All my personal details for chocolate? Go on then

On social engineering, rootkits and Easter eggs


Infosec blog When I explain what I do to Spanish friends and neighbours in my faltering Castilian, people often ask me about malicious hackers. It's very often hard to explain that the viruses they receive in their email are most likely random attacks. A PC is, after all, very personal so it's easy to symphatise with people who take cyber-attacks personally themselves.

But although people reckon hackers are prepared to go to elaborate means to obtain information from their systems (a real risk but one that's sometimes overstated), many are relaxed about handing over sensitive data when approached by someone carrying a clip-board. A survey ahead of next week's Infosecurity Europe show found that 81 per cent of people quizzed at London's Victoria station were willing to part with all the personal information needed to steal their identity for the chance to win an Easter egg bonanza, worth £60.

Seemingly innocuous questions such as about a person's Easter egg consumption and pet collection were inserted into the conversation alongside other queries designed to elicit sensitive information such as a person's date of birth, address and mother's maiden name. The survey, akin to similar studies over recent years, was designed to raise awareness about how easy it is for fraudsters to use social engineering to carry out identity theft. Last year, 92 per cent of people gave over their personal details in a similar survey that offered the lure of theatre tickets as a prize. So perhaps there's been some progress, though forgive me for not being especially impressed.

Security is a consumer issue. True

Security, make no mistake about it, has become a consumer issue. But it's sometimes hard to identify the real risks from the hype that surrounds the industry.

One all too real risk is easy to identify, the possibility that cybercriminals might get their hands on a consumer's credit card details. The credit card details of an estimated 400 Britons are traded online every day, The Times reports. Details complete with security code numbers trade for $5 a pop in underground chat rooms. Valid PIN codes corresponding to these numbers can increase the asking price to $175 (£100) a throw.

Hackers might have employed a variety of techniques to obtain this data. Breaking into a corporate server where credit card information was held (the favoured theory at The Times), going through receipts carelessly discarded at gas stations or social engineering techniques are three possibilities. Infecting a user's PC with keystroke logging software is another strong possibility.

Stealth

A few years ago, systems infected by malicious code would display obvious signs of infection, such as slowing to a crawl or thrashed document files. These days hackers are getting more sneaky. A survey by security firm McAfee published on Monday reports that the use by hackers of stealth technology to disguise the presence of malware on infected systems is up 600 per cent over the last three years.

It reckons this seven-fold increase is largely down to the success of online collaborative research efforts by hackers using Web sites that contain hundreds of lines of rootkit code. "The 'open-source' environment, along with online collaboration sites and blogs are largely to blame for the increased proliferation and complexity of rootkits," McAfee concludes.

Over recent months, security firms such as F-Secure and Sunbelt Software have used blogs to exchange ideas with the wider public about their security research efforts. According to McAfee, hackers are doing much the same.

What's sauce for the goose is sauce for the gander, it would seem. ®

  • Israel plans ‘Cyber-Dome’ to defeat digital attacks from Iran and others
    Already has 'Iron Dome' – does it need another hero?

    The new head of Israel's National Cyber Directorate (INCD) has announced the nation intends to build a "Cyber-Dome" – a national defense system to fend off digital attacks.

    Gaby Portnoy, director general of INCD, revealed plans for Cyber-Dome on Tuesday, delivering his first public speech since his appointment to the role in February. Portnoy is a 31-year veteran of the Israeli Defense Forces, which he exited as a brigadier general after also serving as head of operations for the Intelligence Corps, and leading visual intelligence team Unit 9900.

    "The Cyber-Dome will elevate national cyber security by implementing new mechanisms in the national cyber perimeter, reducing the harm from cyber attacks at scale," Portnoy told a conference in Tel Aviv. "The Cyber-Dome will also provide tools and services to elevate the protection of the national assets as a whole. The Dome is a new big data, AI, overall approach to proactive defense. It will synchronize nation-level real-time detection, analysis, and mitigation of threats."

  • Intel to sell Massachusetts R&D site, once home to its only New England fab
    End of another era as former DEC facility faces demolition

    As Intel gets ready to build fabs in Arizona and Ohio, the x86 giant is planning to offload a 149-acre historic research and development site in Massachusetts that was once home to the company's only chip manufacturing plant in New England.

    An Intel spokesperson confirmed on Wednesday to The Register it plans to sell the property. The company expects to transfer the site to a new owner, a real-estate developer, next summer, whereupon it'll be torn down completely.

    The site is located at 75 Reed Rd in Hudson, Massachusetts, between Boston and Worcester. It has been home to more than 800 R&D employees, according to Intel. The spokesperson told us the US giant will move its Hudson employees to a facility it's leasing in Harvard, Massachusetts, about 13 miles away.

  • Start using Modern Auth now for Exchange Online
    Before Microsoft shutters basic logins in a few months

    The US government is pushing federal agencies and private corporations to adopt the Modern Authentication method in Exchange Online before Microsoft starts shutting down Basic Authentication from the first day of October.

    In an advisory [PDF] this week, Uncle Sam's Cybersecurity and Infrastructure Security Agency (CISA) noted that while federal executive civilian branch (FCEB) agencies – which includes such organizations as the Federal Communications Commission, Federal Trade Commission, and such departments as Homeland Security, Justice, Treasury, and State – are required to make the change, all organizations should make the switch from Basic Authentication.

    "Federal agencies should determine their use of Basic Auth and migrate users and applications to Modern Auth," CISA wrote. "After completing the migration to Modern Auth, agencies should block Basic Auth."

  • City-killing asteroid won't hit Earth in 2052 after all
    ESA ruins our day with some bad news

    An asteroid predicted to hit Earth in 2052 has, for now, been removed from the European Space Agency's list of rocks to be worried about.

    Asteroid 2021 QM1 was described by ESA as "the riskiest asteroid known to humankind," at least among asteroids discovered in the past year. QM1 was spotted in August 2021 by Arizona-based Mount Lemmon observatory, and additional observations only made its path appear more threatening.

    "We could see its future paths around the Sun, and in 2052 it could come dangerously close to Earth. The more the asteroid was observed, the greater that risk became," said ESA Head of Planetary Defense Richard Moissl.

  • Why Wi-Fi 6 and 6E will connect factories of the future
    Tech body pushes reliability, cost savings of next-gen wireless comms for IIoT – not a typo

    Wi-Fi 6 and 6E are being promoted as technologies for enabling industrial automation and the Industrial Internet of Things (IIoT) thanks to features that provide more reliable communications and reduced costs compared with wired network alternatives, at least according to the Wireless Broadband Alliance (WBA).

    The WBA’s Wi-Fi 6/6E for IIoT working group, led by Cisco, Deutsche Telekom, and Intel, has pulled together ideas on the future of networked devices in factories and written it all up in a “Wi-Fi 6/6E for Industrial IoT: Enabling Wi-Fi Determinism in an IoT World” manifesto.

    The detailed whitepaper makes the case that wireless communications has become the preferred way to network sensors as part of IIoT deployments because it's faster and cheaper than fiber or copper infrastructure. The alliance is a collection of technology companies and service providers that work together on developing standards, coming up with certifications and guidelines, advocating for stuff that they want, and so on.
