On Thursday night, Microsoft confirmed that two unpatched Exchange Server vulnerabilities are being actively exploited by cybercriminals. The vulnerabilities were discovered by a Vietnamese cybersecurity firm named GTSC, which claims in a post on its website that the two zero days have been used in attacks against its customers since early August. Although the flaws only affect on-premises Exchange servers to which an attacker has authenticated access, according to GTSC, zero-days can be chained together to create backdoors into the vulnerable server. “The vulnerability is found to be so critical that it allows the attacker to do RCE [remote code execution] on the compromised system,” the researchers said.
In a blog post, Microsoft described the first flaw as a server-side request forgery (SSRF) vulnerability, and the second as “an attack that allows remote code execution on a vulnerable server when PowerShell is accessible to attacker”. The message also provides guidance on how on-premises Microsoft Exchange customers should mitigate the attack.
Botched developments and CIA negligence partially enabled Iranian intelligence services to identify and capture informants who risked their lives to provide information to the United States, according to Reuters. The year-long investigation follows the story of six Iranian men who were imprisoned as part of an aggressive counterintelligence operation by Iran that began in 2009. The men were partially unmasked by what Reuters describes as a flawed web-based secret communications system that led to the arrest and execution of dozens of CIA informants in Iran and China. In 2018, Yahoo News reported on the system.
Because the CIA appeared to have purchased web hosting space in bulk from the same provider, Reuters was able to list hundreds of secret CIA websites intended to facilitate communications between informants around the world and their CIA handlers. . The sites, which are no longer active, were devoted to topics such as beauty, fitness and entertainment. Among them, according to Reuters, was a star wars fanpage. Two former CIA officials told the news agency that each fake website was assigned to a single spy to limit the exposure of the entire network in case a single operative was captured.
Former CIA counterintelligence chief James Olson told Reuters: “If we are negligent, if we are reckless and have been penetrated, then shame on us.”

The FBI arrested Dalke on Wednesday when he arrived at Union Station in downtown Denver to deliver classified documents to the undercover agent. If found guilty, he faces life in prison or the death penalty.
