Chinese hackers exploited years-old software flaws to break into telecom giants

The success of the campaign is a dramatic picture of malicious software flaws that persist even years after it was discovered and made public. Zero-Day Attacks ઉપયોગ Hacks અગાઉ using previously unknown vulnerabilities પંચ packs a punch and demands attention. But known shortcomings remain strong as networks and devices can be difficult to update and secure with limited resources, personnel and money.

Rob Joyce, a senior official at the National Security Agency, explained that the advisory was intended to provide step-by-step instructions for finding and removing hackers. “Kicking [the Chinese hackers] Outside, we need to understand tradecraft and find it just outside of initial access, “he said. Tweeted,

Joyce echoed the advice, which directed telecom companies to implement basic cyber security practices, such as keeping key systems up-to-date, enabling multi-factor authentication and reducing internal network connectivity over the Internet.

According to the advisory, Chinese espionage was usually started by hackers using surveillance of target networks and open source scanning tools such as routerssplots and routerscans to find out the mac, models, versions and known vulnerabilities of routers and networking devices.

With that knowledge, hackers were able to use old but unpredictable vulnerabilities to access the network and, from there, access servers providing authentication and identification for targeted organizations. They stole usernames and passwords, reconfigured routers, and successfully extracted and copied targeted network traffic to their own machines. With these tricks, they were able to spy on everything going on inside the organization.

The hackers then turned around and deleted the log files on each machine they touched in an attempt to destroy the evidence of the attack. U.S. officials did not explain how they finally found out about the hacks, despite attempts by the attackers to cover their tracks.

The Americans also left out details of what specific hacking groups they were accusing, as well as evidence that the Chinese government was responsible.

The advisory raised by the United States about China is yet another alarm. In a recent speech, FBI Deputy Director Paul Abbott said China was “more cyber-infiltrating than any other nation in the world.” The Chinese government regularly denies that it is involved in any hacking campaigns against other countries. The Chinese embassy in Washington, D.C., did not respond to a request for comment.
