New York Increases Cybersecurity Rules for Financial Companies

Another example of a large and influential state doing things the federal government won’t:

Boards of directors, or other senior committees, are charged with overseeing cybersecurity risk management, and must retain an appropriate level of expertise to understand cyber issues, the rules say. Directors must sign off on cybersecurity programs, and ensure that any security program has “sufficient resources” to function.

In a new addition, companies now face significant requirements related to ransom payments. Regulated firms must now report any payment made to hackers within 24 hours of that payment…

Ethical Problems in Computer Security

Tadayoshi Kohno, Yasemin Acar, and Wulf Loh wrote excellent paper on ethical thinking within the computer security community: “Ethical Frameworks and Computer Security Trolley Problems: Foundations for Conversation“:

Abstract: The computer security research community regularly tackles ethical questions. The field of ethics / moral philosophy has for centuries considered what it means to be “morally good” or at least “morally allowed / acceptable.” Among philosophy’s contributions are (1) frameworks for evaluating the morality of actions—including the well-established consequentialist and deontological frameworks—and (2) scenarios (like trolley problems) featuring moral dilemmas that can facilitate discussion about and intellectual inquiry into different perspectives on moral reasoning and decision-making. In a classic trolley problem, consequentialist and deontological analyses may render different opinions. In this research, we explicitly make and explore connections between moral questions in computer security research and ethics / moral philosophy through the creation and analysis of trolley problem-like computer security-themed moral dilemmas and, in doing so, we seek to contribute to conversations among security researchers about the morality of security research-related decisions. We explicitly do not seek to define what is morally right or wrong, nor do we argue for one framework over another. Indeed, the consequentialist and deontological frameworks that we center, in addition to coming to different conclusions for our scenarios, have significant limitations. Instead, by offering our scenarios and by comparing two different approaches to ethics, we strive to contribute to how the computer security research field considers and converses about ethical questions, especially when there are different perspectives on what is morally right or acceptable. Our vision is for this work to be broadly useful to the computer security community, including to researchers as they embark on (or choose not to embark on), conduct, and write about their research, to program committees as they evaluate submissions, and to educators as they teach about computer security and ethics…

Computer Repair Technicians Are Stealing Your Data

Laptop technicians routinely violate the privacy of the people whose computers they repair:

Researchers at University of Guelph in Ontario, Canada, recovered logs from laptops after receiving overnight repairs from 12 commercial shops. The logs showed that technicians from six of the locations had accessed personal data and that two of those shops also copied data onto a personal device. Devices belonging to females were more likely to be snooped on, and that snooping tended to seek more sensitive data, including both sexually revealing and non-sexual pictures, documents, and financial information…

Recovering Passwords by Measuring Residual Heat

Researchers have used thermal cameras and ML guessing techniques to recover passwords from measuring the residual heat left by fingers on keyboards. From the abstract:

We detail the implementation of ThermoSecure and make a dataset of 1,500 thermal images of keyboards with heat traces resulting from input publicly available. Our first study shows that ThermoSecure successfully attacks 6-symbol, 8-symbol, 12-symbol, and 16-symbol passwords with an average accuracy of 92%, 80%, 71%, and 55% respectively, and even higher accuracy when thermal images are taken within 30 seconds. We found that typing behavior significantly impacts vulnerability to thermal attacks, where hunt-and-peck typists are more vulnerable than fast typists (92% vs 83% thermal attack success if performed within 30 seconds). The second study showed that the keycaps material has a statistically significant effect on the effectiveness of thermal attacks: ABS keycaps retain the thermal trace of users presses for a longer period of time, making them more vulnerable to thermal attacks, with a 52% average attack accuracy compared to 14% for keyboards with PBT keycaps…

Bypassing Two-Factor Authentication

These techniques are not new, but they’re increasingly popular:

…some forms of MFA are stronger than others, and recent events show that these weaker forms aren’t much of a hurdle for some hackers to clear. In the past few months, suspected script kiddies like the Lapsus$ data extortion gang and elite Russian-state threat actors (like Cozy Bear, the group behind the SolarWinds hack) have both successfully defeated the protection.

[…]

Methods include:

  • Sending a bunch of MFA requests and hoping the target finally accepts one to make the noise stop.
