Symantec Reports on Cicada APT Attacks against Japan

Symantec is reporting on an APT group linked to China, named Cicada. They have been attacking organizations in Japan and elsewhere.

Cicada has historically been known to target Japan-linked organizations, and has also targeted MSPs in the past. The group is using living-off-the-land tools as well as custom malware in this attack campaign, including a custom malware — Backdoor.Hartip — that Symantec has not seen being used by the group before. Among the machines compromised during this attack campaign were domain controllers and file servers, and there was evidence of files being exfiltrated from some of the compromised machines.

The attackers extensively use DLL side-loading in this campaign, and were also seen leveraging the ZeroLogon vulnerability that was patched in August 2020.

Interesting details about the group’s tactics.

NSA Advisory on Chinese Government Hacking

The NSA released an advisory listing the top twenty-five known vulnerabilities currently being exploited by Chinese nation-state attackers.

This advisory provides Common Vulnerabilities and Exposures (CVEs) known to be recently leveraged, or scanned-for, by Chinese state-sponsored cyber actors to enable successful hacking operations against a multitude of victim networks. Most of the vulnerabilities listed below can be exploited to gain initial access to victim networks using products that are directly accessible from the Internet and act as gateways to internal networks. The majority of the products are either for remote access (T1133) or for external web services (T1190), and should be prioritized for immediate patching.

Chinese COVID-19 Disinformation Campaign

The New York Times is reporting on state-sponsored disinformation campaigns coming out of China:

Since that wave of panic, United States intelligence agencies have assessed that Chinese operatives helped push the messages across platforms, according to six American officials, who spoke on the condition of anonymity to publicly discuss intelligence matters. The amplification techniques are alarming to officials because the disinformation showed up as texts on many Americans’ cellphones, a tactic that several of the officials said they had not seen before.

Facial Recognition for People Wearing Masks

The Chinese facial recognition company Hanwang claims it can recognize people wearing masks:

The company now says its masked facial recognition program has reached 95 percent accuracy in lab tests, and even claims that it is more accurate in real life, where its cameras take multiple photos of a person if the first attempt to identify them fails.


Counter-intuitively, training facial recognition algorithms to recognize masked faces involves throwing data away. A team at the University of Bradford published a study last year showing they could train a facial recognition program to accurately recognize half-faces by deleting parts of the photos they used to train the software.

When a facial recognition program tries to recognize a person, it takes a photo of the person to be identified, and reduces it down to a bundle, or vector, of numbers that describes the relative positions of features on the face.


Hanwang’s system works for masked faces by trying to guess what all the faces in its existing database of photographs would look like if they were masked.

Emergency Surveillance During COVID-19 Crisis

Israel is using emergency surveillance powers to track people who may have COVID-19, joining China and Iran in using mass surveillance in this way. I believe pressure will increase to leverage existing corporate surveillance infrastructure for these purposes in the US and other countries. With that in mind, the EFF has some good thinking on how to balance public safety with civil liberties:

Thus, any data collection and digital monitoring of potential carriers of COVID-19 should take into consideration and commit to these principles:

  • Privacy intrusions must be necessary and proportionate. A program that collects, en masse, identifiable information about people must be scientifically justified and deemed necessary by public health experts for the purpose of containment. And that data processing must be proportionate to the need. For example, maintenance of 10 years of travel history of all people would not be proportionate to the need to contain a disease like COVID-19, which has a two-week incubation period.
  • Data collection based on science, not bias. Given the global scope of communicable diseases, there is historical precedent for improper government containment efforts driven by bias based on nationality, ethnicity, religion, and race­ — rather than facts about a particular individual’s actual likelihood of contracting the virus, such as their travel history or contact with potentially infected people. Today, we must ensure that any automated data systems used to contain COVID-19 do not erroneously identify members of specific demographic groups as particularly susceptible to infection.
  • Expiration. As in other major emergencies in the past, there is a hazard that the data surveillance infrastructure we build to contain COVID-19 may long outlive the crisis it was intended to address. The government and its corporate cooperators must roll back any invasive programs created in the name of public health after crisis has been contained.
  • Transparency. Any government use of “big data” to track virus spread must be clearly and quickly explained to the public. This includes publication of detailed information about the information being gathered, the retention period for the information, the tools used to process that information, the ways these tools guide public health decisions, and whether these tools have had any positive or negative outcomes.
  • Due Process. If the government seeks to limit a person’s rights based on this “big data” surveillance (for example, to quarantine them based on the system’s conclusions about their relationships or travel), then the person must have the opportunity to timely and fairly challenge these conclusions and limits.

US Department of Interior Grounding All Drones

The Department of Interior is grounding all non-emergency drones due to security concerns:

The order comes amid a spate of warnings and bans at multiple government agencies, including the Department of Defense, about possible vulnerabilities in Chinese-made drone systems that could be allowing Beijing to conduct espionage. The Army banned the use of Chinese-made DJI drones three years ago following warnings from the Navy about “highly vulnerable” drone systems.

One memo drafted by the Navy & Marine Corps Small Tactical Unmanned Aircraft Systems Program Manager has warned “images, video and flight records could be uploaded to unsecured servers in other countries via live streaming.” The Navy has also warned adversaries may view video and metadata from drone systems even though the air vehicle is encrypted. The Department of Homeland Security previously warned the private sector their data may be pilfered off if they use commercial drone systems made in China.

I’m actually not that worried about this risk. Data moving across the Internet is obvious — it’s too easy for a country that tries this to get caught. I am much more worried about remote kill switches in the equipment.

Chinese Hackers Bypassing Two-Factor Authentication

Interesting story of how a Chinese state-sponsored hacking group is bypassing the RSA SecurID two-factor authentication system.

How they did it remains unclear; although, the Fox-IT team has their theory. They said APT20 stole an RSA SecurID software token from a hacked system, which the Chinese actor then used on its computers to generate valid one-time codes and bypass 2FA at will.

Normally, this wouldn’t be possible. To use one of these software tokens, the user would need to connect a physical (hardware) device to their computer. The device and the software token would then generate a valid 2FA code. If the device was missing, the RSA SecureID software would generate an error.

The Fox-IT team explains how hackers might have gone around this issue:

The software token is generated for a specific system, but of course this system specific value could easily be retrieved by the actor when having access to the system of the victim.

As it turns out, the actor does not actually need to go through the trouble of obtaining the victim’s system specific value, because this specific value is only checked when importing the SecurID Token Seed, and has no relation to the seed used to generate actual 2-factor tokens. This means the actor can actually simply patch the check which verifies if the imported soft token was generated for this system, and does not need to bother with stealing the system specific value at all.

In short, all the actor has to do to make use of the 2 factor authentication codes is to steal an RSA SecurID Software Token and to patch 1 instruction, which results in the generation of valid tokens.

GPS Manipulation

Long article on the manipulation of GPS in Shanghai. It seems not to be some Chinese military program, but ships who are stealing sand.

The Shanghai “crop circles,” which somehow spoof each vessel to a different false location, are something new. “I’m still puzzled by this,” says Humphreys. “I can’t get it to work out in the math. It’s an interesting mystery.” It’s also a mystery that raises the possibility of potentially deadly accidents.

“Captains and pilots have become very dependent on GPS, because it has been historically very reliable,” says Humphreys. “If it claims to be working, they rely on it and don’t double-check it all that much.”

On June 5 this year, the Run 5678, a river cargo ship, tried to overtake a smaller craft on the Huangpu, about five miles south of the Bund. The Run avoided the small ship but plowed right into the New Glory (Chinese name: Tong Yang Jingrui), a freighter heading north.
