrics from a range of devices and
vantage points to consistently identify virtual personas and individual malicious cyber
operators over time and across different endpoint devices and C2 infrastructures;
–techniques to decompose the software tools and actions of malicious cyber operators into
semantically rich and compressed knowledge representations;
–scalable techniques to fuse, manage, and project such ground-truth information over time,
toward developing a full historical and current picture of malicious activity;–algorithms for developing predictive behavioral profiles within the context of cyber campaigns; and
–technologies for validating and perhaps enriching this knowledge base with other sources
of data, including public and commercial sources of information.

How to Tear Down a Power Grid

pylons. image from wikipedia

In Ukraine on Dec. 23, 2015 the power suddenly went out for thousands of people in the capital, Kiev, and western parts of the country. While technicians struggled for several hours to turn the lights back on, frustrated customers got nothing but busy signals at their utilities’ call centers….Hackers had taken down almost a quarter of the country’s power grid, claimed Ukrainian officials.  Specifically, the officials blamed Russians for tampering with the utilities’ software, then jamming the power companies’ phone lines to keep customers from alerting anyone….Several of the firms researching the attack say signs point to Russians as the culprits. The malware found in the Ukrainian grid’s computers, BlackEnergy3, is a known weapon of only one hacking group—dubbed Sandworm by researcher ISight Partners—whose attacks closely align with the interests of the Russian government. The group carried out attacks against the Ukrainian government and NATO in 2014…

The more automated U.S. and European power grids are much tougher targets. To cloak Manhattan in darkness, hackers would likely need to discover flaws in the systems the utilities themselves don’t know exist before they could exploit them. In the Ukrainian attack, leading security experts believe the hackers simply located the grid controls and delivered a command that shut the power off. Older systems may be more vulnerable to such attacks, as modern industrial control software is better at recognizing and rejecting unauthorized commands, says IOActive’s Larsen.

That said, a successful hack of more advanced U.S. or European systems would be a lot harder to fix. Ukrainian utility workers restored power by rushing to each disabled substation and resetting circuit breakers manually. Hackers capable of scrambling New York’s power plant software would probably have to bypass safety mechanisms to run a generator or transformer hotter than normal, physically damaging the equipment. That could keep a substation offline for days or weeks, says Michael Assante, former chief security officer for the nonprofit North American Electric Reliability.

Hackers may have targeted Ukraine’s grid for the same reason NATO jets bombed Serbian power plants in 1999: to show the citizenry that its government was too weak to keep the lights on. The hackers may even have seen the attack as in-kind retaliation after sabotage left 1.2 million people in Kremlin-controlled Crimea without lights in November 2015. In that case, saboteurs blew up pylons with explosives, then attacked the repair crews that came to fix them, creating a blackout that lasted for days. Researchers will continue to study the cyber attack in Ukraine, but the lesson may be that when it comes to war, a bomb still beats a keyboard.

How to Forecast a Cyber Atttack: IARPA cyber intelligence

DDoS Stachledraht attack. Image from wikipedia

From the website of IARPA (Intelligence Advanced Research Projects Activity (IARPA) — a US research agency under the Director of National Intelligence.

“Approaches to cyber defense typically focus on post-mortem analysis of the various attack vectors utilized by adversaries. As attacks have evolved and increased over the years, established approaches (e.g., signature-based detection, anomaly detection) have not adequately enabled cybersecurity practitioners to get ahead of these threats. This has led to an industry that has invested heavily in analyzing the effects of cyber-attacks instead of analyzing and mitigating the “cause” of cyber-attacks,

The CAUSE   (Cyber-attack Automated Unconventional Sensor Environment)Program seeks to develop cyber-attack forecasting methods and detect emerging cyber phenomena to assist cyber defenders with the earliest detection of a cyber-attack (e.g., Distributed Denial of Service (DDoS), successful spearphishing, successful drive-by, remote exploitation, unauthorized access, reconnaissance). The CAUSE Program aims to develop and validate unconventional multi-disciplined sensor technology (e.g., actor behavior models, black market sales) that will forecast cyber-attacks and complement existing advanced intrusion detection capabilities. Anticipated innovations include: methods to manage and extract huge amounts of streaming and batch data, the application and introduction of new and existing features from other disciplines to the cyber domain, and the development of models to generate probabilistic warnings for future cyber events. Successful proposers will combine cutting-edge research with the ability to develop robust forecasting capabilities from multiple sensors not typically used in the cyber domain…”

Who Controls the Computers in North Korea–the Wapomi worm

Trojan. image from wikipedia

Foreign hackers could have broken into North Korean computers and used them to make the country look responsible for hacking Sony, experts have said.  Any attempt to blame North Korea for the attack because hackers used a North Korean IP address “must be treated as suspect”, security firm Cloudmark said. That is one of the reasons that the FBI has given for suspecting the country for the attack, which took down Sony Pictures’ systems for weeks.  Security experts have continued to be dubious of the claim, but FBI officials have continued to blame North Korea.

The country has a very small connection to the internet, run by its national telecom ministry and a Thai firm. As a demonstration of how few connections North Korea has to the internet, Cloudmark said that it has the same amount of IP addresses allocated to it as the entire country.  Cloudmark said that the North Korean addresses it traces tend to send out spam, which is usually the sign of an infected machine. It identified the Wapomi worm, which is transmitted by USB drives and file server shares, as the code that is allowing outside people to control the machine.

While there is no guarantee that the same worm is present on the computers that have carried out the attack, the prevalence of infected computers in the country shows how easy it could have been for Sony’s hackers to give the impression they were based on North Korea.  Cloud mark said that “unless the FBI releases more specific details of their case against North Korea, including email headers and mail server logs, some experts will continue to question if they are in fact correct”.

CyberWeapons: the Regin Malware

Malware Statistics

An advanced piece of malware, newly uncovered, has been in use since as early as 2008 to spy on governments, companies and individuals, Symantec said in a report .  The Regin cyberespionage tool uses several stealth features to avoid detection, a characteristic that required a significant investment of time and resources and that suggests it’s the product of a nation-state, Symantec warned, without hazarding a guess about which country might be behind it. The malware’s design makes it highly suited for long-term mass surveillance, according to the maker of antivirus software…

The highly customizable nature of Regin, which Symantec labeled a “top-tier espionage tool,” allows for a wide range of remote access Trojan capabilities, including password and data theft, hijacking the mouse’s point-and-click functions, and capturing screenshots from infected computers. Other infections were identified monitoring network traffic and analyzing email from Exchange databases….

The malware’s targets are geographically diverse, Symantec said, observing more than half of the infections in Russia and Saudi Arabia. Among the other countries targeted are Ireland, Mexico and India. [ Regin have been identified also in Afghanistan, Algeria, Belgium, Brazil, Fiji, Germany,Indonesia, Iran, Kiribati, Malaysia, Pakistan, Syria]

Regin is composed of five attack stages that are hidden and encrypted, with the exception of the first stage, which begins a domino chain of decrypting and executing the next stage. Each individual stage contains little information about malware’s structure. All five stages had to be acquired to analyze the threat posed by the malware.  The multistage architecture of Regin, Symantec said, is reminiscent of Stuxnet, a sophisticated computer virus discovered attacking a nuclear enrichment facility in Iran in 2010, and Duqu, which has identical code to Stuxnet but which appeared designed for cyber espionage instead of sabotage.  Symantec said it believes that many components of Regin remain undiscovered and that additional functionality and versions may exist.  “Regin uses a modular approach,” Symantec said, “giving flexibility to the threat operators as they can load custom features tailored to individual targets when required.”

Cyberwarriors: US and China

cyberhacking

On May 19th, 2014 the Justice Department unveiled 31 charges against five members of China’s People’s Liberation Army (PLA), involving breaking six laws, from relatively minor counts of identity theft to economic espionage, which carries a maximum sentence of 15 years. This is the first time the government has charged employees of a foreign government with cybercrime. The accused are unlikely ever to stand trial. Even so, the Justice Department produced posters with mugshots of the men beneath the legend “wanted by the FBI”. They may never be punished, but that is not the point. Google any of their names and the mugshots now appear, the online equivalent of a perp walk.

That China’s government spies on the commercial activities of companies in America is not news in itself. Last year Mandiant, a cyber-security firm based in Virginia, released a report that identified Unit 61398 of the PLA as the source of cyber-attacks against 140 companies since 2006. But the indictment does reveal more details about what sorts of things the Chinese cybersnoops have been snaffling.

Hackers stole designs for pipes from Westinghouse, an American firm, when it was building four nuclear power stations in China, and also took e-mails from executives who were negotiating with a state-owned company. They took financial information from SolarWorld, a maker of solar panels; gained access to computers owned by US Steel while it was in a trade dispute with a state-owned company; and took files from Alcoa, an aluminium producer, while it was in a joint venture with another Chinese government-backed firm. ATI, another metal firm, and the United Steelworkers union were hacked, too.

American firms that do business in China have long lobbied behind closed doors for Uncle Sam to do something about Chinese hackers. America’s government has hitherto followed a similar logic, pressing China in private. The decision to make a fuss reflects the failure of that approach. When the existence of Unit 61398 became public its troops paused for a while, then continued as before.

Confronting the PLA’s hackers comes at a cost. China has pulled out of a bilateral working group on cyber-security in response to the indictments. Global Times, a Chinese English-language daily, denounced America as: “a mincing rascal”. But doing nothing has a cost, too. Companies like Westinghouse and US Steel have a hard enough time competing with Chinese firms, without having their business plans and designs pinched by thieves in uniform. Nor is the spying limited to manufacturers: tech companies have been targeted by the same group…

Second, America’s spying on Huawei, a Chinese maker of telecoms and networking equipment, makes China’s government doubt that America follows its own rules.
