Location-enabled tech designed to make our lives easier is often exploited by domestic abusers. Refuge, a UK nonprofit, helps women to leave abusive relationships, secure their devices, and stay safe.

Pick up any piece of tech and Emma Pickering knows how it can be used to abuse, harass, and stalk women. Amazon’s Ring home doorbell cameras can monitor when someone leaves the house and who is visiting them. Until recently, Netflix showed the IP addresses where users were logged in, allowing their location to be tracked. Workout apps and websites such as Strava show where and when people are exercising. And abusers often slip small GPS trackers or audio recorders into women’s belongings or attach them to their cars.

“Perpetrators buy them in bulk, and they’ll buy probably 60 very cheaply; they’re very small and discrete,” says Pickering, who works at Refuge, the UK’s largest domestic abuse organization, where she heads a team that helps women secure their devices. Pickering says that in one case “over 200” recording devices were found in a woman’s home.

Refuge launched its Technology-Facilitated Abuse and Economic Empowerment Team in 2017, amid a surge of abusers weaponizing apps, devices, and online services to harm women. The charity helps women and their children leave abusive relationships, providing emergency accommodation, legal help, financial aid, and more. Almost every case now involves technology in some form, Pickering says, and the issue is so serious that every person the organization places into a refuge goes through a tech assessment to secure their accounts. The tech abuse team, which is made up of 11 people, is the only one of its kind in the UK and just one of a handful of similar organizations around the world.

Technology-facilitated abuse can range from harassment via phone call or text message to logging into someone’s social media and email accounts without their permission, which allows abusers to read, delete or send messages. In more extreme cases, they might install “stalkerware” on victims’ phones to monitor every tap and scroll. Nonconsensual image-sharing, commonly known as “revenge porn,” and economic abuse, where money and banking apps may be controlled by an abuser, are also frequent. In August, a report from MPs in the UK concluded that tech abuse is becoming “increasingly common.”

Pickering says her team primarily focuses on helping people in the more severe cases. “Firstly, we need to establish if it’s safe to speak to them on their device,” she says. If it isn’t, Refuge will send women a burner phone and then set them up with a new email address, using the encrypted email service Proton Mail, before sending them extra information. It’s the start of a meticulous process—known as an “attack assessment” by the team—to secure accounts and devices.

“We go through everything,” Pickering says. Refuge will ask the person they are helping to list every device and online account they and any children have. These can easily number into the hundreds. “Within the home, if they’ve fled the relationship, we also need to check anything they’ve left behind to unsync from any devices or accounts that they could still be using back home.” This will include products like Google Home Hubs, and Amazon’s Ring doorbells and Alexa, and it requires checking who set up the devices and is the administrator of the accounts, as well as which names phone contracts are in. From there, a safety plan is created, Pickering says. This can include going through the accounts and checking settings for who has access to them, removing devices connected to accounts, using secure passwords, and setting up measures such as two-factor authentication. On average, Pickering says, it can take three weeks to get through the entire process, although more complex cases take much longer.

“I don’t think people realize how serious it is, the consequences for perpetrators to have access to this information, to see that there’s evidence in someone’s phone that they’re planning to leave a relationship, read emails about financial settlements, child contact orders—it puts someone at really significant risk,” Pickering says. Even for those in nonabusive relationships, the charity has created a digital breakup tool with cybersecurity firm Avast to detail the process of separating everything from delivery apps to gaming accounts from former partners.

While the technology itself isn’t usually the problem—it’s how abusers use it to harass their victims that creates the issues—Pickering says tech companies don’t put enough thought into how their services can be used maliciously. They also don’t put enough effort into preventing such abuses. They’re not “considering having features built in that can mitigate these risks,” she says.

For instance, Apple launched its small AirTag GPS tracker without many safety features, and dozens of people have subsequently reported being tracked by the devices. (The company has made some improvements and is now working with other tracker manufacturers to make it easier to identify trackers someone has placed on your belongings). One of the biggest issues currently, Pickering says, is satellite navigation systems within cars. “My car, for instance, if I drive it somewhere, it’s connected to an app, and I don’t know how many people are on my app, it doesn’t give me notifications,” she says. There are also boundary settings that can alert a vehicle’s owner if it travels beyond a specific set of locations.

Aside from designing products better, tech companies need to make it easier for people to understand the settings on their phone and digital accounts. “Many people come to us and their confidence around tech is very limited,” Pickering says. “We have to do a lot of work with them initially to make them feel comfortable.”

While tech abuse is rising, Pickering aims to increase understanding around the problem and tackle some of the issues at its roots. “We’ve got a really big ambition to train the police,” she says, adding that officers often don’t know what to look for in cases of tech abuse and may not take issues seriously. The Refuge team has already worked with one tech company, which she says she cannot name due to an NDA, to advise on safety. “Amazon and Google could work with us,” Pickering says. “And we could help make sure that their products are developed with safety in mind.”

Cloud Security / Cyber Threat

Microsoft has detailed a new campaign in which attackers unsuccessfully attempted to move laterally to a cloud environment through a SQL Server instance.

"The attackers initially exploited a SQL injection vulnerability in an application within the target's environment," security researchers Sunders Bruskin, Hagai Ran Kestenberg, and Fady Nasereldeen said in a Tuesday report.

"This allowed the attacker to gain access and elevated permissions on a Microsoft SQL Server instance deployed in Azure Virtual Machine (VM)."

In the next stage, the threat actors leveraged the new permissions to attempt to move laterally to additional cloud resources by abusing the server's cloud identity, which may possess elevated permissions to likely carry out various malicious actions in the cloud that the identity has access to.

Microsoft said it did not find any evidence to suggest that the attackers successfully moved laterally to the cloud resources using the technique.

"Cloud services like Azure use managed identities for allocating identities to the various cloud resources," the researchers said. "Those identities are used for authentication with other cloud resources and services."

The starting point of the attack chain is an SQL injection against the database server that allows the adversary to run queries to gather information about the host, databases, and network configuration.

In the observed intrusions, it's suspected that the application targeted with the SQL injection vulnerability had elevated permissions, which permitted the attackers to enable the xp\_cmdshell option to launch operating system commands to proceed to the next phase.

This included conducting reconnaissance, downloading executables and PowerShell scripts, and setting up persistence via a scheduled task to start a backdoor script.

Data exfiltration is achieved by taking advantage of a publicly accessible tool called webhook\[.\]site in an effort to stay under the radar, since outgoing traffic to the service is deemed legitimate and unlikely to be flagged.

"The attackers tried utilizing the cloud identity of the SQL Server instance by accessing the \[instance metadata service\] and obtaining the cloud identity access key," the researchers said. "The request to IMDS identity's endpoint returns the security credentials (identity token) for the cloud identity."

The ultimate goal of the operation appears to have been to abuse the token to perform various operations on cloud resources, including lateral movement across the cloud environment, although it ended in failure due to an unspecified error.

The development underscores the growing sophistication of cloud-based attack techniques, with bad actors constantly on the lookout for over-privileged processes, accounts, managed identities, and database connections to conduct further malicious activities.

"This is a technique we are familiar with in other cloud services such as VMs and Kubernetes cluster but haven't seen before in SQL Server instances," the researchers concluded.

"Not properly securing cloud identities can expose SQL Server instances and cloud resources to similar risks. This method provides an opportunity for the attackers to achieve greater impact not only on the SQL Server instances but also on the associated cloud resources."

III. Impact A user with write access to files on a msdosfs file system may be able to read unintended data (for example, from a previously deleted file). IV. Workaround No workaround is available. V. Solution Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, and reboot. Perform one of the following: 1) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the amd64, i386, or (on FreeBSD 13 and later) arm64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install # shutdown -r +10min "Rebooting for a security update" 2) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. \[FreeBSD 13.2\] # fetch https://security.FreeBSD.org/patches/SA-23:12/msdosfs.13.2.patch # fetch https://security.FreeBSD.org/patches/SA-23:12/msdosfs.13.2.patch.asc # gpg --verify msdosfs.13.2.patch.asc \[FreeBSD 12.4\] # fetch https://security.FreeBSD.org/patches/SA-23:12/msdosfs.12.4.patch # fetch https://security.FreeBSD.org/patches/SA-23:12/msdosfs.12.4.patch.asc # gpg --verify msdosfs.12.4.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile your kernel as described in and reboot the system. VI. Correction details This issue is corrected by the corresponding Git commit hash or Subversion revision number in the following stable and release branches: Branch/path Hash Revision - ------------------------------------------------------------------------- stable/13/ 868f3eadc5e0 stable/13-n255824 releng/13.2/ 7d08a7e6908b releng/13.2-n254635 stable/12/ r373207 releng/12.4/ r373233 - ------------------------------------------------------------------------- For FreeBSD 13 and later: Run the following command to see which files were modified by a particular commit: # git show --stat Or visit the following URL, replacing NNNNNN with the hash: To determine the commit count in a working tree (for comparison against nNNNNNN in the table above), run: # git rev-list --count --first-parent HEAD For FreeBSD 12 and earlier: Run the following command to see which files were modified by a particular revision, replacing NNNNNN with the revision number: # svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NNNNNN with the revision number: VII.
