Salesloft Takes Drift Offline After OAuth Token Theft Hits Hundreds of Organizations

Salesloft Takes Drift Offline After OAuth Token Theft Hits Hundreds of Organizations

9月 03, 2025 Data Breach / Threat Intelligence,
Salesloft on Tuesday announced that it's taking Drift temporarily offline "in the very near future," as multiple companies have been ensnared in a far-reaching supply chain attack spree targeting the marketing software-as-a-service product, resulting in the mass theft of authentication tokens. "This will provide the fastest path forward to comprehensively review the application and build additional resiliency and security in the system to return the application to full functionality," the company said . "As a result, the Drift chatbot on customer websites will not be available, and Drift will not be accessible." The company said its top priority is to ensure the integrity and security of its systems and customers' data, and that it's working with cybersecurity partners, Mandiant and Coalition, as part of its incident response efforts. The development comes after Google Threat Intelligence Group (GTIG) and Mandiant disclosed what it said w...
Google Warns Salesloft Drift Breach Impacts All Drift Integrations Beyond Salesforce

Google Warns Salesloft Drift Breach Impacts All Drift Integrations Beyond Salesforce

8月 29, 2025 Data Breach / Salesforce
Google has revealed that the recent wave of attacks targeting Salesforce instances via Salesloft Drift is much broader in scope than previously thought, stating it impacts all integrations. "We now advise all Salesloft Drift customers to treat any and all authentication tokens stored in or connected to the Drift platform as potentially compromised," Google Threat Intelligence Group (GTIG) and Mandiant said in an updated advisory. The tech giant said the attackers also used stolen OAuth tokens to access email from a small number of Google Workspace email accounts on August 9, 2025, after compromising the OAuth tokens for the "Drift Email" integration. It's worth noting that this is not a compromise of Google Workspace or Alphabet itself. "The only accounts that were potentially accessed were those that had been specifically configured to integrate with Salesloft; the actor would not have been able to access any other accounts on a customer's Worksp...
Cybercriminals Deploy CORNFLAKE.V3 Backdoor via ClickFix Tactic and Fake CAPTCHA Pages

Cybercriminals Deploy CORNFLAKE.V3 Backdoor via ClickFix Tactic and Fake CAPTCHA Pages

8月 21, 2025 Malware / Cryptocurrency
Threat actors have been observed leveraging the deceptive social engineering tactic known as ClickFix to deploy a versatile backdoor codenamed CORNFLAKE.V3. Google-owned Mandiant described the activity, which it tracks as UNC5518, as part of an access-as-a-service scheme that employs fake CAPTCHA pages as lures to trick users into providing initial access to their systems, which is then monetized by other threat groups. "The initial infection vector, dubbed ClickFix, involves luring users on compromised websites to copy a malicious PowerShell script and execute it via the Windows Run dialog box," Google said in a report published today. The access provided by UNC5518 is assessed to be leveraged by at least two different hacking groups, UNC5774 and UNC4108, to initiate a multi-stage infection process and drop additional payloads - UNC5774, another financially motivated group that delivers CORNFLAKE as a way to deploy various subsequent payloads UNC4108, a threat act...

Scattered Spider Hacker Arrests Halt Attacks, But Copycat Threats Sustain Security Pressure

Scattered Spider Hacker Arrests Halt Attacks, But Copycat Threats Sustain Security Pressure

7月 30, 2025
Google Cloud's Mandiant Consulting has revealed that it has witnessed a drop in activity from the notorious Scattered Spider group, but emphasized the need for organizations to take advantage of the lull to shore up their defenses. "Since the recent arrests tied to the alleged Scattered Spider (UNC3944) members in the U.K., Mandiant Consulting hasn't observed any new intrusions directly attributable to this specific threat actor," Charles Carmakal, CTO of Mandiant Consulting at Google Cloud, told The Hacker News in a statement. "This presents a critical window of opportunity that organizations must capitalize on to thoroughly study the tactics UNC3944 wielded so effectively, assess their systems, and reinforce their security posture accordingly." Carmakal also warned businesses not to "let their guard down entirely," as other threat actors like UNC6040 are employing similar social engineering tactics as Scattered Spider to breach target netwo...

Google Warns of Scattered Spider Attacks Targeting IT Support Teams at U.S. Insurance Firms

6月 17, 2025 Threat Intelligence / Identity Security
The notorious cybercrime group known as Scattered Spider (aka UNC3944) that recently targeted various U.K. and U.S. retailers has begun to target major insurance companies, according to Google Threat Intelligence Group (GTIG). "Google Threat Intelligence Group is now aware of multiple intrusions in the U.S. which bear all the hallmarks of Scattered Spider activity," John Hultquist, chief analyst at GTIG, said in an email Monday. "We are now seeing incidents in the insurance industry. Given this actor's history of focusing on a sector at a time, the insurance industry should be on high alert, especially for social engineering schemes which target their help desks and call centers." Scattered Spider is the name assigned to an amorphous collective that's known for its use of advanced social engineering tactics to breach organizations. In recent months, the threat actors are believed to have forged an alliance with the DragonForce ransomware cartel in the ...

ToyMaker Uses LAGTOY to Sell Access to CACTUS Ransomware Gangs for Double Extortion

4月 26, 2025 Malware / Vulnerability
Cybersecurity researchers have detailed the activities of an initial access broker (IAB) dubbed ToyMaker that has been observed handing over access to double extortion ransomware gangs like CACTUS . The IAB has been assessed with medium confidence to be a financially motivated threat actor, scanning for vulnerable systems and deploying a custom malware called LAGTOY (aka HOLERUN). "LAGTOY can be used to create reverse shells and execute commands on infected endpoints," Cisco Talos researchers Joey Chen, Asheer Malhotra, Ashley Shen, Vitor Ventura, and Brandon White said . The malware was first documented by Google-owned Mandiant in late March 2023, attributing its use to a threat actor it tracks as UNC961 . The activity cluster is also known by other names such as Gold Melody and Prophet Spider. The threat actor has been observed leveraging a huge arsenal of known security flaws in internet-facing applications to obtain initial access, followed by conducting reconnai...

North Korean Hackers Target Energy and Aerospace Industries with New MISTPEN Malware

9月 18, 2024 Cyber Espionage / Malware
A North Korea-linked cyber-espionage group has been observed leveraging job-themed phishing lures to target prospective victims in energy and aerospace verticals and infect them with a previously undocumented backdoor dubbed MISTPEN. The activity cluster is being tracked by Google-owned Mandiant under the moniker UNC2970 , which it said overlaps with a threat group known as TEMP.Hermit , which is also broadly called Lazarus Group or Diamond Sleet (formerly Zinc). The threat actor has a history of targeting government, defense, telecommunications, and financial institutions worldwide since at least 2013 to collect strategic intelligence that furthers North Korean interests. It's affiliated with the Reconnaissance General Bureau (RGB). The threat intelligence firm said it has observed UNC2970 singling out various entities located in the U.S., the U.K., the Netherlands, Cyprus, Sweden, Germany, Singapore, Hong Kong, and Australia. "UNC2970 targets victims under the guise o...
North Korean Hackers Shift from Cyber Espionage to Ransomware Attacks

North Korean Hackers Shift from Cyber Espionage to Ransomware Attacks

7月 25, 2024 Malware / Cyber Espionage
A North Korea-linked threat actor known for its cyber espionage operations has gradually expanded into financially-motivated attacks that involve the deployment of ransomware, setting it apart from other nation-state hacking groups linked to the country. Google-owned Mandiant is tracking the activity cluster under a new moniker APT45 , which overlaps with names such as Andariel, Nickel Hyatt, Onyx Sleet (formerly Plutonium), Silent Chollima, and Stonefly. "APT45 is a long-running, moderately sophisticated North Korean cyber operator that has carried out espionage campaigns as early as 2009," researchers Taylor Long, Jeff Johnson, Alice Revelli, Fred Plan, and Michael Barnhart said . "APT45 has been the most frequently observed targeting critical infrastructure." It's worth mentioning that APT45, along with APT38 (aka BlueNoroff), APT43 (aka Kimsuky), and Lazarus Group (aka TEMP.Hermit), are elements within North Korea's Reconnaissance General Bureau ...

Snowflake Breach Exposes 165 Customers' Data in Ongoing Extortion Campaign

6月 11, 2024 Data Theft / Cloud Security
As many as 165 customers of Snowflake are said to have had their information potentially exposed as part of an ongoing campaign designed to facilitate data theft and extortion, indicating the operation has broader implications than previously thought. Google-owned Mandiant, which is assisting the cloud data warehousing platform in its incident response efforts, is tracking the as-yet-unclassified activity cluster under the name UNC5537 , describing it as a financially motivated threat actor. "UNC5537 is systematically compromising Snowflake customer instances using stolen customer credentials, advertising victim data for sale on cybercrime forums, and attempting to extort many of the victims," the threat intelligence firm said on Monday. "UNC5537 has targeted hundreds of organizations worldwide, and frequently extorts victims for financial gain. UNC5537 operates under various aliases on Telegram channels and cybercrime forums." There is evidence to suggest tha...
Russian Hackers Use 'WINELOADER' Malware to Target German Political Parties

Russian Hackers Use 'WINELOADER' Malware to Target German Political Parties

3月 23, 2024 Cyber Espionage / Cyber Warfare
The WINELOADER backdoor used in recent cyber attacks targeting diplomatic entities with wine-tasting phishing lures has been attributed as the handiwork of a hacking group with links to Russia's Foreign Intelligence Service (SVR), which was responsible for  breaching SolarWinds and Microsoft . The findings come from Mandiant, which said  Midnight Blizzard  (aka APT29, BlueBravo, or Cozy Bear) used the malware to target German political parties with phishing emails bearing a logo from the Christian Democratic Union (CDU) around February 26, 2024. "This is the first time we have seen this APT29 cluster target political parties, indicating a possible area of emerging operational focus beyond the  typical   targeting  of  diplomatic missions ," researchers Luke Jenkins and Dan Black  said . WINELOADER was  first disclosed  by Zscaler ThreatLabz last month as part of a cyber espionage campaign that's believed to have been ongoing since a...

China-Linked Group Breaches Networks via Connectwise, F5 Software Flaws

3月 22, 2024 Cyber Defense / Vulnerability
A China-linked threat cluster leveraged security flaws in Connectwise ScreenConnect and F5 BIG-IP software to deliver custom malware capable of delivering additional backdoors on compromised Linux hosts as part of an "aggressive" campaign. Google-owned Mandiant is  tracking  the activity under its uncategorized moniker  UNC5174  (aka Uteus or Uetus), describing it as a "former member of Chinese hacktivist collectives that has since shown indications of acting as a contractor for China's Ministry of State Security (MSS) focused on executing access operations." The threat actor is believed to have orchestrated widespread attacks against Southeast Asian and U.S. research and education institutions, Hong Kong businesses, charities and non-governmental organizations (NGOs), and U.S. and U.K. government organizations between October and November 2023, and again in February 2024 using the ScreenConnect bug. Initial access to target environments is facilitated by t...

Chinese Hackers Exploiting Ivanti VPN Flaws to Deploy New Malware

Chinese Hackers Exploiting Ivanti VPN Flaws to Deploy New Malware

2月 29, 2024 Threat intelligence / Vulnerability
At least two different suspected China-linked cyber espionage clusters, tracked as  UNC5325  and  UNC3886 , have been attributed to the exploitation of security flaws in Ivanti Connect Secure VPN appliances. UNC5325 abused  CVE-2024-21893  to deliver a wide range of new malware called LITTLELAMB.WOOLTEA, PITSTOP, PITDOG, PITJET, and PITHOOK, as well as attempted to maintain persistent access to compromised appliances, Mandiant said. The Google-owned threat intelligence firm has assessed with moderate confidence that UNC5325 is associated with UNC3886 owing to source code overlaps in LITTLELAMB.WOOLTEA and PITHOOK with malware used by the latter.
