Cybersecurity researchers are calling attention to what they say is a “recurring social engineering pattern” across hundreds of cases in which threat actors use Microsoft Teams’ external chat creation feature to conduct impersonation scams or to deliver malware.

“A consistent pattern of attacker behavior has emerged across these incidents: the use of the same throwaway tenants, the same ‘IT

This2Shell, That2Shell, Everything2Shell. That’s pretty much how the last week went. Critical bugs that let attackers run code remotely are showing up everywhere. Hackers are scanning for targets, some flaws are already being used in attacks, and security teams have more urgent patches than they can keep up with.

And that’s not even the full story. A leaked key led to a software supply-chain

The individuals called victims and persuaded them to install an app and scan their credit cards to loot their bank accounts.

LiteLLM, an open-source tool widely used by artificial intelligence developers, said a key accidentally exposed in May was behind a supply-chain attack that is believed to have hit tens of thousands of users last week.

Every SOC struggles with a pile of alerts. Very few of those alerts explain how an attack started or how it progressed. Network data, like that from a network detection and response (NDR) platform, connects individual alerts into one timeline, and it feeds the defensive systems that can tie all events together into one coordinated view.

SOC teams often first see the shape of an intrusion

A rentable Android spyware kit called uCreator takes over Telegram and WeChat accounts by hiding its code inside working copies of the two apps, researcher Ovi found. It only reaches people who install one of these tampered copies, spread outside the official app stores, or who run WeChat inside the kit makers’ own container app.

The kit’s Telegram part matches Baohuo, a backdoor that Doctor

Cybersecurity researchers have disclosed a Microsoft 365 campaign that has been observed leveraging an adversary-in-the-middle (AitM) relay to capture sign-in sessions and then replay the stolen tokens to break into email accounts at 79 organizations.

Huntress, which observed the activity between July 14 and September 22, 2026, said it detected 497 successful Microsoft 365 sign-in events across

An automated campaign is using stolen GitHub tokens to plant workflows that print a repository’s secrets into its GitHub Actions logs, which the attackers then download before deleting the runs. The attacks have succeeded in private repositories and GitHub Enterprise environments, according to an analysis by cloud security company Wiz.
