A new Android malware operation called RedWing is being rented out on Telegram as a ready-made bank-fraud service. It lets even low-skill criminals take over a victim's phone, steal their banking logins, and capture the one-time codes that protect their accounts. Zimperium's zLabs, which found the operation, says it looks like a new variant of Oblivion, a $300-a-month rent-a-malware tool

A critical flaw in Google's Dialogflow CX could have let an attacker with edit rights on one Code Block-enabled agent compromise other Code Block-enabled agents in the same Google Cloud project. From there, they could read live conversations, steal the data users shared, and make the bots send attacker-written messages, including requests to re-enter a password. Security firm Varonis found it

The flaw allows an unauthenticated attacker to craft a GitHub Issue in an org's public repository and then silently pull data from its private repos, too.

A Microsoft 365 device code phishing campaign has been observed leveraging collaboration-themed lures to take control of victim accounts between the last week of June 2026 and into early July, per findings from ZeroBEC. "The campaign did not depend on a fake Microsoft password page. It used a malicious collaboration-style lure to push users into the legitimate Microsoft device login experience,

A public issue can trick GitHub Agentic Workflows into leaking the contents of an organization's private repositories, researchers at Noma Security have shown. The attacker needs only to open a normal-looking issue on a public repository, with no stolen credentials and no access to the organization. If that organization has given the agent read access across its repositories, private ones
