In the fast-paced world of cybersecurity, cybercriminals are always on the run, launching massive and sophisticated cyberattacks using new variants of existing malware. One such case that has come to notice in the past 24 hours is the use of the Glupteba backdoor. The malware which first appeared in 2014, has now been evolved to include several evasion tricks and data-stealing capabilities. This new variant leverages living-off-the-land technique and creates a specific command line triggers to bypass security solutions. Among the new capabilities, the new Glupteba version can exfiltrate sensitive data, mine cryptocurrencies and steal browser information.
The past 24 hours also saw Google halting the rollout of its Chrome 79 - which came with fixes for 51 flaws - on Android. The decision has been taken after developers uncovered a major bug that is responsible for data loss for a few apps. The bug occurred during the update process from Chrome 78 to Chrome 79.
In other development, TP-Link has patched a zero-day vulnerability in its Archer C5 (v4) routers that run firmware version 3.16.0 0.9.1 v600c.0 Build 180124 Rel.28919n. The flaw could be exploited to take control of the router’s configuration via Telnet on the LAN.

Npm patches two bugs
Two serious vulnerabilities discovered in the Npm CLI has been patched recently. One of these flaws allowed an attack known as binary planting. The flaw affects Npm CLI versions prior to 6.13.3. The second vulnerability exists in bin-links, which is an Npm package that manages links from the bin field to the file in ./node_modules/.bin/.
