In recent decades, MI6 has adapted to the changing global security landscape, focusing on counterterrorism, countering the proliferation of weapons of mass destruction, cyber intelligence, and tackling emerging threats. Notable events in its history include the Cambridge Five espionage scandal and the exposure of Russian spy Sergei Skripal in the UK.

Notable Operations:

1. Operation Gold: In the early 1950s, MI6 and the CIA conducted a joint operation to tunnel under East Berlin and tap into Soviet communication cables. This operation provided valuable intelligence on Soviet activities during the Cold War. 
2. Operation Foot: In the 1990s, MI6 carried out Operation Foot, a covert operation focused on countering the illegal proliferation of weapons of mass destruction (WMDs). The operation primarily targeted individuals and entities involved in the smuggling and trafficking of WMD-related materials, particularly from the former Soviet Union. MI6 collaborated with international partners, including intelligence agencies and law enforcement, to disrupt and dismantle networks engaged in the illicit trade of WMD components and technologies.
3. Operation Mass Appeal: In the early 2000s, MI6 conducted Operation Mass Appeal, a covert propaganda campaign aimed at undermining al-Qaeda's influence and recruitment efforts. The operation involved disseminating false information through various channels, including websites, forums, and media outlets sympathetic to Islamist extremism. The objective was to create divisions and distrust within al-Qaeda ranks, divert resources towards internal conflicts, and ultimately weaken the organization's ability to carry out terrorist attacks.
