[HEADS UP] Google's Huge Inactive Account Deletion - What You Need to Know
Google announced an update to their inactive account policies in May. Accounts that have been inactive for a period of two years or more will start being deleted in December 2023, at the earliest.
This policy change is meant to enhance security, as abandoned accounts are more likely to be compromised and 10x less likely to have multi-factor authentication enabled. The policy applies to content within Google Workspace (Gmail, Docs, Drive, Meet, Calendar) and Google Photos.
A few ways to keep an account status active include reading or sending an email, using Google Drive, watching a YouTube video, downloading an app on the Google Play Store, using Google Search and more. Google's announcement post gives more details around affected accounts, backup instructions and more.
While account deletion isn't set to begin for several months, notification emails have started going out to account owners. We haven't seen them yet, but this is prime fodder for phishing attacks that impersonate Google. It's only a matter of time before cybercriminals use this news to scam people into going to malicious websites, where their Google account credentials can be harvested.
You should warn your users now to keep them aware of potential attacks. Any urgent account alert emails should be scrutinized closely. Instead of clicking a link in an email, it's best to go directly to Google accounts that could be affected by this policy change.
New-school security awareness training enables your users to make smarter security decisions so they can avoid falling for social engineering attacks.

Amazon Sends Email to Customers on Common Scam Tactics
We've reported on several Amazon scams, but for once, there is positive news. Amazon sent an email Thursday morning highlighting the top scams your users should watch out for:
Prime Membership Scams
Per Amazon, "These are unexpected calls/texts/emails that refer to a costly membership fee or an issue with your membership and ask you to confirm or cancel the charge. These scammers try to convince you to provide payment or bank account information in order to reinstate a membership."
Account Suspension/Deletion Scams
Per Amazon, "Scammers send texts, emails and phone calls stating that your account will be suspended or deleted and prompt you to click on a fraudulent link or verbally provide information to "verify your account." Customers who land on these pages or receive these phone calls are then lured to provide account information such as payment information or account login credentials."
Amazon noted that they will never ask you to disclose any confidential information from you over the phone or on any website other than Amazon.com.
They also included some helpful tips to identify these types of scams and how to keep your account safe online:
- Trust Amazon-owned channels - Always go through the Amazon mobile app or website when seeking customer service, tech support, or when looking to make changes to your account.
- Be wary of false urgency - Scammers may try to create a sense of urgency to persuade you to do what they're asking. Be wary any time someone tries to convince you that you must act now.
- Never pay over the phone - Amazon will never ask you to provide payment information, including gift cards (or "verification cards," as some scammers call them) for products or services over the phone.
- Verify links first - Legitimate Amazon websites contain "amazon[.com]" or "amazon[.com]/support." Go directly to our website when seeking help with Amazon devices/services, orders or to make changes to your account.
If you receive communication — a call, text, or email — that you think may not be from Amazon, you can report it at amazon[.com]/reportascam. Remember, your employees are your last line of defense. Teach your users how to spot and report these popular scams.

Advanced Phishing Campaign Exploits 3rd Parties
Researchers at BlueVoyant warn that attackers are increasingly adding an extra step to their phishing campaigns, impersonating third parties to lend credibility to the scams.
"Third-party phishing sites…will include some characteristics of the original flow, with an added step – the initial impersonation that establishes credibility to the end user is a service that is not connected to the targeted organization," the researchers write.
"Furthermore, the third-party phishing page itself won't ask the victim to submit their personal credentials. The fraud occurs in the final phishing page to which the client has been redirected, impersonating the chosen financial institution."
BlueVoyant has seen a significant spike in this technique over the past year. "Third-party phishing websites are spread on a massive scale across the internet," the researchers write. "Over the past year, BlueVoyant has witnessed a major increase in the number of phishing sites originating in third-party phishing campaigns.
"One major European client saw an increase from just 2% of all detected phishing attacks in 2022 to 21% in 2023... It now permeates across a number of sectors: e-commerce, logistics and shipping, mobile carriers, government institutions, payment transaction platforms, and more."
The use of intermediate sites helps the attackers avoid detection by security tools. "Third-party phishing adds a new wrinkle to the oldest trick in the book," the researchers write. "Intermediary sites directing victims to various different phishing sites provides two benefits to attackers: it allows them to cast a wider net and catch more fish (so to speak), and it provides another degree between them and threat hunters who may be on their trail.
"We've previously published research highlighting how attackers use redirects as an evasion mechanism – third-party phishing builds on that concept, while also giving the threat actor a greater chance of ensnaring their targets."

CISA Discovers Spear Phishing and Valid Account Compromise Are the Most Common Attack Vectors
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has found that compromise of valid accounts and spear phishing attacks were the two most common vectors of initial access in 2022, Decipher reports. Valid accounts were compromised in 54% of successful attacks.
"Valid accounts can be former employee accounts that have not been removed from the active directory or default administrator accounts," CISA said. "When organizations do not change default passwords, threat actors can compromise a valid administrator account.
"In many cases, this attack technique is possible because the valid account allowed unauthorized users to install or execute insecure software (such as unpatched or out-of-date software) on a system or network."
The report found that spear phishing links were successful in 33% of attacks.
"Successful spear phishing requires an attacker's malicious email to pass through network border protections and deliver malware to execute on the local host," CISA says. "Host-level protection stops spear phishing attempts as they pass through network perimeter protection. At the network border level, CISA observed 13% of spear phishing attempts blocked.
At the host or endpoint level, CISA observed 78% of links or attachments blocked, preventing the execution of a malicious activity. A cyber threat actor's success rate with this type of attack depends on factors, such as the perceived authenticity of the email's content and presentation, host protections (e.g., antivirus and malware detection software), and the network's boundary protection mechanisms."
CISA offers the following recommendations for organizations to defend themselves against these attacks:
- "Implement a secure password policy requiring phishing-resistant multi-factor authentication (MFA) for remote access, strong passwords, unique credentials, and the separation of user and privileged accounts, effectively revoking unnecessary or inactive accounts.
- "Configure email servers to filter out and block emails with malicious indicators and implement authentication protocols, such as Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to prevent spoofed or modified emails.
- "Implement a phishing awareness training program that includes guidance on identifying phishing attacks and how personnel should report suspected phishing attempts and verified incidents."
New-school security awareness training can teach your employees to follow security best practices so they can avoid falling for social engineering attacks.

Bad Actor Uses Fake Android Chat to Install Malware
Researchers at CYFIRMA warn that the Bahamut threat actor is using a malicious Android app to deliver malware.
"The suspected Android malware, known initially as 'CoverIm' was delivered to victims via WhatsApp, and was found to be disguised as a dummy chatting application named 'SafeChat,'" the researchers write. "The user interface of this app successfully deceives users into believing its authenticity, allowing the threat actor to extract all the necessary information, before the victim realizes that the app is a dummy, the malware cleverly exploits unsuspecting Android Libraries to extract and transmit data to a command-and-control server."
After the app is installed, it will continually ask the user to grant it accessibility permissions. "Once the user clicks on 'Allow'...the app takes the user to the accessibility page and asks the victim to enable accessibility for the Safe Chat app," the researchers write. "Once the accessibility is on, then the malware will capture activity on screen including keystrokes. Until it is enabled, the app will throw a pop-up message again and again."
While Bahamut was previously believed to be a mercenary group, CYFIRMA believes the threat actor is based in India and works for a single nation-state government.
"In this specific attack, the threat actor conducted targeted spear messaging attacks on WhatsApp Messenger, focusing on individuals in the South Asia region," the researchers write. "The malicious payload was delivered directly through WhatsApp chat. The attack on the individual served the interest of one nation state government.
"The nature of this attack, along with previous incidents involving APT Bahamut, possibly indicate that it was carried out to serve the interests of one nation state government. Notably, APT Bahamut has previously targeted Khalistan supporters, advocating for a separate nation, posing an external threat to India."
