TrickBot adds firmware tool that researchers say could lead to ‘bricking’ devices

Posted on by

The malicious software known as TrickBot has morphed again, this time with a module that probes booting process firmware for vulnerabilities, possibly setting the stage for attacks that could ultimately destroy devices, researchers say. Two cybersecurity companies, Eclypsium and Advanced Intelligence (Advintel), dubbed the TrickBot add-on module “TrickBoot,” since it targets the UEFI/BIOS firmware. Firmware is permanent code programmed into a hardware device, while UEFI and BIOS are two kinds of specifications that manage a device’s start-up. TrickBoot, then, is s a “significant step in the evolution of TrickBot,” the researchers say, that could make TrickBot especially pesty. “Since firmware is stored on the motherboard as opposed to the system drives, these threats can provide attackers with ongoing persistence even if a system is re-imaged or a hard drive is replaced,” they wrote.”Equally impactful, if firmware is used to brick a device, the recovery scenarios are markedly different (and more difficult) than recovery […]

Researchers suggest 25 countries are using a kind of mobile spyware that monitors texts, location

Posted on by

A private surveillance firm that exploits mobile network vulnerabilities to spy on calls, texts and location data is doing business with at least 25 governments around the globe, including some with histories of human rights abuses, concludes a report released Tuesday. The findings from the University of Toronto’s Citizen Lab scrutinize the work of the company Circles, which is a sister firm of the Israeli software surveillance broker NSO Group. Human rights activists frequently criticize NSO Group for selling its equipment to repressive regimes, a charge it rejects, even as it is the subject of a lawsuit from Facebook, which alleges that attackers used NSO Group tech to spy on thousands of WhatsApp users. The countries Citizen Lab identified as “likely” customers of Circles: Australia, Belgium, Botswana, Chile, Denmark, Ecuador, El Salvador, Estonia, Equatorial Guinea, Guatemala, Honduras, Indonesia, Israel, Kenya, Malaysia, Mexico, Morocco, Nigeria, Peru, Serbia, Thailand, the United Arab Emirates, Vietnam, Zambia and Zimbabwe.

Supreme Court considers scope of federal anti-hacking law in biggest cyber case to date

Posted on by

Several U.S. Supreme Court justices, including some of President Donald Trump’s appointees, skeptically questioned a broad interpretation of the main federal anti-hacking law during oral arguments Monday. The hearing represented one of the final steps in the biggest case to come before the nation’s highest court involving the Computer Fraud and Abuse Act (CFAA), written in the 1980s. The case centers on when an individual “exceeds authorized access” to a computer, as defined by that law. The law has long held a contentious place in the cybersecurity world, where it’s viewed as hopelessly vague, outdated and overly punitive. One CFAA prosecution that drew particular criticism was that of Aaron Swartz, an internet activist who took his own life before he was scheduled to stand trial for allegedly downloading articles from an academic database, in a case where he faced decades in prison if convicted. The case now before the Supreme Court involves defendant Nathan […]

It’s hard to keep a big botnet down: TrickBot sputters back toward full health

Posted on by

Mounting evidence suggests that TrickBot, the vast botnet that both U.S. Cyber Command and a Microsoft-led coalition sought to disable around the 2020 elections, is on the mend and evolving. The separate campaigns featured Microsoft going to court to disable IP addresses associated with TrickBot command and control servers, as Cyber Command’s operation also targeted command and control servers.  Hints of its rebound began in late October, shortly after signs of success in the bids to dismantle the TrickBot network of zombie computers. While Cyber Command and Microsoft always billed their assaults as a disruption rather than a full takedown, the TrickBot comeback is proof that it’s difficult to kill a botnet outright. Botnets are dangerous because they can be used to conduct a range of harmful activities, like distributed denial of service attacks that overwhelm a site with traffic or ransomware attacks, the latter of which were a major issue of concern for U.S. national security […]

Accused email scammers busted in Nigeria for alleged fraud against 50,000 victims

Posted on by

An Interpol-helmed operation led to the arrest of three suspected cybercriminal gang members in Nigeria whose outfit has allegedly targeted victims in more than 150 countries, including schemes that involved offering COVID-19 aid. The sting, announced Wednesday, was part of Operation Falcon, a year-long investigation that teamed with cybersecurity company Group-IB and the Nigeria Police Force. “This group was running a well-established criminal business model,” said Craig Jones, Interpol’s cybercrime director. “From infiltration to cashing in, they used a multitude of tools and techniques to generate maximum profits.” The gang, dubbed TMT, is divided into numerous subgroups, according to Vesta Matveeva, head of Group-IB’s APAC Cyber Investigations Team. The three suspects arrested in Lagos tallied 50,000 victims in government and industry, the company said. Matveeva said via email that TMT overall might have compromised more than 500,000 victims since 2017. TMT’s speciality is business email compromise (BEC), where the attackers pose […]

Home Depot to pay states $17.5 million over massive 2014 data breach

Posted on by

U.S. states have reached a settlement over the mammoth 2014 Home Depot breach that will net them $17.5 million, plus an agreement from the home improvement retailer to strengthen its data security practices. The breach, which compromised 56 million payment card across the U.S., still ranks among the biggest data breaches ever. It’s been an expensive cleanup. Years after the attack, Home Depot estimated the cost at about $179 million and said it was likely to continue growing. The settlement with 46 states and the District of Columbia adds to the tally. It also comes one month after Home Depot suffered a data breach of its Canadian customers that was much smaller than the 2014 breach that was the subject of the U.S. settlement. “Instead of building a secure system, The Home Depot failed to protect consumers and put their data at risk,” New York Attorney General Letitia James said about the 2014 incident.

After years of work, Congress passes ‘internet of things’ cybersecurity bill — and it’s kind of a big deal

Posted on by

Congress last week did something that it rarely does: It passed a meaningful cybersecurity bill. The legislation is aimed at enhancing the safeguards of internet-connected devices — also known as the internet of things (IoT) — such as smart sensors that monitor water quality or control ships in waterway locks. The bill is also a major step toward the federal government encouraging vulnerability disclosure policies that implement programs for organizations to work with security researchers to fix software flaws. “It is arguably the most significant U.S. IoT-specific cybersecurity law to date, as well as the most significant law promoting coordinated vulnerability disclosure in the private sector to date,” said Harley Geiger, director of public policy at Rapid7, a cybersecurity company. All it took to get across the finish line was more than three years of bipartisan work, encroaching state and foreign government IoT rules, a ticking legislative clock, goodwill toward […]

Ghost in the machine: Researchers find Webex vulnerabilities allow hidden visitors

Posted on by

Halloween may have been last month, but IBM researchers revealed Wednesday that they discovered a way ghosts could haunt Cisco Webex meetings. The vulnerabilities in the video conferencing platform — since the subject of a Cisco patch — would permit uninvited guests to join a meeting without showing up on the participant list, stay in a meeting even after the host expels them and gather information about other attendees without joining. Unwelcome guests are often more commonly associated with a Webex competitor, Zoom, which led to the coining of the term “Zoombombing” and Zoom wrestling with the problem. But the IBM research shows that with so many meetings happening online during the pandemic, Zoom isn’t alone. Webex registered a record 324 million users in March, and saw usage grow 451% from mid-February to mid-June. IBM Research found that invaders could exploit the “handshake” process whereby Webex connects meeting participants. “A malicious actor […]

Financial system not keeping up with cyberthreats, new report says

Posted on by

Four years after the biggest bank hack ever, the global financial system remains vulnerable to cyberattacks that could cause severe disruptions, according to a report Wednesday that draws advice from government officials, the financial industry and other experts. The assessment from the Carnegie Endowment for International Peace and the Word Economic Forum is the culmination of years of work, with touchstones ranging from the 2016 Bangladesh Bank heist where hackers made off with $81 million to a recent Chilean bank ransomware attack that shut down all of its branches. “Our big concern is that if you look at what’s happened during the pandemic, but even before with the escalating threat that’s targeting the financial system from the Bangladesh incident to the Chile outage back in September, we’re clearly not keeping up with the threat and how quickly it’s evolving,” said Tim Maurer, director of Carnegie’s Cyber Policy Initiative. “The government and industry need […]

Zoom pushes new tools meant to counter ‘Zoombombing’

Posted on by

Zoom on Monday unveiled a trio of security tools the video conferencing company and its users can deploy to defend against unwelcome intruders who “Zoombomb” meetings. The announcement is the latest in a blitz that began this spring, when Zoom’s daily usage skyrocket at the onset of the coronavirus outbreak, and the company admitted it was caught off guard by the resulting security woes — among them, uninvited users posting offensive materials. Last week, Zoom reached a settlement with the Federal Trade Commission over its encryption claims. The company has since begun rolling out end-to-end encryption for all users. Multiple state attorneys general also had pressed Zoom to do more about Zoombombing. The company reached an agreement with New York in May to increase security. “Suspend Participant Activities,” one of the three tools Zoom detailed in a blog post, allows Zoom hosts to pause meeting functions to report disruptive attendees. Afterward, the host can resume video, audio, screen sharing and other […]
