New data released today indicates that trust has eroded among criminal interactions, causing a switch to ecommerce platforms and communication using Discord, which both increase user anonymization. more
The Internet and the domain name system (DNS) have become the mainstay of the new COVID sheltered world. Afilias looked at registrations in the unrestricted domain name space, with a special focus on the popular .INFO, .PRO, .MOBI and .IO domain name extensions. The data shows that the number of website and domain registrations related to COVID and Coronavirus in these extensions is flattening after a surge in March. more
The COVID-19 Pandemic is causing huge social and financial shifts, but so far, its impact on network security has gone under-reported. Yet with thousands of companies worldwide requiring millions of employees to work remotely, network administrators are seeing unprecedented changes in the ways that clients are using their networks and new threats that seek to leverage the current crisis. more
Just as we started the new year, the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency's (CISA) issued an alert. On January 6, 2020 , they warned of domain name system (DNS) hijacking and other cyber threats that may be used by nation-state threat actors to disrupt business activity and take control of vital internet assets. A familiar refrain heard in 2019 now repeating in 2020. more
For our final blog in this series, looking at the online risks associated with COVID-19, we focus on social media. The popularity of social media channels means that they are extremely susceptible to exploitation by cybercriminals and other infringers, particularly during the coronavirus crisis. In an earlier post in this series, we discussed the use of social media for the distribution of phishing-related content, but CSC has also noted marked activity relating to the creation of fake accounts. more
In part four of this series of posts looking at emerging internet content relating to coronavirus, we explore phishing. In times of crisis, cyber criminals invariably take advantage of the growing concerns of the public. In the case of the coronavirus, they have done so by sending phishing emails that play on the fears surrounding the spread of the illness. A number of reports have emerged of emails purporting to provide advice or assistance relating to COVID-19... more
While the March report from ICANN's Domain Abuse Activity Reporting system show a general reduction in second-level gTLD domain names identified as being used in phishing, malware distribution, and botnet command and control, it has been widely reported that criminals are taking advantage of the global COVID-19 pandemic by launching malicious online campaigns. There have also been numerous reports of spikes in the use of COVID-19-related domain names for DNS Abuse. more
Now that we are all working from home (WFH), the need for encryption must also increase in priority and awareness. Zoom's popular video conferencing solution got in hot water because they promised "end-to-end" encryption but didn't deliver on it - prompting some organizations to ban it from use altogether. Encryption protects confidential information from being exposed in transmission, providing a secure way for the intended recipient to get the information without snooping by others. more
In part three of this series of posts looking at emerging internet content relating to coronavirus, we turn our attention to mobile apps - another digital content channel that can be used by criminals to take advantage of people's fears about the health emergency for their own gain.One of the most common attack vectors we have found in our analysis is the use of apps purporting to track global progression of COVID-19, or provide other information, but which instead incorporate malicious content. more
During the last week, Google says it has been seeing 18 million malware and phishing emails related to COVID-19 daily. This, the company reported today, "is in addition to more than 240 million COVID-related daily spam messages." more
Nobody loves a good crisis more than a hacker and, by anyone's definition, coronavirus is a big, fat stinking crisis that almost everyone on earth is sitting in the middle of. For most of us, a crisis brings out the best. First responders and the healthcare systems are replete with stories of superhuman sacrifice and commitment to others. Unfortunately, it is this commitment to the work at hand that puts cybersecurity on the back burner and increases the chance of a breach, break-in, or general mischief. more
In the midst of the coronavirus crisis and the partial or total quarantines happening around the world, more people are turning to eCommerce for their purchases. This, combined with the increased demand for healthcare and healthcare-related products, is causing surges of activity on online marketplaces. Perhaps least surprising is the growth in the number of listings for cleaning and hygiene products (e.g., hand sanitizer), as well as facemasks... more
In recent weeks we've seen a range of press articles, security blogposts and public statements addressing real or perceived issues with network capacity and the domain name system (DNS) in particular. These range from concerns about the resilience of the DNS with questions on the impact of the number of registrations to news indicating that a tidal wave of fraud and abuse is hitting the world. more
Zoom programmers made elementary security errors when coding, and did not use protective measures that compiler toolchains make available. It's not a great stretch to assume that similar flaws afflict their server implementations. While Mudge noted that Zoom's Windows and Mac clients are (possibly accidentally) somewhat safer than the Linux client, I suspect that their servers run on Linux.Were they written with similar lack of attention to security? more
It is a well understood scientific fact that Internet voting in public elections is not securable: "the Internet should not be used for the return of marked ballots. ... [N]o known technology guarantees the secrecy, security, and verifiability of a marked ballot transmitted over the Internet." But can legislatures (city councils, county boards, or the U.S. Congress) safely vote by Internet? Perhaps they can. To understand why, let's examine two important differences between legislature votes and public elections. more
